I built this dimple die from a couple pieces of scrap aluminium I had. I cut both angles to 45 degrees, took about 20-30 minutes at the lathe and works great on the thin gauge aluminum sheet I needed it for. I plan to make a few more from 4140 and harden them but I think the aluminium will stand up to a few hundred holes or more.
