    Feeling that the 20 odd outstanding projects I have waiting on my time at the moment wasn't enough. And that I needed something else to tuck into another corner of the workshop and cast furtive guilty glances at once in a I while. I jump on a cheap lathe.

    This Colchester Master 2500 came up on Facebook marketplace on Sunday within 20 miles of home for £450.

    I felt I could easily part it out for a profit so jumped in with both feet and bought it blind.
    Collected it today:

    Powered it yet? If so how does the headstock sound? If it is good then that is a bargain.

    It's fairly grungy and will need a strip down and clean.
    The bed has some wear as the carriage is fairy tight at the tailstock end.
    I pulled the cross slide gib and it has some wear, I think mainly from lack of lubrication.
    Drive train looks in good order and the spindle is free and smooth.

    I've not powered it up yet, but I pulled the headstock cover and the gearbox looks very clean and in good condition.
    Just rotating the spindle by hand causes gear oil to fling off the gears so it's clearly stayed lubricated.
    I can't see any damaged teeth or chips at the bottom either.

    I'll power it up before I delve in to deep but both the CNC's are running at the moment so I would hear anything anyway.

    Mine looked good as well but loads of bearing shot (not spindle ones thankfully) shafts worn but all gear teeth looked fine. I did however find a tooth in the bottome when I stripped it to replace the bearings and get the shaft hard chromed and ground. I looked again at the gears and definitely no teeth missing so I sighed with relief, that was until I rebuilt and the bleeding noise was still there :D Someone must have replaced some gears prior to me getting it and then punted it on to the farmer whom I bought it from. He didn't have 3 phase where it was stored so I couldn't test it, I think that may have been deliberate as I know farmers well ;)

    Anyway hopefully yours is a good one, if not then you could always fit a servo instead :D

    Looks pretty good in there though looking at the lube well for the rear spindle bearing it could do with a right good flush out and new oil.

    If the headstock is good then I will probably completely rebuild this lathe (at some point) from the ground up.
    If the headstock is bad I might convert the lathe to CNC and do as Hood has or sell it for parts.

    Fingers crossed it's good in there, hopefully tomorrow I will find time to power it up.

    Mine is still a manual, just a servo spindle motor driving direct to the spindle and missing out the headstock gears. The gearbox etc is still driven via the servo.

    Have the same lathe and might need spindle bearings.

    I could be wrong but I think there was somebody on here looking for parts for one of these, maybe a tailstock. :dontknow:

    Think I have been very lucky with this lathe guys.
    I ran it up today to take a listen to the gearbox. It runs like a top.
    Very quiet and smooth (see vids).

    I actually think it may just be in the first stage of the gearing in my headstock that the noise is coming from, might even be the wee single gear next to the clutch or possibly the clutch gears themselves. I have often toyed withthe idea of somehow fitting a chain drive internally to miss out the clutch and drive via

    Ha ha like how you have the leadscrew engaged in the last vid, planning on doing some manual threading to a should at that rpm? :D

    Certainly sounds good, slightly quieter than mine.

    Wow what a bargain.
    Don't feel so bad now about selling my Triumph 2000 for £600 a few years ago when I just didn't have the space. Looks like some bargains still out there.
