After you re trammed it you commented that you measured some out of round due to distortion. Are you sure it wasn't reading the result of tramming and raising the table ?
Good point! If I remember correctly, however, I think I measured before machining at the new setting. The table was raised by a lot more than the out of round. Thanks for your interest.
It looks like you are already planning to do what I was going to suggest, leave the support bar free to slide in the machine, grip the bottom of the arm in the vice, and use the Y feed to slide the bar through the machine to feed past the boring bar? This is a somewhat simpler operation on my mill, as it has a doevetail support bar, and so doesn't need to be prevented from rotating.
You may have anticipated my next move! However, before I can do that I will need to make the cotter and test that the setup doesn't bind. I hope the rotational issue won't be a problem.
Absolute great I like your explanations and with the shown metric dimensions it's much better to keep up without all time calculating to real numbers 😂. Just kidding for me it's great anyway.
Very beautiful old machine. I truly love the sketchwork and the analysis, and the machining technique! I am starting an arbor support for my 1941 Van Norman, and you’ve given me some very good ideas. Thanks!
Thank you! I looked up your Van Norman mill on the Lathes.co.uk archive and notice they are appealing for photos of these machines - only one small machine is currently featured and that doesn't appear to have a way of including arbour support. Interesting!
What a beautiful machine.
Yes, I am very happy without. Just about the right size too for my workshop.
I personally enjoy your drawings, and calculations
I as well!
Thanks, both, for the feedback!

That's a very interesting part to machine. With a lot of challenges. Nice one.
Just a little way further to go without 'Bozo' showing up!
Absolutely superb. What a fit you achieved. I very much enjoyed the calculations and the sketches.
Thanks, Carl!

Will try to keep including metrics equivalents. For calculations the SI system is, in my opinion, much better!
Theoretical deep knowledge combined with superb practical skills! I am utterly impressed👍
Thanks for your feedback.

very nice - progress !!
Thank you!
The stress was begining to get to me! I should have known better! Good work!!

Good one 😂! The T slotted top slide for your Colchester was a good find. Hoping to ship mine back to the UK.
love your drawings and precision work, akways a joy to watch, thank you.
Thank you very much!
Great work...
Thank you!
Perfect fit!
Thanks, but should have reached the final size in fewer cuts!
I really enjoyed this video. A nice mix of machining, lovely drawings and stress calcs. Nicely explained.
Thanks for your feedback and interest!
Very satisfying work. I'm also impressed with what appears to be a high quality of casting.
Yes, the casting came out very well - dimensionally, without hard spots or porosity. Wish the foundry was nearer!
