Cylinder Boring & Honing - ep52 - 7.25" Gauge Steam Locomotive Build

In this video we bore the cylinders out on the 7.25 " Gauge Steam Locomotive Build the Bridgeport milling machine and the Harrison 12" swing lathe. I also hone the bores when the machining process is finished.
I took my time on these cylinders as this is the first time I've ever done such machining. I was very lucky to have had the advice of my friend Chris who has undertaken machining large cylinders similar to these, so a huge thank you to him.

Great work Matt 👍

[@MattChiversWorkshop]

Thanks Mark, Hope your well! All the best, Matt. 👍

[@RB-yq7qv]

Hi Matt very nice job.🤠😎😀😀😀

[@MattChiversWorkshop]

As always RB, thank you, it's very much appreciated. Can you smell the steam and oil yet?? 😂. All the best, Matt 👍

[@union310]

At last!! Someone who knows how slow a boring head should run at!

[@MattChiversWorkshop]

Thank You, I just do it all the way I was taught by seniors in the trade over the years. All the best, Matt 👍

[@TRAINBUILDER]

Great video 👍🏼🚂

[@MattChiversWorkshop]

Thanks Trainbuilder, much appreciated. All the best, Matt 👍

Great video mate 👏👏 I’m going to bore my 5” gge. cylinders on the Mill ( 1 1/2” bores.. by about 3” long). This… after having faced the casting ends parallel using an expanding mandrel, and an aluminium sleeve in the fettled cast bores. After watching this, I’ll now add an extra step, and skim the rear faces again on the mandrel in the finished bore . Thanks for that tip 👍 Regards Robert

[@MattChiversWorkshop]

Hi Robert, Thank you that is much appreciated. Yes a little tip I was taught by a seasoned pro, glad to hear its useful to others. Hope all goes smoothly with your cylinders, I'd be able to do that bore length on the Bridgeport, the quill will do 5". All the best, Matt 👍

[@tamarmolerick3814]

Nice work

[@MattChiversWorkshop]

Thanks Rick, All the best, Matt. 👍

[@schwarzermoritz]

Gotta say, moving cast iron just sounds good 😅 Also, and I know there's at least three ways to do anything, but blondiehacks taught me to not never do a spring cut with boring bars because they don't like shallow cut, and you're just asling for chatter.

[@MattChiversWorkshop]

You're absolutely right, there are many ways to do the same job. Now what Blondiehacks has taught you is correct for the size of machine she has, which is small hobby, the machine doesn't have the rigidity and the small tools are prone to deflection as they have no meat to them. Compared to her, I'm using a colossal size machine, its industrial size and so is my tooling, I don't suffer with these issues. All the best, Matt 👍

[@dereckmuola8301]

Nice i have the same lathe L6 great pics of machine ❤

[@MattChiversWorkshop]

Thank you, All the best, Matt.

[@J0nnyGT]

Spot on

[@MattChiversWorkshop]

Thank you J0nnyGT. All the best, Matt 👍

[@Fubar12341]

Well Done Matt, Spindle axis ......Z

[@MattChiversWorkshop]

Thank you, Did I say the wrong one?? 😂 I blame the cast dust. All the best, Matt

[@MrFactotum]

nothing boring about cylinders Matt we both have the tee shirt well done👍👍👍👍ep52 will you make the 100🤣👍👍👍 laterzzzzzzzzzzzz Kev

[@MattChiversWorkshop]

Now then Kev, definitely so, but haven't you just got the woolly jumper as you're on your second time round? 😂. I will admit I did enjoy doing them, not the mess, and thought I should maybe go straight onto machining another set of them, that soon past!! I don't know if I will hit 100, there is a lot to do on this loco still. All the best, Matt 👍

[@MicrobyteAlan]

I’ve been waiting for this boring video all week. 😁👍👍

[@MattChiversWorkshop]

I hope it lived up to the usual boring type content 😂, All the best, Matt 👍

[@MicrobyteAlan]

@@MattChiversWorkshop - actually I thought it would be more boring. Good episode, thanks

[@grumbum1]

Brilliant as usual my friend. Your care and attention to detail puts my efforts to shame. I am thinking of taking up knitting instead!

[@MattChiversWorkshop]

Thanks good buddy, there is absolutely nothing wrong with your build, anyone would think your an engineer by trade with how neat yours is 😉. You don't seem the type to do knitting.....more cross stitch, 😂. All the best, Matt 👍

[@allison47]

Lovely Matt, another boring video. keep them coming, I love them. Thanks.

[@MattChiversWorkshop]

Thanks Allison, much appreciated. All the best, Matt 👍

[@WHJeffB]

Fantastic Matt!!! Thoroughly enjoying your work. Thanks for taking the time to share this adventure with us.

[@MattChiversWorkshop]

Thanks Jeff, Really appreciate the kind comments, let's just hope I can pull it all together and steam it in 2024!! And go on an adventure steaming it around the country 👍. All the best, Matt

[@RustyInventions-wz6ir]

Nice job

[@MattChiversWorkshop]

Thanks Rusty, much appreciated. All the best, Matt 👍

[@briannicholls187]

Well done again Matt, a lot of viewers will have no idea how much time, effort and dedication it takes to initially setup then machine said parts. It’s a lot! As I know from experience, so congratulations on the progress so far, it’s a pleasure watching you and your sense of humour 👍

[@MattChiversWorkshop]

Thanks Brian, your kind comments are very much appreciated. A lot of the time the the setup of the workpiece takes longer than the actual job to machine, not with these cylinders 😂. All the best, Matt 👍

[@crazynachos4230]

It sure takes a while but every step done is one closer to being finished

[@MattChiversWorkshop]

Its sure does @crazynachos4230, one step closer to steam! 👍 All the best, Matt

[@PeckhamHall]

Nice job of the cross-hatching.

[@MattChiversWorkshop]

Thanks James, Much appreciated. All the best, Matt 👍

[@bantampop3532]

👍👍👏👏

[@MattChiversWorkshop]

Thanks Bantam, All the best, Matt.

[@moking8095]

Hi Matt, Forgive me for asking but wouldn't it have been safer to do the boring in the Bridgeport as you have more secure clamping and more rigid boring with a better chance of higher accuracy?

[@MattChiversWorkshop]

Hi Moking, the reason I didn't use the milling machine is I don't have power feed on the Bridgeport. The quill only has a 5" travel, and these cylinders are about 6". All the best, Matt. 👍🚂

[@donotwantahandle1111]

To quickly centre the cylinder is the 4 Jaw chuck, could you bring a pipe centre (cone) up to it from the tailstock and get it almost centred first off?

[@MattChiversWorkshop]

This is 100% true and I would have done it this way, just one small issue...... I don't own one, yet! 😂. I'm building this with a very limited amount of tooling believe it or not. One is one the list. All the best, Matt 👍

[@dermotkelly2289]

Great job mate. I wonder how much a machine shop would charge for those cylinders! That's one thing I never had experience in in the way of pricing up jobs

[@MattChiversWorkshop]

Thanks Dermot, A lot of money to have them machined, they would have done it a lot faster, but would have cost a small fortune. All the best, Matt 👍
