The Myfordboy Steam Roller Part 1. Double Acting Engine for a Mamod.

I designed and built this engine to replace the single acting Mamod one on Traction engine and steam rollers.
It puts the cylinder inboard in a more realist position.
I don't have a Mamod engine but am now building my own version as the engine runs so well.
Big thanks to Retro SteamTech channel for giving me some dimentions of a Mamod roller.

I will be adding more videos as the build continues as viewers have requested this. Playlist: kzbin.info/aero/PLHUJDLlTM_9WBgG8-waA4AG4INGFWOc2N

[@mikebarton3218]

Yes, more please! Can you show some details on how the reverser works? Thanks.

[@myfordboy]

I will add details in another video.

[@lwilton]

Very nice! Yes, seeing a re-engineered Mamod toy would be very interesting.

[@myfordboy]

I like that phrase. I will be calling future videos Mamod Re engineered.

[@jmumbauer]

Please continue with the roller build. I love your content, especially the build series videos.

[@RetroSteamTech]

Superb control you have with that engine 👍👍👍 I for one would very much like to see the rest of the roller build. Oh, thanks for the shout out 🙂 Cheers, Alan.

[@myfordboy]

Thank you for help with the Mamod details.

[@davidrenn6897]

Had an SR1 when I was a kid, about 60 years ago and could see potential for improvements even then! Would greatly appreciate seeing your version!

[@cousiebro]

Yes more of this please. nice to see you back to steam and casting. I thought you might of forgotten where the old Myford was

[@williamsworkshopuk]

Beautiful. I am cracking on (off-video) on the Myfordboy TE and so this comes at a great time.

[@greggschwabauer6241]

I enjoy the whole boiler construction and testing process.

[@jeffdayman8183]

I'd like to see videos of the new roller. The engine runs nicely. May I suggest an instrument chain / sprocket drive to the axle rather than the "spring belt" drive the Mamod rollers had? Cheers!

[@myfordboy]

Yes. I have a couple of ideas for the drive without the spring belt.

[@richarddoxey3508]

Yes , would like to see your version of the mamod steam traction engine!

[@bambukouk]

look forward to the build 👍 and new super mamod roller 😉

[@jamesreed6121]

Yes, I would like to see the whole process.

[@RustyInventions-wz6ir]

Very nice steam roller. Nice work

[@murmurmuram8533]

very inspiring ! please show us more!

[@LeslieProper]

engine runs nice. I like the reverse mechanism.

[@raymondjackson7982]

More please. Love these type of videos

[@kenwood8665]

Please continue with the roller build

[@RustyInventions-wz6ir]

Very interesting. Never seen this on a wobble engine.

[@leslieaustin151]

That looked really nice, thank you. Would like to see the project further on. Les

[@Blackcountrysteam]

Nice little engine more please

[@paulmeynell8866]

Brilliant excellent work

[@julias-shed]

More please 😀 always enjoy your videos

[@marcwade975]

Great work as always and yes it would be great to have detail about the reverser and the 1.5mm holes in the frame please. Thanks.

[@myfordboy]

I am preparing plans for the engine. I can send a copy to anyone interested if they email their address.😊

[@myfordboy]

I have free plans available now.

[@astravanmk2]

I have a steam wagon with a double acting conversion using an MSS loco cylinder. It runs great. The reverser is a nice touch on yours.

[@Watchyn_Yarwood]

Yes! More, please!

[@tuscanland]

Very nice!

[@Cannontime]

Love to see this!!!

[@BruceRobinson-tz8cj]

Echoing other comments, I am looking fwd to the series - maybe consider building attachments like a wagon mounted circular saw?

[@andybelcher1767]

Excellent, very well done indeed. I would like to see your traction engine, and I think you would design a really trick one. Cheers

[@myfordboy]

I did a series on a more detail engine a number of years ago : kzbin.info/aero/PLHUJDLlTM_9V0YKBU8_skP_g0QHlW7j1s

[@janosnagyj.9540]

Sure I want to see MORE! 😅

[@mark3bs]

definate yes from me !

[@kelvinsparks4651]

Very nicely done, I'm sure it will turn out as good as the rest of your creations and look forward to seeing it . Just a quick question, have you ever thought of making a vacuum engine ? I find them quite interesting, but I don't have the facilities to make anything at the moment due to a big upheaval in life .

[@myfordboy]

I have a small commercial one but have no plans to build one.

[@jrehtil1494]

thanks MFB

[@redportleft]

Yes please 😀🤠

[@nickclarke587]

Nice work! Do you have a drawing available by any chance?

[@myfordboy]

I did not make a detailed drawing to build this but may do if there is enough interest.

[@nickclarke587]

Put me doen for a set if you do, I have a Mamod TE here waiting for something to be done with it.. ​@@myfordboy

[@paulathomas4944]

@@myfordboy I'd definitely be interested. I still have my childhood TE1 traction engine from the 1960s and this might make a really good upgrade.

[@kattegatt6974]

I also have a TE1 waiting for refurbishment, so I d be interested in buying a drawing too.

[@Convolutedtubules]

Hi, what would be a good beginner project for a metal lathe?

[@myfordboy]

A good start would be a simple ocsillator or wobbler engine.

[@williamsworkshopuk]

Will you be offering this as a set of drawings like your Traction Engine?

[@myfordboy]

Possibly, depends on if there is any interest.

[@keldsor]

HI - can I ask you WHY you use this alloy zinc/alu and please tell me how much of each you use !

[@myfordboy]

The alloy makes a good flywheel as it is nearly as heavy as iron. It casts well at 500C.Can be machined to a bright finish. I buy it in ready made ingots. It is 12 % Al.

[@keldsor]

@myfordboy OK - I was planning to make it myself ... I have a lot of both metals on the shelf. If that's posible - I think melting the ALU first and the add the zinc and more heat when needed to melt around 500°C - do you think that's a path to follow ?

[@myfordboy]

I have never made my own alloys but that sounds ok to me. Data sheet:www.artisanfoundry.co.uk/product_data_sheets/Zinc_Alloy_ZL12.pdf

[@richardmilhousenixon5257]

Greets from Ukraine, Kharkov. Please tell me, how you fix caps on cylinder, they glued to cylinder, or something else? In video this moment dont show((

[@myfordboy]

Hope you are safe. The end cap is soft soldered on and the cap with the gland is secured with Loctite retainer. The Loctite seal can be broken with heat if it ever needs removing.

[@funkyole1125]

Yes.proof or it didn’t happen…

[@atomscombining9054]

very best
