The Christmas bargain bug bit me.
I purchased a vibrating saw.
I have had several instances where a circular saw wouldn't fit and the sole plate on the jig saw got in the way. Yeah a saws all might have worked if you weren't doing cabinet grade work hell a chain saw might have got it cut but I was looking for something a bit easier to control. I have had it 3 whole days and have ran up against 3 problems where this strange little tool was THE answer. This cabinet had crown molding making it difficult to remove the 1 1/2" I need to cut away for this installation. I used the circular saw where I could and then connected the dots with the vibrating saw. It is kinda strange to use you tend to want to shove it and when you do it quits cutting. You have to almost cradle it in your palm and let the saw do the work.
Here is the trash picked china hutch top I modified to nest tight to the wall of the caboose. I had to remove 1 1/2" to let in the 2x6 you see in the picture. The little saw made it so much easier.
