We talked it over today and didn't get some time logged to the job.So that puts the cost to just shy of 9 bucks.With you making,selling them for $22 that is reasonable.I would use a step drill ground with a 1/4"O.D. pilot 3/8" long to 1/2"O.D (1/2" colbalt stub drill)just because it is cheaper than the step bit you are using.If some of you guys are like me and drop the son of a gun on the floor then you can resharpen the pilot on a bench grinder like most drill bits.either way buy polarisriders kit or make your own,use it on your own sleds it works,you are done.(put it where you can't find it to do your next sled or your buddies then buy another)LOL keep smiling,think snow,
