A great chair joint is what I and many woodworkers call the Maloof joint...it is the one where the leg meets the seat. It looks intimidating , but actually is an easy joint to make and a great one for chairs and sofas...etc. I thought this may be helpful as we get more into chair making. It is made with a roundover and a matching radius on a rabett bit. If it comes out tight and is the shoulder just lower the bit a touch...This is a good one to have in your arsenal, it is very strong and with a couple of screws and glue, your cookin'...and it does not mean you have to copy the whole chair...enough woodworkers already do! Wish I could take the crredit for this one, but just thank Sam...the Master!
