Thanks Douglas. To be honest I'm struggling getting back into the workshop due to other 'interests'. It also takes up a lot of time making the videos. I'm thinking that this will be my last video series of engine builds. All the best. Andrew
@@learningturningmetal While I will miss your videos at the end of this series, I can totally understand. Building these engines takes awhile and it must be a ton more work and effort to capture and edit the video.
Hello Andrew, it's good to see you back. Sometimes we all need to take a break from a current project. You are correct thinking it would be better to wait to machine the valve seats until after the valve guides have been installed. Mr. Upshur designed a small tool to do this, and it is included with his plans for other engines. I made mine using .312 water hardened drill rod with a pin the exact diameter as the valve stems and it worked well. I think Mr. Britnell's design is similar. Good luck.
Hi Earl - thanks for the info. I will do some futher research. To be honest I'm struggling getting back into the workshop due to other 'interests'. It also takes up a lot of time making the videos. I'm thinking that this will be my last video series of engine builds. All the best. Andrew
Fascinating as ever. It is always interesting to hear you describe your thinking and workings to resolve problems. I admire your patience with those grooves. I think I might have gone with a rotary cutter of suitable diameter to cut the slots and radii. Good to see you back in the workshop.
Thanks Tim. The radius of the grooves was way too small to allow me to use a slitting saw. I wish I could have got the drawings into Fusion 360 to enable me to CNC the heads, but that was way beyond me. A jack of all trades and a master of none! Cheers Andrew
@@learningturningmetal Slitting saws can be obtained or made in small diameters. Think of gear cutters or woodruff cutters for example. These days you seem to me to be a proficient in many aspects of machining.
Hi Rich - I could have, but I didn't have a slitting was to match the diamater of the 2.5mm two flute endmill. I resisted looking for one to buy! Cheers Andrew
We also use Flightradar24 great fun to track and identify planes over us in real time. That's a very detailed part Andrew. I can understand how long it took to machine. Always enjoy your detailed explanations. ATB Nobby
Very nice work sir. You are setting high standards. I get your situation. I’m very much in the same. Juggling to keep videos coming as well as doing bits around the house. It’s hard to get to every thing. He he
Thanks Rusty. To be honest I'm struggling getting back into the workshop due to other 'interests'. It also takes up a lot of time making the videos. I'm thinking that this will be my last video series of engine builds. All the best. Andrew
You can of course fit the Myford type vertical slide to your lathe. A look on the Warco website at say the WM 240B lathe will show you how they fit their version of it to that lathe with an adaptor plate. This sort of plate you will require because the Myford T slots run at right angles to your T slots. So you may need to draw up your own adaptor plate along those lines, unless Warco make one that fits? There are two versions of the Warco hold down plate, one with 55 x 100 hole centres & the other with 56.5 x 115 centres. Nice to see you back.
Hi Andrew, welcome back. I thought maybe you had taken the BSA Bantam for a whirlwind tour of the British Isles but the explanation of the DIY projects brought me back to reality. Dick B USA
Hi Dick - now that would have been fun. Unfortunately too many demands on my time at the moment. The videos take up a lot of time and effort so I think I will have to stop doing build series after this one. Hopefully I will be able to post videos of any completed builds in the future. All the best. Andrew
Hi Ben unfortunately my availability for making engines has gone from bad to worse. My 98 year old mother-in-law recently fell and broke her hip. She's just had a hip replacement and it's now priority to get her chugging along again! No machining involved at the moment! Cheers for now. Andrew
That's interesting. I've used Rcexl ignitions on engines with larger spark plugs. I didn't realise that they also sell ignitions with connectors for the miniature plugs. Cheers Andrew
Hi ANDREW why don't you use your cnc router to cut the cooling fins ? A rought cut with an endmill and a finishing pass with a ballnose cutter. It'd be interesting.. Make a try on a piece of wood first....😜😜 BFN OLIVIER
Hi Olivier - that was my 'Plan B'. I spent hours trying to get the drawing into Fusion 360, but I just couldn't replicate the radius grooves. Maybe I should have spent more time trying to work it out. It would have certainly produced a far better result. Cheers Andrew
Angle Plate, V-Blocks and a slitting saw. Definitely quicker, and better finish? Good to see you back.
If only it was that simple. The radius of the grooves was very small and no way could I use a slitting saw.
Cheers
Andrew
Great to see you doing some model engineering again Andrew!

Thanks Nobby - adsbexchange is also worth a look.
The part needs a bit of a tidy up with some emery, but it should look okay.

Great Job Andrew, Maybe a Dermal might help tidy the cooling fins up?? Good to see you back :)
Thanks Gary. Now that seems like a great idea. I will have a ponder.
