Imperia cutter grinder

[George JervisParticipant @georgejervis86082]

HI everyone,

I brought a the toy a Imperia cutter grinder with a good selection of attachments to go with it, it also came with a instruction Manuel from Tony's lathe website. I've tried to research more pictures and information on the internet, but there is very little to go on does anybody have one of these or have used one

Many thanks

George

Some of the tables and charts used with a clarkson may be useful ! Noel.

I've managed to clean and free most of of it up today it seems to be in fairly good condition , just wondered if anyone else had used or heard of these grinders?

Hi everyone,

Would any kind member of the forum know where I could buy a flat belt for the grinder please it's 1 inch wide by 19.5 long

Many thanks

Simplybearings do them 25mm wide and 10mm increments in length but £35 ish

Seem to remember that Lathes UK do flat belts, other way is to get a poly vee belt and turn it inside out, car timing belts etc, if you cannot get exact length perhaps a jockey wheel to tension?

I go with baz, polyVee or timing belt inside out, did it on a clarkson worked fine and cost effective. Noel.

No need to turn a polyVee belt inside out. The soft Vee side works just fine on flat belt pulleys.

I'd be unsurprised to discover that a polyVee used in that manner actually outperforms an old style leather belt working at (too) short centres on a small lathe. Worked well on my SouthBend Heavy 10. Much better than the leather belt it came with but that was old and neglected.

The back sides of both polyVee and timing belts are generally not that good as driving surfaces. By design in most cases as the back side just runs over a tensioning pulley so low friction reduces belt wear. Double drive surface belts where both sides drive things are somewhat different to the usual type.

Grinding wheel drives should only be just good enough to transmit the power needed for normal use and wheel dressing. That way if you do get a serious dig or jam up the wheel stalls before serious damage is done or, quell horror, it bursts.

Thank you Noel,

I've consider using a small timing belt but worried about the thickness of it, but if I turned it inside out would the teeth thickness stop the belt flexing enough around the contour of the pulley which is slightly domed, I've never used any machinery with flat belts before?

Many thanks for advise
