After disassembling vent windows (to get re-chromed) I noticed one glass was marked with a large "SEKURIT" (nothing else) and the other (passenger side) is marked with a smaller "DURO-GLAS" with a "squiggly line D-01/A S2" below. Is this a replacement or just another part of the infamous zwitter parts mix & match?

Also I am going to attempt to build a fixture similar to the one shown in the factory manual. I am sure others have made one any advice or dimensions would be greatly appreciated.

I know Duro also supplied glass to VW. While it is possible that the car came off the line with mismatched glass, I would expect that to be highly unlikely.

What fixture are you referring to? I built one for my shop mate to press the glass back into the frames on my '57, some pics are at thebugshop.org. It's pretty easy.

I have always been able to just pull the glass from the frame with my bare hands. I think once I soaked one in hot water first. You can pull the ends away a bit at the start. Before re-using (or rechroming) bend it back if it got distorted any.

You can make a with some plywood and a couple pipe clamps. Idea is to not let the frame distort/open up at all. Pretty easy to do. I would link/post the pics from thebugshop, but I have that site set up so images can't be direct linked to keep the bandwidth from going up....

coming apart was fairly easy but I am concerned about pushing glass into new seals. I Googled "VW 737" and found this link on how to make obsolete VW tools and there are detailed drawings to make one...go figure.

what happened to the old days of the rubber mallet...guess I'm old school.

Yea...but I like tools. You can never have enough tools. Special tools, odd tools, shiny tools. There's a tool for every job, a place for everything and everything in it's place. :D

I have a Northern Tool poster on the wall in my shop that shows a workbench and the text

"There is nothing wrong with not owning any tools. Just like there is nothing wrong with holding your wife's purse for a minute."

When I did mine, I used a Black and decker workmate and plywood forms. It is kind of scary when you start putting all that pressure on the glass but it worked quite well.

Yep, me too.

That's inventive John, must have been quite an event, I guess nothing ventured nothing gained. I will be doing mine eventually :shock:

Make a special tool for a job I do once evey 10 - 15 years? Not if there is another way.....

Use a couple Bessy clamps with the orange plastic ends. Use one to keep the keep the frame from spreading, the other to push the glass into the frame. It's going to be diagonal, so put a block of wood between the clamp and the glass. To keep the glass end of the squeezing clamp from slipping use a third clamp between it and the top of the frame. Glass is hard to break under compression -- just don't put a point load on it. Make sure you lubricate it well (I use 409), and don't let it dry before you are done.

The same technique works on split and oval vert side glass.

Dude, you're sick. That is way over the top. Very nicely done, so what if you never use it again. Nice job...!

Sun Apr 04, 2010 6:09 pm

Thanks John. Yea who knows how much it will get used, I have 4 vents I will be doing but I do belong to a local club and maybe someone will use it. I have spent more time and money in a bar and had nothing to show for it the next day but a headache :lol:

Does it work as good as it looks?

The clamps on top are a good idea. Mine was far more primitive but took 10 minutes to make. That thing is beautiful maybe you can sell it to a restoration shop.

It worked great pulling the glass out. I have wrestled with a couple before, slightly spreading the frames and wiggling them back n' forth but this jig pulled the glass out effortlessly. The frames are out getting re chromed. I purchased new rubber from WWest, pushing the rubber back in is going to be the true test.

Anyone have an easy way to trim the rubber behind the gutter?
