I don't know who Keith is and have never seen this spreadsheet BUT - multiplying by 2 for a sliding caliper IS correct as the aim is obviously to make the...
Thanks Rick, the goal was actually to determine the braking torque from the pads, given the hydraulic line pressure, not the other way around. Keith Tanner...
I got really tired of the sketchy writeups of things like spring rate calculations and brake calculations so I derived them myself. Take a look. If yo find...
Hello everyone, I am a new member to this wonderful club. I am a mechanical engineering student (3rd yr) with good practical experience about cars. I am also...
I don't know about Canada but in the UK the insurers usually base their prices on the nearest equivalent kit car. If you are building a seven style car they...
Les, I believe that what you are saying would apply to Canada. I have yet to find out however about the car I am building curently. I heard here (Ontario) from...
Hi Stan, The discussion of the rusting Lotus frames has moved to other Forums. I spoke to this issue on the Locost of America forum. See you there. Philippe.- ...
Hi there, I would like to introduce myself, my name is Ciaran. I live in Adelaide S.Australia, curently studying an advanced dip. Mech. Eng. I have been...
Hi there, Ciaran Here again.... Well, on to the next question. My every day get around car is a maza Eunos mx3. I was changing the clutch on the weekend and...

Before I make myself a (yet another) frame that doesn't pass the traditional rigidity test (less than 1 degree of strain per x foot pounds of stress, where x =...
Jack, The welds do almost nothing to change the stiffness. The total deflection is an accumulation of the deflections in each of the components in the overall...
... Doh! You're right of course. I probably shouldn't have mentioned stiffness at all (re the round H tubes)...though square tubes are slightly stiffer in ...
... Makes sense to me. My missus had an Elan, and the above pretty well describes its chassis. If the entire tube structure of the driveshaft tunnel were...
I could have asked all these questions in one message, but this way seems less confusing than the double-aught shotgun approach. ... Yeah, it's a huge unboxed...
My incomplete build currently has a tube tunnel, to which I was going to weld sheets. However, I keep looking at it thinking I could eliminate the tubes if I...
Perhaps not.. Somewhere in the Archives/files there was(is?) an Engineering Thesis on Structural/torsional rigidity in a Locost Chassis.. It was carefully done...
Mine has a sheet tranny tunnel. Uses 19mm tubes at floor level only. The bottom is open, and I intend to use a bolt on 2mm Ali cover to make it a complete...
... I found <kitcaranalysis.doc> in there, which suggests a sheet driveshaft tunnel, and some mods to the front end bracing, will more than double the...
Jack: I infer from your post that you have made and tested at least one previous chassis. If so, what was the stiffness? I would like to know because there ...
Bill, I think that for a honeycomb structure to work as it should, all of it has to be attached to the cover sheets. Can you spare to lose 2" of foot well...
