This...is...Brilliant, I'd seen some attempts at making blast doors but this is the most perfect I've seen so far, they actually work, great work with those gears, especially the ones spinning inside your brain, great job!

Wow. That is a very impressive piece of technique. This is one of the best working creations I have ever seen!

Chris really needs to see this...

totally awesome!really great!looks very blast proof

you are crazy good

Wow! that looks like something Lego would do! amazing job.

This rocks my socks off! You have made possibly the most awesome :ego blast doors I have ever seen! Excellent job!

Awesome!

A simple, yet very functional opening mechanism. Fantastic work, keep it up!

Holy moly. This is genius. I actually thought of making one of these before, but I didn't even thought of making an opening mechanism. And Typh, I believe this is quite simple of making. You don't need instructions. Goo job Cole.

PURE PURE GENIOUS!!!! this is so totally awsome, the fact that the doors are gear-operated is just epic. im curious though, exactly how did you get the doors to connect with the gears?

Great Job
