Razzie,
Yes I have drawings, but only for a few selected parts. See below. Do any of these help you?
Yes on the logan lathes group.
My dimensioned drawings are currently hand-drawn sketches in my shop notebook, not CAD drawings, and are limited to a handful of specific parts.
I suppose I could take pictures of the notebook pages and post them.
Caveat: all my drawings are from a 1944-vintage Logan 820 that has many heavily worn parts. My measurements are my best efforts, primarily using Harbor Freight and LittleMachineShop supplied tools.
Here is a list of dimensioned Logan 820 drawings in my notebook, with my page number, and the Logan part numbers (for my version, s/n 24157).
1. Apron Handwheel shaft, p. 38, (LA-549)
2. Cross-slide shaft, p. 40, (LA-153)
3. Acme nut for cross-slide shaft, p. 41, (LA-173-1)
4. Compound-slide screw, p 41, (LA-152)
5. QCGB slider shaft, (LA-472)
6. QCGB Main shaft, (LA-470)
For numbers 1, 5, and 6, I created my own parts. I hesitate to try #2, 3, & 4.
I have been trying to get adequate proficiency with some CAD software and have tried and failed with many packages. For a few years now, I've looked to master AutoDesk's Fusion 360, and struggle with my lack of 3D modelling experience and the software's lack of comprehensive documentation.
But I'm getting there and just this week modeled some Logan parts for another forum member. These were the brackets/bushings/thrust washers used to mount the worm on the rear of the apron. For some reason, they don't seem to be in the Logan parts catalog. I have these in .pdf, .dwg, and .f3d format.
