Thanks John. I hope to complete the engine within the next few weeks. A slight delay at the moment as I have lost my 1.8mm drill bit - another it's on it's way! All the best. Andrew
labyrinth grooves are just a series of shallow grooves cut around the piston where you would normally put rings but the form a water seal on small engines. Little ones like that din't use rings or packing because friction losses are too high.
You're doing a great job Andrew - I feel inspired to order a kit myself! Just need to get over the financial shock of buying a new mill lol Look forward to your next video . Regards from NZ
Hi Clive - I'm really pleased you are thinking of having a go. Tubal Cain's series of instructions are all based around the lathe - so if you have a vertical slide etc it might be viable. I wouldn't have a clue myself though. All the best. Andrew
Great! I know I am jumping the gun, but I wouldn't have been able to resist fitting the flywheel and moving the air line back and forth on the cylinder. You know, just to check!
Ha ha. That did cross my mind but I have yet to drill and tap the hole in the flywheel for the grub screw. Looks like a little job for tomorrow 😉 Cheers Andrew
Hi andrew, are you aware that you can offset the tailstock itself to do taper turning using a standard centre. I do not use a boring tool for boring in the lathe, i use an endmill mounted in the toolpost, as this gives a lot more rigidity than a boring tool and you can even use an endmill that has had a tip broken off. Boring heads are not designed to be mounted in the tailstock, thet are designed to rotate to bore holes. Brilliant Video.
Hi Terry - thanks for the tip - and I tend to agree. I don't think my mini lathe had an offset tailstock though. However I have since used the offset tailstock feature on my SC4 lathe. All the best. Andrew
Andrew this is a fabulous set of videos, I am about to receive a kit from Stuart which I ordered after watching your efforts. I am sure that your experience will be of great help in machining it. Which boring head did you purchase?
Thanks Philip. Just be aware that the s50 was my very first venture into model engineering. The method I used to machine the flywheel maybe wasn't the best. My 10v video shows a better method. I got the boring head from rdg tools - hdm 50mm kit. I really hope your s50 turns out well. I'm very happy with mine. Please comment once you have made it, so hopefully it will inspire others to have a go. Cheers! Andrew
@@learningturningmetal Thank you Andrew, the method of using a boring head is an excellent idea. It is possible to create an offset for a taper by moving the tailstock but getting it back on centre is a bit of a task. I will have a look at your 10V video for the flywheel machining.
Hi Philip. My mini lathe didn't have a feature for adjusting the tailstock sideways. However my sc4 lathe does have that feature, so a boring head isn't needed to provide an offset. Cheers Andrew
Keep it up Andrew, your engine looks to be shaping up nicely. I think you'll be surprised how powerful it will be once it has a piston ring and gaskets fitted. The taper turning can be seen here on page 4 when I made some columns for a small table engine - www.modelenginemaker.com/index.php/topic,7451.45.html
Ha ha - I think your comparison of workshops is a slight exaggeration! - Nice looking old Myford and hands-on proper steam engines - I'm not jealous really. Looks like you are having fun. Cheers Andrew
Nice touch Andrew.
Another excellent video Andrew, I allways look forward to seeing your work, Regards John

You have convinced me that I need to build this engine!
Great! I hope you have fun!
Good luck.
Andrew
haha lol i love this so much my kids are going to purchase the kit for me for Christmas, thank you Andrew. Keep up the good work
Hi Michael, what a great 🎁. Good look with the build
Cheers
Andrew
You should be really pleased with that, great work ..... Andy
Thanks Andy - so far it's coming along nicely. Fingers crossed!
Cheers

You should be happy, you've done wonderful work, thanks for sharing.
Thanks Greg, it is starting to get exciting! Not long now I hope.
All the best.
Andrew
looking good, can't wait for next video
Thanks mate. I've hit a few problems as you will see in my next video. But it is getting close!
Cheers
Andrew
hope you get it sorted pal

Looking good!
Thanks Kevin!
Make sure if you are using the boring head make sure the slide in parallel with the ways otherwise it will screw everything up.
Thanks for the advice Ross.

So I take it no one taught you about setting the tailstock over or aligning it with the headstock?
I'm gradually learning, and the help and advice of others is very much appreciated.
Cheers

Hi just found your channel! Great stuff subbed. A workshop just like mine.
Ha ha - I think your comparison of workshops is a slight exaggeration! - Nice looking old Myford and hands-on proper steam engines - I'm not jealous really.
Looks like you are having fun.
