Thread: Lathe

Does anyone know where I might find Boxford lathe parts? I picked up an old 9inch one in pretty good nik with the intention of getting into some hobby machining, although it's new to me as my school never had metal work. Any way I noticed one of the gears in the head is missing 2 teeth. It doesn't jump but I guess it's loading up the tooth behind it rather than load sharing. I think it's a back gear and has what appears to be 2 share pins in it. Obviously they didn't do what they are sposed too. Before I try to get it built up and hardened I was hoping to find a replacement. I understand these are the ones that schools used to use so hopefully fairly common?

Thanks. Will keep an eye out

Mimms2. You obviously haven't seen my welding!lol . Would only attempt if I had a spare before I made it beyond fixable
PaulNZ. I have asked the trademe man and waiting to hear back. Not knowing much about lathes and engineering full stop. My description may not be accurate. This gear is held by those pins against the drive pully. You move a second shaft with two more gears on a cam shaft over with a lever to engage this and or another gear. What makes me think they are share pins is they are not solid but hollow and you can see small splits on one end of each as though they almost shared off but I'm guessing a tooth was lost first. But as I say just a guess. Yes that UK site looks promising if I can't sort it locally.

Thanks guys

Yes not a big gear and welder mate is screwing nose up, but will step up if I can't get another( he just doesn't know it yet) Want to do a bit of thread cutting so slow stuff ups cause less problems than fast.
Not like any roll pins I've seen. The half that sits in the pully part has no splits yet the other half has 2 or 3 that look stress related. Not the usual full length split on standard pins. Also very lite weight. Or are these special ones used in a lathe?

Drive pins on mine are definitely not hollow for what it's worth- I just checked. Mimms - min speed without backgear is 210rpm. Not saying it can't be done, but I appreciate the backgear on mine when threading to a shoulder! Also nice to drop the speed when parting tough material sometimes.

Edit: I should say not hollow on the front face. They may have blind hole in the back where the compression spring sits - I can't remember without pulling them out.

I have a full set of gears for a Herbert, Aussie lathe, were they a knock of the Boxford? I don't know, but maybe a gear that fits?

Jeeze, minimum speed on mine is 37 rpm

Have talked to a local gunsmith and he's going to look at the gear for me and see what can be done. Probably get him to cut the acme threads on the screw brass nuts as well since they are pretty worn with a lot of back lash. I did manage to make the new brass nuts as my first project which kept me busy for hrs watching google clips an putting into practice what id seen.
