I don't watch football, so I'm updating. sigh. It's been a trying day.
I didn't have a proper pin wrench to torque the piston off, so I had to make one. I had a pickle fork (for busting apart suspension ball and sockets in automobiles) that I wasn't using, so decided to use that... I just pressed in a couple pins without glue or anything, so I can take it apart and use it later:
Next, I had to make a holding fixture for the group. I used a scrap piece of wood:
I then had to make something to slip into the springs; it had to be rather slim, but strong enough to press the spring down. I had an old handle for a clutch holding tool I had made for an old motorcycle that I didn't own anymore, so I cut this up:
It was a single piece, which I cut in two. Then drilled a couple holes for a couple small hinge plates so it could be folded around the shaft in between a couple of the spring coils. I reasoned I'd just hold the other end closed with a zip tie, then press down on both ends of the metal sticking out from the coils. I rigged everything together, but could not use a press directly on one end because it might slip off and go BOING. I needed something that would not twist off... and pressed one side of the spring down with a small tool I had made earlier for reachign in and crushing rivents inside AK47 type weapons... the other side I pressed down with a large C clamp and prayed it would not slip off. The pressure was rather low, so didn't really alarm me too much.
There are probably much better ways of doing this, but what would life be if everyone was reasonable and everything was easy? Rube Goldberg is laughing uproariously somewhere.
Anyway, I got a little uncomfortable with how slipshod it was so quit and modified a couple large C clamps by drilling a hole into 1 jaw:
I got rid of the Rube Goldberg setup and moved it into a vice and used both C lamps on opposide sides of the spring to pull the spring down evenly. The holes in the C clamp jaw exactly matches the diameter of the bolt in the levers sticking out from the coil, so the C clamps can't slip off and loose their grip.
Tried to lock the shaft in padded vice jaws and twist... no go. Boy its on tight! No matter what I used, it slipped... must be a TON of threadlocker on it. I dragged out my gun barrel vice. You'll notice I didn't bother to cut exactly fitting bushings to grab the shaft; I just used bushings that were 'close enough' and figured I'd give it a shot. Kinda upset at this point and getting hungry for dinner.
Applied heat, and it GRUDGINGLY started coming off. Man was it tight. It's cooling off in the garage now...
