I came across your channel, because you where mentioned over at Mattys Workshop, Spent literally all 4 hours this morning sat here drinking tea, totally mesmerised. you have a great way of explaining what your doing, and you kept my attention by cutting over the repetative bits, thanks for taking the time, ive subscribed, and look forward to the rest of the videos im yet to watch.
Very nicely done! Also it's so good of you to mention those who offered advice and help. Everyone appreciates a bit of thanks now and then, to get it in a video with running engines is no doubt particularly nice. Looking forward to the Hoglet adventure.
Thanks Stan. I receive loads of advice and it's certainly helped me develop my machining skills over the past three years - so I do really appreciate it. One of my main objectives is to try to encourage others too. If they are inspired to make an engine, then the least I can do is show a brief clip of it. I hope the Hoglet turns out well - I like to try to raise the bar a little higher each time I make an engine. It's the challenge that gives me the motivation. All the best. Andrew
Fantastic series Andrew, really well finished off. Seeing both engines running side by side........... No wonder you were grinning! Excellent. Cheers, Jon
Hello Andrew, Congratulations again on a fine running Odds ' n Ends engine. It looks really nice with the Farm Boy, and hopefully these will only be a beginning for many more successful engines. Thank you for letting me join you on this adventure. It is great to have a sounding board with whom to share concerns, techniques, and triumphs. All the best, and be well.
Hi Earl - likewise, it's been great to exchange ideas. I doubt I could have tackled CI rings without your help and inspiration. I'm looking forward to seeing your completed engine. We turned these two engines round in pretty good time I think! All the best. Andrew
Congratulations Andrew. The engine looks great and is running sweetly. Pleased to see that you managed to get the CI rings working. The compression is huge. The whole engine, which looks quite heavy, lifts every time it fires. Just an interesting coincidence... I have been watching a French police drama on iPlayer called Spiral. One of the leading actors is Phillipe Duclos! I think of your engine every time I see the credits. I have really enjoyed watching this build. I will be watching your next project with interest even though you are moving away from steam. Surely you can take the 'L' plates off now!
Thanks Tim. She runs pretty well and starts dead easy. Blimey - Duclos on TV! My video might start trending - ha ha. It's been a pretty enjoyable journey so far. Maybe time to put the green P on before I crash and burn! All good fun anyway. Cheers Andrew
What a fabulous end to a most enjoyable, informative and educational series. One day perhaps you will “show” your builds at an event and we get to see and hear them in person. Thank you for all you do. Roll on the next project. Can’t wait 😛👏👏👍😀
Thanks mate. I hope you enjoy the V-twin build. Coincidentally it looks like I might be showing my engines sometime in September at the Derwent Valley Light Railway 🚂, near York. I hope they will help inspire others to take up this amazing hobby. Cheers Andrew
Gday Andrew, I’ve really enjoyed this series of videos, each have been very informative and easy to follow, the end result is bloody fantastic and to see the farmboy running side by side is fantastic, the twin cylinder engine build sounds like it will be a great build also, I’m really looking forward to seeing the next adventure, thank you for all the effort you put in to making the videos, truly appreciated, Cheers
@@learningturningmetal Agreed. I loved the "flex coupling" used for running in the rings. As long as you keep the revs low (which you did) its reasonably safe. A simpler/alternative way may have been to use a drill set to slow speed but the lathe probably has more power & torque.
Well, I'm very happy with that! Nice one Andrew - as others have said, I've really enjoyed this series. Thanks for sharing. Lots of people looking forward to your next project including me.
Congratulations Andrew on the completion. It looks absolutely fab, you once more learned a lot and we all enjoyed watching you, sometimes going ahead effortlessly sometimes struggling. But you know, every build has its moments of desperation. Learning to handle that is part of the learning process, and you did extremely well. I already mentioned your modest yet entertaining way of narrating your work, but again: well done. I’ll bear with you in the next project.
Thank you for the very interesting series, you should be very proud of yourself . The knowledge and abilities you have accumulated since the first video when you had the lathe and mill with no experience on how to use them is amazing.lookinv forward to your next build!!.
Hi Ross, I agree. The paste I used wasn't a grinding compound. They use it on new engine builds, typically bearings. This ensures lubrication of those areas, prior to oil getting there. It's also good for new engine storage. It definitely seemed to help to run in my piston rings. Cheers Andrew
Wow, nice job! If I may suggest a way regarding the grub screws -- I like to put a small piece of solder in the hole before tightening the screw down. The solder deforms to grab the shaft perfectly, and prevents the screw from backing out. It's one of the techniques used before thread locking chemicals were invented. It produces a very tight, good fit on the shaft.
Great running engine, Andrew! I really enjoyed watching this series. It's been fascinating watching your equipment and skills progress over the years and now the sky's the limit! Looking forward to your next project after you have had your break.
Another brilliant success Andrew, brilliant work looks the dogs wotsits and sounds lovely. Thanks for posting your videos really appreciate it Cheers Buzz
Congratulations from Canada! A great project finally succeeding! I've watched all the videos for your Farm Boy and Odds n Ends engines, very interesting. I can't wait for your next project! The Hemingway spring winder is intriging.
Well done Andrew. COO who would have thought about using a bit of garden hose as a driveshaft. Did the job well though. Enjoy your break and don't go to too many nightclubs now the Government say you can. LOL Regards from Australia ,now in lockdown.
Thanks Dave. The garden hose was Earl's idea - and a great one too. I'm avoiding nightclubs at the moment. Common sense is prevailing! Take care! Andrew
Saturday morning coffee with Andrew. Congratulations on another completed build, I have to spend some time and get mine running. I am afraid I am a lot like Keith Appleton with a number of projects going in the shop all time and just plain not having the ability to finish one thing at a time so I envy you. I have the plans for the Hoglet in the Model Engine builder magazine and I suggest you look up Volume 1 Issue 1 of that magizine and check out the Open 6 for a future project. Cheers from New England
Thanks Bob - I do hope you get some time to get your little odds n ends engine running. I wouldn't like to think it's gathering dust in a corner of your workshop waiting for a bit of TLC. Maybe cut down on the coffee breaks, or maybe increase them for more caffeine! I see Randall Cox refers to the Open 6 in his Hoglet intro. I like challenges but that is taking it to the extreme! If I do manage to make a running Hoglet, I think the Jerry Howell V-twin will be on the cards. All the best. Andrew
Hello Andrew, The engine run very well indeed... and it was great to see both running together... The new project sounds good... shame you're not going to film the Hemingway kit build, it would be good to let us know how clear the instructions were. Take care. Paul,,
I enjoyed this series. Once I finish the sterling engine I am working on, I think it will be a hit and miss next. If you are still undecided, I would be interested to see how the spring winder kit goes together, and also how it works. I can't find any videos of one of the Hemingway ones being used.
Andrew you have again done a great job with your project and videos - thanks for sharing your work. Your videos have inspired me to resume machining a model steam engine that I started several years ago. I think i might try a Farm Boy after the current project is finished. Plus, I recently retired, so I'm running out of valid excuses to not do it...
Hi Jim - my plan is working then! I hope the steam engine turns out well. Having moved away from castings and onto bar stock engines I can't see me turning back. I'm hooked on these little internal combustion engines at the moment. They are really good fun. Having made the Odds n Ends engine, I think Jerry Howell was a brilliant model engine designer as the features on the Farm Boy are far more superior. Get that steam engine done and move onto the Farm Boy! All the best. Andrew
Thanks Jeremy. Once you get your little engine running, please drop me a 10 to 15 video clip so I can include it it one of mine. Onwards and upwards! Cheers Andrew
5:30 best run-in for rings is to actually run the engine. They're never gonna bed in properly if they don't have combustion pressures forcing them out against the cylinder walls.
It turned out very nicely in the end👌 As I previously mentioned that 'Timesaver non embedding lapping compound does a very similar job to the Graphogen paste. Not quite confident enough yet for the next build to be a 1/4 scale BRM H16😂😂

Personally I would go with the JH FarmBoy. The machining of the body is a little more involved but the overall engine design is brilliant. I have found two weak spots on the odds n ends....

FYI, using grinding compound to run it in will turn the aluminum piston into a lap, you will never get the grit out of the soft metal.

Nothing wrong with firing on TDC on every stroke, it will keep the plug from fouling. Lots of engines do that.
