Precision #2 Morse Taper x 5/8" Diameter Expanding Mandrel
I bought a mandrel from Flint Hills Duck Works, and this thing is great. I had fought with not-centered game calls, no more. Everything is dead center and it is worth every penny I paid. stevethenurse 3/2/07
This is the Flint Hills Duck Works precision expanding wood lathe mandrel used for making duck and goose call barrels with a 5/8", or 3/4" bore. The work holding attachment is available in #1 & #2 Morse Tapers to fit standard mini lathes. The Morse taper accepts a threaded draw bar if you choose to use one. I recommend using a draw bar anytime the tailstock end is not supported by a live center. The use of a drawbar prevents the mandrel from "creeping" or coming loose from the headstock spindle. If you do not have a drawbar you can easily make one using a piece of allthread with a washer and a nut. The bottom of this page includes pictures illustrating the "drawbar" concept if you need further details. The expanding part of the tool is made of 360 brass. The brass expanding shaft portion of the mandrel extends approximately 2-1/2" beyond the shoulder stop. This design allows a good solid grip on your call blank but it also allows access to the end for tapering and sanding the inside of the mouthpiece.
Once your mandrel is inserted into the headstock of your lathe you simply slide your call blank onto the expanding brass shaft and then tighten the hex head cap screw approximately 1 turn using the 6" T-handle hex wrench (included) to lock it in place. The knurled expanding jaws provide unbelievable holding power. This is a far better method of turning versus those cam and pin style mandrels which work by eccentric action that forces your workpiece slightly off center. This design also allows for quick reversal of your workpiece for access to both ends. The end of your workpiece will not require the support of the tailstock for normal turning or sanding however extremely deep cuts should only be made with the support of a live center on the tailstock side.
Years of experience has taught me what works and what doesn't. I have had such success with this style of mandrel I decided that I should make more for other call makers to enjoy. My machining method results in a mandrel with less than .001" runout. I guarantee you'll find this mandrel will eliminate most of the common frustrations associated with turning your call barrels & I stand behind my product. If you are not 100% satisfied simply return the mandrel within 7 days and I will refund the full purchase price less shipping charges. All of my calls are all made using this same precision expanding type of mandrel. If you have a larger or smaller shaft size requirement please contact me and I will be glad to make another mandrel to your specification.

I wanted to let you know how much I appreciate your mandrels. The 1/2" I just got works great. The 3/4" one I purchased a few months ago has gotten a lot of mileage. These mandrels make call turning fun again.
