If you want toughened glass and its a flat panel then make a template and take it to a glazier.I had one made for my boat for next to nothing. Toughened glass will always have a kite mark or manufacturers mark and is heat treated(tempered) after cutting and edge grinding. Dont even consider trying to cut it.

Company called Spartan do plant glazing in the NE Kev (No everybody not flowers)!

Worth a look.

Gonna start getting ready for this summer now and first thing I am going to look at is a home brew version of a 3" straight through cherry bomb using stainless wool instead of the traditional glasspack.
there is only 1/4" between the inner core and outer body this is due to the heat shield I have being only just under 4" dia so everything has to be quite compact, you will see what I mean over the next few days

the raw materials:D

Looks interesting!

Just to warn you, I packed my exhuast with wire wool to get through IVA and it disintegrated into dust after a few hours of driving!

It better bluddy hadn't John:mad: as it is the proper stainless stuff from an exhaust company.

Ah, you're should be alright then. Mine definitely wasn't proper exhaust stuff!

So I have started with the outer case and some heat and gentle persuasion with a nammer and it all curls round enough to make a nice tight fit for the 3" perforated inner of the bomb



next was to tig on a 90 degree bend that would eventually be sliced to allow it to go inside the cast exhaust outlet of which I will be refurbing and possibly getting a proper rechrome

Made the slice in the 90 degree bend and offered up the outer casing and fits up good so now to wrap the inner core with the stainless wool, managed to get two full wraps and this left it a nice snug fit when I fitted the outer casing should be tigging it up tonight.

Not far to go now, have tigged up the open end

All fully welded up bar the v band collars which I will be doing today.
