Antique Hand Cranked Hammer Drill - Restoration

It was in spring this year when I picked up this beaten up antique hand cranked hammer drill. My friend has found it on the steel waste together with the german „Weltrekord“ ratchet screwdriver. The condition of the drill was super bad. It was very corroded, had a lot of missing screws, the handle was in very bad condition and the crank was bent so much you couldn't even make a full turn. That's all said, it was the perfect item for a new restoration video.
At first I thought this should be a quick and easy project, but one problem after the other became visible and it turned out to be a real challenge. There was the big dent in the left side of the case. Usually you can't bend casted parts, but with a bit of heat and careful pressure on the arbor press I was able to remove it a bit. It also worked to get rid of the warping with some heat. For the finish of the housing I wanted to have an antique cast aluminium look. I thought it would look very cool if I could tumbler these parts after sandblasting. I ended up building a huge rotary tumbler from scratch and it worked very well (video link below).
Another big issue was the tool holder and the drill bit, as they were both completly rusted. Big thanks to @HandToolRescue at this point for helping me out with the dimensions on these two parts by disassembling and measuring his own hammer drill. After a bit of search on eBay I found a set of original Rawlplug drill bits. After they arrived I was able to measure the shaft and the taper of the drill to then turn a new tool holder. It all worked out very well and yes, the drill only holds with the taper ;-)
Before I even started this project I just had one question in mind „How am I going to replace the messed up handle cover?“. My first idea was to wrap it in nice black leather like steering wheels are made. That would definitely work, but that's something I've never done before so I was quite sceptical. Then the idea of a heat shrink tube came up. That would be a very easy solution, but heat shrink tubes don't have any structuires to it and it wouldn't quite fit the the rest of the tool. Thanks to the research of my Patreons and channel members, they have found very special heat shrink tubes that have a structure in it. I really liked it as it almost looked exactly the same like the original handle.
After all it was a very intense and time consuming project. I've done so many hours of research on this one and I had to learn new skills. I'm very happy how it turned out.

I hope you like my work and the video.

I payed a lot of attention on the lighting when filming this video and also the quality of the sound to create an ASMR style video.

If you have any questions about the process, machines i'm using or other stuff, just ask me in the comments. I read them all and i try to reply as soon as possible.

Sorry for my bad english, it's not my language. I try my best to improve my technical english.

Thank you for watching :-)

    I gotta admit, there’s always an anxiety filled moment at the end when I feel like you’re not going to test it out and you never disappoint
  • @androkon6920
    When you sanded down that rivet, and blued it, and it was completely flush, I felt that deep down. I really did
  • @MonkTorius
    I have tried to watch other restoration channels that come up in my recommended, and it's just not the same. The sounds and enjoyment from your videos are unparalleled in my brain. Definitely, my favorite restoration type channel.
  • @ilikeknafs9563
    The most impressive part to me is when he is like “I make a new one” and he makes it look so easy and gets the part exactly perfect . That alone is so mind blowing how he gets all the dimensions/proportions and measurements so precise with such ease (often freehand) . This guy isn’t human
  • @carbon2593
    The sheer excitement one gets from "I Make A New One....", this man is the single greatest therapist to ever live
  • There's no other restoration channel on YouTube that I've found that's as good as yours. You set the bar sir.
  • @JessicaAVoigt
    So cool to see you using some things that you restored in the past to help restore new items! Amazing restoration as always!
  • @user-qx8jf7re8i
    На три вещи можно бесконечно смотреть в жизни - Как течет вода, как горит огонь и как "моя механика" реставрирует казалось бы "мертвые" вещи! Великолепная работа!
  • brother, i live in Innsbruck (Austria), i work for an elderly care home, i think in USA they call it “nursing home”, in this case 99.9% are WW2 vets, i have been showing them you work everybsingle Sunday for the last Year, they all are crazy about it, most of them used to work as Metallmeister on the which means they do know what it means to work with metal for the Führer, however, average age 90-105, they do love you work. In their name, Danke schön from the greatest Evropa generation ever- 👍🏻🍺
  • I have a feeling this guy once slit his finger on a particularly sharp edge, then proceeded to remove all sharp edges from that point on.
  • @howizee
    Love watching the tools and equipment that have been restored being used in other projects.
  • @JorryGT
    You are an absolute craftsman and I LOVE watching your videos! There is nothing more satisfying than seeing how much life you bring back into these items, it's unbelievable 👏
  • @evilotis01
    the part at 9:05 where you make the rivet just... disappear into the plate is truly one of the most beautiful things i have ever seen
  • @ShamankingZuty
    It's always so satisfying to see you use tools you previously fixed. It's like watching a TV show and saying "I remember that character!"
  • @user-bo3wv4hh6y
    Потрясающая работа! Сколько сил было вложено! Приятно было смотреть
  • May no one ever despise you as this man despises sharp edges. Great content!
  • @pedrofelck
    I love one aspect of your videos beyond the repairs: your editing. That's part of what makes them so enjoyable, the way you show the progression of time without just accelerating the video is wonderful.
  • @MoultrieGeek
    I'm so spoiled by My Mechanics that I simply can't watch any other "restoration" channel. What this man does is a beautiful blend of art and science, all the rest are mere pretenders.
  • @user-jv5it8gq8s
    Как же мне нравится смотреть когда восстанавливают старую вещь.И от куда вы только знаете что к чему подходит.ВЫ огромный молодец и руки золотые.Похожая вещь была у моего отца в его огромном столе.Походу он любил собирать старинные инструменты.👍
