this video just randomly popped up in my recommendeds, and i straight up BINGED all his old stuff. i have no idea why i didn't discover this channel sooner.
OMG, the CZcams algorithm must be reading my mind now. I am actually designing a joystick steering system, and this video appeared in my recommended video list.
Love to follow your build. Looks to me like you're almost building a human-powered California Commuter! I really love all the details. Keep up the good work!
Gonna be a badass reverse trike for sure. Pls make it safe. If you would role you need protection rollbar for your head also something to keep your arms inside the car. And good breaks. I can't wait for part 7 :D
The skid steering is great paul i have it on my greenspeed trike, it works great, plus i like the way you said it was easier to get in and out of thats a good thing lol. Have a great day. Choppersrule1
Quick release steering wheel is ohter option, to get in and out more easier. Or seat lifter. It is handy for better view in some traffic situation. In rear suspension, it is more simplier. Electrical shifter is position free. Basically first thing in planning is ergonomy. Vehicle is bad if you are in trouble to get in it.
Looks like the KPA is setup for good scrub and the steering is different but should work OK. Ride may be a bit rough with the straight axle and narrow tires but it will corner flat. I design reverse trikes so I find these home grown designs interesting
I'm taking most of my design from the plans of the California Commuter, with my trike being one foot wider front wheel spans and having twice the length on the swing arms. I made the swing arms longer so I could place my feet in between thru the floor for Flintstone reverse. I'm nearing a down hill coast test. I've decided not to go further until I'm satisfied that the steering and front suspension will shake out to my satisfaction.
If you're happy with the frame layout, now would be the time to weld it solid and have a friend do a low-speed tow so you can get a feel for the steering and suspension. Maybe do the breaks beforehand, though.
You read my mind Jarek! Right now I've got the rear brake, clutch and throttle all hooked up. Still waiting for disk brake parts. I'm about to weld up the frame but still a bit to do before I get to that point.
That’s cool I like that steering setup make it easy getting in and out. It’s opposite to my reverse trike which has a 1000cc motor not so fuel efficient!
Hey Daniel. I've spied on some of your videos of you revere trike BEAST! Opposite designs for sure, but we have similar building skills, except you can tig weld. So jealous....
@@paulwelkinsdiy they are different. I like your videos style too , are you getting it road legal? How fast do you think it will go ? Being so aerodynamic it would be pretty quick
With a tiller setup you might need a steering damper to help reduce bump kickback to your hands. I don't know the wall thickness of your front axle but the long leverage length from contact patch to shock might want to bend it at the shock mount.
It's not all that thick, so I'm thinking of welding on fore and aft support plates straddling the shock mounts. I was looking up what might work for a steering stabilizer but not sure what I'll go with. I need about 4" of travel yet only 13 or so inches long.
Unless you absolutely need a square a slot with rounded ends as much easier to create. You just cut two sides off of the rod instead of four (leaving the remaining material narrower than it would have been if you had been making a square) and then you can drill a hole in the top and bottom of the slot you're creating on the plate and then join the two holes with a Dremel and you're done. Of course since you were weldingit anyway a simple hole for the rod to go through probably would have been fine.
It does. I've taken the advise from my engineer friend Bob Stuart who suggested placing the king pin 2-1/2" forward of the tire patch and 1" inboard as well.
I don't know if you're interested in the e-bike side of things, but I'd like to see the velomobile community try to push what's technically possible with a 250 watt electric motor (the legal limit in most places without a licence) in these sit-down capsule setups. Maybe they could sustain traffic speeds?
Isn't the cage a bit small? In case of an accident the driver will be locked in tight possibly injured. Just a thought. I'm going to build one at least 36 inch wide where I sit.
hello ,Paul .Can I turn your stearing mechanism on the end of the axle,.... up side down ? If I want to use small wheels,... for instance scooter wheels ???? I mean the axle above ,... same corner ,...wheel axle low ?
ARG!!! Not sure Pipelonio. It's something you would have to try, and see if it works! That's often what I do. If it fails at least I know what NOT to do!
Do you have the clutch on the left hand-grip like a standard motorcycle? How will you clutch and shift at the same time with the shift lever down below on the left? Maybe you could rig up a cable operated foot shift?
@@paulwelkinsdiy well that answers my point... I also think sticking too motorcycle controls is better,,, half motorcycle and half car is asking for trouble..
Just a few pointers. Your steering set up lacks trail by the looks of it. This is quite a dangerous condition, worsened by the tiller steering system. A rack and pinion system lessens the load coming back to the driver. Those set ups get away with about 7 degrees of rake and the amount of trail that goes with that. Direct steering systems, like a motorcycle, have more. Like 25 degrees and upwards. I was pleased to see a fair amount of KPI. But, from what I can see, the scrub radius is large, further increasing the destabilizing forces in the steering system. This requires even more trail to get some positive dynamic stability.
I have been following you for a while. I've seen your other builds and I like this one the best. Are sure you want to go with that suspension set up? I think you are going to need to put on a kidney belt and make an appointment with your dentist for some new fillings after your first long ride.
I looks alot better with the steering levers,,but as you say you have all hand motorcycle controls ,,why did you not carry that idea though too the gear change,,, a foot gear change would mean a longer control arm but you would be carrying out the gear change with a spare /Unused limb. and as the change pattern will but sequential then no great problem... I also have issues with the front suspension...
Good observation. I already installed a side panel and yes, It's gonna be tight! Not what I wanted but IF I'm going to use the acrylic wind screen I have to keep to the width of the windscreen.
@@lucasvanhamburg4937 I know some of you laugh at the amount of steel going into this Beast, but I'm using what I can weld. I've never welded aluminum before, but know it takes skill. So far the trike looks like it will weigh in at around 300 pounds. I'm also planning on trimming off some of the steel rear section and replacing it with riveted aluminum.
@@paulwelkinsdiy alright thats cool! I have been experimenting with fiberglass and xps 300 foam sandwich and I think it would be a great material combination to use for a monoqocue design. I'm making a kayak right now but hopefully I'll find time to make my own hypermiler soon.
@@paulwelkinsdiy Btw, this is very similar to a project I had planned to do a few years back, but a disabling injury physically won’t allow me to do it. My vehicle was going to be an electric version of what you are building, but with an advanced suspension system (microcontrollers, gyros and electro-hydraulically controlled dampers) that would allow me to use it without pain due to said disability. I’m very interested in how yours turns out, so keep up the good work. And don’t forget to hit me up if you’re steering causes you issues.
Hey @@paulwelkinsdiy MY BAD!! I MESSED UP!! 😂😂🤪 I must have missed the the last few minutes of part 3 as I’d not seen the part on how you measured up your steering angles. 🤦🏼♂️ By the look of things, I’m pretty sure you know what you’re doing, and you’re doing it far better than I could. ✌🏻
Thanks Raf. I"ll keep that in mind. I'm hoping with the long handles (better leverage) and long wheelbase and a steering dampener, it will keep the twitches in control. We'll see!
Did you just go through all the work of squaring the 'bolt' and the flange that accepts it, and then just weld it up anyway? Coulda just kept it round and welded, and saved 5 hours, or so.
Hi Paul I’ve seen most of your work. I’m sorry to say i think your going in the wrong direction. I have a idea I’d love to share with you. NO ONE IS WORKING ON MY IDEA. I’m working on a gravity car No motor at all.
This is quickly becoming my favorite CZcams channel. This build has me intrigued

So can learn some ideas 💡
The ergonomics look great.

Loving the build.
Did i miss why you didn't go with a leaning suspension?
you sir are an amazing designer. I loved your idea for homeless housing.
This is already alot of fun
I'm surprised you are not using an electric drive. I understand you already have the gas engine available. Can't wait for the next episode.
Looks like the KPA is setup for good scrub and the steering is different but should work OK. Ride may be a bit rough with the straight axle and narrow tires but it will corner flat. I design reverse trikes so I find these home grown designs interesting

You're the opposite of Mike Patey. You're both great. Just different.

👍🏅👍🏅
Nice project, but a little positive caster would be advisable (looks like it doesn't hava caster at all?).
It does. I've taken the advise from my engineer friend Bob Stuart who suggested placing the king pin 2-1/2" forward of the tire patch and 1" inboard as well.
@@paulwelkinsdiy I see, never mind me ;-)

In Washington state the legal limit is I think 20mph for electric or gas assisted bikes or trikes. Limitless if you have pedals only. Go figure...
@@paulwelkinsdiy Yeah, but they don't have to _know_ it goes that fast! ;) An e-bike will go way faster than that down a steep hill! hehe

I just have enough room for the standard three pedals. A tight fit, but so seems to be EVERYTHING with this rig!

Quite possibly, but I have good dental coverage and fair Kidneys. Again, this is not a rough road trike. It will strictly be used on paved roads.

Will your camping trailer be stout enough to be pulled by the trike?
The intent wasn't to have this small trike pull a trailer (not that I couldn't) but more intended as a commuting vehicle to work and back.
@@paulwelkinsdiy - I was just thinking that it might make for a fun weekend camping vehicle.
When you shift your arm is out of the car.
Only if the sides are flat. It is snug though.
Good observation. I already installed a side panel and yes, It's gonna be tight! Not what I wanted but IF I'm going to use the acrylic wind screen I have to keep to the width of the windscreen.
@@paulwelkinsdiy maybe a small buldge on the sides

A tadpole trike with muffin tops?

I can see a potential issue with your steering angles. Let me know if you want more information. ✌🏻
Thanks David. I'll be giving it a down-hill roll test soon. If I have issues I'll get back with you!
@@paulwelkinsdiy Good to hear, but be careful as there’s a possibility that the steering might be very twitchy, especially at higher speeds. 👌🏻

By the look of things, I’m pretty sure you know what you’re doing, and you’re doing it far better than I could. ✌🏻
Why build anything, that will crush your feet and legs, in a low speed front end crash?
I had a friend build a vehicle with steering like this. It was very twitchy and he nearly crashed as a result more than once. Caution is advised!
Thanks Raf. I"ll keep that in mind. I'm hoping with the long handles (better leverage) and long wheelbase and a steering dampener, it will keep the twitches in control. We'll see!
No you don't want it to be "twitchy on the Freeway" but do you want to take it on a freeway?
I might give it a go, if not just to see how fast it'll go.
reverse trike is a american term most people call it a tadpole
Did you just go through all the work of squaring the 'bolt' and the flange that accepts it, and then just weld it up anyway? Coulda just kept it round and welded, and saved 5 hours, or so.
