Re: My latest lathe acquisition , Hardinge HLVH!!

... My Hardinge is an American built in Elvira New York HLVH model. ... It may just be a typo when you copied it or it may be a misspelling in the records but 'Elvira' probably should be 'Elmira'. Google does not know any Elvira town in NY but Elmira is a well know old industrial town. It is locate...

Re: Oil leak at spindle on my lathe

Mine is a 3-in-1 machine and it leaks oil out of both ends of the lathe spindle. I sure there must be a way to take the spindle apart and repair the seals, but I just put a paper towel where it drips and add more oil when it it too low in the sight gauge. I suspect the mill head has a similar seal w...

Re: MACHINE SWITCH

I had to hook up a large VFD (350 hp) for a snowmaking pump that was needed immediately. On the control terminal strip there was a low voltage out and on-off low voltage in. I put in a short piece of conduit, a normal house type wall switch and box, stuffed a pair of wires through it and hooked up. ...

Re: Situating Fixed Tools in New Shop

Dementia is a strange thing. He is still a safe driver, which is odd, but he can only make short trips. Last year he took off for the dentist with a Mapquest printout, and he was gone for about four and a half hours. Of course, he had been to the same dentist many times in the past. I started calli...

Re: OT: Building in isolated location

On our mountain in VT there are always bears. They mostly have a route and if left undisturbed will pretty much remain out of sight. They are however noticed when they turn the garbage cans upside down and then throw the empty can down the road. A lot of people have a dog(s) and the dogs will alert ...

Re: Little Guy Wins.

The first page is interesting,if barely readable in the enlarged version. Since the second page is not enlargeable and I can't read it, I have no idea if its interesting. I don't know what people do to post unreadable things but when its done it ought to be deleted.

Re: Getting Bearing out of Electric Motor head

The spring and bearing are out...... I had found that I could with a pin/hook rotate the spring so the gap was aligned anywhere but I could not get a hook under the spring. But triggered from the suggestion about cutting the spring (that would not have worked as it was needed to reassemble the motor...

Re: OT: Building in isolated location

After spending years watching news stories of houses being destroyed by tornadoes, hurricanes, forest and household fires, earthquakes and avalanches I've often wondered why we do not have a house design that is based upon a central safe room. Most of the cost of building a house seems to be in kitc...

Re: Getting Bearing out of Electric Motor head

Use a Dremal with a small diameter grinding tip. Slot the housing and cit through the ring opposite of the split in the ring. Take the two pieces out after grinding in two. Leaves a groove in housing, but it shouldn't hurt anything. Are you cutting from the exterior side of the motor head? Cutting ...

Getting Bearing out of Electric Motor head

I am having to rebuild 4 or 5 motors after my shop flooded a few years back. They initially worked but then were idle while I moved and that seems to have caused them to set up. Motors that were submerged but then were run for 30 minutes seemed to survive. But those that were never submerged but clo...

Re: OT: Building in isolated location

Having owned a ski area with lots of buried power lines, some snowmaking guns require 480V 3P, I can attest to the need for non sharp fill around the line but at only 2' deep I really suggest conduit. Anytime I had to dig and repair a line I tried to afford enough conduit to armor the section before...

Re: Safe to Grind Tungsten on Bench Grinder?

Thorium has a half-life of 14 billion years. The activity level is too low to matter. Not necessarily. It depends upon the type of decay. If it's alpha decay, it won't penetrate paper (or your skin.) But, if you breathe the dust, alpha radiation will readily penetrate the cell membrane. This what m...
