Dealing with a stuck hydro cylinder pin. Is this a good plan.

Have a 1" x prob 8"L pin that needs to come out. Due to a few reasons being hydraulic lines I can't move, and equipment onsite, I can't really run for the welder and hot knife. If you can imagine the 1" hydraulic rod with 1" eye on it, centered between two bossed which are each about 3" long. The issue here is getting compounded because I think one of those bosses is tweaked from hitting something. Like there is a chance that pin is bent! With that variable, I think I want to run a thin cut off wheel on each side of that cylinder eye, get the eye and cylinder out of there, which leaves me two pieces to extract, but half the war, maybe? Once the rod eye is out, there will be about 1.5" between those bosses. I don't have a plan on how to get the slugs out yet, but I figure if that pin is bent, this should help. Those big heavy bosses are only supported by 1/4" plate, like a box section, so it limits a few things, but maybe opens other possibilities.

Matter of fact, I cranked the Ace valve on the torch body to the max to see what's up, literally no flame change after about 1/4 turn. The sound is what was bothering me. It sounded lazy, not the hiss of business. IDK, maybe every other torch I've run were running big boy stuff and I am more used to that. But I probably can't say **** until I tossed in a new tip! I didn't have one and wish I had more time to play. Click to expand... Wonder if the O-rings need changing or something? Did you have the oxygen valve on the torch all the way open? It should be fully opened when using the cutting attachment and you use the valve on the cutting attachment to adjust oxygen. If the torch valve isn't fully open would restrict oxygen flow, especially when you need it for the preheat flames and the cutting jet. Other thought is the regulators have issues or the gauges read wrong.
