Could be a first angle vs third angle projection thing - Mr Evans occasionally forgot which he was using in the same set of drawings (or maybe other people were doing the drawing on some details).

Hi

Some more assembly work. Fit the piston rings



The piston ring clamp/guide I made won't work will it  :facepalm: If I use it to fit the piston I won't be able to get it off so a slight mod is required, cut a slot in it










Slightly off topic I have modified the lift. it now bolts to the front and rear beams using the buffer mounting holes



The 4 socket head cap screws in each valve rod guide have been replaced and reversed with button head screws to give a little more clearance. The lock nuts on the valve rods were just fouling the nuts.



Things are getting a little stiffer now, mostly caused by the piston rings but it still turns over ok. Once I get it running on air it should bed in


Cheers

Rich

Still following along quietly Rich. Lots of great progress recently which you must be pleased with. These loco builds are just fascinating to me and your build log and pictures are excellent.

Hi

Thanks Chris, Kim, Roger, Carl and Bill  :ThumbsUp:

The little crank I made that is the drive for the mechanical lubricator is pinned to the crank pin which once fitted prevents removal of the connecting rod and coupling rod  :thinking:



I decided it would be better to make one that is removable. Drill 2 holes in a bit of steel and slit with a slitting saw and ream



Cross drill tapping size for M2.5. Drill one side clearance for 2.5mm and tap the other side.







Thats better





The coupling that connects the valve rods is slightly out of line on the left hand side



I shall have to make another

Finally for this weekend I have made 4 pins from stainless steel that connect the eccentric rods to the expansion link





Cheers

Rich
