I think it looks just as good fabricated and machined. Looking good in general! :thumbup: :clap:

Getting on with the collar which required a few dubious setups on the lathe (my homemade milling machine is not really man enough for the jobs) I think I am going to take some more material off the back so I can use my slittling saw. As you can see in the second pic I can remove about 8mm.

I am moving on to the motor and spindle now and if I had planned ahead I could have saved a little work because it can be used pretty much anywhere and I could have used it for making the helical groove on the upright. However I decided I am going to use the motor and spindle (with some mods) from my toolpost milling attachment. For this I am going relatively close to the plans in the quorn book, I have purchased the angular contact bearings and am even copying the labyrinth seal arrangment. I ground a cheap boring bar to make the trepanning tool, I have included an image but it's not brilliant. In the next image you can see why I needed a right angle trepanning tool and the results of it and the final image is just the modified spindle body.

Trying to follow here shipto, but admit I'm not quite sure what photos 2 and 3 are of. Photo 1 is a tool bit for sure. Well 3 looks like a spindle housing, not sure if the trepanning tool was used on the outside top and bottom... guessing so. I imagine the inside was done with a boring bar.
Photo 2 --- is the spinning shaft and blued arm the trepanning tool itself? Does the tool bit go in the threaded hole? Are they being driven by the chuck? What are they working on?

Sorry was part way through posting and my mate turned up for a coffee so lost my thread a bit. :lol:
Pic2 is indeed the shaft turning between centres and the blued bit is the drive dog I made to turn it. The trepanning tool was used to cut the recess close to the drive dog and the threaded hole has a 10mm bolt sticking out of the back being pushed around by one of the jaws of the chuck.
Pic3 just shows the modified spindle body which was used in my toolpost milling attachment (different thread).
