I used to hate TLA's when I was working....

Thought I'd seen the end of them...

I bought my spare belts from Beeline engineering in Milton Keynes, they worked out to be about £6-7 ea..much cheaper than the likes of Warco/Chester or even Ebay

The belts themselves are 5mm wide, the length did vary with machine....730 seems to stick in my mind...

Generally, If you have a 160XL Coged belt, you need a 5M720 V-Belt.
If you have a 170XL Coged belt, you need a 5M730 V-Belt.
Should you use a 5M720 V-Belt with the 170XL Coged belt the V- Belt will be too short.
Using the 5M730 V-Belt with the 160XL Coged belt, the V-belt will be too long.

Go to your local electrical factors and ask for a 240-110V AC control transformer....

Dont know your location but here's an example....

The cross slide lead screw is M8 with a lh thread.

I had to make a new one for my 9 x 20 when the original snapped...Silver steel is good enough for a replacement..

David, I sent you a private message....disregard it if the mill is new and under guarantee...

the power semiconductoir devices are thyristors ( scr ) and form part of a full wave rectifier bridge across the mains...one or more is defective if you read 0 ohms...

You arent cutting up the 'lightning struck' Bilsdale tv mast are you?

FWIW,

I have a similar machine to the WM290 which originally came with a dc drive.

I changed the motor to a 2 pole 2800rpm 1.1kw 3 phase motor in an 80 frame size, it occupies the same space as vacated by the dc motor.

I used an Invertek vfd and set the max frequency to approx 72 Hz to give me the same spindle speeds as before.

I had no need to change belts or pulleys.

I used the existing speed control pot, rewired the FWD/REV switch to give the desired functionality for the vfd.

No additional switches or buttons.

Folk who offer magneto winding services may be able to remagnetise it for you…

Selling on Ebay has now become less attractive....Gone are the fees paid to Paypal because the buyer pays directly to Ebay and they in turn pass on the proceeds to the seller after taking their cut...

From what I can gather Ebay fees are now more than what Paypal would have charged plus the selling fee for Ebay combined...making it less attractive to sell a low value item inc postage.

As a consequence of this, even buying would be less attractive too because sellers are likely to increase their prices to accomodate the rise in fees.

John Fletcher, pm sent...please.

I asked him "what work exactly has been done to this compressor as it is described as 'seller refurbished', did you use any spares?" (potential for mis-selling, not as described)

It wouldn't surprise me if it didn't sell....

Just got a reply on the instructions...£20....Greedy!!

There is an error....

The default M display is 0 not 1 as written...showing spindle speed.

Hope this of use....

Running in reverse with a lower speed is by design on these machines....

Cheers Ian....

Just about sorted it now..

Ian,

I've sent you a pm...

Ian,

Thats a great help...

Should be able to get the machine running as it should now......👍

Thanks.

Ian,

Thanks thats great....Just what I needed.

Do you have any idea on how the buttons work?

I think the green M button switches the motor on, the Red one, off. The two either side cause a change in direction, but what about the + or - buttons...?

Any help appreciated...

I have one of the earlier Warco mini lathes that has the digital speed readout panel whereby the speed is set via touch buttons rather than a speed control potentiometer....

It looks like the machine has been tampered with in the past...

So before I start pestering Warco, if there are any owners of a similar machine, could they tell me where is the little speed pick up board secured inside the end housing where the change gears reside?

I can see the slotted disc, but there's nowhere for the opto coupler device to be secured....I cant see how it attaches...

A photo would be a great help...

Many thanks

J.
