Hey guys, i am in need of a contact wheel for my home built 2x72, and have a few questions. I would love a ten inch contact wheel, but the price jump of roughly 150 dollars between 8 and 10 makes me wonder if an 8 would still be fine for me, and be cheaper. For now the wheel will be mostly used for hogging, however i would also like to be able to hollow grind with it eventually. Most of my knives are 1/8 or 3/16 stock, with the odd one going up to 1/4, but very rarely. Rarely enough i could just flat grind those ones. My question is what do you guys use, and what size do you think is the best? Secondly, i am stuck between smooth or serated face. They say a serrated is more aggressive, and hogs faster, but also runs cooler and extends belt life. The serrated wheel however says that it does not leave quite as nice of a finish at higher grits when finishing hollow grinds. Any advice on this part? Due to the cost of these wheels being roughly what it cost to build my whole grinder, i would like to do some research before dropping 300+ bucks on one.
