Title: Converting Ribtek 190 into Single Bevel
Post by: John Scifres on August 13, 2012, 09:53:00 PM

I have been playing around with this tonite.  First off, I'm not sure which side I should be grinding.  I have left wing fletch.

I did one older head and got it pretty nicely ground.  It finished at 160 grains and a bit over 1" wide and 3" long.

Anybody else ever try this?

Look at a Catalog with a picture of the left hand head, Then you can copy it. No reason it shouldn't work. Myself , I kind'a like Ribtek's the way they are....lol. Let us know how you make out!

With the point up,the ground bevel should be on the left side for left bevel/left wing fletch.

been shooting ribteks since 90s.....have a bunch of 160s and 190s....love them.  I bought some Grizzly Kodiak 200gr I am trying on our whitetail season that starts in two days.....

interested to see how they work for you....but yeah, go to Grizzly or another site and copy grind based on their pics for a left bevel since you have left wing fletching.

I too like the ribbies like they are...hold a good edge, sharpen easy once you get them done once....and put a tanto tip on them and they are pretty tough on anything.

good luck

This is a right bevel

Well Poop!  I guessed wrong.  Anyone need a slightly used, kinda bent, right hand bevel Ribtek 190/160?   :)

Thanks for the help.  I've been rereading the Ashby research and find it compelling.  I am switching from a 55# bow to a 47# bow this year and am looking to maximize effectiveness where I can.

I ground the head into a left bevel.  It is now 147 grains and maybe a tick over 1" wide.  It looks pretty wicked.  Maybe I'll shoot it into some bone and see what she does.

John:

Good luck with your conversion.

If you need some more 190's let me know.  I've got a dozen I was try'n to sell.  6 have been sharpened and 6 are brand new.  Let me know.

Thanks.

The one thing I would watch for is the fact that some broadheads have hard enough,tough enough steel to support the low angle of a single bevel edge and some don't.If the edge chips or curls,any possible advantage is lost.Some heads may do better as a double bevel.Shooting into wood or bone may give you an answer.

That brings up the angle.  I had some Grizzlys that I just matched the angle on this one.  Seems strong.  I'll shoot it into some plywood tonight.  Just for fun  :)
