I think attitudes to safety have changed to, or maybe just with some people. I have a friend who at over 50 who started classic racing and he has every safety option possible, so much so that I could not race his car because of clostrophobia (spelling?) and the fact that so little of my body can actually move ... yes I have driven his car around the pits and to his trailer, awkwardly.Ah! Roll bars! In the early days of SCCA, a roll bar was more cute than functional. Today, the simplest "broom handle" test is hard enough - without a full Duetto windshield, the top of his roll bar has to be pretty high, as the front end of the broom handle rests on the car's hood. They sure are ugly compared to the svelt things we drove in the 60's. I always thought it was so hard to flip a Duetto that you really didn't need one at all......
But I raced bicycles without any helmet back then too.
Quite an offer thank you, and one I hope to take you up on one day!Thanks for the kind words, Bill. If I ever have a chance to race at Circuit of the Americas, I'll give you a heads up. OTOH, if you're ever in the PNW during a race weekend, shoot me a note and I'll put you on my crew list to get in to the races for free.
Yeah, double guns above is a bit much. Single gun would have sufficed. I couldn't help it, I was relieved of anxiety, overjoyed with results, and my Alfa cup runneth over. At least I had sense enough not to wink with the guns.
You should cut the whole mess out and have a knowledgable race fabricator build a lighter functional roll cage.40 lbs? Are you drunk? If I sectioned out 4" of tube from each side of the main hoop, what would that weigh?
Yeah, what's up with that? I'll look into that later. At least it's alyoominium. Speaking of which, here's my stock of metals. That's a Stanley Vidmar cabinet, so each drawer can support about a teaspoon full of dwarf star. Near part of the drawer is all Ti, and far part is the plastics. Steel and Al loosely organized in the middle partitions....That spica blanking plate looks chunky
18 teeth. No crank-fired ignition allowed. Besides, my Marelli is Plexing with great fortitude!...How many teeth on the original SPICA pulley out of interest?
Oh, you mean like this bolt treatment on my KTM SMR? The whole bike is like that. The clutch basket is so drilled out, it looks like a spider's web. In the lower left, you'll see the titanium clutch bleeder screw that I made (has a rubber cap).ps: serious weight saving is often done by counter boring the ends of all bolts as that part does nothing, or drilling holes through large bolts ... lots of machining for you .
