Great information as usual. I'm so glad Rex Kreuger pointed his viewers over to you. I do have to comment on that absolutely beautiful brass and wood marking gauge sitting on your bench. I'm sure I wouldn't be the only one to appreciate you taking a moment in a future video to give us all a closer look.

May well do...

[@tinkmarshino]

excellent.. Thanks for taking the time to tech folks.. I always have been a believer in passing on what one has learned to the youngers.. Carry on!

[@gjbmunc]

Glad to help

Thanks, you too!

'Registered' mortice chisel- often called a framing chisel, as it was used in timber frame construction; this required robust design for cutting large and deep mortices. Socket or tang- the advantage of the socket is the slow transition to the handle, leaving no ledge that can mar the wood at low angles. However it costs more- and has become a badge of 'upmarket' chisels. Many bevel chisels now have them, so use is no longer the distinction. Great detail on mortice cutting! Thanks.

You're welcome!

[@MCsCreations]

Thanks a lot, Graham! I definitely need to find some of those! 😃 Stay safe there with your family! 🖖😊

[@gjbmunc]

Thanks, you too!

Thanks for sharing. Great lesson.

[@gjbmunc]

My pleasure!

After watching this I just ordered two carpenter mortise chisels an 8mm and a 14mm. I need to cut a few good mortises for my bench build. Thanks for the lesson.

[@gjbmunc]

You're very welcome!

[@trep53]

@@gjbmunc Your welcome sir. I have just completed chopping 4 mortises that are 1.25”x5”x2” depth and they came out square and snug. These are for the short and long stretches connecting to the legs of my work bench build. I really enjoyed that. Now, on to the through mortises for the legs wedged tenons to connect to the bench top.

[@dubtownman9508]

Excellent tutorial sir.

[@gjbmunc]

Many thanks

You're welcome.

I got your book when it first came out. (You were in Woodstock at the time, and I met you in person a few years later). Happy to see you on KZbin now. Years ago, I bought some English made Footprint "Registered Mortising Chisels" and they are quite different from yours, and look more like what you describe as a firmer chisel. Unfortunately, they don't appear to be made any more. They were recommended in Fine Woodworking at the time, probably in the 1980s. I'd send a photo but there does not appear to be a way to add one in a comment.

[@gjbmunc]

Different manufacturers often confuse things by trying to seem unique.

[@davidstewart1153]

Mortise chisels are my favorite type. I look for opportunities to chop mortises!

[@gjbmunc]

Have fun!

[@sawdustmaker9631]

Wonderful video. I didn’t know that there was a difference in mortise chisels. Good to know.

[@gjbmunc]

Glad it was helpful!

[@dekphoto]

I’m wondering why the sash chisels are so long. They seem excessively long for the job they do. But I have no experience and I’m eager to learn. Excellent lesson! You cleared up much of my confusion about chisel types.

[@gjbmunc]

They're the right length for most sash mortises.

[@stevewilliams7852]

thank you,

[@gjbmunc]

You are welcome!

[@halorail]

Thanks

[@gjbmunc]

Welcome

[@roman_le]

I have quite old nice Marples sash mortising chisel and it has tongue not socket.

[@gjbmunc]

Yes, there's always something different!

[@mattmcgrane8975]

Thanks Graham. You said the sides of mortise chisels are parallel. I thought they were a little wider on the back (flat side) of the chisel than they are on the bevel side to give a little relief. Can you clarify?

[@gjbmunc]

Maybe some are, but in general the sides should be parallel.

[@johnford7847]

The registered mortise chisels (which I've always called "pig stickers") have more of a curved "bevel" than bench chisels. Is that intentional? How do you sharpen the chisel so as to maintain the shape? Good video. Thank you for sharing.

[@gjbmunc]

I prefer a flat bevel, achieved either by hand on a flat stone, or by using a small bevel guide.

[@JBuck-cu7xd]

Would you not recommend the David Charlesworth ruler trick on a mortise chisel? Keep the back flat from tang to tip?

[@gjbmunc]

Indeed, keep the back flat from tang to tip.

[@dpmeyer4867]

Thanks
