i made my first tube set last week out of 1842. this week i finally get around to make a set out of the 1745 i got from truly texas. i put the tubes side by side and i cannot tell the difference . they look exactly the same size and are both black. od and id look the same. did someone ship me the wrong thing?

It's possible, but eyeballing the difference between 1745 and 1842 takes a pretty well calibrated eyeball, there being only .1 mm difference in inside diameter and .3 mm in outside. If the band lengths are the same and pull weight is the same, then you probably did get one shipment mislabeled.

Take a look at THIS thread which shows the difference.

thanks...i have downloaded those charts. Henry is right...too close to eyeball. the 1745 is drawing a bit harder...i have to make sure i keep the labels with the tubes.lol
i'm thinking 2040 in yellow for target practice and 1745 for hunting which i don't expect to do unless i have to. everything is illegal in connecticut. grrr
i wish i had not got a multiplex ss off ebay with theraband gold.( under $8) it's my favorite and now my life is more complicated. lol

Hi Douglas, seems strange seeing you in this part of the world. There is a difference in the two sizes, not much visually. The OD of 1842 mics about .160” and 1742 .185”. I say about because I find variations even within the same rubber not to mention variation in different lots, and it is difficult to measure a compressible material precisely. I also think that vendors sometimes get mixed up themselves and send the wrong rubber. I say this because I was trying to keep my inventory balanced and used about the equal amount of both 1745 and 1845 in early testing and ordered each type alternately a bag at a time. At present I should have two unused bags of each, while in fact I have 1 bag of 1842 and 3 of 1745. I am more familiar with the rubber now and picked it up visually. Also supporting this theory I saw a recent post of someone supposedly received 2040 from China but the new rubber did not match the old 2040 but closely matched another existing rubber the man had on hand in both general size and draw weight.

hay pgandy...always a pleasure the hear from "the most interesting man on the planet"(not that beer guy)...
i have maxed out on blowguns and blowgun equipment. i had to get a variety of stuff the find out what works for me and what i enjoy the most. now it's just practice...
i did the same with slingshots. flats,tubes,dankungs and multiplex. so far my two cheepest ss are my favorites. i now have to start to figure out ammo. i've been shooting trumark plastic practice ammo in the house. i'll hunt if i have to so i think i'd better start practicing with some hunting ammo. i'm not sure what that should be...maybe 3/8 steel? i'm liking 2040 for in the house and i have 1842 and 1745..i think either would do the job on some dinner.
you were right about the tubes i have ...they look the same but i can feel the difference as soon as i take one shot. big difference. i just gotta keep the labels from getting mixed up . lol
i'm joining another forum but under an alias. after posting the opsec questions people who really cover their tracks contacted me privately. their expertise ,military and civilian, has been a real eye opener. i was shocked to find out just how much of my business is on the net for anyone to find. i'm not doing anything i need to hide and i'm not gonna flag to the government but info on me should come from me.
well friend, gotta think about getting ready to stay up all night at work. poor me, online all night and reading books. lol

This is the reason I have only been using (and offering) 2040 and 1842. I didn't notice any significant difference in 1745 vs 1842, but I liked the performance of 1842 better. Maybe the 1745 would be better for larger diameter ammo (bigger than 7/16" or 1/2"), but not too many tube shooters use that size.

I agree with you comlpetely. 1745 pulls harder and seems appropriate for heavier ammo. I think 2040 will at least for me prove to be best for target and 1842 or 1745 for hunting which can only happen in a "situation". Nothing is legal in Connecticut. I don,t have any 2040 and may have to order it from Dankung but pouches i would like to get from Percision Catapults. I can,t find a link to do that ? BTW...i,m saving up for one of thofe african ebory ss. Looks like the ultimate. Sa...weet.

So, if 1/2 is the size ammo for 1745 then what is generally the right size for 1842 ? And 2040 ?
I guess most band shooters are using steel for target and hunting. Simple to use one size ball. I,ve been shooting trumark plastic practice balls in the house.they are pretty light.
Thanks for input.

In my opinion, 3/8", 7/16" and 1/2" work well with 1842. I have shyed away from 1/2", and mainly shoot 3/8" and 7/16". 3/8" and 5/16" are great with 2040. However, MJ really likes 7/16" with 2040. I don't like that combo myself, but that's just me.

True 'dat!
This is my go-to combo for target shooting. Easy draw and I prefer the size of 7/16" for better grip in the pouch.
I like 1842s and 1/2" for pretty much any other kind of shooting because of the power and longevity. I'm about to go on "Grackle Patrol" to get them out of the garden and 1842s with 1/2" will do very well for that, I think.

[druglas]

I,m just trying to avoid buying one of each like i did with ss and bg. Now i,m gonna have to give away the units i don,t care for like the ergo multiplex with universal forks.

[druglas]

So...if you were gonna buy one size for both target and hunting using 2040,1842,and1745 it would be...7/16 ??

[M_J]

1842

[Performance Catapults]

3/8" with 1842 GT and Comp, generates enough kinetic energy to harvest small game, with a head shot.

[pgandy]

If I were to buy one size I’d go with the 1842. The 1842 band set I like most is one loop cut 13.75”. After tying they are about 6½” from the forks. Originally I cut them 1” shorter. I couldn’t tell much difference in performance without the chrony and since the bands generally break at the pouch I get on more tie per set after breaking with the extra length. I estimate just over 1000 shots per 13.75” cut. It doesn’t take much effort to pull, and ½” steel gives about 7½ fpe and lead a little more than a fpe more. You should be able to up this by using a pseudo taper. Band life may go down. Recently I’ve been shooting 1745 more as it pulls harder giving me PT to use 2040 band sets. I am getting about 10.3 fpe with the 1745 and 12.0 with 2040 which is pulling 19.5#. I am using the 2040 with a double loop of pseudo tapered band.
