so Iam putting my car back together and pick up the big metal window winding mechanism and weigh it and its 1.25kilo!

so, its a long shot, but I was wondering if anybody else has tried to fit a different winder meachanism or fabricated their own with success?

some hyundai Excel ones look light and simple from a photo but i havent held or weighd one and havent even sussed how it could be fitted.

just trying to save a few kilos where possible. it all adds up.

something like this might not weigh much and could be made to fit?

Will it really be worth it?

Lexan windows with little sliders so you can get some air in haha

Can you just drill a stack of holes in the mechanism to drop weight without going to the trouble of fitting something else?

I did start drilling holes in the original but one hole wheighed 3-4 grams (12mm) and so i didnt want to drill 100 holes for 3-4 hundred grams in each unit.

I think its worth doing. if i can save 1 kilo per door thats 4 kilo. all these little things add up as I am a bit of a weight NAZI. as long as it doesnt cost heaps of time and money.

I think my mazda has the cable ones in the door so i might take that out tonight and weigh its worth...

well i might leave it for a rainy day now that i have weighed an alternative.

the mazda one which is as simple and probably as light as possible is 725g so that is a weight saving of 525g per door. I hoped for 1kg (bit optimistic I guess) there is a Kilo of metal on the bottom of the glass though which could be made from alloy and reduced amount of alloy at that, that would probably save 500g so one could get over a kilo per window winder system.

it does look like it would fit quite easily at least, with a small amount of fabrication. but not as lghtas i hoped so rainy day project if it ever rains.

as you were...

It's certainly worth it. It's a weight saving from a reasonably high part of the car which should help with the moment of inertia acting about the COG.
Lower the COG and the moment decreases.

well it was raining today so thought more about this.

one thing that was holding me back was how to replace the 1 kilo of metal on the bottom of the glass as I didnt really know how it was fixed in place.

but it appears that it is just a clamp type setup.

with a small bit of 'over bent' 1.6mm alloy and some rubber squished between that and the glass then this little piece in the pic, is enough to hold up the 4kg of glass and original metal bit! very strong. definitely enough to stay attached when winding the window up and down.
so now it seems i can replace the bottom steel with a couple of bit of alloy. one small triangular bit for the guide at the front of the windows and one snall bit for the middle of the window base to bolt on to the mazda winder.

that should be easily made with 200grams of alloy so a saving of 800grams!

combine that with 500grams from the winder and if i make the side guide bits from plastic or alloy i could save another 200-300grams.

so all up per door about 1.5kilo! awesome indeed! 6 kilo!

Sweeeet as.
More photos required so we can copy your handy work.
I'm always keen on minimising weight.
