Koren Hybrid Wheel Update

So I started building a Korean Hybrid style wheel that I drew up some plans for...

I purchased remnant metal from the metal yard to fabricate the base and main rod from which the wheel is supported. I cut the pieces yesterday and welded them up today making sure that they are FLAT, SQUARE, and that the vertical rod is PLUMB. The finished base is 28" square and the rod is 35" tall from the ground, which I am going to cut to accommodate the perfect height.

At the top of the rod I have a 1" section which I have drilled a 90 degree countersink into creating a perfect "V." This piece is separate for two reasons, the first is that it is much easier to drill a 1" section of rod on the drill press than a 36" section of rod, secondly and most importantly...I am going to harden this section of steel so that it does not wear out as easily as stock mild steel would. Once hardened, this section will be welded back on top.
Here is the "live center" with the morse shaft cut off, which will be inserted into the wheel head and will mate up with the counter sunk cup.
This is how the mate up! they only make contact at the very tip, which creates very little friction = easier to turn and keep momentum!

More to come!
