Bat house Bat box or Bat condo

Great job. I built one a couple of years ago but yours is beautiful.

We have a massive mosquito problem here at the Jersey shore and we need to get the bat population up.

Nice bat house, super fine double dovetails. Like the jig for the bandsaw, reversible too. Slick.

Are you sure that box will hold 800 bats?, seems kinda small for that many.

You are probably correct about the 800 bats, although they are 3/4 inch around and they pack themselves in to keep the temperature at around 98 degrees.
I was guesstimating my number at 800 because the four chamber as in the plans held 600 bats.
Thanks for the kind words guys.

Nice! I liked the video. Slick jig.

Very inovative in it's simplicity.

Vince, could I suggest adding some pics of the jigs right here? I would love to hear you explain what your doing next time in the video, these are the things a rookie woodworker like me have a tough time wrapping my head around. Great project and will have to build one for my backyard as well, is there any recommended height and place to mount them? Thanks Pat
ps did you make the blade for the plane?

Pat, My jigs are not "finished" , I will post detailed pics in my blog, thanks for thinking that I am not a rookie, I still am, in my mind. I just plod along at my own pace.
As for the dimensions I think mine was 25" high (plus a 10" landing board at the bottom) 24" wide and about 9" deep I got to this size using all of the boards I had on hand. I bought five more 5/4 8 by 8' cedar boards to resaw the baffles inside and the roof and landing board.
I had a Victory plane blade that I thought was near worthless. With nothing to loose I sprayed black paint on and then marked the teeth with a scriber. My Dremmel with a square grindstone and me with patience cut the teeth. Honed the teeth just like a regular blade. I know this sounds like a lot of trouble, but I love working steel and did not want to listen to my table saw whine for hours on end cutting all those grooves! You can see the sweet result in the video.
