Throwline launcher

[tim361]

A few weeks ago me and a friend were dead wooding a load of Scott’s pines. Unhelpfully someone had cut all the lower branches off for the first 15-20 metres so had to use throw lines to get a line set in the tree. I’ll be the first to admit that I’m pretty awful with a throw line. Made the weeks dead wooding harder than it needed to be. Had spent some time reading through the post below about which catapult to buy and watched a few videos on YouTube about catapults and came across a video of a guy who had built an air launcher in the states for very little money. After a bit of trawling on the internet I build this below, cost £60 in materials and about half an hour to assemble. Very easy. If anyone wants a cutting list to build it let me know.

Is this made from plastic or metal? I'd be interested in a cutting list ?

Me too please

It’s all galvanised metal tubing. Some of the ones I watched on YouTube were plastic or a metal/plastic mix. I thought to make it last as long as possible I’d do it all out of metal.

Does it pump up on a tyre valve? Looks great

[tim361]

Yes. I drilled the end cap on the air tank part to take a bolt in tyre valve so can be pump up with a compressor or a foot pump etc...

Only other bits you need is a roll or two of PTFE tape and some threaded tyre valves. Something like the first ones in the picture below.
