Another great video. Glad to see you back in the shop after working on your Arduino tricks for the winter. I wonder how many viewers are old enough to understand the Packman clearing the screen after the information is displayed? Love the setup on the rotary table for a dividing head for the gear cutting. Been a really mild winter here in New England so I was able to stay in my metal shop all winter. Many years I head to a warm part of the house and work on model ships. Dick B USA
Hi Andrew I was a toolmaker for many years (now retired) and have built a lot of Stuart engines, including the V twin. It was a struggle because they had lost their original drawings but got there in the end. My next project would be an ic engine and think the opposed twin you are building is perfect however I don’t have the indexer to make the gears. Budgets sadly are limited so would love to get your spare set. I guess you have lots of requests so I won’t be disappointed but if you are able to let me have them I would send photos of my build. Anyway thanks for your videos; it has motivated me to move on. Many thanks Chris
Hi Chris Unfortunately the gears were snapped up within an hour of me releasing the video. Personally I think the Jerry Howell Farm Boy would be a better bet. It really is a great design and a rock solid performer. Unfortunately that requires a set of gears too. It takes a lot of time setting up for gear cutting and sadly I just don't have the time to help you out. As I mentioned in the video, HPC gears in Chesterfield might be a good option and it's certainly worth checking out the cost. I hope you manage to work something out. Once you get into IC engines you won't look back. Cheers Andrew
Thanks Andrew, no problem about the gears in fact I’ve managed to borrow a dividing head (could never justify the cost to buy one!) Love your videos and how quickly you’ve developed your skills….really impressive. Regards. Chris
Well done. Next time I visit a certain shop I'll try to take look at their cutters. They have a lot....... Noble of You to offer gear cutting but I asure You, I'm building any such engine!
Nothing wrong with taking a little Arduino break while waiting for the weather to warm-up. Some quality gear cutting! Clickspring has an excellent 4 part video series on shop made gear cutters, although I haven't given that a shot yet.
Hi Tim - I never thought about that option. For Mod 0.5 I guess the same gear blanks could be used but reduce the depth of cut (42 thou for Mod0.5) by the undersize amount. Food for thought and maybe worth experimenting with at some stage. Cheers Andrew
I too have played around with Arduino stuff but Im not that good at programing, Im impressed you got that display working so well. Sure is amazing what the hobbyist can get and do these days.
Yeah I've been programming stuff for the past 45 years - from handheld psion organisers to mainframes. It's amazing what can be achieved at home nowadays. Cheers Andrew
Hi Andrew, thanks for the videos, entertaining as always. When you were taking a break because of cold weather, I've been doing the same because of the hot summer we've been having in Australia this year. I used that time to watch your Farm Boy build series, an object lesson in perseverance producing excellent results. Very impressed by your gear cutting set up, I've only used the manual dividing head method for that. I've also had the same difficulties getting cutters for gears nominated on drawings so buying stock gears from a local supplier who has an alliance with KHK gears in Japan has been the most cost effective solution for me. I was wondering if you use a gear tooth vernier, off camera, to check the size the first tooth before proceeding with cutting the rest?
Hi Alan Thanks for the feedback. I must say that the Farmboy is my favourite engine. Jerry Howell did a great design job. I've not heard of a gear tooth vernier. I'll do some investigation. Cheers Andrew

The spare set of gears have now been claimed. As I mentioned in the video, HPC Gears in Chesterfield might be an alternative option.
Your work is truly inspiring!👏🏼

Hi Dick - glad the weather has been kind to you over there. I must try to get back into the swing off things.
All the best.
Andrew
Well done, heart in mouth time as you come to the last tooth, they never seems to be enough room!
Yeah - the rotary controller gives an element of reassurance.
Cheers
Andrew
Thank you Andrew for the video and update. Cheers
Cheers John!
Another great video Andrew. Thank you for taking the time to explain the process that you follow to cut gears, you certainly get good results!
Thanks Graham!
Not only metal turning but electronics too. Best wishes.
Hi George - just a bit of fun really.
All the best.

Hi ANDREW,
Great job on gears cutting.
I like the temp and humidity display you've done 👍👍👍👍👍

Thanks Olivier! I need to try to get back into the swing of things. Too many distractions at the moment.
Cheers
Andrew
those gears did nice mesh andrew, well done !
cheers ben.
Thanks Ben - it's always satisfying when they mesh well together.

Thanks Douglas. I hope all is good at your end. I'll check out Clickspring.

I understand not working in the shop during cold weather. It's been in the negative number F here. Thanks for sharing 👍
Cheers Craig!
Hi Andrew, welcome back.
Thanks Rich!
If really required you could do a slight "profile shift" on the metric gears. To adjust center distance.
Hi Tim - I never thought about that option. For Mod 0.5 I guess the same gear blanks could be used but reduce the depth of cut (42 thou for Mod0.5) by the undersize amount. Food for thought and maybe worth experimenting with at some stage.

Great result on the gears. As you say, set up is key. Completely baffled by your arduino tricks but as long as you are having fun 😊
Thanks Tim. I've been programming stuff for the past 45 years. How things have changed!

Hi Andrew another great job, have pm'd you
Hi David - I'm glad those gears arrived intact.
Good luck with your build.

Not at all. I just try to help other model engineers where I can. It's a great hobby.
