Not sure what I should do, got this riser rough cut ready for shaping, strung it up and drew it a couple of times. There seems to be some flex in it. I am not sure if I can just feel it because of all of the rough square edges or if it actually has a lot of flex?

The riser is African Mahogany, with two Rosewood I-beams and some mystery wood I had lying around for the curved accents. No glass at all. All the glue lines are good.

Should I go for it and finish it or be safe and scrap it and use better wood next time?

Thanks

 

 

What does it look like face on?

it looks good and thick, how heavy is the bow?

Here is the front of it, with tenative shaping pattern. I am thinking about putting another piece of rosewood on the other side of the sight window, ledt side of the picture

oh, and the bow should be around 45-50#

Mahogany can be a little brittle. If you're not comfortable with it, you could always set it aside for use on a lighter bow. It would be a shame to toss such a nice riser.

Mahogany can be a little brittle, X's 2.

I used it once for a riser and it separated.

I don't know much about making glass bows or risers for them but it looks to me like it has enough "meat" to support 45#. The lams in the riser give it a lot of strength. You could add another thin lam to the back side for more strength.

Well, shaped it, strung it up, put about 50 arrows through it, and so far I am happy with it    I heard that mahogany was brittle which is why I put so many laminations in it. I have a bunch more of the stuff that I got from a guy who made and fixed guitars. I think for the rest I will use glass and uae either actionwood or phenolic for an I-beam.

Juat have some file work to do to knock off all the edges, then a lot of sanding and finishing

Looks good. I can't wait to see it finished.
Dave.

got her sanded and finished, this mahogany POPS with finish on!!! pics don't do it justice

nice bow

awesome job,
very pretty riser,
but gotta say man, last time i saw a pic of feet on here, they had nail polish on- ala Hova        
but your feet are ok, no  matter what Roy says about them!

but i am curious, is it day lighting thru on the innermost limb screws?
is that not giving you the feeling of flexion

Good points, Wayne-O Boy..  

Very nice!
Dave.

Laminations running both ways and the riser having plenty of meat to it I wouldnt be scared of the mahogany at all.Thats a really nice riser.

Fujimo, these limbs have a clear plastic spacer in between the limb and the riser. Also, being an ILF riser, I backed the limb bolts out 2 turns to reduce the weight a little so there is a slight gap in between the riser and limbs. I definitely feel some flex in the riser at the grip but it is a lot less now that everything is shaped. I shot it a lot today and it shoots really nice

cool...nice job!

You will be hard pressed to build an all wood riser that doesn't flex a good bit. Wood and narrow strips of phenolic will just do that. Doesn't mean your going to wear it...although it doesn't mean that you couldn't either.

Backing one with glass or phenolic will at least help hold them together, but composite I beams take out a ton of flex.
