Bicycle grinder for blacksmithing - how mine works

[@seudonak]

This is great. You can exercise and grind things at the same time!

[@zwigoma2]

Similar to sex. Ahahaha

[@crux85]

Came across one of your videos by accident, liked it a lot, kept watching your clips, i have an interest in bushcraft/woodcraft and i like making stuff, only now after watching a few of them i know what i find refreshing... No talk. No accents, no opinions, no distractions from the subject of the clip. It's like a breath of fresh air.

[@ni_r4970]

Rune thank you so much for sharing this (and the other videos). I love your bushcraft videos too, but I'm particularly impressed by these shop videos, it is clear that there is a lot of thinking and planning in doing them. Man you are SO CLEAR, when I'm just asking myself "mhh, and how it is framed/mounted/arranged?" the next shot is a direct and complete answer to my question. Of course your choice of not talking is a huge challenge, but man your are so much keeping up to it, creating instructional and gorgeous contents of super high quality. I'd like to encourage you with all my heart to continue with this work, you are simply great at it and lots of people enjoy it so much! Best regards.

[@ChristopherSalisburySalz]

Very cool! The thing I like most about it is that it doesn't require gas or electricity to run! It will keep you in shape and grind all in one.

[@thomasdehartii2941]

Just want to say thank you for making all of these videos. I love watching them because it always educational for me. I learn so much. Keep up all the amazing work you do.

[@samstone446]

You are truly a man of the earth. I enjoy your work so much and learn a lot from your calm patient way of doing things!

[@crazycoyote1738]

Rene, thanks for your creativity and clean videos. I tried shaping a round stone from a rock but cracked it multiple times. I came with the idea of making it from rich cement, concrete milk and sand, with metal mesh inside, to reinforce, and it came very solid. Center hole can be customized to any shaft needed. 🤙🏼

[@pops87fxr]

Great video, I just inherited a wheel, and now I see how I can make it work. Thanks for the video.

[@johnmutton799]

I am converting a 25 inch wet stone to peddle power. To sharpen my axes. Got two stones. Missed out on a Victorian cast iron stand, tradle power. Would nhave loved that.

[@Caddowolf]

Now I'm sure I could build my own after seeing every aspect and every angle of this one. Thanks!

[@tomray9031]

Rune, you are a genius!! Love the videos. Keep them coming. Love your workshop. A LOT of us are trying to make old time workshops. Will follow you until you get tire of making videos. Your friend from Texas.

[@jacobopstad5483]

I love the idea and the setup looks great! I might suggest cutting the sandpaper strips diagonally instead of straight across. That way they might be less likely to separate from the wheel.

[@robertfernando3668]

We have this kind of tradition in the Philippines fifty years ago or even further.. an actual bike that goes around each town offers knife sharpening service.

[@simonlaird5357]

Your very clever man&keeping great traditional skills alive

[@mulisha0351]

That slight hop in the wheel would drive me insane. I would have to true that wheel before i could use it. I like the design and implementation, well done

[@tutord]

Maybe add a fly wheel at the end of the rod. And incorporate a derailleur so achieve higher speeds

[@wdubduece8913]

I love the cinematic shots you always have. Don't get me wrong everything else you do is impressive but your great with a camera and I honestly think that's what has helped you with your videos. You're a talented man and keep up the fantastic work!

[@anonymouseuonymus]

Rune thanks again for showing us your tools and how to create them! Hope you can make a video sometime of your Forge!

[@BertramCraftAndWilderness]

Thanks - yes I will makes videos like this on all in the shop including the forge. I did post a few photos on instagram today from then I did make the forge... and a lot of photo from my old blacksmith shops as well - runebertramnielsen

[@anonymouseuonymus]

Awesome, definitely looking forward to the upcoming videos. I will follow you on Instagram and look out for the pictures. Thanks!

[@peterholmbushcraft590]

I have a dream to start my own blacksmithing. But I'm not home much. But looking at u making me feel like it more to do it and I love to bushcraft as well.

[@FelixImmler]

Thanks a lot for your wonderful videos. Your videos are a source of inspiration for me! Greetings from the pocket knife man

[@Dther99]

Smart! I'm looking to make a grinding wheel myself for my hand tool only workshop, and this is inspiring! Here's an idea- why not have an adjustable, smaller tensioning wheel that spins freely? That way, you can use a sanding belt held in place by tension instead of cutting and gluing emery cloth. Since the belt is continuous, this would eliminate the problem of the work catching the sandpaper, while also requiring less work to change and set up for different grits. I guess at this point it'd be a pedal belt sander rather than a grindwheel. Food for thought!

[@alextopor4038]

You should inclulde a ventilator to a chain line, so you can refresh the air in the room in the same time. Damnly fine job, simple and useful tool. Greetings from Belarus

[@TheAnonymousSword]

I was thinking on getting into biking and knifemaking. This is the perfect two birds one stone scenario for me.

[@Odino1962]

LOL

[@hillbillynick2000]

Very nice idea! I'll be making a "big wheel" grinder myself this year (once it warms up a bit) plan to cast the wheel with cement (not concrete) and use bicycle parts as you have. I hadn't thought of sewing up a stropping belt for it, thanks! I'll second the request for a video of your treadle hammer (plan on one of those also!)

[@tomlakeandriver7670]

Excellent moment, thank you for this passage simple and discreet without blah, blah, blah.

Thanks for posting I got a wheel the other day I like the idea of the bike frame " I am taking that idea :) "

[@mustafankamil1973]

Great video as always, but one word of advice always cut the sand paper at 45 degrees so you don't get any bumps ;)

[@BertramCraftAndWilderness]

Thanks. 45 don't work on this design - the steel will catch the point and off the emery cloth goes. 90 is a lot better on this design :)

[@Jimicramdhan]

[@ALSomthin]

You can buy rolls of abrasive thats made for autobody work that already has the sticky stuff on it in a variety of grits . Also a suggestion ; try making your seam or splice on an angle like a belt grinder belt. It resists things catching the edge of the spliced edge and it doesnt leave a bump or raised bulged place like a 90 degree seam does . It will stay together longer especally if you want to take it off and put it back on.

[@japeltoni]

[@punkbloater]

Love it, I guess you’ve thought of having a freewheel hub on it, would let it spin for some time making it a little easier on the legs, but maybe it’s not possible.

[@BertramCraftAndWilderness]

Thanks - it's possible but not to any use... the grinder will stop close to the second I stop bike it (grinding is a break). It's a lot simpler to make with out it and safer to use.

[@punkbloater]

Ah ok i see, thanks.

I think it would be really cool if you could add a suction based collection system on each of your grinding devices that was hooked up to whichever system you used, such as the pedal propelled system.

Those are not sandstone. They are commonly known as Arkansas stone they are made from Huronian Novoculite quarried from the earth. Sandstone wouldn't last 5 minutes against a piece of steel

Nicht schlecht, kann man immer wieder brauchen bei deinem Handwerk.Werden dir sicherlich noch einige nützliche Dinge von der Hand gehen.

[@janicekidson9704]

Hallo Malte, thank you for showing that grinding stone. I was curious about how you crafted that one. One particular thing I would like to see is the big hammer on the left, to find out how I can construct such a thing. I have a Feldesse from the early 20th century in good condition that was used to make horseshoes in the field. I want to head on from there once I have the proper time and make things a little bigger. And what blower do you use? Thank you for your work. The whole family watches your videos together.

[@BertramCraftAndWilderness]

Thanks - I will make videos like this one about all in the blacksmith shop... Including the treadle hammer (the big hammer) and the blower/forge. The blower is a common design... In my case is it made in Denmark for the danish army.... Hand cranked forge air blower.

[@leemcgann6470]

Do you find difficult to sand accurately while sanding? Would a treadle set up like an old sowing machine might also you to be steadier? I think it would be easy to set up with your rig. You could run the treadle from the other side of the wheel. & give you flexibility. Just a thought...

[@BertramCraftAndWilderness]

No - I can use this set up just fine, think it's ideal. I have used grinders like this for two years. So far could all visitors in the shop use the grinder just fine as well. It's pretty simple to use.

[@jakobpetrov1750]

Thank you for making this video

[@the.reel.mccoy.]

I assume you chose to use a bicycle instead of a foot pedal for speed. Do you have a video or could you make one showing the production of a pedal grinding wheel?

[@BertramCraftAndWilderness]

Thanks. Maybe - if I at somepoint need one.

[@manmodu5]

Can u add gears to this ? Might be more of a workout but will definitely achieve a higher cadence for the sanding belt.

Nice how you set up your sharpening wheel stone using the bicycle,and the easy changing of the sand belts and buffer ,my question his how often do you grease the bearings and what kind of grease you use .
