Title: Aligning Prop Shafts
Post by: Ticonderoga on March 03, 2010, 07:22:58 AM
Hi All,

I am looking for some advice on how to quickly and reliably align prop shafts. Does anyone have any tips?

Thanks,

Tico

If you want a commercial solution then Brian Ward has been punting these out for a long time, so they must be OK.

If you are using the brass collets with plastic inserts, one of the standard metal centre brass tubes is a good fit over the splined ends of the collets - just cut the tube to length of the plastic UJ and slip over the splines.The you can adjust the motor and shaft outer in all planes and end float. To get the brass tube out just unscrew the shaft from the after collet and things will slip in and out ok.
