Anyone on RR know about Chrome Plating?
Can one chrome a mainshaft or will it add too much material?

Does it help to clean and polish parts before handing over to the chroming facility?

Can an already chromed part be rechromed?

What steel components on our helis cannot be successfully chromed?
The lot I got is not a lot, but I thank God a lot for the lot I got!

not an expert but here's my experience,,

Chances are the .002 to .003 typically accumulated during the plating process will exceed your bearing clearance preventing the shaft from slip fitting. you might be able to freeze the shaft and heat the bearing for assembly but it's a crap shoot imo.

My plating vendor prefers to do prep work for total control.

Seems as if I remember crashing a stork with a chromed shaft years ago. .080 out of round. Chrome flaked at the bend but not at the bearing. I straightened it and flew again.

Shops do rechrome everyday, but again controlling dimension is the variable.

what steel can be successfully is as always only limited by budget.

ymmv

now what are you up to Mike?

i wouldn't chrome a main shaft. Depending on the tolerances, it could have a very bad outcome....especially if it's German.

Nope... Chrome plating will be way too thick. Clearance for the bearings is less than .001" and the plating is at least .003 per side making the diameter .006" larger. You still need the swash to move the the head to fit.

Thanks guys! Obviously mainshafts are out of the question then.

madgadget,
I'm building several Schluter machines which will have customized G10 frames.
I'd like to get all the metal parts chromed. Schluter originally just zinced them and they've lost their new look. The Superior and Champion would look really swanky with all their head parts chromed.
Obviously the only thing to be done with the aluminum bits would be reanodizing.
The lot I got is not a lot, but I thank God a lot for the lot I got!

Not only that , it would make your main shaft cost about $300 each....

Just had $6000 worth of chrome done on a restored 68 Torino GT.

Appearance chrome is different from hard chrome. You can chrome aluminum but it's best to polish aluminum and it's less costly.Part 107.

They also have a paint on chrome system now. Much less expensive for some chrome work.

If you really had to have a chrome main shaft, you could turn a couple thousands off the shaft in a lathe and then chrome.
