Hi Gray,

 

thanks for the information 😁 I’ll probably take a closer look when I’m up for the job!

im north of London and thanks for the offer to help I might well need some bearings by the sound of it ….

 

Cheers Ricky

On John MC Said:

Michael G.  That information doesn’t say a lot. Sealed bearings will, of course, have more friction, but how much more?  This information, for me, is elusive.    I wonder if its because the friction is insignificant?  Plenty of information on speed though, a significant reduction needed,.

What if there is a separate oil seal, I’d wager there will be more friction from that than the seal built in to a bearing.

Are the motors a control gear fitted to these machines that feeble they have problems with the friction generated by a seal?

As for “diversions”, why publish a picture of the somewhat poorly designed Emco quill assembly.  Were we expected to look at it and not comment?

This thread started out with the OP wanting to improve his machine, what followed was some helpful info.  I suggested the possibility of going a step further with, probably very little, extra work.  Then the “why bother” comments started.  No good reason to go the final (small) step given.

The way this thread has gone is unfortunate.  The purpose of a forum is to, well, google it.  I’m worried that threads like this discourage users.  A load of self appointed experts (I include myself in that description so as not to cause upset), spouting forth can be quite off putting to those less sure of themselves.

I wish the OP well, I hope his work is successful and please let us know how it goes.

 

 

Graphs are available, lots search oil seal drag
