Re: Questions about new DRO

Interesting idea.
There is a possibility you will lose some resolution/repeatability due to the extended mounting.
It provides opportunities for flexibility, especially if hit.

Re: Annoying Movie Welding

Fortunately there are occasionally well-researched movies. "2001: A Spacey Odyssey" being one. Kudos for that. As for the Einstein quote: "Imagination is more important than knowledge." I had that posted on my office entrance (decades ago) when my boss came in and asked: "What kind of idiot said tha...

Re: Spark arrester design

When we rebuilt the 90-ton Climax Hillcrest Lumber #10 in 1982, The Boss insisted we install the Radley and Hunter stack on the new smokebox. It was TERRIBLE, causing big steaming problems due to the poor drafting. We could not produce sufficient steam to get the light locomotive up the grades. And ...

Re: Questions about new DRO

I have glass scales on my lathe, and magnetic scales on my milling machine.
They both seem to perform identically, as far as resolution and repeatability.
I prefer the much more compact nature of the magnetic scales. Easier to clean if necessary, too.

Re: Allen Models - running boards back in stock

Harold: Can you set up a separate discussion on Tolerances or perhaps even better "Allen Models Drawing Updates" and transfer the subjects above to that title? This is important enough to be a searchable item for future reference. And it has "polluted" Mikes original note on Allen Runnings Boards no...

Re: Allen Models - running boards back in stock

Harold said: "One knows, at a glance, if a dimension is critical, or not, and if so, how critical." That may not be true for the beginning machinist. Mike's comments on the original Allen drawings are spot on. When I began to build my Ten Wheeler 20 years ago, I had to carefully study each part, ide...

Re: Allen Models - running boards back in stock

Well done. Those castings are difficult to make successfully. Different subject: Are the drawings for the Mogul, American, and Ten Wheeler being updated to correct the Link hanger pivot location? It needs backset for equal operation in forward and reverse. Drawing attached showing this correction. I...

Re: Track Standards

I would expect that no super elevation will be your goal.
With your tight radius curves, and low operating speeds, there should be no need for it.
I can just picture that high speed run through your woods...
