I found a local steel supplier. What am I looking for? Square or rectangle? Thickness?

I highly recommend you visit your local recycling center. That's where I get all of my metal for small projects. I buy stuff for next to nothing, essentially a bit over scrape price.

Wonderful job on your prop! Your build is the core for so many prop possibilities, it gets my mind whirling. It just proves that I have so much to learn about pneumatic props, controllers, etc., never mind the whole welding issue! Keep up the great work!

I used 1x2 inch tubing for the base and the 2 uprights that the nose of the cylinder attach to and 1 inch square tubing for the center rail, both the pivoting uprights and for the extender that the spider attaches to. To tell you the truth, I don't remember what thickness it was. I'll check with Ron and see if he remembers when I see him this weekend.

Did you miter your base corners for welding or overlap them? The welds don't look like they are 90 degree angles, but I don't see any openings from the sides.

oooh so shiney! good job on the build!

Okay now. Halloween is over and I m ready to see the vid of the spider in action scaring the crap out of the kids.

Totally mitered those corners... Nice welding... Even ground off the beads! So vain! lol good work!

I'm hooked... I've been sitting on this spider for like 8 years and looking for something to do with it... a spitting jumper might be a good addition.



All the steel I can get from my supplier here is 1/8" which is good and solid but man some of these props get heavy! This spider is about 3 lbs of foam and latex so I'd probably need a cinder block on the back of the frame.

The nice thing is that damn spider has been a static prop for years so they kids wouldn't expect it... lol

*** as an aside considering the cost of those flow controls from your online store ($8 to $11 each!) I'm starting to think these kits from Frightprops aren't such a bad deal...

Those flow controls that Halstaff recommended are $11 for a pair. I just picked up a couple pairs.
