Welding clamps (t-slot)

admin

I found these pictures a while ago.  I believe they came from this Photobucket archive (no longer accessible but you can kind of see them obscured).Are these commercial items or something he made?  The red one looks like a modified C clamp.  He's not been active on that site in years so I didn't bother joining to ask

I know Miller makes something similar but they're $$$.I cut slots in my home made table and would like an inexpensive set of clamps that mount into them.

Reply:I would disregard the tee slots you cut and just drill a pattern of 5/8" holes. You can easily modify any number of clamps available to use without the hassle of using tee nuts (or ANY nuts )Sent from my iPhone using Tapatalk:
