My Clausing 100 mk 3 Serial# 5396

Another update... Installed the countershaft/cover using ball bearings instead of bushings so lathe assemble is finished. Will need to level/adjust/align the lathe when it gets mounted back on the cabinet.

Started work on the cabinet. Plugging unused holes, weld some more steel in to stiffen it. Will then paint it.

Plan to replace two light bulbs with LED and use a push button light switch to turn on when door is opened.

How many people actual bolt down/anchor their light lathe to the floor?

The lathe is currently bolted to two wood runners. Thinking setting cabinet on rubber stall mats.

Only those who spent time aligning it and want it to not need realignment any time soon.

That very question was asked in this forum recently.. All the replies said no, no-one could say they bolted their mill or lathe to the floor. But many others have their opinion as well.
 
I used to have a lot of vibration when turning with carbides since doubling the rpms. Finally isolated to the old rubber v belts - replaced with link belts - what a difference. Next step was going to anchor the lathe to the floor.

I notice that also most home shops usually have everything on casters or bolt to pallets. With the cabinet with storing all tooling inside, it is very heavy. I would say the tooling was 2 to 3 times the weight of the cabinet Made of 1/8” sheeting.

I have no problem anchoring the cabinet to the concrete floor but after 15 years in my shop still relocating equipment.
 
Contacted Tom McNett at Clausing to see for availability or drawings - no longer available and no drawings:

DL-281-S Motor Dual Pulley (1-3/4" & 5") 5/8" Bore

Q-536 Gear Train Cover

These two items are not show stoppers.

For the Dual pulley, can stack two single-groove cast iron pulleys back to back.

If any one has the lathe with the QCGB and could traceout/draw dimensions of the cover would save some time. What to make a replica as close as the original by welding/grind steel together.

Your idea as to how to fix the cover problem is probably doable. However, two single step pulleys will be much too long. I believe that the availability of Atlas parts is much better than the equivalent Clausing parts. The 10-428 Motor pulley is a little smaller than what you quoted at 1.930" and 4.390". The distance between grooves is 0.625". And to get the belt to fit properly in both grooves would probably require changing both two-step pulleys. The 2-step countershaft pulley 9-427 diameters are roughly 7.5" and 9". And the ID is 0.750".
 
Thanks Robert for the heads up on the Atlas pulleys.

It is possible to turn a new pulley but probable needs to be balanced. Would the pulley dimension be based on pulley OD or inside ID of the belt?

Here are the two motors side by side. Still a lot of work To do on the cabinet.

Light Duty or Fractional Horse Power (FHP) and Multiple V-Belt belts are both specified by the length or circumference of the outside of the belt, not the inside. Machinery's Handbook gives the recommended pulley groove dimensions. The angle specified as between the two sides of the "V" or between the radial plane and either side of the "V" varies directly with the pulley OD, running between 30 and 38 degrees or between 15 and 19 degrees.

I'd gladly help out if I can, But I cannot picture which cover you're after.
 
Here it is... Yeah I could fab this total from scratch with trial and error fitting it. But having some basic dimension would help.
This is on a low priority right now.
