what'd you get? I have both the Griz Baby Drum and the Jet. Prefer the Griz; the Jet is backup. Some of us do the parallels direct on on the machine bed and do fine. Last couple of years, I've used a taper sled I made myself with the drum sanderwhen i first got it... (.0015)) not perfect but works fine if you pay attention and rotate it. Now I've gotten a set of the machined aluminum sleds through that deal Kirk put together a few months ago. My project for this week is to use them to tune the machine (3 years use) and make a new taper sled that's more accurate.
I believe Kirk is putting together another order for these. Spendy but... Alternatives are: 1: instead of buying lams, contact Kenny and he will sell you a sled; 2: just go ahead and make one... 4 1/2" wide chunk of clear hard maple 40" long. Determine taper you want: .001 , .0015 or .002 x 40". grind a piece of wood that thick and prop up the board, then run it through your drum sander till you get a full length bite. Now it's a sled!
Good luck!
