Really like the oak... nice grain and good design.
On the CG mills, I don't cut the tabs off. After I finish with the drilling, I have a relief tool used in chasing threads that I cut a groove inside the body and inside the top to take the tabs... prevents them from pulling out even if your glue fails. I also use epoxy to glue the grinder and cap piece in place, just as a double precaution.... I've only had one mill fail in 10 years and it was glued with thick CA, not epoxy... it was one of my earlier ones and before I started cutting the tab groove. .
The thing I like about the CG mills, you're not restricted as to your blank size... you can do any thing from a 6" to about 13" with the 10" shafts and if you buy the 18" shafted mills, you can go even larger.
I also only use 3 drill bits instead of the 4 called for... I use the 1 3/4 for the very bottom, then switch to the 1 9/16 and drill through with it. For the top, cut a 3/8 to 1/2" tenon just under 1 9/16 to fit down inside the top of the body and gives the top some stability... the top is drilled with the 15/16 bit for the white piece in the top.
To cut off the shaft, I put the top on the shaft making sure it's down all the way, then measure from the top of the body to the bottom of the top where it will sit on the body, then transfer that measurement from the end of the shaft towards the body, then cut it with a large pair of pliers that has a wire cutter in them, then grind the end of the shaft smooth on my bench top belt sander.
BTW, don't know where you buy your inserts for the crush grinds, but I've found the best prices from Cam Levers out of Canada... even with the Canadian post shipping charges, the per unit price seems to be lowest... plus if you buy 10 or more units, he will throw in 1 more unit.... for me in TN, it makes the unit cost under $15 each when I buy 10 and receive 11.
