Should make another one with 4 tires but both sets on front and back be 6 inches apart with adjustable arms so when you go to turn or lean it pushes one tire and arm higher than the other allowing full contact at all times

[@iuliancoarna6792]

at the back wheel, the axe shouldnt be weilded, weilding its not recommended on structural resistances such as the axe on the back wheel because it can break or bend in time. Use a whole piece of metal and just turning it or milling it. dont weild stuff together when it comes to structural resistances. Also for reducing the the "snake effect" add weights (cosmetics can be) and balance the overall bike, the dampers must be at a certain angle for vertical efficiency ...overall its a really good project i wanna see how its gonna be longterm.

I worked as a Tool and Die Maker for over 40 years so I have a few tips for you. ---To machine hardened steel use the carbide from a concrete drill, set the center of the top surface of the carbide about .030 of a inch below center and slope it down at around 5 degrees, machine at a very slow speed and use NO coolant or lubricant, it will cut like a hot knife thru butter. Concrete drills can drill holes through milling cutter shanks, which are usually around 58 to 60 Rc. --To straighten a shaft, heat with a torch, localized on the outer curvature of the shaft, till it turns blue, then quickly quench with wet rags. This method will pull a shaft up to .060, but if the bend is more, run a bead with a welder, again on the outer curvature and again quickly quench with wet rags, this method will pull a shaft up to and exceeding .125 of a inch, the excess weld can be removed without the shaft bending back. --When welding hardened steel, always preheat the steel or the welds will crack or fail. --If you ever want to weld cast iron, always preheat and weld with a Inconel or nickel welding rods, then let it slowly cool off, never quench in water or oil cause the weld will crack or fail. --To drill a long shaft or flange on the milling machine, clamp a large V-block on it's side, clamp the shaft to the V, side the top of the mill out, yes they do move and even swivel, so you can hang longer pieces over the edge of the mill. You should be able to get a 90 degree head to drill horizontally, if you want to do it that way. --Never, ever weld on a lathe, the beads could warp, arcs could form between the gears in the gear box and even fry the electronics of it. If you still have your old lathe around, use it instead. If you have no choice ground the part directly, a magnet works well, grounding through a live center will ruin the bearings in the center. I hope that this helps you in the future.

CAE Engineer here - just some thoughts. That "death wobble" looks sinusoidal in nature - which seems to be corresponding to the top-down shape of the bike. I would bet that a modal analysis of the frame will yeild a certain frequency in which that wobble is induced. I also have a suspicion that if you simply add a reinforcement on the left side from the front wheel "cage" to the rear "cage" it will stiffen the overall structure and limit that motion. It appears to be a force load/unload cycle due to the natural shape of the frame, likely induced by the size and load of the tires.. I can guarantee there would be a *lot* of enginering students who would love to model this for you as a project for college. I'd reach out to a couple university engineering departments and see if they are interested. Edit to add: also, its only doing that wobble on pavement, because of the increased friction between the tires and the pavement not allowing sideways slip... they bind, inducing the wave in the frame which in turn causes it to flex, etc... in engineering terms its called a underdamped or unstable system. Edit to add again: After some discussion here in the comments - I agree that you want an overdamped system to stop the oscillations as fast as possible - critically damped will not stop it quickly enough.

You would definitely want a over damped system, not critically damped. With phugoidal motion, you will only be dynamically stable with an over damped system. If you go with something that's critically damped, you can reach new steady states which will reduce your control.

Even with that grabby dual voltage gun you can get decent results. Start with a better ground, move your gun back a bit to make a better cloud formation, watch your mil thickness, and all cure schedules start at PMT (part material temp) not when the powder flows out. You can flow out powder to a liquid long before its beginning to cure just by flashing the heat. Regardless, best of luck.

I've powder-coated for many years and I recommend buying an old metal cabinet, insulating it, and turning it into a large oven with a temperature heat switch. This will allow you to coat much larger parts like control arms, swing arms, frames, etc. Then while coating hang the parts from a rack so you can just throw them right in the oven without messing up the powder. Also wrinkle black is by far the best color and the most durable.

[@IbisOffgridLiving]

Thinking the same thing, couple burn outs she be sweet

[@DJSekuHusky]

Those tires were intended to go on a fixed axis of travel, with the camber angle creating one contact patch without introducing greater drag. Usually the weight of the vehicle would also restrict its top speed. Once you freed the axis of the tire and increased the rotational speed, that deformation at speed is exactly your death wobble, since you're not only dealing with the centrifugal forces stretching the tire outward, but the change in direction is visible changing the shape of the deformation of the contact patch from edge to edge (you can see it in the silhouette on the horizon). Where it cups inward you have 2 sides fighting for the same traction with slightly different angular momentum. On a smaller scale, I've had this happen with sawtooth dolly tires on a mini bike... I was waiting on new tires to ship to me and only needed them for a few days before they arrived, but as soon as the speed got past a certain limit with those flat-bottom tires, the wobbles were absolutely terrifying. As soon as I went back to the racing "slicks" I ordered that had a more tapered curve to a centrally rounded contact-patch (and higher pressure rating), no more death wobble. Its a combination of the composition and intended use of the tire coupled with the change in load-applied geometry that's making them work against you. Overpressure might improve the shape, but then you have to consider the temperature change and the lower speed composition, so maybe try overpressure _with_ a Nitrogen fill to improve performance, that way it doesn't continue expanding once they're heated up.

[@TadhghR]

Elementary! Cheers!

[@d_rock_t]

Interesting thoughts. 👍

[@chriscross5581]

Another effect of the tires changing shape will quite literally be a sort of compound change in steering geometry. While the increase in diameter of the tire should move the projected road contact point of the camber a little bit further forward of the contact patch, theoretically increasing the trail which ought to improve geometric steering stability, the contact patch at the same time gets shorter and narrower.....and I have a gut feeling the friction might be helpful in reducing the steering oscillation you are experiencing a bit as you approach it. The added steering damper also helps, no question. The oscillation you are experiencing is known to bikers as "tank slapper" and it's basically the steering system running out of steering dampening, by part due to trail, by parts by other means. The trick is that trail in itself only gives you a more or less fixed amount of self righting effect which at speed also acts as resistance to wobbling, but the forces causing wobble increase with speed. At a certain speed, a given system of wheel inertial moment and imbalance and steering geometry will simply run out of margin between trail effect and wobble forces, and start the oscillation. Usually, bike manufacturers have this under control, but tuned or modded bikes with higher top speed or more aggressive steering (like for racing) often can have issues. Common remedies count steering dampeners and stiffer tires😉 Personally, I've also encountered this with sidecar bikes, where heavy steering due to the stiff connection to the sidecar is often tried mitigated through reduced trail, requiring steering dampeners to be added.

[@chriscross5581]

I may have to correct myself a little bit about the stuff about trail and wobble forces. Self righting forces caused by trail grow linearly with speed (not accounting for geometry changes from tire diameter change OR suspension movement), but forces due to rotation of the wheel grow exponentially with speed. Trail forces just start at a certain level due to vehicle weight at standstill, rotational forces start at zero at standstill.

[@mindeloman]

I learned about centrifugal forces as a teen out far away from home and got a flat on my motorcycle's rear tire. As long as I was over 30 mph, it rode like normally. Drop below that and he wobbled worse and worse the slower I got. Got it home. But yeah, centripetal force kept the tire "inflated."

As a 40 year vet in the powder coating industry I would suggest investing in a walk in gas fired oven and a small spray booth. Gas fired will give you a more uniform cure and color consistency between batches. You have the space and this will allow you to coat bigger parts like fenders, tanks and wheels with better quality than you’ll get with the Eastman outfit which is essentially a hobby kit. Also there is a ton of used powder coating dolly equipment with powder gun, controller and hopper online. I would suggest a mini hopper for small batches. Finally you can get small samples of powder cheap and sometimes free from dealers.

Worn-out bearings can cause lateral axle movements, which may initiate a wobble, as well as, large tread can contribute to stability issues, due to the rubber changing shape and spreading outward at high speeds, causing a wobbling effect.

[@TexasTrained]

Yes but odds are those new bearings are not the issue.Most likely it tge ig u balanced out of round tires

[@KW-ir5mf]

Try two tones. One at 1hz difference than the other. You get a 1 second change from 0 to max amplitude. Same thing happens with tires. You noticed it happens in a turn or lean. In a turn one tire spins ever so slightly less than the other. At some point you get a harmonic induced into the frame structure between the wheels and since rubber acts like a spring, well.... More tire pressure could solve the problem along with fine tuning wheel balance. You really feel the bike flex when you cruise around a corner and get a slick spot transferred to both wheels front and back.

[@Soulsender]

just another think you should check. Sport Bike are known to have high speed "wobble" going over a bump in the road. Even on perfectly balanced wheels, The steering dampener on them helps prevent that. You might try "beefing" the steering dampener up. You have a lot of spinning/wobbling mass, you probably need something stronger then the tiny stock one.

[@doogoodminds8157]

So, wild seeing those huge tires lean that much. Awesome build!

[@norlanghernandez7447]

To minimize shaking in the front tire, an additional support system is recommended to stabilize it and ensure proper weight distribution. For the rear, adding another tire of the same size would enhance balance and improve overall performance. Additionally, reducing the size of the front tire could significantly enhance the motorcycle's dynamic appearance and stability.. Just a small feed back. Great prototype and awesome job btw.

[@nelsonbeaumont8669]

I'm 58 now, we built crazy stuff when we were in our 20"s. I love the things you build. The death wobbbbbble LOL I only have one suggestion. maybe and only if it happens at a certain speed. You can test the tire balance against a different unknown issue by accelerating slowly through that speed area. We used to this with our giant tires ( 44" back then ) If it is just a tire issue it will always show up at the same speed no matter how much power you are applying.

Even when they are "wholesome", they are still ruining your day because they wield so much power over you, if they are in a bad mood, can just find something to hassle you about, and many times even when they are acting friendly, they are just feeling out the situation but are actively trying to get you with something or otherwise being sarcastic with their "Friendliness" and so you cannot let your guard down and de-stress until they actually leave.

I'd definitely consider seeing if you can get those tyres balanced out, I know your hand carving is likely to make it hard but anything will help, it really does seem to be the mass of the tyres extending that bounce if not outright causing it, that final shot really does show it though, hope the higher pressure helps too!

[@BobV1la]

You can't balance a 46 inch tire lol

[@agentcrm]

@@BobV1la You can get them closer though. Any bit will help.

[@goosenotmaverick1156]

Balance beads Sorry, should have been more clear. Trying to balance is a good idea, and I think you can do that AND use balance beads, but I'm not sure. I just know the folks with larger tires on things like dump trucks and bigger RVs in my area speak highly of their ability to provide balancing on tires that heavy, I assume similar might apply here

[@kevinsellsit5584]

​@@BobV1laYou can static balance or dynamic balance those tires, but getting them round first and also adding some balance beads after a dynamic balance will help balance all of the rotating mass of the axle. Why do you think you can't balance a 46 inch tire?

[@BobV1la]

@@goosenotmaverick1156 commercial tires are another ballgame, usually bias ply and not radial, and don't have the sidewall height that something like the tires they put on. They're also MADE to be good on the road. These big boys have way more variance in weight over the entire tire since they're not built with balancing in mind cause they're so God damn big and heavy

[@linzimumford3829]

If you pre heat the parts the powder partially melts on the surface and you have less chance of removing it when you transfer to the oven for cure.

[@jdllewellyn5802]

It is also an easy way to ruin potential for an even coating with a machine that has minimal control, if temp is high enough to reach liquefaction. It is a balance. Heat can also be used to discharge a part in the event you made a mistake. 100-120 is an ideal temperature to help adhesion.

[@Goatee_yay]

Put the steering damper to the upright so it's pre slop in cables and bell crank. If you want it even more rigid, remove the steering bell crank. You only have to change the length of the cable end to the cable body. If you mount the cable body to the steering tube arm (handle bars) and solid mount the cable ends, you eliminate the bell crank and it's slop.

[@jakedevries1455]

Ethan is becoming quite the machining master and is a pleasure to watch you craft the things you do.

[@Raven74947]

The speed wobble is a steering geometry issue. Tire balance can contribute a bit. For high speed stability add more rake to the "steer tube", which will also take away from low speed maneuverability. So it's a trade off. Check the angle of the steer tube on a few bikes and compare it to yours.

[@Virtx0929]

[@MrCptnawsm]

Hey, it looks like the oscillation you get is mainly flex in the front swing arm. Judging by how much the chain slacks on throttle, the chassi might be flexing into a radius on throttle, that then induces the wobble in the front that i guess is the part most prone to flex/oscillation.

[@bajasoobnut]

IIRC you guys have a bridgeport mill, for longer parts you can actually have it mounted to where it is over the edge of the table and then just rotate the head and ram assy. over to the side to drill the holes needed. it is just 4 bolts holding the ram onto the base. Also you can adjust the ram in and out as well to help. Just remember to make sharpie witness marks to help with realigning the setup after done.

[@JK-tu1xx]

The porpoising is because the stroke of your shocks is too short for the bike, it's cavitating at the bottom and pushing the front end into the ground as fast as it can. You'd be better served using some long stroke shocks off of something like a trophy truck.

@@venumus1 This right here. Definitely needs balanced no matter what. Gotta also consider it's not just up and down that the imbalanced tire is pulling. It's also imparting a forward and back force, which results in the side to side wobble.

Ethan, you mentioned the monster bike was a beast to turn, years ago when I first started riding bikes a mate gave me this tip, you may already know it but if not it might help if you are going around a bend for example TRY pushing or pulling the opposite handlebar only a few MILLIMETRES it is counter intuitive to what you feel is right but it will get the bike into the curve or bend very quickly DO NOT push or pull excessively or you will end closer to the road more than you ever wanted It is how the bike racing guys get right over corner to corner very quickly and very low if needed practice carefully until muscle memory can be trusted to do it automatically.
