Re: Slip Tip accuracy testing video
With a good tip ( put on corectly ) the acuracy differance is negligible . At hunting ranges the if the slip tip is making you miss you aren't doing it right .Here is a pic of a necked down shaft , 5/16 shaft gets a 9/32" tip , 11/32" and 3/8" shafts get a 5/16" tip , it's a very streamlined set up and it solves the slide ring jam problem at the same time

Re: Slip Tip accuracy testing video
I have always said that these slip-tips on the market,even the best ones spoil the accuracy and you cant rely on precise shots,it becomes gambling.I noticed that even the angle of the small barbs has effect,especially if the barb is only one.But the slide ring is worse.
Im working on a new concept,wich many people would say that is not tought enough,but its working good for me and gives relieble shots) |

Re: Slip Tip accuracy testing video
@Spearo Tastic I think you should realize that I have been trying out different configurations with slip tips, and of course I have tried every spectra line setting there is. As mentioned in the beginning of my post the normal way of setting up slip tips (as shown in the video posted) or by simply pulling the spectra inside bands already pulled ... didn't test well at all. In some cases the shots were missing completely the giant big target! My guess is that if not enough tension is put on the slip tip, once you shoot, it will get stuck in a certain orientation and that could be crooked. The way I do it puts a lot of tension on the slip tip and keeps it set, then when you fire the acceleration of the shaft takes over and the slip tip stays put. This made a dramatic difference in accuracy, especially in the "looser" slip tips. If your shaft overhang is less and you have a very long line sticking out, you can shape the line in an S shape and then put it under the band before pulling the second one over. On some guns like RA or C4 you can't do that as the bands are separated, but have a few other solutions for that too. Give it a try, you will not be disappointed. In the meantime I am lucky enough to have 2 of the Mori custom shafts and I setup the second one with a longer spectra line and tested at 5 meters and 6 meters. Here is the video
https://youtu.be/JDcaW1q66ms @Phil I don't know why you had the scale problem with your tip, but I have had these 2 shafts for almost about 8 years and never ever did I have that problem. They work like an absolute dream and I always loved them most due to the fact that they deploy so well. The tube is tucked in the shaft and has a much slimmer profile than a slide ring so if anything, it would have much less chance of getting stuff stuck in it than a slide ring. The only problem I have with them is that the shaft metal is a little soft and if I overpower the shaft I lose accuracy, and also they are only 7.2mm thick ... for long distance shooting I like a shaft with at least 8mm thickness. I do have slip tips similar to the one you have in the picture like this one from Hunt, but in testing the slide ring destroyed accuracy and having the big bulk of the slide ring so far up the shaft has its downside as it creates a very large bulky shape that hurts good penetration on fish. As for the spectra line getting stuck ... well that depends on how thick your spectra line is and how big your slide ring hole is. On 3mm you can splice 750lb spectra all the way through and knot it at the end and the spectra will never get close to jamming. On 2.5mm tube or thicker spectra the best way is to use a Brummel lock splice where it just barely exits the end of the slide ring (this gives some tension to hold the slip tip but still easily toggles) and then do another normal splice right after the end of the line behind the slide ring and then knot it. This gives you double knot strength where it is needed and still keeps the slide ring free. As for the slip tips not fitting on different Mori tips. Even the Mori tips I have that came with screw in tips fit perfectly on my custom shafts ... no problems there at all. @Jolinedaniel Thanks and yes q8 is Kuwait @Red Tide Yes the magnet idea is a great idea and have tried it. You place a small magnet inside the spectra before second knot after slide ring. I have ordered a few different size magnets from Amazon to give this more of a go. The magnets do have a problem of rusting and they tend to work themselves out if they are too small. It is a solution that needs a little more work but another way am working on is to simply tie a tough O ring at the end of your spectra line and then have a tiny "knob" on the shaft where you pull the O ring and hold it on the shaft. This would be great for RA and C4 guns where you can't pull line in the bands. @Seal Yes you are right the slide ring is the biggest problem and it destroys accuracy and robs shaft velocity and hurts penetration on fish. Initially I was prepared to not only weld a tube but to even route a groove for the spectra line. I realize now that is not necessary and what needs to be changed on the shaft is to simply weld a small tube and have it a little recessed and just get ride of the slide ring. Having a slip tip head shaped on the shaft is of course nice, but screw in heads will work just as good so long you get rid of the slide ring. Can you share what idea you have used to get your slip tips to shoot well? Anyway if you have a slip tip setup that works well for your hunting then great and no need to change anything. But if you have had good trigger pulls and were shocked to see your slip tipped shaft miss and blamed it on your poor shooting skills ... well don't be harsh on yourself. I think it is also harsh to call Riffe Ice Pick slip tips or other slip tips as garbage as they are simply not designed for accuracy. A fish shot with an Ice Pick will hold the damned fish just as good or better than any slip tip out there, just need to get to point blank range before you shoot. By the way here is a picture of all the different slip tips I tried and a few more are not even in the picture ... trust me was pretty comprehensive. |

The accuracy issues that everybody is concerned with are true but the fish I am hunting with slip tips are usually large and pinpoint accuracy is not a big deal. I am a methodical hunter and have conditioned myself to not take shots that are more than 15 to 16 feet away. My goal is good penetration and let the slip-up do it's thing.

Re: Slip Tip accuracy testing video
^^^^what GR said about discipline and getting in range for the best placed shot on fish.
Sure you can always build a better mousetrap.....but in the end it's better to be a lion than house cat with a bag of technology to land the fish. Test your setup and learn the deviation and account for it.

Re: Slip Tip accuracy testing video
The turned down collars on shafts is nice for keeping the slide ring in place. I have done this on my shafts in the past. I do believe it may cause some penetration issues in some shots but it is just a feeling. I no longer use the turned down collars because over the years those shafts have been damaged in one way or another and I do not miss them enough to bother doing it again.
One last comment is that there does seem to be a more noticeable affect on smaller diameter shafts. My 72 inch 3/8 shafts powered by 6 bands goes right where I point it. I have never missed a shot with that gun. My 72 inch 5/16 shaft with 4 bands is very good too and I may have missed a few shots over the years but that is a rarity. My 72 inch 9/32 shaft with 3 bands was very inaccurate and I would not recommend that combination for a sliptip gun set up. All of these guns are enclosed track mid handle guns. The lighter shafts seem to be affected more with the drag at the tip than the heavier shafts. No science just experience.

GR can you post a picture of your set up. How big a magnet do you need.

Re: Slip Tip accuracy testing video
What do you think about welding the little tube directly to the slip tip base

Re: Slip Tip accuracy testing video
Well, last 2 days I decided to modify a few crappy shafts I have from Salvimar with very obtrusive floppers and wired shark fins that wishbones always slip on. I cut off the tip just below the flopper and then threaded the tip. I had a couple of Salvimar slip tips that were very streamlined but had cable. This slip tip is a little different as you have to heat the tip to melt the glue, then replace the cable. Instead, I cleaned out the inside and dulled and polished all the sharp edges, and managed to fit 1000lb spectra in there. I then sanded the inside of the tip to get some grip and used my golf club epoxy (has tiny glass beads) to set a chemical bond to the tip. Not sure how strong this will be but the epoxy is not holding any load, but am worried that the 90 degree angle might wear out the spectra quicker. For the shaft, I had ordered from onlinemetals.com a few tubes @.1875" x .049" x .0895" and a couple @.1875" x .035" x .1175" ... a 12" tube will probably be enough for 2 dozen shafts. I ended up using the tube with the larger diameter hole so that I could fit spliced 750lb spectra with no problems. I then routed a small groove to put my tube in and had it TIG welded. Of course spent some time polishing all sharp edges so that the spectra wouldn't get frayed. I also had some shark fins that I had laser cut some time back and got rid of the terrible wire fins that came with the Salvimar shaft and replaced them. I had 2 different types of shark fins and tried both. The shaft metal was actually quite good 17-4ph hardened SS so I think the end result was great, and it was an 8mm shaft so was very happy with that! Took it out in the pool and accuracy was just like the Mori custom slip tip shaft! The only difference was that the power was massively increased penetration wise. I always realized that adding mass to the shaft gives a lot more power, but I had expected that with the same bands the shaft would be slow. Instead it penetrated all the way through the target and I could have sworn the velocity was much higher than 7mm shaft. It is possible that my bands are overpowered for 7mm and that extra power is getting good use with the heavier shaft. On my last test shot the shaft pulled so hard it pulled out of the crimp. I had rushed the line rigging and forgot to crimp the crimp. Accuracy wise I now have absolutely no doubt that this is the way to go with slip tips.
Here are some pix of the work I did. Really nothing hi tech here ... just mill a small groove on your existing threaded shaft making careful that it is absolutely perfectly oriented with your shark fins, and put a small tube and get it TIG welded. Make sure all sharp edges are dulled and buffed and you voila! you have a super accurate slip tip. So far have only tested with pencil slip tips, but have made a few more shafts with different threads that will allow me to test all the slip tips I have already tried out previously. I think this will make all slip tips more accurate, but some that are not streamlined and might still vector the shaft off line. I am travelling tomorrow to the Red Sea and of course will take this new home made shaft to give it a try there. Dogtooth are supposed to be running there and this will be a good test.
