Okay all you puzzle nuts, how about we show, explain, how we go about making our puzzles, our pen friends would really like to see how we go about it, what do you say?....I'd like to see jig pics starting with the most common cut-off jig to the more elaborate Coffin jigs

Scott, pics of your aluminum sled please!

Here's a link to get an idea of the most basic sled designs, and what puzzles can be made with them....;
