Big End Advise Please

[Mark McKibbin]

Sounds like it lasted a good long time before coming loose then Hedd - as mentioned, I prefer to use a spring washer and Loctite in favour of the tab washer.

Mark,  it strikes me that you may have access to some rather good facilities.  This is my rod boring jig, it was kindly given to me by a very good friend who also made the adaptor plate for my Boxford.  I have never seen another in the flesh but found one reference to it on the Internet (it is built for a Myford).  The trickiest issue is centralising the big end for boring (I mostly bore out old white metal to suit Pheonix cranks).  

That is a very nice piece of kit, how do you adjust the height?
