    3/8" Cell Cast Acrylic heat formed and laminated and hand profiled then blasted to make that frosty finish. Very strong and light. First attempt.

    I fabricate items from Cell Cast acrylic on a regular basis. I used 3/8". One of the reasons I made the frame this way is to test the strength of the material. I was told to make it at least 3/4" thick but I have a good deal of experience with acrylic and how much load it will bear etc so I made this one to prove a point to myself.

    It crossed my mind. Walmart sells little toy balls that have an LED module in them. I've used them in other toys to make them light up when struck or shaken.

    I appreciate the feedback. I am going to tweak the design but keep the elements that make it so unusual. I've got an idea on how to make this an over the top shooter. I also want to simplify the band attachment...the grooves and holes are a lot of time spent with more time to spend tying and retying bands. I've got an idea for a pinch that will trap the band material without resorting to a screw down clamp.

    Good job! I like plastic shooters, pvc is also easy to form and makes a strong SS.
    Keep us posted.

    That's nice frame. I'm not familiar with cell casting, sounds like an interesting process for making slingshots. It would also be interesting to see you use this process to make some of the favorite styles from around this board. I would wonder if this plastic could hold up to a design like Joerg's Moorhammer, for example. I'll look forward to more posts about this method.

    Thanks for the info. I'm using this material because I have stacks of it from other work.

    There are two types of acrylic sheet: extruded and cast. Extruded is like the stuff you get from the hardware store...terrible to cut, gummy, melty, brittle, prone to crazing and stress cracks difficult to polish not optically perfect not terribly strong. Cast Acrylic is called Cell Cast because each sheet or rod or tube is cast in its own mold but all the molds are usually connected...i.e. cells. It's far more expensive than extruded but it is optically perfect and clear and a whole different animal to machine and cut and polish with good strength.

    Just made a nice over the top pistol grip from acrylic today and followed that up with a Rosewood PFS. Thanks for your interest and kind words.
