there is a place in OHIO that will re lap a diamond nit.. it cost about 20 bucks plus shipping.. it comes back lie new.. if it is beyond repair thy tell you up front.
also the cobra lathe is def the best bang for your buck..Just make sure everything is set right on the base.. i had two fo them where the blocks were tweaked and it cut terrible.. cost me a few bucks to have a machine shop re set it all.. the Hudy is what i have now.. With bearings.. I love it.. never had any probles over 3 years of use..
PS The cobra lathe requires the motor to be hooked up backwards.. IE pos is neg and neg is pos.. i seen three guys blow a diamond on the first cut from hooking it up the other way..
