Another convert to the dark side

Unread postAuthor: JDP12 » Wed Aug 11, 2010 4:01 pm

well I was at my local hardware store, and guess what I stumbled upon--- marine epoxy. I got 1/2 lb of it, and am hoping to begin my descent into the epoxy batcave.

Plans are in place to make a blowforward action in a syringe tube...

Hmm.. .after inspecting it, it says no runs or drips... so my worry may be it might not run well for when I'm attempting to cast stuff or epoxy a syringe in a tube.... We'll have to find out I suppose.

Damn, looks like it is an epoxy paste, and not a true epoxy... I dunno.

1st off even if you could find enough air storage to get you that deep the pressure would crush you to the size of a single cell organism. 2ndly you would never find the entrance, it pops up in random locations of jsr's choosing.

But since you made a epoxy effort, he just mite, if your lucky stop by and visit you/this thread.

What was the cost difference between the marine and the others of same weight?

Or that's what we think. No one has ever seen a JSR in the wild actually entering his batcave, but experiments has been tried on the ones that was captured from their favorite epoxy supplier. No luck so far.

But: What is really the difference between "normal" epoxy and marine-grade?

I hope I'm lucky...

It was $10 for what I purchased. Not sure how that compares to other things in the same weight.

I'm afraid the stuff I have will just be like a paste as that's the way the pictures seem..

I believe the marine-grade is more durable and strong, as it has to be able to keep up its integrity in water

Efforts are being made to categorize the natural behavior of the JSR. We believe it to be an adhesiv-vore with nocturnal tendencies.

marine epoxy will not shrink, whereas many epoxies will. it is really designed to be able to seal and LAST. and judging by his lack of comment, I am going to assume that all the epoxy finally crossed the blood-brain barrier and turned him into a great big 850 PSI+ piston valve. I'm sure it's what he always wanted really. :angel11: :angel11: :angel11:

this thread made me lol

if the epoxy is thick you can heat it up a bit to thin it out, i do that a lot to make sure it gets in all the tight spots. might be hard if you do it in a syringe.

Well I'm going to return that stuff and hopefully find some more viscous epoxy.

How are you heating it? Fire hazard??? Warnings all over epoxy containers.

I think you want to find some "less" viscous epoxy.
Refer to the definition of viscous.

I go on vacation for a couple of days and return to find I have been transfigured into spudgun parts like some eternal potato cannon messiah :roll:

In years to come the myth of JSR will become Stig-like in magnitude and disparity from the truth...

Anyway, on to the subject of this thread, yes it does indeed seem to be a paste which means it's not very useful for casting. As has been suggested, heating might help to thin it out but it might not flow enough to fill awkward moulds. Still, it's perfectly good for endcaps and probably pistons if you work it correctly.

As dewey helpfully pointed out, for casting less viscosity is ideal ;)

My bad sorry boys.

And yes JSR you probably are a potato cannon messiah.

Yea I'll have to try and find some new epoxy... Although I kinda doubt I'll be able to work on cannons in my dorm room.... I can just make extensive plans, which I am already doing
