    Vactra or Vacuoline way oil?

    A couple years ago I bought a 16oz bottle of Vactra 2 for my mini lathe and mini mill. I've been using it since, but it wasn't as tacky and tenacious as I expected it to be. It's particularly annoying on the vertical dovetails of my mini mill. I've gotten into the habit of re-lubing the ways...

    Cutting down chipped end mills?

    So I now have a collection of 4 flute end mills on which a corner or two have been chipped. I figured I should be able to cut or grind the end mill shorter to get to the fresh cutting edge and keep on using them (obviously they wouldn't be center cutting). Is there any easy way to do this...

    New chuck doesn't fit new spindle

    I'm fitting a new spindle to my mini lathe so I can upgrade to a 4" chuck without an adapter plate. However, the register on the spindle is 72.02mm while the register on the new chuck is only 71.9mm. I can see the spindle register being a little oversized to allow it to be turned down once...

    7x12 metal gears

    If someone has changed both the 7x12 headstock gears hi-lo gears to the metal ones, would you mind telling me how much louder they are than the stock plastic gears? I'm replacing the spindle hi-lo gear with a metal one, and I'm trying to decide if I should replace the countershaft one with...

    New mini lathe spindle

    I'm installing a new 4" spindle in my mini lathe. Once it's installed, should I take a very light facing cut on the surface of the spindle to make sure it's square and flat?

    Machine covers

    I have a mini lathe and a mini mill I want to make covers for to keep the dust off when not is use. I haven't been able to find any pre-made covers, so I'm going to have to make my own. What is the best material to make them out of? I was thinking of using canvas.

    Heating up cast iron

    I'm going to be heating up an iron casting to install a bearing. It's the first time I'll be doing this. If I heat up the cast iron to 175*F is there any chance of it warping on me? My research says I'd need to heat it up a lot higher than that before it might start moving on me, but I figured I...

    New bearings for mini mill

    Since I'm already replacing my mini mill's spindle, I figured I'd replace the bearings as well. The stock bearings were painted over and are cheap no-names. I'd like to install good Japanese bearings like NSK or SFK. My questions are: 1. Do I need to get ABEC-3 or ABEC-5 bearings? Almost...

    Torque needed for MT3 drawbar?

    Pretty simple question: how much torque is needed for the MT3 drawbar on my mini mill? I hate doing things by feel.

    ER32 for my X2 mini mill?

    My mill has a MT3 spindle and I really hate having to hammer on the drawbar to release my tooling. Hate it. I'm currently using an end mill holder, which is ok, but there is invariably more run-out than I'd like. Since the X2 uses small end mills the run-out is an issue. A huge plus is easily...

    Low spot on milled surface?

    I milled a face on a 2.5"x3.5"x1.5" block of 1018 steel and a 3/16"x3.5"x1.5" 1018 steel plate. The two milled faces will be fastened together. I used a 5/16" HSS end mill at 1,100 RPM, 7"/min feed, lubricated with Boelube paste. When I checked fitment of the plate to the block I noticed a...

    Best way to match an existing diameter?

    I have a project I'm working on, and I'm not sure what the best way to perform this operation would be. Hopefully someone can tell me a better way to do it. I have a long shaft who's end have a 1" long bearing surface which rides inside a bronze bearing. I have welded an extension onto the...

    Indexable tool bits for mini lathe

    There seem to be two different indexable tool bit sets common made for the mini lathe: 1. http://www.grizzly.com/products/T10436 2. http://www.littlemachineshop.com/products/product_view.php?ProductID=1669 The tool bit shanks are different between the two sets. Sooooooo, which one should I...

    Plastic safe threadlocker?

    I'm working on a project where I have small metal screws going into nuts embedded in a plastic body. I don't want to use a normal threadlocker like the blue Loctite since I won't be able to keep it off the plastic as I assemble the two parts. I've done some research into plastic safe options for...

    Using shims to tram a X2 mill

    My mini mill has the LMS solid column and base, where the column is attached to the base via bolts at the four corners. I use shims between the column and base at the four mounting bolts in order to align the column. I'm currently using feeler gauges as shims. They are 0.5" wide and I always...
