Hi, as mentioned in an earlier post, I’m building a kit from Yank Model Research, which dates back to 1947. The windows and doors are partially cut through, but no way near all the way, as in today’s laser cut kits. I’m having a difficult time cutting with an Exacto knife, as the wood is almost 1/8” thick. Was there a technique that made this easier? I can’t imagine it was easier back then, but I’m hoping some builders on here can offer some advice. Here’s a shot of a typical wall I need to cut out.

Thanks, Artie

1/8 thick is quite a bit more difficult than 1/16 which is more common. Mark the four sides with a pencil. Make a short 45-degree cut starting at the inside of each corner using the end of the blade. Then do the same along each edge. This helps to prevent the wood from splitting when you make the final deep cuts along the edges. I use a metal straight-edge and cut against it on each side - a little depth at a time. It can be a lot of work to do this. Take your time. Be sure to wear safety glasses and never cut towards yourself when doing this.

Well us old school guys would use a hand coping saw or powered jig /scroll saw.

Simply drill a 1/4 inc dia. hole in the window, thread your coping saw blade through and re-connect the coping saw blade to the coping or jig saw.  Saw out the window and disconnect the blade to remove from the hole.  Repeat for all windows or door.

I started making holes like this when I was 6 or 7 and used my Dads old petal power Jig saw, like below.
