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:
After getting confused as to what podcast they are recording, Max and Justin talk about hauling machine tools home. Of course the stories keep getting better and more ostentatious the more they are told. We also talk about:
Max’s work on his Trent Pinion mill
Change gears on the lathe – you don’t need that 127 tooth to cut metric threads all the time. Max finds a really well done gear calculator on the internet: http://geargenerator.com
Justin gets a Delta Rockwell surface grinder for the home shop and tells the story about dragging it home in his father in law’s truck
Max can’t be outdone: 7 Hjorths, an overloaded van, pouring rain and a flat tire
Any other Hjorth owners out there? Send us some info!
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?
If you are depressed about what is in the news just listen to this podcast and you won’t have a chance to listen to the news again! In the longest episode to date Max and Justin talk about 10 tools that we find essential to our shops. Buried within this episode:
As usual Justin forgets to edit something out that Max says
Max tells us more about his Trent Pinion Mill that arrived from the UK via some sort of beaming machine
Gearotic and Max’s Orrery build (say that without sounding intoxicated!)
Why the Brits put the carriage wheel on the right side of the carriage
Maintenance on cars, 3D printers, and terrible instructions
Max tells a joke
Fecal material on cell phone screens
The 10 tools in the shop that we find useful … which turned out to be 8
It’s been more than a month since our last episode where we said we would try to record an episode 2 times a month. To make up for it we snagged Stefan Gotteswinter for an interview. Thankfully he hung around long enough to answer our questions and didn’t seem to be too put off by our antics. In this episode
Stefan is looking at Onshape.
Max geeks out over Wine for Linux (sorry) and thinks you can easily run Autodesk’s Fusion in Linux.
Max gets a Hemingway kit, the Trent Pinion Mill, and now he has to machine it!
Chinese machine tools really are not that good, but are great for home shop machinists!
Stefan suggests to think of most imported machine tools as casting kits.
How to get banned in less than 5 minutes on Practical Machinist.
Germans have a lot of home shop machinists, who mostly use CNC. Germans and their tech!
Stefan uses carbide in the shop. We’ll make him listen to our first episode again before we invite him back on.
Stefan would be happy on a desert island with a Deckel FP1… and all the accessories. Who wouldn’t?
Max happens to think German is an eloquent language.
How could you interview a German and not ask about beer?
Plus a whole lot more. We managed to trim 10 minutes off this time to get our 1 hour podcast down in 1 hour and 20 minutes!
I decided to start the New Year off by making some small productivity improvements in the shop. One of the things I find myself constantly doing is reaching for a wrench to tighten the tool post, and also the tailstock (more on this soon!). I decided to make a tool post lock nut and handle.
From this point on I’m going to try to make drawings for all the projects that I do in Autodesk Fusion. I’ll also share the CAD data in Fusion once I get that setup. Below are the drawings for each of the parts:
In the video I talk a little about the taps I primarily purchase and use in the shop. YG’s spiral flute bottoming machine tap is my go to tap. The quality on these taps is exceptional, and work well in many materials that you find in the home shop. They are designed for tapping blind holes, but work equally well in through holes so to keep costs down I try to just purchase these. Avoid the cheap import sets for thread cutting. Usually these sets are made from high carbon steel (not high speed steel), and they generally do a poor job in the shop.
If anyone says you can’t tap properly by hand using machine taps, they probably aren’t using good machine taps, or need more practice I guess. I find that the YG machine taps are easier to use and start than standard hand taps and do a much better job on the thread. Let them pick out the broken hand tap.
