A bit of an unusual way of making a hole for cables, as someone has already said a hole saw would have been the easiest way. If there was a reason for making the holes square/rectangular a jig saw would have been my initial tool of choice.Chuffchuff wrote: ↑Sun Jan 12, 2020 5:10 pm
The plunge cut is about 70 mm long, so with a gentle movement fore and aft makes the right size cut, repeat the three cuts, and minimum of cut with a keyhole saw to make good the corners, good to go for the next one,!
Those little plunge saws are quite good for things like cutting flooring boards on the joist but only marginally better than a jig saw when it comes to making long straight cuts. I think I would have saved myself £20 and gone for the Macalister table saw which would be a far more versatile tool especially if you do not consider your woodworking skills up to scratch.
