Re: Greg's Logan 820 Restoration - QCGB final reassembly - part 2 of 2
And continuing the reassembly, next comes the main shaft, the one with the dozen gears. Here's where you really need the red alignment marks. In the second picture, the old shaft is inserted from the left, as an alignment aid.
Now the slider shaft and the shift arms. They go on rather easily, but still, the alignment marks do help. And this time, I do have the gears in correctly, so that the two arms/gears are mirror images of each other. I tested each of the shift arm positions, turning the gears by hand. All turn okay, a bit stiff with the brand new bushings. Note: I did soak all the bushings overnight in oil before the reassembly. I don't know if they need it or if they are factory-impregnated. I don't know if it helped, but it couldn't have hurt.
The nameplate/threads and feeds table was cleaned up by re-doing the red and black sections, then lightly scraping and sanding to clear off the raised brass characters.
Then, inserted the lead screw and reinstalled on the lathe... Hooked up the gear train, turned it over by hand, then with power.
All works fine and sounds smooth! Ready for another 70 years? I am happy

So what's next in the restoration?
- Test/measure the headstock and tail-stock alignment (I never leveled/aligned the lathe when I moved it into my shop.)
- Overhaul the tail-stock. Hopefully, this is just a cleanup and repainting
- Fabricate a set of adjustable leveling legs, using the hockey puck idea suggested by Steve back in July
- Repaint some of the other easily removable panels, such as the gear cover and the belt cover.
Then, probably in January, the big pieces. I suppose that my lathe will be out of service for a few months as I tackle the remainder.
- Counter-shaft/motor/peg leg (clean, inspect, repaint, rewire?)
- Headstock and gear train (clean, inspect, repaint, make a back-gear knob latch mechanism)
- Bed (repaint)
- Chip tray and legs (repaint, add the leveler feet)
Reassemble and level/align
Hopefully I will not discover the need for the lathe to make repair parts when I have it totally broken down. If anything is going to need some parts, I'd suspect it would be in the counter-shaft area. I will check that out first with some "exploratory surgery"
Happy Thanksgiving, Y'all,
Greg
