Nice job Ducky. I tried something like that with a Dewalt jig saw and it didn’t like hanging upside down and the parts that hold in the blade got lose. 

The Dewalt service and repair place is 75 miles round from me. Instead of getting it fixed I bought a Ryoby. It’s green like the Fe$tool so there can’t be much difference. 

How far is the Fe$tool repair shop from you?
What is the depth of cut on your hanging upside down like a bat setup?
