I’m sure this has been discussed, ad nauseum, but I haven’t found anything relevant in a brief search. A link or even search term help would be appreciated.
I have some fir lumber, both new and old. The old stuff is really old. Old growth. It’s like hardwood.
It has been drying in my shop for three years. My moisture meter isn’t particularly trustworthy but it shows in the 5% moisture range.
Most of it was recovered from a house I demolished some years back but it has been cleared of nails.
Even in areas where the grain is perfectly straight, it chips out. I’ve tried both the really old stuff and some stuff that has been drying a couple of years old.
I’ve been trying to mill a 1×3 with a bull nose. I don’t have a bull nose bit so I’ve been using a 3/8” roundover. It has been chipping like crazy in areas where the grain is being slightly crossed (just a few degrees). Climb cutting helps in these areas but with the grain not being perfectly straight, I would have to climb cut/straight cut in tiny increments. It would take forever.
I’ve seen plenty of nicely milled fir, so I know it can be done.
I’ve been contemplating using a humidifier to bring the moisture level up closer to 10%.
Thank you in advance for any help! :)
