Now...off to Home Depot to get the items needed to make the bases for the machines.Initially I was going to mount the machines to my lab workbench but I didn't like the idea of drilling holes in the bench and it would set a terrible precedent if I needed to move the machines.It is also true (as mentioned in the documentation) that mounting directly to the workbench will amplify motor noise and vibration.With a machine on a base with rubber feet, I'll be able to move the machines around.I'm limited to a 5' long workbench and this will allow me to move the machines around as I need them.Hopefully they won't walk on their own.
Thanks all.I'll work on the QCTP a little later.I got the bases built and installed. I used a white shelf from Home Depot. It's covered in some kind of plastic so I don't know if painting is needed at this point.They're a huge improvement in stability and noise but I notice the mill vibrates a bit. I don't know if that will be a problem.(Be sure to drill from the top side. The board tears a bit when the drill bit gets through.)Went through Hugh's thread. Lots of neat ideas there.Thanks Marv. I like the idea of putting a plate behind the lathe. That's another to-do.Concentrating on the lathe for now...Reviewing all the various adjustments (backlash, etc.) and alignments.I should be able to cut some metal in a day or two. Probably just face and turn a bit of rod and try some drilling and parting.
A smaller issue is the brass round nut at the end of the lead screw that goes against the saddle. It's rotation is prevented by a 'knurled' similar round nut next to it.See attached picture.I can't get that round nut to seat against the saddle.
Zee:I don't think you want the brass round nut to seat against the frame. It is for backlash adjustment, you loosen the screw holding the meshing brass round to be able to turn the round nut. Once the backlash is taken out by rotating nut till "snug" tighten the screw to hold both in position. If the round nut were able to seat against the frame it would mean you're out of adjustment. See the Sherline directions.Quote from: zeeprogrammer on February 09, 2020, 07:50:50 PMA smaller issue is the brass round nut at the end of the lead screw that goes against the saddle.

First though I need to rearrange the shop. I want to figure out a way to have all my machines in the back of the shop, arranged in a way to minimize swarf everywhere. I'm trying to get a 4x8 table in hoped of building a small railroad (I have grandchildren! Yeah.)
Actually it should be against the frame - it has a stepped back that fits into the hole, and should be all the way in. Adjusting the handwheel should push it back in all the way.
Crueby:I'm wrong, and you're right. I though the nut was threaded into the frame but it's a slip fit on the outer OD. So its shoulder has to go up against the frame to work against the main nut and reduce backlash.Thanks.Quote from: crueby on February 09, 2020, 10:27:37 PMActually it should be against the frame - it has a stepped back that fits into the hole, and should be all the way in.

No problem - I only know since I had to replace the one on my lathe last year, finally wore it out!
