I guess its time for me to start my own Home shop thread.
Just out of curiosity which panels are you looking at ordering and where? I am thinking of covering my shop with solar as our electrical rates are climbing fast. Would be a similar size system. From what I can tell a DIY install right now probably has about a 5 year payback around here...- pmtool

OT: How to find hot-shot truckers?
Where in Oregon is it? Big state.... I have used pack and ship type places. Navis Pack & Ship is one. There are industrial craters as well. If you want good prices in the Pacific Northwest I would avoid companies with "rigging" in their name.- pmtool

Round bar ways machines.
From the manual and a shot showing the machines taper setting system. Pretty nice dialing in tapers or removing them when you are essentially using a 10ft long sine bar. -

Bar feeder troubles on Staar SV-20 with LNS Hydrobar 220
You can align pretty close with a tight string or fishing line. Take 2 pieces of appropriate size round bar, drill a hole through center the size of the line. Clamp one in the machine spindle and one in the barloader gripping collet. Tighten the string between them so it is taught and use the...- pmtool

Fixing Milling Arbor Runout
Really? Risk an expensive spindle to fix a cheap arbor? If they really run out as much as you say why even try to save Trying to straighten an arbor while in the machine spindle with a floor jack is a bad idea on multiple levels unless you care less about the spindle than the arbor. Why risk... -

Spot Treat or Touch Up Hardcoat Anodize?
I wonder if you could make some sort of two piece bolt together "case" or enclosure complete with oring material that would completely waterproof the part with the exception of the bore. Have each one put into the case and re anodized after you deal with the bore size. Obviously time consuming... -

Appropriate steel for vintage horizontal mill spindle?
In similar jobs where heat treatment is not an option I use 4140 pre hard. Mids 30's Rc hardness machines fine. Only a few bucks more expensive than 1018. As noted above I would fix what you have. Grind/ chrome/ grind is the industry standard process. Not happening in an average home...- pmtool

CNC retrofit woes with Machmotion
Interestingly Machmotion also does retrofits on CNC cylindrical grinders. No idea on the quality of them but not really "hobby" grade. Not sure what the motion control on them is. Yaskawa servos and drives.- pmtool

Proper bearings for a mill spindle rebuild?
Most bearing manufactures now a QR code on the bearing box and have apps that you can scan the bearing box on your phone and it will tell you it is a legit bearing. Pretty slick. Of course new old stock type bearings on ebay would not have this. I agree, unless it is a low budget personal... -

Proper bearings for a mill spindle rebuild?
One other thing to know is that the Abec grading system is not really commonly used to classify spindle bearings anymore. You will see P5, P4, P3 instead. Note it is opposite of the abec scale. Lower numbers are the better ones. P4 is essentially equal to Abec 7. P4 are used on probably... -

1981 Bridgeport Series 1 CNC
Not to be negative but you can buy a modern good condition vmc with tool changer and enclosure for way less than 20k and be miles ahead with no time invested. Fixing up old cnc mills is for people looking for a project in itself. I have been down that road a long time ago. Sad thing is...- pmtool

Taper control adjusting tailstock for Jones & Shipman cylindrical grinder
I have a Kellenberger grinder that has the ability to move the tailstock in very fine increments with what basically looks like a large micrometer dial on the back. It moves in 10 or 20 millionth increments or something like that. Total travel of only a few thousandths. Basically you use the...- pmtool
