Making a Jerry Howell V-twin IC Engine.
In this video, part 16 of the series, I machine the Valves and Guides.

Hi Andrew.
well done. I like the way you made the valves. much easier than making them in one piece. I'm looking forward next video. 👍👍👍👍👍
All the Best.

Mark Presling has many good videos on anodizing aluminum and using an ultrasonic cleaner to get everything squeaky clean for this process. While I have an ultrasonic, many times it's just brake cleaner and compressed air for general cleaning as it's so fast and convenient.

I've always used acetone. I suppose an ultrasonic would also work, but you'd still have to remove all the liquid used in the cleaner. I think acetone is your best bet. I agree, also, that your valve guides aren't going anywhere. As long as the heads don't get about 200-250 degrees C, it should remain bonded.

Hi Andrew. It was good to see how you make the valves differently to how I do. Just made the valve retainers etc tonight. Will be posting part 11 soon. Take care & great machining.

Thanks again Andrew. Great video love your work. Yes for ultrasonic. I use it to clean watch parts and jewelry. Think it will work great with machined engine/ motor parts. Have great day. Cheers!

Hello Andrew, I have an ultrasonic cleaner and with the right solvent in cleans perfectly, I bought for cleaning cartridge brass, but use another method for that now. I used the cleaner for a Boll Aero 18 that I have just completed. I'm really enjoying this series.

Getting there Andrew. Is the Loctite your idea or in the instructions ? Seems strange to me to use Loctite on sometyhing that is going to get very hot. Normally you use heat to break it down when you need to unassemble something. Regards from Australia.

Interesting video, thanks. One piece valves from 303 stainless are not bad to make if machined in sections 5 or 6 mm long. Interesting video. Steel is an interesting choice for the valve seats/guides.

Hello Andrew, I have always used straight Acetone to degrease my parts and have never had any problems. Good luck getting your mill sorted out. Be well.

[markrainford]

When milling cutters get below 2mm, I'm always wondering if it really is a four flute end mill, or somebody's just sold me a drill bit.

[timjoinson]

A bit late seeing this one. Just catching up after moving house. A lot of heavy maths going on there. I liked the way you set up the dial guage to check the angle. A neat trick. I cant really help with the mill noise, but has it been lubricated recently? Hope it isnt the bearing failing. Maybe Warco could advise.
The valve guides look good. Cant imagine they are going anywhere when it took that much pressure to get them in.

[chrisstephens]

If you know why not using an end mill in a drill chuck is recommended then you will know when it is acceptable. Drill chucks are usually held on a taper, both morse i to the quill and jacobs onto the arbour, and if you use an end mill to cut sidewsys hou inevitably get a vibration and this will break one or other taper joint. The end mill when used as you did is more a drill than an end mill and loading is axial not radial and is quite safe.
Another query on use of drill chuck as an end mill holder is the grip is less than ideal compared to a collet or proper end mill holder like the Weldon system or a shrink fit, having three line contact points and the fact that endmills are hard but drill shanks are soft, as you find when they slip in the chuck and get chewed up.
While in teaching mode😂, silver soldering silver steel can be problematic if it is not allowed to cool slowly, as it will likely harden and become brittle! Maybe not full hard and brittleness but enough to be slightly risky.

Ultrasonic cleaner with the carburetor solution designed for ultrasonic cleaners is safe for all metals and works great

hello andrew je vous admire vous faite les calculs en métrique et l usinage en impérial se qui ajoute de la difficulté

[djfaber]

Not to nitpick or anything, but is it really a V-twin, as most V-twin engines are 60 to 89 degrees, vs L twin engines at 90 degrees.
