    That makes a lot of sense for a surgeon's saw given the antibiotic properties of Silver.

    The elves have been busy while I was at work today (because being in the shed on a work day would be naughty), but it looks like they left the handle rub down and wax, along with the assembly to me. Watch this space.



    Hopefully I will get some time in the shed tomorrow when the three coats of shellac will have fully cured. So said the elves on the note they left me.

    Are these “Elves” available ever were, or is this just a Tasmania thingy,
    If there available in Victoria I have a few handles that need some Elves love,

    Cheers Matt.

    Matt, I'm sure they are all around. The tricky bit is to attract them to your workshop though.

    I have found that leaving half finished shoes lying around is like honey to a bear. Once they've moved in, you can reduce the shoe parts and they will busy themselves with other projects.

    Oh, if you do this though, NEVER leave a cup of tea on the bench unattended. It won't taste quite the same when you return.

    You are lucky. My elves leave nothing but a huge mess.

    They could be poltergeists though....

    Maatsuyker #11976-4324 is now done.

    Let's start at the beginning.

    Don’t ask about the name. That’s how it came.

    I was quite excited about this saw. At 350mm (14″) long it was earmarked to fill the “large tenon saw” spot of my pending set of back saws. As an additional bonus, the handle appeared solid and the teeth were all accounted for, which boded well for a relatively simply restoration.

    This is what it looked like when it arrived. A 14″ Disston rip cut back saw dated between 1896 and 1917 as best as I can tell.

    119.1-1024x768.jpg 119.2-1024x768.jpg

    I had had already been soaked the saw plate and back in a vinegar bath, given a cursory clean, sprayed with a light coat of WD40, and wrapped away in tissue paper. This journey therefore started with a rust free plate and back.

    My first course of action was a run through the grits of W&D on both the plate and the back. I topped out at 1200. There is a significant amount of pitting, which has next to no bearing on its usability, and as all my saws are users, I wasn’t going to try and clear the pitting up. Then on to re-installing the back. I wonder if there is a way to lubricate the plate or back to aide the installation process. As it was, it’s a slow process with lots of hammering against blocks of wood to get it back on. The plate pulled nice and straight, and only minor adjustment was required to work out a little belly in the mid section (if only this were the case for people too).

    Then onto sharpening. Once I commenced the jointing exercise, I discovered that the teeth weren’t quite as uniform as I had assumed, so a fairly deep jointing was needed to get all but one tooth to adhere to my expectations of order and conformity. That errant tooth will just have to emerge over the course of several sharpenings, and endure the judgement of its well formed brethren in the interim.

    Whilst not having to file in new teeth from scratch was a welcome change, I have come to be rather fond of a rake angle of about 4º. As such, I did end up re-shaping the teeth a little as part of the process.

    The saw plate was finished up with a setting of the teeth. Again I used the smallest setting. However about half was along the first side, I wondered if I could get an even smaller set by rotating the depth disk just a fraction more, which I did. At this point those who do a bit of saw doctoring will be shaking their heads and calling me an unlearned gentleman. I had considered potential negative consequences, but, well, you know, nothing ventured nothing gained.

    Then only the handle. Augh! One of the joys of using hand tools more and more is that I am required to breath dust less and less. Not so when sanding down years of grime from the handle. I did use the random orbital sander on the sides which I can hook up to the dust extraction, but the rest required copious amounts of hand sanding from 80 grit up to 400. Once done, I gave it three coats of shellac and left overnight to cure.

    20191206_160953-1024x768.jpg

    Because I wasn’t quite ready to call it a day at this point, I moved on to the saw nuts and medallion.

    A long “bristled” brass wheel brush on the drill press for the medallion, followed by a visit to the buffing wheel for all the hardware brought them up to a lovely shine.

    Day 2

    It was with a sense of excitement and anticipation that I popped into the workshop the next day so get the saw finished. First up I rubbed down the handle with some 0000 steel wool, then gave the handle a wax and buff.

    Next up it was fitted to the saw plate, and some minor adjustments to the back to fit neatly into the handle recess. It all went together very nicely ahd the nuts tightened up well to create a firm bond between handle and plate.

    Onto the test cuts. Whilst no doubt desirable in other circumstances, the cuts were graceful arcs curving down and to the left. Every cut. No matter the preventative action I tried, graceful arc after graceful arc. It was at this point which I accepted my earlier tooth setting experiment had indeed been an error of judgement. Fortunately I recalled that about eight months ago Matt mentioning running a diamond plate over newly set teeth to work out irregularities when I was diagnosing my first effort at sharpening. I did this, and low and behold, it worked. I was not getting straight cuts. Perhaps that piece of advice having proven useful has balanced the scales against his naming of this saw.

    Here is the completed saw in all of its splendour.

    And a family shot of the restored Maatsuyker collection so far.

    And finally, just in case you think I didn’t learn my lesson regarding changing the set half way through aligning the teeth … For want of a straight cut I needed a diamond plate to run down the side. Eagerness picked up the dirty DMT and got metal dust on my fingers. Lack of attention didn’t notice the fine steel particles being ground into the freshly waxed handle on further test cuts. I cried a little bit on the inside, then buffed it out as best I could. All because I tried to be tricky.

    A very good rebuild and excellent write up. The Elves will be proud of you. These really are good examples of how a really rough looking tools can be so well restored.

    The backs can be tapped on with a wooden mallet placing the heel at the toe and tapping in the longitudinal direction. A small amount of grease applied to the plate assists this process. Any surplus that squeezes out can be easily wiped clean after. Sliding the back on in the longitudinal direction gives a small amount of tension to the blade and minimises the buckle that can appear.

    Thanks Paul, this is the technique I use. But... the longer the back the increased friction you end up with and the tougher it gets the further on it advances. I will try a bit of grease on the next one!

    Lance; I wouldn't be too quick to blame the setting tool.

    Stewie

    Andy used to participate on these Forums under the name "Brital," but quite a while back he had to "rationalise" his time and limit Forum participation. That video is one of the best all round tutorials on hand saws.

    Thanks for reminding us.

    Good one, Lance.

    As Stewie says, it's quite possible to put excess set on one side of a saw even when you don't mess with the anvil setting; it's all about developing absolute consistency. That mostly means placing the set so the plunger meets each tooth at the same point. It's terribly easy to change the position you aim for a little bit when you flip over to set the opposite side, and that can have quite an effect on the degree of set. In theory, as log as you hit each tooth at the same point, & squeeze until the plunger stops, you ought to put a consistent bend on each tooth, but (especially on a big saw), your muscles tire a bit when you don't set saws every day, and your consistency can fall off a bit from that cause, too. I'm finding my ageing arm muscles tire more quickly, so it's something I've become conscious of, particularly if I try to set 3 or 4 saws in a row.

    However, I strongly suspect altering the anvil after the first side had much to do with making the circle cutter. Nothing like a hard lesson to help you remember that it's very naughty to change conditions halfway through any experiment!......

    Thanks Ian. Oddly enough, one of the other reasons for adjusting the “dial” was so that I could line an indent on the dial up with the tooth point to try and improve the consistency. I hadn’t however considered the fatiguing factor. One would think a software engineer would have fingers of steel, tapping away all day on a keyboard. But alas, that’s not quite the case. I’ll be certain to pay extra attention next time to ensure I’m exerting full force all the way.

    You've encapsulated the problem in a few words there Lance. You're a software engineer, but saws are hardware. Me, I'm just getting older with failing muscles.
