Colchester triumph 2000 in NS

Halifax, $6,750

It does have the usual accessories with it and is being used. Go have a good look at it in person. Might be a little higher price than in other regions (where machines are more plentiful) but seems like a reasonable price to me for your region. Maybe there is some wiggle room (hence the in-person contact)?
 
If this was in AB, and there was little wear on the bed it would be an excellent price for this type of a machine. Very, very good price. I am not sure about NS pricing. But I doubt NS is a machine rich area.

It's a lot of money for a hobbiest. But it's a Colchester. It's also a bit bigger than the average hobby machine. If you think you need that much machine and if you can see it running and put it through its paces so you know the bearings, gears, and screws are all good, and if the ways are in good shape, then I think it's worth that even here in Ontario.

I think it boils down to your needs and the actual condition vs claimed.
 
Condition is everything... and I'd care how they managed the electrics of the motor change...

IF I was purchasing it I'd look in person very closely and open the electrical cabinet to see what they changed if anything.

I'd try to knock the price down to 6K as well, but if I had to I'd pay $6500 but no more.
 
Just a note, that in Calgary on Auction a nice Taiwanese machine is over 5000 CAD for the 14x 40 size. This one is bigger bore (I think D1-6) and 15 x 50 plus its Colchester. So in say same condition they cannot just be $1000 apart - auction price (!) And be Colchester be seen as high?

We also had another machine go for around 6000 CAD and it was a 13 x 40 Harrison so smaller British lathe would be same price as much bigger British lathe? Assuming similar condition?

What does Dabbler think?
 
@Marknb - I'm glad to see @TorontoBuilder chime in on your thread. He has been shopping for Colchester lathes and is quite familiar with the current market. I would trust his advice as given above - especially as it relates to condition.

I hope the lathe is as described and that you are able to make a deal. Please keep us posted!

If I look at it, anything specific to look for on the electrical side? Or more of a clean install vs a mess?
 
Check the single phase motor for hp rating: OEM is 7.5hp. What is a bit odd is that right behind the lathe on the wall (first pic of the add) there is a 3 ph panel. Why would they switch to 1ph if they have 3ph? Make it easier to sell?

Generally, installing a 1ph motor into a 3ph circuit is not difficult. Circuit can basically be the same as long as correct size conductors and components (relays, switches, etc) are used. A 3ph relay can be used to control 1ph power - but not the other way around.

From factory, the power distribution box uses the DIN standard components and layout typical of European machines: no loose wires, everything neatly tucked away in wire tracks, everything labelled, etc.

If the panel still looks like that and everything works electrically, I would have confidence that they did a decent 3ph to 1ph conversion.

Absolutely correct even busy bee sold their lathes with electrical cabinets that could be upgraded from 2 to 3 phase. The other way around not so easy or clean and I'm always suspicious when I see someone's ad say "230v single phase" without providing greater clarity.

Given the complexity of such a change I suspect, and hope what they've done is just bolt on a phase converter to the rear of the lathe to accept "230v single phase" and replace the 600v with 240v 3 phase motor. This is all that has been done with our 600 volt colchester.

Ask specifically about this, inspect the cabinet and look for all original components and clean installation... be wary of anything else or you could be buying someone elses headache

look for evidence that they replaced the 600v motor with a 240v 3 phase motor and installed a phase converter box onto the rear of the lathe.

I have never seen a 600v machine converted to use a single phase motor. I've only ever seen voltage reductions, and in a few cases a static phase converter attached directly to the lathe to convert to 3 phase electric.

IIRC the triumph and master lathes forward and reverse is accomplished via the matrix clutch system and therefore the electrical cabinet lacks a reversing contactor.

The original electrics are designed for a 600v three phase 7.5 HP motor and a small coolant pump with a total load of around 11 amps or so.... converting to single phase 240v motor would quadruple the amperage requirement and likely exceed the capacity of the installed components particularly the wiring.

IIRC the amperage of a single phase power 240v 7.5 HP motor is about 40 amps, well above what the supply circuit is supposed to carry.

I'd only buy a colchester with 3 phase motor as I described

In many cases you can adjust 3ph 240v panel to use 1ph 240v panel keeping in mind that amps that trip 3ph are 1.7 times less than 1ph for same size motor.

For 600v in all cases I can think off, there would not be enough range on adjustable dial to do the amps change.

For older panels that use heaters you would need to replace these.

So if I had a 600v machine and absolutely needed 1ph I would replace the motor with 240v 1ph of same frame size and if panel used heaters just got new ones. If panel used adjustable dial in amp meters I would need to get new one at around $20 - $30.

There also may need to be a control transformer swap involved and if there is a coolant pump it may be an issue.

So overall not a huge deal with a lathe - for say surface grinder with two motors & with a C flange mount + possibly low vibration motor from the factory main blocking points may be finding suitable motor setup plus two motors doubles everything making a transformer much more clean option. For a bandsaw I have same deal, main motor may not be a hassle to switch, but there is also a welder and little grinder motor. Even if I were to remove little grinder I would loose the welder.

BTW, my original Indian lathe was 600v 3ph - it was swapped to 240v 3ph no issues.

triumphs all have coolant pumps, 3 phase. This is why I've only seen conversions to replace with lower voltage 3 phase motors and phase converters

of course you could eschew using coolant.

I'm eager to see what is up with this one

Yep, you either do not use coolant or replace coolant pump or add small transformer for the coolant pump.
