Another great video. It looks like you have made it easy for us to space holes. I don't have any of that equipment so I am looking forward to the next video. Thanks for sharing.
I sit up to the wee hours watching your videos. Been a machinist for 40 years and can always learn something new. You are a great instructor and I appreciate all you do in sharing your knowledge. Thank you and God bless.
Hi mrpeete, Good tutorial. This put's me in a better mood than seeing civilized country's dismantling their factories and sending their fabrication to China or whatever back country... Thanks for sharing
Returning to your shaper You could try to make a gear by real Hibbing Regarding bolt circles it could be done on a lathe with decisions by using the positions of jaws with small accurate level and added angle plates if needed (poor man's solution. Your camera work was excellent on that bolt circle by dividing head Thanks The old bob
The first time you use one of these, it helps to make a mistake in some scrap material. But once you know how to use it, it is great. I use it for almost all even spaced hole drilling.
Great video. Question: Where did you get your lubrication container? Homemade? It looks like a tin can with a copper tube brazed to it. Second. Lubrication for aluminum used in video? Learned recently from an experienced machinist that isopropyl alcohol works well for cooling aluminum. Thanks in advance for tips and feedback.
Great stuff.I just got a dividing head and tailstock.Not much room on my Burke mill table for all of it but small work would be ok.With your videos I'll be ok. Thanks,I truly love these old tools.
I know lathe work will cut interrupted work, i.e., the holes, so would it make any difference it the lathe work was done first? Easier on the tooling??
Hi Mr Pete. Love your videos! It's very very informative. Q: Am I mistaken? should the pilot drill be just a bit larger than the web(chisel edge) of the largest drill used? It might have saved that stubby from dulling. Also, I have a challenge for you. I noticed you didn't use trig to calculate the chordal distance in any of the four bolt circle methods. Well 60 degrees is so easy. The challenge is try seven 5/16 " holes with a BHC of 1-1/2" Diameter.using trig to find the chordal distances. Math is Fun!
Mr. Pete, looks like a very good method if you have the tools. I'm thinking it might be useful for non-evenly spaced holes too...if there was a need for such. -- Mike
it's not uncommon to find bolt circles that are unevenly spaced, that way parts can only be assembled in one position. flywheels for automotive engines are a classic example. it helps to keep the rotational assembly in balance during repairs when it can only be re-assembled one way.
You mentioned that you didn't know if this was useful. I want to thank you for taking the time to share your knowledge with us as alll knowledge is useful. Again I sit at the feet of a fantastic teacher. Thank you for your concern that this could become a lost art in this country.
When I need a smile, I come watch Lyle. Love Ya' man !!
THANKS--that made me smile

Oh, my dear, you are a polygon ...
Nicely demonstrated Mr Pete!

I sure wish I had a Bridgeport Mill so I could put into practice all the knowledge that you have taught me.
I did not like the speed when you drill with large drill bit it must be slower or use coolant.my opinion.
Is that chuck on your dividing head a T.R .Almond?

+Tom Herd 50/50 I suppose

Yes-correct about the pilot drill.
I'll have to try your math.

Thanks for the info. That makes sense.

Great Video
Look like brake rotors.
