What works to further silence the TAC 15 crossbow

[scr903]

Thank you guys for all the Input. When I had the kit installed where it would not shoot at all it still made a thud like your talking about. So I don't think this kit will do much more for you than that. I am focusing on grouping now and not too worried about the noise. I will continue to watch this topic and might try again after deer season.

By the way. I did not polish anything. And it did not shoot by itself. I shot it and it did not release. After about 5 seconds it fired. It did this twice. I believe the foam material after I pulled the trigger was slowly squeezing (compressing) until it released the arrow. I just wanted to clear up that it is not fireing in the cocked position. It delay fired after the trigger was pulled. Way dangerous.

Hi Guys,
In an effort to make it as simple as possible to show what I mean about applying the materials the full length of the triggers hammer, I've taken apart my TAC15i and taken a couple of pictures that I hope will show you just how much hammer I've covered with my materials. I strongly believe that it's important to build up all angles on both the upper and lower side of the hammer in order to maintain equal distances on all surfaces.

Again, I'm using a Timney Trigger,but the trigger type shouldn't matter that much as long as the distances to all contact surfaces are kept the same.

I can't do much more than to provide these pictures, since I'm not able to reproduce the failure on my crossbow. If anybody else who is having this problem can show me a case after using this much uniform coverage, I'd be very surprised.

I hope this helps.

Hi Russ,
Thank you for the valuable input about the JPAR Trigger instructions. Every suggestion is very important regardless if it solves the problem or not. If nothing else, it will eliminate another possibility which narrows down the field of which ones are remain.

Between your suggestions and those made by Twanger we may need to wait for somebody else who's willing to work with us on the problem. If scr903 is done making changes, we'll have nothing to test, so we lose the ability to make modifications and validate if they work or not. Speculation without validation is useless, so we need somebody who has the problem before we can continue.

I took my TAC15i apart so I could check tolerances and also take some pictures of how my materials are currently applied. After putting it back together tonight, I'll do some shooting tomorrow just to test and insure nothing has changed when pulling my trigger. I don't expect any problems, but I'd rather not be uncertain, so I'll test again for the record.

Regards,

Jon

Hi All,
I wanted to just take a moment and list the results of some testing I performed with the Silencing Kit Materials as shown in the pictures I added a day or two ago.

I was out back this afternoon doing the testing I spoke about.

It all worked flawlessly.

I shot about 15 arrows at only 30 yards. I was shooting a 1" florescent orange dot on my Morell Outdoor Range Bag Target. All fifteen shots fired with no problem of any type and other than some sound produced by the plastic fold open table the crossbow was sitting on, their was almost no sound produced.

There was also no hesitations or misfires of any type. I feel confident that as long as the materials are applied to the entire length of the hammer and over the top and down the back side of the hammer, a uniform thickness is being applied to all surfaces that come in contact with any parts on the cable sled, so there should be no problems, if owners would just follow these directions we've created, they should not experience any issues. I'm only speaking for the Timney Triggers, because I can't speak for others that I can't see or test.

I have some additional shooting to do, since I'm doing some comparison testing between my precision matched custom PSE TAC15 Arrows in 4 Fletch configurations versus a custom matched and tuned set of Aerobolt II's in a three vane configuration using the latest Aerovanes. These tests will be performed at 90 meters providing I can get a very calm day with no wind.

This will also allow me to continue shooting more shots through the Trigger Silencing Materials, so I'll add to this thread once I finish my other testing, but for now my official position on the effective fix for the Silencing Kit is exactly as shown in the pictures supplied in this thread.

Regards,

Jon;
If I wanted to try to install the kit like in your pics. where could i find the material. It looks like they took the kit off the site. By the way the kit does not come with enough material to do the install like you recomend. It only had a few small pieces with it.

Hi scr903,
Please send me and e-mail to jon.henry755@yahoo.com, so I have your outside e-mail address and I'll be able to respond to this request.

I can't publish in an open forum the information where different materials come from, since it may affect somebody else's means of making living.

Obviously, I didn't purchase my materials in a kit form, so my use of materials is not restricted to a certain size limitation.

Regards,

Jon Henry
