Scratch Building Help

Can anyone suggest the best method of transfering the shape of a win
rib from a plane to ply or balsa for cutting (cut out template and glu
to rib, transfer using carbon paper etc etc).

I assume you mean plan to ply. I use tracing paper or photocopy it and then cut out the design and tack with non permanent adhesive to balsa or ply.
Photocopying should be used with care if you want an EXACT copy as copiers dont ever give an exact copy.

Thank heavens the USA hasn't discovered and packaged Rugby.

Here are some of the methods others have listed: 1. Carbon paper 2. Acetone or other solvent to bleed the plan onto the wood 3. Pinhole tracing - poke a series of pinholes on the outline of the part with the balsa underneath 4. Photocopy, cut out and spray glue to balsa 5. Photocopy and use an iron to transfer to balsa 6. Buy a second plan and do #4. 7. Trace part onto See-Temp. 8. Measure and re-draw each part.
I don't think there's any real "best" way. Each method has its advantages and disadvantages. Do whatever works for you.

Something that has worked for me for small things is to
Trace the drawing with tracing paper. Turn the paper over. Rub Number two pencil lead over the lines of the drawing. Turn the paper back over and place on the wood. Then Retrace the original drawing, pressing down with a measured amount of pressure.
The pencil lead on the underside of the tracing paper will act like carbon paper and transfer the image to the wood. It works for me.

Look through the magazine "RC Report" and find the ad for a product called "See Temp". It's a translucent semi-rigid plastic that is perfect for making templates that can be re-used to make more than one part. Being transparent, all you do is lay it over your shape and trace the edge with your xacto knife. Then, just bend and break away the template and go for it. For $22, you get 5 big sheets (about 5 feet by 2 feet) that will last for a long time. Nothing else is as easy or as good for the purpose.

I use freezer paper. It is semi-transparent and plasticized on one side. Place it over the plan, paper side up and trace the part onto the freezer paper. Now, move this piece of freezer paper onto the wood so that the plasticized face is against the wood. Using a covering iron set to about 400 degrees (quite hot) iron the freezer paper onto the wood. It will stick quite well actually. Cut through the paper and into the wood with a knife or use a scroll saw. After the piece is cut out simply peel the remaining piece of freezer paper off the wood. This method works like a charm and the paper is only a couple dollars for hundreds of feet.

I don't know what your talking about when you say freezer paper. Is this something to wrap food up with before you put it in the freezer? Next question, what is the brand name this product goes by and will grocery stores have it or will I have to go to Wal Mart or Target?

I put the plans on a copying machine and use spray adhesive on the copy to attach it to the wood.

Freezer paper is what many butcher shops use to wrap meat. It's plain white paper one side and wax coated on the other to keep moisture from the meat from soaking through. For this purpose, I guess you'd draw on the plain side and iron the waxy side to the wood.
I'm not sure where to buy it. I only see it behind the meat counter and in the deli at the local grocery store. I'd go to the meat counter and ask if the store sells the paper; much easier than searching the whole store.

Once I got past the freezer paper, I learned how to modify you trick a little. I copy the plans, extra dark, and IRON the toner onto the ply I use for the first and end rib guide forms. Got to sand it clean before you iron or the toner will not transfer well. I also shoot a copy at normal darkness to cut out (with scissors or course) and lay down on the prepared guide forms.
Good luck
