Tables, no. This is just a prototype.... But it would be really nice if it would. Also my friend has some 200lbs test Kevlar survival line for me :D
Banjo, I did to and tried to climb a tree but unfortunately because I lacked any meaningful upper body strength I fell on my a**.

Project batman, mini build log

My latest project, something inspired by batman :) . A grappling hook launcher that fits in your pocket (or utility belt:). Let's cut to the chase; here's what I've got so far.

Shard, thanks for the chart. I cant read all of it right now because my computer is retarded but i can assure you i will. No pun intended if I brazed the but joint and get full penetration it should be fine for metered propane and low mixes (building a metered combustion with hybrid capabilities)

You can use a thick (at least 3mm and no it does not have to be 1 piece) piece of rubber or neoprene. I found (with my cane gun) that thin flexable pieces of rubber have a tendancy of being ripped off the piston and getting lodged half way down the barrel (such a pain to remove flexable greasy gaske...

when brazing cast iron to mild steel (fitting to pipe) no post heating is required as long as i don't get it to hot correct? Also would brazed joints be suitable for a low mix hybrid (up to X4)?

Thanks.

I can just use soft but tight fitting projectiles so as to not damage or erode my barrel. Either way I'm going to have fun with it :D

But brushed copper is so sexy..... i think for now im just going to have to do a tight sabot or put wadding both in front and behind the projectile. If i do "dress" it up a bit i will probably bring the chamber to the same diameter as the fittings, paint it and port the barrel to give the look of an...

Thanks, I like the look of the copper... I could roll a thin sheet of copper (Im in a welding shop 5 days a week so I get free stuff all the time) between the joints to give it a cleaner look and finish the schrader cover, Also I considered porting the barrel on 2 sides to give the appearance of an ...

Copper air cane

So this is my first copper gun and first serviceable piston (my unserviceable piston destroyed itself on the 2nd shot :cry: ) I havent done much testing because of leaks and ghetto pistons (I have a non ghetto piston that i will share when I open it up again). Overall this is a gun of many firsts fo...

Jsr I may be slightly ahead of myself but I do have a few interesting piston related projects at various stages. Also I kinda considered wyz as a higher level because of the really good work I've seen. Guess il stop being the prick I've made myself to be :D And catch up of all the stuff I missed.

fine maybe this post was a little miss guided but as the largest online spudding community with 10,000+ members (i realize most aren't active) I figured that some of the lower to mid level spudders would try and take the reins a little and bring some new ideas or new takes on old ideas to the table ...

Innovation?

Is it just me or has nothing really innovative been posted lately? This lull is driving me and possibly others crazy. That being said, spudders, get your s*** together and build outside the box. Also for those who are going to tell me that im being a Hippocrate because I haven't posted anything outs...

lol, I searched bolt action coaxial and came up with nothing XD. Quark, its kinda funny how we came to the EXACT same solution.

I havent had polish vodka but i got a 1L bottle for 3 euros when I was in germany :)

bolt action coaxial?

heres my design for a bolt action coaxial to be used for 40mm projectiles (filled ping pong balls and squash balls)

the main problem I for see is making the piston due to my limited machining experience and/or access to a lathe

I can redo the drawing if needed (my computer was acting up)
