Measure how hard you are pulling

Has anyone ever felt the need to measure how hard the pull of your bands is?

What I'm asking is, should I get this? Or waste of money?

No, I don't have any other pull measuring device at the moment. And using bathroom scales would be dumb and desperate. I am not that desperate.

Thanks all.

My motivation was simple curiosity. I like things reduced to numbers. It's an Asian thing. :rofl:

It's like these archery people say, "I shoot a 60 pound longbow!"... I wanted to say, "Frak you Guy... I shoot a XXXpound slingshot" and throw the JEPG evidence in his face....

But Asians are also penny pinching buggers... so the money has been redirected to a diamond sharpening stone. Never used a diamond blade sharpening stone... now I'll get one. Will no doubt prove far more useful to me.

Thanks again for helping me decide.

I love my diamond sharpening stones and to be honest they see a lot more use than my slingshot draw weight gauge :) I like to pair my diamond stones with a home made strop just for good measure. :)

Just for the sake of conversation I could see measuring flats and what it would take to equal that in tubes. Also the same length in tubes or flats from one batch to another. I guess if you were a real serious numbers person, you could chart how much loss of power after so many shots. We are all different, so if the technical side of shooting is what you like, go for it.

A friend of mine ran a bicycle shop for several years, and though he loved his job he said never work at the same place as your hobby.

One mystery that I was trying to solve was the difference between Chinese tube rubber and Pakistani tube rubber. The Pakistani rubber stretches to the moon if you let it, even though it's got a more solid cross-section than the Chinese tubes. It only develops some power if you shoot full butterfly which I dislike doing. I'll probably need to make loop bands out of it or something. But it's not all that important.

Anyway....

Make a loop of paracord around the handle of a bucket and through your bands and fill the bucket with water. Center the paracord in your pouch and lift the bucket with your slingshot, add or pour out water until the bucket lifts off the ground when your bands are stretched to your draw length and weigh the bucket. You can use free weights for working out too but that method isn't quite as exact

Yep. That'll work.

Thanks, man.

Which makes me think.... I can also stand on my bathroom scales and pull on the bands, fixed to the ground, to my draw length and note the weight increase...

While I always come back to "feel" and something comfortable, or that just "feels" right, I am also a numbers curious guy. If you search Amazon for "luggage scale" you will find many options for not much money- many under $20. Stand on the frame and pull up next to a yardstick for a rough measure, put the frame in a vice and pull along a yard stick on the bench to be more precise...

For me, I am amazed at how fast some of the 12-15 lb draw weight bands will spit out smaller ammo while being very comfortable to draw, and how well some of the 20 lb and under bands (still in my range) can do for me with heavier 7/16 and 1/2 steel. Also, when trying some things that others describe, I see how they get the really high velocities and then realize that it is a pretty heavy draw when it pulls 30+ lbs on the scale (which is out of my comfort range).

The scale and a chrony have given me a lot of entertaining time putting numbers to things that feel good for me, and giving some basis for comparison with others along the way. Now if I could just find a reliable chronograph that was as inexpensive as some of the luggage scales off of Amazon.....

I'm going to make a couple more movies for YouTube pretty quick, a few on the slingshots and a couple on the blasting we do in our gold mine. I picked up a cheap luggage scale for $6.00 for the slingshot movies as I compare different bands and brands, singles, doubles, tubes and then I'm going to see if our archery shop is still open and use his chronograph for the different speeds.
I mean for $6 bucks, it didn't break the bank, you know. I'm a numbers cruncher also.

When it comes to sharpening knives, it's hard to beat a belt sander.
I had been too deep in the woods for too long when I made this old video, but razor sharp is what you end up with after honing it with a leather belt on the sander.

I said I ordered 2 diamond knife sharpening plates and a diamond knife sharpening pen instead of the measuring scales. Well at least the pen arrived 2 days ago... took 2 weeks to get to me from China... WHY??? China is right next door! Put my poo on a freaking truck and drive it across the border, man.... don't know why it takes 2-3 weeks...

Anyway... it does what it sez it does. I'm happy. Only thing I got that will sharpen a karambit (yes I know you can wrap sandpaper around a pencil..)

Why don't you just use a diamond stone? Just curious. I know many people that can sharped a karambit on a stone. After the stone give it a dress up on the sharpening steel then strop it.

I did order that (see above in thread). The pen got here first. The plates will probably take another week.

You can. I use the edge of a stone. But a round shape works better. If I got a choice, might as well use it...

BTW the pen really shines when you need to work on a serrated blade. Like my knife here:
