Just make one, they are simple to make and work as will as a bought one.  Save your dough and use the savings for something else.

It is much easier to make good wood arrows with a decent tester. I bought the Spine-o-meter several years ago.
It is a great tool and essential to making good arrows. Nothing wrong with a home made rig-used one of those for years too.

I bought Bearpaws Electronic Spine Tester, and is highly satisfied.

Easy to use and it gives me the possibility to short out the cedars to same weight.

It is a tool that serves you well when you are making your own arrows.

Whump Sez; well this is the scoop--wood shafting of any kind will have a weak and a stiff side. I shot wood for years and I  always set my cock feather to the stiff side to try and maintain some form of consistency, [after I built a spine tester.] The closer the grain of the wood the less problems I had with stiff,weak orientation, but the longer grain woods showed enough difference that it sometimes required turning the cock feather to the inside to make a shooter out of a wild flying arrow. After I made and started using a spine tester it took a lot of guess work out of arrow building. I always hated having to mark arrows for cock feather in or out [ before the tester ] and it just added to the confusion in a hunting situation. If you are building arrows now free of confusion then I wouldn't mess with it, but it is a good tool to take head slapping out of arrow building.  Hunt Safe.

Well, I have managed to make it through 50 years of archery without one and do not consider them a "must have" item.  I know if I had one I would become obsessed with the spine issue and I have absolutely no problem getting good flying wood arrows.  Same with the chronograph--lots of people are quite happy with their bow's speed until they shoot through one and get a number in their head that they start to obsess about.  Archers did well for thousands of years without all that stuff.  Just me, but I try to keep this thing as simple as possible.

You can make a simple and fairly accurate spine tester in about 10 minutes and calibrate it with aluminums.



Make one of the arrow supports fixed and one like a cam so you can adjust the arrow to the "zero" line.  Find a weight you can hang from a binder clip, put in the first aluminum and mark where the bend in.  Repeat until you have everything you need.  There's a chart floating around what the aluminums spine out at.

Simple and accurate to within a # or two.

I guess you were looking to get talked into it - if you are just flinging arrows you don't really need one. It helps a great deal if you want better and more consistancy in your shafts. Life was more simple buying 1-2 dozen at a time - with the spine tester it will MAKE you duy 100 at a time, sort through them and have several terrific groups which shoot the same. Make sure your going to stick with wood shafts before buying it. They are great products.

I make one with a dial indicator and its really easy to do.Wish I used photo bucket I'd show you how. However you can build one for less than $35 thats as good or better than any of them. Frank

Ok,

B/W lvr that is just a straight up tease! :-)  To load your pictures go to Imagelinky.com use the browse buttong to select your pictures. upload then by hitting the upload button.  Go to the third line under the picture.  Copy the entire thing and paste it in your thread.  Simple as eating pie to load your pics.  If you have questions send me a pm.

I made the same exact one as Reddoge for 25 cents. The cost of a photocopy to enlarge the dial printout. Plans for free on the internet. Materials found around garage. 2lb lead weight(old lead shot and wheel weights) in a soup can with a wire hook. Weighed at post office to be sure of weight. Spine chart free on internet - Rose City Arrows.

Works awesome! Dead on accurate!

Thanks for all the replies ! Now to study them and decide which one to make ! I didn't think I would be building one, but it is defiantly a money saver.
Thanks again.

Dan when you get it all figured out Can I borrow it...LOL

LOL

I thought bare shaft testing replaced spine testing?

Dan D,

I have a spine tester that I am not using and would sell it to you if u r interested.

I have plans to make one one day but I've been kinda lazy in my own home projects with all the other stuff I've got going on & with 2 lil ones my own stuff gets harder & harder to do.

Just make your own.  Get a board and add a couple dowels 26" apart.  Get a 2# weight.  Find some arrows that shoot well out of your bow and spine test them.  Mark the spot on the board.  Then you'll know.  All that deflection, dial indicator hocus pocus just confuses me.

Hmmmmmm.......  I was going to make one, but then I realized after buying the indicator and other odds and ends I might as well put the money towards just buying one. Your method would be very reasonable, good posts guys, don't know if your making my decision any easier LOL, I'm leaning towards buying one, but it is early in this post yet, I'm going to sit back and read your thoughts on this, Thanks !

Dan, I made my own in about 4hrs. one morning in my garage, and made it out of scrap lumber that I had laying around. I'm like you and wanted a spine tester, but didn't want to foot the expense for one, mainly because I'm laid off for quite some time now and money is tight.

You can do this, it's really not that hard. Also, like John said....you just need to know what your spine is for your bow or bows and duplicate that spine. I feel like mine is a "Must Have" item that I wouldn't be without when making my own arrows. It makes about as much sense as a reloader making ammo without a good scale.

Here's the link to the one that I built. It's in PDF format and you can print it out, which I would strongly suggest. The directions read more complicated than it really is. Basically, you are just building a half a wooden box with 2 ends, a notch in the center of the ends to cradle the arrow shaft and a simple pointer to guage your spine. Use what you have around your house or garage and use your imagination. Good Luck!

Here's a couple pics of mine.

You can get yourself a Dial indicator from Harbor Freight for less than $20. and the rest isn't hard to build.

Arrow4Christ,
What is the big differences between the Ace and Spine-O-Meter ? What did you not like about the Ace ? I am needing to get a spine tester too and would like opinions. Thanks !

I like to hoard arrows, got dozens of wood arrows that shoot good and a few that don't. So I build a spine tester and play with the arrows that shoot good. To my amazment the spine ran from 590-740 on like three dozen good arrows. But it is fun to play with on a rainy day...........James
