Glass Oiler Files
Added 2022-09-17 21:46:17 +0000 UTCHey Patrons!
Here are the CAD models and drawings for the glass oilers I showed in today's video. If you have Fusion 360, everything is parameterized so it should be easy to scale to your engine size, or adjust for the size of glass tubing you can get. Enjoy!
As always, these files can be found any time in the Patron Drive as well.

Concerning glass cutting: some types of glass are annealed or tempered and resist cutting, additionally borosilicate glass although common, cuts easier and cleaner than kimax or pyrex. You were correct, the rapid heating from your torch was too fast, heating slower enables the glass to expand slowly, relieve the stress and become less likely to fracture or propagate fractures... hope that helps even a little for next time...

2022-09-19 16:24:04 +0000 UTCYah, water cooling is definitely a good idea for glass, I think. Also apparently keeps the dust down, which is good. I was wearing a respirator anyway, because glass dust is nasty nasty stuff.

2022-09-19 16:23:23 +0000 UTCWhen I was in grad school we had an abrasive cutoff saw in our glass shop. It was a large diameter blade (12" or so?) and used continuous water cooling. Most reasonable thickness of glass would cut without issues but when you got down to really thin glass it would mostly cut but chip out occasionally. I was usually able to cut glass NMR tubes which are 5 or 10mm in diameter with walls that are typically 0.77mm thick.

2022-09-18 20:58:51 +0000 UTCI was wondering if some cooling (plain water) would help with diamond-cutting the glass. Might even help with keeping the glass dust down, you don't want that stuff anywhere (not in your lathe, not in your lungs...). Or would adding water just make a horrible mess?

2022-09-18 19:43:53 +0000 UTCYah, I didn't know about vaping glass tubes. I wish I had! Many folks suggested it though, so I sure know for next time. 😁

2022-09-18 17:13:27 +0000 UTCI'm watching the video now and there's a lot of struggle with glass! Pyrex glass tubes for vape tanks aren't even a dollar each and exactly what this type of project calls for.
