Thanks all.

i spent more time with today and made some progress.

Feeds are now working thanks to wd40 and some wiggling.

I removed the lower gearbox cover - there is damage to teeth on some of the gears. This will account for some noise. I don't know how worried to be about this - I've not looked inside the screwcutting gearbox on a lathe before but assume that some damage is not uncommon, particularly on hobby / training type machines. I put it back together and it's certainly quieter with fresh oil in.

One stupid question - do the micrometer scales on the handwheels move independently of the wheel on this model machine - mine don't but could well be rusted together presently???

The lathe has had the suds pump removed - there is nothing at all in terms of coolant system. I would like to reinstate this.

I ran the lathe and it seems ok at the 2nd highest speed setting - I assume this corresponds to 510 or 1020 but this would have been with the original 2 speed motor - seems quite slow to me so more like 510 or less. If I run it on the highest setting it runs for a while and then cuts out for a minute or so until the click and then it will run again.

Also the lathe only appears to run in the standard ccw direction - is this due to the single phase motor? can a single phase motor be configured to go both ways?

I also noticed that a significant part is missing! The lower changewheel has nothing holding it on! I have a copy of the manual and parts manual and it should have a knurled nut - 30579-1, collar 30566, washer 30606. the nut is an odd thread (3/4 OD, 20tpi). Does anyone know where I can buy these items?

I looked at the motor - the plate was pretty worn but looks like:

Frigidaire p/n 5496279

Crompton Parkinson

1/2kw, 230/250V, 50 hz, 8 cos theta

I couldn't read the rest.

Murray - bearing in mind that I am starting from scratch with the coolant system, would you still recommend 3-phase/VFD or stick with what I have an look for an aftermarket 240v coolant system?

Cheers!

Hi All,

I'm hoping to find some info about a Colchester Bantam I picked up today. I paid the grand sum of £300 for the Bantam - it's been sat in someone's shed for years and gathered a significant layer of surface rust.

I got it home and managed with plenty of bed cleaning and WD40 to free off the x & y axes. I removed the cover at the top of the machine and the gearbox looks like new.

The machine has a 240v single phase motor so I connected it up and gave it a go and it runs but does a few strange things. I understand that this would have originally been 3-phase but I don't know what compromises are now in place due to the single phase conversion. To start the spindle I turned a lever which is on the center or the cabinet. It runs for a bit and then stops - it then won't restart until something electric clicks - this takes a minute or so. Does anyone know what this night be?

The lathe sounds ok but when the power feed is selected and the "bar" is rotating it is quote noisy - is there any reason for this? I also can't get the power feed lever to select on the apron - seems like it is stuck in the off position.

I definitely need to buy a couple of bits - the plaque with the screwcutting information is not readable - are these available anywhere? I also need the tailstock handwheel. Any ideas where to get these?

Any help with this machine is greatly appreciated.

Thanks,

Matt
