Nikasil plating..... who's doing it?

[astnmacgto]

Has anybody had a cylinder coated? Is anybody doing the coating? Cost effective for hard to find cylinders?

Let's talk

Us chrome does blind cylinders. $210~

Have you had any done?

I haven't. I knew tons who have on race saw cylinders

Expensive for sure, I guess it would be worth it if you had a special cylinder or one you couldn't get anymore

Yep. Common to have cylinders done after welding

@Lee H has had cylinders done by US Chrome ..

 

[Definitive Dave]

Blind cylinders are regular chainsaw cylinders, right?
Is a topless cylinder for a two piece easier/cheaper to have plated?

The last I heard they were not doing blind cylinders .About the only way to actually know is to call them .

 

[mdavlee]

Us chrome was the only one as of 3 weeks ago. I called several. Millennium and powerseal do open and Powerseal was the cheapest at $184.

Lee has them on speed dial and knows the owner by first name - vice versa.....
No joke

I've had jugs done. Simple process, you send it to them, they send you back a newly plated jug. Oh, this is for snogo jugs. Nothing mysterious about it.

I know whenever I send a cylinder to Powerseal, they want the piston kit as well, or they order one for me. I think they like to measure the kit for clearance. This is for bikes of course, not saws, but I dont see why that would make a difference. Not everyone sells A, B, C, D etc pistons of slightly different tolerances/sizes.

Local buddy of mine sent an 880 jug to US Chrome. They requested the piston he intended to run.

Good to know that they care enough to ask!

This is a very good point. I have had the same thing when I was rebuilding my current 2000 Polaris XCR-800. Millenium asked for the pistons so they could get the tolerances correct. It is so exact now they'll plate the jugs for the pistons.
Wiseco uses forged and machined slugs so they expand at a different rate than the cast pistons. Usually platers will add a little clearance for them.
Now we should discuss the merits of frosting your slugs! If you have a jug freshly plated, why slow down, get that slug frosted too!

I wish I were rebuilding something, I'd get some coatings just to get them.

Frosting? Do tell

Some manufacturers sell pistons with hard anodizing or a silicon/teflon type coating to prolong their life. Pro-X and Namura come to mind first...I have run some of the Namura pistons in a few YZ250s with great success, and they are MUCH cheaper than the Wiseco stuff. Wiseco is usually my last choice- I much prefer cast pistons over forged units.

 

[mdavlee]

I thought about requesting quotes from other manufacturers but a tiny run of 10-20 isn't something good they'd want to mess with

I hear you. I know it is off-topic, but cast do not expand at the same rate as Wiseco forged/machined. Every year out here I hear people *b-wordin' and moanin' about how they four-cornered their snogo motor using Wiseco. All they had to do was warm the machine first. Usually drunk, they start the sled and rip WOT.

Wiseco are lighter though, make your sled sound like an F1 machine.

If Wiseco started producing them for saws, I'd by their pistons in a heartbeat.
