Very interesting. How did it workout.?

 

Patent pending?

 

Reddirt could send it to me I could test it and let everyone know how it works and how my patent is going

Great idea

 

I would use a plumline as a reference for the laser. That would make it easier to align them and increase the precision.

 

I built a prototype tool for setting center shot.
It has a laser light you screw into an arrow and one you screw into the stabilizer hole. You put the bow in a vise and project the light on the wall. Then align the dots vertically.

Sorry to rain on your parade, but every method to find center shot has failed. Stabilizer bushings have found to be not straight. The EZ Eyer Laser was thought the cat's meow unitl proven to wasn't. The only true way to find center shot is through shooting. I can eyeball center well enough to get me in the ballpark. At the shop we use to eyeball center shot all the time. Out EZ EYE Laser gathered dust and eventually we got it sold - i offered over dozen new batteries to go with it.

nuts&bolts "trick" does pretty good when other methods seem to fail. Arrow rubber banded to the rise. Move rest so nocked arrow is parallel to the arrow on the riser.

Been using one of these for over 30 years, aways starts me off on the right foot.

 

I hope it suits your needs, but my concern would be that anytime something as "precise" as a laser is screwed in/unscrewed you introduce a tolerance variance; suppose your light emitter isn't absolutely square, or gets bumped out of alignment, you could be adjusting to a bad set of standards.

Plus, it isn't BlindArcher friendly

My center shot is much more crude, but then so is my arching skills... I have a wire about the same gauge as a coat hanger with a 90deg ish bend in it and a small bracket on the long end. I lay the bracket on the riser where the sight would mount, flip it one way to set the marker on the short leg in line with the string, then flip it and align the arrow up with the marker; essentially the tool compares the distance into the window of the string and the arrow from a fixed point on the outside of the riser. Not "laser" consistent, but even small bends in the wire don't effect the end result to a noticeable degree as long as the tool isn't bent while in use measuring a specific riser/time. Plus my center shot tool adjusts for tapered or barreled shafts, where actual center shot alignment changes as the arrow is drawn.

But still, a cool idea.

 

Have to agree wirh Sonny.screwing into a stablizer mount is not going to be even close to being accurate.
Screw a long stabilizer into the bow then see if your arrow will line up with it. The vast majority of the time it won't.

 

I had something similar once, as you screwed it into the stab it left a big egg-shaped circle on the wall

 

No plan to patent. Others have noted valid issues.

Very cool idea but as many experts have pointed out, it’s more complicated than many believe. Perhaps a modification of your Idea could incorporate Nuts n Bolts technique using arrow laser twice and measuring gaps between arrows and light on a distant surface.. Even then, Center shot is not a fixed point for even identical bows because of the countless variables each shooter introduces into the tuning of a bow.

 

Just eyeball it, it's a starting point for tuning. Centershot is not a set-in concrete can't move it position. Same as nock position.

 

Fun idea. Have fun playing with it.
As others have said not really marketing worthy. However there are some people that can sell ice to an Eskimo. Or gasoline thats on fire.

Lots of times people have a measurement in mind. They set arrow to it then tune the bow. Some never touch rest again others do.... It's all personal preference.

Again have fun and let us know how it goes for you.

 

It would be better to use this at full draw in a draw board than in a vise at rest/brace. Still, there are way too many variables that make it not worth using imo.

Still a good idea...

 

A simple block with Vee groove cut parallel to the edge at 13/16" to place against the inside of the riser would be more accurate.

 

Cool idea, but i feel it's over-engineered for its purpose. It's easy enough to measure the distance from the riser or set an arrow against the riser to check if they are parallel.

Much like the Bowtech cam lean lasers, it may work, but a long straight edge works just as well.

 

Cool idea. Remember, on most bows things change at full draw.

Ahhhhh

 

Ha - I remember that. Do people still use these?

 

I like it - seems like it will definitely get you close enough to start tinkering.

 

sonny mentioned Nutz&bolts method which I have used, but thinking along OPs line of thought you could put the laser on both arrows and then use the dots on the wall to adjust the arrows instead of a paper gauge.
That might make it a little easier to align.
However, as much as I like nutz&bolts method, I still end up moving things when tuning so the ol' eyeball seems to be the quickest to get me in the ball park anyway.

To add to the use of the laser mount on the end of the arrow though. I have used them very successfully as a grip/form training tool. Mount on arrow and draw, align peep and scope/pin to target and note position of laser dot vs pin on target dot.
Let down and repeat.
If your form or grip (especially grip) changes or torques the laser dot will show that difference in position in real time and allow you to adjust and "feel" what your normal grip is.
If everything thing is consistent then the laser dot should be in the same spot every time.
This take out the variable of release action and follow through so it can help narrow down causes of misses.
You don't even need to be at the range because you never fire the arrow, just be safe though!
Thinking of this, I should do some more drills on this soon, it's been awhile.

 

All i look for is my whale tail looking good on the shelf. I leave a little room so if i go down with my rest the whaletail doesnt go underneath and leave a little room so it doesnt start riding into the riser.

 

depending on how much the one for the arrow weighs, I have another use for it. it would only be for, maybe a hand full of people at best. might see if anyone is still using or playing with tunning arrows using the flat line oscillation method.
