    How do you determine the thickness of the fork material? Which is better, plywood, (multiplex), or solid wood? Or are does it matter what you choose? Does anyone use a router to round the edges or do you work the wood down with rasps and sandpaper?<br><br>Thanks

    Well, plywood or multiplex makes a guaranteed strong slingshot and is pretty cheap. solid wood can make very nice slingshots too, but it trends to break along tht grain tho. Using a natural fork doesnt give this effect and can give some great grain paters. I use a rasp and sandpaper, but i know gamekeeper john uses a router. The thickness depends on what i am going to use the slingshot for, heavy bands will need a thicker, stronger frame. <br>

    Thanks for answering so quickly Onnod!<br><br>I plan to use one band of theraband silver per side. I have never done anything with any of the therabands. So, how thick would you recommend that the fork should be? 19mm? Or could I go thinner, say 13mm?

  5. Something like <a href="http://www.amazon.com/s/ref=nb_sb_ss_c_0_3?url=search-alias%3Dtools&field-keywords=circular+saw&sprefix=cir%2Caps%2C315" class="postlink" target="_blank" rel="nofollow">these?</a><br><br>(It's the amazon page for circular saws, or by sawing machine did you mean a free standing model of saw?

    i would go around 18 to 20 mm, this is safe and comfortable to hold, you could go thinner but this will only reduce the comfortableness and if there is a minor failure in the wood it can crack more easily. if you aren't sure about you slingshot being thick/strong enough you can clamp it in a vice and attach a rope to the forktips where you bands would go, if you pull and it breaks, well it wasn't strong enough. but this method can destroy your slingshot too so if you don't want to break it i wouldn't do this and just keep it as a look-at

    Hello Howard, <br>I can' t say it better than onnod,... only... instead of" keep it as a look-at" , just put some soft bands on it and enjoy <img src="http://illiweb.com/fa/i/smiles/icon_cheers.png" alt="cheers" longdesc="28">

    Would 6mm plexiglass sandwiched by 3mm multiplex work as fork material? I have several pieces of it just laying around my shop. Might as well use it, if possible.
     
  9. FlipGun and I were tinkering around with "Pop Shots", making slingshots out of pull tabs from cans (soda, beer, cat food, etc) and those little things aren't as strong as plexiglass. Just don't put too strong bands on the shooter and it should be fine.

    Just a thought. I could laminate 2 pieces of the 1/4" plexy together. What do ya think? Stronger or would I still need the multiplex backing?
     
  11. Doubling the plexy would certainly make it stronger, only way to find out how strong it is will be to test it. Could put progressivly stronger bands on it to see what it can handle.

    I'll give it a shot. No pun intended!
     
  13. I am interested in the results, plexy is so cheap and comes in a massive range of colors from of course clear to a black so deep you cannot see through it, so if it can hold up to some target bands I will be most excited.

    It may be awhile. I have to dig my saws, sander and the rest of my tools. Hurricane Sandy dropped a ton of snow on us here in WV so I closed up my shop that's in my unheated garage.
     
  15. Understandable, I wouldn't want to work plexy with nothing but hand tools either.

    i already saw a plexiglass one in this forum at the very begining that i joined.<br>if i remember, it was one of hrawk...? i remember that it was a beauty with a sky background.<br>for that kind of material you got to know the polishing process and have the good machines imo.
     
  17. Yes, to work with plastics (especially ones with a high abilty to polish like plexy) you need pretty good tools. Low speed sanders and saws simply will not work worth a darn.
