Re: Drill Chuck Key Jams

On my drill I measured the pilot shaft and the chuck bore - they are in fact closer than I thought, about .001" clearance (15/64 nominal dia). But the attached photo shows how much play there is - enough to be a problem each time I use this tool. I suppose it could be attributed to a defect in ...

Re: Drill Chuck Key Jams

For what it is worth, I recently bought a DeWalt corded 1/2" drill for cheap (I think DeWalt/B&D is trying to clear out their corded tools to make way for cordless), and the chuck key that came with the drill is a poor fit. Drill has the old style Jacobs chuck. The stub shaft on the key, wh...

Re: Wedding-flower stands

I usually don't have the patience to build fixtures like that beam. A labor of love for sure. I guess one object of the design is to not expose the dowel or any fasteners on the table top, so no thru-bores in the top? That homemade t-slot beam looks good. But may warp over time. 80-20 aluminum extru...

Re: What kind of wood is this?

Saw on it a little bit and smell. If it smells sweet it might be rosewood. If no smell, might be locust.

If you drop it on concrete and it has a clangy sound, might be rosewood.

Re: Mark V Speed Control

If the motor spring will not let that dimension get to 2.08, then that should explain why people cannot get to 700. Mystery solved? As for the belt dropping inbetween the sheaves on the low speed end, I think that could happen but only for a narrow or worn belt (the belt width shown is a full .59&qu...

Re: Mark V Speed Control

For those of us who are measuring geometry within the headstock, the attached drawing is supplied. Shows what the drive geometry should look like, and measure, when running around 700 RPM and using the "Official Shopsmith Belt". All the circled dimensions should be measurable from within t...

Re: Mark V Speed Control

I discover that RPM is an old and much-discussed topic on this forum (https://forum.shopsmith.com/viewtopic.php?t=7538), with many of the same participants then as now. No resolution to the mystery. Last week I too went out and bought the Harbor Freight tach http://www.harborfreight.com/digital-ph ....

Re: Mark V Speed Control

Latest speed table and graph. This one shows what happens when belt length is measured along different locations - along belt inside, outside, and centroid. Same belt, but we get different lengths and different calculated speeds. As before, all the curves cross at 2156 RPM, which is at 1:1 sheave ra...

Re: Mark V Speed Control

Belt pitch length = belt outside length - (belt thickness X 3.14). The actual belt thickness (not belt width) comes into play. So for example if anyone has a belt with a 27" outside length and a 5/16" thickness, the pitch length of that belt is 26". Traditionally the "centroid&qu...
