Re: Spindle bearing replacement

The gist I got was he wanted to see if someone with the same model lathe was getting the same runout
he was getting on his based on how he measured his.

Re: Spindle bearing replacement

You are measuring the vector sum of spindle runout, collet runout, and gauge pin runout. Because you are measuring 1" out part of what see may also be due to misalignment of the headstock and/or crookedness of the collet and/or pin. Measure the spindle runout by placing the ball of the DTI probe di...

Curtis, John, Thanks for the advice, that calculator is handy,
I don't think there's any chance that the conduit will fill with water.

Re: Spindle bearing replacement

Wolfgang, I decided to check the runout on the collet sizes you mentioned. I didn't know gage pins were that inexpensive by the piece from McMaster. so I ordered two sizes, I have some precision ground .25 dowel pins so I used those instead of ordering one. . Runout was checked with the lathe cold a...

How many amps do you think you will need to see at the end of the run?
20 amps max. for just the welder if I'm reading rating plate on the MP210 welder correctly.

Re: marking tools

This is probably not going to take 10 min per tool - anodizing or black oxide treat a band on the tools.
Maybe gun bluing ? None of the suggestions are going to be high visibility.

As earlgo said, "just realize the tools will walk", especially in a student environment.

Thanks for steering back on topic, direct burial wouldn't be possible since I would have to break up concrete pavement in the tiny alley separating the outside kitchen wall to the back wall of the garage, something I rather not do.There's an existing pipe that runs into the crawlspace under the kitc...

Re: Spindle bearing replacement

Wolfgang, I have two sets of L20 collets that came with my V10P and Maximat 7, both sets are Schaublin that American Edelstaal offered as an accessory for the Emco lathes. The Maximat 7's were in near mint condition in a fitted Edelstaal wood box, unfortunately the V10P set came loose in a cardboard...

Re: Spindle bearing replacement

Interesting thread since I'm also a V10P owner. I think you should rule out everything else before you suspect the spindle bearings, it's also a 40 plus year old machine parts get scarce, bearings go out of style. Unless you bought the V10P new there's not telling what the past usage was like. If yo...

Re: Shared air and electric line

WOW, when you said castle I thought it was a metaphor for just a plain old house.
It's very impressive, maybe we should call you your Ex- Grace since you no longer own it.
;)

I guess if I don't allow building inspectors in I could run an air line in tandem with electric.
