Thanks for your reply. I am still learning.. a lifelong process. Didn't know a whole lot about timber framing.. discovered that this house was TF about 6 yrs ago when I had a new roof put on. I bought house from HUD, it was going to be torn down if no one bought it.
When I did the prior fix, it was priority to get something done fast, before someone fell through! I thought I read my span chart right when choosing 2 x 8's. I didn't bridge the joists, and I think I should do that.
It would be neat to redo the joists using TF techniques, and leave them exposed, problem is, the house has been retrofit for forced air heat and electricity, and the ductwork and wiring would have to be moved.
