Re: quick change gearbox questions

Have you considered an electronic leadscrew?

Re: quick change gearbox questions

I can tell you how I handled this situation. I sold my lathe and bought a 9A. The price I got for my old one and the price I paid for the 9A with a GCGB was a lot less than the cost of a GCGB not including the time to fit it. Plus a 9A has auto crossfeed.

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.

Model A Table Top in South New Jersey

#108172

My Uncle, who used to be on this list, passed away last year. His wife is clearing out his storage and I toured it today. I spotted this lathe, and took some pictures. It's in rough shape and the motor is not connected. Photos attached.

Here are the specs that I could glean:
Model A
Catalog No (hard to read)4-R
Bed length: 4 1/2
Serial Number: 106, 490
Additional stamp: USN Propery Cont No BS-909

I do not live near the lathe, so if there's interest, I'll get you in touch with the owner. There is a sale coming, but I don't have the date yet and I thought this group might be a better place with more interest. No price is set. Contact me directly (hillkid@... (mailto:hillkid@...)). I have a spam filter, so either follow the return instructions or text me that you emailed me at 301-928-0728.

Re: Lathe ID

Much as I would love to, transport from CA to southern MO sight unseen (except for pics) is too rich for my blood. Can someone put them up on a local Craigslist or Marketplace for him? I'd really hate to see these get scrapped, there's a lot of life left there. Heck, my own 10R ought to be scrapped just because it's swaybacked beyond repair, but I'm still using it.

I am sure he could get wine money if he took some parts off and sold them. Easy stuff, like the chuck, the tailstock, the motor, compound... nothing that require extensive effort.?

Can someone share the pics again. I can't find them anymore.?

Best Regards,

Andrei

Now that we have an idea of size and age is there anybody in the Southern Califoria or (further away) that would be interested in these lathes. Do to the age and general condition the owner is not going to restore them. What he said was he will "turn them into beer money". I don't blame him. It seems harsh but scraping them is in his best intetest.?

That first one looks a lot like my 1942 UD Heavy 10R, 199-Y. The giveaway between the 9/10K and the Heavy is that funky spindle lock handle on the tailstock, but the 11 had that as well. The dataplate should be on the gear cover on the left end. 10R was a 199 for engine, 8199 for toolroom; 187 for the 10L engine, 8187 for the 10L toolroom.

I've been told the other lathe does not have any serial numbers on the bed, does this seem likely? I'm asking for pictures to confirm.

Mike Allen asked for more info on the rear mounted tool post seen on my SB 9". This came to me with the lathe. It's an added dovetail to the cross slide. Held by four smallish cap screws it's not the world most rigid set up. In fact, I've yet to use it! These are frequently speced as useful for an inverted cutoff blade, but I have been parting from the front forever and usually don't have a problem. (I don't part off 4" diameter slugs!)?

Right now it works well as a flat spot for the cutting fluid!

Now don't ask what the three tapped holes down the middle of my half nut lever are for, I don't know! (Someone suggested they were for mounting parts for an 'automatic' disengagement mechanism.)

Hit send too quick, here's some more photos. Headstock casting photo from ebay listing, comparison of the two headstocks (note the modified quick reverse and the new stock quick reverse mounts). Last is showing new headstock with more belt clearance.?

I bought the lathe in about 1985. It sat uncleaned and unused until about ten years ago when I disassembled, cleaned and painted it. I was going to use the cast iron legs from my Enco12x36 which I built a steel bench for, but the mounting surface board I made almost perfectly fit an old desk I was breaking up for firewood. Glad I did, the desk is much more stable.

I upgraded the reverse lever using a flame cut plate for the sector. Then I had a problem changing belt speed as the four step sheaves that came with the lathe were very close to the headstock. I found a headstock that incorporated the quick reverse lever and found that it offered an extra 1/2" clearance for the sheave,

Vary nice lathe now, though I wish I had used a darker gray paint!
