new at this so I have some a couple of "dumb" questions. How do you get a gauge next to the arbor to measure its run out since the arbor is suspended below the saw bed. The arbor on my machine has been modified to accommodate a dado set so I am interested in checking that first. I was thinking of setting the gauge on the table surface and measuring the distance to the saw blade as I rotate it by hand but this would include the blade's plate variations as well as the arbor's wobble. Also how to do measure the blade's plate flatness? ----- Original Message -----

I'm running an '88 BF-5 - has a scoring unit, but I haven't bothered usingit 'cause I'm getting great cuts without splintering - NB: I'm not running melamineor 2-sided plastic laminate at all, thank God, and I'll use the scorer if I do! -here are the secrets I know.check a # of blades from the same manufacturor, and you'll find quite a bit of latitudein the plates. If you get something within a couple of thousandths of flat,cherish it, and use it for your finest cuts. I'm running Felder's 96 tooth "SilentPower", which does a good job of non-splintering, and a 96 tooth Tenryu (stock blade, made tofit Altendorf) that cuts perfectly-best I've ever used! At about $140 it's alittle less expensive than the Felder. Don't mess with a thin kerf - some cut clean,but mostly the thin plate distorts when overheated, I'm sticking with only 3.2 mmkerf - saves resetting the fence every time I change a blade, too! Obviously,razor-sharp (and with sides of teeth jointed during sharpening) matters.badly if the arbor's out - change bearings, if necessary, or have a machinist recut thearbor face accurately.machine. The BF-5 blade sits several inches away from the slider, so I can make aninsert, but haven't needed to.cut. The hairline cuts seem to want to splinter worse.raised as high as possible - this results in the tooth meeting the underside of the panelas near to parallel (no angle...) as possible, and will help minimize chip out.cove-faced tooth configuration works well when sharp, but cut quality deteriorates rapidly,and tend to go from workably sharp to dead-dull without a moment's notice!avoid! -Philip Tamarkinbought planermy 7-41 so I made some Rookie mistakes. Two features I am thinking of scorningbed which you mentioned and a scoring unit. Of the two I think the tearunit is the best buy since I have not been to achieve the quality of IIout free cross-cutting on the Felder that I had with my own Woodworker rentedthin kerf blade I used on an old Delta in the cabinet shop where I wasshop time. I have used a new 10' thin kerf Woodworker II (the old one adjustreplaced by Forrest when they found that their jig had gotten out of 12"for drilling the pin holes in the old one), a 12" Woodworker II and a tearFelder blade and a zero offset insert. None of these blades produce a reasonout free cross-cut Although the tear out is very small. I think the allowfor this is the position of the insert next to sliding table doesn't wrong,enough support even with a zero clearance insert. If some of the more loweringI would appreciate hearing from them. My work- around is to set the theand locking the jointer beds in place. I usually mill several boards at requiressame time and after jointing I run all of them through the same planer bedgoing back and forth from the jointer to the planer, lowering the planer muchwould get old fast. An option I would suggest to stay away from is for planertied up in it as one of the above. ----- Original Message ----- in(not the numeric panel - only the buttons).
