    Costing you more money! Also unnecessary on a manual machine. The high angle isn't necessarily as high as you assume, there are different edge prepa for different materials, the same as all the newer...

    You might want to look into an SEKN or similar if you're doing a lot of heavy material removal. I've always found them to be about the best roughing insert there is. The high lead angle means you can...

    A lot of the videos on Youtube seem to be of trains running with leaky exhausts or missing mufflers but this one gives a pretty good representation of what they should sound like I think.

    Every one I've worked on has been a close slip fit. At that size I'd probably shoot for whichever tolerance level gets you to .0005"-.001" clearance.

    Well, let's hear what exactly he plans to do first. Next, are you the owner of that tooling or just a fellow employee or supervisor?

    Rensselaer is about 30 minutes from me. Never knew they made miniature trains there back when; pretty cool.

    Yeah this is a complicated subject without just one simple answer. To find out the true cause you'd need to check a lot of the geometry of the machine. Generally if you have a bed wear problem you...

    Coolant is your friend, no two ways about it. Especially so when you don't have a helping hand from a magnet. It's slow going without coolant. Cutting your cross feed and using even a spray bottle...

    I take it the belt is for longitudinal table travel? I said a few choice words when reinstalling the one on my MicroMaster for the first time that serves the same function. They definitely have some...

    Not wildly overpriced, but not cheap either. I guess a much more solid machine than most of the micro size machines though.

    That is true, and those are easy to tweak also...;) A lot of the larger shops I worked in wouldn't bother tweaking the machines either. They'd just tell you to bump the tool if there was a taper.
