ANOTHER AUSTIN 7 TWIN CAM
« on: 19 Apr 22, 06:27 pm »
Hi all,

I thought it was about time I properly introduced myself and started my build blog.

My name is Ian, but most people from the RAF or motor racing know me as Billy (long story).  I'm in my mid 60s and was in the RAF as an aircraft technician for 35 years, then a project manager and engineer restoring warbirds (Hurricane and 2 Spitfires, and now work as a logistics and maintenance engineer.

In my spare time I like anything vehicle orientated and have built a couple of kit cars and designed and built my own racing cars.  I was the Competition Secretary for the RAF Motor Sports Association for many years and managed a Sprint track, a Speed championship and a Racing championship.  I think you guys have a fantastic thing going on here and I would gladly assist wherever possible (I have various safety cases, regulations, forms etc that can be easily adapted to your use and would be willing to share these with you).

Anyhow enough blabbing on about myself, so I have attached a PDF of where I am with my Cyclekart.
 
Also many thanks for all the info people have posted on the forum and the many informed answers I have received to my queries  8) ;D

I love the background story.
We must avoid torturing our brains with false problems, it occupies but it can annoy. In jest!

Definitely following this one with interest! Look forward to getting onto the track with two or 3 of these, to see the various solutions to arriving at a similar end point.

In the meantime I will be poring over your drawing notes to compare sizes! Keep us up to date with the build.

great stuff! What size steel did you use for your main tubular structure, Ian?
I don't want to bore you all with the details, here. But if you are interested, have a look at my blog https://peteskart.blogspot.com/

I like your bending jig for 1/2" square tube (I like all the build - way ahead of me already). Keep posting please.
I'm not quite as green as I'm cabbage sounding.

Thanks for all your comments  ;D

The chassis is being built up from leftover lengths of tube from my race cars rather than specific requirements for a Cyclekart.  The chassis is multi-tubular and not a spaceframe, lozenging will be prevented by a stressed alloy skin rivetted to the frame.  Main tubes are 3/4" box 18swg. the vertical tube by my hips is 2"x1" 16swg tube (trailing arms for axle attach to these).  Cross tube at rear that the engine frame ties onto and that also braces the rear of the trailing arms is 1.5" x 1" 16swg box.  The curved hoops are 1/2" 18swg tube.
