A decade ago (!), while road testing the new Veritas chisels (then only O1 was available), I built a box partly to house them and partly to demonstrate them in use ...

This coming weekend I shall be part of a dovetailing workshop, and decided that it was time to build a new box for these chisels. These are the chisels I use in demonstrations, such as wood shows.

For one thing, the number has grown from 5 to 7 chisels (I had made a 1/8" from a spare pre-production 1/4" - this was before this size was available from Veritas - as well as a 3/8" fishtail chisel. At some stage Veritas will be producing their own version. I do not have any details).

A second factor was that I thought the existing box was a little OTT, and wanted something more subtle, and less in-your-face. The fact is that the joinery in the new box is far more demanding than the first box, but only those experienced might recognise this.

It has been a month or more since I have had any regular time in the workshop. My practice has been crazy busy, but now I have a few weeks leave. In particular, I had some time free yesterday and today. This has been therapeutic and fun. I hope others get something from the details here ....

The light wood is Jacaranda (in both boxes), which is the last harvested from a tree on our property several years ago. It is softish, not so nice to saw and dovetail, but planes beautifully. The darker wood is Makore. Another wonderful wood to work with.

The construction of the box is mainly mitred through dovetails - all lower corners and the end upper corners. This makes it easier to plough through grooves for the base and top. The mitred corners are also, in my view, far more aesthetic, lending a balanced presentation from the top.

The sides are held in a sticking board when ploughing grooves with the Small Plow.

The rebates were planed with a skew block plane and then fine tuned with a rebate plane. This is the main use I find for rebate planes ...

And from the upper side ...

The finger depression was carved with chisels ...

Inside the box, the chisels are held very firmly with a combination of rare earth magnets and individualised spaces for each chisel ..

The O1 Veritas chisels differ from the PM-V11 chisels in that their ferrules are square at the front, while the PM-V11 are curved (I do have a set of both, with the PM used in the workshop) ...

This square section enables the design to butt them fore- and aft. They cannot move about. Plus the magnets hold them firmly as well.

Derek, can you talk a little bit about what glues work for you to hold down rare earth magnets, do you use maybe a washer underneath the magnets, that sort of thing please?

Hi Scott

I simply drilled a mortice/hole for each magnet, and then epoxied them in.

Beautiful work Derek. I think you've inspired me to do something similar.

If I could offer one small suggestion when you make your next box 10 yrs from now: you can also recess the magnets from the other side so they're not visible. The holding force goes down but probably sufficient if you keep the wood between the chisel and magnet thin.

One could also use a thin piece of veneer to cover the magnets.

Scott,
I use Loctite Super Glue Professional Liquid. Available at the usual Big Boxes. A little dab’ll do you. Works great.

Derek,

As always, exquisite. I am a BIG fan of the original, OTT or not, it speaks to me.

Always appreciate you sharing with us. Best, Patrick

I guess I will chip in. I have some rare earth magnets and some chisels. Don't bother using fish glue to hold the magnets down. I had 33% glue failure within 24 hours and 50% failure rate (6/12) within 48 hours. Of course 2 of the 12 rascals held in with fish glue are still hanging on two weeks later. I haven't tried PVA.

I have decided I don't like the magnets sticking proud of the wood substrate. The clacking sound drives me bananas and it supposed to be bad for the chrome coating on the magnets. Looks like Derek's are well recessed.

I am not enamored, honestly, of having magnetized chisels trying to make whoopie when I am not looking and have two or more of them loose on my benchtop. They can do all sorts of things that require remonstrating verses from Leviticus 18 be spoken over my tools when I am trying to get some work done.

For my second attempt I used JBWeld 5 minute (2 part) epoxy for the gluing down of the magnets, with zinc plated washers ( quarter inch nominal, star type "shakeproof" lockwashers, OD 0.500 inches, homestore, and responsive to the magnets) under the magnets. But I didn't redrill my dang holes deep enough, so half of the magnets are still proud. After the fish glue failure I drilled my available holes to 0.200 inches, half of them finished recessed and half proud. The good news is I am about 7 days in with no glue failure on the JBWeld epoxy, and a homestore zinc plated lock washer (underneath) does dramatically increase the holding power of the magnets for cheap.

I was using a weak magnetic strip to hold my chisels on a tray. They wobbled about a little bit, so I had to open and close that drawer with some restraint to keep the chisels from swinging about like clock pendulums, but the chisels didn't couple (or orgy) like rabbits when loose on the benchtop.

On the one hand chisel handles have a fairly uniform width, so popping in a certain number of rare earth magnets ( I think mine are spaced 1.5 or 1.25 inches) or using a strip of weaker magnetic tape doesn't change the number of chisels that can fit in a fixed width drawer.

If I decide to stick with the rare earth magnets I shall drill from below (as Greg Funk also pointed out already), and then epoxy in a magnet, a bit more epoxy, a lock washer, and then flip the board over when I glue it down to the drawer bottom. There will just be a wee on center hole showing from above where the tip of the Forstner bit poked through while I was drilling. A rare earth magnet (mine are from Lee Valley) with a lock washer under it _should_ reach through 1/8 to 1/16 of wood no problem, my half inch LN mortise chisel can spin like a clock hand over a recessed 1/2 inch magnet, with washer below. I guess I would check brown or purple heartwood of poplar before going all out, but with white sapwood of poplar, white maple, etcetera I would not expect significant loss of magnet power.

Were I to do site work, like Derek teaching classes, having a chisel box that is both Frenched and magnetized makes perfect sense. He can open the lid, see the slots are full, know none of his tools grew legs and go home, without worrying about the chisels rattling about in his vehicle on the drive. My father in law was an airliner mechanic, same idea, no tools left behind in the turbofan. Since I only do shop work, I prefer the flexibility of not Frenching, just magnet with no size specific cutouts; so whatever chisels I am using a lot can be easier to reach at the front right and the ones (among my favorite 12) not getting used a lot right now can drift to the rear left. The second dozen are in a different toolbox a few steps away, and since nothing is Frenched they can migrate on my whim.

Site work, on site teaching, is simply not on my bucket list (mostly because I am not very good at joinery and often grumpy); but if it comes up I will once again type the letters I-N into my browser for a refresher.

Beautiful box Derek, as usual.

Patrick, today I purchased some imitation Kaizen foam (cheap and not as good), to try out this idea ....

Stanley knife for scoring, Starrett 12"/300mm combo square, Starrett mini double square, Starrett small dividers, Shinwa sliding bevel, Veritas cutting gauges (mini and full size), dovetail gauges (5:1 and 7:1), and a driver holder with three driver bits and an awl.

Hi Derek, The box looks great. I am curious about the finger depression, looks like you might have defined the edge with a forstner bit and then carved the depression, was it done with bench chisels or a gouge? I really like it and would like to try it myself.

That is basically how I did it. Drilled a smidgeon with a forstner, just to set the perimeter, Then a little out of the centre (shy of depth). Finally excavated with gouges: out channel to shape, and in channel to finish.

The hollow was created in the same way as Alan Peters demos here … just smaller http://www.woodcentral.com/webbbs/smileys/smile.gif

The first box, fully fitted, comes over as more refined. The hinged lid is the issue when in use. When you get to 7 chisels the lid would become very awkward, hence the change in design.

The circular magnets add a very modern look to the box, the floating chisel ends less refined. It is a lovely box make no mistake and that is part of the problem! If it was a pure utility simple boxwood construction with magnets it would be ‘acceptably’ modern :).

Like you Derek I have a hard time building utility, imagining I’m going to live long enough to enjoy the luxury or at least someone else will! Unlike you, my luxury is usually limited to veneer!

It is true a washer below the magnet acts as a keeper and increases the holding power and life of the magnet. My appearance suggestion is to mix epoxy with ‘bronze’ powder, it’s really copper powder. The result is dull gold or aged bronze, rather refined. If enough is added to each magnet to flow over and just fill the void around each magnet you get the more classic look of gorgeous wood and bronze. Two or more layers of blue tape with the right size hole would help restrain the epoxy.

I use this a lot, repairing ‘oops’ on my bench. Filling worm holes on spalted wormy maple, gives subtle flecks of gold. I use the West epoxy system which is truly transparent. Just a thought.

Derek, I have been going through ways to hide the ploughed groove for the panels. Watched a video (Rob Cosman) on four ways to hide. Cutting the last pin at 45 deg was not one of them. Thank You!

Scott, Rob Cosman was asked to demonstrate a mitred through dovetail. He declined, saying that he had never made one. I understand and partly accept this. It is not a joint to teach beginners.

My ranking for dovetails is, hardest to easiest: mitred through dovetails (as the joinery is 3D); through dovetails (as the joinery is 2D); and half-blind (as the joinery is 1D). Secret mitred dovetails are a notch up from half blind as it is the mitre that is relevant. The dovetails are never seen.

Beautiful execution of what for many could have just been a utility object. I always enjoy your work and the way you elevate things to a higher level. Thanks for sharing the upgrade.

Thanks Derek, I could use some carving chisels;). Just ordered a few; unfortunately they are on backorder. Once I give it a try I will let you know.

One thing I’ve seen on your site that I would love to learn is your curved dovetails. They looked fantastic. I’ve never seen them anywhere else
