Lorch lathe

    Some of you may have seen I recently posted about needing a shaft turning and I was struggling to get it done, I thought stuff it and found this little lathe fairly locally to me and I could just squeeze the shaft in between the centres so did it myself. I have never used a lathe before although this Lorch is clearly old and fairly basic I do need some practice getting a good finish!

    When I got it the shaft the cross feed screw fits in was snapped and had been brazed badly before, no matter what I did I couldn’t get it to hold, I think it had been dropped at some point because the cross feed screw was bent which was putting pressure on it every time it was brazed. So I machined a new shaft, welded on the collar at the end and bored a 16mm hole for the screw collar to sit in, drilled a 10mm hole for it to slide through and made a new section for the other end, all from mild steel and welded together. Straightened the screw out with my big hammer and it now slides across freely and easily. I had to do all of that using the broken part and now I am finding it is much easier it is holding itself together!!

    There is a lot of backlash, the thread is clearly worn on the screws almost to a perfect point on both slides. I have a bit of a project on my hands I think and seeing as I am unable to cut threads on this machine I may need a hand from someone to turn me a couple of new feed screws. Left hand threads too.

    Anyway sorry for the rambling, I do like the lathe and it is from the time when things were made to work and look good at the same time. The front plate is off at the moment as I was just giving it a clean up to remove the years of grease and grime.

    Can anyone else give me any information on this lathe and from the photos what I need to do to get it back to how it would have been from the Lorch factory? From my research it looks more like the Lorch lathes that were rebranded and sold a Stedall lathes but there are no Stedall markings anywhere.

    So here it is

    There is a wealth of information about Lorch lathe models on the " lathes.co.uk " site. I have one which I will get around to restoring sometime in the future. Do you have a countershaft unit to drive it ?

    Not the original but this is how it is driven, 1.5hp 1ph 1425rpm brooks motor.

    It’s a bit bodge but it does the job, very smooth and quiet, only noise is the ticking of the clipper belt. I wired a switch in which I relieved from a knackered Lidl pillar drill, made a little box for it and mounted it on the bench. Much easier than bending down under the shelves to reach the socket every time I want to turn it on/off.

    Can someone explain to me what is going on at this end? I have also noticed a bit of movement left-right-left on the main spindle all the way through which is a bit frustrating, what causes this?

    Nice one, that is an interesting little lathe.
    I gather the Lorch lathes were very high quality machines, it is a shame about the butchered bed at the head stock end but that indexing wheel to the left of the head stock is well cool.
    Good luck on your journey through lathe ownership. :thumbup:

    I have no experience with anything like this so can you explain what the indexing wheel does please?

    It's a pity someone's taken a hacksaw to the bed and cut a huge chunk out of it. I can't believe that that is factory original :rolleyes:

    Yes but about to go out so here is the first video I found.



    It should give you an idea though I remember the author been a bit tedious.

    Basically used to position work in the chuck for tool post drilling or light milling operations.

    It allows you to revolve the drive spindle in small increments precisely and repeatedly,for set positions.

    I was going to suggest looking for an old Myford countershaft unit if you didn't have one, which is what I found at a reasonable price on ebay. Here is a screen shot, the unit that would work on your lathe is the MA 61 on the left. I have the model on the right for modern V-belts.

    Yeah, but it was obviously modified for purpose. It appears to be from the same vintage as mine.

    I believe it was used previously to make parts for musical instruments. I guess they could get much larger dia through there by cutting the bed. Doesn't bother me in the slightest as its perfectly useable as it is.

    I would love a MA 97 for my Drummond but that is a different story.

    Do you need trouser clips to operate that?
