I can't buy it, it's on a Massey Ferguson corn planter from the 60's. The only screw augers I have found have all been one way, I need a left & right hand because it feeds from the center out. I think I will try and make it myself, thanks for your info!Easiest to just buy the part, but if you have to make your own...
Use the old one as a guide and tack the end of the stock to the old auger. Now, heat the stock along the outside edge red hot perpendicular to where the stock contacts the shaft and bend the stock around the shaft. You only want to heat that area. Take your time and use clamps every once in a while to keep things straight.
