I never thought about cutting the base edge of the mask :) I always just sand down the excess thin bits with a dremel until it gets to a smoother sturdyness. That's very interesting ^^

I try not the dremel unless I have to since it kicks up so much dust and has to be done in a air chamber heh

running shop vacs with the hose near what you're sanding are magic for that

but yeah cutting with scissors or blades is sooo much more pleasant..

Yeah I actually have a really cool box with a hose attachment and a plexiglass viewport for dremeling. Works super!

lol. I have a cardboard box with a hole in it

I upgraded ;D Far saw my cardboard box outside to be take to the trash and was like "Aha!"

luckily I'm working in a garage right now on a work table :) so it' easy to sweep up all of the dust X_X I also have a respirator and a full face vintage war gas mask. :/ helps sometimes. but I end up getting dust all in my hair it's so not... fun. one of the things I hate a LOT about the process x__X and going back and forth between the cutter attachment and the sander attachment ugh. I also tend to go by the seat of my pants so I end up just grabbing things/ chemicals and such without really preparing to use it beforehand (gloves, apron etc) I've ruined all of my "used to be favorite" clothes because of these resin things. I really wish I didn't do that. and I just need to get a good apron.

Whoa! How useful! Thanks for sharing!

also I feel like I should say something about the glove thing. I saw Q's LJ fursuit post before this journal, now I see what inspired her to post it

I think you're crazy for not wearing gloves. but if gloves cause rashes for you that sucks. wearing so many pairs of powdered nitrile gloves a day makes my hands feel terrible and want to fall off, but it's better than having to scrub off resin. does that liquid glove stuff actually work? sounds like it would be unpleasant to get off your skin too. is it?

saying the resin contains no hazardous ingredients is a bit scary and misleading, and personally I would remove that bit. but you did link the MSDS, that was good

According to the Section 2 - Hazards Identification on the MSDS, OSHA specifically say "not hazardous" so I just quoted as stated.

I much prefer a non physical barrier when possible. Keeps me 'closer to the action' and washes off easily (though I prefer to try and not spill in the first place). I'm not sure what would be best for you considering how much you work with resin though - my exposure is really rather slight given how few masks I cast a year. I picked up some blue liquid soap from smooth-on that actually takes resin (and foam) off really well. You have to scrub a bit but it's worth it to me ^^

yeah I've got that soap too. I was super surprised it works really well but doesn't kill my hands

my section 2 of the 65d MSDS says "harmful by inhalation, irritating to eyes, respiratory system and skin, limited evidence of a carcinogenic effect, harmful; danger of serious damage to health by prolonged exposure through inhalation"

oh shit I see what you're saying. The US version of the sheet does say it's 'not hazardous', while the EU and Canadian one has all the warnings. huh

Really?! Wow that's.. interesting.

Well it still points out to use a respirator (I do) but that's it's merely 'irritating' to skin which is what gloves are to me so well I'll pick my limited protection over getting hives I guess XD

do you think it would be use to you to wear those thin cotton gloves underneath nitril ones?
there are also unpowdered nitril gloves out there, in case your issue is with the powder. or those extremely cheap plastic foil gloves like you can get at the gas station. not very sturdy, but better than nothing. I also have them seen used at butcheries and at Subway's.

Any idea where to get the cotton gloves? I'm pretty intent on not losing dexterity so they have to be very thin. My allergy is to my own sweat actually lol. Gives me hives which is serious discomfort.

I have seen some at a construction market. I have also seen comic artists using them so their hands won't stick to the paper while inking/colouring. they are a bit thinner than an average cotton undershirt and fairly stretchy. you will sweat, too, of course, but maybe it'll be easier on your skin.
I know what you mean. I mix up car paints for a living and occasionally I have to use them nitril gloves, too, and after an hour or so my hands's skin is swollen with moisture. :P

Interesting to see, I personally don't use a mold release and I usually wait for it to cure because I have had accidents where the mold deforms if pulled to early.

Mold release is not required but will extend the life of your mold.

You can see in he video that the head is stiff - there is no danger of any parts of it deforming :) And if they did then that could be put back right with a heat gun.

Might have to get some mold release then, I use platinum stuff so its very durable but I have had rips before sadly.
Going to have to look into a heat gun XD Ive been meaning to buy one for months, especially since my college courses are moving into metal working and a heat gun comes in handy for that stuff sometimes.

They are pretty awesome :D And really not that expensive!

Yea they have sales regularly at harbor freight on heat guns, but great video =D

So to make the mother mold you need to use plastine clay to make the sculpture?

You can use that yes :)

Nice video!

You could probably make more molds and do more at a time, since they seem so time consuming for doing one at a time... though, unless you plan on selling blanks regularly it would be a waste of time to make more molds. X3

I do sometimes (I make a canine and a feline at the same time) but the issue is if you leave one alone too long the resin might coagulate in the bottom of the mold and ruin it heh. It can be hard to balance the needs of both molds.
