door glass sash clamp?!

Post by 230ew123 » Fri 01 Dec, 2017 2:57 pm

Was wondering if anyone knows of a replacement part for the glass sash clamp used to attach the glass to the regulator within the doors?

I have taken apart 6 doors from wrecks by now and have observed that all get rusty between the rubber and the pressed clamp..epc only has a part which includes the glass, which is unnecessary as the glass is often in excellent condition.
Has anyone had a go at making a new one or found some sort of replacement universal auto glass clamp?

Perhaps someone with a 3D printer can make something for the job, or print it directly onto the glass?

not sure if folks could print a steel clamp, but, I am open to it...

can't believe that it does not seem to be an individual part rather than getting the whole piece of glass too. It would be a piece of steel to rust for sure within the little hot house within a door, even if the door was well drained, the humidity would get the clamp.

Been soaking the clamp in molasses (yes it does dissolve rust whilst leaving the paint, cheap), sand blasting and a bit of grinding, but there is not much steel left..

It seems that there is not many after market auto glass clamps around, some for gm..

two common gaps I see in the w123 spares market are the door glass clamp and the spring tab to hold the bonnet up on the lh front, very easy to snap if thoughtlessly closing the hood. (sort of thing you would only do once and, doh, I did it) It would be great if one could just get the sprung tab with a boston style bolt without having to get the whole hinge..

There are plastics which are as strong as steel. I don't know if they can be printed though.

yes such as epoxy resin and kevlar and or carbon fibre, but the steel clamp works by tension created by the spring compression of the steel wedged with rubber. The rust grows between the rubber and the cupped steel.
If it was made from plastic it would have to incorporate some threaded grub screws to achieve tension along with some really good glue to hold onto the glass..

hmm, may have to look for a steel channel u section and weld the mount bolts on..

either way, a project

(g'day Tony!, how's your musso going?((I ended up getting a hj75 troopy to run on veg eventually, I reckon twin cabs are not the best design..)

:)

I see what you did there ;)

It's possible.

I haven't got any fancy plastics at my disposal at the moment.

What i did to fix mine was to wire-wheel out all the rust and weld in new metal. wasn't the prettiest, but it worked really well.

I think i will give this a go :)

I'd have to do it in a couple different sections due to my printers size, but I'll plastic-weld them together afterwards.

It'll be in PLA plastic as a first prototype. but if successful I'll offer it to others and use a more appliccable plastic material. maybe some Carbon Fibre embedded plastic.
