Default How to build dummy ww1 1/3 spandau guns

I'm past my spending limit and need to build 1/3 scale guns. Any advice on an easy approach to building a spandau machine gun. Maybe someone has a build forum Icould be directed too?

Well, let's see, a pair of 1/3 scale Spandau kits from BUSA would run about $60 plus shipping. So that's the price to beat. Luckily it shouldn't take more than some scrap wood and maybe some aluminum sheeting to make a respectable set of guns.

http://shop.balsausa.com/product_p/g904.htm

With good reference drawings blown up to 1/3 scale you shouldn't have much problem making the receiver parts or the barrel. The tricky bit is the slotted cooling jacket. Unless you were going to get this part laser cut (involving both time and money) the best bet might be to make it from lithoplate/aluminum sheeting. I've done this on a much smaller scale with a scratch-build Madsen machine gun but some variation on this theme should work for the 1/3 scale Spandau. The key is finding/making a tool to cut the slots.

For 1/3 scale, how about using manila folder stock for the sleeve; brass tubing sharpened and shaped into an oval for the punch. Then dampen, and roll.

Or find a small company that can CNC it for you

For our project (5 1/3th scale D-VII's) we are also making our own Spandau's. The CNC aluminum plates did cost us about $7,00 each incl. material. I can't make it for that money. I have 10 barrels ready now and now we only have to make a mould for the housing.

That should work fine. The way I've done it (for 1/5 scale) is to use a punch on both ends of the slot then use an Exacto knife to finish the slots. Otherwise, just like you say. Very thin lite ply would maybe work better on 1/3 scale. That's what the laser cut AZM barrels are made from on their 1/3 gun kit, but card stock is used on the 1/5 scale.

I can speak for their Spandau kit, but I've built their Lewis Gun in 1/3 scale. It was nicely done, just very basic, not much detail.

You might also consider Arizona Model Aircrafters Spandau kits ($59.00/pair). While not totally accurate, there's a nice amount of detail, and they (at least used to) come with leather MG belt and brass shells. You can view the instructions on his web site. That being said, a word to the wise, if you decide the AZM route, make sure they are in stock before you order, or you might wait a long time to get them.

The challenge is (always) how to make wood look like metal. Seems like no matter how many coats of primer you use, wood always looks like wood. []

I know that Del Johnson used the Balsa USA guns on his GMT 1/3 Fokker Dr.I, and showed the results on his build thread here:

http://www.rcuniverse.com/forum/m_43...29/key_/tm.htm

and continues through about page 33.

Seems his biggest issue with them is that they are very labor intensive to get sealed, but with the effort they do turn out nice.

Best regards,

As far as AZM, try this.

"http://www.rcuniverse.com/forum/m_7714698/anchors_7714698/mpage_1/key_Arizona%252CModels/anchor/tm.htm#7714698"

Unless things have taken a 180 turn.

Scratch building is the best route to take. Yes, they are labor intensive but the result will be much nicer than any other kit on the market. These are what I put in my 1/3 Fokker and took about 80 hours.

Beautiful work! Not many modelers have that kind of patience (or skill). How did you make the cooling jacket?

Thanks, Abu. The cooling shrouds are made of .020 styrene plastic, capped at both ends using 1 1/4 brass faucet pipe. I had to drill all holes in the styrene, then painfully cut from hole to hole to form the slot. Faucet pipe slots were milled. The receiver housing is balsa construction similar to the BUSA and then covered in styrene so there is no major filling before prime. Most other parts were made from a thicker styrene. The ends of the barrels are made from CA tips and, believe it or not the cap on a Vicks nasal inhailer (cut the top of the cap off). They are holding up very well after 4 flights and I have not had any problems with them falling apart.

That's the beauty of this hobby. Seeing the result of craftsmen using the mundane everyday objects to recreate in small scale the items of necessity for our planes. Ecellent work there C'hook!!

Will anyone ever step up to the plate and manufacture a GOOD set of third scale guns. Now that would be nice, and sure make it a little easier on us German aircraft builders. I'm hoping GTM will some day do this. But for now we are stuck with making our own or modifing Balsa USA, or AZM take your pick. A year ago Glenn, of GTM was getting his prototype 1/3 rd scale D-7 ready for Top Gun Team Scale entry for which I was the pilot. Glenn had no guns on the plane and not enough time to build a pair so I stepped up to the plate and made a set starting with Balsa USA's kits. Here is the build of those guns, along with the changes and added details to get them to a rather respectable gun used on a Top Gun Plane. By the way we ended up taking first in team scale, a first for WW-1 aircraft.

Once again we have proof that the solution to the question of "where can I get scale X" is BUILD (OR MODIFY) IT YOURSELF! Outstanding work! And, besides, it's there so much more satisfaction in building something like this yourself? I believe the "behavioral economists" refer to this phenomenon as the IKEA effect.

Great work Tom. I'm just starting a set of guns for my Albatros. I will use your pics as a guide. Now if I could only machine all those bits half as good as you did!
