Re: quick change gearbox questions


m. allan noah
 

You don't have a workshop lathe, you have the older, heavier, wide-bed 'Series O' 9" lathe. In the late 30's, this lathe was improved (Series R, S, T etc) and had its swing raised to make the Heavy 10 (aka 10R and 10L). My understanding (though I have not measured it), is that the location of the leadscrew was moved away from the bed during these updates, so the Heavy 10 gearbox will not work. You would need a gearbox from a similar era 9", which unfortunately looks really similar to the Heavy 10.

Periodic maintenance begets upgrades, as they do.? I've had my 1926 9" workshop(?) model B 4 foot for about eight years, and have been upgrading things as needed. I'm thinking that I might take the quick change gearbox plunge. I'm not restoring the lathe, so originality isn't a concern - only compatibility and function.

Which QC boxes fit this lathe? I think that the ones up through the 30s fit, but I'm unsure.

I looked for a cross-referance/interchange chart for the different generations & models; looked at catalogs, forums, advertisements and anything even remotely related to what parts from later lathes can be fitted to the 20s-era ones.

I never use the last foot of lathe bed, so could get by with shortening the lead screw if I can't find the appropriate one.

Any guidance is appreciated. If you have one for sale, let me know. I"m fine if it needs to be cleaned or refurbished. I enjoy doing it.

In case I'm mis-labeling my lathe, here are photos from the last time it was clean - when I built the table for it in 2017. The table is more colorful now, but too dirty & cluttered to get good photos.
