corigated slabs
i gave my chain a good sharpen with the electric sharpener and whaen i cut a slab off the camphor log it flew threw without me pushing it at all and was bringing out ribons. but i ended up with this.
the problem was that it was cutting to fast on the next slab i held back on the saw and ended up with a beautifull finish.
has anyone else this happen?

Kind of. I think it happens when you push too much. This was only with a little electric CS and full comp chain, so I imagine if it was a big powerful CS with skip-chain, the corrugations would be bigger.
First pics are letting the saw feed itself, and the second lot of pics are pushing it hard.
Do you pivot you're mill when cutting?

not usualy.
i think it was because the chain was so sharp as i said i had to hold back on the saw to get it cut neat.
it was realy good.

the groves are at least 4mm deep.

Weisy,
What is the shape of your bar/chain? I wonder if it is the chain is unevenly filed and/or the bar is uneven, ie not square, and/or bar is old and groove is too wide open, pushing the saw can drive/force the chain over on its side and produce corrugations. Easing up the pressure would let the chain ride better in the groove and give you a more even cut.
OR
On reflection maybe the stuff was so soft you were just churning through it too quickly. Its nothing a thicknesser wouldn't fix in a couple of light passes.
Tim's right - I can see why skip chain would make the corrugations worse.
Here is my finish on sheoak, somewhat scratchy, but chain is full chisel.
Cheers

The first couple of cuts with a freshly-sharpened chain on the Lucas nearly always end up corrugated quite badly. i usually make the firt couple a bit thicker for that reason. I'm running a 5-skip chain, but am about to try out a 3-skip and might go all the way back to a 1-skip in the search for the perfect cut. It doesn't seem to matter what sort of timber is being cut, either.
Cheers,
Craig
