**Home Shop Machinists Podcast – Episode 13 – Have You Checked Your Oil?** Dec 03, 2017
Show notes

After over a one month hiatus, Max and Justin are back with episode 13!

Some of the things we talk about include:

Max has had limited time in the shop. What does work always get in the way of what we want to do?

Justin purchased a sub $200 USD digital read out from eBay. He calls it the Shenzhen DRO. And so far it has been pretty good.

Justin’s new lathe – a Standard Modern 12×30 Utilathe. It was terribly dirty.

Which leads us into maintenance. Why do so many people neglect equipment?

Max goes into the wonderfully simple cone style plain bearings. Keep it clean and adjusted!

Bearing preload

How do you keep track of all those oil points?

The importance of way oil

Chuck lube. Let the debate begin. Max and Justin like getting sprayed with oil apparently.

A live stream episode with Stefan Gotteswinter and Robin Renzetti? Let us know your thoughts!

All that and a few tangents (would it be a show without a few?)

Home Shop Machinists Podcast – Episode 11 – Shop of the Future Oct 02, 2017

Show notes

In this episode Max and Justin decide to prognosticate about what the home machining shop of the future looks like. 50 or 100 years down the road is it going to be full of modified CNC machines, or will the electronics on those machines render them scrap and only the old school manual machines still be in use? We talk about

Max’s sea foam green stamping fixture
Max is working on a new TV stand for the house
Justin finished his tailstock tap and die holder
A new mill drill for Justin’s shop. Did he make the Rong choice?
The Dodge Omni and Shelby GLHS
Do all VW owners hate Honda owners?
Max’s hatred for all things Digifant
Laser bandsaws
Motivated millennials: will they keep CNC machines going?
Are we living in an golden era for home shop machining?
Will the cheap tooling end?

All that and much much more!

Home Shop Machinists Podcast – Episode 9 – We Are Finished! Aug 16, 2017

Show notes

In this episode Max and Justin talk about finishing and both agree that they are terrible at actually finishing projects. In fact, it is amazing that this podcast is still being recorded and not sitting on a shelf somewhere collecting dust waiting for completion. It did actually sit for about a week until Justin managed to finish the editing! In this episode:

Justin finishes his toolpost for the Schaublin 102 and now is onto making proprietary arbors for the tailstock. Why do watchmaking lathes seem to always use proprietary tooling? (Max’s Rivett is no exception)
Max made a quick and dirty ER11 collet holder for the Hagar mill. https://www.youtube.com/watch?v=OHO_IefxoA8
Stefan Gotteswinter is mentioned numerous times.
We talk about the cool planetary backgear setup on the tiny Craftsmen 109 lathe, its only redeeming feature.
Max’s hand wheel for his Rivett: http://joyofprecision.com/post/124430721351/replacement-cross-feed-handle-for-the-rivett-8 http://joyofprecision.com/post/124431412156/replacement-cross-feed-handle-for-the-rivett-8 http://joyofprecision.com/post/124431554281/replacement-cross-feed-handle-for-the-rivett-8

As usual after about an hour into it we finally get to the topic du jour: finishing. We look at all sorts of angles but find ourselves looking forward to the next podcast guest!

**Home Shop Machinists Podcast – Episode 8 – G’Day Mate** Jul 21, 2017
Show notes

In this episode Max and Justin take a trip down under, and back to the future, and talk with John Creasey, an avid home shop machinist from Australia. As usual the discussion topics vary considerably, but we do talk a bit of machining. In this episode you’ll find:

John and Justin get a little teary eyed over the Queen. Don’t worry – we don’t break out in God Save the Queen

Australian politics: the laws of mathematics are no match for the Australian government!

John lets us know he has 2 Myfords. His first was purchased by his father when he was 16. Let’s here it for great Dads!

Electric cars, VW Vanagons, and taking things apart when we were kids

We talk about scouting, ripping out hard drives, and rip apart day

Stefan is mentioned numerous times

Did Max forget to empty his shop dehumidifier?

Arduinos in the home shop: Edu Puertas (stop motion) https://www.youtube.com/channel/UCdEtDnvVeoqlKzpquM7IsNA and the Arduino lead screw https://www.youtube.com/watch?v=BaBK9teKUaA

All that and much much more.

**Home Shop Machinists Podcast – Episode 7 – Work Holding** Jul 04, 2017
Show notes

In a first for us we manage to get an episode recorded, edited, and posted in about 2 weeks! Don’t worry we didn’t skimp on the quantity of the recording – this episode is a long as the rest of them (note nothing was said about quality!). In this episode we talk about work holding and tool holding in general. Apologies for our voices – we both were recovering from colds. Highlights include:

Max gets his turret finished just in time for Emma’s tool making competition: https://www.youtube.com/watch?v=xe3ACUzET7Y Check out the pile of chips on the watchmaker’s lathe:

Justin is inching (what is the metric equivalent?) towards getting the Schaublin 102 up and running.

Someone opens a beverage. Identify the time and send Justin an email: justin@thecogwheel.net to claim your prize!

Justin is recording in the middle of a terrible thunderstorm.

2 Jaw independent chuck? We talk about one:

Justin and Max are big fans of ER collets. Maritool is a great source for production quality stuff at reasonable prices.

Stefan Gotteswinter gets his mention.

Use your 3D printer, or a 3D printing service to make soft jaws for your vise! Or a fixture setup for your face plate.

Clamping nuts – we don’t know what they are called but Max made up a set of them. Identify them, send Justin and email justin@thecogwheel.net and claim your prize!

Max thinks Justin should build some die holders with driving squares in them like these ones:

All that and much much more.

**Home Shop Machinists Podcast – Episode 6 – All Scraped Up** Jun 14, 2017
Show notes

Despite our terrible bantering in episode 2, Stefan Gotteswinter decides to come back on. Max and I think perhaps he might be suffering from poor judgement. In the longest episode to date we talk about:

Stefan’s 1200 km drive to take Richard King’s scraping class and he lets us know some of what he has learned https://www.youtube.com/watch?v=pO9GW0tAOIQ

Push or pull scraping?

Justin still can’t get over Stefan having Japanese power tools. Isn’t there a law in Germany against this?

We talk about Bosch

We talk about machining titanium

Max is busy working on his turret for Emma’s tool making competition: https://www.youtube.com/watch?v=W_VHt6j_xtw

We talk about bearings

And there might be some beer talk. Wrong podcast. Again.

Home Shop Machinists Podcast – Episode 4 – From Grass Cutting to Space Mar 24, 2017

Show notes

Max and Justin invite Dan Sherman on for some general shop talk. We started talking about what is going on in the shop but in true home shop machinist fashion this episode heads off on several slightly off topic tangents. Within this episode:

Welding and machining, is it a left brain right brain sort of thing?
Justin gets a Schaublin 102 for the home shop!
Max trams his mini mill with epoxy. Would this be an episode without mentioning Stefan? Tramming a mill with epoxy: https://www.youtube.com/watch?v=U7Qs-J2swIc
Max’s pinion mill is coming along: https://www.youtube.com/watch?v=qPUKtlsjPRA
Dan is building camera mounts: https://www.youtube.com/watch?v=4RtZOJ7f2LE
We all wonder what normal people do with all their time since they don’t fix anything and don’t spend all their free time in the shop. We are really starting to sound like old farts.
Bench grinder balancing with a cellphone? Dan is interested and Justin has a shameless plug to his blog: https://thecogwheel.net/2016/07/06/bench-grinder-balancing-with-a-smart-phone/
The Davenport screw machine. Yes, you can still buy one! http://davenportmachine.com/
Check out the documentary Moon Machines on Youtube (https://www.youtube.com/playlist?list=PLTu8nanTJo7GvulBxz9JT9JcXeXimM1Vr) and When We Left Earth: The NASA Missions on Amazon https://www.amazon.com/gp/product/B0085E40F4/
We also talk reel mowers, grass cutting, steel, surfers helping with the space program, the SR71 Blackbird, Koenigsegg and probably some stuff in between.
