Making a new 'tote' for a #4
A bit over a year ago (already) I tidied up an old type 11 #4.
It had its original rosewood woodwork, which I would have kept, but a bad break across the lower grip of the tote (the most common site of breakage I have seen) made a seamless repair nigh-on impossible & as I wanted this to become my new “user” #4, I decided to just re-wood it. I chose some Solomon Island ‘ebony’ (Xanthostemon melanoxylon), which comes up vaguely similar to rosewood (well, it might fool an old bloke without his glasses on if he looks quickly), but it polishes nicely & is the equal of rosewood for tactile qualities.
Fast forward to this week & the old plane has firmly established itself as my go-to #4 – it’s no better performer than the well-fettled post-WW2 English #4 that I’ve been using for the last 25 years or so, but I just like its rugged looks & it neatly matches my type 11 #5 ½. However, there was one aspect I wasn’t entirely happy with. In the post linked to, I showed how the tote sits closer to the thumbwheel in this early model – there’s barely enough room for my fingers to not rub against it. The problem is exacerbated by my using a thicker (Veritas) blade, and the cam of the adjuster barely reaches through enough to engage the edge of its slot in the chip-breaker. This created 3 turns of backlash, which means the thumbwheel is much further back as normal setting than it needs to be. You can see the more cramped space compared to my former #4 lined up behind it: Attachment 513859
Having a day this week when I had nothing better to do, I thought I would see if I could improve matters. The most obvious fix would be to build up the cam on the adjuster yoke, but I don’t have a torch suitable for fine brazing, so I put that off for another day. The tote I made last year has developed a lot of fine cracks (a flaw of SIE, it seems to be a difficult wood to dry without internal checking), so I thought the easy way to get a relatively quick fix was to re-make the tote and bring the stud hole as far forward as I safely could, gaining maybe 2 or 3mm more finger room.
I’ve made many totes over the years and have it down to a pretty simple task except for one thing – getting that darned stud-hole at the exact angle & in the exact right place. It’s a relatively simple task if you are re-wooding a late model, where the tote sits on a raised, flat platform Attachment 513858
But up ‘til at least the mid fifties, the stud goes into a raised boss. This complicates setting out a new tote in two ways: a) the stud is frequently quite a loose fit in the sole, & b) the castings must have been set up for drilling by eye, no two seem to be in exactly the same position relative to the centre-line of the boss (which being a casting varies a bit as well). So the best I can do to get some sort of fix on things is use a small bevel gauge and set it to the centre of the up & down ‘slop’ in the stud, then eyeball where the line is relative to the side profile of the boss.

The safe way to proceed is to make a mock-up from a piece of scrap to make sure you’ve read it all correctly. Attachment 513856
I didn’t, quite, and it needed a bit of adjustment of the boss-hole for the tote to sit down
[ hint: get the stud/boss fitting first, then when it looks like it is sitting down nicely, a gentle tap or two over that little dimple under the toe will accurately mark its position – I’ve tried setting it out by measuring it innumerable times but it almost always ends up a fraction out, requiring the hole to be enlarged or extended, which is somewhat defeating its purpose as it does its best job of preventing twisting of the tote if it’s a neat fit ]
Once you have the mock-up sitting nicely in place, the ‘real thing’ usually goes smoothly, as long as you take consummate care in setting up the blank & drilling. I always drill from both ends – start with a 6mm bit for the stud hole, then drill the 7/16” counter-bore for the nut & the 15-16mm recess for the boss. Drilling the boss hole involves turning the base of the tote to horizontal & carefully aligning it to the centre-line you set out for it (the crucial bit of which has been removed by the 6mm bit). My first attempt went awry because I probably forced the drill & didn’t withdraw often enough to clean the lands & the stud-hole was off, preventing the tote from sitting flat on the sole. Forcing a twist bit is a sure recipe for wander in woods like She-oak with those hard rays to throw the bit off. But try # 2 was very close to perfect (which was just as well, it was the very last piece of suitable she-oak I had left!).Attachment 513855
That’s the tricky part done, the rest of the job is pretty straightforward. This is my choice of weaponry for tote-making; my 10" turning saw, a couple of ‘modellers’ rasps’ a #49 rasp, cloth-backed paper & some 0000 steel wool. And an invaluable little tool – a tapered scraper made from a scrap of .032mm saw-plate: Attachment 513854
I first smooth & square the saw cuts, then ‘finger-gauge’ pencil lines around the centre, & at the same ‘setting’ on the faces. I then draw lines at half the distance between centre & edge & again on the faces. Attachment 513852Attachment 513853
I begin shaping by rounding the toe & tip of the horn Attachment 513851
Then rasp to the first set of lines all round Attachment 513850
