im so excited!
my first bruder. ive been wanting a rc excavator for years,after seeing the price on the nice hydraulic options....i quickly backed out. so i finally pulled the trigger on a poor mans option. plans -screw drive simulated hydraulics -servo drives -electrical slip ring -lights -possibly metal bucket and boom -added counter weight. im blown away by the detail of this model,no wonder bruder is the top choice for these conversions. more pics to come. at the moment im still stocking up on parts before the build.                   test vid of 360 rotation with the slip ring installed....no tangled wires here!  slip ring test with power applied,tested all 6 poles,light never lost brightness. full 360 rotation,no wire tangles.

it gets better!
got a few supplies today! 1/4 inch masonary bits to serve as the screw! made the rod and barrel for the bucket cylinder tonight aswell. when im done the cylinder will stroke,and the rotating screw inside will be hidden. others build the similuated ram differently. the barrel of the cylinder turns. mine wont....hopefully. the bad news,ive injured myself,and the capasitor on my lathe went out. so no more parts making for me!

the rotation switch went out on my lathe,due to the hot/ground contact.
so ive managed to figure out how to hotwire the lathe to run in right hand rotation only. the first cylinder was just a mockup to test the concept,now im building the actual cylinder. bigger is better!  its late,ill call it a night! the old barrel fits inside the new barrel. tomorrow ill make a new rod. this barrel has a shoulder on the top which serves as a stop for the rod. when the rod reaches full stroke it will bottom out in the barrel. this will ensure my bit doesnt fully unscrew from the rod. boring the barrel pics!

heres what i think will be the final design.
ive added a larger piston to the rear of the rod,this will serve as a beffy place to insert the set screws,also keep the ram straight,so i wont have the cylinder when extended look bent and sloppy. the tolerences are tight,with no seals installed,if i put my finger over the rear hole and pull the ram out....makes a nice vacume! i was even thinking about installing orings,but i go that route ill need to vent the ram.

Looks pretty cool, I'm following along
Are the main parts of the body plastic or metal?
