Adjustable ruler for cutting catapult slingshot flat band elastic

Hello, what is the name of this cutting ruler?

What do you think about using a set of calipers to accurately adjust the ruler at each end point?

If you lay 2 sheets of band down and cut both bands at the same time you will have perfect matching pair of bands

I bought mine on Amazon for $8.99
Works perfectly, just cut once and flip it end for end. That's it 👍

Model ?? Ordering info please?

On a fresh piece of rubber with a straight edge is there a way to taper the edge properly?

Do you flip your elastic around each time you cut?

Monkey can use it. Great for some of the lads in catapult community. lol

It maybe the perfect tool for others, but I get anxiety it having to adjust it yourself

what are the dimensions for butterfly shooting and tape thickness thank you friend

Complete explanation , executed perfect example
An Great review. 👍
Now I know what I'm going to get. Thank you

Roller cutter 60mm right?

I suggest you have a 60mm rotary cutter. Anything smaller you will not be able to cut anything with that large edge on the ruler.

Wouldn't that 1st band have a straight edge

If i loosen the nuts up enough for the clear part to slide easily, the bolts fall out or can get lost.

Nice video. I just got into catapults

Hey brother I have just started making my own bands. I got some .62mm orange bands from gzk with my hammer pro. I would like to shoot 8mm ammo. What would you suggest as a starting taper?

Hi, what's the diameter of your rotary blade, 45 or 60mm ? Thanks.

Could you please tell me for what kind of knifes is it? My OLFA 45 mm is not able to cut bands. The edge of the ruler doesn't let the knife to reach the band.

I just ordered this from GZK!

First you need to cut one small piece taper 3mm to 0mm to begin and than to use ruler like you did.
If you don't do that you will have your bands tapered 6 mm from one side instead of 3mm taper from both sides.

Got mine from ebay today. Very handy bit of kit.

i paged through their site under rulers and rotory fabric accessories. cant find that tool. whats it actually called?

I shop on Aliexpress all the time and have seen these but I never really understood what they were for. Thanks to your excellent video instructions I just ordered a couple. To say this is a "must have item" is an understatement. I can't hardly wait to get one and use it. No more measuring and matching up mated pairs. Thank you Sir for sharing, this is some great information.If not for your video I probably would have never bought one. Cutting bands has always been one of my least favorite things to do but that is sure to change soon.

Saw this video and just bought one !

Believe I’ll have a go with one. 👍

Wish I new where to buy one.

I was looking at this on Ali but was put off by the sketchy video. Looks just the job though. Good video 🖒✌
(Phip 😀)

Nice bit of kit hmmm.
