Title: Scratch building
Post by: John Miller on September 01, 2009, 04:30:54 PM
I started a new build today. I decided to build from scratch, rather than having the parts laser cut. I took pictures to illustrate the process and offer them here for whatever the value it may be to help my fellow modelors.

The plane is a design for a Fantasy Scale Stunt plane, called Zweipanzerflug. I've posted some info on it before.

I always draw a pattern sheet for the parts. The trick is to cut the patterrns out and use a light coating of 3M77 to stick them to the wood. Notice that the parts are all laid out as they would be on each individual sheet of wood.

Next, useing a band saw for the larger parts, and a dremel scroll saw for the smaller ones, I'll cut out the individule parts themselves. I don't try to cut exactly to the lines. I'll use the disk sander for that chore.

A few houirs of enjoyable work, and I have a kit.

I store associated parts together in plastic baggies. It helps me keep track of them. H^^

John, what is a Zweipanzerflug  ???  Sounds like the german name for a panzer tank, and what does it look like?  I know it's a fantasy scale stunter, but that's it

Matt, I forgot that you joined the forum long after I posted some jpegs on the Zweipanzerflug. BTW, loosley translated, it's suppozed to mean 2 Flying Panthers. The fantasy part is it's my ideas of what WW2 German aircraft engineers might have developed as a dual role close support/air superiority weapon, after studying smuggled plans for Grumman's F5F.

One of my goals with this post, is to show that using a pattern sheet, it's possible to hand cut parts nearly as accurate as Laser cut parts, with a minimal time investment.

Any way, here's a jpeg of the main plans sheet.  H^^

Thanks John.  That plane looks familiar, hmm, gotta get the world war II books out.

Well Matt, did you find the German design that served as inspiration? #^

John,

This is pretty much what I always do (without the pattern sheets). I draw plans (in my case by hand), go to the copy shop and make usually 2 copies (sometime three depending on the layout). Put one on the wall and cut up the other one (or two) to make templates then start cutting wood.

It can go pretty fast even with my admittedly bizarre structures.

My new PA plane is just about framed up.

Yep, it can go rather fast when you're set up for it. BTW, I like your bizarre complicated structures. It reminds me of the old engineering bridge models, and I mean that as a compliment.

To me it looks to be between a Focke Woulf 187, or a Messerschmitt 410.

Very good Matt, it was the ME 210, and later 410 that served as inspiration. #^

Well, that's were I learned most of it. Building those bridge models. Fun stuff.
