Hi Grant, The suspension arms are made of 3 pieces, 2 lengths of 1/2" round bar, and 1 piece of 3/4" square tube
I just drill a 1/2" hole through each end of the square tube and then weld the 1/2" axels in. Makes for a very robust arm. Then I drill and tap a hole through one of the axels for a 1/4" "eye bolt" and simply screw the eye bolt straight through. Makes sence in my head I'll get a better pic if you want? The attachement chain was far to heavy, and not wanting to sacrifice run time (ie batteries) I chose to rebuild the tracks lighter (TTS) By doing this I saved about 10kgs in chain and sprockets. The batteries weigh 4.2KG each or, 36lbs total. Chris. b On Sep 20, 2:44 pm, Derek Engelhaupt <[email protected]> wrote: > Grant, > > I think Chris wants to shed some weight due to the batteries.
