Grampa Pete's Blog » How to Build a Bench Mold

I use dense pressed board 1″ thick for ease of carving the bottom of the mold ( top of bench). The top can be either plain or with a carved-in design. It needs to be in profile so it doesn’t stick up too far. ( Hard to sit on those large bumps).

If you use letters or numbers in your design be sure to remember that you are looking at a negative so everything will look backward.

After carving and sanding your work you should put on several coats of tough varnish or enamel.

The sides of the mold I made of straight grain fir and put radius top and bottom with a router.

Sand your work and put on several coats of varnish or enamel. I use hangar bolts to fasten sides to the mold. You can use the same bench sides for any of your benches.

    Dear Grampa Pete,

    This was awesome to see. I am delighted to have come across this site ~ thank you. I am inspired to try and make one of these myself this coming summer. I was wondering about dimensions of your frame pieces… Would you be willing to share the height, width, and lengths of the frame pieces…? Also, if you have profiles and/or dimensions of the feet that would be great too.

    Thanks so much for sharing! I love your pothead as well!!! Could you please tell me what material you use for the actual mold? I want to make a pothead so badly and am trying to figure it out but with no luck. Appreciate any help.

    Hi Carlton,
    The product we used is a Smooth-on product called Rebound-25 from Smooth-on in Spokane Wa. We will have a book out in about a month explaining all this. I hope this will be helpful.
