Need help on Rodzilla T-rex part

[Panama Evans]

I just purchased a T-Rex and yes it isn't hear yet, but I wanted to see if anyone out there had one so I could get the thread size of the joystick knob. I would like to get a custom one for mine, so it could be here before my rest shows up
Thank in advance for any help

The joystick knob is just a piece of plastic that slips over the shaft.

Awe thank you. Do have an idea of the shaft size? That way I could thread it and add a knob of my chosing

The shaft is 3/8th of an inch and sticks out from the edge of
the frame only four inches. You do need an extension. I would
wait until it arrives then set it up with your rifle to find what your
preferred length will be.....I made a custom one for myself using
a heavier wall aluminum tube and kept Rod's attachment piece.
Mine for comfort in it's use came out to be 17" long, and I just
used a stainless steel acorn nut for the knob.

Thank you for the info, and pic, that really helps. So heres a question, the acorn nut, is it threaded and if so what size threads?

 

[Fuj]

Yes, threaded on. 1/2-13

Cool that is what I needed. Thank you for your help. You're the best. Oh how do you like your t-rex, and any suggestions you might have. I was blessed to get one in like new condition for less than any I've seen on the forum. I hope to have it next week once the money order I sent for payment has cleared the bank, and 5 day shipping time.
