I have always avoided the change gears on my lathe. It is just a pain to do for a lathe that really does not get alot of use but is very useful when i need it. I have always wanted to install a QCGB on it. This is my thread to do so.
The game plan is:
- Research, research, research.
I have yet to find this conversion done but i have read a few items in adapting QCGB's to larger Logans.
- Locate a suitable gearbox.
From a 9B if possible but rumor has it that the 10" and 11" Logan's are the same.
- Figure out what, if anything needs to change or be added for the adaptation.
I do not expect it to just bolt up.
- Get-er-done.
I have owned my Logan 400 for about 20 years. (The logan 400 is a 9", short bed lathe. It is VERY similar to the Logan 1400 and 9B) It was made in the late 40's. My Grandfather bought it in the 50's or 60's from a VW shop that used it to turn brake drums. It was passed down to me.
Over the last 6 weeks i have undertaken a full restoration of the lathe once i found that the headstock bearings were shot. That project can be seen here.

The restoration is not yet complete but i am too the point where i am slowing down as i wait for the last few bits to arrive.
In all honesty, i am already nearly complete with the first step and i have already located and secured the a QCGB from a 9B. However, for posterity and to help the next guy who wants to do this i will step thru each part with what i have learned and done. I believe this thread would also be helpful for anyone with a larger or different model Logan who wants to do the same.
