- One of the 2 main foot peg castings on my 1977 Honda 750 shattered the end off and had to be repaired. No welding or brazing was done. Its an interesting and successful fix. Take a look.

Such a pleasure to be invited along on these projects. Really nice, clean repair. Thanks, Joe!
Very neat repair, it looks like it was meant to be there.
Well, Here is Joe mid week.When the leg came off my 900 Kawasaki was one of the real pleasures I had to give up. We spent those endless summer days together like it was an extention of who and what I am. I have to find a buyer for it but just can't bear the thought of someone else spending time with my baby.
That repair looks like it came from the factory like that. Sweet fix my friend. Thanks a bunch my friend.
Thanks for stopping by Dean. The Kawi 900 was always one of my favorites. Maroon with a black header always looked great.
@@joepie221 That was the color. Crazy bud. I was stateside for the spring nationals and found a turbo charger for it. 8 lbs boost. ( mind this is a 20 yr old) and put it on down there. Back up to my home in Stratford ont (Where I ran that boring mill via London Ont. There is a 90 deg corner that is about 3/4 mile. I was right on the throttle and just got into a peg scraper when the front end started coming up off the road. I gingeraly got on the back brake and squared away at a sane 70 mph and headed home. I had a buddy there that had always wanted it. He was a serious drag racing nut. It (the bike) really was a handful so I sold it to him. He did really well on the strip and I bought another Maroon ride and happily let it stay as it was. A really strong 900 with the only addons aside from that true header, Black of course, LOLOLOL. The only time I lost a street race was to a stranger with a 500 Kawasaki.
That ride of yours looks and sounds like a peg scaper. With what I know about you now I am sure those pegs of yours have touched a bit of asphalt. Oh to be whole again. Have a great weekend. A dive and if you have it back tohether a great ride leaving the front tire where it belongs eh, LOL. Take care bud.
Great job keeping an old warhorse in service!
I once owned a 1977 Honda CB750F. Nice bike and a lot of fun. Good job on the repair.
I once knew a man who had owned a small machine shop. Until seeing "Joe Pie" videos, he was the best machinist I had ever seen (not CNC). He told me once that the Bikers in his area found out how good he was making "one off" replacement parts. He had a huge business doing that.
Joe, you may have just created a ton of new business, once the word gets out.
Happy 4th of July. Kick back in the shade and tip a few cold ones. ;-)
Bike work is what I like to do. Ag. Work is what I do most. Never would of thought of repairing that job like that. Thanks for the knowledge.
I'm sure its one of many options.
Thanks for calling out the misplaced hate for 303 stainless. In the real world it is strong enough and corrosion resistant enough for a broad spectrum of applications. I think the people who trash talk it don't have much, if any, experience with it. If desired, it's even pretty simple to DIY passivate 303 parts.
Honestly still weldable too, undercuts really bad, but I've made a lot of shafting with it.
Had a friend who was a fantastic body man. His KZ locked up the transmission on the highway. He was hit and run over by the cars behind him. Almost died and lost his left arm. The bike was only a month old. Nice bikes and smooth running. Great repair job. It's great to see the old bikes still going. Thanks Joe. Stay cool.
As long as you're not jumping the snake river canyon, I think it will hold just fine! Nice Job.
Lol 👍
Yes, it looks like a welding job then remachine area.
Thanks Joe for showing us this repair; it too works.
Great job again Joe! So much of your channel is dedicated to the basics and advanced details of how to machine. This was a very practical application of those basics you have shown us. I very much appreciate all you do with your channel. I have learned so much from you. Thanks for sharing!!!
Nice Joe !! Just me, but I would of press fit the key into the casting. So nice to have those skills and machines to fix it all today. Young folks today don't have either, so they pay $$ big bucks to replace / repair everything. 😮
A perfect example of "I can show you better than I can tell you!"
Nice work!
You're right about that 303 though.
You really love what you are doing! last night my AC evaporator fan started making noise, long story short a bearing hub (aluminum cast) was totally worn out. Took it out the bearing was still good, in my mini lathe made a sleeve and put it back until the new motor arrives as back up. Joe, thanks to your you videos my skills are getting better and better. Happy 4th of July from Florida!
Joe when Ì was in business I machined pump shafts from 316SS, I hated the stuff. No matter I did to stay with carbide inserts I could not get 316 to to roll a chip. It made ribbons that were razor sharp and made real nasty cuts when I got cut.
Unfortunately, I have made miles of 316 ribbons of death. But it did teach me the hard lesson of using hemostats to pull the birds nests off the lathe and NOT my tender fingers!
That 316 wire would be happy to remove a fingertip or 2. Scary stuff.
CB 750…!! That takes me back to my younger days… !
A true collectors bike…! Nice fix… ✅✅
Thanks.
Nice repair, I always like that Joe does not take the most obvious route to his solution which opens us to different fixes to seemingly impossible repairs. thanks Joe!
Found the same with 303. Most people have never heard of 303. cheer Joe
As I am an amateur machinist and dabble with the old bikes. Mostly of the off road variety. Love to see how you solve some of these challenges. Thank you
I bought a bunch of 303 and 304 drops off eBay. Got it cheap. So I used it to make many shop tools. It has some issues but they were minor. The tools I made are killer nice. I love the stuff.
Thanks joe , you've just pushed my two favourite buttons, motorcycle repairs and quality engineering 👌
Great repair Joe, I was a motorcycle mechanic for 30 yrs so I can really apriciate this
Thanks for the endorsement.
as always an awesome fix/build.... After spending 45+yrs in the Motorcycle industry I've seen that exact damage numerous times. What generally happens is the bike is laid over and only the foot peg is damaged not the cast steel mount, but the steel mount wipes out the lug on the aluminum casting... Being a self taught chip maker (not a machinist) your videos/instructions has greatly improved my abilities/parts. If you ever need help on that Honda let me know, I speak Metric fluently.
The guy I bought this bike from dropped it 2 weeks before I took it. Maybe the casting was fractured, but just failed over time. I did take that area apart once to install the drag pipes but didn't see any damage then.
Joe, 303 is indeed the material when you go for easy machining. The color is somewhat brownish compared to 316. 316 can be polished mirror like compared to 303. When I started I thought 316 was a pain to machine. Then I started doing jobs for a brewing company and I had to use 316. Cursing, burnt tools and broken taps as a start. After a short learning curve I understood how it worked. General approach; never use dull tooling because it work hardens the material instantly and aim for low revs and high feeds until the chips break short. The stringy ones are to be avoided because they're lethal sharp and mighty strong. I understand that's not for the home shop because you need rigidity, power and preferable carbide tooling. Maybe a tip for the community; when drilling 316 (can be done with HSS; push it hard too with a low spindle speed) the hole has a tendency to shrink a little which makes tapping a thread a challenge. When ultimate strength is not important I drill 0,1 mm (metric here) bigger in diameter which makes tapping easy in combination with a designated cutting compound for 316. Thank you Joe for sharing all of your machinist wisdom with us. I learned a lot during the years I watched your channel. All the best! Job
The Honda is already looking beautiful, with you attention to detail it's going to be stunning.
Thanks, I hope so.
303 is indeed amazing. I am glad you mentioned that Joe. Nice repair
Yeah, but now that side of the bike is gonna be heavier and cause you to lean that way. Ha! Nice fix.
Joe & company I just subscribed watching this first video. I have always loved motorcycles. I have lots of experience with machining , mechanics but have been away so long I’ve forgotten more than you know. I can pass on a method I learned from a welder I met who repaired automotive emblems which are white metal cast aluminum I think. He would go to a junk yard and pick up some old scrap emblems that were the same vintage as the ones he’d repair. Then he would melt them down and pour the molten metal into a piece of angle iron making his own rods. He said they welded together beautifully with no problems. So if you think about welding a damaged casing this might help. Thanks for your post.
Happy 4th, refreshing change of project
Kind of surprised you didn't go with an aluminum plug to avoid galvanic corrosion. In general I notice that most machinists don't pay much attention to it, though it is the bane of my world in the marine environment.
That would be an engineering problem not a machinist.
@@edwardkeefner3540 That would be an ecumenical matter!
I don't plan on any salt water exposure, but will apply no-ox before final torque.
Handsome repair. Now build up with braze and mill the foot-rest so it fits the lovely stainless boss perfectly?
Very nice repair. Looks better than the said professional bike repairman (weld and file looks ugly) . That's the king a job I love to do.😊
What a joy to learn from a master!
I was a mechanic at Honda dealers when they were launched, F2 had bigger valves and other modifications compared all the previous CB750's since 1969.
Forks were still way too small diameter for weight of bike though and flexed really bad.
Heavy braking from 110+mph will bend them back far enough to touch centre exhaust pipes if you have a passenger aboard (I was a bit crazier back then) 😁
I had to change crankcases on one after it fell over in a parking lot.
Points cover was smashed in, screw boss broken off and a piece broken out of the bottom, bike was only 3 days old
It's when I found shop foreman was a complete ass who knew nothing, starter cable still connected while I had hands full of a 212lb engine.
He told me he had checked everything and it was 'good to go' . Dummy left clutch cable connected then ran away and hid before I put engine back into chassis
Very tidy and creative repair. Work smarter, not harder. Thanks for the lesson Joe.
Lovely job Joe. Can we see the bike when its done. Cheers
Prior to being taken apart czcams.com/video/GG0tQnS7Xxo/video.html
Interesting alternative to the TIG torch. Thanks.
Nice neat repair that will outlast the bike
For shims under parts that have uneven surfaces. May I suggest to every one the use of motor shims. These are meant for mounting electric motors and are available in 1/2" and 3/4" clearance slots. Sizes range from .001" up to .125". Uneven mounting surfaces for electric motors can cause troublesome vibration problems on high speed machinery.
Excellent repair - that is a superb CB750 - it will pull hard with the extra CC’s! 👍👍
303 Stainless was specifically developed as a free machining alloy, so I don’t know what the other dude thinks he knows. One slightly dull drill on 304 or 316 will show anyone the truth of it.
It was a she.
Ah. Enough said. I don’t watch that channel.
Just hanging around on A saturday, bored and saw this one again. I'm not a master at working with stainless but I have found when bolting it together never seize HAS TO BE USED and the only stainless I have had on the boring mill was Inconel. We tried every trick in the book to turn a 5 ft coupler from behind a Rolls Royce Gas turbine on a pipeline compressor. 48 inches of nasty. It was like cutting an innertube with a 2 x 4. I was in training and asked the foreman if any carbide (we tyyed them all) wouldn't work can I try good old fasioned high speed would work. He was out of ideas so, a 1 inch blank and tuned up nice and sharp along with Rapid Tap as a cutting fluid along with a positive rake was the trick for success. About 2.5 rpm and a constant drip of the oil was the winner. Later that day when the head fella from the tool room wanted to see if the cutters were needing any different angles on the tools hewas making told me that Rapid Tap firstly was an oil but to be used as a stress reliever as well. I have a can at all times at the machines I have used for well over 40 years now. Great on taps and single point threading. It leaves a nice finish as well. So if there are any bewbe's reading this the next time stainless is giving you a rough time give it ago and it very well may solve yout troubles. Not having to deal with it works just fine for me, LOLOLOL.
There are a few material I have worked with and will never forget. Inconnel, hastalloy, waspalloy, cobalt chrome and monel. I see it coming....I lock the door and turn out the lights. Stainless is candy compared to those materials.
@@joepie221 Everything looks like turn em slow/slow and pound the oil to it with a wicked sharp pc of high speed. Old school methods to new age materials eh. Rapid tap used to carry a skull and cross bones on the tin but they fixed that and now supposed to be safe. Hmmm.
Great stuff. Have you ever thought about doing a video on the different materials and how some machine better than others? Good input on the SS 303
Great video. Makes me think of other things I can repair in a similar fashion.
Nicely done Joe!
A very professional repair in my opinion.
Thank you.
Yup, welding on cast material is tricky, having enough material left for this fix solves that problem - and looks tougher than the original as well.
Beautiful repair - beautiful bike, too!
Thanks. My son painted it for me as a surprise gift. I'll show the final bike when its done. The 304 stainless headers went on recently and the K&N air filters are on their way. Currently rebuilding all the brake cylinders.
Nice repair. I like.
Nice one Joe. Simple, strong and elegant.
Nice work Joe and good to hear your thought process.
Love that last line about people that pass out the BS need to go back to school. I'm going to steal that in the future, if you don't mind. Its way better than the typical childish insults that first come to my mind! 🙂
Feel free to use my statement. Be gentle when you do. :)
Nice clean repair Joe thanks for sharing
That's a good fix! Thanks Joe. Have a great 4th of July!
Excellent work Joe as always.
Nice lesson in repairs, and metallurgy. I hope you and your loved ones have a safe and fun 4th.
Thanks for explaining your logic as you go.
I love the beautiful finish I can get with stainless particularly on the lathe. We only use 304 or 317 but after a while you learn how to deal with it successfully.
Thank you.
Watching you is always a good use of my time!
Thank you very much.
Great video. Thanks for including the tips for those of us without DRO's. Also the tip on 303!
Fantastic Joe. Very elegant repair
Thanks. Almost invisible.
Nice repair Joe!
What a terrific solution. Will put this in the brain bank for sure...
Thanks for the lesson
As usual Sir, fine job !!! Experience is always the better knowledge ❤❤❤
Beautiful motorcycle and great repair,Joe.Thank you.
Brilliantly simple JOE
Nice work, sir.
great work Joe.
I quite like machining 304, but 316 is not something I would choose unless I need the extra corrosion resistance [or strength, 316 is quite a bit stronger unless my memory is completely failing]. The biggest problem with 304 is that it refuses the break a chip when turning in a lathe, unless you get your feeds and speeds just right. I'm not sure I've ever had 303 in my shop - being a hobbyist, sometimes the number of available choices in small quantities of the correct dimension isn't the same as you get if you have an account with an industrial supplier.
Very nice fix. Comparing to a modern bike, those are pretty large castings. [Some modern bikes probably have that size too, but the sportier bikes I'm used to tends to be minimal on castings].
I always thought of 303 as free machining stainless. It certainly forms chips better than 316. Less prone to bird nesting.
Great looking repair but alot of work. You are a type of person that is very creative and able to figure out to repair items.
Just make that a regular thorough inspection item - vibration and corrosion do sneaky things.
Thanks Joe , nice job ✌️
Joe, very nice repair. Love in it!
Nice clean repair!
Another Fantastic Video/repair!! Also thanks for the tip on Stainless 303!!! have a great 4th of July!!
A great repair but I'd be tempted to put something between the plug and the original casting to keep grit and grime out of the interface. Vibration from the bike will eventually loosen the fit and it will most likely be the aluminum casting that will erode away. Some silicone caulk should do the job and still allow the parts to come apart if necessary.
No-ox is the plan.
Thank you , great job
Enjoyed watching the repair, thanks!
Glad you enjoyed it
Nice repair
Another great repair! Your a magician ! 👍🏻👍🏻
As always, the preparation, thinking, planning before starting is very important. Well done project.
Nice repair Joe! Are you planning on carb and exhaust upgrades as well? Bigger bore needs better flow generally.
Always enjoyed the old CB750's , had 2 F1's , 2 F2's and a K7 which was the last year of production we got here. It was different in that the engine casings were wider at the front sprocket side to accomodate the 16"or 17" wider rear wheel.
Did a similar mod to my last CB550 super sport as well , punched it out to 607cc , bigger valves, pumper carbs from a 750 , F2, better exhaust , dual disks up front for better braking.
It was a wild ride, whole lot of fun!!
Delkevik headers, electronic ignition and the F carbs are already bigger, like the cam. The carbs have been rejetted to balance the K&N air filter/header combo.
Thanks for sharing 👍
I learned the hard way to pay closer attention to what you said. On your video on making a stop for the milling vise I thought I heard you say to use 304 (which you didn't) and screwed up and ordered that for the square part and made mine out of it, what a pain in the butt that was. I later got some 303 for the round portion of it and that turned like butter.
Nice to see the Honda 4. Good bit of info on the stainless, thankyou.
No problem 👍
One caveat mating stainless and aluminum: They have clashing galvanic potentials, if the joint becomes wet with salty water, the aluminum will corrode away like mad! Seeing that you appear to live in inland Texas (dry and no sea water in sight) this problem is unlikely to bother you.
I, on the other hand, live in an Icelandic fishing village where this is really an issue...
Is stainless really all that much worse than the presumably) carbon steel peg and bolts?
@@jaytalbot1146 Probably not, aluminum tends to corrode in contact with most metals other than aluminum - but it is usually not a real problem unless you have a lot of electrolyte like sea water sloshing around. I live in a marine environment, hence my bad experience with this.
ZERO chance of that joint ever seeing salt water corrosion.
Another great video I learned a lot from, Joe. Thank you for sharing and keep 'em coming.
Thanks, will do!
I wouldn't have picked stainless for that repair at all.
I also wouldn't have welded it. Anyone thinking that would be a good idea hasn't tried to weld cast ally. Doable, but not fun.
Reason I wouldn't have picked stainless is just because of galvanic corrosion. If that gets salt water on it it will corrode the ally underneath at an accelerated rate. Given the pocket under there that's going to be nearly impossible to clean without disassembly, it is definitely a concern.
I'd have gone with a piece of 7075-T6. It's a better metallurgical match and would still be more than strong enough. Not as strong as 303, but still strong enough.
If you're not near salt, probably not too much to worry about there, and if it does become an issue you can always do it again. So nothing lost.
It's a nice repair either way. Gotta be happy with that result.
Pie does it again - nice approach Joe and super result. Bike looks great. I miss my many decades of biking.
Nice bike, great fix. 👍
Very nice repair
Thanks 👍
Nice repair job! I hope you have a video on this bike as the Honda 750 is my favorite bike! Thanks Joe!
enjoy czcams.com/video/GG0tQnS7Xxo/video.html
Nice, Happy 4th of July
Ha, just scrapped a pair of those pieces. Would have gladly sent them to you but then I might have deprived your audience of another great video. I still have the engine I think if you need anything. 1981 900F super sport.
John 🇨🇦
Nice bike. I test drove the 900 custom with the split H/L trans. Didn't want to take it back.
Very cool indeed.
great job!
Nice work as usual Joe, happy Independence Day, keep them coming, and be well
Nice job! Completely agree with the comment on 303 vs 304 and 316. Lots of 304 and 316 in my industry, and they are not nice to machine.
They cut OK, but checking an o'ring groove and finding you only have to cut .001 more is bad news. the tool pressure surface hardens the material then yields all at once and your .001 target dives into much more than expected. Heavy cuts...Good Light finishing cuts...a gamble
