This cylinder toast?

[Yotaismygame]

This will be a saw I’m selling. Had a lot of transfer on it. Ended up sanding through the platting on the bottom of the port. I’m thinking it’s done for. What do you think?

Those look deep. And they are to far down to say porting will remove them.

But im no expert. So don’t listen to me.

Talking about the worn off platting. Few scratches you can feel but will be fine.

 

[alexcagle]

Minor damage like that, under the port on exhaust side isn't going to affect much.
Run it.
Use a dremel 503 on the remaining ugly lines in a circular motion to try to clean it up a tad more.

Probably OK. I’d hit any edges that are proud with a diamond ball and then hand sanding.

How does it look above the exhaust roof?

I’d obviously let the buyer know before the sale as well.

Looks pristine from here. If rings are good you shouldn’t see any loss of compression.

What were you using to remove the transfer?

I'm still a fan of using acid if there is no scores through the plating then hand sanding with wet/dry after that. Using powered stuff can remove more than you need.

If you use acid, hand sand first with wet/dry and detergent. You have to remove all oils for acid to do it's thing on aluminum transfer

It will run fine. As far as selling, full disclosure with pic is the right path.

I started with sanding but got nervous about the platting so I switched to acid. But then got a little impatient and did more sanding. I still have just a little more transfer to remove about the port otherwise it’s good to go.

 

[Yotaismygame]

Also I will be porting and machining this cylinder. Does that change anyone’s mind?

Be careful with acid anywhere near the ports/edge of plating and any scores through the plating; it can eat underneath good plating. Have water w/baking soda for splashes/mistakes

PS. if you put a film of grease on the port chamfers, with a q-tip, the acid won't be able to hurt things, same deep scores.

Silk purse out of a sow's ear?

Might be good for practice or trying different mods.

Would you want to spend a lot of time on it for a saw you wanted to last?

Let us know how it lasts. It might surprise us.

Yes I’m worried about spending time on a less than perfect cylinder. But everything is good and smooth. I’m leaning towards finding another cylinder

Since this is going to be a customer's saw, I'd find another jug. That small chip out of the plating below and to the right side
of the exhaust port will likely be problematic. If your guy was ever to push the saw hard with a dull chain or put it into a hard
service scenario like milling or stumping, that area could lose more plating. If it didn't have that one chip in it, then I would
have said you're good to go.

There's no chipping at all. Just sanded off platting. I'm going to source another cylinder. I'm thinking if it's questionable I should replace it.

 

[Mad Professor]

One thought?

Would this not be a good test cylinder for porting?

That might run like a raped ape until it detonated. Issue there is rest of the saw when the grenade blows....

What does that cylinder belong on, make of saw?

Thanks, for a heavy saw like that along with porting I think you best find another cylinder. There is plenty of them still around. Fro just a runner if you were doing it to keep for yourself then it would run for a while yet.

Might make someone mad if you sell it on a saw but if you're gonna use it, I've seen worse...
