I done a lot of mortises by hand, and it gets easier the more you do. Here, the wood isn't very dry so the choping isn't too bad, especially with a lot of the wood taken out with the drill bit.
</font><font color="blue" class="small">( So, what made you decide to do it as a timberframe? Are you thinking of building something bigger and wanted to get a feel for it or are you a timberframer and just felt like doing something for yourself?)</font>
My wife and I had taken a timber framing course where the class built one of the bents and some rafters and beams for a house during the week then we raised it in a weekend, and I wanted to put the skills I'd learned (design and build) into action on my own project before they got stale.

Timberframes aren't really made to be out in the weather. An old barn will last forever as long as you keep a roof on it.
Building anything timberframe appears to be much the same as building furniture only bigger, but the design considerations are quite different. Specifically, you don't domension the lumber, only the building. Some interesting measuring techniques which are easy to forget.
