Milling with progressive rakers

[AaronB]

For those of you that use progressive rakers, is there a way to check for it without using a file-o-plate. Is there some type of system I could use to get them down correctly, like if the tooth is this long the raker should be this much lower.

First of all your gonna need a daf and a caliper if you want to get up to speed on here. I'll save you all the misery of trying to figure out what that is. I layman's terms its a Digital angle finder. I think BobL or Mtngun will be about to point you in the right direction on how to use it.

The grimy detail is described here.

Post 41 in that thread has some pics of using the DAF.
Post 68 has a link to a vid of me setting the rakers.

Awesome I will check out those links. I have two of those DAF already from my woodworking so now I have one for another use. I have one set of calipers, again for my woodworking, but its not digital and its in inches, I believe broken down into 64ths, but I would have to check.

Its this one.

One question I do have, the angle that you show with the DAF (around 6°) is supposed to be the same throughout all the sharpenings, correct? So if I sharpen the teeth, then put the DAF on it I can take the raker down to get the angle, then repeat for each raker, correct? Just trying to make sure I understand the progressive deal.

You got it.

BobL,

Upon reading the entire thread, I believe my above statement is correct, but what is the mark on the bar for, what are you lining up at that mark?

Yep, just move the cutter/raker to the same mark every time.
