Cutting glass-Tech O' Matic? RYAN?

I was at Harbor Fright today and saw some Dremel size diamond discs (5) with arbor for $10.
Has anyone used these particular cutters?

 

No.I tried the regular cut offs though.I think my fingernail would be more effective! I'd like to try them.

 

Also, when grinding a curved piece, like a W/S on a gl*** grinder, it's easier with two people who work well together, so one person can support the weight on the end not being ground. Those ****ers can get pretty heavy after a while.

 

Bringing this back from the dead for "tech only week".

 

Is it true that any and all chips should be sanded smooth on all edges of a cut gl*** to prevent future cracks?

 

there was a thread ,I think by Customolds,on cutting windshields with a wet saw.
Might be in the TechOmatic.

 

Choprods, its true the smoother the edge, less likely to break. Thats why the rods are polished in big HP engines, same theory.............OLDBEET

 

the flat glas in my 33 looks like its getting bubbles along the edges, what will stop this?

 

Nothing, moisture will continue to get in......OLDBEET

 

I'm totally ignorant on the subject but curious.
What are the differences in gl***? Is gettig gl*** cut for a flat application no problem at all? Is it just curved that is difficult? What is tempered gl*** whats it used for (windshields? side windows?) and is it a more recent thing?
Lots of questions but I'm sure there are many of us who could use a quick lesson.

 

Nimrod-I think most all cars from65 and newer have had tempered side and rear gl***es. its a safety"improvement"-I suppose...these can not be cut.
a curved gl***[duoplate-two layers] can be cut but sometimes a lil tricky.
a flat door gl*** can be either tempered or laminated duoplate -it depends.....usually a mark in one coner designates the type and sometimes even the brand and DATE..........WHEN IS THIS POST WORTHY OF TECH-O-MATIC?

 

As a sidenote, curved vent windows and small quarter windows can be cut from a Windshield.........OLDBEET

 

Also for 49-52 chopped Chevs. Later Ford PU w/s gl*** has about the same curve, by laying your stock gl*** on top and moving it around to find the rite contour, a chopped w/s can be cut(2 piece). I've done it (in Austrilia where that gl*** is rare) and those w/s here are rather cheap......OLDBEET

 

Nimrod, there are three main types of gl***.1-plate gl*** -single pane or one thickness-used in house windows,ect.When this breaks,it usally breaks in large jagged,sharpe pieces,very dangerous.2-safety sheet-this is two thin layers of gl***,with a sheet of plastic sandwiched between them,when this breaks,it usally just cracks,and the gl*** is held together with the thin sheet of plastic,thus keeping the gl*** from cutting you near as bad,thus the name safety sheet.This type of gl*** is used for side gl*** in older cars and all windshields,even the very newest cars.Reason?-plain and simple, this is designed, to help keep you from flying through the windshield in a bad wreck,you will get cut,but it may save your life.If it breaks,the sheet will hold it together,and hopefully, hold you in the car without hurting you too bad.3-Tempered gl***-this is gl*** that has had a heat treat enduced process,which makes the gl*** very brittle,harder to break,but when it does,it shattters into thousands of tiny pieces.This gl*** is used in newer cars,60s up,used in side gl***es and back gl***es,for safety reasons.You can not cut this type of gl***,if you try,it will just make a loud pop and break into many pieces.
Hope this answers some of your questions.

 

<font color="red"> Damn BEETLE ...once again you prove why when anybody has a gl*** question I point them to you..you always have all the tricks!

We have a bandsaw that uses a diamond blade and a water pump. The cuts are EXCELLENT, fast, easy, no breakage.

Can you please give us some more info on this technique

 

All the tech to the top...
