Hold Down Clamp

[rwm]

I decided I need a hold down to fit in the T-slots of my drill press table (if you have seen my faceplate in my Clausing thread you know what I mean.) I have been fascinated by the construction of Kant Twist clamps. They use stamped out sheets and spacers to create a rigid 3-D structure. I got thinking..."ya know I have this old stainless steel grill...and I have some home made 85,5,5,5 brass....

Probably overly complex for a hold down clamp. Looks cool and works great!

Nice design ... especially the wide cylindrical base and the pivoting foot for the workpiece. Might I offer a suggestion? Consider replacing the socket head screw with this tool-less clamp (might have to re-machine the T-nut with M6 thread):

Depending on the cutting load, I'd reverse the two ends, but the short end holding the part. MOre clamping pressure that way.

Great job making it, bye the way.

It is easily spun around if you want the larger feet on the work and more force. Also you can drill between the arms if necessary.

Great idea and good work.
I may just have to make a few of these.

Hi Robert, Guys,

Very spiffy ! I like the large clamp head.
I made some clamps quite similar some time ago, specifically for securing some plate to the mill bed.
Here is a picture of mine:

Nowhere as pretty as yours.

Baron- I really like that one also. Heavier duty. Maybe my next one!

Hi Rwm, Guys,

Somewhere I have the plans/notes for them if you want them.

Thank you but I will just "wing it" on Fusion. Sigh, I only I had a CNC laser cutter...
BTW- the cost of this was $0. Stainless from an old grill and brass from salvaged copper pipe.
