Morning, Chaps, well I tried the " Wood & Sledge Hammer" method, and only succeeded in shattering the wood, without even slightly moving either Piston ! ! .
Time to get angry šŸ˜” so I found a suitable piece of thick plate, and a nice longish piece of Bronze Bar, and then gave the "Buggers" what for.
Even then, it still took some time to persuade them to give in, once removed, I used my faithful home made Honing tool( A piece of circa 3X3 wood) that had been shaped to fit the Bore, but with a "Flat" on either side with a home made spindle fitted. and a suitable piece of "Wet & Dry" paper secured with some Drawing Pins, and the proceeded to "Hone" the Bores,using my electric Drill.
Surprise,surprise, they cleaned up remarkably well! , which is more than I can say for the Pistons( I'll take some piccys later)
So now what to do now I ask?? Thought about asking, if any of you out there had a good set of " used + 0.20" Pistons as the Bores look very good as do the Big End & Mains, I could then rebuild the Engine and store it .
What does the team think?
More later.....

Cheers A'l :D :D

Get the block thoroughly cleaned and then painted silver-grey, add some short legs at the bottom, a sheet of plate glass on the top and turn it into a coffee table and put it in the lounge! Maybe use the pistons upside down as the legs and weld or bolt them to the block.

You can see, the state of the Two Piston's that were seized in the Bores, at the moment, the Gudgeon Pins are also seized in the Pistons. L@@ks like more "gentle persuasion " is going to be needed !!

Hi, well, I managed to Drill out all 6 broken off Studs and re-tap the 3/8 BSF threads successfully, so now need to get some replacement Studs turned up, to finish the job off.

Cheers A'l :D :lol:

I have this issue with sleeve valve motors , I tried every thing soaking in diesel for months , I tired shaking it - burnt out two orbital sanders, a bankable quantity of money on specialised liquids etc
the way I succeeded was to place ice into the bore - froze some plastic bottles, placed ice inside the piston and let sit for 15 minutes and placed twin 500 watt heat lamps on each side of the motor - most successful and on more than one occasion,
cheers
