Re: Cutter head to outfeed table specification on A3 31
¿ªÔÆÌåÓýFWIW, Here is a table showing the variation between outfeed and Tersa cutterhead and the knives on Dual 51. ? This was after I cleaned the slot and knives which improved the results. ? ? Imran Malik IAM Wood Creations ? ? From: [email protected] On Behalf Of Patrick Kane via groups.io

My no name?500mm jointer is also a tersa head, and i never stopped to consider not all tersa knives are the exact same spec. Are the carbide knives taller than the M or HSS knives? Kinda silly of tersa?if they are not consistent across the different steel types. That is somewhat of the selling point of the system. I havent?taken an indicator to my machine in years, but maybe i should.? ? To the OP, on a 12" machine, you should be able to hit .001" projection across the width of the bed. I found that to be fairly difficult on my machine. For example, the fence side is maybe .001" lower on the outfeed table. It is a delicate dance making the cutterhead body parallel?to the outfeed table and then the infeed table parallel?and coplaner?to the outfeed table. It is so easy for one adjustment to move a previous adjustment by .001-.002". You really can chase your tail for hours. I wouldnt?sweat it too much. Get it as close as you can and then just start working. If you have bad snipe or your workpiece is snagging on the outfeed table lip after the initial 1" of cut, then go back to adjusting. Im all for calibrating your given machine to the absolute best of tolerances, but you can drive yourself crazy for zero appreciable difference. For me, a .002-.003" variation across 12" is the "good enough" point for most machine setups.? ? Patrick ? On Sat, Jan 11, 2025 at 3:02?PM Joe Calhoon via <joecalhoon=[email protected]> wrote:
