Spot on SugarJ.

The Ice is just to keep the Iso from evaporating.The Iso the glass is in , is hot to accelerate any reactions.

This isnt the cold test , just the compatibility test.If it survives this , it's on to part b of the test .

This will involve mixing silica sand into the epoxy then bonding two longer pieces of glass together , and testing the 'shear' with dry ice.

OMG! It's Bill Nye the Science Guys!

Jeeze, who would have thought modding would require such chemistry knowledge!

Way over my head, but sure fun to watch!!

hehe

YES I am a science geek.I admit it.....hahaha

I wanted to be the first kid on my block to build a megawatt class laser...(that's a diff worklog)....

---------------

Last night I maintained 72 C on the Iso test rig for 2 hrs , and let it sit till about an hour ago.I am starting thermal cycle 2 this time to full boiling for several hours (82 c)......

So far so good.....I see no evidence of problems so far.I'll be doing random thermal cycles for the next week....then well see.



ps........I own bill nye.

I was on vacations last week with no Internet access, I missed this thread so much. I cant believe how I am way over my head here, but everyhting seems so dangerous that I have to read it all and try to make some sense of it.

Yea, most of this is way over my head as well, but man it sure is interesting and fun to watch.

LOL, that is awesome.

good luck this will be a good science project for me :) ahah jk my dad is scared i will burn down the house building a plain old computer XD

[BrainEater]

heheh.

Don't get me wrong , I love Bill Nye.

--------

My glass/epoxy test substrate has been in Iso for 4 days.Several thermal cycles.I have yet to see any obvious problems....seems fine to me....tests continue.

--------

I actually found a pump rated for Isopropanol....

Hahah....$2600 , I don't think so.

--------

A good friend of mine , cls||Hades came up with a really good idea for a pump .
An 'auger' bit for a drill , inside of a pipe , rather than a prop.Not only would this allow me to find bits-that-match-pipes , but Auger pumps are what they use to pump viscous materials like concrete , so the viscosity change when the iso hits -70 c wont be an issue.

!!

I'm looking into a test rig for this right now.

----------

I just hassled my 3/4" flare fittings supplier again.Still no word.

That's a hell of a good idea, actually. Drop a 15/16" bit into a 1" ID pipe, or a 1" bit with a little shaving done. Cheap!

Don't forget to stress-test that sample, 'cause micro-fractures may not be visible to the naked eye.

Umm, 3.0charlie, you know how he stress tests things, right?

But yes, I'd do a destructive test on that. Put it in the vise, snap it off. If the glass breaks first, you're probably ok. If the glue seam goes, back to Plan B.
