New Lathe and Chuck

I finally got my Precision Matthews PM1030V and Spindle mounted Chuck from Trent Rudat. I like the spindle mount clamped in the 3 jaw chuck. It will make changing out fast and simple.

How bad is the runout with the spindle so far from the headstock? The faceplate that Trent made for me lets me close the jaws right at the shoulder of the faceplate.

A 420 pound lathe on that bench is too much, I think. All manner of warp-related shift/drift/twist/level problems will develop over time from the weight and vibration.

Wood can be successfully used to support machinery in non-commercial environments, but it must be adequate to the task. A piece of 3/4" ply held up at one corner by a 2x4 (which anymore is actually 1 and 7/16" by 3 and 3/8"), isn't, though. (Indeed, it could literally be unsafe depending on the individual 2x4. They are not created equal.)

Personally I would want to shorten that arbour. With it hanging out like that if you get a crash or a bad catch then you could do some read damage to the headstock or bearings.
Personally I prefer a direct mount chuck (all mine are) for accuracy and safety, I realise that isn't always practical but reducing the arbour will help a lot in your case.

I am planning on shortening the spindle. I just received the lathe and chuck and put it together for a photo. I haven't checked it with my dial indicator yet, so I don't know how much runout I have to deal with. If it is excessive, I will direct mount it.
I plan to move into a much bigger shop in about two years, and then I'll have plenty of floor space for the lathe(lathes).

Sweet! That's a fine piece of machinery.
