ponce wheels and chaulk
I would like to use foam roadbed, so it will have to be glued down to the plywood table. I really need a way to "transfer" the paper template plan to the plywood. Hmmmmm..
There is a tool called a ponce wheel that dressmakers use to transfer paper patterns onto fabric. I think it would do what you want. A ponce wheel looks like the "rawl" spiked wheel on a cowboy's spurs, only smaller, and with a handle. Micro Mark www.micromark.com
is one source, or you might try a fabric store.
After securely taping, pining, or stapling, your track plan to the plywood, you would use the ponce wheel like a pen to trace along the track centerlines on your plan. You will need to press down fairly hard. The points of the wheel will poke through the paper plan and into the plywood. You can make the plan's image on the plywood show up better if you trace the centerlines again, this time with a piece of chalk, a pen, or a pencil. Some of the chalk, ink, or pencil lead, will go through the holes and onto the plywood. This will be easier to see than the faint holes made by the ponce wheel. You could then remove the track plan, and connect the dots on the plywood to reproduce your plan.
Another, simpler, method just occurred to me, Carbon Paper. An Office Depot, or Staples, store may stock carbon paper. You would need a box of it, and a roll of Scotch tape. Tape the carbon paper sheets together, all facing the same dull side down. Into a 4' x 2' or 4'x4' giant sheet. I think a 4' x 8' sheet of carbon paper would be too hard to handle. Put the big carbon paper between your track plan and the plywood, with the flat dull side of the carbon paper facing down against the plywood. Then trace with a ballpoint pen, or a pencil, along the track centerlines. The carbon paper will duplicate your tracing onto the plywood. Move the carbon sheet to the next area of the track plan/plywood sandwich and trace the rest of your plan.
Or, you could just glue the plan permanently onto the plywood, and glue your roadbed and the rest of your layout to the track plan. This would require a good strong glue bond to keep your plan, and everything else, in place permanently. This is possible, but maybe a bit impractical.
Bye the way, I think this whole procedure may be overkill. Most of us just locate the track on the plywood by measurement, or actually lay the track pieces on the plywood and trace, or spray paint, (good opportunity to weather your track
) The track's outline onto the plywood. Still, it's your railroad, and you did go to all the trouble of printing out a 1:1 copy of your track plan.
