    Looks great nice work!

    Some people were using dental floss when I first started recommending waxed twine.

    Sorry coming back to this stuff, I have just remembered I tried something similar and found it broke after not so long. Waxed twine may not be cheap but it's well worth it.
  4. Sheffield Catapults
    That stuff looks fine, however you will notice it will start to cut into the Theraband with it not being waxed. Get yourself a block of bee's wax and run the twine through it in a sawing motion until covered

    To be fair I think the only resemblance is the handle, his looks a lot like one of Bill Hayes's slingshots which he shares the design openly with on the slingshotforum.com.

    If you are just target shooting then one strip of theraband gold is adequate to shoot 9.5mm steel with, there are varying tapers and lengths you can try out until you find one that suits you. Using bands that are too powerful for your ammo will not result in faster speeds, they will just be harder to draw. As for the best oil, it depends what you are looking for in the finish, if it's just something to bring out the grain then I would choose a danish or tung oil which can just be applied by cloth. If you are looking for something that is more durable then a poly, CA or hard wax oil would

    There are a few variables you need to take into account, like the environment the rubber is stored/shot in. Temperature plays a big part in the life of rubber, so does exposure to UV light. Covering rubber in talcum powder helps protect it from some of these elements! There is also whether or not the bands were tied using a jig, and what was used to tie the pouch end with i.e rubber or waxed twine. Peoples choice in ammo will also affect band life, more so the people who shoot objects like stones which tend to nick bands and cause them to rip. It looks like you are using a lot of rubber t

    Take a look at some of the ones we have for sale, our Hammer Hunter design is very popular with hunters. All the best, Jim.

    Hi Gaz, I replied to your message on Facebook a few days ago mate Check your 'Other' message box folder.

    Lanyards are for girls

    Ahhh, this is what's generally considered a wrist brace:
  12. Sheffield Catapults
    16mm is what most use for pheasants as they are such a tough bird. As for adding a wrist brace to a flat boardcut, how do you intend he does that lol?
  13. Sheffield Catapults
    Good thinking! Saves you having to learn the different trajectory of a different weight trajectile.
  14. Sheffield Catapults
    £8 for 100 steel 9.5mm's is a lot mate!
  15. Sheffield Catapults
    Good man, pebbles have a tendency to come off your bands which often causes them to rip.
  16. Sheffield Catapults
    Using objects that aren't round (like pebbles) are likely not to shoot straight at high powers like with Theraband Gold on your catapult, so be careful!

    If you want comfort check out our Hammer Hunter Elite, it's a bit more money but it makes shooting heavier bands much more comfortable

    Marine grade ply is fine

    MDF isn't very strong, it's also no good when damp and the dust is very harmful which makes working with it unpleasant. We have been through this before BPR: http://slingshotforum.com/topic/20773-mdf-for-catapults/

    Tubes are good, especially in cold weather as flats are more prone to tearing in freezing conditions. It's down to personal preference, I just prefer flats.
  21. Sheffield Catapults
    I prefer Theraband Gold, it has a decent life span and produces great speed and power.

    I wouldn't use an oven to dry forks, it will more than likely result in the forks cracking. Some people use microwave ovens but that can easily result in a broken microwave as I once found out. The best way to dry a fork is to cut it a little longer than needed and to dry it slowly, placing them near a hot stove is a good way. Cutting them a little longer helps as if the fork does split at the ends then that section can easily be cut off.

    Be careful with the design you choose, if a design is bad then even using plywood can result in a broken frame. Plywood is good to start with as it's cheap and pretty strong. Once you have got a bit better at making frames you can opt for more expensive hard woods and experiment with laminating them.
  24. Sheffield Catapults
    Avoid soft woods and MDF.

    Defiant 5.52 are great in the BSA barrels I've had.
