Bob Selman Designs Prop Adapters for GWS 4mm Bore Props

I've posted this info in a couple of different threads. But, since it's a very useful new product I thought I'd start a thread.

Bob has molded prop adapters that adapt the popular 4mm bore GWS props to 1mm, 1.5mm, and 0.046 inch shafts. Two of each are included, plus a couple of molded control horns.

These are not on Bob's site yet, but probably will be soon. So, if you want some now you need to email or call Bob Selman Designs.

The picture below is an early prototype before the control horns were added.

That's a great idea, now I don't have to use several pieces of hotshrink tubing to beef up thin shafts!

I don't know what the price is. Whatever it is it will be reasonable and worth it. Bob will know the price.

I do have these in stock. It is a tree with 6 adapters, 2 each of 1 mm id, 0.047 inch id and 1.5mm id. The od is a press fit into the 4mm id of the GWS props. At this time we do not have the horns that Gordon mentioned. That was the plan but we ran out of time. I'm charging $4 for a set of 6 prop adapters.

I just ordered some, thanks again for providing 'just what the Dr. ordered' , just when we needed it.

I also just realized that these adapters might also be useful as hubs for homemade CF props if the plastic is not to 'rubbery'.

The adapters are not "rubbery." They are made from ABS plastic, I believe, so they could be made into prop hubs for homemade props.

i am in the injecton molding work and was wondering what style
machine you used to make all your molded parts?

im used to running the industrial size ones that cost about $150,000 and up.
the molds alone are about 30,000.
so did you find a smaller machine than the ones im used to running?

Yes, we are using a small injection machine that was designed by Gary Jones. He also does the mold designs for me and some for Kenway.
