Re: Bruder Liebherr loader build
 

Well,I had a little setback on the boom, wasn't going to reach max hieght, the way I was going with it,with the servo incased in the front portion,had to come up with plan B ,reverse it ,put the servo in the boom,have the new boom tacked together,got the rams made,seems to work much better now ,has good lifting power with just the one ram,will be using two though,now onto getting the bucket going.:D
Have a few pics and vid.

Re: Bruder Liebherr loader build
 

Well , getting a little futher with the loader,got the rear axle mounted up,thought about using one servo with a linkage,thought about it some more,decided to try screwdrives,works well,took apart one of the servo's,desoldered wires on the motor,changed postions of wires,soldered back,to get the push/pull for the screwdrives.
I know my metal work looks pretty bad right now,just getting it all mocked up/tacked together,once I have it mocked up,going to take it all back apart and finish welding everything up,grinding down all smooth.
Have a few more pics and vid.
Thanks for looking

Re: Bruder Liebherr loader build
 

Well, need to order 3 more servo's for the rams for the boom/bucket.Been working on the rear plastic section ,getting the battery in,it fit like a glove.
Cut out some the unneeded plastic to make room for the electronics.
Going to cut off the long bolt from the wheel and replace the hex nuts with some cap nuts.

Re: Bruder Liebherr loader build
 

Looks good! We can't wait to see it rippin around! What rpm and torque are your gear motors?

Reg

Re: Bruder Liebherr loader build
 

Hey Reg ,thank you very much ,should have it running soon.I have to say I'm very pleased with the strenght of the screwdrive rams,quite powerfull.
Ran the boom/bucket up and down /bucket today ,works great.
I am using these motors from robotmarket place,with the battery I'm using ,motors should be around 250 oz of torque.Around 150 RPM

Re: Bruder Liebherr loader build
 

Heavy duty Bruderism, great!
Is the screw drive an adapted hand-drill? One of those that you push with your hand - sometimes called Archimedean Drill? I think they might be much smoother than drill bits, as they are actually designed to be used for a drive (and not cutting).

Re: Bruder Liebherr loader build
 

Hey Jensr Thanks
Just using a regular style masonary bit 1/4" ,been using this style for awhile have good luck with them.The Archimedean Drill would probaly work better,but mabey hard to find in my area,lol .Can't beat the price of the one's i'm using now ,around 3 to 5 bucks a bit.:D
Is this what your were referring

I would like to give a big thanks to whomever voted to make this a 5 star thread.
Thank you very much!!:)

Thanks everyone for all the postive comments:D


Finally got the loader together,the build went okay ,I guess ,had a few set backs on it.First tried to build the boom just like the factory boom,but wasn't going to get full hieght ,had to resort to plan b ,reverse it and put the servos in the boom.
Few more pics of the finshed model.
Will try and get a vid up real soon.

Pumptech-looks like the loader turned out really nice! Good job. Tough digging in that drive-way huh!:D

Re: Bruder Liebherr loader build
 

Hey thanks modelman :) , yea,the wet packed sand was a little tough,should work well with loose dirt and potting soil,mostly what I use at home.
