In hindsight I never gave the 'instant cash' bit a second thought, or the link either.
At least there's a 'report to moderator' button here....
Thanks Laszlo for your helpful reply.
Via dr google I've now learnt enough about rabbet planes to feel comfortble that I could cut tlapstitch rebates along the curved edges of the planks using a bullnose rabbet plane.
Without any experience using a router, I'm not inclined to attempt using a router for the job. However I'm curious. Doesthis require hand-guided router cutting up to a drawn line?
No idea what inspired Carlosford to add his post to this thread after the last one from 3-1/2 years ago, but my $.02 is that:
Edged tools put the onus on the user for how well they will perform. No volume of $$$ spent on high-end planes or chisels will buy tools that never need resharpening.
An edged tool with a dull cutting edge will yield no end of frustration and in fact may be downright dangerous.
There's no reason a hand plane bearing a competently sharpened iron won't perform its particular task in the hands of its user unless the user just doesn't understand how a plane is supposed to be employed; this isn't a conceit, rather it's a simple truth.
As for scarfing plywood, if a builder's not comfortable with using a plane for this, certainly a belt sander's an excellent alternative. Yet once again a measure of care is needed by its user if a proper scarf is to be achieved.
