- I do these videos for free, un-monetised. TH-cam now put ads on any video to give themselves revenue, whether the content creator wants it or not. We don’t get anything. Sorry for the interruption.
This covers how to make a tapered clockmaker's broach, from scratch, using music wire, including making a jig.
Make a tool to make a tool...been stuck in that loop for 5 years now, and loving it!
As a blacksmith, making a tool to make a tool is everyday.
This is a very clear explanation. I did some google-ing about broaches vs reamers. This scale of work is so much smaller. Thank you for posting. I taught math, it seems like a prior lifetime, so in class we'd occasionally play around with constructions using only compass and straightedge, in the shop I may make some shortcuts. It's always interesting to see how others work. Thanks again.
Glad you enjoyed it John :) And with your other post; blacksmithing certainly is a tools creation trade, making beautiful/functional items with the mind and the hands paramount. Cheers
Awesome video! Thank you for taking the time to share your knowledge!
Also, awesome knife; the stockman pattern is my absolute favorite and what I carry with me almost everywhere!
Glad you liked it Wilson. Cheers
Brilliant video thanks.
I carry one of those knives at all times, it was a present from an uncle 60years ago.
Thanks jonka1, glad it was useful.
Yes, the knife is a good one :)
Just discovered (a year later) that I replied to your comment with my wife's account! Must have been out somewhere and used the 'phone ; we only have one between us as we're always together :D
Thanks for another very informative video. I really enjoy these.
Glad I'm achieving my goal Phil :)
I really like the stick/paper idea :)
Glad it was useful Anthony :)
The reason the tip was fatter is because the file only went half its width past the end so less material was removed on each stroke.
HTH
very nice indeed.
Thank you kindly
Great vid! Been looking for Broach making info.
Glad to help Benny.
good work :)
That seems like a lot of work...
I’m sure a broach turned down to a taper from soft steel, hardened and one flat ground in would work just fine (that’s what the broaches from my Seitz jeweling tool look like
G'day Jonas, Watch and Clockmaker's broaches are different to jewelling reamers. I was making mine based on commercially produced ones I own. It would be faster using soft steel, but I don't have the set up yet to do case hardening; I could have annealed the music wire, and then re-hardened and tempered it after shaping, but I don't feel that my skill level with those processes is quite up to snuff yet. Cheers
Thanks for sharing this. I really appreciate. Such an clever and easy method.
I guess a starting material can be a drill bit as well rather than a steel wire?
G'day htc. Glad you liked the video. My only concern would be that drill bits are on the brittle side, and when they snap, they chip, and things get interesting for your eyes very quickly, and you can't anneal HSS drill rod. I speak from experience. I had a drill snap on me and a razor sharp fleck lodged in the border of eyelid between the eyelashes and the eyeball, in line with my pupil. I was squinting at the time. I resolved that day to never drill without safety goggles again.
The music wire I use is quite cheap. A 3 foot length, the diameter of the one I used in the video, would be around $4 Australian, and will make quite a few broaches, spade drills, balance staffs, and on and on and on :)
All the Best
Cheers.
Thanks for your reply@@theselectiveluddite. And thanks for warning about HSS chipping.
I got some old watchmaking tools on my hands. On is quite large and rusty broach. I'd like to restore it even I don't really need it as it is quite large. I'll definitively will give a try for the method you shared.
@@htchtc203 Nice. I also have quite a lot of antique watch and clockmaker's broaches, a fair proportion of which have dull edges. You can see this by rotating the broach under a light. A dull edge will reflect light between the facets, where as a sharp edge will not show up at all. I used the method in the video (but with a hardwood block with fine tapered grooves at one end and holding the broach in my fingers) to sharpen a bunch of super fine watchmaker's broaches (like the one I show early on), using a very fine diamond hone (only about 5 strokes per face) followed by a small piece of slate. I used the method of pressing down firmly with the hone/stone to keep the face being worked on level.
I'm sure there's some reason I'm wrong, since you seem to know what you're talking about, but isn't that a reamer rather than a broach? I thought a broach was a tool that (let's see . . .) removes metal with an action that is parallel to it's own axis. Make sense?
G'day BLenz, Yes, terminology between trades can get interesting; where a tool like this in another field would indeed be called a reamer, in Horology it's referred to as a broach, and the action of using it is called 'broaching': eg. "Broaching out a pivot hole".
I don't know why there's the difference, but all the Horology books I've got, dating back into the 1800's, refer to them by that term.
Are you into engineering?
All the Best
Also, @johndilsaver8409, at the bottom of the comments, mentions googling the difference between broach and reamer, and it seems to be a size thing. Cheers
wow you are by far the best on the subject as far as teaching goes, i just got into this as a hobby and so far made a few simple tools. you should consider adding amazon links for stuff like the wire, i for one will have to buy some soon to reproduce this. thank you for your efforts
Thanks Slow. Glad you liked the video. K&S Metals are available at a lot of retailers (if you're not in a hard lockdown area, though ordering on line is the other option). Here's K&S page showing sellers in the US), and if you scroll down the page it has the international dealers. www.ksmetals.com/deals
Cheers
yep ordered s few, the stores out here are useless.
Oh, that's a pity. All the Best with the new crazy hobby :)
Agree, these videos are pure gold.
@@juslitor Thanks very much :)
