More on crochets (sideboard hooks)

Dean makes some very good points in commenting on my earlier post and Bob Rozaieski agrees.  What they say about the function of the crochet makes sense to me.  The crochet allows you to edge plane without setting holdfasts and is therefore somewhat quicker.  For wide workpieces where the holdfasts at the bottom might be insufficient, the crochet holds it securely at the top.   Of course, Dean's vise has these characteristics as well and that was Nicholson's plan to begin with.

The crochet I made is definitely not shaped correctly.  If you go into Google Images and search for "Roubo workbenches" you will see numerous examples of better ones with longer, shallower tapers that will clearly hold the workpiece more securely.  Curiously, if you look at Roubo's plate here, for example, you'll see that his doesn't have a shallow taper.

Update:  I have to admit that Dean, Bob and Adam are right.  I made a "sideboard hook" that matches the look of the Nicholson bench to my eye.  It's also somewhat wider than I usually see as I want to accommodate 8/4 material.  As I've written, I enjoy experimentation.  I'll likely make at least one more.  Although the angle is only 45 degrees it seems to work fine and, in any case, is more angled than Roubo's.  I continue to puzzle over why his is shaped the way it is.  I can only surmise that he thinks this is enough of an angle to hold the piece against the bench, and maybe it is.  Also shown in the picture below is my bench dog.  :)


  1. To be honest Andy, personally I think a person is better off just adding a twin screw instead of a crochet. I think I’ve used my crochet on my roubo twice in the past six months. I found my crochet is very finicky, and a pain to use. I use the vise every day, and with it attached to the apron you can also securely hold your work edge planing. I just think the twin screw has more benefits.
