I just bought the new overdraw bracket offered by Hamskea for their Versa rest. I was a bit skeptible at if it would make much of a difference. I decided that respected archers like Tim Gillingham, Jesse Broadwater, Randy Ulmer and a handful of other top archers must use an over draw for a reason.

When I saw that Hamskea offered this new bracket I decided to give it a go. I installed the bracket and shot at 20 yards. And essentially "torque tuned" my bow. I purposely torqued the bow from side to side and was very pleased to see that the arrows all hit together despite the torque. Instead of horizontally missing.

Pretty cool!! I didn't cut my arrows down although you could because the rest is further back now. I wanted to keep my same arrow length and weight. Shooting a 2012 Carbon Matrix. Hamskea Versa Rest.

As a bowhunter I am always looking to better my setup. To find things that help with forgiveness and in turn produce more accuracy and more success. This is just one more tool.
























Here is an article written by Tim Gillingham on the subject.

"Understanding Torque Tuning
​​​​By: Tim “the Hammer” Gillingham

Over the course of your archery experience you may have come in contact with many opinions on many subjects and you will probably have various reactions to them. Most people take things repeated over and over again as the gospel and it seems the more it gets repeated the more it gets entrenched into our psyche.
You may have heard “ Overdraws make the bow more critical!” I tend to disagree and let me explain myself.
First I must give credit to the person that first brought the topic up in the first place. Many know world renowned professional archer Jesse Broadwater. Arguably one of the best archers the world has ever seen and probably the very best in the world today. He showed up on the scene a few years ago shooting an overdraw and many wanted to know why. Now I personally had been shooting an overdraw for many years for other reasons like being able to cut my arrow shafts shorter to lighten them up and make them stiffer. I had never seen a loss in accuracy so I continued to shoot my setups very successfully with about a 2” overdraw. When Jesse started talking about what he was doing I decided it was time to run my own tests and really try and figure out if indeed an overdraw was more forgiving.
People were talking about “Torque Tuning” their bows and a friend of mine was convinced that the perfect spot on my particular bow for the rest was ¾” from the throat of the grip. After much testing an analysis, this is what I found and it was not what he had thought. The perfect spot for my rest was right where I had it with a 2” overdraw.
Problem:Two things happen when we torque the bow, we are moving the sight one way and the arrow the opposite. The reason we get an impact change due to torque is that we are making compensations with the sight when we torque the bow and therefore the arrow is going to hit off line
Solution: If we can put the arrow rest in the right position we can find the “sweet spot” where the two actions(moving the sight one way and the arrow the opposite direction) cancel each other out. In laymans terms, this means I can set the rest and sight position to a point that no matter how I torque the bow left or right, as long as the sight is on target the arrow will hit in the middle where I am aiming.
How is this possible? How do I achieve this?
Usually what has to happen in most setups is that the rest has to come back and the sight may have to be moved forward or back to fine tune it. The rest is the primary adjustment because it is close to the nocking point and therefore less of a movement at the rest will make more of a change downrange. Here are the steps:
1. Sight your bow in at 20 yards to start with.
2. Draw the bow with and arrow, torque the riser to the left(arrow getting closer to the cable), put the pin in the middle and fire the shot.
3. Draw the bow with another arrow and torque the bow the opposite direction to the right( arrow getting further away from the cable), put the pin in the middle and fire a shot.
4. If the bow is perfectly torque tuned, all the arrow will hit in a tight group. If not, you will see a lateral spread in the arrows. Typically the arrow you torqued to the left( arrow getting closer to the cable)will impact to the right and the one torqued to the right(arrow getting further away from the cable) will impact to the left.
5. Make adjustments to the rest, usually you have to bring the rest back incorporating the Hamskea Overdaw in conjuction with your Hamskea Versa Rest. You will be amazed at the difference when you start playing with the rest position.
6. Once you get the arrow impacting very close at 20 yards no matter what left or right torque you put on the riser, move back to 50 yards or further and repeat the test. You may have to make fine adjustments.
7. You can also move the sight in or out if that is an available option to you and that will allow some fine tuning also. It has less of an effect than the rest due to its position further away from the nocking point.
Once you get this done you will be amazed at how much better your bow will shoot. One of the other factors that I ran into in this experiment was that the launcher on the arrow rest needed to provide side support. It is one of the major reasons that the Accu-Glide launcher is designed the way it is to provide side support and correction to the arrow on a torqued shot. I found that while testing a skinny carbon shaft on a wide launcher, that no matter what adjustments I made I could not get the torqued shots to come together. A simple bending up of the side of the launcher to provide side support solved the issue and that setup toque tuned exactly the same as other setups out of the same bow with a different arrow.
Where this will benefit you most as an archer or bowhunter is when you place your hand in the bow incorrectly or when you are shooting in the wind and making compensations to keep your sight on target as you are being blow around. In general I think it will make your bow shoot much more forgiving and make you a better archer.
So get yourself a new Hamskea Overdraw and Versa rest combination and supertune your setup in more ways than one.

• The NEW! Hamskea Overdraw will fit your Hamskea Versa rest perfectly and lock to the riser to ensure it will never come loose at the moment of truth. Truly the most durable rest setup on the mark.
• Allows you to shoot lighter arrows
• Shorter arrows mean you can a lot of time drop to a lighter weight and spined shaft
• Shorter arrows mean less wind drift and more FOC for better forgiveness and long range performance
• Lighter arrows mean you can shoot larger diameter shafts for ASA 3-D or faster shaft in bigger diameters for IBO tournaments
• Shorter, stiffer shafts will fly broadheads much more accurately and are much more quieter in the quiver and more portable in the field
I hope this is one more tip that will help you become a better archer and bowhunter!"

What about the wide launcher blade they have with the full capture versa rest? In his little article he said he couldn't get it tuned with a large wide launcher and skinny shaft.
I shot the wide launcher with axis arrows all last season . Do you think this would work with the overdraw?
Id like to pick an overdraw kit up, but do I need to switch to the accu launcher to get it to tune right?
Justin, when you say you "torqued" your bow, how far did you torque it to try this?

Tim mentions for the wide launcher to show the results he had to bend the blades in a bit. I could play around with the wide launcher and let you know what I find out.

I torqued it a good distance.

Justin, What's the longest shots you have taken with the overdraw and how are the arrows grouping? Does the Hamskea overdraw work with other rest like Trophy Taker?

Love your Martix, I have been looking at buying one to try out
Thanks for the input

Justin , I was looking on the Hamskea website and didn't see the overdraw. How much adjustment is there on the overdraw ?

I recently got it on and haven't shot too far. Shot 50 yards yesterday. here was a 50 yard group before I had to go in because my hands were too cold


As far as use with other rests...Im not sure. I couldn't tell you. Sorry

Justin, if you put on the wide blade and play with it, tell me if you get the same results...

How much did the overdraw setup cost ya?

They just released them recently so I don't think they have updated their website yet. Give the fine guys at Hanskea a phone call.

Shrek- there is a few inches of adjustment.



Ok I will play around with the wide at some point.

It cost $64.99 if I remember correctly.

Wow, just when I thought I knew my stuff. I am excited about this idea though. I have a few questions. Does Hamskea offer a pre-bent launcher? How do you go about setting up your center shot and broadhead tuning? It seems like one would possibly wreak havoc on the other. I guess you could get it close and just rely on moving the front sight in and out. I haven't done it yet but this very well could be the last straw where I wrap my bow around a tree. Lastly, will this fit a Spyder Turbo? Obviously I have a ST but I wonder if the guys with the new Carbon Spyder Turbo will have enough clearance, Clarence for their cables.

The accu glide launcher I'm using in the pic, doesn't need to be bent! Works perfect just the way it is. Hamskea offers quite a few different launcher options for different needs.

As far as setup it was easy! I had the versa rest already on this bow. Had it tuned and shooting broadheads and field points together. When I got the bracket I simply put the bracket on and the rest moved back. I didn't have to adjust it any more from there. Essentially the only thing that changed was the rest moved back (centershot did not change, height of rest did not change). The bow shot field points and broadheads together.

I think it would fit on a spyder turbo with no issues. I'm not positive thou as I don't have a ST around to try.
It fits on a Vector turbo and this matrix. So I would guess the spyder turbo too.

Had a pro drop on a freak show bracket on my c matrix for that very reason.Shot great but changed it out for a hamskea on my carbon spider, so I'm glad to hear about this bracket. Shot an overdrawn all through the 80's, but the reason back then was to try and get my PSE to shoot my 2317's over 180fps! Shooting a broadhead was scary as hell!

Different concept, original overdraws was for shorter arrows and to gain speed, this one is apparently for fighting against torque?? We shall see

Maybe where you were. Mel Stanislawski made a bunch of overdaws in his garage and we torque tuned them decades ago. Then he started selling them, along with his roller guard.

Justin thanks for posting this. I fight hardcore to find arrows that fit my 60 lbs at 31 inch draw based off the tuning program we use at the shop. This will help big time so I can shoot shorter arrows and stay within the green. I will give them a call on Monday. This rocks.
