26-26-2018: Home Shop Machinists Podcast, Schaublin compound rebuild
A bit late, but another episode of the HSM Podcast has been released:
Home Shop Machinists Podcast – Episode 15 – Snowed, Towed, and Tooled

Also I did a rebuild on a Schaublin 102 compound slide for a customer, the process is documented here: Rebuilding a Schaublin 102 compound slide

I have a two part video series on the process too:

17-01-2018: Home Shop Machinists Podcast, Resizing a bearing race
Another episode of the HSM-Podcast was released, this time it was a full house. Not only Justin and Max, but also Max brother Thayer and father Fred and myself where guest.
Very fun episode to record, with some minor technical difficulties. We talk gunsmithing, Cad, current projects, cnc lathes, hope that Max can get into his shop in 2018 and much more. And cartalk.
Home Shop Machinists Podcast – Episode 14 – Phillipsed

For a customer I had to resize the outer race of a ball bearing to match the diameter of a router bit (woodworking).

Also important to note, there was another episode of the HSM-Podcast released:
Home Shop Machinists Podcast – Episode 13 – Have You Checked Your Oil?
Interesting discussion about lubrication of machine tools and Justin bought another machine, a Canadian made lathe.

I want to add one or two points regarding lubrication/maintenance and will do a video on that topic in the future.
As for providing oil to Zerkfittings, I found that a push-style greasegun works generaly ok with heavy way oil, especially the one made by Mato:
Mato PO 150-2 (Sorry, did not find a link in english.)

For the smaller type of oil-point with the ball I prefer a good oilpump like the Reilang which has no problem of creating enough pressure to get the oil past the ball and into the oil grooves.
