RE: Help setting up a spiral head in planer? - ®smpr_fi_mac® - 09-15-2017 I'm not missing that point. My problem is *finding* that point using measuring tools that aren't rigid. I can't rely on the diameter of the head because I don't know the tolerances it was cut at *and* it isn't a round cylinder. So I figured out another method. I cut a block of wood to fit under and slowly raised the bed, spinning the head slightly until a cutter at one end contracted the block. Then I moved it across the head and adjusted the table until that cutter hit in the same place. Then used the block to set the pressure bar. Then cut another block that is 1/32" shorter to set the rollers. Let's hope it works! RE: Help setting up a spiral head in planer? - JGrout - 09-15-2017 Quote:I'm not missing that point. UH what pray tell are you using to do the measuring with A simple gauge block and a feeler gauge are about as static a measuring system as there is You really need to get past the whole I have to measure to a spiral chip and use the solid round block of steel that carries all those little chips That is you first point of reference the second one is the table itself and that is is the one you make adjustments to It is really too bad that you did not make all the adjustments to the planer _before_ you took out the old head , you would not be so lost right now RE: Help setting up a spiral head in planer? - ®smpr_fi_mac® - 09-15-2017 What adjustments would I make? The cutter radius in the new head is slightly different from the old; the old adjustments wouldn't work. To do the measuring I'm using a method taught to me years ago -- a dial indicator mounted on a block of wood. Works great for straight knives. A bit difficult for spiral cutters.

Secondly A DI is not the measuring device to use to set a table parallel to the head............ the block and a feeler gauge is much simpler and the chance of making an error is like a thousandth or two depending on how you push the feelers in place.... A DI is not in this case the correct tool for the job.... It will work just badly RE: Help setting up a spiral head in planer? - ®smpr_fi_mac® - 09-17-2017 Yeah, once the solid block idea hit, setting the table, chip breaker, and hold down bar was easy. Both the chip breaker and hold down bar are perfect, I think, as any lower and the wood jams in the planer. I'm still getting snipe at both ends. The tiniest bit at the trailing end, which I might be able to live with. A bit more snipe at the leading edge, though. It's not terrible but I'd like to get it closer to gone. So a little more work to go. Thanks for helping! RE: Help setting up a spiral head in planer? - Stwood_ - 09-17-2017 Always measure off the head RE: Help setting up a spiral head in planer? - ®smpr_fi_mac® - 09-17-2017 I'm not sure what that means.

How? RE: Help setting up a spiral head in planer? - JGrout - 09-17-2017 (09-17-2017, 08:48 PM)®smpr_fi_mac® Wrote: Shimming under the table gets rid of sniping? How? lowers the table rollers well I may not have said it correctly you may have to remove shims under the table rollers It has been too long since I worked on a 100 so things here are a bit fuzzy Joe |
