plastic thickness

[Darth Voorhees[501st]]

This is probably a dumb question lol.......So i went on TAP plastics to price a sheet of ABS plastic, i want to get .80 ...but they only have 3/32" listed. what is .80 in inches? is .80 the gauge?

two of us are dumb ?

lol...maaaaaybe !

[sve5mh]

yeah so im lost too....i tried gooogling away...but im as lost as the next....hopefully someone comes to the rescue on this one..haha

You said .80, dont you mean, .080.

 

.80 equals 4/5"

 

.080 equals 5/64"

 

Hope it helps.

BTW, 3/32" equals 0.0938 which is just a little over .090

Is that AWG gauge? Or metric?

I'm assuming AWG so try googling that

 

It's usually an expression of a fraction of an inch

 

Sorry this doesn't paste well

This is the one you want

whoops..yes i meant .080. thanks guys! i dunno why they only have that one thickness listed for white ABS. Im going to be building a small Vac-table, nothin crazy, just a "shop-vac" one. Im gonna fiddle around with some smaller stuff, but would like .060-.080. basing that off of my old AP armor which is .080 i believe. .090 will likely be too thick to get any nice detail on a shopvac set-up. Does anyone have a US source for white (and black) ABS sheet in these thickness's ?

[elkamino]

When vacuum forming helmets I use 0.060" for the faceplate (to capture the detail) and ears and then use 0.090" for the dome. 0.080" is an oddball size with 0.090" (actually 0.093" based on 3/32" conversion) being the most common. It also very hard to find ABS that does not have "haircell" which is the grainy pattern on one side as well. But contrary to most's belief the haircell does not reduce the details you can get vacuum forming....its the humidity factor. ABS is highly susceptable to humity and moisture retention. Most plastic manufacturer's will say you should bake the sheet goods at 275 degrees F for 24 hours to remove all moisture from the product.
