I'm an industrial air compressor tech in Texas. We joke that most days are like an episode of How its Made. The variety of customers we have is amazing. Everything from a Yoga studio, to machine shops, to power plants. Last year I went to a shop in Waskom, TX that makes the wheels and axles for trains. The process was similar to yours, but on a much larger scale. I enjoy watching your videos. Keep up the good work.

Fun fact: I used to build and rebuild bearings for trains. They were all roller bearings. Every surface had to be meticulously prepared and tolerances were very tight. They were also huge... 7.5 inch, 9.5 inch and 12 inch inner diameters. The rollers were chrome plated. Fully assembled, 2 roller bearing assemblies, 2 end caps, a bearing cup, a spacer and pumped full of grease... They ended up being over a foot long and quite heavy.

The radius on the outside of the flange might be related to resistance to cracking. A major cause of derailment is broken wheels. One cause of wheel cracks is a wheel sliding during braking which creates a hot spot which can create a hard spot. The hot spot creates a red oxide on the wheel, "rule of thumb" is replace the wheel if the red oxide extends more than 4". My office mate in grad school was working on measuring stress in the wheel tread to develope a scientific method to determine which wheels needed replaced. His "samples" were 600# railroad wheels.😊

The flange and rolling surface are actually shrunk on steel "tires".

@steveboylan526 Жыл бұрын

The key reason for rounding the edges of the flange, especially in model practice, is to prevent cutting slices off the rails. A sharp edge will happily peel lengths of swarf off aluminum, brass, or steel rail.

@billmoran3812 Жыл бұрын

I’m glad you mentioned the bearing clearance as a factor in railroad wheel tracking. This is a big factor for locomotive wheels. I’ve actually done the bearing shim adjustments on a diesel locomotive to stop its tendency to walk from side to side. The axle travel is limited by rubber cushions at each end. Spacer shims are added as necessary to maintain the specified free clearance between the axle and the cushion. Too much clearance and the locomotive will rock violently side to side, possibly even derailing! It’s hard to believe a few thousands of an inch of shims can have that much effect on a 425,000 lb locomotive.

@brucematthews6417 Жыл бұрын

I've never done a railroad project of any sort. But hearing you talk about the coning and "differential" action and float in the axles made me realize that it's not just the need to ride the wheels up on the cones but also to permit that same coning to occur when the "straight" frame of the engine. is going around a bend. the mid frame engine axles are going to be shifted to the outside and the more front end rear "end" axles to the inside by how the frame sits with respect to the curved track. You're right, those old timey railroad engineers knew a thing or three! ! ! ! Axle float isn't just a cop out, It's 100% a requirement.

More years ago than I care to remember, a shaft failed on the main sewage pump on the ship I was 3rd Engineer on. The only material I had to hand, about 1,000 miles from land, in the Indian Ocean, was some 125mm dia steel bar of unknown origin. I had to cut off the amount needed with a hand hacksaw. To make matters worse, we only had a couple of spare blades. I had managed to put the horrors of cutting that in the dim recesses of my mind, then you managed to reawaken them. Looking back it was "Character Building".

When you're masking off area's for painting you were correct in using one big piece of tape but instead of cutting the tape away you can instead use the edge of the blade and scrape it along the corner down to metal there by giving you a perfect edge. In some cases you can even use a file. Works like a charm.

Fun thing about train wheels, is they actually also have a "S" curved crossection, to make the wheel somewhat springy in diameter. This is instead of spokes making the wheeldisc springy, the way it was done on early trainwheels. Of course only really ambitious model train wheelsets also model this crossectional feature. Personally I love the beatiful early types of spoked wheels. There is a lot of technology going into real trainwheels! Among the most problematic things in the 19th century, was trainwheels failing, breaking or loosing their steel tyres. This was a very serious safety problem, but a German Physicist Helmholtz finally came up with a clever statistical concept of "mean time between failiures", which drastically reduced these accidents. A concept many of us recognize in relation to computer harddisk drives, where the number of hours "MTBF" gives you an idea of expected servicelife. This way of turning the wheeldisk tapers is very good! Some people resort to ground form turning tools, but that isn't a great idea on many small hobby lathes.

Another fascinating video on wheel turning. I made all possible mistakes on the first wheel I turned but I have since turned literally hundreds. I am the fleet maintenance person for a miniature railway and we have nearly 40 cars with eight wheels on each car. Wear and tear means that we have to re-profile most of the wheels at some point so we found it worthwhile to grind up a profile tool to shape the outer rim of the flange. I would consider doing this anyway considering that you still have another four wheels to do for the loco and will need to re-profile them all in the future. We do the final profiling by chucking the wheel pairs between centres. This gets each wheel of a pair absolutely concentric with each other.

If you want to get perfectly cut tape around any kind of relatively sharp edge, you can tape over the whole surface, then tap a rubber mallet around the edges. Those edges will end up cutting the tape perfectly around the entire shape. It’s a quick and easy way to get very sharp edges on the paint job, and saves a fair amount of finishing work later. It’s something that a lot of people seem to use when taping off automotive engines for paint.

I am enjoying this project quite a bit. And yes, peeling tape and getting the reveal is very satisfying. As a small thought, while it will not matter in this project, that undercut at the end of the wheel journal in a larger project can cause a problem. The square edges can give the stress gremlins a place to work their evil, causing cracking and such. The fix is to use a round end tool and plunge in at an angle. Of course, you already know this Quinn, I am writing this more for your fans who do not. What brought this to mind was something on Jason's Rebuild Rescue channel. he was looking at the seat bases for the Pilot seats on the 401 and there were cracks formed due to corners.

can't wait for 20 years from now when blondihacks singlehandedly revitalizes the american rail industry by building a whole ass 300 ton steam locomotive

There's a guy in South Australia building his own full size steam loco. Hell of a project.

Ohh Quinn, you were just itching to get your Phalanges on those flanges, weren’t you? 😂 I bet you’re feeling pretty Chuffed about it too! Sorry if I’ve derailed your train of thought, hope I haven’t gotten you too steamed up about my comments 😅 but it’s certainly nice to see lathe back in service. Love from Germany. ❤

Ahh the beautiful nightmare that is 316L. The turnings that go everywhere and don't give a rats bum about your magnet on a stick. The chips that go flying out of the lathe bed and ways when you try to coax them out of the corners with a brush.

At the 21 minute mark, that red wheel looks so good it makes me want to put on a Kool-Aid man costume and bust through a wall whilst saying "Oh Yeahhhhhhh"...

I don’t have a bandsaw, I just hold the stock backwards in the Chuck and part off bits like this 👍

5:00 Excuse me, we do have Hockey here in the states.. Granted, its not as popular as football or baseball, but us in Massachusetts do love it. Aside from that, its more like one whole baseball just squished flat.. Those hockey pucks are heavy as the dickens.. I have loved this series so far as my friend and i made a steam locomotive for senior project in High School Machine shop class. We made bronze wheels but so far its been pretty much the same work.

Something I found useful making the tender journal bearings (if you haven't finished those already!): after turning one end and cutting it off, use a collet pot chuck to hold 'em to face and chamfer the other end. Worked great for me.

The railway museum in York, UK, had an exhibit where kids could roll different wheel sets down a curved track. The wheel sets had different shape tyre profiles on. The cone shape is the only one that made it around the corner without flying off. A great way to learn how the wheels work 👍
