Hi all,

So I am finally getting around to converting my Warco WM250 to 3ph. However, I am stuck as to which belt to select.

I wish to use a taper lock pulley for ease, but most appear to be for Z or SPZ belts, whereas the lathe takes 5mm wide polyflex type belts (as far as I can tell).

Can anyone recommend a taper lock pulley and/or belt that would be suitable, please?

Many thanks in advance,

Hi Tom,

Try contacting someone like "Fenner" direct, or maybe a local power transmission component supplier.

Thank you, chaps. I had rather hoped for an off the shelf solution, which I suppose Fenner may have.

Neils, I like what you did with your 250. Shame the Warco version doesn't have the holes in the back of the bed for the motor.

To drill and tap 4 M8 holes more or less as shown in the cheap and lousy chineese cast iron bed is not a sin like schratching a Myford or Boxford will be.

The intermidiate aluminium disk was some leftover from windmill manufacture and is more usefull on my lathe.

The beauty of Fenner Powertwist belts are that they can be rolled on the two disc sheaves without harm.

When loosing grip with wear or time it is easy to remove one link.

If You roll over the slim Gates 5M belt it is hurt.The beauty of the Gates 5M is that it will go round 28mm where the powertwist Z is not really well below 60mm diameter.
