Replace all the square nuts

After enough aggravation tightening those horrid square nuts on my Mark V bench, some years ago I replaced them all with elastic locknuts. These are the kind with the plastic band which elastically engages the threads. Sold under the brand name ESNA and made by others as well. These really stay tigh...

Router Sled for Lumber

I recently designed and fabbed a router sled. A router sled uses a router mounted to a sliding or rolling platform to shave a flat surface on a workpiece. Youtube has numerous videos of router sleds built by others. Most of these are used to create flat table tops from tree stumps or wood burl. I sp...

Re: Thermal Images After Rebuild

How did you correct for the emissivity of all those different materials? For instance V-Belt vs metal case. I like the convenience of an IR image-but it can be wrought with hidden difficulties.

Re: Thermal Images After Rebuild

I didn't see anything I'd worry about, just curious. I agree with jpg regarding floating sheave. If ...

Motor Strain Relief

Just finished a headstock rebuild and wanted to replace the motor cable strain-relief bushing. After much plier and screwdriver work I finally got the strain relief out but beat it up in the process so of course I wanted to get a new one. The original was made by Heyco. My pliers wiped off the old p...

Thermal Images After Rebuild

Just finished a headstock rebuild. All new bearings and belts. As a check, I took some thermal images to verify no unusual hot spots. Images attached as PDF. Everything runs OK but I now have a speed control problem where after running at high (P-Q) speed, the speed did not want to come down. So I d...
