Now that I am at good wood I change the setting on the fence to the thickness I want the slabs for the blocks to be.
Since the ironwood is so hard the blade can wander a bit so I make the slabs a little thicker that normal.
Here I cut my 1st slab.
Then the 2nd one.
There is not enough solid wood for a 3rd one so I turn the chunk to see if I can get another slab off the other cut surface.
Lots of cracks in this slab but a portion is good.
Cutting away the waste from the last slab.
Looking at the 2nd slab there is a big crack so I draw a cutting line just inside the cracked area following the grain.
Trim away the cracked portion.
Then trim the other edge.
Finally trim the 1st and best slab.
In the end you see there is about 1/3 usable wood and 2/3 waste. Bear in mind this log had a whole lot less cracks than normal for Ironwood.
This is what I have from the foot long log section. Will probably turn into about 8 or 10 blocks.
A couple things to bear in mind
Always use a new sharp blade.
Wear a mask because the dust is a nasty irritant. Even when just cutting.
