Harrison 140 Project

[Carl Wilson]

Sent to Doubleboost eh? Using a Harrison 140 to repair another Harrison 140.

So I got this mounted temporarily today. Made the spacer 8mm thick...

By the looks you need that spacer to get the tool on centre, or hasn’t it been set up yet?

Yes. The spacer is needed to get the boring bars and the 30mm bore tool holder on centre.

I bought one of these this week, metric gearbox on it, looks exactly the same as yours but labelled as a 11” Harrison.

Identical to mine, great machines. Is yours a high speed headstock version too?

Yeah, basically a spec’d up L5A. So a pretty late model.
L00 Spindle Taper, 3 lever gearbox giving 32 or 36 metric speeds (I forget), but it does have the earlier dog drive assembly of the leadscrew typical of the two lever gearboxes.

looks like you’ve got the two speed motor, quite a spendy option, should be a top speed of 2000RPM in high.
instead of 8 speeds normally from 40 - 1000RPM, you will have 8 addition speeds doubling the lower speeds.

Has it got imperial or metric dials

 

[Tinbasherdan]

It’s worth noting that the 2 speed motor is 3 phase 415v only, I did look into running one on a VFD and it’s a no go. RPC or nothing

Will be metric John, same as mine

how can you tell if it is a high speed

 

[Tinbasherdan]

how can you tell if it is a high speed

2 speed motor, and the headstock bearings are dofferent

 

[doubleboost]

how can you tell if it is a high speed

The speed range goes up to 2000 for the high speed the motor switch has 4 positions 2 forward 2 reverse

 

[NickMc]

thanks for the replies

I’ve got one I can scan to you

I’ve found on on Keith Rucker’s site don’t know if it’s exactly right as you say, it’s very like a 140, but not.

I bought it over the pond, should be landed here next week- got fed up with the stupid prices here or the machine dealers never bothering to call you back or just not interested. Long gone are the days of buying them for few hundred quid(not that I thought I would!). I’ve a bit of experience on a Colchester, but not in about 10 years.

I have a single phase 4hp motor, and a single speed 4.5hp 3ph motor, that I was going to run off a VFD.

Very nice! are these the run outs before the 140 Was introduced I wonder?


Where are you guys picking up
tooling? The local market here is closed because of CV, eBay and the like?
