....I do have a jigsaw that I don’t use much, so I’ll keep the inverted approach (great idea) for the next time I need to cut small parts. Mine is a barrel grip Bosch that doesn’t cut ....

Sorry it doesn't cut... but Pottzy will explain why!... it's a Bos¢h.

If you try the inverted jigsaw, take care to hold the piece down firm... not a big issue but catches you off guard initially.  That's the beauty of the jig... can use both hands.

If your first cut is too short... Take the second cut from the longer end... LBD
