Re: 9" motor start switch
It's back together and running fine pending the new start cap. As the failure to this motor was from oil I went on a search for the source. Those of us with a top mounted motor can stop reading now. The feed reverse assembly fits in a stepped bore that is open to the inside of the headstock. Oil from that goes through the bore and straight down onto the undermount motor. The motor fan passes the oil droplets around internally and gunked up the start switch.
To fix this issue I turned a hard rubber plug (hockey puck) to 1.060 and about 1/2" thick with a bevel on one end. Push this press fit plug into the bore with a wood dowel and hammer it into the smaller diameter 1" area of the bore until it provides enough clearance for the reverse shaft to not hit it. This will seal the hole off and any escaping oil will come out the gear end of the headstock.

I’d be interested in any tricks to get the compound locking pins to release also. Can’t get my compound off my 16” SB either. Steve Haskell

Not sure of wattage rating or type. I think I used 1/2 watt. There is plenty of info out on the net. The resistor serves to bleed down the charge on the starting capacitor.

Will try to get power to it by next week to see if it runs. Still looking it over to see what needs attention prior to running it. Is there a good source for gears? One of the gears. A 20 tooth if I recall is badly worn and will likely break of put under any serious load. Also what is the easiest way to get tge lockong pins out from inside the compound and riser blocks? I ttied rockong it around with the keepers out but thr pins wrll not loosen up and come out.

Do yourself a favor, put a 51K ohm resistor across the starting capacitor if there is not one. This will extend the life of the switch contacts.

The blackening is primarily oil and dirt that has been zapped by the contacts for 61 years. My first looks said oh boy, this thing is toast. I hit it with contact cleaner, tooth brush and 600 grit which has spiffed it up pretty well. Then some burnishing with paper and I'm going to put it back in hopefully for another 61 years. I'm feeding it a new start cap for grins. I think I'm lucky on this one as several sources have said, nope, that one's been obsolete for 30 years. I have a buddy in plant maintenance that deals with motor vendors weekly. He's checking his sources and if he finds one I'll pick it up for a spare.

Speed chart for the V-belt 9" lathes is in HTRAL (at least my 56 edition).

Call it the centrifugal switch, to avoid confusion.

Any motor such as this should have a bleed resistor across the start capacitor. This will extend the life of the centrifical switch contacts.

Re: 9" motor start switch

Most shops do not bother with smaller motors. If a new switch assembly is available, you have it made. It is always nice if you can put the original motor back. I have gotten around a problem like this by making a homemade controller. This will involve rounding up a few common parts and a bit of rewiring.

You might try to get a replacement switch https://capacitorwarehouse.com/t/electric-motor-start-switches Or rebuild the old one.

My .02c is if you have a chronic problem then sure, change the log in. But one person who put up one set of posts and is no longer of the forum probably isn’t worth changing a process that has worked quite well for a long time.

For my E-Leadscrew group I have the same conditions. Anyone can join without approval but first post is moderated. It's worked so far. It might just be that one user trying to be helpful. But I think it's inappropriate.
With Yahoo we forced a new user to tell us why they wanted to join. And we've been pretty strict about keeping posts on topic. That's not to say that discussions must only be about my ELS. In fact any electronic lead screw discussion is welcome and supported. But no drifting into political bashing or for that matter member bashing. Just not tolerated. As would be a generic link to a web site.
And I prefer people use their real name.

At the present time new members can join without any pre-approval. They must then have one approved post to have full privileges. We can change that.
