- How I built the Reciprocating Rack & Pinion mechanism. Prototype model, layout, timing, a failed motor application, modification of a Roomba drive motor using a lathe turned drum attachment.
Usually the pinion is stationary and the double rack section moves back and forth and would be connect at one end or at both ends like a connection rod. In the case of my model a connecting rod could be connected to the pinion axle. Either way, the mechanism delivers straight-line push and pull.

My Dad spent most if his life repairing fishing tackle & I would watch him tear down reels, make springs, install parts salvaged from old broken scrap reels, etc. This dual rack & pinion slide assembly was in the Orvis reels for the up & down even winding motion. U had seen him taking the stuff apart, cleaning and greasing it and putting it back together & watch it work just by pushing the spool up & down! But up until I watched your video with the wooden model...it never really made since in my head...& I have been a tool designer for over 40 years! Now I have another aspect to use, thanks to your teachings! THANK YOU!!!
I'm not sure what motivates you to make these little gadgets, but I'm glad you do it. I learn something new every time I watch one of your videos. You do a great job of explaining the processes as you go through them, without wasting a lot of words, and the video footage high quality, too.
Thank you! Glad to hear you are enjoying my videos. Please subscribe.
Sir...you are a true hands on engineer...it is amazing that you could design tool and build all the components by yourself and that too with such a finish...cheers
A very elaborate and cool demonstration of rack and pinion mechanics!
This is just the solution to an issue we face in a project my son and I are working on. Thank you for sharing.
Wonderful build, explanation and demonstration, thank you!
Great piece of work Ron, but moreover very generous of you to share.
thanks for sharing the idea, this is what I need for my project. God bless you.
Thanks for taking the time to make and share this video!
10/10 would brush teeth with that.
+Edgar Pineda Finally someone who thinks not pervertedly! Damn these minds are rare these days.
I should mention I'm very favourably impressed with Ronalds work and ability to think. Anytime I'm tempted to vain pride concerning my work and capability, a visit to this part of You-Tube quickly upsets impending delusions--and for that, I'm grateful.
Amazing... I was involved in an invention that is uncannily similar to yours, back in the late 1980s... The inventor, a friend of mine, sunk something like 100 to 200 grand in it, mostly in patent related fees (I strongly advised against it - I thought he should imply manufacture the device and sell it himself, but he wouldn't listen and ended up practically broke). But to come back to the thing, he spent lots of time at the machine shop trying a design, modifying it, coming back to it... He'd be on the road constantly ;-) Boy how things change with the evolution of technology! Now one could probably design it all on a freeware CAD and build it directly on a 3D printer...
unbelivable,amazing,i think it is very good.
...Can't understand why there're 469 thumbs-down on this video.
In one word: envy. The video is awesome =)
Pedro Sacramento I totally agree.
Muy Bueno el video....gracias

Christopher Polheim was an swedish engineer during erarly 1700. He mad I think over 40 different motions like this in wooden modells. All from quite simple to more advanced. They was the base for a Engineering Shool in stockholm founded by the king. Before this sweden was not anything near technology or mechanic. We knew hot to make very good steel already then but that was it. But from this point with this wooden models and all the students learned mechanical motion everything started out that later became that our small country became famous for making very clever engineering and also able to manufacture them.
Excellent craftsmanship. Enjoyed the video.
Cool. Neat project. I enjoyed it. Thanks for sharing.
Parabens pelo trabalho amigo, ficou muito bom mesmo.
Great Explanation and Prototype.. Can be effectively used for a Scroll Saw..
great work and explanation
omg, your expertise is as fascinating as this mechanism
Ron I've used the glue with paper to hold items together in the past. I've now switched to the 3M pull free picture mounting technology to do this in my shop. It is faster, removes cleanly , and holds to metals as well as wood and other porous surfaces. I've even used it to hold a metal straight edge to a rough wood board to straighten an edge on the table saw.
For the last 5 years or so, I have been searching the internet looking for an electric rocking chaise lounge. I've found a gizmo to rock a hammock (side to side) and I've seen the rocking bed but I can't find a chaise lounge that will rock. It seems unreal that it's not out there because it would help overactive kids, people with depression and anxiety and the eldery as well. I have seen plenty of patents but no-one seems to have come up with something. I was really hoping for my 60th b'day, I'd be able to have one but I guess not. I had a fairly rare aggressive cancer that I fought and finished treatment at the end of August last year. It has a 85 to 95% chance of returning within 2 years and this has been one of the things on my bucket list.
Ronald, I loved your video and the fact that you told us what didn't work as well as what did. Best of luck to you sir.
Nancy, if you're still with us, at 66, they exist now. I did a simple search for them on Google, and found quite a few, some indoor, some outdoors.
I hope you're still with the living so you can pick one up.
very nicely done, and thought ! Thank you mostly for sharing the glued paper trick, very very smart one ! I will use ity with cigarette paper in by job as I am a jeweller. Thanks again. Frederic
I can already see Matthias using this in one of his AWESOME machine ideas!... Nice job Ron!
Epic stuff, I love engineering.
beautiful work!
Ése sistema es muy usado en maquinas tortilladoras, lavadoras industriales, maquinas qué fabrican vallas metálicas, limpia parabrisas etc. etc. Muy educativo el vídeo, felicidades 👌
This is very inspiring and as Mr Spock would say; "fascinating" !
Thanks for posting !
fajne, lubię oglądać realizacje podobnych pomysłów
Thanks for sharing Ronald! Love your vids :))
Marvelous!! Nice work!!
Thank you to share a very nice piece of engineering. cheers...
seeing it "clunk-clunk-clunk" at the end brought me joy
Beautiful job, buddy. I am now subscribed to your channel.
This is awesome. I created a oscillating movement with three geare and motor but this is cool.
An interesting design, thanks for sharing it :D
Quite Amazing at what you do
Very nice Ron!
Brilliant! Thx for the vid!
nice
Thank you for sharing your knowledge and skills so that others like myself can learn and incorporate the information into such things as automata art!
very well done.....both narrative and building of item........
That was fascinating. Thanks
good stuff as usual mr walters.
very nice job, nice hand skills. We must not let these skills die
I love the paper and glue trick!
Very cool!...Now I know more, thank you.
Beautiful!
Very interesting, Ronald. As a retired printer the mechanism you've designed is similar to the flatbed movement of the 2 revolution Miehle press. The main difference being that the gearwheel did not have the cut-out and moved laterally and engaged geared racks offset to one another. Buffers took the strain as the heavy type bed reached its end motion. I've tried to find a drawing but no luck. Best wishes.
Great fun to watch - thanks
thank you for sharing
very cool, ron
After completing my education in electronics I realized I wished I'd studied ME instead! Also, wtf is wrong with air-heads who gave this video thumbs down! This is a fantastic video. Thank you for sharing your knowledge, much appreciated. If I may suggest, you might consider follow up sequels to this showing practical examples/applications.
The grass isn't always greener. As an ME, i sometimes wish I chose EE.
That's pretty genius to be honest, I can see it being quite useful
I don't know what this is but I like it! You've earned yourself a sub!
That first motor you've shown is not a bad quality motor. It is just not intended for your application.
You mean it's made for a system without much resistance?
I guess some motor need to turn at high velocity to produce a significant contribution.
Using the same gear difference shown on the second motor we may actually see it work properly.
Yep!
And it's got a gear adapter to translate the axis towards the edge; you can surely dissasemble that mounting to get the original bare-metal motor (with the axis at the centre)
Whoa that's awesome!
Thanks for the idea!
Thanks for watching. Please subscribe!
That is what keeps this channel going.

@@RonaldWalters2010 of course sir
It's a bit over five years since this video was created, and as I was watching I was thinking how 3D printing has made prototypes so much easier. But the romance of working with wood is special.
Ahhh… an Aussie. I have lived and worked in Australia (dating back to 1973) and have many Australian friends. Thanks for watching… and for your comments. Please subscribe! Ron
awesome video
Very well made Video!
So smart !!
awesome
Awesome dude!
Namaste Mastermind Walters! Clever idea, ´cause you saved (recyled) material . Sometimes it´s so simple to save nature !
Live Long And Prosper \\\//
Really nice.
Damn clever!
Cool as hell!
had fun watching this thanks
gostei de ver este belo trabalho
Ron that is slick as cat shit on a humid day! Great Stuff!!!
Very nice! I like that!
great job!
your idea is nice! I like it.
Cool!! Nice Work!!
Thank you so much for making this video. I've been scratching my head trying to work out how to make a large scale levelwind for essentially a kontiki reel. Although mine is actually towed out by a large kite and skyhook rather than a kontiki. Anyway I've converted a self propelled lawn mower into a large, petrol powered reel and just needed a way to get the fishing line back on the reel evenly. I'll use your idea but gring teeth off a bike gear and tack weld lengths of the chain to the inside of a steel box. Maybe mount that on a heavy duty draw runner.
Google the French fishing reel - "Mitchel 300 images" - look around for photos of it taken apart. It's been around a long time.
Ronald Walters that is cool. Mine will be more like a bait caster reel and about 50X bigger. My kite tows 25 baited hooks on a 360lb fishing line a mile out to sea. I've built a trolly mounted reel with a 4HP briggs and Stratton motor to wind it in (usually gets 7 or 8 big fish and the occasional shark) Just need to make a levelwind. It's a common fishing method in New Zealand but outlawed in most other countries. To be honest I've enjoyed building the reel more than the fishing.
Молодец мужик. Тарелку от CD-ROM а изобрёл деревянную. Как же мы все раньше жили?
Awesome!! thank you!!!
May be useful for some kinds of saw tools. Like it!
Very cool.
nice work thanks
This is the same mechanism that made the old Mitchel 300 spinning reel mechanism work . In this case the gear case moved and the gear stayed fixed and when rotating , causing the spool to go in and out from a pin in the back side of the gear case connected to the spool shaft -- meanwhile, another gear on the crank caused the spool to turn . This made for a pretty simple and very smooth retrieve mechanism which was really advanced for fishing reels over a half century ago .
I love racks. Subscribed!
now thats clever. bravo
Very good.Fernando from Buenos Aires....
if I ever get into black smithing I hope I remember this so I can make my bike powered billow set I been thinking about!
That's so cool.
1:51 that thrusting action!
Saltwater Reef Aquarium Hobbyists, myself having been one for a number of years, have long searched / invented / fabricated creative ways to create "random" water flow within their aquariums. All sorts of contraptions are coming to market to ATTEMPT to mimic the random water currents found on our natural coral reefs. I could see a longer, water-resistant version of this installed so that it runs the length of the back of an aquarium with a powerhead/pump attached.
This is a version of the gears that make the agitator in a washing machine reciprocate.
The first motor you tried is called a synchronous motor. It is primarily designed to have a low torque extremely stable speed. Like in clocks and timers etc.
Very near to the "magic lever" used by SEIKO for autowind in his watches. Nice.
Very clever!
Very good. Now if you made one that was 20' long, that would be totally awesome!
I needed a scrollsaw, this makes the design much easier, and saves me $200
Wow, life changer ;)
One more tooth would limit the stress of impact at the end of travel.
No dear ... At last , impact will only come on 1 tooth only however you may put as many teeths but impact will only come on 1 teeth
Very cool, thanks for sharing +Ronald Walters
Brilliant.
