How to Make an Airship Model

This construct is mostly wood, with papier-mâché for the balloon and the base shell of the gondola, and mesh sandpaper for the deck floor (to mimic the cross-hatched wooden cargo doors on an old deck). It took a couple of nights to make, but  a lot of that was walking from basement to top floor scouring the house for possible materials, and waiting for glue to dry…

materials

I did not really start off with any materials in mind. I had bought some of these supplies for something similar a while back, but a lot of these I found around the house as I went – so, just because I used them, doesn’t mean you can’t find something better. I am a starving artist, and also having to use what is handy because I am working after midnight, after most stores have closed. Feel free to substitute – but I have found up-sides to most every improvised material and I will try to elaborate as I go. Materials: 1) Two pre-made papier mache eggs – one large, one small. If you cannot find them pre-made at your local craft store, you can make them by simply layering papier mache around a party balloon. I used the large egg for the balloon, and cut the small egg in half to make the gondola. 2) One large wooden dowel (1 inch diameter), Eight small dowels (1/4 inch diameter or 3/16ths) 3) A spool of wire. I used framer’s hanging wire because I had some handy. 4) Drywall screen. It is a type of mesh used for sanding drywall – a fabric screen coated with abrasive crystals. 5) Some thin wood panels. Modeling stores have them, crafting stores have them. They are typically used for everything from model ships to doll houses. I cut the propellers out of these. 6) A packet of small hardwood spools 7) a packet of hardwood “pickle barrels”, 8 ) a packet of wood beads. 9) Glue – the stronger and harder the bond, the better: Gorilla glue, Tacky glue, Elmer’s glue all… 10) Paint – you’ll probably want to paint yours. I recommend some cheapy apple barrel or comparable acrylic craft paint. For the demo, I am painting everything black, but I will eventually go in with browns and brass colors to finish the job. Tools: 1) Two pen knives / craft knives. I use them for moving small parts, holding other pieces in place, and of course cutting things. 2) A drill, or a drill bit will come in handy. If you have a power drill it does come in handy – but you can make due with a drill bit stuck in the end of a wood dowel. Match the drill bit to the size of your smaller dowels. 3) A pair of shears or tin snips or some really good (or really disposable) scissors. 4) a coping saw or other fine-bladed crafting saw. To Begin: There are a few steps I do not have pictures for (but will correct this when I start the next one. I didn’t at first plan to make a tutorial of this (sorry). 1) The first thing I did was to cut a hole in the top the big papier mache egg. I made the hole just a little bit smaller than the large dowel. I then cut a hole through the other side of the egg, and pushed the dowel through. This is the mast and (possibly) smoke stack… if you want it to be a smoke stack… I won’t stop you. Either way, it is a big pole going through the balloon top to bottom. Make the big mast long enough to protrude from the top, and from the bottom about 3 inches. This mast will also be the main thing holding the gondola onto the balloon. 2) I did the same thing with the small dowels – making holes with my pen knife and poking the dowels in – one long one in the front (foremast), two in the back (for the tail – one straight out the back, one higher up), two on each side (to hold the sails) You can look at the second image down to get the general feel for where I put mine. I made them go deep into the Egg for more strength.

Bead
Balancing the bead on the tip of the knife is easy, especially if the bead has holes in it. The spots of glue you press the beads into will pull the bead off the tip of the knife pretty easily.

3) To strengthen your masts’ joints with the body, pour glue around where a dowel meets the balloon. Then, with the pen knife, add beads around the mast. This mass of beads and glue will make a nice collar to keep the mast from sliding back and forth, and it will also reinforce the balloon where they meet (see image below).

4) For the gondola (above) I cut the smaller egg in half. I also cut a round hole through the bottom where the large mast will just barely pass through (enough to give it a strong bond). 5) I cut a little semi-round divot out of the back and glued a barrel into it (the main boiler). I then glued a barrel in the front to balance it (it also makes a nice wheelhouse). From there, I covered the top with my drywall screen, which a cut with a pair of tin snips. 6) Engine assembly: two short bits of the small dowels on the sides, one as a cross-pipe, and two pickle barrels make the main engine assembly. I drilled holes into the sides of the pickle barrels so the crossbar could be glued in securely.I also drilled holes in the back-ends of the barrels so that I can put my propeller shafts into them. 7) For a touch of added decoration. I also added some wood beads to the top of the assembly. 8 ) The rest is just decor – wood beads cover where the mesh meets the egg, little wood pins add a touch more decor to the deck, a thin shim of wood and some more beads makes a solid walkway to the wheel.

propellers
propellers

9) For the propellers, I cut two of the small spools in half with a coping saw. I drilled my hole through first – and then I fond that I could just leave the spool to spin on the drill bit while I pressed the blade of the coping saw against it. It worked like a mini-lathe. Follow my example there at your own risk – it may be dangerous. 10) I then carved 4 thin propeller blades from the thin wood slats (using the utility knife) and I glued them to the top of one of the spool halves. Then I glued another spool half on top of the propeller blades, sandwiching them in between. 11) Repeat the above step for a second propeller.

12) I cut the ends off of another spool, and used them as end-caps on a 3-inch piece of a small dowel. Again, I drilled holes in the spool first, so the end caps will go around the shaft. These end caps will allow your propellers to spin freely, without the worry of them falling off.

13) Lots of black acrylic paint. When adding a patina to anything, it is often easier to go black to light, especially when it comes to acrylics. Slather the stuff on – not only will it add strength to your construct, but it will smooth out the surface of the balloon.

Unwound Wire

14)  I cut the sails from the drywall screen (abrasive sheets). I pretty much just held them up to the masts I had made, and cut n small steps until they were just how I wanted them. Then, when the sails were the right size and shape, I tied them to the masts with thin wire. I did not have any thin wire handy, so I unraveled the framer’s hanging wire. I tied in about 4 spots per mast. If it is hard to tie, you can twist the wire instead… that may even be better. 15) For the jib sail, I had to secure some of the thicker wire between the top mast and the foremast, so i could have something to tie the sail onto. You could probably use a really thin dowel for this and have a *much* easier time.

Wire and Mesh

15) With the sails tied on, I poured glue through the sails where they met the masts and cables. The nice thing about having used the mesh – the glue passes right through the holes.

16) I put the propellers onto the shafts I had previously end-capped – make sure the holes through the propeller are big enough to allow for spinning (they should be if your drill bit is the same size as the small dowels). If not, give them another pass with the drill… some glue might have gotten in there, or the pieces might have shifted before drying. 17)  If they spin, or if you don’t care if they spin, you can now glue the shafts into the holes at the back of the engine assembly.

18) Done… or for the most part. I have ideas on what color I am going to paint mine – but you know the principle: put paint on a brush, brush paint where you want it – use smaller brushes for details,  bigger brushed for bigger areas – ‘not too much more I can tell you there.

I’ll post pictures of mine when I am done. For tonight, I have to let everything finish drying…. then off to the World Steam Expo on Wednesday night/Thursday Morning.

Custom Framing on an Artist’s Budget

One of the more painful and costly steps along the way to an art show or convention for us, and other artists we know, is most always framing.

It seems that artists and artisans anymore, can be some of the most heavily exploited tradesmen when it comes to tools and supplies …and frames are certainly no exception.

Art supplies tend to be priced for Warhol-famed artists, design agencies with multi-million dollar clients, or students who simply have to have these things, and will have to take out loans and grants accordingly; Frames are often priced for artists of Ryden renown, or remarkably wealthy art buyers – factor in huge percentages for art sales through galeries, and it is no wonder that the gallery owner lifestyle of nice cars and sipping champagne contrast so beautifully with those of the artists supported: which I suppose for most of us… well, I don’t know how you get by, but lets say “robbing liquor stores for brush money” as a rather broad example.

And since for any show or convention it is good – if not mandatory, to have hang-able art. Many of us artists need to get creative if we wish to account for a 40% cut on sale price, and frames, without demanding a “Just who does he think he is?” sort of price.

One route, of course, is to gallery-wrap, or museum wrap paintings and giclees in a way that makes for a nice display without the need of a frame. Add a touch of color or a reflected image to the overlap, and such things do really tend to look very nice… though modern by default. Gallery wrapping and museum wrapping is available as an option for ready canvas through most any art supply provider, and having giclees stretched these ways is an option with most decent giclee printer. Doing this one one’s own is moderately difficult for gallery wrap, and strenuous for museum wrap – but by no means impossible.

If however your works are already stretched and mounted, with staples down the sides, or if they are painted/drawn/engraved on boards or paper and absolutely need to be framed – there are still a few creative, inexpensive, and simple ways to go.

One of which – if your works will fit standard frame sizes, is to go on “50% off!” weeks (we like to call them “regular price weeks”) to Hobby Lobby or Michael’s and buy their pre-made frames. Another solution of course is to go to places such as Target and Walmart and browse, looking for discounted frames that can be redecorated and customized to look nice… perhaps even to become works of art in their own.

One problem I have found with many of the ready-made frames (and even many custom frames), something I particularly dislike, is that I find many of these frames are either plastic, or low-grade wood, either made to look like better wood by way of plastic/acrylic veneers or overlay, ornate clay designs painted or coated over, or by other means. The most standard being those which are low-grade wood with the clay and paint overlay, which tends to chip and break in shipping… if it isn’t already broken in this way at time of purchase. The ones at non-art stores tend to be plastic molding with a plastic wood-grain sheet ironed onto them… again… trying to avoid that.

So, yesterday, after browsing many ready made frames at all the aforementioned stores, not finding anything I liked at a reasonable price – and finding mostly overpriced junk, I decided to try to make my own.

The first step was a trip to the hardware store for lumber, where I purchased four 6’x4″x1″ pieces of wood.. having struck out on all avenues in looking for a source for the wood strips framing galleries use. I’ll have to try that some other day.

So… wood…

I’d like to say I went for the fine cherry, a nice fire maple, or something moderately exotic – but what I ended up going for was a compromise.

At Home Depot, I found their “exotic wood” be be very exotically priced. I am used to prices being high on hardware at woodcraft – but Woodcraft’s prices certainly beat (by light years) the wood prices at Home Depot. I will have to remember: Woodcraft for wood, Home Depot for hardware.. but, of course it was late at night when we went… So Home Depot was pretty much where we were going for the lumber.

Pine being cheap and sub-quality wood, I looked to avoid that route – but in the good wood section I found what is called “select pine” – which is not quite gold-grade heartwood pine, but certainly not shabby construction-grade pine. It is nice and heavy, very dense actually, with a really fine grain and very tiny knots. I was rather surprised by how sturdy and dense it was, and at $4.19 a  6 foot piece – I decided to give it a try (and having tried it, I am actually quite happy with it).

[Edit] Having returned, and taking a closer look at Home Depot’s stock, I also found some really nice Maple there for about $1.40 a linear foot – still more expensive than the pine, about twice the price but certainly not bad. I also found cherry and red oak shelf capping for around $1 a foot, which I plan to use in future projects in place of the moulding below.

I also grabbed some decorative wood strips from Home Depot (sort of like above, but not the same design)… rounded and decorative on one side, flat on another. My plan is to use these to make the frames a touch more ornate. The price wasn’t bad.. $2.16.. Oh? Not “per piece” .. that’s a linear foot? Okay… I bought one six foot section. Also in my arsenal is some brass chain at Hobby Lobby (clearance priced)… about 120 inches of it. Home Depot had wood appliques – but their prices on those were ridiculous – I am supposing they were trying to get as much as possible out of cabinet makers. The things are incredibly cheap by comparison at Michaels… I’ll have to go there tomorrow, as they didn’t have them at Hobby Lobby and I wasn’t about to pay the Home Depot price for them.

So… first step: Cutting the wood

So… first step… measuring the wood.

These artworks are 5×7 inches. So, I want the inside of my frame to be about 1/8 of in inch smaller than that. Typically I’ll sit there and figure up the best mathematical formulae to get the perfect result – but diving right in, I simply measured 1/8 of an inch in, and used my 45-degree plastic triangle to mark where the first 45 degree cut would intersect that drawn line. I measured 6 + 3/4 (7 inches minus two times 1/8 of an inch) of an inch along that line, marked that point, and used the triangle to draw a line where the next cut would go.

From there I carefully and precisely made the first cut on the table saw, using my 45-degree angle-guide. Then I carefully and precisely made my second cut. From there it was just a matter of sliding forward my 45-degree guide, placing one edge against the (stopped) table saw blade, and lining up the straight guide to the end of that piece. After this I could just cut, flip the wood over, cut, and flip the wood over, making perfectly identical trapezoidal wooden pieces… my 7-inch sides.

Table Saw: The same 45 degree jig and same position as the very first cut. The difference is the piece is flipped and moved to the guide in order to reflect the opposite angle, and the achieve the right length. This can also be done with a miter box, but the table saw really makes it go much faster.

After cutting the first two, just in case my angle guide was not entirely accurate, I matched up corners on the cut pieces, and checked them with my triangle, to make sure they were squaring up. They weren’t. So I made an adjustment of half a degree – and used these pieces over and over again until the angle was perfect.

One of the cut pieces. Remember - Trapezoid, not parallelogram. No adjustments need to be made to the guide for this, just flip the wood. Also note my sleeves... not recommended for anyone without a death wish. Loose sleeves, long sleeves, are not the best attire for workshops.

I made 18 of these long sides, saving the first two ‘test pieces’ for use in making the shorter sides, since they were shorter after all the test angling.

Then I made the 5-inch sides, in the same manner as above, until I 18 of those as well.

After this, I needed to make it so that the artwork could rest inside the frame, meaning that 1/8 inch recess (rabbet) planned for needed to be carved into the inside dimensions along the back of the frame-to-be. This is a good time to have a router (and a router table is all the better).

*If you do not have a router, which I am sure a lot of you may not, I would recommend starting with decorative beading (the sort of trim that, in a house, runs along a floor or a ceiling… available at most lumber stores). From there you can just build a simple square and square-edged frame for your work, with the inside of this being the exact size of your artwork (n0 need for a rabbet), but use the measuring and cutting steps above on the trim. The trim can be assembled on top of the box frame, glued, pressed, and clamped for a very nice look and sturdy frame. Those are the basics… I’ll go over that particular method in more detail, but it will have to wait for another post*

Router and Router table - I set up two guides for this one. One to set how far back towards the bit the wood piece can go, one to keep it down to the table (while at the same time to keep my fingers away from the bit)

I used a router bit which has a curved into flat bevel, called an “ogee”. The flat edges would hold the artwork well, and the rounded surface would allow for the least amount of surface contact on the art side of the artwork.

Routed edge - better than a rabeted edge, because the curve keeps more of the arts surface away from the frame itself, which prevents a rubbing on the art surface.

I also used this same decorative “Ogee” bevel on the inside front as well. As a bonus, being the same on the inside dimension front to back, I could choose which side looked the best (according to the smoothness of the cut, the look of the grain, dents and dings, etc.) .

Having chosen which side would face front, I then took to beveling the Outer Edge on front side, giving it a smoothed and decorative face on the front (inside dimension and outside), but leaving the back flat and flush. For several of my frames, I also made the back outer edge beveled as well, giving the frames a nice rounded edge.

Three routed edges - two on the inside near the artwork, one on the front and outside of the frame. The fourth edge is left plain so it can be flush with the wall.

Once I had all my pieces done, I quickly sanded off all frayed edges and burs from my cuts, so the frayed ends would not get in the way of the next step: gluing.

Glue, actually holds more securely than nails or screws, if done properly, and of course keeps unsightly nails and screws from your frames. Such also negates the risk of splitting your pieces with such fasteners during the construction process.. which would be a terrible waste of all the work done up to now. There are special fasteners for framing (to be used later), but the glue is most important.. and will make that fastener step much easier if you choose to use fasteners.

I used a four-point box clamp for this. It makes jobs like framing, assembling stretcher bars for canvases, making boxes/cabinets, all go much more smoothly with these sort of clamps. If you don’t have them, I’d recommend using two (preferable four) bar clamps or pole clamps for this step.

4-way clamp around the frame, glue at each edge. The pressure pushed glue deep into the end grain, giving the frames a very strong and sturdy bond.

Put glue along the ends of each piece, in thin streams, but try to cover most of the ends, and try as best you can to get the very edges of each end. Clamp them together, make sure all pieces line up square and even. Un-clamp and re-clamp if necessary… Such is much better than letting it dry uneven and having to redo this step or sand things down.

Let the frame sit this way for at least a half hour (preferably longer) before moving it. If it has only been sitting a half hour, remove move it carefully and then leave it be. You will however get better results if you leave each frame clamped for an hour or more. I plan to use 3/8 corrugated fasteners on each corner – they aren’t completely necessary, but they give a bit of added peace of mind to neurotic people such as me.
