New to me Duplex nibbler

[FlyingLow]

So today I stopped at a flea market I drive past every day to work in Yale BC. If you've been through there you know what I'm talking about. Anyway found a Duplex Tools nibbler type N10A for $15, it runs so I figured that was a good start. Brought it to work and hosed it down to clean it up, has a couple issues but can't find any information on it. It is rated to 10 gauge mild steel which I figured is pretty good, I don't tend to work with anything in that range, more 14 and 16 gauge or 3/16 and 1/4". Any info would be appreciated, pictures are coming, just give me a few minutes.

Pictures. So issues are the plug which I made the guy plug in to see if it worked, the mandrel (?) I'm pointing the screwdriver at and the aluminum lug that's broken off. The cutting edge of the mandrel is pretty worn and I'd like to know where to find parts. I wasn't able to come up with anything on google. Thanks.

Here's a picture of the mandrel or I guess die is more appropriate. If anyone knows anything about it please let me know.

You can make that out of tool,steel and harden it if you can't find one

The piece you're referring to is usually called the die, and the movable cutter that punches the metal is referred to as the punch.

I had never heard of Duplex, but it looks like they were a British company based in Tipton, West Midlands. It also sounds like they're now defunct.

This company seams to have sold Duplex nibblers. Your model isn't listed, but a model N10K is. If Duplex was like some other companies that make nibblers, the dies and punches from later models may fit earlier models. The description also says the dies and punches were made to be resharpenable on a regular grinding wheel, and that the manual has a description on how to do so.

Yeah I was thinking about that, I contacted my machinist buddy, he doesn't sound keen but it could be my last resort. Or maybe weld a piece on and machine it? It looks cast though, not sure about welding it.

I am hoping the die is interchangeable, I don't see how it can be resharpened without adding material.

Thanks guys.

The end of the punch can be ground to resharpen it.
The top,surface of the die can be ground to resharpen it but that one is beyond that

If,it was me I would get a piece of round stock tool steel
I would mill the profile,shape and then slice up,several of the dies and harden them
Then you have several,for the future

So just an update, I found the dies available at KBC Tools and bought 2 so I have a spare. They are exactly the same as the original. Thanks.

better check your numbers

I have, I meant either thinner or thicker than 10 gauge. Won't feed 1/4" into the nibbler (don't think the throat will allow it if I tried).

Do you still need a punch or die? If so let me know, my father owns the company.

Many thanks
