lol .. close enough... its caliber happens to be tennis ball size since potatoes are not consistent.. oranges also 'apparently' work if smaller size .. although .. i was told that oranges can and do disintegrate once outside the muzzle if too high a charge of 'start ya bastard' (aerostart/ether) is used!!...

also... apparently maximum distance straight up with a new and tight tennis ball is in the region of 400-500 metres?... at heavy 'charge' levels.. 

cant get start ya bastard here in the us.  engine starting fluid is avail. tho. but dammit. like the name lol. now what about calcium carbide?

Lighter fluid or hair spray works as a propellent. Just jam a potato in the end for a tight fit. Potato's turn into mashed potato's when they impact.

Used in railways but its mainly the purpose it's used for the job it performs gives the biggest clue to what it is

[yamahonkawazuki]

Yup ive used that before.  but so many times, ( like on the goped) id get aggrivated, BP thru roof, and yell out "START YA BASTARD" weve got similar stuff in us, but not called that 
ive 4lbs give or take a lb. of calcium carbide. a bit of water = acetylene gas and of confined, a small bomb

[yamahonkawazuki]

nehow back on topic. is this item used to keep things from moving?or sliding?

[slipperymongoose]

On the right track Yamma it when fully installed it prevents movement

[yamahonkawazuki]

vertical or horizontal?

[slipperymongoose]

Rotational

[Paulcet]

Reminds me of truss plates.

[oldmech]

is it an oversized lock washer/tab device for a bolt?

[slipperymongoose]

Old mech has it. It's known as a lock tab tab plate. When a bearing is I installed onto the wheel set the bolts go into the three holes and when they are torqued the tabs are bent up onto the sides of the head of the bolt to stop them undoing.

[oldmech]

here is the next one. there are Phillips screws, straight slot,torx, and many others. what kind is this? even though it has a hex head also like a bolt. it is still considered a screw since it has no grip area and threads all the way up.
