Thanks everybody for the comments!
Well the new motor arrived and i installed it.
New and the old

Modified delrin

Installed in the tube
Turns out i messed up in planning this boom. The second and third stage move at the same speed as you can see in the video put up earlier. I had planned on having one move faster then the other but i think im just gonna try and live with it for now. The new motor works like a champ and im very happy with it. That is all for now.
Next step will be the boom lift cylinders which will take 2 more geared motors and some figuring out. Thanks for looking. Let me know what you think!
