DoveTail issues

Hi, I am making the dove-tail box from Tasmanian King Billy Pine. Athrotaxis selaginoides. Beautiful straight quartersawn piece. I can count 200 growth rings in just the piece I have which is not the full width of the tree.

But i am having trouble with doing the chisel work on the dovetails. Because the timber is so soft it is crushing under the chisel, rather than cutting the fibres. I have sharpened the chisels, I can shave my arm. Any suggestions

Oh I know the feeling! I worked with Southern Yellow Pine once and it was very much the same thing!

If you're not already, I would encourage you to cut as close as possible to the line with a coping/fret saw (Less than 1mm) Also avoid using a mallet when chopping out the waste and instead pare it very carefully. Taking off no more than half a millimetre per chop. It wont eradicate all your issues but I'm sure it'll make it cleaner.

Does that make any sense?

Try using a 17 degree bevel on your chisel.

remember, the crush will be hidden in the joint.  Had the same issue with eastern white pine.

Rob Cosman has a video on that.  Of course, you'd want to use a dedicated chisel for that because it would be way too thin and brittle for everyday work.
