G'day everyone,
I think I first saw a Clickspring video back in 2015 and since then I've had the urge to make one of those big fly cutters that he has for his workshop. And since I have a project coming up where I need to face some large pieces of steel bar stock, I couldn't help but jump at the opportunity to make one for myself.
It is effectively a big 200mm piece of 6061 aluminum bar stock with a morse 3 taper arbor and a holder for the carbide insert. However, the project wasn't as straightforward as I thought it was going to be. The bar stock was a little big for the 130mm chucks I own, o I had to do a lot of the roughing on the mill, turn down the arbor and hold the arbor in the spindle bore to turn it down.
In the end I end up with a fantastic tool, even if it is not as fast as a smaller fly cutter, the finish I can get is much finer and closer to that desired mirror finish. I hope you enjoy the video.
