I have repeated this mistake before and probably will again but I've started acquiring parts for the next project before finishing the current one. I now have enough Mobike rear hubs to proceed with the aquisition of everything-else I shall need such as fibreglass bow limbs for the leaf springs. Two of these hubs will be reworked to run backwards for the left hand side hubs. I also now have one and a half hubs as spares. I have 4 Mobike single side mounted alloy wheels and solid tyres. I do plan to get the Church Pod running before getting too deeply stuck into this project so progress here will largely await progress on the other.
The outline is for a fairly short (40") wheelbase quad with numerous bow limbs used as leaf springs with a steerable hub at every ccorner. Steering will be from a pair of tank style bars. I have a spare TSDZ2 so that will find a home here too. There'll be a three chain system (one to the cassette, one from there to the front axle and a third one from there to the rear axle). The hubs will act as a locking differential across each axle and Toyota Prius intermediate steering shafts will act as driveshafts because they are just short enough, will expand and contract to cover suspension movement and were about the cheapest solution I could find. Like Danny I will probably have to pin these to secure them fully but they can at least chip in splines on the driveshaft part to bite into mild steel on the hub and centre parts as a contributory drive medium. The chassis will be a single beam with a clamping system at each end for three or 4 bow limbs top and bottom. One thing I'll have to experiment with is how much length to allow for the bow limbs to have in order to suspend my lard successfully. Another will be how much to ask the rear to steer in relation to the front and I suspect this will involve some field testing and a field test dummy (me) sucking it and seeing what happens at various amounts and speeds. I'll keep the solid tyres at least to start with as it'll be a pleasure not to have to pump them up whilst building the thing. I'm hoping the suspension will temper the hard nature of them. If they prove awful then I can always get some tubular tyres once up and running which will be a first for me.
