Looks to me more like something you'll wave around to discourage people from overtaking you!

That's going to look good on the car, another bit of bling, every bit helps.

Whatever it takes!   I'm thinking of adding the full James Bond counter-measure armoury.

Re: Bugatti Type 37 Build - handbrake
« Reply #152 on: 02 March 2021, 07:22:41 pm »
Had a chance to progress the handbrake today.   A rod from the handbrake lever runs back along the outside of the bodywork (just because I like the look).  It then operates a lever which then pulls a Bowden cable that will operate the brake pedal (Graham Appleyard style).

Finally got my gloriously complicated version of an Appleyard handbrake installed.  Had fun making it.

Re: Bugatti Type 37 Build - belt change
« Reply #155 on: 11 September 2021, 03:14:40 pm »
I’ve not changed the belt on the Comet since installing it.  3 years on, it’s 3mm narrower and has lost a tooth.   Time for a new one.

It does look good. When I'm not rushing between jobs to get to our events with a cyclekart this time, I will do a similar thing. I like the idea of the cable pulling the brake pedal.
The full Bond defence mechanism don't forget, includes a three foot wide by two foot high 1/4" thick solid steel, bullet proof screen!
Very important that.
Can you talk GA into one as well?

Re: Bugatti Type 37 Build - bent TC
« Reply #157 on: 13 September 2021, 03:40:14 pm »
Hmm.  I seem to have bent my Comet Torque converter.   Chain is not too tight at rest.  I removed some but not all fins to allow clearance for the chain.  Any ideas?  Possibly engine movement when vibrating (at resonant frequencies this could be quite noticeable so I added support to the engine mount)?

Hmmmmm was it always like that and you just hadn't noticed maybe?
Possibly heat generated when you removed some of the fins distorting the metal?

Yup end of my ideas?

Do the belts get tight on those cvt drives? If they do it could be the stretch of the belt pulling it over and removing the strengthening possibly may have an influence. They are only about 6mm ally if I remember rightly. You could put a brace on the back where the lug is on the top to the chassis. I have something on my drive train to reinforce it.

Actually looking at it again, it could be the pull by the chain when you accelerate and brake.

Strip it down and lay the casting on a flat surface then you should be able to see if it's twisted or bent.

It does look good I must say.
If my engine will do 10,000 rpm, can I just change the scale so max is 10,000?

Whoops sorry, the above post is in the wrong place, should be on Stefans Tacho page. (Saying that's made me hungry).

Re: Bugatti Type 37 Build - Freewheel hub v2
« Reply #164 on: 23 September 2021, 08:52:36 pm »
Version 2 of my freewheel seems to be working OK so here's a drawing of the set-up.  To lock the wheel I just add a key into the Gemini Karts Hub and then tighten the hub onto the axle.   The oilite bush set into the end of the hub gives lateral bearing and also supports the wheel better.
