the cylinder heads are not designed to flex, an air cooled engine is designed to release heat. please rethink tying the top of the engine to the frame. Even water cooled are mounted and stressed from the crank casings.
Ha - missus and kids came running in to see why I had shouted "F******************CK" at the top of my voice when the bike fell!! More nice fabrication Matt - thanks for sharing and for providing much needed lock down distraction!! Stay safe bud!!
Something I like about you Matt, you keep it real, warts and all. If you make a cockup, you show it and show the workaround of how you fixed it. Not some hero creator (and there are a few) that never make a mistake, everything is perfect first time, every time. We learn more this way 👍
Just an observation, ridged frames do need to flex a bit for 'comfort' over potholes and if there is no flex the frame may crack at the weakest point!. Also bolting the top of the engine directly to the frame is likely to add considerable vibrations when riding.
@@deadslow201 One should definitely stick with mounts designed to be stressed. The lack of rear suspesion might be OK with just super fat rear tyre if it has enough plushiness. Dunno if such fit tough. But as hardtail show bike it it's rather interesting. I don't think it will be a daily driver for anyone :).
Nice job as always..... Just a thought re the chain run... Its pretty long.... You might want to consider a sprung or hydraulic freewheeling tensioner, either sprocket or roller wheel, to make for a better riding bike. Will take the slap out of a long chain and make for smoother gearchanges...... Enjoying the build....
Nice work Matt! I’m sure you could TIG repair that cracked case. Better yet, ask fellow RUclipsr and Brit Myfordboy to cast you a new one! Send him the old one for a pattern. Have HONDA replaced with URCHFAB! That’s just my bright ideas from the couch. Keep up the good work!
Awesome build so far, very unique! When you were speaking about the flexing due to the strength of the steel in either direction, another thing to consider is the torsional strength/stiffness which tubes have a lot of, you can imagine fixing one end of a tube and trying to twist the other vs a peice of flat bar.
You hit the nail on the head rsj flange the inner around the curve and make the coil and top engine mounts to fix to that I turn forms the rsj beam effect and not look out of form , you have formed a T section frame and then I beam section where needed
nice to see not too much damage after the fall ,, good chance to weld the case up , and weld it smooth , then put your own branding on the out side ,, just a thought.
Great work as always, my only concern would be engine vibrations either damaging the new cylinder head mounts or just affecting the ride quality the engine isn't as isolated from the frame.
That fall had me jumping out of my armchair Matt. Might be easier for you to manufacture a new engine end cover - Urchfab design. Bike is looking great as it comes together. Credit to you.
Get hold of the front wheel and push and pull it in line with the frame, the first time you bump up against something the entire front end is going to fold into the front of the engine. Where you showed it flexing by levering from side to side has no rigidity longitudinally either.
Hi Matt, excellent work mate. Perhaps the tiny tabs on the frame, where the plates bolt to the top of the engine - instrad of a nut & bolt, tap the tiny tabs (maybe M8?) then the bolts can be flush, and it all looks way cleaner. Just a suggestion. Looking good mate. Cheers from Sydney, Australia.
I foresee a front wheel chock being cut on the plasma table n being made and installed on the end of the bench for the next episode, another benefit of the Xtreme Plasma table.
More industrial strength reinforcements and a heart in mouth moment as well! It could have been so much worse and thankfully it wasn't. All the best. Cheers
Matthew with the odd misstep. Having had something like that happen...maybe more than once, I definitely feel you. There is no sicker feeling than seeing something like that come crashing down, like it was in slow motion, and there ain't a damned thing you can do to stop it.
As for the exhausts, make the outer pipe closer to the block than the middle one, so that they appear to be above each other. And yes, an accident is in a small corner, not paying attention, Matt you are not the first and also not the last to do something like that, including myself.
Coming on a treat Matt. Minor set back with the engine casing, I reckon you got off lightly! Good shout using the engine to add bracing. I reckon the top of the frame at the headstock will need more strength, 1mm of movement here equals 10 of 20mm at the tyre. That'll make it feel well vague with less sense of direction than a tory politician. A lot of old bikes used the tank to provide additional stiffness, I don't know what you plan its with the tank but I'd make it strong and fix it to the frame in a few places. I think the frame looks great, it'd be a shame to add loads of bracing to it.
Be mindful how high you set the exhaust pipes, remember you gotta fit foot pegs, a brake pedal and a gear change in the area where you showed them running back through the bike. Plus you don't want the exhaust blowing onto ur feet.
Now after watching the full episode. Those lower front mounts that you changed to compensate for the exhaust down tubes. Just a thought. When the engine is under power would the torque effect couse a small twist?. I understand you making those top 2 mounts. Just thinking when the engine is powered up and under force..By the way...stay safe
Looks the dogs mate but just wondering about the chain line there will be movement in the tyre when moving cornering , heat ,etc etc it won’t hit the chain will it but I bet you’ve thought of that lol just a thought 👍👍🇬🇧🇬🇧
The width of the frame is the issue, it's a shallow beam as you say. You can add width with some profiles between the headstock & the rear of the cradle. You will definitely see that load case whilst riding, imagine being banked over whilst cornering, the mass off the engine is pushing against the suspension but any bumps/road irregularities will move the wheels off line which will then try to move the rest of the bike which will resist due to the inertia from it's own mass (engine being the main component of this alog with the rider of course). It will be exacerbated by the long forks & big front wheel as the resultant forces have a large moment over the headstock (lots of leverage). I would guess that it will slap like a good 'un! That's quite a chain span, maybe worth a couple of jockeys/guides to stop it slapping as you don't want to be running it as tight as you did during the mock up - it'll kill the output shaft bearing.
To take out the flex you could replicate the hole cut bracing but have extra metal wrapped around the head tube,a bit like folded butterfly wings so your I beam construction effectively becomes a pierced box with a spine down the middle but still has the Same appearance? After writing this I should have said wrap a plate round head tube past flex point lol
Could do a Y bracket on the front of frame to engine i would build frame from Tube myself good luck on the build go for it...also you need a bike build table be so much safer for you...
Could you put that cover on a lathe and give it a spun or brushed aluminium finish if you can't find a new one? That or knowing you, you could make a billet or welded one. Pretty sure if anyone could, you could.
Hiya could you make a cover? Build it up from laser cut laminations? You could have your own logo on it then. Quite glad you changed the front mount it looked wrong to me. Triangles are stronger 😀 keep up the good work you're keeping us vaguely sane!
Trial n error... Make n remake the parts untill they are right... My only thoughts are..A hard tail end and no rubber engine mounts....Will vibration be a problem?
i would be so easy not to of included the part where your bike dropped off the bench but you did'nt . Fair play mat you shown the world that even an expert can make a faux par . I tip my cap to you sir keep up the good work .
well as my dad used to say "if you never fuck up you never learn" its not something that all of us have not done before mate, you're just one of us...... i saw you grab it, that's how you hurt yourself mate, just let it go and pick up the pieces..... stay safe.
knew moding the sprocket on the lathe would work nice ly done by the way the cover will tig up and look good as new your not the first to drop something i once dropped a new pug boxer van off a 4 post lift it came out worse than that cover lol slight critism today i think the top new brackets looked cool and functional but the remodelled front engine mounts look a bit to industrial and not enough styling i know you may not see much of them when the exhaust pipes are on but they got to match the top ones with a bit of flair m8
Dramatic vid !!! Thanks for keeping it real !! Are you watching about after Stewart mate ? I saw a blur in the vid and I wonder if he didn't just pop over and nip off with the clamps while you were working on the lathe. Many compliments to you on how you handled that minor disaster. In the moment I'm sure I would have been throwing about tools and let flow a continuous stream of the most descriptive curse words of the kind that make most women gasp and get angry. But Matt takes it like water off a ducks back and smoothly keeps on. I will be anxiously waiting to see if you weld it up or make an Urchfab original cover as others have suggested. Crack on with it mate and remember we all have your back.........except maybe stewart lol
Can you get the oil filter off okay with the engine in the frame? Give Bitzabikes in Taunton a call, they *might* be able to find a cover in their plies of old stuff.
Hey Matt been following your channel ages and know your a wiz on a lathe basically ive lost my pins for my jd2 model 3 bender and was wondering if there something you could turn up for me as I can’t find them for sale separately anywhere cheers wayne
Freakin’ heck that made me feel sick...at least you weren’t hurt. BUMMA though! Was thinking of a comment to post regards ‘in my next video watch me fabricate a new ‘Chuck key’ for ‘Chuckee’ then the bike ‘went’... Keep at it Matt.
G'day from West Australia, Matt😉 Recon someone watching this footage may well go looking in there shed and find a side cover for you buddy. Even I went and looked lmao. Which is ironic haven't had bike parts in shed area for many a long year.😉🙂👍👍
will solid mounting the engine cause horrendous vibrations through the frame, similar to how solid car engine mounts do in a car? in the case of a car it often leads to mounting brackets etc fracturing through the vibration. just a thought
Glad you are OK and no serious damage! If that case cover needs sourcing here let me know and i will send it from US. stay safe. joe
That fall gave me a heart attack
@Paul Wieringa I wish
Weld a flat around the inside of the frame

Before modifying the exhaust fit the gear shift and foot pegs.

I love that you are taking us on a journey with you and that you show the highs and the lows. Keep on keeping it real!
Have you ever considered running another peice if flat stock along the inside of the "spine"? It would give it sort of an H-beam look, great project
I think an I-beam would look better.
It happens to us all , I just hope the frame isn't distorted , or the block cracked , look forward to more videos 👍👍👍👍

you only human ..
you could have edited it out
but you is the man
That's got more barkets on it than project binky! sorry about the bike falling off it still looks mint
Just like a real human, that's us, mate. Move on, weld up your cover, I did on my Honda. Same thing.
I love the prominent easy access to kettle!
Most important tool in the workshop. World.

I'm not into any type of engineering work or welding but I do enjoy what you do, keep it up and any news on the mongrel, keep safe.

On hardtails like this we have always attached a skateboard wheel and bearing to keep away too much chain slop.
We all make mistakes that's why pencils have rubbers. Great videos keep it up and keep safe.
Still looks awesome! Throw some gaffer tape on the case, she’ll be mint!
10 out of 10 for keeping the fall in. Other youtubers would edit it out

When that fell, my legs went flying up in the air!
I had a sphincter contraction.

More industrial strength reinforcements and a heart in mouth moment as well! It could have been so much worse and thankfully it wasn't. All the best. Cheers
Man of your talents should have that timing cover good as new in no time
Please tell me with all this beautiful work your using chrome moly flat sheet to cut that out of not plain cold rolled sheet
maybe your tank can also help removing any kind of flex?
are you planning to make it 2 to 1 exhaust or just a single per exhaust port I'm kinda curious.
A trails type chain tensioner somewhere would sort out that long chain run.
I had a hole in a VW case about the size of a US quarter, used JB Weld to patch it up. It never leaked, no problems.
Matthew with the odd misstep. Having had something like that happen...maybe more than once, I definitely feel you. There is no sicker feeling than seeing something like that come crashing down, like it was in slow motion, and there ain't a damned thing you can do to stop it.
Lookin great Matt. Sorry about the crash. Shit happens. Glad the damage is minimal
Found your channel yesterday, I've watched loads already 👍
They put the levellers on the outside so they don’t stop the tyre from going on and or so you can see and get to them.
As for the exhausts, make the outer pipe closer to the block than the middle one, so that they appear to be above each other. And yes, an accident is in a small corner, not paying attention, Matt you are not the first and also not the last to do something like that, including myself.
quisiera tener todas tus herramientas, amigo. seria genial trabajar con todas ellas. excelente trabajo...
Egad, I am so glad you weren’t hurt. Bike is looking good. Stay safe and healthy and free from covid-19
I can see a custom urchfab cover been made here!
Those top engine mounts look brillaint. Gets rid of theneed for ugly gussets.
Coming on a treat Matt. Minor set back with the engine casing, I reckon you got off lightly!

Surely it needs an urchfab custom engine cover now?
Might be cheaper too. Great idea

Heart in mouth when she fell off the bench. Really lucky only minimal damage.
Turn a new casing cover on your lathe?
Aye hey! I found your videos from the old ramp truck you were working on. 🤘
Nice video. Sorry to see it got damaged. The additions look great. Mahalo for sharing! : )
Love your work.
Thank you.
What is smallest hole what you can do with plasma (what will work without drilling it out) ?
Trial n error... Make n remake the parts untill they are right...
My only thoughts are..A hard tail end and no rubber engine mounts....Will vibration be a problem?
Chin up Matt. now you have an opportunity to make a cool finned cover.
Must be a day for balls ups,,I dropped a swingarm on a freshly painted tank lol...
Bikes coming on a treat
Fark. I feel your pain.
Doh!!! I bet you weren't pissed off much lol
hurt my knuckles on the screen trying to catch the bike ! you can rebuild that casing Matt..you have the skills ! :)
i would be so easy not to of included the part where your bike dropped off the bench but you did'nt . Fair play mat you shown the world that even an expert can make a faux par . I tip my cap to you sir keep up the good work .
Awesome fab work! Just curious, cereal boxes as templates for those brackets? 😀
I saw it fall in sort of slow motion and I did what you did Matt , I reached out to grab it from falling !😆
well as my dad used to say "if you never fuck up you never learn" its not something that all of us have not done before mate, you're just one of us...... i saw you grab it, that's how you hurt yourself mate, just let it go and pick up the pieces..... stay safe.
Great job and Another great video 👍👍🇨🇱
that cover I would take off and take to a cnc shop get them to do one out of billet, the face of it would be perfect for a cnc design of your logo.
is the top support going to be in the way of the tank
I’m curious what words were used when it fell off the table.
Matt, why not cut and change the front bottom of the frame to match the new front engine brackets, ( does that make any sense)
Matt, Sure glad you were able to let go of it and keep your fingers intact. That was scary.
So stuart let u out lol!! Thank god! Something good ta watch bro👍👍👍👍👍👍👍👍👍👍👍
It would be cool if you could fabricate a replacement cover. Put extreme plasmas logo on it. Probably a big ask.
knew moding the sprocket on the lathe would work nice ly done by the way the cover will tig up and look good as new your not the first to drop something i once dropped a new pug boxer van off a 4 post lift it came out worse than that cover lol slight critism today i think the top new brackets looked cool and functional but the remodelled front engine mounts look a bit to industrial and not enough styling i know you may not see much of them when the exhaust pipes are on but they got to match the top ones with a bit of flair m8

Real life vs the RUclips edit !
Hi Mat try BGF cafe racers CV37 0RW for a replacement for the damaged cover they have CB550 mag cover listed on eBay ,TBJ
Can you get the oil filter off okay with the engine in the frame?
Give Bitzabikes in Taunton a call, they *might* be able to find a cover in their plies of old stuff.

Most bike motors are solid mounted and in many modern bikes the engine is a structural part of the frame
