Re: BP II duplicator conversion

Guys,
Peter Renolds (prenolds@...) has used this method long
before I did, he told me about the 150lb value, even though I used
adjustable gas springs from McMaster-Carr.
Peter can provide excellent feedback/info.He has a lot more
experience than I do, he has helped & guided me a lot. I'm just a
rookie getting his feet wet, he is a seasoned pro.
Thanks,Femi

the application of the "shocks" on the knee. As noted, the machine
I was investigating does not have any type of screw knee height
adjustment...just a hydraulic ram (nuts!). I will check with Femi
and see if he has other photos to continue my education!
