    a screw fell into the press and put a nice little dent in the impression cylinder. How can I fix this? Not deep.

    Jb weld it works great dries fast and can be filed down so it's smooth to the surface

    I ran a 5c Komori where the previous operator dropped a allen wrench into the imp cyl on #4. It put a Nike shaped impression into the cyl LOL. I used Marine Tex to fix the damage. 2 part epoxy and a bit tougher than JB weld and the likes. I taped off the section on the cyl with masking tape. Used a little fine sandpaper to "tooth" prep the surface, mixed it up and spread it on. Let it sit up for 24 hrs then lightly sanded till level. I ran the press for 5 more years like that till I changed jobs and was still going strong. I guess try a few and see which one works the best for you. Not the best fix but inexpensive, yes.

    I totally agree with the jb weld. I'm currently running an 02 in my garage that I had to fix an allen wrench shaped mark in the impression cylinder (not from me....the previous owner.) However, when I was at training for repairing ryobi's a few years back, this subject was brought up. JB weld works great, however, sometimes it can "pop" out and then cause a smash elsewhere in the cylinder. Just something to think about. I think the bondo might be a better way to go, I've heard of a lot of guys doing that and I don't think it would hurt as bad if it ever came out. Just my $0.02.

    This may be a stupid suggestion but I don't know your press. We had the same thing happen on a web, the set screw nailed two towers on its way out. Not big but deep. We just lined up the dent with the blanket gap, on our press we can change timing, by moving plate and blanket cyl. No bondo no nothing. Still running this way.

    I wouldn't mess with the timing at all could really mess some things up with your feed/delivery jb weld wont pop out if you prep your surface the correct way.

    Changing timing on this press to match gaps and what not is a no go on these presses. You will have more issues than just a dent in the impression cylinder if you do that. Just fill your dent and you'll never know it was even there.

    you can have it professionally repaired where the work is guaranteed to last forever. Don't remember the name of the guy we used i think we found him in the back of a trade publication. If you don't want to spring for a professional repair the epoxy thing works pretty good. I too make a point of roughing up the surface around the smash and use a 2 part epoxy to build it up not only in the smashed area but with a half inch all around it. Try to perform the repair on a friday so you can let the epoxy cure over the weekend. Then first thing monday morning just sand it down to match the contours of your cylinder. Patience pays off big when making this sorta repair. Good luck
