Here's a dopey question

[RIDE-RED 350r]

So I know that in the powersports world, quite a few outfits offer replating service/cylinder exchange for nikasil plated cylinders that have sustained too much damage to be simply cleaned up and re-used.

Is there anyone out there who does this for saw cylinders?? Or is the cost of replating just not sensible with the new lower prices on cylinder kits?? It just seems like kind of a waste to toss a cylinder that simply needs replating. Just curious....

$200 is going rate on them.

It's way more expensive to replate a blind cylinder, ( non-removable head) and quality can suffer sometimes. US Chrome does replateing. I believe @srcarr52 has had some replated

 

[Mastermind]

I think US Chrome is the only company that will do a blind jug. Was it Millennial Chrome that used to do them too?

 

[RIDE-RED 350r]

Well that certainly quells my curiosity on the issue, cost and very few who will replate a blind jug. Thanks fellas

 

[Deets066]

Not usually a good option unless it's an NLA jug

 

[Adirondackstihl]

Yep
US Chrome

Sometimes $200 is the cheaper route

I have had powerseal down in pa do a few cyl...have had very good luck with them...not sure if they will do a blind cyl though...

Anyone know how this process is done?

If you have a cylinder replated does that mean a custom piston is needed to account for the difference in bore diameter ? Or can they adjust the plating thickness to bring it back to oem dimensions?

They bring it back to OEM

If I'm not mistaken Cliff H had his cylinders done by US Chrome.The stroker cranks came from Falicon in Clear Water Fla .Keep in mind though these are high end race saws .This stuff is way out of my league .I did once make and install a cast iron cylinder liner in a 125 McCulloch but that an entirely different subject .

Had to send them my piston with cylinder, when I had a snowmobile jug done.

 

[mdavlee]

Milennium does cylinders with the heads cut off. Send the piston with the cylinder and tell them desired clearance.

 

[Adirondackstihl]

Yep
Just send the intended piston you plan on using with the cylinder.
They'll hone the nikasil to the proper ID

Ed Heard had several cylinders done at US Chrome. He said the plating is a lot harder than OEM, so do your porting before sending the cylinder down. He said carbide bits will barely cut through US Chrome's Nikasil.

 

[mdavlee]

Millenium is the same way. Adam said it is real hard and will take a seizure just fine and clean up easy.

Electrode-deposited.
not unlike a lot of other plating processes. I believe nickel silica-carbide is the material deposited.
think gold or nickel plating

Yes. Interesting process.

The pool of nikasil is continually moving. The nickel is simply there to deposit the carbide on the bore. Fascinating stuff.

"Nikasil" is just a trade name Mahl used for the process .Whatever US Chrome or anybody else brewed up may or may not be the exact thing .
