1/2-20 UNF adapter for Benjamin discovery?
« on: August 18, 2016, 03:39:33 PM »
Anyone know where to get one of these besides Discosrus or on eBay? Norms getting out of the business and the one on eBay comes from Serbia and 2-4 week wait. Or anyone with any experience with a different LDC on a disco than a TKO? Never been a fan of the looks with CF and I have 2 discos with BNMs and want something different but effective for this one.

Look up a local Machine Shop.  Call around and find one that will do small work.

Josh I have been talking to Norm to confirm these guns are really 3000psi capable so I did just ask him if he happens to have any even though his sight says out of stock. We'll see what he says.

Tim I will definitely look into that if I can't find a source for one that's premade.

The Disco is a 2000 psi gun as manufactured by Crosman.... I use it up to 3000 psi IF AND ONLY IF the valve screws are replaced PROPERLY with 10-32 high tensile, low-profile socket head set screws.... That involves rethreading the three holes in the valve.... While I wouldn't do that if I didn't consider it safe, you accept full and complete responsibility if you use the gun in a manner not recommended by Crosman.... The stock screws have been shown to fail (the heads shear off) at the equivalent of 7000 psi, which using the ASME standard safety factor of 3.5:1 to failure means that Crosman's original recommendation is right on....

If Norm doesn't have any left order the one from Serbia.  Anybody with a lathe and a mill can make one, but the time to make just one part is not worth it for anybody unless they just want to do it for fun.  If they had a market for a dozen at a time it might be different.  If you have a neighbor who likes to tinker in his home machine shop, and don't mind aluminum in its raw state maybe you can trade services for something you can do.

Thanks Bob. One is Manny's daughters rifle that Nor. worked on and did valve screw upgrade himself and the other is using a DPV from Norm which come tapped for the bigger screws. I've sent pics and everything to him already to confirm. Sorry I didn't make that clear for others with discos.

I'm going to see what Norm says about it and then if not I'll order the one from Serbia. This is going to be a slow project gun so won't kill me to wait

Might also check with Baker Airguns.  They seem to have a lot of stuff for Discos.

Got this from the Paris D LDC website.  Supposed to be for a 1/2 20 UNF adapter.
