Re: Putting a DR back "on face"

Quote:Another alternative is Electroless Nickel plating. This process has an advantage in that it distributes a uniform coating of Nickel/Phosphorus on a complex surface - something that is problematic with electroplating. During a normal electroplating process, electrical potential is higher on sharp corners and edges; thus plating material builds up in those areas. Conversely, electrical potential is less in concavities; thus plating material is thinner there.
There is another way. If it is only a few thou to make up, find a company that can Industrial hard chrome plate. This is not like decorative plating it is used to build up the bearing housings for turbine engine and the like. Pal of mine used to get my stuff done out the back of Rolls Royce engine plant till it moved.
Still even if you have to pay for $100 or so they can build up the lumps and hook till you can put it back on face with no danger to the action. IHC is a molecular bond to the steel and is harder than the steel itself. They can immerse just the lumps or just the hook and mask off the rest etc so you can cure all types of jointing problems with a little forethought.
Never tried it on a worn chamber but thinking about it now as I am typing this, that might be possible also by plugging in front of the throat and then reaming afterwards with a carbide reamer.
I will make some enquiries about that I can see that being quite usefull in some situations, for a pitted chamber, ream it a little deep to clean up the pits, plate it to gain a few thou back and ream again to the correct depth???
Worth asking I think.

Electroless Ni/P has great friction and wear properties that would be ideal for hinge pins, locking bolts and chambers.
Anyway, I like electroless nickel!
