Thread: Planer/thicknesser

Thanks for the diag. Jack,
I'm still not seeing anything about setting it 1/16 below, definitely not in that diag. Nor in these.

are you referring to the number i use as an sample (in others words) to illustrate the process of making the gauge blocks? I never said to set anything but machine spec on/in his manual. it would be silly to give numbers other than the manual and i do not even know the machine or have I seen the manual. My comment was one of above or below school in terms of the pressure bar.

interestingly this is what the Powermatic manual says about rear pressure but in other manuals they say above for the same model ? its a running joke about that diagram you posted off VM that Powerematic is not sure

Maybe that's why Powermatic ended up buying the Wadkin setting tool for help with setting up.

As to what new planners do is just get rid of the bars altogether and move the rollers closer to the head and then to keep the stock from tipping use 4 are 5 rollers


it was hard to find one with a straight knife head as who would need a chip breaker with a helical head.

Ah!! So you planed off the 1/16" as a random act. OK

No I didn't get the diag. from VM and I have no idea if it is a Powermatic one.
It came out of a publication by Fine Woodworking on the maintenance of machines and I would assume that the guy was not intending it as a joke. I don't have the book handy to see if he drew it or used an industry one.
I used it because it shows the ideas that I have always heard were correct when setting up planers.

So Wadkin and Powermatic were both selling the same blade setting gauge in the 1960's, who invented it, how many other companies used it?

Same author same right up in VM as in FWW Allison But it looks like its a for a Parks planner sold by sears not powerematic

I assume Wadkin owned the design as it appears earlier in there catalog than in powermatic's. I know of no others using it or that had there name cast into it. I think once the planers that used the knifes setting jigs for the heads came out in the 60's (Bursgreen lines) the gauge was less popular from wadkin. I have never found information on any arrangement between the two party's. They are identical other than the name Wadkin Or Powermatic cast in the side.
