I have a "Fyrak" spotlight that I would like to install through the windshield of my '26 coupe. I have seen glass hole cutting bits made by either Fyrak or Clymer for cutting this hole. I'm sure anyone lucky enough to have one of these rare bits would not considering loaning it out to me (and rightfully so), so in the absence of one of these glass hole cutters, what is the best way to cut a hole approximately 1 1/4"? Thank you. Jim Patrick
Take it to an automotive glass shop for install
Safety plate has that plastic film layer sandwiched inside, doing home made cutting would be tough, glass shops have the tools and skill.
It's not just the bit you'll need. The diamond bits this large MUST be used with a drill press that you can adjust the speed down to about 600rpm. You'll need a way to hold the glass and you'll need coolant. The bits aren't that expensive but all the necessary equipment and supplies add up.
Here's a bit:
Here's the coolant:
Here's a coolant pooling ring:
You can also use a ring of modeling clay to pool the coolant around the bit. Don't be stingy with the coolant and don't use plain water. There's a lubricant in the coolant too.
Thank you Ken. Good advice. Jim
You can sandblast a hole thru the windshield. Clamp a rubber doughnut to one side and blast your hole thru the center of the doughnut. A fellow in our club has done several.
Hey I have a question about this post...
The guy I bought my 24 roadster from had a 25 coupe in the garage (all restored). He had what looked like a bullet hole in his windshield - kind of bizarre looking. He told me that he had no idea what it was for (and he's had the car for 15 years) and never seen another one like it. Is this what was in his front windshield?
Here's a photo of a windshield mounted spotlight:
Here's another shot from behind:
Paul, if it was nice clean round hole, approximately 1 1/4" dia., it probably had one of these lights mounted through it at one time. Jim Patrick
That is exactly his car!! It's a 25 coupe and the mount for that light is exactly what it shows in the picture. Cool!!
This one was cut using the bead blast cabinet. A piece of rubber with a hole in it was used to define the hole.
