Smooth Cast 300 is a good product for this sort of casting.
It "snap cures" to a rigid plastic (meaning that it has no semi flexible stage) so sag and warping should be less of a concern.

Hope that helps

Super 77 applied lightly to the fabric just might hold the mesh in place.

I have to agree with Chacal about the filler idea. At my last job I had to develop a lighted button for an amplified speaker. 8 LED's behind the button. 4 white for power on status switching to 4 red for overload status. We were getting hot spots no matter what we did...we tried frosting the inner s...

Thank you, my brethren, for all for the suggestions.
The challenge has been met and well defeated !
The Saran Wrap has performed superbly.

I bow before the mighty Aves for it is truely the master's putty!

Can any of you Wizards of Aves point me in the direction of an effective release agent for Aves Sculpt? I've tried vaseline and nearly messed the bed ( if you get my drift :wink: ) I'm trying to fit a tenon to a slot by making the slot oversized and packing it with Aves then pressing the part with t...

I'm partial to "Plasti-Cote's" Sandable White Primer.
It's lacquer based and dries quickly.
Very smooth when applied right.

If you need high gloss...follow up with 3-4 light coats of Future and polish, polish. polish.

Yer welcome Kylwell....

I found that the surface tension of this stuff would not let acrylic paint flow through till I touched the underside.

Enjoy!

OK, screen has (finally) been shipped.

Craig, Kenny, Rob, Brent and Andrew......

Watch the skies.....

Lt ZOmBe, Kylwell, and the good doctor....I took a look at my supply and I have to say...this stuff is wicked fine stuff. I'm going to try straining some acrylic paint tonight and check the functioning. ( It may be too fine) If it functions admirably...I'll let ya' know tomorrow, early. As for avail...

Kylwell...defining away....by "stuff", I mean very fine mesh stainless steel screen. I'm going to the old factory today and I'll grab a bit so I'll have more on hand after today. This stuff should work great for straining. I'll be sending some to Lt.ZOmBe today....let's wait and see if it'...

Lt.Zombie....I can help you with that one....at my previous job we used tons of the stuff as a waterproofing screen on speaker cabinets. I just happen to have some sitting round just hanging out. :wink: Send me a PM with your ship to address and I'll get some out to you this week. Free even ! Yea......

Have you tried using WED clay ?
Find it at Michael's ..... made by Laguna...about $ 6.00 for a few pounds.
Get the gray stuff.

MUCH easyer to work than other clays ( I've used them all )
Works super easy...cleans up with water.

On the other hand...have you considered doing a cut mold ?

Here's a lead for ya' Core material for composite construction is often a honeycomb design. I have seen just what you're describing...it's only a question of sizes available. I'll bet that a short while google'ing "honeycomb core" or "composite core materials" would provide a wor...

You didn't knick into the tank itself did you? I'm just wodering what that might do to its structural integrity. Good idea with the mold release. Dennis I was a little concerned about that very thing when I read this post. Had a thought...what about setting a pc. of strapping of some sort ( metal b...

Macfrank ..FYI...both alcohol ( the stuff leaching out of your tin cure mold) and acetone are effective solvents for epoxy. Either of these materials in your mold will cause the issues you've been dealing with. Also, epoxy is a heat set resin and silicone acts as a heat sink..robbing heat from the ...

Plasti-cote's white seems to have the finest "grain"
Far smoother out of the can than any others I've tried.

Thanks tons Brian.....just what I needed

Truely a jedi master of the styrene reserve !

I picked up a Fine Molds X-Wing at W-Fest ( thanks Linda ! ) and when I got home I had a chance to examine it. Surprise, surprise....the instructions are in Japanese ! :shock: The build is no problem ( who uses the instructions anyway :wink: ) but the paint chart is totally non decipherable. :? Is t...

Sounds like a case of cure inhibition caused by an adverse reaction between the resin and silicone. You are using "casting" resin and not laminating resin right ? Laminating resin is supposed to stay sticky so the next layer will bond. Casting resin is more like gel coat resin...it has som...

Don't forget about heating the molds.....it will help

About 1/2 hour in an oven set on the lowest setting.

Keep in mind that the silicone robs heat from the resin... Heat is what cures the resin....the catalyst is there to create heat. Also, you can get a negative reaction from the silicone as well.( Thats why I use platinum cure silicones for clear parts...no alcohol ) Standard silicone gives off alcoho...

Umi...I finally got very good, consistent results using a casting resin from LBI, inc. 973 North Road...Groton Ct. 06340 It's called 303 clear casting resin I had to do a good amount of experiments to arrive at the proper resin to catlyst ratio to ensure a clear cast as well as a complete cure. I fo...

If you are speaking of a polyester resin ( the type used with fiberglass ) then too much resin will do a number of things.... 1) Too much heat will be generated causing the resin to shrink exsessivly perhaps even cracking from internal stresses 2) The clear resin will get cloudy 3) the heat generate...

I coat standard housing foam ( polystyrene or EPS ) with Smooth-On's sc-300 fast cure urethane...works really well...it cures to a sandable finish in 15 min. or so.....you can mix and paint it on with a foam brush doing small areas at a time...it bonds to it's self really well. I have also used it w...

Most welcome

Smooth-On sells a material called Ure-Fil.
Excellent filler for Roto-Molding or slush casting.

Not too much impact to the resin when it comes time for sanding.

Hope this helps ya'

Give it a try....
