New to me - Colchester Triumph

[Lewis_RX8]

What lathe is that?

I assume he also has a triumph by the wording lol

He managed to get the QCTP on by the looks of it and i remember you having a lot of bother and deciding not to fit one in the end as you would have to butcher the cross slide was it?

It's a Kerry AG, I posted about it a few months ago

It's the Kerry AG I got a few months ago, apologise I was just talking in general terms regards missing gaps, what was the problem with fitting the toolpost? I didn't touch the lathe to make it fit, just measured up the slot and milled up the base that came with the toolpost

Seems to work although, I only made it last week and I've not had much time to get to grips with it all with working away

Yes thats it.
I have learnt to live with the 4 way. Massively rigid.
Bit of a pain using shims to get centre height spot on.
I now have a parting off tool. Standard cut tool and a fine finish fitted. Leave one spare.

I was struggling to find a decent 4 way to fit mine so ended up with this, it originally came with the lantern style...

Oh my mistake, nice looking lathe that just had a look on lathes.co.uk

Never even heard of the lantern style one , look intresting but a bit of a faff

Really looking forward to the rigidity of this machine after using a mini lathe, Not that I've got to balls to do depths of cut high enough to use all the horsepower and rigidity
Alot of my tools are from the bloke selling and looks like he has already welded some shims onto them so could save me a bit of messing around. If the tailstock is at centre which it hopefully is unlike your one originally. Atleast other tools only need shimmed once same as setting height on QCTP and for the cost of them and butchering the casting I know which one I would have.

Yes my thoughts exactly.
I have tried some pretty hefty cuts and the lathe just laughed at them.

The lantern was a pain to set, why would you have to butcher the casting?

<<The lantern was a pain to set, why would you have to butcher the casting?>>

Look at the diagram at the bottom of post #111. The Triumphs came with one of two styles of compound slide casting: one with an inverted T-slot like your own, the other with an integral stub to suit the 4-way post.

Thanks, missed that

Ditto with my L5 and the Triumph is a more powerful lathe. Power being very much the limiting factor rather than stiffness on decent lathes.

It's really hard to say what DoC it will do as it depends on the type of material as well as if you are using coolant or not as well as what type of tool. Carbide isn't that sharp and effectively brute forces its way through while HSS will cut instead but can't tolerate the same kind of heat that carbide will. While seeing what mine will do I've had red hot chips being fired at a massive rate off it!

Either way it will be massively, massively better than any mini-lathe!

Tool post apart and hopefully refurbed and back together tonight we'll see how I get on

Quite sludgy old grease here so glad I took the plunge to take apart not as hard as I thought

All in bits don't think I've lost any springs or bearing so all kept safe in a bag

Getting on with the big parts first in the washer and attacking with some scotch brite

And ways look good on this aswell

Just thinking of what I will grease and what I will leave to oil when I put it back together.

And that photo of the topslide shows why you cant use a QCTP.
One huge central post - one piece with the slide.
Certainly is extremely rigid

Didn't stop me on the Student I had, off with his head Best mod I ever did to the lathe, well that and the DRO.

Could always modify one to fit though.

 

[fizzy]

Nah its sacrilege
Got used to it now.
And spare holders are far from cheap.

Make your own.

I think if I had a working 4 way I'd be happy enough. Am i right in saying that if you buy all the same size tools, then they all run with the same centre height? I've watched Kurtis from CEE swap out tools all the same height in his 4 way, no shims. But he runs 4 way tool posts because of rigidity for huge tools etc. Any qctp will have more overhang and less rigidity.

 

[Hood]

Rigidity? Oh, must have misunderstood thought we were talking about Colchesters

 

[Hood]

Btw the student had a good working 4 way but QC was way better IMO. First thing I did when I got the triumph was put a QC on instead of the 4 way.
