How to make a glass stencil!

If you have to ask why you are missing the point... simply because we can. (THANKS TECHSHOP DETROIT!!!) This instructable is brought to you by Detroit Glass House, where we love a challenge and are not afraid of process! In the event a glass stencil is not on your "to do" list, please use this instructable as a how to guide for cutting glass on a water jet without a vacuum assist.

*A vacuum assist will allow you to pierce entry points into your glass on the water jet before you cut. If you do not have entry points the force of the water jet (at 60,000 psi) will crack, explode and destroy your glass! A vacuum assist does this by drawing the abrasive material across the water stream before the venturi pulls the abrasive into the stream, eliminating the brief moment when the force is water only. Since TechShop Detroit is brand spanking new their vacuum assist is not set up yet, so we drilled our own entry holes!

Step by Step Breakdown

1. Blow Glass! Create a rondel (or use sheet glass)
2. Create a vector drawing of your stencil
3. Place pre-drilled holes in your file for Water Jet entry points
4. Create a laser template to locate pre-drilled holes on your glass
5. Cut out your laser template
6. Drill holes in your glass
7. Manually path Water Jet cut file
8. Positioning your glass on the Water Jet
9. Cut & Enjoy

This was a very well-written instructable! Good job, guys. In advance of the Make it Real Challenge deadline, you should consider changing the main image to the finished product only (without the pink panther panel, weighted bags, etc.) It'll bring in more clicks and votes for your entry.

I'm assuming you've entered the Make it Real Challenge, because this would make a stellar entry. You might even be able to get this into the Wheels Contest, as this is, you know, round. :)
