Nick,

Try Ned Schmidt here on the forums. He made a couple for me a few years back when I was building micros.

Take care,
John

Thanks John but there is no one by that name listed in the "members"

[johnnyoverkill]

Sorry Nick, he's listed under N.H. Schmidt.

Tell the old buzzard I said hi!

Freebie!

I will make you one. Aluminum, tapped for 6-32 set screws, two per end opposed to each other (thru tapped), you want 5/16 or 1/2" aluminum?

I need OAL and how deep the larger diameter needs to be. I think I can make it Monday, might be tuesday and I will mail it out to you.

I just made one on Friday, .093 flex to 2.26mm motor (2632 mystery)

what do you have with a 2.3mm shaft that is not the motor?

OK here you can see the 1/8" shaft on the motor and the 2.3mm prop shaft...you can also see the coupler that came with the prop shaft it had 2.3mm on both ends but I tried to drill one end out to 3.2mm but ruined it...the coupler you see here is about 15/16" long and has a 9/32" diameter

Nick,

If you and Brian don't get it worked out, you can find Ned as the first listing under the letter "N" in the members list.

Good luck either way!

The 6-32 wasn't a quantity, it's the size. Quantity was four - 2 on each end drilled through. And that is a good arrangement. You'll want at least 2 screws on each end to be able to balance the coupler to minimize vibration. I usually ask for three (spaced 120 degrees apart) when the application is a jet drive. Jeff Wohlt does a bangup job on these, I've had several made up for me in the past.
