Had a small set scew back out and fall into cylinder. Luckily only got pressed once.Heard there is an epoxy that I can use to fix thread marks. Can anyone point me to where I can find this item?

smikes,

I know this is going ot sound rather hillbilly, but JB-weld might work for you. You can get it at any hardware store.

I used to run a 4-color Akiyama Hi-Ace that had a nice dent in the first impression cyclinder matching the shape of a lock washer. The previous operator/owner tried to fix it with JB-Weld but did not take the time to sand the JB down to match the curve of the cylinder. I spent a full day sanding and polishing and running test prints on it before it became acceptable enough to print large areas of solid color on lightweight stock with no visible evidence of the damage on the press sheet.

I ran the press for about 4.5 to 5 years with no problems caused by this repair.

Like I stated earlier, it sounds like a hillbilly technique but....it worked.

Jason,
What did you use for sanding? Grit wise? Block sand with wet automotive paper? Thanks for any pointers you can gine me!

smikes,

I used a dry sand paper at first, about 300 grit. Make sure to keep the paper off the impression cylinder as much as possible. Then I moved to block sanding with a 600 grit wet paper while doing test prints. THEN moved up to a higher grit wet paper (900 or 1000, I can't remember). THEN polished it, again while doing test prints.

Maybe try this on some curved scrap metal first if you've never done any kind of automotive body work before. I could end up being a lot more work than is needed if you aren't careful.

Sorry it took so long for me to reply, I hope it works out for you.

Jason

Thanks for the reply, as of now I have been working around the area and haven't needed to do anything to it yet. Was thinking about cutting a small window in a thin plate and taking the slight bulge area down with one or two light strokes with a file. Then filling with the JB and sanding thereafter.

What ever you'll do you'll would not be able to get it to the original condition.

My idea is to get the cylinder grind by few micro mm and to use more packing for the jacket/blanket and to adjust the pressure between them.

I do not know whether you'll could get the cylinder grinded in your countries, but we can get it done in Sri Lanka
