Checking bow level...

Hey guys. I have an OMP bow vise as well as the hamskea third axis level. I feel as if the string level portion isn't proper which will throw off my sight axis'. I was wondering how you would go about leveling the bow properly in the vise and then check the hamskea level against that. I have a Mathews V3 31. Can i place a 48" level across the side of the limbs or the riser or? I have a 10, 16 and 48" spirit level i can use. I'm also shooting a spot hogg tommy hogg triple stack. Just wanting to triple check my level before hunting season begins. I was shooting out at 50 yards the other day and feel like my third axis may be a smidge off. It wasn't much but it was enough to notice shot to shot. I never really thought about it until i changed sights. I notice the third axis moreso on the tommy hogg than the axcel i shot previous.

You have your level on your string
You check your riser for level I use a Hamskea for that. Then I put another Hamskea on my site. But a small 8 to 12 inch carpenters level or just a square small level.

I've been using the hamskea for a few years now. I know how to use and setup the level, i'm moreso questioning the accuracy of the hamskea level. I never noticed it much with my other sight and the other bow's i've setup have been with beginners so they don't much notice the difference. But as fat as using a spirit level to check the bow's level, would the riser really be a good place? If the riser has dips or other odd design features i'd think that would lend itself to having level issues.

Only problem with putting a level on your limbs is the fact that your cams may not be both in the same offset from the limbs due to tuning Etc. You really want to level your string to be accurate.

In other words, Your riser and limbs might show level but your string might not.

Has anyone run into a situation with the Hamskea where if you put it on the string one way, it’s level, then flip it around 180 degrees from where it is and it reads different? Also, without moving the bow in the vise, I place the level in a different vertical position on the string and it reads different as well. Am I doing something wrong or is it possible that I got a lemon third axis level and should return it for a replacement?

Post leveler is cheaper and accurate. The longer the area you can level the more accurate you will be. I'm an old brick mason.
A 4ft level matched to the string will work. Or you can put the level onto the top/bottom riser and measure if the string measures the same distance top to bottom. If not add tape layers to one side till they are equal and that will work at that spot.
Any very short level like that will have variance when you turn it another direction. I think it is partly to do with the string twists and how even they are. Putting the hamskea on serving areas will probably be the most accurate.
I'm still planning on buying hamskea but mostly for attaching to and leveling the sight.
But for the string I will continue using this.
When I bought it I went through the stack of them at home Depot and compared each to a 4ft level at the store one a level/plumb shelf post and found the truest one because they are cheap and typically not super accurate.

The thing that drives me crazy is I use the gen 2 as well and the levels from podium archery that goes on the string as well as I think it’s the omp like the cheap ones on amazon with the one that clips on your arrow and they all read something different. They are close but sure not perfect.

I’ve got the Gen 2 as well. The variances don’t make any sense to me. I was, however, able to get it all sorted out and have all three axes properly aligned. I used multiple levels to get the job done but I just had to get all the levels to match within reason. The rest of the tuning can be done via shooting and fine tuning the third axis from there.

You can plumb your bow with a 4' level also.
Put your bow in a vice.
Plumb it front to back from limb pocket to limb pocket. Now that that's done, plumb out cant by setting your 4' level axle to axle and plumb it up, if you want to plumb the string just adjust your level so it's parallel to the string and plumb it up.

Personally, I haven't seen any benefit to plumbing the string vs plumbing axle to axle. My logic as to why, is that my D-loop is in a fixed position and doesn't slide up and down the string so what difference does it make?
