HI:
MAY BE YOU THOUGHT I WAS POSTING THE RIGHT WAY TO SEAL THOSE NASTY SLOTS IN CILYNDER, I wish i could!!

Instead, I´m asking a way to seal them. I saw a post here when somebody was about to "plug them" from the outside, but want to know if anybody have some knowledge about the pros and cons of this method or if would exist some tested procedure for that.

Please do not tell me to go to ebay, outdoordistributors or harborfreight, that would be the easy way, and since now a friend "remembered" he has no one, but two!!! lathes in the backyard at home...my engines are crying for some internal improvement.
If there is no way to acomplish this safely. i would try simply find out and buy those old cylinders with out the slots, but seems hard to find, don´t you think.

Tatolazo.
