I have a spare (not new) Idler, the Control Sheave measured 0.626" bore with calipers. The shaft actually measure the same with the same calipers. Subjectively, I don't feel any slop. So I agree 6 - 8 thousandths seems excessive. I have not heard of using shim stock for this. - David Thank you...

Rebuilt my Mark V headstock but still had speed control problems - idler sheaves were jamming open at speeds above "P". See attached PDF. Pulled the headstock apart again and had a closer look at the idler sheaves. Measured 6-8 thousandths diametral slop between bore and shaft which I thou...

I'm the OP that started all of this, so let me try to fix it... We make assumptions when measuring anything. We assume our ruler is "perfect". Do we all agree that the quill axis is the primary datum for everything on the Shopsmith? We assume the quill axis is "perfect". We also ...

I previously used ordinary folding-leg tables but they proved to be inadequate for heavy work. I wanted a folding-leg table that had a dead flat top, strong legs, and removable casters on the table-edge so I could roll the table instead of dragging it. The result is the table shown. I built two. Top...

I agree with Dennis that you've got an original sled design there with the screed plaster bed. Any idea what the sled weighs? Also, how long is the steel bar you use in the t-track when edge jointing? Router sled weighs about 60 pounds. Heavy. I have to pick it up using two plywood-grabber handles....

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...

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...

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. I would minimally double check some non-moving surfaces with an RTD or thermocouple to verify accuracy. I...

[/quote] In your FLIR images, is the temperature indicated in the upper left box associated with the cross-hairs or pipper in the center of the screen? Was the run time about the same for all images? I didn't see anything I'd worry about, just curious. I agree with jpg regarding floating sheave. If ...

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...
