Stickers and Thanks!
🕑 Added 2022-04-02 17:39:00 +0000 UTCHey Patrons! It's the start of a new month, which means credits have been updated in videos and on the blog to include all Rockstar Patrons who joined in March. Note that this morning's video is still on the older credits due to production lead time, but next week you'll see yourselves in there.

This month's featured book is Casting Iron by CW Ammen, another in small library of foundry work books that was donated to me. I'm excited to read this one, as I harbour secret dreams of someday doing a back yard iron pour. Hobbyists generally stick to aluminum, brass and bronze for casting because those are much lower temperature. Pouring iron is serious business, requiring a much higher level of expertise, knowledge, preparation, and safety. I don't know if I'll ever get to that, but it's fun to think about casting my own iron engine parts some day.
As always, thanks for your support everyone! You make this content possible and I can't say often enough how grateful I am for all of you.

I would try it at 300 rpm or mybe 350?

The one I have is a basic diamond dressing tool. I think I found it by looking up "diamond dresser" on Amazon or similar.

I couldnβt help noticing a pretty cool looking tool you used when dressing your grinding wheel. The one I use has those gnarly star-looking thingies separated by washers. Seems to work but leaves a fairly coarse texture on the wheel π

Perhaps, though it is explicitly two digits because it's a +/- 10 thou tolerance.

I can recall reading about a large diesel engine for one of the early dirigibles. It was a 3 cylinder (wait for it) 27 liter. The piston/cylinder clearance was over 1/2 inch and the ring/cylinder clearance was 1/8". Now that is some slop. It's hard to imagine how they got enough compression to touch off the fuel. Possibly a very long stroke.

Old engine so 3.38 was probably 3 3/8 in. or 3.375 in. rounded off to two decimal places. All the old model engineering drawings were littered with fractions, none of these new fangled decimal numbers.

I have, yah! He does neat stuff!

Have you watched the "Cutting Edge Engineering" You Tube channel? Curtis has a post showing him making a huge boring bar that is very interesting.

I did somewhat of one in a recent video here: https://www.youtube.com/watch?v=0LOt4R-mtbw&

Do you have a suggested reading list?

if you 'do a pour', all the best to you and i know you will be safe when attempting it... thank you again for the great relaxing videos on your latest build... fascinating and informative... ππ

I read that as cast iron cooking.
