Title: Anyone ever tapped a Magnesium Riser?
Post by: DanielB89 on May 08, 2017, 11:36:00 AM
Has anyone ever tapped a bear magnesium riser for a side mount quiver?  


I am looking into quiver options and the side mount just seems like the best option for it, if it can be done.  


I have an A mag, so its rather short.  I am not sure if I want the standard insets to accept a quickie quiver, or is I want one that will accept a side mount from one of the sponsors.  Looking for info.

Daniel

Magnesium alloy like that should be pretty easy to drill, probably softer than steel.  You could either carefully drill holes for quiver inserts...just make the holes ever slightly smaller than the knurled part of the insert and then tap the inserts in making sure you do it straight, or if they won't grab/hole ever so slightly too large just epoxy them in.  You could also just drill the holes and tap them directly, but I wouldnt if you thought you'd remove the quiver often, as the mag threads might not hold up to repeated use.  A drill press or drill with a level or a real good eye could do this project.  Use a small pilot bit and then work your way up, drill steady without heating up the bit.

Binghams or 3Rivers sells inserts etc.

The mag risers tap well, just go slow, use lots of oil, and clean the flies constantly.  I tapped a Darton Mag riser earlier this evening for a bowfishing reel without any issues.

Try tapping it. If the threads pull out redrill and add an insert.

Have any pics to share?

I also see that I may have misused words.  Instead of tapping it, I really mean drill a hole to insert some quiver inserts.  


I am going to try it soon if my current quiver situation doesn't work out.  

Still trying to refinish the riser.  Should finish that up today.

I personally would drill and tap but I'm sure an insert could be used but I don't know why you would.Don't forget,the thinnest metal is behind that sight channel,so it may not be thick enough there.

I put inserts in mine. No problems. Do it just like any other bow. I do like to put a little super glue gel on the insert before pressing it in place.

Let us know how it works out. I had an expensive lesson with my B riser. The bottom bracket pulled loose on me. The screwswent one way the limb another. I bought steel inserts and the kit to install them. That cost me $70 and some strange looks from the "biker" shop guy. Reason I went with the steel was they are used in carburetors when repairing them for race cars.

DanielB89,
No pictures of doing the actual tapping.  Here is a picture of the finished product, the reel on the riser.

Your best bet on both A and B is just knock out the medallion form inside the sight window. Its usually just pressed in there. Tap with a pin punch and soft hammer or mallet.
Then drill hole to 1/4". Put a 1/4" nylock nut in the groove and either make or adjust the brackets on your quiver and simply bolt to the nut.Use the other bottom built in thread as is. It's 1/4" too. I use hex cap screws. If you ever decide to sell it just hot melt the medallion back in.

I would drill and tap it for a helicoil insert which is stainless steel,strong and better than screwing in and out of the magnesium. Magnesium is much like aluminum only lighter ,I work with metal and I don't recommend drilling a hole and force fitting an insert that is for wood it will most likely pull out in a short time

I bought a B-mag a couple of years ago and it had two small holes in the riser that were spaced to fit a kwikee kwiver bracket but they weren't tapped. So I tapped them and put a bracket on it.  Never gave much thought that it might not be strong enough.  I like a kwikee kwiver but only until I get in my tree.  Then I take it off.  Working so far.

You are correct, the thread are not nearly as snug as when tapping steel.  I agree if you are going to take the quiver on and off.  For me, this bow will only be used for bowfishing, the reel seat will not be coming on and off of the riser.

I tapped an old bear compound riser for a quiver.  I used the 1/4 x 20 inserts from Bingham Projects which require tapping as they are threaded, a bit of epoxy and it is good to go.  Hint a little tape on the bottom of the insert will keep epoxy from getting into the threads, doesn't take much glue.
