Paul,  Sorry for the confusion, but I realised last night that the
 counterweight is what I want to attach to.  All the spacer does is
 hold my flex coupling attachment plate up 20mm from the counterweight
 so that the plate is centered on the 50mm flexcoupling. Hopefully it
 is clearer now??  The ring will center on the boss on the
 counterweight, and in turn will center my flex coupling  plate.

 Neil.

 Somehow this got sent out with out my comments.

 Do you have a jpg of your flex coupling?

 Paul Lamar


 Paul,  No I do not,  It was water cut and the OD is 130mm.  The holes
 were water cut as well.  Come to think of it that mob should have the
 dimensions to do the spacer as well.  Will investigate.

Neil.

I take it there are two plates with some sort of rubber bushing
between them.  Is that correct?  In that case a little bit of axial
misalignment
may not hurt.

Paul Lamar

Paul,  yes there is a rubber bushing to allow for flex.  I am thinking that
I have the wrong measurements as well.  Do you know the height from the
face
of the counterweight and the top of the E shaft that sticks out from the
fastening nut?  I am just being lazy and really will have to dismantle my
set up to get accurate measurements.  Looks like I know what I am doing
today!

Neil.


I'll get back to you in 24 hours on that.

Paul Lamar

The threaded eccentric shaft extends out of the counter weight 12 mm'

Please take a picture of the flex plate you have. I may have another
idea.

I think you mean out when you say:

"All the spacer does is
 hold my flex coupling attachment plate up 20mm from the counterweight
 so that the plate is centered on the 50mm flexcoupling."


Here is a plan

20 mm is .787 inches

Use the roller bearing bore in the center of the e-shaft
as a pilot. There is .8 inch diameter short shaft that can be inserted
into this bore and that will pilot the spacer. Remove the stock
roller bearing as you don't need it.

The new spacer is sort of blue in color in these jpgs.

Paul Lamar


Paul,   All is well, the crowd I use to machine up the redrive have all the
measurements on file.  Pulled everything apart yesterday and got all
required measurements.  Now I am busy machining up a jig for the welding up
of the other bits.  Thanks again.
   Do you have a current price on the gear set??

Neil.

It is roughly $200 US
If you need an exact figure I can call tomorrow.
