Hello again :hi:

 

Some of the older members may remember me and my 2b

Sold it nearly four years ago now and since getting married I've been allowed to start my new build.

 

This time I'm going with a scratch built and doing a Haynes Roadster.

After studying the book for a few weeks and familiarising myself with the chassis plans, reading up on the various forums; locost builders, roadster builders and haynes forum. I took the plunge and ordered the steel for the chassis.

 

6 lengths of 25x25x1.5mm ERW

3 lengths of 19x19x1.5mm ERW

and three 19x1.5mm ERW tube

 

Built a build table using 18mm phenolic resin ply (was free)

Been busy on the chassis this last week although to the untrained eye it won't look like much.

 

Made my suspension brackets. Sixteen of these needed making

Meanwhile, the front hubs had been soaking in Bilt Hammer Deox C and were completely de-rusted.

 

They were rinsed, de-greased, primed and painted

The next day, jigs were made for aligning the front suspension mounts

Rears done next, no need for jigs just careful, accurate measurements

Today I made the steering column support

Chassis now fully welded up, alternating sides as fast as possible to stop any heat distortion from the cooling welds. Managed 2mm distortion over the whole frame which is good enough for me seeing as most production cars are lucky to see 4mm!

Chassis looks lost at the back of the garage!

looks awesome so far. Are you going completely by the book? i've come across a few bits in the past about adding a few extra tubes here and there to increase the stiffness. Pretty sure i've seen it put through a computer modelling program to evaluate the stiffness. Sorry don't have any links but could be worth a google search if you haven't already.

 

Good job, looking forward to seeing the progress.

 

 

here is some stuff about chassis stiffness - http://locost7.info/mirror/aussiemods.php
