Hi Paul, perhaps you should check the perpendicularity of the first hole you bored. At 15:11 it looks like the workpiece was clamped at an angle. Thanks for the entertaining video as always, keep it up!

this reminded me of the days when v-brakes were new, and i was poor. i took some cheapo italian(?) canties pressed from flat aluminium with turned inserts and questionable strength ball holders for similar post pads (aztec tho). then i took some literal aluminium door handles i found around, a hand saw and my trustworthy russian hand drill with my only bit, and made some v brakes out of the handles. during the times of drilling-force-milling the holes the tv reception went away in the neighborhood, which was extra fun. still have some parts, they never failed me.

I was really into bikes when I was a kid, hence why I’m watching you I think. Any ways I liked the bigger cranks for climbing the hills in my little town. I didn’t have any real good bikes just junk I’d find out we could get from the local roses, Walmart, Kmart. Sadly there was no mountain biking magazines in the stores either. That was not a thing. I don’t think this type of bikes came in out area till the 90’s. They were all road bikes at the stores, the typical ten speed. It was fun though as a kid putting two or three junk bikes together and making something.

It did take a while for mountain biking to catch on. It came up the coast from California, and then slowly spread East. That's great you were tinkering as a kid. I hope you're still doing something with your hands.. Thanks for commenting....

I was one of those that commented on the cantilever frame behind you in the last video. I was so taken with the upper portions of the frame that I didn't notice the drive train on it. But I'm still diggin' the Waznot. I wouldn't mind if you go through this build and heat treat it or whatever you need to do to it to restore the temper to it. And then compare it to the original Waznot. But if that doesn't happen, no problem. Anything that you do is interesting to me and your other followers.

@paulbrodie Thanks Paul. I know that you have had more than your share of health issues in the last couple years. I'm glad you're doing well. I'm healthy but several family members are not. I'm tired of visiting hospitals. I'm ready to get back on my bike and hit a trail. I hope your bike show is a massive success.

Nice to watch you work. I was a machinist from 1975 to 2000 in a shop of about 50 machinists {electronics company}. Could not help thinking "no I would do that differently" on many steps. Still brought back long ago memories. Very enjoyable. Will watch the next steps and I imagine I will be thinking that "I would do that another way." Good work.

Thanks Dan. You are right, there is no One Way to do a job. Every Machinist has a slightly different approach, and, as long as the finished product is good, that's really all that matters...

They might not be the lightest weight rim brakes but they look very cool & well built.

@paulbrodie 5 ай бұрын

Yes, I wanted Strong. The IRD brakes I discussed, and used the hardware from, were very light, but also very Flexy.. When designing parts it's not easy getting the right combination of strength and light weight. Thanks for watching...

Doing the chamfer- two ways come to my mind, one use a large custom counter sink Or Use a rotary table with a ball nose endmill and a tapered angle endmill and blend the taper into the radius. Thes second way is much more labor intensive though.😂

Whoa wait that spindle bike is great. I came across the same thought some time ago although I’m in no position to even think about building one. Would it be possible to have an episode dedicated to that concept, or at least some more details about the way the drivetrain is built. Because weight aspects aside this concept just makes a lot of sense (to me at least). Great channel Paul & Mitch. Much appreciated, makes me long for a Brodie or a Romax more and more.

Thanks Paul for another great video. Always enjoyable to watch you work and plan things out. One thing i noticed and perhaps a moot point but at the 15:19 mark of the video the stock appears to not be seated flat in the clamp. It’s just the first hole to receive the brass bushing that will not be at a true 90 degrees to the top and bottom face me thinks. Most likely not a big deal but is it worth checking before final assembly? Hey its great to see the Tiger Cub in the background, best of luck with the little Tiger Cub that is a nice machine………wayne bergman

@richvandervoort2950 5 ай бұрын

Ideally the countersink in the brake arms needs to be spherical so the pad angle can be adjusted. Any other shape will not allow the angle to be adjusted except on the axis of the hole through the brake arm. Also note the pads can be adjusted on the axis of the brake pad post.

@joell439 5 ай бұрын

Paul, it probably doesn't matter much, but if you didn't notice when you reclamped the part @15:14 the bar slipped up a couple of degrees when you were tapping the end stop. I suspect the resulting bored hole is not perpendicular. Loved all the activity going on in the shop this week. Wish I could make the bike show and shake your hand.

@ThriftyFramebuilder 5 ай бұрын

I came here to say the exact same thing! Pad alignment will be adjustable, so that won’t be an issue. And I’m guessing the two arms will have enough clearance between them that there won’t be an issue there either.

@ 7:30 or so - did you use a ball-end end mill for the hemispherical “pocket?” - by rotating it in the rotary table?

@Hurc7495 5 ай бұрын

they make raduis endmills that aren't ball nose, they have a radius but still end with a flat face perpendicular to the shaft. perhaps you could find one in the right size? if not just grind a drill bit!

I thought Biopace had something of a comeback with triathlete groups as they didn't need to learn 'correct' pedaling technique? Looks like a 7/8" ball end mill to do brake arms or maybe you used some woodworking router bit ?

@stevesutton6093 5 ай бұрын

Great work as always Paul but I too worry about the loose jacket around machinery. When I was young, 50 years ago I witnessed a guy having his long sleeve loose fitting shirt snatched off of his body by the lathe he was using literally in the blink of an eye. Luckily for him it was an old and worn out cotton work shirt which ripped apart before he was yanked into the chuck. I suspect that the denim jacket you were wearing in this video was substantially stronger than what he was wearing. Please be careful as you being pultruded around your lathe would deprive us all of your genius.

I have a shaft drive Bike lurking in the garage somewhere. I loved it's positive drive far superior to chain drive in particular for climbing banks rocks deep pot holes etc. the main crown wheel in the bottom bracket being made from cheap monkey metal cracked up and I have not been able to replace it. whilst not completely shattered it is severely cracked sufficiently enough to lock the drive chain I know shaft drive bikes have a poor rep I think mainly from folk who have never ridden one.the bikes main down fall apart from the cheap crown wheel was the lack of gears, this though was not a problem where I live no big hills. this large framed bike with it's 28 inch wheels moved along at a pace I could not match with the large framed geared bike I also ride, never at the same time or the slightly smaller mountain bike I use for every day.

@whateverbikes 5 ай бұрын

It doesn't have a bad rep per se, it just not very widely used because it has some very clear downsides compared to other (more common) systems. The main one is that it is not very efficient. Even the few percentages lost in friction are important in a muscle driven vehicle. The shaft also means the chainstay has to be straight, with is a problem. Wide tires, and short chainstay lengths mean the chainstays need to have curves or needs to be dropped like on many gravel bikes. Not having a good way to add multiple gears is a big drawback too. Lastly, it's expensive because you need a special frame for it - as everything is integrated - and there are no standards, so it's expensive to make and when things break you have a big problem.

@davidprocter3578 5 ай бұрын

@@whateverbikes As you know I must agree with much of what you have said, Certainly production costs are heavy by comparison and the designs clunkier due to the shaft drive restraints. And whilst I am constantly told that chains are more efficient , my legs tell me a very different story.Of course gearing by nature will be restricted to hub or crank gear sets another power loss due to friction. But it must be remembered there are all the plus sides to the equation that we have not really addressed. On a city bike for instance you can ride to work in your suit without fear of trapping trouser legs in chain sets, or smearing grease every where, Shaft drives are less prone to snapping as chains do under hard pressure unless regularly changed, they are safer with little kiddies fingers around them less prone to damage from rocks sticks other competitors pedals, in fact for down hill racing there could be a lot to be said for them, we all know of the problems confronted by the down hill fraternity. Gear drive failures being extremely common.[ I include shifters] There must be more plusses but age and time wield a big stick to finish it would take a dedicated engineer or two to produce a decent competitive down hill shaft driven bike and probably loads of money, so not going to happen any time soon.
