Having grown up in Huntsville Ala the whole existence of Marshal Space Flight Center (and von Braun) being located there is due to Army's Redstone Arsenal established there years prior. To this day all kinds of vintage electronics can be had there (if one knows where/who to look/ask). I picked...

Personally I'd avoid a Heil-coil, bet is that you could go the next higher size thread (eng or metric) that would allow a minor thread dia just large enough to drill out most the previous threads. Ex. If stripped thd is a 1/4-20 the drill size for helicoil is 17/64 (.266). I hate heli-coils...

OK: Without adjusting the motor pulley nor mis-aligning the 2 primary gang (4ea) pulleys. (save that for another day). And counting up with the two gang pulleys (shieve #1 at bottom, #4 at top) RPM Results: Note rated 1725rpm motor measured 1680rpm (2% error) With motor drive belt at shieve #1...

Thanks, I appreciate that !

One last detail: Using an old 'old school' revolution counter and a stop watch to determine the approximate RPMs achieved with all the possible belt/pulley configurations. Results soon:

With a rare optional Craftsman collet arbor #24672 & a Cross-Axis vise I should be able to achieve some simple milling in a pinch.

Used a 3'x2' piece of 3/4" plywood and drilled thru the steel/formica table top for (3) 5/16"-18 mounting bolts. Regretted popping holes thru my nice table, but rather not do a dangerous 'wobble dance' with it one day. She came out real nice, ... I'm happy. The 'decal' is just an extra touch...

This Atlas has the 3-pulley, 2-belt option with a Congress VP325X062KW, Variable Pitch Pulley on the Motor shaft. The optional part number for mid-pulley mount is 121-1. Noticed that with this setup the 50-54X motor base and the motor bracket need to be upside down to get required alignment...

After a long delay. Time to assemble & finish this Atlas 1010 restoration. Grease'em up !

Recommended SFM is material dependent and calculated for radial tangential swing of tool cutting edge under 'ideal conditions' such as tool/part piece rigidity. Variations are usually proportional/factored for other conditions; Tool material/condition (carbide, HSS, coating etc), 'rake' and...

Made a mold of rotten/decayed front emblem ,with some mods to an improved mold re-casted in red rubber/vinyl..... sure came out nicely Also more discovery... realized I actually had a full Atlas Mortise attachment set And some sweet items; vises, new chucks and especially a collet attachment

The motor is somewhat of an unknown at this point. I could not find any tech info on this GE 1/2 HP single phase with centrifugal switch control of starer windings (no caps) Also with sleeve style bearings. Initially I was very concerned with the excessive end play (.100) upon assembly. But...

The quill and pinion were in great shape, The two spindle bearings were acceptable in terms of wear but needed through greasing. After moving the bearings enough on the spindle shaft to clear the bearings out of the outside housing journals: I was able to remove the thin split spring steel...

The wear (working and contact) surfaces were left unpainted and lapped in with a large Carbonium dual grit stone and throughly oiled

80% of the work involved was removing old paint, rust and paint-prep. Nearly burned up my rechargeable hand drill removing pint with stiff wire brush. Kerosene, rinse, hot dawn bath, rinse, isopropyl alcohol rinse with final acetone wipe. Rustoleum primer with 2 topcoats of Coastal Grey. Baked...
