Hi, I have a Record 050C, combination plane, and found it very tricky to use. I suspect the main problem was/is the relatively low quality of the timber I was trying to use. That and the grain always seeming to be running in the wrong direction. The supplied cutters are all either plough or beading. This seriously limits what mouldings can be achieved.
I have only rarely needed mouldings, to match existing, and have normally resorted to a scratch stock, with perhaps multiple passes with different blades. Scratch stocks are nothing more, in the very basic form, than a shaped scraping blade mounted in some form of handle which provides fences of sorts. The blades can be made quite readily from dis-used hard point saw blades.
If you are looking for a method of producing the same mouldings regularly then I am sure someone could make you a moulding plane to suit. But be aware some of the problems I mentioned earlier will present themselves when using a moulding plane. One beauty of a scratch stock is that it can be used in either direction.
