I like to cut them from homemade fiberglass sheet. Just laminate several layers of glass cloth with epoxy or polyester resin between a couple of pieces of waxed window glass to form the sheet. If you're in a hurry, a laminate of fiberglass cloth / medium CA also works, but is much harder to shape. Wax may or may not work as a release agent for CA, so use plastic sheet or waxed paper between the laminate and the window glass. If surface finish of the fiberglass sheet isn't important, you can use any two flat surfaces with a plastic sheet / waxed paper release agent as your tooling.

Many good ideas but I think I like the Flossers the best due to simple fact that they give a wider area to glue to at contact to foam and are at an aceptable angle as is. Use one as a guide to drill holes and you will have nice even spacing. Time for a trip to the dollar store on the way home.

"..And who doesn't have some old plastic props lying around?!..."

If there is someone that needs some help on breaking props, I can help with that. PM and and I'll send you a list of the sizes I specialize in breaking and you can send them to me.

I'll need to charge you for return postage too.

I make control horns from CD plastic. Using rubber cement I paste a guide template on a defunct CD. Then I just follow the cut lines with an Exacto saw or small electric model circular saw. By using the template I can make many control horns having the same dimensions. For added strength I sometimes stick transparent scotch tape over the control horn surfaces.

Flosser

Thanks for the tip on flossers, I am trying it. The plastic seems soft when I drilled it. Does the hole get worn out (oblong shape) quickly? I guess I will find out. I wonder if the brand name flossers have harder plastic?

I've been using them for the past few years without any problems with them. YMMV

You can cut them by hand, but at eight/one dollar I just grab a pack now and then and keep 'em ready. They may fool you and look flimsy if you flex the whole board they come on but break them out and in their singular self are very strong and stiff.
Where do you get these?

I wouln't use CDs, they are made out of quite brittle plastic. And i know a guy that used them on a 3m thermal glider once... Guess what happened?

I usually just buy the horns, they cost about $1 for 10 pieces at HK.
