This is a marking gauge made with wood and alumni. I haven't put the blade on the top. and also i think the twist buttons are too big. so i would improve on the next...
Step 1: Make the Shape on a Wood Lathe
Shape a wood block, i didn't take pic because too much dust at that time. and cut 2 pieces of alumni plate stick on the wood with epoxy.
Step 2: Advanced Step
Use files, sand papers. inside the wood is a 8*6 copper pipe.
Step 3: Almost Finish
Drill 2 holes then. insert the copper nuts and then make 2 wood buttons with screw for lock the stainless steel stick.
