You do not need to use the DRO to use to lathe, it is quicker than the scales on the handwheels so can help to speed up positioning and general cutting operations. Although you will still need to use Micrometers and Calipers to make final accurate finishing cuts. text/html 2024-11-19T21:42:36+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.bristolhackspace.org/equipment/metalshop/metallathe/metallatheinduction?rev=1732052556&do=diff This PAGE UNDER CONSTRUCTION Harrison M250 Metal Lathe Induction Bristol Hackspace V1.0 02/05/22 Author: Drew Batchelor Edited with Alex Rowe.

It is works exactly the same as the original manufacturers dial so the [PDF of Harrison M250 Manual] can be used as a reference. There are in fact two TIDs a Green one with a 20 tooth drive cog and a Blue one with a 21 tooth drive cog. Which one you use depends on the pitch of the thread you are wanting to cut, see table below.
