diy bike plans

A unique highway lowracer

A big wheel forkless lowracer

 

Even though my bike building has come to a bit of a halt this year, that doesn’t mean I’m not coming up with new ideas on a daily basis.  A few times a day, I like to find a quiet place to relax with a notebook and sketch up new project ideas. I have really missed my Marauder. I think it may be time to make another long wheelbase lowracer so I can get out once in awhile to feel that burn as I push both machine and engine to the limits. The terrain out here is not the same as the city, so my lowracer will need to have suspension to take me down the gravel road out to the highway. There isn’t much traffic on the paved highway around here and the ride would certainly be challenging thanks to hills and tight corners.

Another option is to transport it to a nice stretch of country road about 15 minutes from here where there is very little traffic and fairly smooth straight terrain. There are many cyclists using this stretch. I can just see myself eating roadies up once again as I slip under the wind and pass them one by one!

 

Some forkless bike examples

 

This time though, I want a very unique lowracer that has 700cc or 26 inch wheels on the front and back, a rear suspension, over seat steering, and no front forks. Yep, you read that right, no front forks! I have two designs for a forkless bike: one with a hinged triangle and the other with a wrap around frame that allows the front wheel to pivot much like the front wheels of a quad or tadpole trike.

Having no fork over the front wheel would mean that a larger wheel could be used without obstructing the pilot’s view. This will also smooth out the ride, so it would be a decent chassis for an aerodynamic fairing, allowing the rear suspension and long frame take up the bumps. Suspension is a must on a faired lowracer since these things can easily reach automobile speeds, making the smallest bump feel like a pothole. The forkless design and long wheelbase configuration also keep the front of the fairing low so that you can see the road ahead rather than having to peer around the body. This type of streamliner would not be all that great for pack racing on a track, but out on the open road, it would be a real blast!

 

A crazy pivot fork bike

 

The easiest forkless design is shown in my sketch and in these cool examples, where the hub pivots on a kingpin held in place by a single tube that wraps around the wheel, leaving space for the turn. I would run a connecting rod up to a control arm just behind the front wheel and then use dual cable steering to get around the curved tube so that there would be less flex in the system and tighter side tolerances for a fitting into a full fairing.

My other version involves a hinged triangle with the pivot very low behind the wheel to keep the tiller effect minimal. I have tried this in the past on this crazy ride called “Tour De Hell”, but the result was a bike that had serious bad attitude and took a lot of practice to ride smoothly.

Of course, having a short wheelbase and a huge amount of tiller, this bike steered like a front end loader, swinging from side to side and causing serious steering feedback. I think this system would work out on a long wheelbase recumbent if the pivot had more caster and was placed much lower to get it closer to the axle. I am not sure if I will actually try the pivot fork design since the other method would defiantly work as expected.

Perhaps this winter I may cut some tubing and lay out my new forkless highway lowracer. I always wanted to build a long wheelbase lowracer and then go all the way on a fiberglass fairing so I can get out and push the limits of what is considered possible under human power. I certainly won’t be heading to Battle Mountain to race with the big boys of speed, but I would certainly have fun smoking past road bikes doing 50 MPH on a faired lowracer down our country roads!

The time and space conundrum

Our basement before any renos were done

 

Time and space are those two things that have always managed to stump the world’s greatest thinkers, leaving us to the stark realization that we are but visitors on this rock, hurling through time and space at 66,000 miles an hour, tethered to a burning sphere by an invisible force in an unfathomable universe. This most of us take for granted, while refusing to believe these forces have any more effect on us than a butterfly beating its wings halfway around the world.

Yeah, I stole that quote from the X-Files and my mention of time and space here is under a different context, a more literal one; most of us need more free time and a larger space to work in! I am constantly trying to find more room for my junk (priceless parts collection) and at the same time store my creations, but there is never enough room, so often bikes are recycled for parts after a year or two. This constant shuffling of stuff then leads to my ever present lack of time, and often I just let things pile up and work around the mess since a full cleaning would take most of the day away.

After we moved into a single wide modular home, I knew that my indoor workspace would need more a lot more room; it was time for some basement renos. I have a fair collection of electronic bits for my work, so storage space and workbench room are very important. I decided to turn one end of the basement into a lab. It’s always fun to share photos of our workspaces, and since I have blogged about my old bike building shack down at the bottom of the hill, I thought it would be fun to show the space I am occupying as I write this now. The lab!

Anyone who has been in a modular home knows that they are 16 feet wide and long, really long! We decided to custom design the modular to sit on a full 9 foot basement so that we would double our space and end up with huge windows, making it seem less like a basement and more like a split level. The engineered trusses are great because all of the ductwork is out of the way, 9 feet about the floor level.

All of my electronics parts, robot bits, and good bike parts ended up in the basement, since we have very little outdoor storage space. The AZ parts orders are also packed down here on the brown table. There is a decent amount of space here, but I have not had much time to organize it or do any work. I did however, get to complete my new lab recently and am typing out at you from it right now.

Working with wood instead of steel

 

When you are a DIY type, it doesn’t matter what materials or tools you are using – you just measure three times, cut once and adapt along the way. Working with wood is certainly easier than steel, but doing a proper renovation does take a lot of research into code. Living in a Northern climate and having a 5 foot concrete wall with a 4 foot stud wall on top took some amount of planning in order to get the insulation done correctly. I had to build another 2×6 wall an inch ahead of the concrete wall and create an air barrier on the cold side then a vapor barrier on the warm side, keeping to an R24 insulation value.

Sure, I know what I am talking about now, but when I started, I didn’t know the deference between an air barrier and a moisture barrier. A moldy basement was not something I wanted, so I did my research. The secondary wall took out about a foot from the width of the room, but it still ended up being 14×16, and that was certainly enough room for me to work on my technical projects and plan writing.

My new lab partially completed

 

I continued the secondary wall up to the top, added a suspension ceiling, lights, lots of electrical and then put down a waterproof composite floor that looked like hardwood. I was quite happy with the final results, considering much of the things I did were new to me. I still need to finish building the cupboards and workbenches, but I am quite comfortable on the temporary tables and have plenty of room to store my stuff.

So, if time permits, I will once again expand my space, enjoying the rewards of DIY and learning new skills as I move along.  No doubt, if you are the type of person who would build a bike, you probably enjoy other DIY projects as well around the house and yard. DIY is a way of life!

Mutant Ninja Flowers and a Turtle

The AZ Yard Muncher

I know, it’s a bizarre name for a blog title, but when I started doing these morning musings, I decided to just write about the day before and try to keep it fun! As I had mentioned previously, this place has been like a rain forest lately, with rain almost every day for weeks on end. This onslaught of cloud juice has made bike building a real chore since I work outdoors mainly and have a completed bike that I need to take final photos and videos. Yesterday, the rain turned into more of a drizzle so I took this rare opportunity to get the mower out and get some of the yard cut. Now, this may not seem like much of a big deal, but we have to mow a three acre section of the yard. OK, that may also seem like no big deal but get this…I hand mow the thing!

No doubt you think I am insane for mowing three acres with a hand mower, but we have no place to store a ride mower, and this twice monthly mowing sure keeps my legs in good shape. Of course, a true garage hacker would NEVER EVER use an unmodified appliance, so of course I turned this otherwise tame mower into a beast of fury by modding the deck.

As you can see, the safety guard thingy that once held the bag has been replaced by a steel horn like thing that looks more like a snow thrower output horn. This little mower can now shred 3 foot grass, leaves, even small trees into mulch, tossing the shavings in the air a good 10 feet. Before I made this scary mod, the mower could barely cope with knee high grass and would jam up once every half hour. When I mow this yard, it takes me seven to eight hours if I walk non-stop, only stopping to refill the tank.

Mutant mow-proof wild flower

 
Since we have been having rain forest like rain lately, I have not been able to mow for more than two weeks, and these tall yellow glowers have taken up most of the yard. I don’t know what these things are, but I don’t think they are from this planet, and probably came here on an asteroid or some alien probe. In two weeks, these things grew over 2 feet tall and they can actually survive being run over by the mower. Yeah, no kidding, I mow them over two or three times and they just pop back up! I pulled one out by hand for inspection and they seem to have a stem made of green carbon fibre. At less than a quarter inch thick, the stem is so durable that it cannot be snapped by hand, and is as strong as wire. Anyone know what these things are? I wonder if dynamite will get rid of them?

Half-way through my mowing, a turtle decided to crawl up the hill through the tall grass for a visit. This little guy/gal was a bit annoyed by being picked up at first, but then relaxed and seemed to enjoy the free ride to the other side of the yard, away from the Yard Muncher. There are several creeks and ponds way back in the yard, but these are almost a mile away, so it must have really wanted to explore to make that kind of journey.

This cool dude came for a visit

With the way the weather is changing around here, I wouldn’t doubt that the next thing that comes wandering our of the pond will be a big ol’ gator.

Random thoughts, more rain!

Managed to snap a pic in between storms.

 

It’s official; we now live in the rain forest! And, when it’s not raining, the humidity hovers between 70 and 80 percent, so it might as well be. Oh well, here I am complaining about the rain when three months ago I was up to my waistline in snow. I guess that spring and fall really are the only good seasons for an outdoor bike hacker like me.

I did manage to get an hour on the Transporter Cargo Bike and added the cables, levers, and shifters. The first test run went well minus the fact that I had almost no air on the front tire. To complete the plan, I still have to get some photos and video of the bike being loaded with cargo, so it will be a game of waiting for the weather to cooperate.

Wow, a day that might not rain!

 

This week’s forecast is pretty much the same as the last two months with 40 to 60 percent chance of showers, which really means spitting rain every hour followed by intense rain for a few minutes and then 70 percent humidity until the next wave of rain. I don’t ever remember this much rain, and I am seeing plant life that looks like it belongs in the Amazon jungle around here.

New welding and grinding tutorials coming

 

In an effort to do something useful this year, we have decided to start making some highly detailed welding and grinding tutorials to replace the old ones on our website. These will be step-by-step video and photo tutorials from the very beginning that will show a noob what kind of welder and gear he or she might need, right up to controlling distortion. Since bike building seems nearly impossible out here this year, I plan to retro fit the non-leaky side of my shack with some backing boards and turn it into a video studio to make the new tutorials.

I will be purchasing a MIG welder as well for the tutorials since many are using one and will go through the process of both arc welding and MIG welding in great detail. Grinding tutorials will be the same in depth video and photo tutorials with hundreds of images lots of example videos, and text that explains everything one would ever need to know in order to jump head first into this great hobby.

A robot project from 2001

 

I like to dig through my old photo archives when I am doing my morning blog. Here is a real retro photo of one of my first large robot projects. If you can drag your gaze away from my super cool sideburns for a second, then you will see that I am riding on the robot, with an RF controller in my hand during a test run of the differentially steered transmission system. This robot was quite unstable and dangerous since it could reach speeds of 20 miles per hour and then flop over face first when something glitched in the motor drive processor!

But, the robot was fun to operate. I would sit indoors looking at a video link being transmitted from the head mounted camera and navigate (carefully) around the block, interacting with stunned bystanders using a text to speech processor that made the robot talk. I do miss building these things. Once I have an indoor workspace again, I have plans to build a 4×4 autonomous robot that will patrol our yard and keep that dumb bear off the property.

Well, I am going to head our and face the rainforest now. I have to find a way to cut the lawn in between drizzle as it is now knee high in most areas. Talk at ya later.
