Cylinder coatings

[romeo]

Will black anodizing a cylinder be as good as chroming? I only ask because I have a black anodizing system here. Has anyone tried this????

 

[Reddog]

you can try it. But it is alot rougher than chrome and not as hard.

 

[bwalker]

Anodizing is next to useless as a cylinder coating.

Its just gonna wear off and cause one dirty arse crankcase.

Its just gonna wear off and cause one dirty arse crankcase.

And the anodizing wil destroy the bearings...

Idea has been SCRAPPED. Their will be no anodizing today. Thanks for the info.

chrome plating

On a similar note, Caswel Inc sells chrome plating kits. http://www.caswellplating.com/ I've used their electroless nickel kit to nickel plate firearms and they work quite well and do a decent job. (Because I mixed a large batch to do a few firearms at once I did have to get a $20 aquarium heater at Walmart, remove the governor on it, and use that heater as a suplement to the included heater to get the plating solution to the proper temperature.)

I haven't tried it on a chainsaw cylinder, but I imagine as long as the prep work is done correctly and the surface of the cylinder is properly pickled and degreased, it should do a decent job.

A couple of stupid questions Sap: Will that kit just plate the cyl. or the whole head?
A govener on a fish tank heater? What the? I am a fish neophyte, please explain that to me? ( you can send me a PM as to not hijack the thread)
Thank you, good post BTW, welcome back,

Good post Sap. Lot of good information there. I have no clue whether that plating would work on cylinders or not but on guns nickle plating is beautifull. Glad to see your back. Everyone was asking where did you go. Notice the avitar Sap, its been changed to stop poking fun at you, it now pokes fun at me. Might be a good time to change yours too. Regardless its good to see you back.

huh? To put this on the inside INSIDE of a cylinder, you first would need to machine out the old coating, hone, pickle etc etc... and with a real machine shop, not a home hone on a power drill. If you are going to all that trouble, get it professionally plated with nikersil, or, if it a modern saw it's likely cheaper buy a new cylinder. I don't see any motorcycle guys plating their own cylinders...

My fish tank heater is adjustable and will heat to 200 degrees if you like your fish boiled.

You must be at altitude... mine boil at about 212

I am full of supid questions today, please bear with me.
Nickle plating usually adds .005" to the thickness, giving you a .010" smaller bore. How tight is the piston fit on a typical chainsaw Andy?

depends, but .5 to 1 (thou inch) on a small bore saw is what I see. You really thinking of plating a bore with nickel (I wouldn't)? You can't plate without boring and honing first (chrome). Quality of finish is critical.

Read up on the motor cycle / snowmobiles / jet ski etc forums about boring and re-plating - those guys are all over the issues.

What saw are you thinking of doing this on?

 

[coveredinsap]

To answer the question about the aquarium heater 'governor'...if you remove the limiter cap on the heater thermostat you can turn it way up.

As for the coating thickness...I let the electroless nickel plate for about 45 minutes at temperature and it didn't effect the screws threading into the firearm (the electroless process coats everything).

If you electroplate you have more control over where the layer is deposited.

I read of people around here salvaging cylinders with hand sanding. Putting a thin coating of chrome with a electroless or electroplate chrome kit is not cost effective how?

Read the Caswell site. People plate all sorts of things with their kits. And you'd never know the difference.

The questions is: What does it take to get a coating on a chainsaw cylinder depending on what the cylinder is made of....and you'd have to read the Caswell site for that information.

The chrome plating in the two stroke bores is a hard chrome. Its a whole different process than what is used for show or to protect something from the elements.

 

[LarryTheCableGuy]

Chromal has been doing hard chrome on cylinders for a good number of years (20 years+? I don't remember exactly).

They know the RIGHT way to do it.

I had this conversation before with a guy who was pimping his brother-in-laws "hard chrome" plating service at his gun shop. It's bs. The Caswell kits are as good as anyone's....the plating process is the same whether it's done by a 'pro' or not, and these kits are the same thing too.

It's a chainsaw for christ's sake.

Here's one of the Caswell 'hard chrome' kits:

Here's the electroless 'chrome' kit (actually nickel and cobalt)
