A friend of mine has an Ohlsson .60 sparkie that is worn out. This is one of those with the cylinder firmly spot welded into place in manufacture. One time (long before I saw this one) George Aldrich told me that he had worked out how to fix them. Does anyone out there know what it was that he did to bring them back to life? If so can you tell me.

Thanks in advance

Try sending a note to Don Blackburn, I believe he can do Ohlsson's.

He rebuilds engines for many of the old time free flight flyers and his work is excellant.

Thanks Don, (For the speedy reply) I will pass the message along, although I would like to know how the job is tackled and I would consider having a go myself.

I believe that Don, like many others, Chrome plates the piston and relaps it into the sleeve. I don't think that Don is on the internet so you will have to write him via snail mail. If I know Don, he will share his methods freely with you.

Charlie - there is also a fellow in the Buffalo, NY area who, I believe, specializes in O&R. His name is Victor Didelot and I found his name through MECA. Hope this helps.

I've often wondered on a situation like this if there was enough meat in the piston, why not just cut it for a standard size ring?

Eric - the ports of the O&R (at least the one I have) are not "webbed" to confine the ring. It will just pop out and get very messy!

To quote the "other" famous Homer, "Doh!"

Yeah, as you can see, I don't know Ohlssons well. A lot of engines had a center post in the exhaust to mount the butterfly. Not sure if that would be enough support, but it might.
Oh well, it was just a thought. I was thinking it would be one way to restore some of these old whipped engines...

Gentlemen: I have had some excellent engine work done by Don Blackburn. As far as the O&R 60, you might also contact

George can replace cylinder gaskets and spot-welds.
