an old professional paint shop calculation: booth opening area in sq feet X 100 = cfm so for a booth with a 20" by 20" opening the area would be about 2.75 sq feet, so you'd want a fan rated at 275 cfm. That may seem a bit extreme, but that's what's recommended for professional paint installations, so you could get away with a bit less. I cheated a bit and am using a modified 12 volt power supply to run a shrouded car radiator fan pulling about 900 cmf

Man...I thought I was the only one that did this to my models pre-paint...difference being that I use the cheapo paste style toothpaste...gives the plastic such a nice lovely finish for primers...and like you said...every nook and cranny.

it's basically going to be a week long road trip with the show at the end, so the model will go into the hotel room at night. I have been mulling over ideas like packing it in a box with some freezer packs just to keep the temps down in the box, but then I'd worry about condensation. I'm probably way over thinking it, but North Carolina in the summer tends to about 3 degrees short of He** and I'd be crushed if my first ever show entry was "droopy" when I got there.

Minor threadomancy here...I'm preparing a model for a show in July as part of a week-long road trip...what about heat? Has anyone experienced heat damage to a model in the trunk of a car over time? I'd hate to get there with nothing to show but a melted plastic blob...

I'm looking for aftermarket or kit sources for putting wide performance tires on a 49 mercury...but with a wide whitewall. It's a custom build with a turbo Porsche V-10, so I'm talking mini-tub width on the rear...but I don't want the super skinny sidewall like you'd see on most performance tires. But I also don't want the high sidewall look like stock...somewhere in between. Everything I can find (kit or aftermarket) is either wide tread and skinny sidewall, or enough sidewall but narrow tread. I am toying with cutting a pair of leftover kit tires down to make one wider tire, and then cast it, but it isnt going well. Any thoughts? Here's sort of the look I want...not too much sidewall, but enough for the stripe... What I DON'T want...

I still haven't figured out how you got them to disassemble the real car so you could take "in progress" pictures of individual components...good job though with photoshopping pictures of your hands in front of real car parts.

How long also depends on tank size. I think the most common tanks are 5 pound and 20 pound, but they have other sizes too. A 5 pound won't last nearly as long as a 20 pound, but a 20 pound CO2 tank is a pretty big boy...heavy too. So when you decide what to get, figure in the trouble you'd have storing it and taking it for refills.

Stick with CO2. Nitrogen tanks are filled to a much higher pressure (something like 3000 psi), so if you knock it over and break off the neck, the tank is going through your wall, your car, your shed, your neighbors house, etc.

I don't have any pictures yet, but how about a Porsche Carrera V-10 and a GM Auto in a '49 Mercury custom?

I, literally less than a year ago, sold a '55 Coronet that was a virtual twin to the one in your profile pic, except mine was the reverse colors (blue with a white hood)...beautiful car, but couldn't keep it because of family situations. Also, fantastic work on the Firebird.

Totally off topic...what's the car in your profile pic?

I actually use the grit on homemade tools mostly for cleaning up metal gaming minis. As for plastic, it works well for small detail parts and engines and whatnot, since you can make small tools in different shapes. I also make my own padded sanding sticks. I use what they call eva foam...comes from the craft store or the craft section at walmart in sheets...I glue down a whole sheet to the back of a sheet of sandpaper, then to the back of the foam I glue down a bunch of popsicle sticks or bits of wood...let dry and cut up. They don't last as long as the pre-made kind from the hobby shop, but they are a lot cheaper, and I can mass produce them.

That famous auction site...search for tumbler grit. I got a little bag of 400 grit that has lasted me for years with no end in site. My favorite is to put glue on the ends of toothpicks and stick them in the container and let them dry, but you can use any shape you want.

I see your 485cfm and raise you 549cfm for about $15 less...now I know where my Christmas money is going. http://www.amazon.com/R7-RB445-Rotom-Replacement-Blower-Dayton/dp/B005RAHEG6/ref=sr_1_cc_1?s=aps&ie=UTF8&qid=1419284173&sr=1-1-catcorr&keywords=r7-rb445

This thread is over a year old...are you still producing these or something similar? If so, what are you charging for them?
