My new Harrison lathe

[God mode restorations]

Pins are a complete pain to remove. Not heat nor smacking got some of mine out on the Denbigh. Eventually I soaked the whole thing in oil and waited a day, then we got some very minor movements... such a nuisance.

Yer definitely a pain to remove. Soaked this for a few days. Then gave it plenty of heat. And after a few hours there was movement.

I’ve been thinking about making a hoist over the lathe for a while, the steady I can just manage, but the 16” 4 jaw is out of the question on my own and there’s never a helper when you want one.

Probably end up using a cheep eBay electric hoist, for the price it would be crazy to use anything else.

Yes they save a lot of time and effort in trying to lift and potentially hurting ya self or dropping the chuck on the ways.

After stripping the cases off you can clearly see at some point one of the cases has been dropped and badly repaired..I cant except this kind of repair. I will leave the parts intact and nickel weld both inside and out.

Not sure how much luck you'll have nickel welding over that braze. I'd be more inclined to die grind it out and re-braze it properly a bit at a time.

I am going to grind the lot out. I forgot to mention that

On thin stuff like that I prefer braze
Looks like they veed out so a big weld to refill which may cause trouble

Robin renzeti on YouTube converted a recip saw into a power scraper. With his meticulous nature its better made thsn a biax

His work and detail is fantastic

Hes a old school thou splitting toolmaker.
My instrument maker pal is pedantic like that, takes forever to do anything!

Yer there is some wide v joints in there. Cant leave it like that...

A little more black for ya.

I think you're going to have a lot of trouble trying to weld that.
The slightest bit of braze is likely to create a big mess, and even if you do manage to grind every last bit out I think you'll have huge V's and gaps that'll be very hard to fill.

I'd be considering doing a better job with brazing.

The main reason I prefer the nickel is I dont pre heat. I run it in warm. I will study it tomorrow and get the paint off so I can properly assess

You live in Colchester, but you have got a Harrison! I would keep quiet about that if I were you! Still I suppose it's all 600 Group now! Still watching it and loving it, what a machine, and what wonderful work you are doing to it! Have you found a model number for it yet?

Lol
I have a colchester as well. Yes the 600 group are still here. There are no model numbers or any information available. The company I brought it from had it from new . The original documents are buried in there archives and have promised to find them for me. From the bits of information I have had from different sources indicate that it's most probably a off built by Harrison specifically for the company I got it from. Date wise I believe its pre war but cant be certain . Its an awesome machine and will be awesome to use.

Today's tasks.
Remove the plaque.
Mix a batch of caustic for paint removal. After studying the very bad repair it will be hit and miss. It has an awful lot of fractures the camera doesn't pick up. If it's not viable then I will hand fab a replica. Time will tell. It's now sitting in the caustic so shouldn't take long. I was going to do the steady at the same time but need a bigger tank for that.

Paint stripped.
Half hour in that nasty crap sorts it out.

Given what a jig saw the break was, it does not look too bad a job on the outer side? If its sound - filler?

Yes I agree. It's not to bad. The welds are a little shallow. I will most probably leave as is but tidy the inside up and just generally make good.

That is what I would be doing but I am not Spencer.
