Rather than trim the band to length, you might try using the whole band with a loop at the fork end. This might add a tapered effect and add an extra thickness at a point where you tie to the forks. I was going to rubber cement this extra band area to eliminate friction between the two layers of rubber. I would probably try that type of rubber cement used for bicycle patch...maybe contact cement...not sure yet...Maybe others have tried this to eliminate friction between bands at critical contact points...(?)

As far as price for the 1 pound box of Alliance #107 Sterlings (also the 33`s, 64`s etc.) Staples stores seem to have most beat..... $4.89 each...If you have a store close to you place an order with the clerk and they will ship free to your local store...Free shipping to your home for orders of $75 or more....Shipping for one box to your home wouldn`t be worth it...

JSKEEN....Earlier in the thread I suggested that the extra band be folded over and rubber cemented (like a tire patch)...it should hold, and this would eliminate the need for it to be tied...also, by making the looped end into a solid piece you will be eliminating friction (rubbing between two layers of band)...some experimentation is needed.

For single bands, or those folded over with a short loop, wouldn`t the Alliance #105`s be a more practical choice? When cut they measure 10 inches, and you get 70 {?} to the box...more bang for the same buck spent!

According to Alliance`s specifications Pale Gold Crepe bands have the highest rubber content...about 95%...Though some members do speak poorly of the gold crepe type their have been others that use them...I am not sure, but I think the Sterling brand may be closer to 80% or 85% rubber content...You would have to check with the Alliance website to be sure...

I can understand Natural Forks feeling towards Pale Crepe Gold types, but Bill Hays has recently done a video making comparisons with different types of rubber setups with results worth noting...While using a chain setup with Pale Crepe Golds his results indicate better results than Natural Forks...Perry also uses PCG #107`s on some slings with better results than indicated...Also, in ad promos I`ve seen Sterlings are described as "...Ergonomic...Easy stretch to help avoid Capal Tunnel Syndrome..."

In many cases, the description of a product can be decieving...The seller tries to tell us things about the product we want to hear in order to make a sale...I imagine the only way is to study the available specs and make an accurate test of the product...The forums members seem to have varied opinions on a lot of products used for making slingshots...It might help us all to set up some kind of testing standards...Or possibly use a legitamate test group to sort out the true qualities of a popular product...

I took the advise of geron and placed an order with DYKEMA RUBBER BAND company...They have a 2 pound minimum order requirement @ $6 a pound for #107 with a $5 prioity shipping fee...4 day service and nice bands that are supposed to be 90% natural rubber...The plastic bags are marked a product of Thailand...best of all, no additives in the rubber to soften the action...I don`t have a chrony so I can`t make proper tests, but it seems like a sensible investment...
