Making a boring head.
« on: March 31, 2013, 09:56:37 AM »

Needed a boring head and decided to make my own as explained in "Milling a complete course" by Harrold Hall.

Pretty much followed the instructions and sequence in the book.

This was a nice project to learn more advanced skills and I am very happy with the outcome.  Had the opportunity to use the boring head on another project and it works perfectly.

Cheers to all.

Great to have this, Abraham. Thanks! Coincidentally I had sent for the Harold Hall book a couple weeks ago -- hasn't arrived yet, but that's one of the projects I was interested in.

Wow, nice work. Both the job and the explain.

That is a hefty piece of steel you have there, that will smooth out the cutting too. Great.

Personally I would break the corners a little more, they seems sharp.
But, talking about sharp, great dial you made there, very clear markings. You have convinced me that I need to start thinking about an indexer on my lathe too, it looks very well done.

Ah well, plans and plans and plans and....
