boring head

This post is about making some very rigid holders for indexable inserts for use with Criterion style boring heads. This is a Criterion boring head with a typical set of low cost sweated carbide boring bars. A genuine Criterion like this comes in at around US $5/600 for a 2" version, but...

At a recent auction I picked up a Dake #1 Arbor Press as an upgrade to my Dake #0 that only saw occasional use, but at least once I wished I had more capacity. The price was right, after fees/taxes it came out to $100 - but this thing has definitely seen its decades of use in production. I...

Having purchased 1 of these & sourcing information best i could, these are the best instructions & details that I'm aware of. If you have more to add, please do share.

So as you can guess I would like to get a boring head. It will be used on a PM-727 mill. Is there an appropriate size based on the mill size? Also if you could have only one boring head what would be the most useful size. Speaking of size I am working under the assumption that a 2 inch one is...

This is the only piece of information on Chandler-Duplex Boring/Facing heads that I've been able to locate over the years. The Company no longer exists. As far as I know there is no source for replacement parts. I do have a few N.O.S. parts on hand that I intend to revere engineer and...

Hi all, just joined the forums, and I had a question for other Criterion boring head owners out there. I just picked up a Criterion DBL-203 3" boring head on eBay. It appeared to be in excellent condition, so I went for it, and when I put it in my mill, it looked a little off to me. So I got...
