call for instructors for classes

Hi All,
I’d like to get some more classes on the books for October/November. Without volunteers, we cannot run classes. Without classes, people could use the tools incorrectly damage the machines or injure themselves. Remember, the Hive is a Do-ocracy!!!

I could use some volunteers to teach the following classes. It doesn’t have to be a formal presentation. Don’t be afraid to try to teach one if you think you can! Also, you don’t have to teach a class by yourself - feel free to teach part of one! I am hoping to get at least another 2 events scheduled in October (I know we have the makerfaire and books by the banks, but still!) and another 3 events scheduled for November. Elly has already volunteered to do a class on the laser cutter in November and Bill has volunteered to do the second tuesday talk in November. But there are lots of open days!

Breaking these down into areas of the hive we get:


  1. An introduction to traditional woodworking - introduce those new to woodcarving primarily using traditional mallet and gouge techniques. Instruction will tool safety, how to work with wood grain and tool handling techniques.

  2. An introduction to the woodworking tools at the hive including shop rules and general expectations, and wood working safe/best practices. Major wood working tools will be covered, including use of the jointer, thickness planer, scroll saw, table saw, wood mini lathe, miter saw, sanders, and any other equipment I am forgetting.

  3. CNC router training - something perhaps similar to how Dallas makerspace does their classes (an intro to the machine and then another one where you run through it)?

  4. Basic CNC Router is approximately 4 hours in length, and has a $50 fee. This fee helps pay for replacement bits and machine maintenance. After the class, a hands-on test must be scheduled before unsupervised use of the machine is allowed. This class enables users to cut wood and products made from wood.

  5. CNC Router Hands-on is a workshop intended for new users to get some additional hands-on experience prior to taking their test for the Basic CNC Router class. The class is limited to 5 persons. (this could perhaps be done after a tuesday meeting, prior to the actual class).

  6. Using the Shapeoko - perhaps another thing related to the CNC classes?

Metal Area

  1. Introduction to metal working - theoretical discussion and introduction to the various metal tools we have at the hive. Could be after/before a tuesday meeting.

  2. Using the Mill and the Metal Lathe - I know Brad Walsh said he would teach this class, but I’d love to hammer down a date and time. Would expect members to have gone through the intro class first

  3. Welding class - we have a MIG, and possibly a tiny TIG? how to pick the right welder for the job. differences between the welders we have and other options.

  4. Along with this I would expect the students to learn to use the bandsaw and the angle grinder.1. Introduction to casting

Electronics Area

  1. Electronics Workbench Orientation Class - Learn the roles of our electronics workbench equipment in testing and developing circuits.

  2. Soldering - the types, how to pick the tip for the job, what solder to use, etc

  3. Introduction to circuits - explain resistors, capacitors, etc. Maybe wire up some basic circuits.

  4. Microcontroller Introductions

  5. Raspberry Pi – we’ll take a look at loading on an OS and connecting it to input and output devices. Run a few basic programs etc.

  6. Arduino – we’ll take a look at booting up arduino and connecting it to input and output devices. Run a few basic programs etc.

  7. Connecting the dots - connect an Arduino to the Raspberry Pi and load a few simple programs on to it. We’ll also discuss how to tap in to the vast amount of online resources that will prepare you for infinite creative possibilities with these two amazing devices.

  8. Make your own d*mn boards - learn the basics of PCB design and about creating printed circuit boards.

  9. Basics of lockpicking

  10. Introduction to programming - this one could be very open-ended, maybe classes in the different languages? resources and links to where to learn to program, etc. How do you know which code to pick? etc

  11. Introduction to the sewing machines/serger/embroider at the hive which would include threading the machines, winding bobbins, picking the right stitch for the job and sewing straight lines, and basic sewing techniques.

Fab Lab

  1. Designing 3D models, how to pick the right software, etc. (we did just have this class, but would like to schedule it again for Decembber/January)

  2. Introduction to 3D printing (theoretical) - discussion about the different filaments/nozzles/machines etc

  3. Using the 3D printers at the hive (hands on) - walks through the different 3D printers we have at the hive, how to use them/home them/stop them/etc. and any special considerations for the individual machines. Users will print a hand to support the ongoing project at the hive.

  4. Laser Cutting at the Hive - Elly has volunteered to hold a class for this in November

In Summary - please, please, please consider teaching a class. I will be in contact with other people outside the Hive to try and get some experts in for things. But we need YOU to step up and teach some classes. and we need you to ATTEND the classes! Email me if you are interested in teaching a class at this email or


I would be happy to do the Intro to Metal Working, Mill and Metal Lathe classes.
While I am the CNC/machining warden I do not have very good CNC skills so I would be very interested in taking the CNC classes. (I can help run them) :grinning:

With the Cincinnati Maker Faire coming up Oct 7th, why don’t we propose October 22 for a Mill and a Lathe class, back to back. Something like Mill from 10:00-12:00, lunch break, Lathe from 1:00-3:00. I can provide a link to get an inexpensive cutter for the mill (around $20) and the lathe tools we have should be fine for a class. I like the idea of people having some “skin” in the game rather than a totally free class. Perhaps they pay for the metal pieces they are working with?
We could buy some stock (Aluminum) and them charge them to cover the cost.

Brad i will donate those 2 smooth gun barrel blanks for your class if you would like…I’m not using them on anything lol they are to short and modern for the Kentucky rifle/ muzzle loader I want to make this winter.

Tiff I will get with you on dates to combine metal working classes the same Brad is. Katie keeps my schedule so it will take me a few days to figure it out.
There was talk about getting sheet metal equipment brought down to the hive. If that is coming it can be integrated.
I have also come up with a very successful waste oil heater for a forge or pretty much anything with shaping , tempering , treating, and melting. The small prototype I made runs off of used motor oil from Cars and burns at such high temperatures it doesn’t leave any of the thick black smoke or other things that go along with oil burners, it is extremely clean to use. I have already used it to melt down some thick aluminum car parts so it should be interesting and cheap to use. The only thing we will have to do is buy some longer air hose extensions as I need compressed air for the oil misting jet.

I will also of course get the welding classes together.

Hi Tiffany,

I’m new but have experience with CNC and 3d modeling. If someone could help me get acquainted with the Hive’s router, I would be happy to put something together.
I’m sorry I missed the past 3d modeling class, but I could volunteer to do a class on that as well. My software of choice is Rhino, I know we don’t have it at the Hive but it is a very robust and affordable option. I am also good with Sketch-up and could look into other software if they were in demand.


I’d like to do a series of electronics oriented classes which will build on each other. Someone with prior experience would be able to skip around but not someone relatively new.

  1. Circuit fundamentals - AC, DC, resistors, capacitors, basic semiconductors. The whirlwind tour of electronics, lots of pointers to further resources

  2. Circuit board design and design-for-manufacturing i.e. taking an idea, identifying key specifications and then what to look out to when actually trying to make a board. Dos and Don’ts for etching your own vs. boardhouses

  3. PCB design tools (I can teach Eagle, Jon Neal can teach KiCAD)

  4. Basic soldering using an iron - through hole and surface mount
    4b. Basic desoldering using a vacuum-assist iron, desoldering braid, hot air

  5. Advanced soldering without an iron - solderpaste, stencils, hotplates, reflow ovens, hot air

  6. Test equipment 101 - meters, scopes, bench power supplies

I figure each one of these topics is easily an hour - 2hr class.

I’m thinking that a “simple” but non-trivial project that would track through the various classes would be a good way of grounding (no pun intended) things in the practical, real world. I was thinking something along the lines of a full bridge AC-DC power supply with current limiting and an arduino/Teensy doing PWM control / monitoring / feedback.

Ambitious? yes. Within reach? sure. I know Lorin will help where he can. I hope others with some expertise will too. I can start in October. Welcome feedback from membership about how to do this in a way that is most effective. Tuesdays are OUT for me due to work conflicts with my wife. Weekly class on another day? Biweekly class on another day?

-Dave B.

Go for it Dave. I’ll help out. I can’t commit to October – too much up in the air. I’ll get the new upgrades rolling in so the bench is more functional.


I dropped of a 555 timer kit that I soldered up. It is super cool because you can tap into the various circuits and see what is happening and how the different resistors/capacators change the timing.

Feel free to use that for any classes.

Found a nice carbide 3/8" end mill for $6 on amazon.

It would be a good one to make part of the class. We could order a few and get some Aluminum pieces. I’ll dig around.
American Metal has a remnant area where you can get some nice chunks/pieces at a $/pound rate (min $40 order though).
Maybe we can get a small budget setup and get the supplies for a class?

Keep in mind that Garden St. next door will sell you anything on their scrap yard for twice what they pay for it (scrap value). I’ve scored some very nice pieces of stuff that way. May be worth a stroll if you make it down during business hours.

Just bring gloves and make sure you’re up to date on your tetanus shots.

I’d be willing to teach a class. I’ve got the following areas:

  1. Basic wood working, maybe a single tool, I’d like to keep it down to about an hour, and I think the whole shop would take much longer.

  2. Intro to programming. I know the following languages (and can figure out the rest): C/C++, Java, C#, Javascript, PERL. Javascript might be the easiest for new people to pick up. It also occurs to me that there are probably a LOT of people at the hive who know this area.

  3. Intro to miniature painting. I could give a quick tour for people who are interested in painting DnD or miniature wargame figures. If there’s interest I could follow up with an advanced class some time next year. I’ve also got an air brush, and a little skill, I could probably teach people enough about airbrushes to be dangerous.

Right now I’m leaning towards miniature painting, since it might be a more unique skill than wood working or programming, but I also realize it doesn’t necessarily cover things at the hive. Since you’re coordinating, and have a better understanding of interest levels, please pick one. I’ll get back to you with details.



All three of those would be something I'd go for, especially since I have little experience in any of those areas but have been meaning to learn all of them to a degree. The miniatures painting idea sounds really cool, although I'm not sure what a class on that could entail.


I was thinking some basic coverage on what is needed to get a model from the blister packaging onto the table with the least amount of fuss.

Basic Painting

And the tools and techniques necessary to do those things. I’ll give some thought to the time and get back to you with a date.

Thanks Andrew! The miniatures class sounds great (as do the other two!)! Let me know when will be a good date. Possibly sometime in November? What supplies would you need ordered ahead of time? or would you have them bring their own?

I was thinking about just doing a basic slide show, so no supplies. Give me a couple of weeks to whip up a power point. If you think it would be better to go interactive, I can provide paint and minis. We could also do it as a 1-2. Intro slide show first week, interactive muck about next week.

Andrew, I could use some help with my airbrush technique. I have an airbrush. Just FYI.

Is there interest in a basic old school Unix/Linux command line class?

It might be neat to bring in an old Unix box (Barry, I'm looking at you :smiley:
) of some kind for folks to shell into and navigate, or maybe to use SDF
for the ultimate old school experience.

I’ll keep it in mind. Might also be interesting for people who are on the fence about buying an airbrush. I could easily see doing a series of classes for this, basics, advanced painting, airbrush. OTOH, I’m far from an expert on airbrushes, you might end up teaching me something. :wink:

Tiffany, please pick a date for me to present any time that’s open two weeks from today, at 8, after the Tuesday meeting.

Class title:
Assembling and Painting Miniatures for the complete Beginner

Learn to assemble and paint miniatures from a variety of manufacturers. This will be a simple presentation covering the basics for people who are curious about getting into the fun and rewarding hobby of painting and assembling miniatures. It will be a short talk covering tools, techniques, and pros and cons of various approaches. Students will be expected to have no experience with the topic at hand. A follow up talk will be schedule to detail more advance painting techniques including airbrushes aimed at more experienced students.



I would be interested (as I mentioned before ducking out last month!) in doing something with an intro to the CNC router.
How to get together to discuss class format, contents, scheduling etc?
