Starrett 818 Center Punch Fix?

[lbperry]

I have a Starrett Automatic Center Punch that started becoming very erratic about firing. Sometimes I had to press 3-4 times before it would fire.
I got an exploded drawing w/parts list, disassembled the punch, cleaned it up, lubricated it with some light oil, and reassembled it. Started out like it was gonna work fine but quickly returned to its old ways.
From the parts list it appears that either the trip pin or the punch would be the suspect parts but before I just start throwing parts at it, is there anyone out there that is familiar with the problem and can guide my attempt at fixing it?
Thanks,

Posted this over 2 months ago and got NO replies. That's extremely unusual for this form. Anybody know anything about fixing a Starrett automatic center punch?
Maybe I need to ping a woodworker or carpenter forum?
Thanks

Bump, I have the same model, same problem. I suspected it was the spring or trip pin.

These guys like photos and links, add that and youll get some hits.

ps. have you found a link to buy parts?

Got a couple of links that give an exploded parts diagram and a parts list:

Wasn't sure just what to order so I haven't found a place to order them from.
Youtube vid was interesting but didn't give me enough clues on how to fix mine.
Thanks for the replies. Keep 'em coming.
Thanks

Send it back to Starrett and they will re-build it for free.

I use Starret punches at work. The trip pin spring is what generally breaks on the ones I use. I ordered some from Starret. They are easy to install and get the tool back in
action.
