Aeromax Rotating Wrecker
 

Hello all. Thought i would share my build here. Hope you enjoy!
This is what im basing my model off of. Its a Century 1075s rotator.
http://i99.photobucket.com/albums/l2...8LngSiQ_12.gif
Started with a stock aeromax and 30 inch rails
http://i99.photobucket.com/albums/l2...d/IMG_0014.jpg
Added lift axle
http://i99.photobucket.com/albums/l2...d/IMG_0021.jpg
Removed sleeper and filled in back of cab
http://i99.photobucket.com/albums/l2...d/IMG_0025.jpg
http://i99.photobucket.com/albums/l2...d/IMG_0097.jpg
Made my first wrecker body on my first atempt at styrene
http://i99.photobucket.com/albums/l2...d/IMG_0114.jpg

Then the project went on hold for almost 2 years. Didnt have the time to mess with it...

Re: Aeromax Rotating Wrecker
 

Once i got back to it a month ago or so i started building the base of the boom and working to figure that out. I picked this tank turrett unit up for rotation hoping its strong enough to do the job
http://i99.photobucket.com/albums/l2...d/IMG_0089.jpg
And my first attempt at the base was unsuccessful
http://i99.photobucket.com/albums/l2...d/IMG_1006.jpg
Not strong enough
http://i99.photobucket.com/albums/l2...d/IMG_1007.jpg
Then i went down to my snow plow buddies shop and got this bearing
http://i99.photobucket.com/albums/l2...d/IMG_1010.jpg
And a one inch bolt i center drilled to hold all the wires in the middle of the rotation
http://i99.photobucket.com/albums/l2...d/IMG_1013.jpg
This is overkill but i like to work that way! haha
Then i cut a piece of thicker aluminum to fit the gear and mounted it to the chassis
http://i99.photobucket.com/albums/l2...d/IMG_1021.jpg
And it actually works haha. Surprised myself a little bit.
Then i started cutting and bending sheet metal to build the boom base.

Re: Aeromax Rotating Wrecker
 

Once i got that together it was time to mount the winches which is where im at now on this build
http://i99.photobucket.com/albums/l2...d/IMG_1086.jpg
http://i99.photobucket.com/albums/l2...d/IMG_1087.jpg
http://i99.photobucket.com/albums/l2...d/IMG_1088.jpg

Im hoping that the winches will be strong enough for this. Thats what i got so far.
I'll be ordering the aluminum tube in the next week or so to start fabricating the boom. Pics will follow as i get them. Thanks for looking!
Scott

Re: Aeromax Rotating Wrecker
 

Sweet build! Can't wait to see more!

Re: Aeromax Rotating Wrecker
 

Very nice. those turret rotation motors are actually one of the better parts of th HL brand of RC tanks. Strong enough to brake the gun barrel off of the tank if it gets hung up. the only real draw back is you do need to use a bearing support base like you did for your application.

Re: Aeromax Rotating Wrecker
 

Great start, hope the rest goes nice and smoothly for you!

Re: Aeromax Rotating Wrecker
 

Good looking build ,Scott ,great work so far,looking forward to seeing how you build the boom,keep the pics coming:D

Re: Aeromax Rotating Wrecker
 

Thanks guys. Im hoping it does to! Im never played with one of the tanks but barrel snapping sounds good to me! haha
Scott

Re: Aeromax Rotating Wrecker
 

Update. Boom aluminum tube ordered from McMaster Carr and Online Metal Store! Ordered sooner then i thought...
Scott

Re: Aeromax Rotating Wrecker
 

While waiting for the boom tube to come in i decided to try and keep some updates coming with what im working on. So today i was playing with some cosmetics while i wait.
Took the stock skirts and trimmed them
http://i99.photobucket.com/albums/l2...d/IMG_1089.jpg
http://i99.photobucket.com/albums/l2...d/IMG_1093.jpg
Cut some styrene to fill the gaps
http://i99.photobucket.com/albums/l2...d/IMG_1092.jpg
And comensed gluing
http://i99.photobucket.com/albums/l2...d/IMG_1095.jpg
And this is what i ended up with
http://i99.photobucket.com/albums/l2...d/IMG_1096.jpg
http://i99.photobucket.com/albums/l2...d/IMG_1094.jpg
http://i99.photobucket.com/albums/l2...d/IMG_1098.jpg
http://i99.photobucket.com/albums/l2...d/IMG_1097.jpg
Also worked out that i now have some space to hide a few of the many ESC's it will take to run this thing
http://i99.photobucket.com/albums/l2...d/IMG_1099.jpg
More to come as it develops. I also have come up with a new theme and paint idea for this truck that i think will be awesome! Thanks for looking.
Scott

Re: Aeromax Rotating Wrecker
 

Thats an impressive build , i cant wait to see the finished product .

Re: Aeromax Rotating Wrecker
 

Thanks bigpipes!
As it would happen. My order of aluminum tube was "delivered" yesterday. Much to my surprise it wasnt here. Not sure where ups dropped the ball but im still tubeless. Called online metal store and mcmaster carr, online metal is sending another piece and mcmaster is calling ups to find out whats going on. A delay that im not happy about but hopefully i'll have some updates soon! Thanks for the patience
Scott

Re: Aeromax Rotating Wrecker
 

Thank you for showing the bearing, as I have trying to tell what I'm using as my base for my platform for my Liebherr LTM 1030.

Good job keep it up.

Texken

Re: Aeromax Rotating Wrecker
 

Very nice work. I like the attention to detail with the side skirts. Gonna be a nice truck i can see

Re: Aeromax Rotating Wrecker
 

Just watch your credit card with mc master! I had parts missing, and the sobs billed me for the replacement parts. I haven't bought from them since.
Later Neil.

Re: Aeromax Rotating Wrecker
 

The aluminum has arrived! Finally haha. Now i can start on some more work soon.

Thanks Texken!

Thanks Valiant! I see that u live somewhat close to me also haha

doodlebug thanks for the heads up! I got the problem resolved now and have material in hand.

Thanks for the comments. I'll be posting some more stuff soon.
Scott

Re: Aeromax Rotating Wrecker
 

Just a small update. As the aluminum tube has arrived. Probably wont do anything on this until after the new year. My weekends are pretty busy until then.
Aluminum tube

Just a mock up haha
http://i99.photobucket.com/albums/l2...d/IMG_1102.jpg
http://i99.photobucket.com/albums/l2...d/IMG_1103.jpg

Its going to be 3 sections as u can tell. They are 2 feet long but will be cut shorter when i go to build the boom. Thanks for looking!
Scott

Re: Aeromax Rotating Wrecker
 

Nice job! its turning out great

Re: Aeromax Rotating Wrecker
 

Thank you!

Re: Aeromax Rotating Wrecker
 

Did a little cosmetic and functional things today.
First off i started the lift axle hoop. My soldering torch took a crap so i was only able to temp solder it in place but u get the idea
http://i99.photobucket.com/albums/l2...d/IMG_1105.jpg
http://i99.photobucket.com/albums/l2...d/IMG_1106.jpg
Then for cosmetics i put the exhaust on it. Modified stock stacks
http://i99.photobucket.com/albums/l2...d/IMG_1107.jpg
http://i99.photobucket.com/albums/l2...d/IMG_1108.jpg

Thats it for now. Let me know what u think!
Scott

Re: Aeromax Rotating Wrecker
 

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
http://i99.photobucket.com/albums/l2...d/IMG_1109.jpg
http://i99.photobucket.com/albums/l2...d/IMG_1110.jpg
Got this assembly from a friend of mine (thank you) And put it together
http://i99.photobucket.com/albums/l2...d/IMG_1112.jpg
Then i marked drilled the tube and drilled and tapped the delrin
http://i99.photobucket.com/albums/l2...d/IMG_1113.jpg
Then inserted and bolted it together
http://i99.photobucket.com/albums/l2...d/IMG_1111.jpg
http://i99.photobucket.com/albums/l2...d/IMG_1114.jpg
I then cut the second section of boom and just mocked it up to see what im working with
http://i99.photobucket.com/albums/l2...d/IMG_1117.jpg
http://i99.photobucket.com/albums/l2...d/IMG_1118.jpg

Thats all for now. More to come soon. Let me know what u think! Thanks
Scott

Re: Aeromax Rotating Wrecker
 

This is a very cool ride. You are doing a great job, and keep up the good work and pic's coming.
Can't wait to see "the beast" finished.:);):D:cool:

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

Found this website,call these folks tell them what you need they may can help.

Re: Aeromax Rotating Wrecker
 

Thanks pumptech. Ilooked around too on robot mp and found this one which will do just fine for me
http://www.robotmarketplace.com/products/0-B104.html
Gonna order it and try again! Thanks for the info
Scott

Re: Aeromax Rotating Wrecker
 

This is wicked buddy, nice going!!

Re: Aeromax Rotating Wrecker
 

Thanks!

Re: Aeromax Rotating Wrecker
 

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
http://i99.photobucket.com/albums/l2...d/IMG_1119.jpg
http://i99.photobucket.com/albums/l2...d/IMG_1130.jpg
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
http://i99.photobucket.com/albums/l2...d/IMG_1121.jpg
http://i99.photobucket.com/albums/l2...d/IMG_1122.jpg
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.
http://www.youtube.com/watch?v=O9NuE...ature=youtu.be

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.
http://i99.photobucket.com/albums/l2...d/IMG_1127.jpg
http://i99.photobucket.com/albums/l2...d/IMG_1128.jpg
These are with the second stage section in

http://i99.photobucket.com/albums/l2...d/IMG_1129.jpg
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
Scott

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
Scott

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
http://i99.photobucket.com/albums/l2...d/IMG_1136.jpg
Modified delrin
http://i99.photobucket.com/albums/l2...d/IMG_1137.jpg
Installed in the tube
http://i99.photobucket.com/albums/l2...d/IMG_1138.jpg

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!
Scott
