Re: Flats machined on COX cylinder top fin, for the wrench
I think you will find the steel is very mild strength , the main problem is holding it still to get an exact cut . I believe TexasWade has that taken care of for you ^^ For the leaking from the sleeve Mauricio Had mention in a post something about a dimple or the way he had to cut his homemade sleeves to make work properly I believe . Maybe he will chime in here

Re: Flats machined on COX cylinder top fin, for the wrench
Thanks, Eric,
unless I can follow the method TexasWade was proposing, i am thinking of carefully fixing the 09 crankcase in a vice (
), and screwing in the cylinder in the crankcase. For a mild force of filing the fin this should not require a strong grip in the vice which would be harmful for the crankcase. The backplate in the crankcase adds to its rigidity.

Thanks, Eric,
unless I can follow the method TexasWade was proposing, T am thinking of carefully fixing the 09 crankcase with one of its mounting lugs in a vice (
), and screwing in the cylinder in the crankcase. Then I will have the cylinder laid out horizontally, which is convenient for filing the vertically orientated fin.
For a mild force of filing the fin this should not require a strong grip in the vice which would be harmful for the crankcase nor its mounting lug. The backplate screwed in the crankcase adds to its rigidity to save the crankcase roundness too..

Just so that you are aware, I believe an English motor, maybe DC, recommended a strap wrench. They showed a drawing on it's construction that used a leather strap and a piece of wood for a handle. Pretty much like an oil filter wrench.

Re: Flats machined on COX cylinder top fin, for the wrench
Thanks, aspeed, many fellow CEF members have also tried the leather strap method on COX cylinders, but I think only only a few managed to use it as a reliable cylinder removal tool...I am among those who were not successful. No matter how well I degrease the cylinder fins, and how tight I try to wrap the strap around the cylinder, the lil bugger is just reluctant to budge...
