Not much done over the weekend, more kitchen hard labour and a trip to Alton Towers water park yesterday. We do however have the beginnings of the left hand side motion

Valve rod has been modified to have the forked end into the expansion link and seperate lifting link added within the fork. The valve rod is free to slide in the "forward" slot of the expansion link. in fact the whole lifting mechanism works as prototype at the moment :D

 

Return crank and eccentric rod next to see if it all works :blink:

That looks superb Ian. A top quality bit of modelling there mister.

Nice work with the forked end/lifting arrangement, but if you don't mind me saying so, the valve rod looks a bit too long. The front boss should align with the middle of the valve cross-head slides. If it doesn't, then the relationship with the combination lever and anchor link to the cross-head will be wrong.

 

Regards,

 

Dave.

true, that's on the list, but will involve some complicated laminating to shorten the rod. Took a lot of checking to determine that the rod itself is too long. I am going to do the accentric rod first though just tome make sure ......
