When you guys scratch build from plans, what is the procedure to create templates ribs and such? do you cut the ribs from the plans for paper template or ....?

Some do and some get photocopies done of that area of the plans. If you go with the photocopies for templates be SURE to bring along a ruler and check the size of the copy to ensure it is accurate. If not you can fudge it by either cutting to the outside of the lines or if the copier has infinetly variable sizing you can set it to 101% or 99% or whatever is needed to produce the most faithful copy size.

I used to use carbon paper as a kid and for many years. But these days it's impossible to get good, soft grades of carbon paper. When I found a pack a year or so back it took such a strong pressure on the paper to make the carbon mark the wood that I didn't need the carbon since the lines were embossed on the wood.

It's primitive but I've found that I just place the plans over the wood and then poke a series of pinholes through the plan and into the wood. Then I lift off the plan and "join the dots" using my Xacto knife or a ruler and knife for the longer straight stuff. It sounds bad but really it doesn't take as long as you would think.

I was thinking, especially for a model you wanted to build several copies of, a thin ply or aluminum would be the ideal template medium.

IF you KNOW you'll build more than a couple then yes, aluminium or plywood templates are not a bad option.

Alternately if you KNOW you'll make up around 10 or more over a few years why not make up jigs to accept stacks of slightly oversize roughed out parts which then get a final trimming using a piloted router or similar tricks to produce stacks of parts.

The problem is that jigs or aluminium templates all take FAR, FAR longer than cutting out a few parts. If you like the design it's not a lot more work to use the final part as a template to make one or two more. Then simply put the one or two semi kits away until needed.

Some photo copies will transfer the inked image onto another surface when ironed. I have made templates that way. Another tactic is to use a "pattern makers wheel". It is a wheel on a handle with lots of little spikes like a rowl on a cowboy's spurs. You follow the line on your plan and the surface below gets a string of dots.

if you think you may ever make more than 1 of the plane from the plans is to have a working copy made. if all of the ribs are same size I make 2 patterns of the ribs, stack ruff cut ribs between the 2 patterns, bolt patterns together and sand to finnal shape. I use a local mom & pop printing shop to make the copys. by makeing a working copy your original plans are never mess up. no matter how you cut out the parts I would never cut up the original plans.

In a pinch you can trace the parts from the plans onto paper. Holding the plan against a window (I have a large glass panel door) works really well. Just lay your blank paper onto the plan and have at it! I'm a frugal cuss!

See Temp would be a good choice but if ordering from them online watch out for the shipping charges! I ordered 5 sheets. They do not tell you the shipping cost but add it to the credit card when they ship so you have no clue how much it will be. Shipping on mine was almost as much as the SeeTemp itself. As I recall, the 5 sheets were $30 but shipping was $20 or something like that.

I have seen references to it being available in some fabric stores. When I went to SeeTemp's website I got the impression that SeeTemp is under new ownership so I do not know if it would still be available at some fabric stores or not. It might even be available at some local hobby shops.

SeeTemp is a good product.
