How To Remove Aluminum Transfer Without Acid

[Mastermind]

Excellent thread! Thank you, I'll be trying this out next week.

Just be careful around the edges of the ports. Good luck with it sir.

Thanks, Will do. I fabricate one-off's from aluminum and cres for my day job. I spend hours a day with a 1/4" burr motor, roloc's, scotchbrite, etc. so this will be a familiar task.

Got after it tonight, I think it went pretty well for my first time. Port edges look fine, except for one spot on the exhaust side that may have been a casting flaw or damaged when the ring came apart. I can see it well through the plug hole and the plating looks intact. It isn't raised or deformed inside the cylinder. Ok to run?
I started with 120, then 180 and 240 grit. Finished it with a good buffing with green scotchbrite on the roloc holder.
Thanks for everyone's help so far.

Use a small diamond ball to bevel that spot......sand it with 220, and run it.

This what you're talking about?

Like this? or does it need more bevel?

 

[Mastermind]

That will work.

Not a very good pic but there was some heavy transfer in this jug

Transfer was the heaviest on each side of the ex port. I ended up taking some of the plating off as you can see here

Guy was gunna get em sent out and re-nikasiled. So if I could save it's a plus but there was too much on there. Lots of port edges in that area.

 

[Deets066]

Would it last like that?

 

[Mastermind]

I think it would.

As long as the plating ain't trying to peel.

I'm pretty sure that would be OK to run. If nothing else it'll get him to his next rebuild.

Not at all it was hard as hell, the plating isn't gone completely like it looks in the pic. Just around the edges of the ports

What is the cost of re -plating one do you know?

 

[Deets066]

I don't think an open cylinder is too bad

I thought I would dig up this thread since today I tried the @Mastermind method of transfer removal for the first time. I have a bunch of carcasses here that I have been rebuilding and I have a few cylinders that I would like to save. So first up was a Husky 154se cylinder that had transfer on the exhaust side that looked like it might clean up okay. I followed the steps Randy laid out and when I was finished, I was truly amazed. Once finished with the scotchbrite the cylinder literally looked new again. Wow! I was so impressed that I grabbed a real nasty looking Jonsered 630 cylinder and gave it a go. Again, the cylinder looked amazing - almost like new.

Thank you Randy for this great tutorial! I salvaged 1 hard to find cylinder, and one that I thought was a goner.

You're very welcome. Ol Scott Kunz mentioned that he sanded the transfer off years ago.....and I gave it a try. So gotta give the real credit to that fella.

Scott sure is one fart smeller.
