This is real crucial to me repairing my Ross drive.

Chuck, did you try to drill out the pin? Or at least drill

a hole down through

it and then try to press it out?

(C.D.) No I did not try that. If I can get around to it I will try and let
you know.

Did you first grind off the "lip" from the sun gear

securing the pin?

(CD) Yes, I used a Dremel tool to grind off the peen or swedge, whatever
it's called

If I can't get the pin out and press off the old sun gear

I'll have a real

mess on my hands. According to Tracy, Ross ground off the

old sun gear when he

replaced the sun gear on Tracy's Ross drive.

Attached is a picture of a saddle block I machined out of aluminum to hold
the shaft while pressing the pin. It could also be used to drill out the
pin. Finn, if you want to use it, I could ship it to you. Of course every
Ross seems different and it may not fit yours. My shaft diameter at the pin
is 1.750"

>From what I've seen our drives are quite alike. However, my teeth area is about 1
1/8" long. My pin is 2 1/8" back from the front of the sun gear. Yours look a lot
closer. Ground down sun gear OD is also 1.75" on mine.

Thanks for your offer of shipping it to me, but I'm going to try to get it out
this weekend. On the other hand, I just got my prop back, and I'm very tempted to
bolt everything back together and go fly, if only for a couple of hours.

Must be a cultural thing. This risk taking :-)
