The restoration of this saw filer was the most amount of work yet!

This tool is a saw filing and setting machine made by Black Diamond Saw & Machine Works of Natick, MA, U.S.A. sometime after 1911. The original patent from 1909 can be seen here: patents.google.com/patent/US942531

Unfortunately, the saw setting attachment has been lost, but I would love to find it one day.

This particular machine showed signed of been very well used and repaired in ways that suggest it was used in a production environment. I ended up needing to pour new babbitt bearings, machine new parts, repair old parts, replace fasteners, and completely change all the paint colours to get the tool back to a more original state.

I absolutely love saw filers and settings since they have some of the highest gizmocity of almost any tools their size. I will be saving this one for my personal collection.

I would like to thank Evapo-Rust for sponsoring this video.

    None of the other restoration channels have taught me about Japanning and Babbit, let alone make it themselves!

    I worked at a company back in the early 80's where every machine was an antique, and they poured Babbitt bearings fairly regularly. The machines all had oilers as well, and it was someone's job to keep the oilers filled. The machines were about 80 years old at the time and still worked very well, but they required a good deal of maintenance. They were very awesome to look at though with their pin-stripes and decorative castings 😊

    I'm always surprised at how complicated and robust such machines/tools were a century+ ago. And I'd like to hear about your process for keeping all of the parts organized and putting these things back together. That's the more impressive that the restorations.
  • @ptrkmr
    Ok these restorations I often see restore obsolete technology but this ones got my seal of nifty approval
  • @TizonaAmanthia
    Recasting Babbet Bearings is the kind of thing I really love seeing. all the shmucks that follow you can soak in vinegar, and wire brush. but doing the full treatment, and advanced repair things like that is why you remain on the top of the pile.

    Me, before the last twenty seconds: "Man, he's really a genius" Me, after the last twenty seconds: "... well, he's special"
  • @rirkc
    Man, that has got to be the most intensive, confusing yet satisfying reassembly I've seen yet. Amazing! Thanks so much.
  • @rickky2000
    I love that you always add humor into theses. They’re incredible to watch but even more so when you’re being your authentic goofy self. Thank you hand tool rescue! You’re my hero

    Просто шедевр!! Мужик, ты мега крутой!! Пересмотрел почти всё, что есть у тебя. Наслаждение для моих глаз! Когда из проржавевшего куска непонятно чего, новые инструменты появляются!
  • @Yackhammer75
    I don't even do restorations but I love to watch your videos. I especially love the attention to detail. Always trying your best to not only make it work but fixing old bad repairs and putting things back the way they were when it was made. From remaking knobs to trying for correct colors as original. Can't beat that kind of craftsmanship. Always inspires me to do the same on the projects i do work on. Keep the great work!
  • @HardestEli
    I make my wife watch your intro thoroughly, everytime.

    Very nicely done, complete with the gotcha humor and all. Kudos for pouring your own bearings, that is no kidding getting to be a lost art. As I see in the comments below, several people didn't even know what they are. I have a couple of old machines from around the same vintage that have them but thankfully they are still in excellent shape. Keep them lubricated liberally and they will last years and years. I actually saw some poured up close and personal on a 6 inch shaft once. Here's a pro tip, NEVER just toss a big hunk of cold babbit into a pot of already melted material. It will explode. Some idiot did that on the pour I just mentioned and there were six of us out on the ladder boom for the cutting wheel on an old dredge hanging out in the middle of a river with no place to go when he did that. Hot molten metal went everywhere.

    I like how this creator does his restorations. He allows the pieces age to still show. There is no need for perfect and shiney and sterile for every piece. Mirror finishes, powder coating, no casing marks removed except those that are dangerous. Yep, I can watch this creators work every day! The first time I watched a video of his I was hooked and spent half the night watching. Thanks!
  • @Pede711
    Recasting babbit-bearings. Didn´t even know such thing existed, and now I know the principles of renewing them. Amazing work
  • @joshredding9588
    that kind of ingenuity built America...nice restoration sir!
  • @rickcrooker2407
    Have read about Babbitt bearings in books that were set back in the "good old days" but this is the first I've ever seen them and seen them replaced. Most interesting. Also got a good chuckle with the unexpected, reverse face plant on the cabinet sandblaster. Thank you for doing what you do so well.
  • @coledremsa6323
    Your channel has to be my favorite tool restoration channel. 50% due to the intros and 50% because of the restoration done. Love it! Keep em coming.
  • I love this video, I love old machines, I think they are much better than new ones! 😁👏
  • I have learned more watching this channel than I did in Highschool and I carried an A-B average.
