Here’s what Chris was talking about

the other day, Chris Schwarz wrote about a new double-screw vise he’s been making for Jennie Alexander. In that post, Chris mentioned that JA & I used these devices in ways different from what we’re now used to seeing. http://blog.lostartpress.com/2015/01/07/a-prototype-double-screw-vise/

Chris made quite a splash with these things (think Moxon vise…) but it’s funny how different craftsmen come at at thing like this. Schwarz, Alexander & I all read the same passages in Moxon’s book, and Randle Holme’s about these bench fittings. 

But what we made depended on what we wanted to do. JA & I were interested in frame & panel joinery. Mortise & tenon; narrow framing parts; panels that might be a maximum of 10″ wide. So our double-bench screws were small compared to what Chris came up with for his work that featured lots of dovetailing of large carcasses. 

Just the other day I was using one JA made to plow grooves in a chest frame. Here a short, narrow muntin. This gives you an idea of the scale of my bench screw = and this is my large one! The muntin might be 15″ long. I have it clamped in the double screw, which is held down by the holdfast. Then the muntin is jammed up against the bench hook.

Here is another version, even smaller. This is the one I made when Alexander made that above. Here I’m splitting tenon cheeks on a joint stool apron. (this exact photo might be in the joint stool book – I know the tool/device is…(http://lostartpress.com/collections/books/products/make-a-joint-stool-from-a-tree )

I think of these like their descendants, the hand-screw. They come in many sizes, for many functions.

One more. This setup is for mortising the chest rail. It’s probably four feet long. Hold fast secures the rail in place, but its 1″ thickness can wobble a little. So I stabilize it by clamping the double screw to its nether end.

JA has now adapted this joiner’s device for ladderback chairmaking. So we’ll see that surface some day..but while it was on my mind, I wanted to give you some ideas of how we used them in joiner’s work. 

(as usual lately, when I sit down to write a post, I see I’ve written it before – here’s tonight’s post only from 3 years ago!  https://pfollansbee.wordpress.com/2011/12/30/you-say-moxon-vise-i-say-double-screw/
