MFH's 908: on to the suspension

A mere 4 hours got the front end assembled.



Lots of little unidentified wee little gubbinses. Interestingly the tie-rods (centre right, next to a pair of A-arms and still attached to a 'sprue') are marked L and R on the sprue.



The machined shock absorbers and wire springs are lovely but a pain to install without something getting fired off into the ether.



Sadly, like most MFH kits, it doesn't steer, and there was no easy way of making it do so.



I am very fond of the slightly transparent yellow plastic, which mimics unpainted fibreglass very nicely.



On to the rear suspension. My overriding fear, of course, is that once the engine is mated to the tub. the car won't sit square on its four wheels. Given the amount of horsing around to assemble the rear end, I decided to do the suspension next, even though the instructions say I should mate engine and tub first and then assemble the rear suspension.



First observation is that the U-joints in the rear axle are not in the same plane but 90 degrees out. Seems to me this is a  recipe for driveshaft vibration. See my sketch.



Next the ducting for the transmission interferes with the exhaust and the upper radius arm locating the left rear wheel. A lot of cutting and filing ensued. Getting the hubs on straight required a lot of cursing. Finally I drilled through for #0-80 screws and nuts to hold it all together. What a proper little go-kart! And bonus! it all seems to sit square.





Next up: a bunch of subframes supporting various overflow tanks;Stay tuned!
