I’m very happy to be in possession of a couple of nuts from Lake Erie Tool Company. They’re beautifully made.
As I mentioned to you in a previous post, I highly recommend that you buy your wooden bench screws and nuts from a vendor who is set up to manufacture them on a production basis. Okay, the screws are easy enough. Make them if you want to, but I’m still suggesting that you buy the nuts and save yourself a whole lot of headaches.
Then I figured that I could use my “lunette box” from the screw making machine. I could use the same lead screw. All I had to do was make a hub with a couple of stand-offs to support the nut blank.
Then I’d use a center plug and mount the blank and simply slowly turn the blank into the flycutter and voila, a perfectly formed nut.
Okay, pull the plug, turn on the cutter, turn the leadscrew….
Then it all went awry. Cumulative clearances, an over-extended leadscrew, a “too thin” cutter all came together to form the perfect storm. Overwhelming vibration set in. And, try as I might, I simply was not man enough to restrain the whole thing. I did succeed in creating several nuts, all of which were over diameter and not nearly concentric.
Though I lost a couple nice pieces of hard maple, I was reminded of a valuable lesson: failure can be a much better teacher than success, assuming that you can kick your ego out of the room while the class is being held.
So, once again I say unto you, make a screw, buy your nuts.
I think I’m gonna try to repair my old wooden tapscrew. What the heck?????
