Re: Carbide Insert Speeds and Feeds

Not a dumb question at all. HR made holders for inserts that were precision ground. The holder in question accepts a modified triangle insert, ground with positive rake. Bear in mind, this holder is from about 1970, and I've been away from commercial machining since 1983, so I'm not up to date on wh...

Re: Boiler stays and heat expansion

I should leave this response to those who have expert knowledge, but the idea of having opposing flat surfaces not supported by stays makes no sense. Keep in mind, the pressure inside a boiler accumulates. It's measured as pounds per square inch--so if you have ten square inches and the boiler press...

Re: Rebuilding(?) a worn out lathe.

I don't know what things may need replacing, but the fact that the bed is flame hardened is in your favor, as a hardened bed is much slower to wear. The negative aspect is that it may not display wear in the way you might expect, forming ridges, for example. Wear may be gentle, over a long area, so ...

Re: Railroad supply switch Engine

Sorry, I'm no help with evaluating your engine, but I would like to make a couple comments that all readers need to consider. Please understand this message is not directed towards you, but readers in general. Posting pictures that large isn't well received by this board. It makes no sense to post s...

Re: Rebuilding(?) a worn out lathe.

Please don't condemn me cause I paint a lathe or whatever, One should not be condemned for painting a machine tool, as that decision is very personal, and can be done for the right reason. Some folks like their machines to look pristine, and there's nothing wrong with that. However, reckless use of...

Re: Does anyone recognize this lathe?

Perfectly normal. It takes a lot of experience for machines to be operated without error, but one should see improvement as time goes on. You get to the point where there's not a question about the end results---you know things will be correct, and when they're not, it's a total surprise. I used to ...

Re: Does anyone recognize this lathe?

I've told my story before, so I won't repeat it fully, but it's really important to have confidence in your ability. It took months for me to regain mine once destroyed. Sure was fun proving the superintendent wrong!

Re: Thinking of posting pictures?

What was the point of adding the auto resizing software then? The issue with pictures is multifaceted. Pictures are auto-resized by the software to avoid text spread . The reduced file size for the thumbnail is also faster to download. Readers would not be happy to have to scroll left to right in o...

Re: Thinking of posting pictures?

As I understand it (I'm open to correction if I have it wrong), while the displayed picture is resized, the original file size is still stored, so limited space is wasted on unnecessarily large file sizes. For that reason, pictures should be resized, including reducing file size. Not all folks do th...

Re: What is "Live Steam"?

The generic phrase 'live steam hobby' has expanded beyond only steam power. I believe he is wanting a definition of the generic phrase 'Live Steam Hobby'. I'm not convinced the meaning has expanded, as the name is very clear. Steam. One who is informed does not make reference to a diesel locomotive...

Re: Thinking of posting pictures?

Mike is trying to deal with the photo size issue, but he reminded me that resizing is all important , as the server doesn't have infinite capacity. If readers abuse the mandate to keep file sizes small, we risk having problems with the server shutting down. We can keep this thing running smoothly by...
