Door hinge weight?
Scraping for places to take some more mass out of my antique. I'm curious what the door hinges weigh. Anybody have a set on the shelf that they could get an accurate weight of?
Thanks for any help.

- You might be able to cut the hinges shorter ..but the penalty will be some strength. Mine are just stamped steel.
- Have you tried thinner glass from a newer C3?
- Thinner-wall exhaust, lightweight muffler?
- Aluminum suspension, carbon fiber brake rotors, AL brake calipers if you can find them (big weight savings in the brakes)?
- Aluminum cross-member?

- Have you tried thinner glass from a newer C3? Yes, I have the thinner side glass from a late C3 that I'm adapting to my early '69 window regulator design.
- Thinner-wall exhaust, lightweight muffler? From the transmission back, my pipes and mufflers are aluminum.
- Aluminum suspension,Yes (C4).carbon fiber brake rotors,Not currently $/# justifiable with my budget, but I do have lightweight Wilwood rotors on aluminum hats. AL brake calipers Yes, Wilwoods. if you can find them (big weight savings in the brakes)?
- Aluminum cross-member? Transmission, differential (C4 batwing), and under-radiator crossmembers are aluminum, and I'm currently fabricating the lower control arms crossmember in aluminum.

A manual aluminum rack, get rid of heavy steering box and all its associated parts to make it work, there's weight reduction in the steering colum and the iron master cylinder and booster heavy. I'm guessing you have already ditched the heavy brake stuff, I d bet weight can come off the rotors and of course aluminum calipers. Of course you have the super light lithium battery, light starter and light flywheel.
featherweight seats put originals in storage for resale someday. Do you have to roll the right window up and down put it in up position with light aluminum and remove the window regulator.

There's a man on speed talk has had the record bonneville for 650cc for a stock frame it's a triumph. His record recently broken. He mentioned if you even have a finger out of place it effects speed. I told him get your *** off the bike and get your 5' tall 100lb girlfriend, wife or daughter teach her how to ride it for better aerodynamics. You can still take credit for building the bike that holds the record. Lol

Looks like they've even scooped out the heads on some of them. And they are on sale!.

Years ago a friend of mine who ran a sprint car team showed me some titanium bolts. Pretty neat pieces, but damn, the cost per pound of weight reduction takes your breath away. They make an aluminum block price look almost reasonable in comparison. I've wanted to replace a lot of the engine bolts with titanium to get additional weight off the front, but until I win the lottery I'm stuck with the present steel bolts.
During slow moments in the garage when I'm stuck with a problem I can't immediately solve, I've drilled "scoops" in some bolts while waiting for a solution to pop into my head. I won't tell you how many bolts I've scooped out, as you might do the math and figure out how often I'm scratching my head, stumped from a problem. I also recall rifle drilling the bolt that attaches the parking brake cable pulley to the crossmember.

Regarding the side windows, I'm going to swap in lighter material where doable, but as this is still a street car I need to be able to roll the windows up on a rainy day.

No I ment on the passenger door only fix it to the up position permanently. The driver side of course you have to be able to use it. 16 lb battery pretty good. Lithum battery is stronger in cranking capacity and can last a lot longer in sitting without a charge. There only downside is they do not crank as well in cold conditions, why I dont know. I know you have a great stereo and speakers at your house to listen to the radio and speaker not needed and a jacket is fine no heater stuff needed. I'm riding my motorcycle all this winter and I sure dont have any enclosed cockpit to fend off the wind chill factor like you do.
The battery in my triumph weighs 9 1/2 lbs will be replacing it with lithium that weighs 2 lbs with more cranking amps. A motorcycle like mine is only 74 cu. So any weight on it is true death to performance. The cat converter is 5.5 lbs its coming off and both mufflers combined 14 lbs. Center stand gone 2 lbs. Now if I could do something with rider weight be a big help. Lol

$17.97 at wally 50 lb accuteck, postal 86 lb for $24.99. Going for the gold colored 86l b. Same color as a past vette.
let's see the average hourly wage in the USA now almost $26.00 an hour. I have no doubt the scale is USA made. Lol.
