Oh forgot to add -
If the stars, planets and tree's all align correctly I may get another shooting session in within the next few weeks. We will have a special target this time. Not telling what it is, but here's a hint (this is a photo of one like it - our's has steelys and no windows left lol)
I also want some idea's for targets. I'm getting tired of microwaves and food. I have the idea for the 2L bottle filled with liquid hydrocarbons and road flares accidentally placed nearby - but I want others! I keep forgetting to do "power demonstration" shots i.e. how many layers of plywood...
How about some alternative ammunition
3/8" ball bearing buckshot for example...
Shame about the calibre, I would have offered some machined rounds and sabots. As it is anything above 1.5 inches diameter is possible but inconvenient.
Ahh good idea with the buck shot - that will look rather interesting on the vehicle.
I found a good deal on 100 1/2" bulk steel bearings that I just got on the 'Bay. I can make 3 or 4 buckshot rounds (I made a prototype shot shell "wad" and it holds 21 1/2" balls). I'll have some left over for the mighty mini cannon then!
Early HGDT estimates at 10X conditions give me a velocity of 1092 - more than fast enough to pass through sheet metal
I just reran a HGDT simulation of my 8X ceramic ball tests... 1071fps... that's scarily accurate (I chrono'd 2 shots right at 1070fps)
I really want to finish my APFSDS round I will be doing some welding the rest of this week so perhaps I can toss it in the mix. What does everyone think of the tip? attempt to harden it via flame and/or oil - or just sacrifice some old drill bits? Need a Sabot system too... oi vai Hopefully a disc/cylinder with a push rod/holder will work sufficiently (dart shaft will be constructed of steel tubing)!
Well after welding all sorts of items for Xmas gifts, I decided to make myself some.
3 different sized darts - all with solid steel tips fully fused to a hollow shaft with sacrificial fins (I made 2 sets for each projectile in the rare chance I get to re-use one of them )
Can't honestly say that I did a CP to CG comparison to make sure they are super stable - but I won't be shooting them too far. I plan to use golf balls cut in half and screw on a retaining bushing to them that inserts about 1/2" into the rear of each arrow for the rear portion of the sabot. Not sure what to do for the front yet unless I can use the fins to take car of the centering...? hmm
Either way - I finally have some nice darts, I'm going to oil quench the tips soon with my O2/Ac setup and a pot of used motor oil wish me luck!
Very nice. Now it's definitely a Merry Christmas for you! I'd be interested to see how well this performs against the engine block of the target you mentioned earlier in this thread.
*fap fap fap*
How about three small radial bolts at the front to take care of centering?
can't wait to see these in action
JSR - not sure what a "radial bolt" is to be honest - mind doing what you do best and posting a link?
Well I went through with the oil quenching today - it went pretty smoothly until I got to the monster dart!
The first two darts (small and medium) after the quenching process:
The flame heating:
Getting it cherry red:
(the oil got so hot from absorbing heat from my massive dart - that it caught fire, well I had a lot on my hand at the moment so I kept cooling the dart thinking the fire was temporary like the first two - it wasn't! After about a minute, the bucket caught fire, and with my boy scout knowledge in hand - I knew not to throw water on that crap lol. I looked around for any loose dirt like material, but lo and behold it's winter here and all that dirt is frozen! I finally found some peat moss and through it on the oil fire, but not before it had burned the walls of the container down and created a mini superfund site in my backyard! For those that don't like superfund sites in their backyard - I'm with you... I scooped about an inch of dirt from the whole site, which captured all the oil thankfully and put it in a trash bag.)
Now my arsenal consists of the following projectiles (with weights!)
Some engine block penetration would be nice.
EDIT - and I used to live a few blocks from a superfund site, although it was mainly creosote and not oil.
I mean screw a couple of bolts into the front to act as supports to keep it centred, with the same orientation as the fins.
Another option is something like this if you have a lathe handy:
Worked well for an arrow inthis.
love the canon but i think that it is cool that you can get a golf ball up to speeds that would rival a 22 cal shot thouh i hope im nowhere near that thing if you miss is what i would look like if this whent flying next to me and then i see a mailbox acrross the street explode
Yes. Exactly. :tongue7: :pottytrain3: :homework: :angel13: :3some: :cya: :cyclops: :compress: :blob8: :icescream: :kermit: :sign12: :toothy2: :violent2: :spam1: :smurf: :faroah: :blob: :ky: :occasion5: :occasion6: :hiding:
Ughh... Currently living in a large city... No way in hell I can continue work on this hobby except in the virtual realm for the next year or so. By then I hope to be moving to Colorado/somewhere out in the rocky mountains... then its GAME ON!
You're just about ready to go ape sh*t once you sail across the pond on your epoxy lifeboat aren't you jack
LeMaudit has kindly conceded me some time to make a 4" PVC pneumatic just to get it out of my system before concentrating on more commercially viable paintball/airsoft projects
You should make darts/ misiles that fit over the barrel and have a perfect seal or somthing of the sort, but make sure that you have a blast guard.
