Thanks,I tried and failed to get jigsaw blades to fit in the bits holder after filing them down [to thin and not enough grip for a saw action].
I am trying to find an awl to fit on the outside,I have one from a sack but there isn’t enough metal to drill a hole.
First time I’ve had a house and therefore a shed,the bench and vice I added make life easier [i really enjoy doing small jobs].
I cut down some rubber vice grips to fit then started on the jig saw blades.
