Re: 40 HP Phase Converter Question

Mike, I never seen a 30hp motor running on a phase converter. I think this boy needs real three phase power. Also, check out the current rating, I'll bet ya it will pop your main breaker even if you get the phase converter you need. I would suggest utilizing a smaller motor unless you need to take 1...

Re: Ideas for mounting a chuck to a rotary table

For a quick but not as strudy or accurite setup I made this adaptor to take my three jaw directly from the lathe to the milling machine. It has a 1-1/2" 8tpi thread ( Southbend) and an MT2 taper. Made it from 2" diameter 4130.

Re: Turning cubes on a faceplate

Re: Toolroom vs. Engine Lathe

Toolroom lathes are of smaller capacity but are extremley precise. Examples are the Hardinge HLV, Monarch 10EE, etc. Engine lathes are more common and are built in much larger sizes as well. If you. as most hobby people, don't require sub .001" precsion, the engine lathes are generally much less exp...

Re: Lubrication of a '68 SB Heavy 10

I have a 1968 SB 10K and I also have the factory lubrication chart. Southbend used to sell the oil themselves. They had a light and a medium oil. The light viscosity oil was used for the spindle bearings and apron clutch. The medium oil is for all other points. The back- gear shaft is lubed with a t...

Re: Help needed on rotary phase converter/transformer

You gave ratings in OHMS for capacitors, that is a measurement of resistance. What is thier ratings in microfarads? Perhaps they are not correct for your application

Re: Opinions on small knee mill / Clausing 8520?

I have an Enco 5100 which is similar to the Grizzly you mentioned. It works Ok for it's size, but the spindle to table distance sucks and becomes a major drawback to these size machines. After mounting an vise and a tool in the R8 collet, you have precious little room for the workpiece. Forget about...

Re: Plastic Stock

Delrin machines really well, but is not inexpensive. HDPE ( high density polyethelyne) mahines just as well and is less costly. It does not have the tempreture range of delrin, but that is not an issue in your case. I have purchased both in sheet and rod form.
