Mounting the PIAB Suction Cup

[MrForbes]

I have a lathe, I don't see what the problem is. Cut some threads in a piece of metal to fit the part. I guess if you don't have a lathe, then you see the problem differently than I do.

If the 3/8 NPT tap happens to have the same thread pitch, and the conical tap happens to have the same diameter as the suction cup at some point along it's length, you might consider making a thin nut from 1/4" aluminum stock. The threads will not be a perfect fit, but they could be close enough.

Well, until you know for certain where it will be placed you can just use a hot glue gun to make a nice seal. Once the suction cup is in place and you are certain of its placement you can use more permanent epoxy like JB weld.

No luck. That's our problem: There are no lathes here. (A excellent suggestion though, for whenever we do get one!)

...and I hate to ask a sponsor to spend big bucks to have one of their machinsts go out and make one lousy nut. That's one expensive nut!

Is that what your team is doing?


Other tricks, anyone?

(And before anyone says it, considering the thought time spent on this already I probably could have just gone out and bought the darn tap... But this is one of those "generic" problems that nag at you. I'd really like to find a better, simple solution for one-of problems like this than "go and throw money", just for the next time something similar comes up. Thanks!)
