The right size of rubber ??

[Ollybean]

No no, its not what your thinking. I am making my own "big shot" and would like to know what kind of rubber to use and its size, i.e. OD, ID and length. I have never seen a real live one and its hard to judge off any photos what I need. Any info or idea is welcome.

i was going to say, it's one sizes fits all my friend:lol::lol:

 

 

i presume you mean the sling shot?

 

 

i would have thought a 1/2" surgical tube would be ok?

For thirty quid, why would you make your own?

Big Shot - Rubber-Tubing - Catapults - Rope Installation - Ropes

When I google them they come in at £150 to £180.

Tried a black widow school boy catapult? 15 quid from the local shooting shop and does the job nicely. Also packs in the climbing bag. Can also be used to fire a bouncy ball at the vicinity of the groundie having a crafty fag and text when he thinks you can't see him. Obviously that is hugely unprofessional and I would never do it.

Be a tad careful with whatever you make, I heard of a lad that put a bigshot head on his own pole, it snapped and put him in a coma!

You asked about rubbers and that's where the link takes you. Making your own is reasonably simple but the rubbers would be the hardest part. The rest is just a bit of simple fabrication and a suitable pole.

 

Unless you have parts you can re use I think you are going to struggle to bring a decent job in for much less than the list price

How painful is it to replace the rubber on the head?

Thanks, I did not realise that was a link to the rubbers,

You could use a few strands of something thinner to make up a stronger resistance. Theraband flat or tubing gives good results on catapults and is available in different grades.
