It's really taking shape. The bearing you're using for the boom will certainly be up to the job! It's massive!

Re: Aeromax Rotating Wrecker
 

Thanks snowman! If its not up to the job then something is really wrong! haha

Well finally did some more work and moving forward on the boom! Heres some pics
First a made a motor mount out of delrin

Re: Aeromax Rotating Wrecker
 

Really tidy screw drive setup there!

Re: Aeromax Rotating Wrecker
 

Thanks guys. I did some testing today and found that the little copal 60 motor has just enough power to move one section of boom very slow. Dont think its gonna have enough for 2 sections. Any suggestions for more power and speed motors in the same small size? Id like to try and stay away from 12v motors if possible. Thanks again
Scott

Re: Aeromax Rotating Wrecker
 

Sorry to hear your having problems with the motor,I looked around on robotmarket place didn't see any over 50 to 70 oz of torque for the copal motor,what is the ID of the square tubing,would something like this motor work,may be to big though.Diameter is 21.8 mm ,works on 6v and 12v

Re: Aeromax Rotating Wrecker
 

Looks great so far. is the boom going to telescope?

Re: Aeromax Rotating Wrecker
 

i would roll my knight hauler just to see it work! j/k but maybe have a fake breakdown! sweet truck you cant put it together fast enough for me!

Re: Aeromax Rotating Wrecker
 

Thanks Cowboy!
Brian, yes the boom will telescope as u will see in this post!
Demond, we can arrange that for sure! haha
Ok did some work today and a good bit at that imo.
This is delrin drilled and tapped in the second section of boom that will telescope

The lamp rod (threaded rod with the center drilled out) Holds the motor on one end and has delrin in the other drilled and tapped to move the third boom stage

This is the third stage which is the final stage delrin tapped and jam nutted to make it move.

Re: Aeromax Rotating Wrecker
 

I then made a little test video after assembly. The boom still needs to be adjusted but im waiting for the new drive motor to arrive.

Then i managed to drill and bolt the boom in place on the boom base and am finally starting to make some head way on this thing.

These are with the second stage section in

Hope the video turns out alright.
Thanks for all the compliments guys and gals. It really helps keep me motivated to push forward! Let me know what you think

Re: Aeromax Rotating Wrecker
 

Made a video this morning to test the rotation unit under the weight of the assembled boom.
http://www.youtube.com/watch?v=M46uI...1&feature=plcp

Works great in my opinion. Also took another pic before the video haha

Let me know what you think! Thanks for looking

Re: Aeromax Rotating Wrecker
 

Great work, well impressed man!

Re: Aeromax Rotating Wrecker
 

Hi Scott. What are the OD and ID of the 3 tubes you are using for the boom?
Thanks!
Doug

Re: Aeromax Rotating Wrecker
 

I like the capped off side skirts!

Re: Aeromax Rotating Wrecker
 

Great job!!! The video is great too, the rotator works nicely

Re: Aeromax Rotating Wrecker
 

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!
