This contraption is a solution to not having a third hand! It is a little jig made from some scrap plywood, a couple of bicycle inner tubes and some padding. This device can also be a good helper device for roughing out blanks for carvers who don't own a band saw. I cut a couple slots in the plywood and found some foam rubber laying around the shop. For hold down "clamps" I chose some old bike inner tubes - free from a local bike repair shop. You could also use an old belt or strap or even a length of rope. Clamp down the jig to saw horses or a bench or table top. Feed the straps up through the slots.
Lay the carving blank under the strap loops and place some pads under the wood. Now all you have to do is put your foot through the loops and apply pressure to hold down. You can easily apply as much pressure as you need to offset the force of carving. When you need to rotate the blank, just let up on the foot pressure and adjust. Very fast and simple. It can be made to work standing or sitting down. Best of all, no dents in the wood and no worry about hitting a metal clamp with one of your tools. If you cut the rubber tube - so what? I find this jig to be very flexible and the technique removes wood fast! You have both hands on the tool and with most woods, you don't need to use a mallet.
