Deep-well wing nut for drill press locking clamp
I bought these locking clamps to use to conveniently hold things fixed in place while using my drill press:

...however, there was a problem with them. The "wing nut" part could not turn underneath my drill press's table because the deep reinforcing ribs underneath the table would interfere with the wing nut handle. (This is an old school powermatic drill press.)

My solution was to TIG welded some custom "deep well" wing nuts to space the handles out below the table's ribs. I ended up cutting out the threaded portion of the original wing nuts (using a cutoff wheel in an 4.5" angle grinder), and then welded on some lengths of 1/2" OD stainless steel tubing, along with two little handles 180 degrees apart (for conveniently making adjustments with your hands underneath the table... no wrench required.)

I used 304 stainless, 1/16" wall thickness for the materials (the threaded part donated by the original wing nuts were I believe some kind of plated mild steel), and I used 309 filler rod. Instead of cutting away the threaded portion of the original wing nuts, I could have just bought new nuts to use, but I think cutting up the original wing nuts saved me a trip to the store and also I would have had to grind new nuts down skinnier anyway so they wouldn't interfere with the reinforcing ribs underneath the table.
Here is what the custom "deep well" wing nuts look like installed underneath the table:

I used a flap wheel to smooth the edges so there are no sharp edges when grabbing them with your bare hands.
(Sometimes having a TIG welder around can be really handy. ;) )
