Harrison L5 rescue
micktoon:
:update: :update: Well I have FINALLY got back to doing the Harrison, As Graeme suspected the painting was putting me off and after spending two full days sanding , scraping and bodging I was right to be put off lol .
This is the stage the lathe was at from last time, I had to jog my memory what was and was not done.
I then had to strip some bits off to make the prep for paint easier , which seemed like the wrong thing to do after its took so long to get back to ! Its the only way to get into things really though. This is after some parts removed and the bits that are still on have been masked up. You can not tell on the photos really but the castings are all back to bare metal so all the factory filler is off so quite a bit of filler needed, all horrible places to sand down too edges to stub fingers on etc. All inside the webs on the bed casting needed sanding and inside the cabinet.
Not to mention this little lot and a few more brackets etc that are not in the photo, every bit needs filler and sanding , all the stuff with gray paint on, had been painted by some naughty school boy as a punishment at some point so all has to be removed as its old caoch paint and scratched and battered and will probably react with the new paint, this is inside most of the covers too so lots of elbow grease involved in getting it al off or to a stage where its sound and smooth.
This is the pile of bits after the process, all dents and scratches etc filled and all the old paint gone or sanded to a decent lower layer, The cabinet door with Harrison cast into it still needs more work as it has horrible old paint around the raised letters , this will be pain to get off but the base layer of grey is not bad so I dont want to strip the paint right off as the casting will no doubt be rough and full of filler. I am going to etch prime the lot , check if any more filler is needed then high build primer the lot and the lathe too and do the apron, saddle , gearbox and tailstock as seperate job after...oh and the light the suds tank and frame....... oh and the motor and mounts ....oh and the steadies
This is the lathe after a few sessions of filler and sanding , I have brush painted etch primer inside the cabinet and on the lower section I will give this a light sand and spray another coat over it when I spray the lathe, I have also sealed around the usual edges that trap oil and crap and done the same around seams on the splash guard. I am hoping to get it etch primed and primed tomorrow, Then a final rub down and grey paint which will be next week now. The plan is to get all this lot painted and then I can assemble the belt guards , motor , electrics box , cabinet doors etc then prep and paint all the other parts the other parts.
Cheers Mick.

Nice one Mick, We'll keep willing you on to finish her this time,she's gonna be a classy looker.
It was this lathe project of yours that originally guided me to this forum and as I've said previous I own an L6 MK1. I can see from your photo album the gearbox internals are pretty much identical to my own. We have both arrived at a similar solution for the rattly clutch fix except my oversize replacement pins were machined from carbon steel,I would have preferred the rollers you used but I never thought about that option at the time(May 2013). The other problem we've both encountered and arrived at similar solution is the burrs raised on the gear bevels (mine are also sporting evidence of clumsy gear changes) you solved it with diamond files and stones,and I'm going to use diamond discs in the rotary tool to correct the damage.
I picked up a couple of the original Harrison 'C' spanners of the internet for dismantling and adjusting the headstock taper bearing lock rings,some brute has been at them with pin punch in the past.
Did you fit new Timkens in the headstock? if so where did you get them from and what sort of price?...OZ.

Cheers John , Oz I did replace the bearings , They were Timkens but I replaced them with a cheaper make but same spec , it ended up about £100 for the two taper bearings and races, the front one has a flange on the race to set the depth, G&Mtools on Ebay did have new old stock for some Harrison Bearings so if you know the numbers you might be lucky. What spindle nose does your L6 have ? , I have been told they are the same as mine , that is two and a quarter inch 6tpi Whitworth, I still need a drive plate and face plate if they are the L6 fitment it might be easier to find them.
:update: Well after another day of none stop masking last minute rubbing down and general cleaning spray guns etc etc , I have made some more progress.
A bit more masking off of machined surfaces and a general sort out and sweep up, panels arranged upside down to do the etch primer underside then once dry turn them over and do the side that matters.
All coated in self etch primer , no nasty surprises and it always looks better when things become one colour , you fell like you are finally getting somewhere. I fitted the one door back onto the cabinet but the other needs a good go over so the primer would not have got done today if I had got the cast door ready too so will do that in with the next batch of parts. It took a bit of messing about to do one side then the other then move some parts so there was room for the other bits but got there in the end.
As I was doing the etch primer I could hear screaching from the compressor belt and the rate at which the pump going was varied, as the etch was drying I truied to tighten up the belt but the motor was already as far as it would go so I had to drill four holes in about 10mm plate where the motor mounts and file them into slots joining the exhisting holes , the compressor if in a cupboard so not an easy task took about two hours but did the job. I then sprayed three coates of high build two pack primer, the castings etc got a bit more so they will flat down nice and smooth, all went well and no reactions of paint so as long as its dried without a hitch its almost ready for the gray top coat. These last shots were taken with the primer still wet.
Cheers Mick

Mick that is looking superb :thumbup:
Don't you find that the overspray gets everywhere? I was amazed, when I had to spray my Edwards folder indoors, that although I'd put sheets up and lined the floor, and was careful to be lenient with the gun, a fine sticky dust settled all over the place :scratch:
