90mm 10 bar pipe

Unread postAuthor: MaxuS the 2nd » Sat Aug 16, 2008 6:43 am

Not sure if anyone apart from people from the Uk will know, but does anybody have any ideas of what will fit in a length of 10bar rated 90mm pipe.

The bore is 81.4mm.

In terms of ammunition?

A typical soup tin is around 75mm in diameter, a few wrappings of duct tape and you've got a good sabot ;)

What on earth do you have in mind? Rebarrelling your tennis ball cannon?

Where did you get hold of that?

I mean, how much did it cost you?

Err. Lol.

Can't talk about it until I'm sure that there isn't going to be a contest.

It cost me £15 for 2m from Hendersons (www.hendersons.co.uk). There were no delivery charges because I live very close and collected it myself.

Anybody know the diameter of a caulking tube?

A caulking tube is about 50mm if I remember rightly.

If you shot a silicone tube and made it burst, it would make one helluva mess :twisted:

:wink: Certainly would, although I'm tempted to fill it with cement.. :twisted:

On the 16bar rated 90mm pipe, the bore would be 76.6mm, which is exactly 3". But on the other hand costs a fair bit more.

lol cement would probably make a mess to, there'll be bits of whatever your shooting at everywhere :)

Imo its better to go for the slightly bigger bore, because its easier to make your ammo bigger than it is to make it smaller.

I suppose so, and I won't have to buy any 16 bar, which would cost the bomb.

I've always wanted to make a cannon to fire pineapples (struck me as a novel idea)... perhaps smallish pineapples? :P

3" is 76.2 mm - so it's not exactly 3"... Sorry, that's just my pedantic side kicking in.

By that logic, every cannon should have a 20" bore, because then you could fire people.
Personally, I love my 20.3mm bores - it just feels "right", and there are lots of cheap things that fit it well.

Does that thing kinda look like a big cat to you?

Lol Rag, I was only going by the two different sized Maxus was talking about, 20" bore would be quite cool though :D

Most of my cannons only have 15mm bore, but there great fun to shoot.
