Interesting Jason! I've not started on my heads yet. I think I will try taking a few thou at a time off the bottom of the rocker posts to try to get a tight lined up fit. I'm going to use rimfire vr2 (maybe long reach) plugs but will try to get hold of a thin sided box spanner to work out how...

Very interesting Jason. To be honest I think I missed the reference to a "small" chamfer at the bottom of the liner. Cheers Andrew

Hi Brian Thanks for the mention. I hope you manage to get the engine running at some point. Don't give up! Cheers Andrew

Looking good Brian! I'm looking forward to seeing this engine running. Keep up the great work. All the best. Andrew

Thanks Scott. Unfortunately it can become a bit of an addiction! Cheers Andrew

Thanks Kees. Your 3D printed v4 looks amazing. Yeah I only run for short periods, so no fans needed. I found that the only weak element of the V-twin design is the tiny brass connector between the gear case and the crankcase. Otherwise the engine runs very well. Cheers Andrew

I've made both the Hoglet and Jerry Howell v-twin. Both builds are documented on my YouTube channel. The playlist for the Hoglet is here: The JH v-twin is a more complex build. Cheers Andrew

Hi James Don't be put off making your own piston rings. It's fun and you will get a real sense of achievement. My video below shows the method I used for the very first time. I've used the same method several times since then and always had great success. It takes less than a day to make several...

Just for info. The odds n ends engine drawing shows a Honda cm-6 spark plug which is M10 x 1. Mind you, when I made mine I used a 1/4" x 32 plug cos that is what I had kicking around. I hope you get it running soon. Cheers Andrew

Kripto beat me to it! Take the easy option and buy a couple of Mod 0.5 gear cutters. You just need to modify the distance between centres, as in my video.

Ha ha. Unfortunately it takes me ages to make a nameplate and I have too many other pressures on my time. I don't mind doing the odd favour though.😉

Hi Brian - thanks for the shout out. Your solution looks good. For info - I managed to find a geared motor on eBay. I've pinned the following description to my video explaining what I later did........ I decided to replace my starter motor with a geared version. This motor was suggested by...

Hi Brian If you have a nameplate design in mind I could try to engrave it in brass. I would need your design in jpg or png format. I would then use Inkscape to trace the image and convert into svg format for importing into Fusion360. No promises but I would be willing to have a go. I live in the...

Hi Colin I hope you manage to get your dad's old engine running. I seem to recall that the most difficult bit for me was cutting the valve seats. I think I decided to change the design a little and made some valve guides to press into the 'head'. I should complete my Jerry Howell v-twin soon and...

Hi Gordon I made a Philip Duclos odds n ends engine in 2021. It's exactly as per the drawings and runs really well. I don't understand how others have used a different carb, as its an integral part of the valve assembly. Have you got the fuel tank outlet level with the carb inlet? If not, that...

Thanks Mike. I have received them and I've replied to your email. Thanks again. Andrew

Thanks Mike. No rush. Cheers Andrew

Hi Mike I went last year and I found it very interesting. Unfortunately I couldn't afford a brand new Myford! The main drawback for me was the rail service. The trains out of Leamington Spa were full with standing room only and it took me over 5 hours to get back home near York. This year I saw...

Very nice! Excellent tick-over. Could you share how you set up your starter motor system, including clutch and gear ratios? I'm trying to make something similar (I've got a scooter starter motor and considering a sprag bearing) but I'm absolutely rubbish at design. Cheers Andrew
