It's now getting techincal....

Well what can I say the front uprights have arrived and I am impressed. The bottom hole was to accommodate a Transit MK1 top ball joint but opted to drill the hole to take a 5/8 UNF studded rose joint as the top.

As I am not following a definitive set of drawings just a picture off the web I can't cut and shut a set of wishbones. Taking my experience from my Locost build and doing a bit of digging it came apparent the ratio between wheelbase and track  is 1.618 to 1. So the first job was to widen the table and try and work where the front wheels would be and use the above calculation.

 When I measured and re-measured, taking the steering into account it came apparent the chassis is a around 100mm short, its no problem as the back end is still to be finally welded.

The track will be 1340mm and wheelbase 2160mm

 It looks daft but once I get the geometry correct I can construct a set of front wishbones. Again I will use the same method as the Ron Champion book.

Got a bit bores today so decided to weld in the 5/8 inserts to take the studded rose joints, gave the MIG a good service as my welding was still not up to scratch. Purchased the relevant bits to go with the uprights form McGill Motorsport even cheaper than Ebay.

 

 

 

Took the tube and drilled 4 holes and left 2mm of the threaded bar protruding for a good weld.

 

 

The welding is getting there now, a bit of user and equipment issues I think.

 Still undecided on how to attach the wishbones to the chassis, either polyurethane bushes or rose joints.....
