That stuff is NASTY,boy do I have a truck for you ,my father in law has a old 59 Chev.1/2 ton that he used for a fuel truck for his hvy. equipment that has 4 diesel fuel tanks with elec.pumps that leak that junk all over the back and the insdie of the pickup.
In about 4" of sand and junk ,beer cans and alike. NASTY,NASTY he ask me if I wanted it and I said HELL no you can't get that smell out, he got the truck new and he has over 375,000 miles on it and it comes with a case or two of oil to keep the eng. running at peak. hahahahahaha I was with him one day and he siad I should check the oil and he said hey bud hand me 6 qts. I need to add some hahahahahaha.
That's just the way the old did it.
To get back to the Rabbet bit ,it will work great but you need to think about it just a bit.
Oak is a long grain wood and when you use a rabbet bit you need a Chip breaker
in the fence, you will see Bob and Rick do this all the time when they use one.
They back the bit into the fence and cut a pocket for the bit that puts a chip breaker in the fence, so when the bit that's running at 20,000 rpm. has a way to hold the stock and help the rip out when the bit comes out of the cut.
Think of it this way you have a saw blade that's 3/8" wide and when it comes out of the cut it will lift and rip the cut on the down side, it can be sharp but it will do the same thing.
Just a note about the allen screw that will not come out, they make may items to help get it free, I use the cap off one of them and fill the cap with the fuild and set the bit in it for a just bit and then remove the screw with allen wrech or the vise grips if all eles fails then just replace the screw with a good one.
BUT I will not use that nasty stuff "diesel fuel" or 90 gear lub that's also nasty and hard to get the smell out of the shop.
One thing being a gear head but to smell like one, well.
Have a good one
