Hey everyone! Here's are today's themes in the comments. Save yourself some typing and read first:

1) Yes, using a round piece of HSS speed steel in the fly cutter would have been a lot easier. However the square piece is what I had, and it was a good excuse to practice my filing, which I wanted to do anyway.

2) Yes, you could totally do this with the boring head in the lathe. If I'd thought of that, I'd probably have done it that way. 😀 Another good way to do it would be fixturing it to a faceplate and using a boring bar in the lathe. You need a good-sized lathe to have the mass to handle that setup, so that probably wouldn't have worked for me.

Another great video. I was trained as a mechanical draftsman wayyyy back in 1967/68 (long before CAD) and drew lots of spot faces but had no idea how they were made. So now I know, thank you

Really enjoyed this one. I hope you never get bigger machine tools, the ingenuity you're forced to employ when working at the limits of your machines is inspiring and educational.

I've watched enough of this series that I bought the PM-1 kit today. I'm just a retired mechanic with a pretty good shop, learning to use my smithy 1340. An old dog can learn new tricks, especially watching you. Thanks

Well done Quin,
It's a hobby, have fun trying, experimenting, and succeeding.
Don't change a thing, at least not on our account!
50k subs is proof.
We love your humour, your 'whoopsies' and humility.
Thank you.

I know to expect the cutting oil bit with the mug, but it still makes me laugh every time.

Really looking forward to seeing this puppy wheezing and chugging.

Had to double check I wasn't watching clickspring when you got out the tiny files for the "character building". Cool stuff, thanks for letting us enjoy this kit with you!

[vicmiller]

All I can say is WOW. Way to chase that perfection. This is going to be so cool to see the end product...thanks for sharing

Nice idea on making that spot facing tool. My first thought was using a traditional fly cutter, but if you don't have one small enough that tool took a lot less time to make than a traditional fly cutter.
I appreciate your narration explaining what your thought process was in making the decisions that you made.
I look forward to watching the next video in the series.

Yessss those Hand Tool Rescue wrenches are the best! So happy to see people using them.

Chatter and I are well acquainted. I occasionally also shake hands with danger.

You and TOT are the monarchs of machinist YouTube, I can't get through the week without my dose of Blondihacks

For your flycutter, since you're cutting soft cast iron you can use a drill blank (re-harden it if you need to) or use a piece of round carbide and grind a flat with a cutting edge on it. Kinda like a round lathe tool bit. I've done it and it works great and you don't need to square a hole.

I really like your work. You show all your thought process and now not only do you have to work out your setups now you have to think what would Joe Pie do or we will have another video on how it should have been done.

The #1 machining channel for curious beginners!

Really enjoying seeing this coming along and the attention to detail you’re putting in Quinn. 👍

[MUAW_IO]

Machining skills, tips, swarf, oil, educational content and humour, what's not to love...
(OK, the machine tool envy is a bit ugly but y'know, one day I'll have a machine shop with all the toys)

[richardlincoln]

i enjoy watching Your approch to problem solving considering machines, tooling and budget... Like Joe Pie says " ask 10 machinests to do the job and you'll see 8 different approaches, none of them wrong. "... Best Wishes Quinn...

Glad to see you’ve still got your spirit! Way to go #Blondihacks!
