DIY draw board

[muddyfuzzy]

yes, alot of good points. the primary purpose of the board for me was to verify peek weight as well as let-off. i too have often wondered why no shops around here have them as it is a great tool to see where you are really at. put the bow in spec, tune to peak weight and let-off then measure the draw length. this is an invaluable tool when shooting bows from different manufacturers to verify actual draw length vs. amo published.

sight picture and pin float can be greatly improved by dialing in dl more than the 1/2" that most cams or modules allow. i know what dl i shoot best at and now i can get all all my bows right where i want them to maximize my accuracy.

god didn't create us in 1/2 sizes so i really like the ability to dial it in for me.

A draw board is a nice to have tool, not need to have, for bow tuning IMO. Any good experienced tech can set up any bow properly for the owner. Draw boards help the shooter set up the little things they prefer. Which in a high volume retail outlet, is somewhat a waste of time. And what happens if the draw board is used to help with set up, and the shooter still can't use the bow worth a flip?

Muddy-- can you use your design vertically or is it a horizontal set up only?

there are several examples of vertical designs out there. they look almost identical to the one i made with the exception being they are usually mounted to the edge of a work bench or something. i actually thought about doing that but a have reloading presses that hang over the side of my work bench. the one like 12Ring is talking about with the ryobi miter stand are slick and they can be rigged as a hooter shooter as well.

but the answer to your question is yes, simply mount it that way and you are good to go. i've seen some guys use a bungie or velco to hold the bow on the pipe until it gets loaded then it will right itself.

Well said Rocky. I agree with you 100%. I built a draw board, but like you said, it will be different than waht a person drawing will be because of the hand placement and pressure applied at the grip by the hand vs the steel rod on a draw board.

I don't see how the DL of a bow changes from shooter to draw board.

Call me nuts but when a cam hits a stop its over. Draw length is a fixed length with the only exception that I know of being spongy back walls.

I can't agree with rocky on this one.

I happen to believe its a fundamental tuning tool that every pro shop should have. Just my .02.

Cam stops and cable stops are two different things. Cable stops are when a cam comes around and uses the cable to stop the draw cycle..... you can still pull hard into it and get a different draw length.
Cam stops hit against the limb and stop the draw dead.

I have had a draw board since 07 and use it all the time. BUT for most hunters out there a shop does not have the time to tweak every bow and be as critical as some of us spend on our own. if they did the cost of a tune would go up just in time spent per bow
.
not sure i agree with the draw length changing from drawboard to person.... maybe a perceived draw length due to stiff arm bent arm or some variance. but the drawboard measures from the grip (minus the 1-3/4 AMO)

For the shooter that is not looking to really get into bow setup they would have little use for this. That being said I have one and find it invaluable. I can tear my bow down and make repairs or changes and always come back to my exact settings taken from the draw board. Timing I feel can not be done correctly without one you can come close but not as close as a draw board. It is great to have to use in conjunction with archery software such as archers advantage. As far as measuring draw length I have yet to find a bow out of the box that is exact to manufacturers listing. If you want a box setup bow then eye ball and feel are fine. If you want to get everything where you feel comfortable or get everything possible out of your setup then this will help. If you are going to use a modified setup like I do then this is the way to go. I also do not see how grip changes the actual draw of the bow. If you measure from the burger to the string with the bow touching the draw stop and not into the limbs then you should be fine. Now every bow will change if you pull into the limbs that is given. It will also change if you set your stops to a lower let off, higher let off, use a longer draw mod and shorter strings etc. There is not many shops that have a draw machine but I know that Cinnamon Creek does.

Take a Bowtech Destroyer, put it on your draw-board with an accurate DL arrow, and measure from point of contact with cable-stops on cable.

Now, hand draw the same bow with same DL arrow, and see what you come up with.

I have had this coversation with the guys at Bowtech, and all agree that the bows measure correctly on the draw-board, but are 3/8 to 1/2 inch long hand drawn.

Most shooters currently shoot a low-wrist grip nowdays, putting pressure well below the throat, where the post on a draw-board is.
It should be evident that the bow will act differently.

Rocky, I knew what your reply was going to be with the low wrist or high wrist and the difference in a draw board and someone drawing with a low wrist. Definite difference.

how do the engineers @ bowtech engineer and market their published draw lengths? i assume the use amo, actual + 1.750". if they know their draw lengths actually run out on their consumers then why not drop them down a half size and make them spot on? who wouldn't really be thrilled that a 28" bow is really a 28" bow?

how the bow acts on the shot and using a tool to accurately measure important features such as starting rotation, sync, lean and draw length are two totally different things. i have my theory as to why a lot of draw lengths run out but it is a conspiracy theory and such.

the thread was intended to offer an option to those who might want to give it a shot. i respect your opinion rocky and appreciate your knowledge on the subject; therefore, you are more than welcome to come use my draw board if you ever need one.

Please don't be offended as I think the home tuner needs to use a draw-board in the learning process, and the draw-board will definately help.
Thanks for the offer, but I've had draw-boards in the past.
I'm just an old school tuner.
To some extent, Bowtech has gone mainstream in marketing and manufacturing, to keep up with competition.
If a bow is 1/2 inch long, TECHNICALLY by AMO standards, it is only 1/4 inch long, and most consumers will never knowthe difference.(ask Matthews)
Keep this in mind when you're thinking about what I've posted.....
A draw-board stops immediately when a person stops cranking, but the human muscles are still pulling after the stops.
I think this is a term that Matthews used in earlier literature,(hysteresis).

I still don't follow there rocky. The bow only draws so far. You can draw into a wall, but the drawlength is measured , that's what it is....cable stops may have a slight difference, but it won't with limb stops.

Low wrist, high wrist.....whatever wrist....the bow stops at a predetermined point.....measured from the throat of the grip to the nocking point.

I respect your experience on the subject, but you're going to have to show me evidence to the contrary.

Do your own test, as I have, then let us know whether I'm right or wrong.
As I said, cable-stops are more pronounced than limb-stops.

what kind of scale are you running?
