A dedicated moulding plane makes a single moulding profile. These planes will make one profile at one angle, one location, and one orientation. Dedicated planes will have a fence and a depth stop. These two features make the plane apparently simple to use. The fence and depth stop also limit the plane by mandating the need of reference surfaces for each.
Hollows and rounds are versatile because they lack fences and depth stops. Hollows and rounds are attractive to woodworkers because they offer something which machinery can not: the idea of infinity. This idea of infinite possibilities is achievable due to the lack of an integral fence and depth stop.
The benefits in using a rabbet plane are similar to those of hollows and rounds: the lack of a fence and depth stop is advantageous because the lack of these two features means that there is no reliance upon either.
When making a single rabbet upon a corner of a board with a moving fillister or any fenced plane, both fence and depth stops may have predictable surfaces upon which to register…
or they may not. Depending upon dimensions, the face and the edge are not always accessible.
In these cases will you let the fence register against your sticking board? There may not be a better option.
When making two rabbets, as you will with most minimal moulding profiles, the reference surfaces for the fence and depth stop can become less clear and predictable: face and edge or face and previous rabbet? Just hope the rabbet doesn’t change dimension throughout the length because your stops depend upon uniformity.
Making three rabbets generally confiscates at least one of those reference surfaces from the plane.
What happens when you need to make ten rabbets next to each other for a slightly complicated moulding and you rely upon a fence or depth stop?
Or, what if your fence does not extend wide enough or your depth stop not adequately deep?
These last example aren’t good examples because you should be working on an angled surface here. So what do you do when working on an angled surface with a fenced plane?
I don’t know what to do in these instances because I don’t face such problems. I use a rabbet plane, which you can see me demonstrated here.
A rabbet plane is highly versatile tool that relies only upon the user. If you fight the plane to make accurate rabbets then you have a rabbet plane that is not accurately tuned and ought to be fought. Your issue is with the tool that you have and is not with the tool in principle.
There are, of course, many methods for making rabbets by hand. A block rabbet plane, jack rabbet plane, bench rabbet plane, shoulder plane, Stanley rebate plane, moving fillester plane, Combination plane and etc., etc., etc., can all be successfully used to execute our subject. If in use, however, you ever find yourself thinking “This is a tedious method to produce one rabbet” or “this is insane, there ought be a better way” then your conclusion shall be that it’s tediously insane with the tools you’ve been sold. The conclusion shall not be that it is tedious to produce by hand. You simply have the wrong tool.
In short, if you’re looking to add a single relief for drawer faces or window sash then, sure, go with any one of a number of fenced planes. Uniformity is ideal in these situations and your husband will be impressed with your gadgetry. Other than a rabbet plane,I can not recommend one option specifically for any task warranting this uniformity because I’d use a table saw 10 out of 10 times on these occasions.
Mouldings, however? Get a proper rabbet plane now or a rabbet plane after being discouraged by other options. Either way, you’re getting a rabbet plane.
(I’ve illustrated a moving fillister making rabbets above, any fenced plane will face similar problems once producing inside of the absolute edge.)
