PS: you never said if you are jig sharpening or free handing. Come on . . . you can tell us . . . don’t be shy . . .
The guys make fun of me all the time and call me insane and worse . . .
do I care ?
(it hurts but I soldier on none the less)
No really it will only be some, the other camp will be carrying you around on their shoulders and calling you their next leader. In their minds anyway.
Right ?
so come onnnnnnn tell us . . .
I”ll have you know I gave up my fourth episode of MacGyver tonight to post this.
Ha, ha
You see Queenmasteroftheuniverseandbabybunnytrainer has been at some evening art classes and gallery doings so when she does that I get to watch my MacGyver episodes when I get home from work. I have all the seasons on DVD. It’s a lot of episodes.
Tooooo violent for Q so she prefers I don’t watch when she is around. I understand that. No prob.
annnd I like to watch them while the sun is still up. Just one of my weirdnesses. I really hunker down and get into other projects after the sun goes down. I’m a night owl . . . annnnnyway . . .
I was about to watch my fourth episode when I took a little break, you understand, and looked in at this thread to see how it’s going . . .
and the rest, as they say, is history . . . or soon to be if I can get past this intro . . .
I never say this when I am just talking but I gotta use it here . . .
"Look ". . .
forget the skew. That effectively lowers your cutting angle. My intuition tells me what is going on could be that there is a gap between the plank / work and your bench. When you changed the way you pressed down (when you skewed the other way) then you effectively pinned the board and closed up the gap (or some such) and the gap was allowing your board to flex or teeter under your plane contributing to the chatter.
Ha, ha, ha, ha
You backed off the chip breaker and the cut was better. That’s priceless.
As I always say the best gap between the chip breaker and the edge, at least in my shop is about twenty FEET. That is where my shop door is. Wedge the chip breaker under the door to help hold it open. That's my strategy.
NOW
In the photo are anti flexy tools. The rectangular flat strips on the right are basically thickish writing paper cut offs that I am always producing as scrap (I won’t go in to why). I grab a hank of these and stuff them into gaps.
the wood things standing on edge so you can see the thickness are 1/4 inch plywood scrap (center) and two door hanging shim / wedges. Lastly the white trashy looking cut out thing is just plastic display card that comes around various products. I save them for shim / padding for various tasks.
When I plane I plane on a very flat bench. Where ever the plank teeters and has gaps I place various combinations of this junk under it in the gaps so there is NO flexing and no teetering. That takes care of some of the chatter but more importantly allows me to make the planed surfaces flat rather than have them go from convex to concave and back again with each plane stroke.
Could this be happening with you ? Is your bench flat ? If you plane on a bench that is out of flat and then move the work to another area and plane again the work COULD . . . PERHAPS . . . flex and cause chatter just when you got it all adapted to the previous bench surface anomalies.
Varitas straight edge ? ? ? ?
I have two aluminum ones for checking for flat (not rulers). Mine are not flat / straight. Be ware.
And over all with one of my bevel ups I could plane straight on, skew to the right, skew to the left . . . it would make no difference. Now if I were cutting across the grain say on a raised panel then a skewed BLADE would be a good idea but all this holding our tung just right by skewing one way or t'a other is just . . . how do I put this gently ? More bevel downness.
