Pedal-powered mulcher: field test and progress report
zhlédnutí 906Před 2 lety
Filmed in August last year, this video shows a functional but only hand-cranked version of the mulcher, still in construction, and is interspersed with clips of early steps and of progress since August. This filmlet distills about 30h of footage from almost 1000 hours of work (with much trying and erring...). Thanks to everyone who supports this project and still listens to me while I blather o...

See other videos on this project: czcams.com/video/SOBmVeKn9os/video.html czcams.com/video/oyB913cHy4w/video.html czcams.com/video/EiPHCqMMpkU/video.html I've been wanting to build this since at least 2016. I've spent more time on it since fall 2019 and have finally reached this first stage. I've never built a cutting/processing mechanism before, only added pedal drives to existing devices, so ...
Pedal-powering a household electric wood chipper
zhlédnutí 395Před 4 lety
Bought a wood chipper (120 V ac). Figured out how to connect it to my pedal-powered generator (0-150 V dc); had to bypass the chipper circuit board ("Soft Startup") and drive the motor directly. I'll probably set up a proper switch for a pedal-powered DC ("PPDC"?) option. As expected, the ride was a steep hill. I see a peloton on the horizon.
Pedal-powered generator on upside-down bike: it blows!

A speechless show of an amusing, slightly useful, mostly informative contraption. Includes a recumbent seat from bike parts, a gear-multiplier, details of a bike cog fitted to a motor spindle, and a DC motor replacing an AC induction motor in a small appliance.
Installing a replacement rail on a fancy bike saddle
zhlédnutí 64KPřed 5 lety
Another mostly silent video. A friend asked me if this fancy saddle could be salvaged, since its rail was broken. I said I'd try. Found a rail from a scrapped saddle that matched, from my community bike shop. Used metal bits I've accumulated at home; bought nothing. The process was quite fumbly; yay, VSDC Video Editor. There are a few more fancy saddles to restore; it'll take mere minutes, now ...
Bicycle for an armless person
zhlédnutí 765Před 5 lety
On-the-fly torso tilt control, two-wheeled back-pedal braking, 8 speeds (internal), and chin controls, make it possible and pleasant for a person with no arms to ride a bike. Based on memories of a previous model made many years ago, which got stolen a few years back. If you built the previous model for Tracy and you're seeing this, please contact me; I'd love to ask you about it! Enjoy the vid...
Fabricating Shimano "Deerhead" gear-shifter clamps on a mini-lathe
zhlédnutí 265Před 5 lety
Making missing and hard-to-get clamps to attach friction shifters for vintage Shimano M-700 derailleurs (Deore XT "Deerhead") using a mini-lathe. There's sawing, turning, boring, and tapping! A mostly silent skip through the many, but not all, small steps: 25 hours (more?) summarized in 9 minutes. A very labor-expensive pair of clamps, but it was worth it 'cause I learned lots, I have them here...

How to remove rail?
I love the concept and have been searching for this kind of technology for a while. Respectfully, do you sell any version of the pedal powered muncher (either single or multi-rider?
Hi. Thanks for your interest. Unfortunately, this is only a prototype and is not for sale. But if anyone around you wants to build something like this for you, I'm happy to share what I know. Cheers.
❤❤❤
Good job..from surabaya indonesia
Well done
Really nice work! One suggestion: in the old days the hand powered straw choppers / chaff cutters ishad a big and heavy iron wheel (or maybe even two of these) so the kinetic energy/momentum stored in it when rotating made the cutting much easier.
Good point. The bicycle wheel here serves this purpose, though it would work better if heavier. Still, most people riding this machine complain that it is too easy to pedal! The gearing is quite low. I have looked into chaff cutters but have found that none of them seem to be used for sunflower stalks, a significant garden remainder. Thanks for your comment.
@@janprzysiezniak7563 make a cement slurry and pump the tire up with it. let it cure with the wheel laying horizontally so it doesn't settle to one spot causing severe imbalance. Cheers from Beaver County.
finally there is a video on this method..Actually I just want to forget it..👍🙏
Amazing work man this is beautiful peace
Thank you so much, I am working on building my own recumbent trike, and I was looking for ideas to make or build my own seat. I’m glad I found your channel because that’s exactly how I’m going to make mine, thank you so much for sharing 👏👏👏👏👏.
Szukałem tego filmu od dawna. Wielki dzięki
“Let me just grab the dirtiest gloves I own before working on this expensive seat.” Proceeds to breathe like Jason Vorhees through the entire video.
Hah. Good one about the gloves. But you must have had your volume way up high; maybe you like heavy breathing?
I wish you were closer I would send you mine to fix. I will be scared to do it.
JP you are nothing less than an inspiration. Thank you for doing inspiring stuff. Thank you, even more, for sharing the journey.
Так вот оно что!!!!!!!!!
Tq, smart👍
Job done! ✌️ thanks
Much better then the one I hade on board.
Brilliant.
Formidable, yo quiero sacarlo para tapizarlo, es posible? Asi con la misma operacion, saludos
I haven't tried removing the rail, but I guess you have to hold down the saddle while you do this.
Would it not be easier, cheaper and safer to just buy a good pair of pruning cutters to do this job?
Ha, ha... Not if you're chopping through BUSHELS of sunflower, tomato, potato, cabbage, bean (etc.) stalks at a sitting. Check out my video about the pedal drive. Still, I do sometimes question the complexifications I put myself through. Thanks for the reminder.
Fun, funny and entertaining as well as truly inventive!!
Pretty amazing chopper! Careful with the fingers!
It looks much worse when viewed end-on...But I am duly warned. Thanks!
Great job Jan!
Wowww🤯🤯
this is amazing. well done
Thanks, Robin!
What weight capacity does it support?
Good question. I haven't done any testing. I assume the fresh rail, even if slightly bent by this procedure, should hold as much weight as it was designed for. Assuming, also, that the plastic rail sockets aren't damage by this.
Genial!!! ... thaks for this video Maestro ...
Jan this is incredible! So nice to see you today, thanks for letting me know about this project, I'll be following along!
Thanks, Leila!
sweet
Jan it was a pleasure to see your video and especially listen to your narration. Your tinkering and its product are beautiful.
What a great idea! Loved the interaction and humor with the gardeners. I hope you keep working on it and post updates.
Way to work in an Archimedes' reference! I have the same issue, and I can't find a rail on sale. So, I have to get a salvage one ?
Yup, with the same distance nose to rail tip.

Love it! I have a WTB SST98 with a broken Ti rail, but I refuse to give up.
Awesome Jan! I really like the edits to show the pieces under construction during the main sequence; very cool! Looking forward to seeing it in action under pedal power.
Great job Jan. You always inspire and impress me.
Serwus, gdzie się znajduje Twój warsztat? :)

Hi Jan, great video! A few questions: what size bolts did you use? What size holes did you drill in the small metal bars? How thick are the small metal bars? Thanks in advance.
Hi Math Guy! The bolts are 1/2" (13mm) in diameter, around 6" (15-16 cm) long. The holes in the plates are 1/2". The small plates fitting near the nose of the saddle are 3/16" (5 mm) thick. The larger ones are 1/4" (6-7mm) and 5/16" (8mm) thick, whatever I had around... Thanks for asking. Jan
@@janprzysiezniak7563 Thank you!
nice cycle recycling
Question: I want to use the ti rails from my old Titec Berserkr saddle on a new DMR saddle. If the over all length looks the same within a few millimeters, can this be done ? I’ll just have to wait and see, if I get the DMR. But video was very helpful. Always wondered how you would get rails in and out.
On second thought, this old Titec Berserkr K-Ti is still going after 4 bikes and 20 years...mostly commuting miles. But now it’s a trail bike. Oh, I ride it home on the street. I recovered in leather 10 years ago, or longer, and still looks new. I should just cover it in camo fabric like the DMR. Could even create a channel. A bit of 1/8” foam and I’ll have a nice sofa saddle...PS: I saw a NOS Berserkr on eBay for $160...
That's one thing I didn't address in the video: sizing. And what you suggest is exactly how I proceeded, i.e. matching parts within a few millimeters should work.
Hi Jan, cool video as always! Been a long time since we played Irish tunes together; fun times. I hope you're doing well!
Hmmmm? Brian?
@@janprzysiezniak7563 Good to hear from you! Crazy times eh?
@@green_dog8960 Hey! I wrote you at your work. Dja get it? Let's email.
U R D 🐐!!! 💪💪💪
Thank you very much for this demonstration! Simple and brilliant. Would be great to know though, how the manufactures do this in their factories …
Hi Christian, To answer your question, see this, specifically at 1:48 czcams.com/video/qdWzZaDUJqc/video.html Cheers. Jan
@@janprzysiezniak7563 So they basically slam the plastic piece over the titanium rail at the end. They dont have to slid the TItanium rail in. Guess its not made with repair in mind.
@@ark_knight Yup. Bending plastic is easier than bending metal, and if it doesn't break or warp, it mostly returns to its original shape.
@@janprzysiezniak7563 8:42 czcams.com/video/J4n8qkwIElY/video.html is another example.
Great video👍🏻 and fantastic method of putting the rail in place! Do you know where you can get replacement seat rails from as I’ve been searching for ages and can’t seem to find any!
Good question. I work at a community bike shop, we discard damaged saddles. I found one with an intact rail the same length and width as the saddle I wanted to fix and did a switch. I doubt it's something you can buy, so ask a bike shop for scrapped saddles?
@@janprzysiezniak7563 that’s great, thank you for the advice 👍🏻
Clever! Thanks for sharing, Jan.
Well don't try this lol, oh you can't post pics here. I tried washers in front and 2 door-lock latch/strike plates from home Depot, 1/2" boly in front and 5/8 bolt in rear, 7" long. It all bent to crap. Need thick steel
Do you think I could just use washers and shave the sides if they hit the plastic?
