Couple months ago I made this little fixture to clamp on to my 12" backsaw, think I used it once or twice. But yesterday it proved indispensable cutting a bunch of slots (future dog holes) for my new bench top. I must have seen a picture of something like this somewhere but did a little searching and couldn't find anything. Not sure what it's called.
Just some scrapes and maybe a dollar at the hardware store. Tapered the ends of the inside, so when screwing it together it closes in the center first.

Do you guys use something like this?
