I mainly use 1/8th due to the hole being so easy to weld up once complete...... Very good tools to have tho i dont know how i went so long without them. Do the used ones seem to have plenty of clamping force still Chris??? If so ima order up a 100 or so.

They all seem in good shape, some hardly even look used. I haven't clamped anything with them yet so I can't really say for sure about the clamping force. Hell even at the cost of the new ones you can get alot for $25.
The Yard is by far the cheapest place to buy your sheetmetal tools! I have used them for years on aircraft. They have a roving truck and trailer that come to many of your towns and set up at the airport. Check on this. You will be like a kid in the candy store. They have new and used tools. All worth every penny you will send.
