Boxford lathe details

First have a look on

From this page have a look through the archives and try to determine what model you have.

I would guess a BUD.

But have a look at the write up on

Generally you should be able to use a set of gear wheels on the drive between the Spindle and lead screw to either select feed or for screw cutting.

Hi,

Thanks for that.

I have just has a look. It looks like a CUD (No cross-slide feed, unless I am missing something...)

There is a gear chart on the outside of the gearbox case for screwcutting. (yay). Looks like I can do screwcutting after all, though maybe not... I only have the gears that was in the machine. Might have to buy some more then. I will have to keep my eyes on Ebay. My machine is an english version (8TPI) but metric dials (on the cross-slide) but no dial on the main slide (is this normal?)

the picture of the CUD though is slightly different from mine. I have a lever on the top of the lathe that swaps between low and high speed.

I just bought an off-hand grinder from Aldi (the supermarket chain) for £12. Should be able to sharpen my cutting tools up now... (They have a sawing tool that may be useful to the home workshop, though I don't know if it will cut metal.)

Best regards, Dave Colliver.

Hi,

I think the one with the backgear lever on the top is a mkIII, note that this has a microswitch inside operated by the socket cap screw on the toe of the lever. The screw has to be screwed in or the machine won't go! Stops operating the lever when under power which could be interesting.

Hope this helps.

Regards

What else did you expect from Troll the unfriendly.

Carbide tools from their geometry tend to generate high pressure at the cutting edge thus would tend to push the saddle away leaving you with a 'cone'. Personally on a small machine like a Boxford I would tend to use HSS tools with a good top rake this will give you a 'soft cutting' or greatly reduced cutting pressure. Having said that the latest disposable tips are tending towards a 'soft cut' so forgive me if you are using one of these.

Cannot help with that one

Hi

Well, I eventually got my power restored in my workshop (after my neighbour cut through it) though I have had to pay for it.

Anyway...

I have started to use it. Just a little bit of scrap bar I have found that I can play with.

First thing I noticed, my main slide (such a long time ago since I was an apprentice, I can't remember what it is called!!!) was sliding backwards. I was facing off and ended up with a cone. (The tool was about center height, though the center I have is a bit rough) I was using a carbide tool.

Then, after a couple of minutes use, I found that the lathe was making a rattling/racheting noise from the headstock.

I have had a look but can't see anything.

I have it set to the 850 speed setting. When I use the lever on the top of the lathe to make it slower, I don't get the rattling.

Any ideas. It appears to be a Boxford CUD.

Best regards, Dave Colliver.

Perhaps a .....NT rather than a .....D?

Now, what did I do to deserve that.

Thanks.

Answers inline...

As a new member, a bit of time to become troll bait...

When I was in engineering, I specialised in tool and cutter grinding. It is amazing how much I have forgotten.

No, the tool was a brazed tip.

After more investigation, I have found the problem, but not sure how to fix it... Maybe another boxford user may be able to help.

Under the top cover on the headstock, where the belt fastens to the pulley that drives the chuck, also on the same bar as the pulley is a large gear (towards the chuck). This gear will move towards the chuck when the low speed is selected.

From the pulley to this gear are some small dowel pins that locate into the gear when the lathe is in high speed mode. For some reason, the gear is slipping off these pins.

Any ideas?

Also, what do about maintenance of this lathe? What oil do I put into/on it and where?

Thanks. Best regards, Dave Colliver.

Did you interpret a reference to your lathe and your frustrations with it as an attack on you?

Have you a sense-of-humour failure?
