Love those acorn nuts, and the router bit trick.  :popcorn:

Wow, more "features"  :facepalm:

At least you have them mostly sorted, or a plan to sort them.  Email from our machinist friends overseas this morning: can they rotate a bolt pattern and re-drill (sounds like they bored the first ones too deep and made a hole from the inside of a valve body to the outside...but that won't be really clear until we see the parts most likely)

Wow, more "features"  :facepalm:

Fun aren't they. I'll show you this one and how I fixed it if you don't let on  ;)

I decided I better check all the crankshaft bearings lined up and


 :rant: No they didn't. While I had correctly located the holes in the central casting I had not checked the other two. Having put them on a surface plate they were found to be 2mm low  :toilet_claw: Time for a cheat, no one is watching this thread :paranoia: so

Turn up a piece of bar the diameter of the outside of the bearing with a 8mm hole in it to save time when I carefully mill it down to 2mm thick:


Cut it off just under the inside flange measurement of the bearings:


Pop it into place to check it looks right  :-X


I think we got away with that  ::)

I am pleased to report a long piece of bar goes straight through the four bearings and goes round and round  :naughty:


I found a casting  :pinkelephant: its the last one  :Director: We will need some more... In the meantime..


Doesn't that look pretty  ;D No its another  :censored: one when you look closer:


And it is not recoverable sufficient to have a shiny rim  :ShakeHead:


Decorative paintwork will be the name of the game  :-\ But  it looks to be time to start the negotiation for another set of castings  :cartwheel:  :wine1:

Nice shim recovery! 

And I thought the same thing on the flywheel, a bit of putty and paint and it'll do.

Mean time I have my company coming to my office on a daily basis asking if we can substitute materials to make up for shortages...sigh.  If you think the price of plain steel is getting outrageous, try sourcing more exotic alloys (17-7 PH stainless, amongst others).  I may have to dig in harder on my retirement plans.

I'd say nice save with the shims, but none of us are watching so I didn't see that...  :Lol:

Did you glue the non-save :-X into place to make it stay ?

Fine result, as usual  :cheers:

Thanks Guys  :)

Yes  ;)  No one should ever know on the finished model as it is hidden behind the flanges on the bearings  :-X

What shims? :noidea:  I didn’t see a thing!

Watching this build with interest Jo.  I find it entertaining, if not remarkable, how you salvage errors in previous peoples work. :NotWorthy:

Thank you Craig,

I believe it is just as important to know how to remove features as it is to find new and ingenious ways to apply your own    :facepalm2:

I'll echo what Craig (and others) said, and add that they are also valuable lessons on salvaging errors in my own work!
