Looking good! How much vertical travel at the spindle axis are you aiming for? Having used the original Quorn, what sort of work made you want to use that adjustment once coarse column height followed by fine initial alignment was established?

Thank you, the travel is very small and the amount of travel I have in this video is probably sufficient although I have already milled it out more for a little more travel. The course spiral on the column gets you close to center height then minor adjustment of the spindle to center height then this adjustment is used again to raise the spindle for the relief clearance

Excellent job and video as always. Appreciate all your hard work. I have a question, I'm sure has been asked so apologies if this is a double tap, the original Quorn is cast iron, however you are doing it in aluminum. Are there any concerns with rigidity vs. cast iron? I am new (

Thank you, I have no concerns at all, my original quorn is also aluminum. If the castings were highly stressed or subject to shock then it might be an issue,but none of them are. The advantage to cast iron might be the weight gain but the difference is not as big as some would have you believe, and when it’s solidly bolted to a steel plate like my original quorn or the concrete base I cast for this one they become one solid mass and is very rigid. Also bear in mind that in the early days cast iron was the standard for machine tools because it was inexpensive (and did and does work very well) so was cost effective to produce castings, where as aluminum was an exotic material at that time so it was much more expensive and used less.

@@hillsgun thank you for the thorough answer. Makes sense. I look forward to the continuation of the series.

My pleasure, quite a bit more progress so there will be more out soon. Dan.

Do you think the Quorn could be made from fabricated weldments instead of castings?

It’s been done before,although it’s usually a variation that ends up being different.
