Setting Up My PM935 Mill

Do you have the part number and brand for the cylinder you used? I want to get one so I have it when my mill arrives.

Also, what is the diameter of the base? The drawing doesn't show that dimension.

Oops! Never mind. I watched your video again and you said it was 6.8" in diameter.

Thanks,
Ed

Ed, I don't have the part number for the pnuematic cylinder as I bought it from ebay based on stroke, port size and thread size.  It was a 1" stroke, 1/8" NPT threaded port, double acting (not the spring return style) and had a 3/8-24 threaded end on the rod.

You may want to check McMaster Carr's catalog and see if something fits the bill there.  When I bought from ebay there were two in the lot and one looked to be slightly used, I used one for my original design, then had a hairbrained idea of building me another one (my current setup) after watching a youtube video and seeing a different design.  I had a gentleman on garagejournal.com forum ask to purchase my original power drawbar which I sold to him as he too purchased a PM935TV recently.

I always lower the table as low as possible to making the change over to of from the rotary table, as easy as possible.

I thought about getting the power Z-axis (knee) but I already blew my budget to hell so decided against it.  It really isn't that big of a deal for the majority of the work I do.  I don't find myself having to go to either extreme much, maybe 6-8 inches in the middle or upper middle of its travel is where I spend most of my time.

I have to admit, last night I used my mill for about an hour to machine a new trailer plug mounting bracket and I am soooooo glad I built the riser stand to get it at a comfortable height. I am also glad I don't have to reach for the drawbar and especially happy to not have to stand on anything to reach the drawbar. I see that as being a safety concern or trip hazard when not being used. Another reason I dropped all my air and power for the mill from my shop ceiling as I hate cords running along the shop floor and becoming a trip hazard (besides the fact that hate the appearance of cords running everywhere). I guess that is the industrial mechanice in me and having to deal with 5S and process safety management for the past couple of decades.

Mike.
