Electric starter Insert for 1/2A Question

Eric,
Any chance you have a digital caliper? A measurement of the aluminum cone inside diameter and depth would be good for comparison purposes. The Hornet IS a great 1/2A starter BTW.

I use the big model .15 .60 engine from hangar 9 i just flip the existing insert is a smal hole on the other side its Not Perfect but work

Here you go!

The Hornet starter is great. I use a regular starter for everything. I have made acorn nuts out of 3/8" and mostly 3/4" hex for all my motors. I had to make an insert to fit inside a regular cone. I just used vacuum hose from a car and glued it with the polyurethane glue. To get the taper inside I used a die grinder with a porcupine bit while the starter was running to get it to run true. It has worked well for over 20 years, but the rubber is getting a bit sticky now. I just give a quick blips to start if needed after flipping unsuccessfully for 20 times by hand.

Eric,

If you have a die-grinder, then do to the other side what ASpeed inidcates. A hard 90 degree corner will chew though the spinner as you see on mine above (cut a groove...it came to me this way).

My drawing shows the inner taper-cone, but only lists the diameter. The cone funnels in at about 45 degrees, thus increasing area of cone to spinner. This will increase the bite the starter has on these wee little engines...but it also decreases wear and tear on the spinner. You've got a hefty starter which can break our little guys in a blink. I don't think I need to mention "go lightly."

I also listed the shaft size, just in case you want to make a starter using Hornet bits, or even access a buddy with a machine shop.
