If you have experience of 3 phase then you should be OK,
Depending on the size, (some of the listed shop front's can be of big sections) I used to saw mine out after doing the frame step down on the wobble saw, and as you know most 3 phase Wadkin type planers had a lower bearing housing under the telescopic sliding guard allowing 20mm shoulder to clear any rebate up to that depth overhand, which is what I did taking off the last couple of mil.
On the smaller Machinery stuff, As Wildman says just take a couple more passes on the spindle but don't forget to tack a packer at the fence bottom to stop any likely hood of tipping into the cut.
This also enables the safe fitting of the shaw guard.
