Re: BIG bed planer

LOL, you might be pretty close, set the cut and go for a long lunch at least. From the details I've run across over the years even getting the proper foundation in place for them is a massive and very expensive task. At those lengths the curvature of the earth makes standard machinist levels slightl...

Re: BIG bed planer

12' long would be considered a small one in some industry's. Huge to try and shoe horn that into a home shop though. Afaik there were at least 3 types. The dual vertical column machines like the first picture, an open bed classed machine that had the single column like in the second picture for doin...

LOL, in other words for now I'll side step it's tool eating habits. :mrgreen: A whole lot of our mill parts got sent out to specialty ...

Re: Steel plate identification

It's used in the haul truck boxes as well Bill and I suppose during a lot of large bucket rebuilding. I've got some plate cut offs that were used as OEM Cat haul truck box liners. Haven't quite dared to go past the thinking about machining it though. If it's AR 500 as I suspect it might be that mate...

Re: Starrett #123 26" Vernier Caliper

For me it's practicality, having to use a magnifying glass to even read it for a measurement that's still of less accuracy than a mike doesn't have much appeal. And yes I do know out of the 3 types the vernier if it's well made will almost always beat the other two for accuracy and longevity of it's...

Re: New guy with a new used mill lots of questions.

You can of course bore the diameters to fit your indicators if you have boring bars small enough. Most won't have bars that small. So it's a good idea to drill then ream to size to fit the indicator stems. The Starrett or Mitutoyo online catalogs will give you the best design ideas for what your nee...

Re: Vise Squad

100% agree John, I don't knowingly abuse any tools I own. My 5" Record bench vise made before they went off shore has held everything I've needed to hold or press parts together without noticeable flexing, breaking a single part of it or bending the handle. It's more than strong enough for it's size...

Re: New guy with a new used mill lots of questions.

4 flute end mills would be when making larger width cuts than the end mills diameter, two flute when cutting something like a keyway where maintaining a specific width is important. I'd suggest generic cheap end mills when your starting out, better and more material and job specific coated end mills...

Re: New guy with a new used mill lots of questions.

Edge finders as you've found come in various types from this https://www.amazon.com/Starrett-Edge-Finders-Single-End/dp/B007K35KAU which should be a good one, the ones with a point are mostly for picking up center punch marks or small holes, to the electronic type which won't work on non conductive ...

Re: New guy with a new used mill lots of questions.

The one rule about machining that needs to always be remembered is that rigidity is everything in the tool holding and part set up. Machine mass would be just about as important. If your spindle is R8 then proper R8 collets will move any cutting tool up and as close as possible to the spindle bearin...

Re: The home shop machinist, health of the hobby

I'm old enough that when I went to high school the first year we had to go through metal working, wood working, drafting and electrical. Those weren't optional, but after that you could then chose what was of most interest. So fortunately I got that experience and metal and to a far lesser degree wo...

Re: New guy with a new used mill lots of questions.

I could be wrong but some of that tooling appears to have some type of quick change system machined and ground into it. What spindle taper does your mill have? If I'm right you'll need the male adapter that fits your mills spindle taper that also has the female socket to hold the quick change toolin...
