Best saw cut of my career

I needed to make a spooning die a while back. I had to machine a piece of round tool steel stock to 1.865 diameter, then split it lengthwise on the vertical bandsaw to get half to use as part of the die. Using a straightedge and a scribe, I marked a line down the length of the material, then went to the saw to perform the cut. This must have been a day when I was in "the zone" for the freehand cut to come out this well. If you have never tried to equally split a piece of cylindrical material freehand on a bandsaw, while keeping the halves equal, and with a flat plane on the cut, then you just won't appreciate what it takes to do this. The pics below show the piece. It is 3 inches in length. The blue end measures .9135 thickness, the middle is .915, and the far end is .918. The face plane is flat enough that the part will not teeter when placed face down on a surface plate. I feel that I will never make a freehand cut of that quality again. I can die a happy man.

That is a nice piece of work. For those who haven't tried it they have no idea of just how difficult it can be. Steady hands for sure. Obviously you took your time and let the tool do all the work. Nicely done.

Tack weld it to piece of flat stock then you can use a 90 degree fixture to guide you through the cut.

Have to do this type of cut all the time. I ain't talented enough to do it free hand

What you didn't say is that immediately following that perfect cut you discovered that you mis-read the funny paper and made the dim .1" too small.

My "best work" always seems to be the stuff destined for the scrap bin.

:D

LOL, luckily for me, I design and build on the fly, using only my personal sketches. However, I DO have that special clamping ring for disassembling a cylindrical machine part that I bored .100 too large. :wtf:
