Harrison L5 rescue
Ned Ludd:
Hi Mick,
If you have proper 3Ph wired to your workshop, then that is the way to go. If, however, you are using a converter to power say a mill, with power feeds, suds pump etc, then a converter is a problem, unless it is a rotary one, because of the risk of burning out the smaller motors if the main motor is off. You can obviously wire up the smaller ones to only come on when the main is running, but this can be a hassle.
Faced with this situation I would be tempted to VFD the main motor, but run the smaller ones, which don't necessarily need infinite speed control, from a converter. I know this means two power feeds but could be the best of both worlds.
Ned
PS I am jealous of your machines but most all jealous of the space you must have to fit them all in. :D
Anybody know tonight's lottery winning numbers? :lol:

Evening all , I have got that jig block done and been stripping the lathe more , here is a photo of the jig and the original one I copied, not that its up to much compared to most things on the forum but will do the job fine.
I have spent more time moving things so the Harrison was in the middle of some floor space to get all around it, its now in spot I can get to everything and see what I am doing. I am reaching a stage where I will have to decide how far to go with stripping back.......... Ummm its a tricky one as on the one hand I want to just keep dismantling and do a ground up job, like I would if it was a car but I dont really know enough about lathes to know if I am going too far and will be no better off for it nad setting up things on reassembley. I have already forund out the causes of a few niggles , half the noise is the motor as thats rumbling , it looks like 1939 date on it if thats possible ? and also only 3/4 horse power I am swapping that anyway for 1.5Hp three phase with inverter. The clutch is also rattling and the brass pins are loose in the plates. The power feed engage lever used to drop out and that was crap previous repair, a small plate the lever is meant to latch over but it was just catching the edge of it. Here are a couple of photos anyway.
I had fitted the suds tank when I got the lathe, I think I will remount it on the tailstock end of the lathe this time so I can get to it.
The headstock all looks ok except for the usual mushrooming of the edges of cogs where the kids have tried changing speeds when running, the saddle was the same , I diamond filed all the burrs on them gears and they mesh smooth now. The headstock gears need this too but will mean the whole lot coming out to do it :bugeye: would I be :loco: to do that of daft not to ?
You can see gears better on this shot they are fine once selected but the burrs make selecting harder than it should be.
The tailstock is rough inside , I bought a 3MT reamer but it would not touch it , anyone know the best way of going about cleaning it up ?
Thats it for tonight , the post has taken ages as I got a bit tangled up in the photo department :palm: so have been on hours sorting out what is what. Ned I dont think I could get three phase here as it stops quite a distance from the house and its overhead cables, not to mention the cost, so its inverters and single phase :doh:
Cheers Mick.

You've presumably already read the lathes.co.uk entry on the L5, so I'm guessing you already know that the lathe and cabinet have a very carefully set up relationship that is best left undisturbed.... Other than that, I'd say a lathe is easy compared to a car.
So long as you remember what cog goes where, and how all the springs fit together, it's a doddle :lol:
micktoon:
Aye cheers Ade, I would definitely remember when I took it apart but then be thinking ....Ummm :scratch: was that this way ....or this way when it came to putting it back together :palm: I had read the lathes uk pages and would not take the headstock from the bed or bed from the cabinet , its more should I strip the lot out, gears , spindle, norton box, lead screw saddle etc and inspect , repair anything that looks suspect then paint then re assemble so I know its right or just leave it unless its definitely broken, I am more worried about tollerences and alignment side of things and the fact that if anything breaks taking it apart it will probably have to be made.
Hopefully there might be some forum members with previous experience, it seemed a bit noisy before but the motor is really noisy and the clutch rattles as the brass pins are loose in the plates, i will trial fit the new motor and try to fix the clutch and see if it seems smooth and quiet then.
Cheers Mick.

Hi Mick
Do have a tapper turning attachment ? you could re-turn the tapper in the tail stock barrel :dremel:
Lets see a photo of your other lathe :poke:
