So…
The Minx is going to use a layshaft, which is a first for me. I looked at various designs and bought an off-the-shelf layshaft from eBay. The quality however, was terrible, so I’ve ended up having one made. £32 cash...thank you very much. I have all the sprockets, one of which will have to be made to fit the shaft, as it's too small.
I have fabricated some brackets to make the layshaft adjustable to keep the chain tension right. I may have to offset the engine to the right by about 100mm or so to get this to fit where I need it. Is having the engine off-centre a terrible idea? Please let me know.
I’m still waiting for the keyway to be cut, so all this will have to wait for now.
It was a relief to get the wheels on for the first time. The proportions are all on paper and theoretical until you see it for the first time with the wheels on. Ride height looks good at just under 100mm.
I have started on the body framework using thin-wall 19mm round and square tubing. I opted for round as it’s easy to bend in my tube bender, and I can also notch the ends with my notcher for butting the joints (all the gear and no idea). Sorting the steering wheel position was a bit tricky, as the seat and pedals are adjustable, but I’ve managed to get it so it’s not such a compromise in either position.
The steering wheel will be a 12” laser-cut number from 4mm aluminium, very similar to the ERA. I find the smaller wheels more reactive and take up less room in the cockpit.
I’m hoping to get all the parts for the layshaft so I can start fitting this weekend.
Let me know what you think of the off-set engine?
