You might think the E-Z Mark butt gauge should be featured in a Sir-Mix-Alot video, but it’s much more useful than that. Its real world application is for laying out hinge locations so they can be mortised into the door frame or door.

Just line it up to any door frame or door itself and give it a good whack with a hammer. The score will line things up perfectly for the hinge and you get a pro-looking install out of it.

Grady’s Hardware has the E-Z Mark 4″ Butt Gauge for $5.20, so if you like big butt-joints and can not lie, this is the place to find one.

    This is a tool that I believe time has passed by. These were once made in at least 4 sizes to fit 3, 3-1/2, 4 and 4-1/2 inch square-cornered hinges. I think that both Stanley and Adjustable Clamp made versions. General tools made an adjustable marking gauge that was a bit slower to use – but could also be used to scribe lines for reveals. In all cases they were used to mark the location of hinges on a slab door – and the hinge mortise (butt) was chiseled out with a mallet and a Butt chisel. The idea of the tool was to speed up the process for installing multiple hinges. Nowadays – if you want to speed up the process – you either buy pre-hung doors (where the work is done in a jamb shop) our use one of several router templates and a router with a mortising bit to accomplish the same thing. We try to steer our clients to the pre-hung door option – as a way to save cost. But if they want a certain look (special doors – or Baldwin Brass hinges as an example) we resort to our router jigs. We have an old long Porter Cable that sets up for 3 hinges at once – and an even older Stanley jig that is no longer made (I think that Bosch has one patterned after the Stanley) that we use for 4-hinge doors. For cases where it’s a real special installation with non-standard hinge placement – we use a HingeMate template – but that adds time to the job and cost. Routers, of course cut round-cornered mortises – so if the client doesn’t like this look – a PC corner chisel will square things up.

    While pre-hung doors are usually ordered pre-bored for locksets/passage sets – slab doors need more work. We like our lockset boring jig – made by Classic Engineering – which offers different options for different backsets and non-standard diameters. We also get a few clients who want to match (or use) old mortised-in locksets – so then out comes our Porter Cable 513 mortising machine

    Gage? Guage? Gauge? Ack! Proper use of spelling defeats me again.
