Today I finished a new one that I was eager to make since weeks ago. 5.5 cm (2.16 in) in between forks. I'm still short of a nice, pro finishing but the form and function of this one is OK, very comfortable. Palm swell, thumb support and index pinch offer a strong grip lock. I should name this one: no excuses slingshot.

This looks like a great design and an absolutely magnificent 3D shaping/sculpting job! That being said and as best as I can tell from the pix, this is basically a board cut frame with a palm swell laminated onto one side of it. Because of that, I think all the usual cautions regarding board cut frames apply -- i.e: be VERY careful with shooting this one and inspect it with meticulous care after each and every frame hit (if you ever have any frame hits). Board cuts have a bad reputation for failing while under the stress of full draw and sending broken frame pieces flying back into your face at full speed. The point where the one side of the frame is narrowest because of that angled cut along the outside of the profile may prove to be particularly vulnerable, weak and therefore potentially dangerous if it's ever subjected to a frame hit.

If this design/3D shaping/sculpting job was done with the "split frame" approach that Wombat uses in his frames (see kookaburrakatties.com), you'd have a frame that I'd feel considerably less wary of.

All that preaching being over and done, this is IMO still a great design and 3D shaping/sculpting job. Kudos!

Lacumo:

Thanks for taking the time to check on the design. Truth: there could be a weak point in the design. The wood there is an old seasoned Mahogany. It's strong, but I will be very aware of possible failures in my next one. I may reinforce the thickness of the fork. In fact, I've never had fork hits in more than two years, when I began shooting and making slingshots; a little bit of skill, a great bite of luck, I guess.

Awesome slingshots. Thanks, and thanks everyone to see my baby.

Thanks for the response. I honestly dislike playing the role of "That Tiresome Old Voice Of Safety First" but every now and then I just can't help myself and I have to chime in. When I resumed shooting (as a retiree ~7 years ago and for the first time in >50 years), I had two fork hits on a board cut frame and broke the frame with the second one. Fortunately for me, I was one of the lucky ones. I was wearing safety glasses at the time and I didn't get broken frame pieces flying back into my face at full speed. Thankfully, none of that tiresome cheekbone reconstruction surgery! In retrospect, I think I sub-consciously took that experience as my clue to become The Ranting Board Cut Safety Preacher. Ever since then, I've had a pathological aversion to board cut frames and I just can't stop myself from preaching The Holy Gospel of Board Cut Cautions once every year to two. Also since then... I've never had another fork hit. I learned on the spot how to be DAMMMMMMN careful and I've been paying meticulous attention to stance, grip, aiming, release and follow-through ever since.

Anyhow, some food for thought ... If you did your design using Wobat's split-frame concept (maybe--YIKES!--using some exotic African, Asian or South American hardwoods) or else with 1" thick commercial HDPE board (NOT any DIY HDPE, which can be iffy and potentially dangerous stuff), I think you could produce an impeccable, "above criticism" winner in both the functional and "Beauty Contest" categories. From everything I've read, gluing HDPE to HDPE (for the palm swell) is close to impossible so if you went the HDPE route, you'd probably have to bolt the palm swell onto the main frame. For details on the agonies of going the DIY HDPE route, read https://slingshotforum.com/topic/22723-hdpe-sheet/?hl=hdpeand search "HDPE" in the DIY Slingshots > Slingshot Tutorials forum here. I played extensively with DIY HDPE a few years ago, and all my efforts taught me one thing---if I'm going to make a HDPE frame, I'll use commercial HDPE board, which is pretty much bullet-proof.

At any rate ... good luck with whatever you choose to do or not do from here on out and above all else, be real careful when playing with board cut frames. Thus endeth today's sermon!

Thanks a lot for the kind words. Always encouraging.

Here's a simplified version of thumb support, not so much carving but also effective.

And heres the trick. Remember i work with limited tools.

Next, using the gauge to model the second curve.
