Great video. I haven’t superglued much yet but looks like a great way to hold parts. You covered spring making and silver soldering very well. Thank you for letting us follow the build series. 👍

Thanks for watching

Gday Kevin, the cylinder head looks great, the valve retainer clips a bloody tiny, I’d need to buy a box full to make sure I had one for the job with the amount I’d drop and lose, great video mate thank you, take care Matty

[@Machine_NZ]

Hi Matty. Those parts are certainly fiddly to make. Thanks for watching

[@unclebobsbees4899]

Super tiny parts. Thanks for sharing your work.

Hi Bob. Thanks for watching

Hi Kevin,
The engine is making good progress... I liked the spring making in this episode.
Take care

Hi Steve. Thanks for watching.

[@Rustinox]

Really small parts. You need a steady hand and good eyes to do this. Respect.

[@Machine_NZ]

Getting older so eyes are not as good. Magnifing headsets are useful

Great progress it is beautiful thanks for posting

Hi Joe. Thanks for watching

Hi Kevin
Those bits look really fiddly, but it looks like you got a great result.
All the best.

[@Machine_NZ]

Hi Andrew. Thanks for watching. How's your engine coming along?

[@andrewwhale1197]

Unfortunately I've been side-tracked for the past few weeks. Added 3-axis DRO to a new mill, PC problems and upgraded my network. Looks like I might have to do some home improvements too, but hope to get back to the hit n miss engine soon.
All the best.

Hello Kevin. I think I would have to have a bag full of those circlips. I would lose them left and right! The spring making was quite interesting. Thanks for showing that part. Did you have to make a special tool to cut the valve seats? The engine is coming along quite nice. Thank you for sharing.
Now, I the stars align and I get super lucky, I hope to sneak out to the shop and melt some AL scrap to ingots. Hehe

[@Machine_NZ]

Thanks for watching. I completed the the valve guides/valves seats in one operation so used cutting tools I already had. Didn't need to make the valve seat cutter

[@ianbertenshaw4350]

Nice job !
It is hard soldering small parts with a big torch , i use oxy acetylene with the smallest welding tip which gets me by most of the time but if i need even smaller i have a dillon torch i can press into service . I have heard of people using toothpaste to lap in valves but I prefer Autosol or the metal polish you can get from auto parts stores like SCA brand from Supercheap Auto - mainly because it is cheap to buy ! I also used this on my hit and miss engine to put a really fine finish on the bearing journals .

[@Machine_NZ]

Hi Ian. Thanks for watching.

[@bertyjustice4424]

Great series Kevin. I have watched it quite a few times to pluck up the courage to try this build. If you are still checking comments, could you tell me how you chamfered the guides, did you use a 90 degree countersink or cut them at 45 degrees on the lathe with the compound.?

[@Machine_NZ]

From memory I think I 45'd them during parting off. Thanks for watching

[@bertyjustice4424]

Thanks Kevin, I will go that route then@@Machine_NZ

[@EmmaRitson]

making the bits is the easy bit. yours will probably fire right up.

[@Machine_NZ]

Hi Emma. Really interesting watching the progress on the '400'

[@swanvalleymachineshop]

Great job . Bit fiddley !

[@Machine_NZ]

Hi Max. Certainly fiddley especially with my eyes.
