Plans, projects and how-to's for home machinists

Digital Machinist CNC Workshop – June 22-25 in Ann Arbor, MI

I just found out about an inexpensive CNC Workshop for hobbyists that is going to be held in Ann Arbor, Michigan from June 22 to 25, 2010.  I’d really like to go because I recently acquired a CNC mini-mill, which I haven’t learned how to use yet because it’s either been buried by building supplies for our home remodeling project or it’s just been too cold to spend time in my garage.  The workshop has some great topics, very inexpensive lodging is available if don’t mind staying in a college dorm room and the workshop only costs $150, which includes a BBQ on Friday night. (You can save $25 if you hurry and register by March 15th)

Unfortunately, it’s about 400 miles from my home in Rochester,  New York, and I’ve already made two long trips to home machinist shows this year (Cabin Fever & N.E.M.E.S).  I don’t know if I want to make another long drive by myself.  So I’m looking for someone who might want to go at least part of way with me.

The workshop is sponsored by Digital Machinist magazine.  Here’s a list of the seminars, with more expected to be added later:

  • Adventures in Homeshop CNC
  • Basic Multi-tool Operation in Mach3
  • CAD and CAM Alternatives – From Free to “You Probably Can’t Afford It”
  • Cheap and Easy CNC
  • CNC for Model Making
  • Decorative Design and CNC Machining
  • EMC Labs
  • Emergency Stop Circuits, Mains Disconnect, Motor Contactors, and Fusing
  • Getting Started in CNC
  • Grounding, Shielding, and Isolation – Safety and Noise Issues
  • Hands-on CAM Workshop
  • How Things Move
  • Machine Tool Manufacturing in China
  • My Quest for an Inexpensive Desktop CNC Tool Changer
  • Reverse Engineering with a CNC Scanner
  • Spindle, Servo, and Stepper Motors – Their Properties and How They Work
  • What Makes a Machine “CNC Ready”
  • Wiring a Low-cost Electrical Enclosure
  • Writing Mach3 Wizards

There will also be vendors there.

2010 Cabin Fever Model Engineering Show

This photo shows only a small part of the Cabin Fever 2010 Model Engineering Show in York PA. I couldn't find a good vantage point where I could take a picture that would show how big and well attended it was.

Last weekend I attended my first model engineering show, the 14th Annual Cabin Fever Expo in York PA.  It’s a three-day event but I was only there on Saturday, which is when most of the exhibitors are there and when most of the seminars are held.  The show is one of the largest of its kind and I had a good time.

I think any kind of modeler would be welcome to exhibit their work at the show, but it’s dominated by those who make things from metal.  So many of those who come to the show are interested in machining and metalworking.  There were also many there who were interested in live steam.

There were dozens and maybe hundreds of steam, internal combustion, Stirling and other engines on display.  Actually, they weren’t just on display.  You could see most of them run.  The organizers provided compressed air for the steam engines to run on and the internal combustion engines were allowed to run on small quantities of fuel (lantern fuel I think because it burns cleaner and produces a more pleasant smelling exhaust).  The Stirling and other hot-air type engines were usually powered by candles or electrical heat sources.

There were a lot of trains, especially steam-powered trains.  They could be found in all sizes, including some that were more than ten feet long and looked they weighed hundreds of pounds.  There was also a lot of track for them to run on.

Some of the boats and the huge indoor tank at the 2010 Cabin Fever Model Engineering Show

If you’re into model boats you would not have been disappointed.  Not only were there plenty to look at, but you could watch them run in an absolutely humongous indoor tank they constructed for the show.  Again, many of them were steam-powered.

There were other kinds of models to see, like cars, guns and miniature machine tools.  Most of the exhibitors were showing things they built themselves.  But there were others who were showing things they collected or restored, like old model airplane engines.  There were also demonstrations going on throughout the building.  The one I found the most interesting was Ron Ginger’s demonstration of Mach 3 and a CNC router that he recently designed and built.  Ron also led a seminar on CNC and I learned an enormous amount from him in just a little while.

The show’s organizers make it very easy to be an exhibitor and you won’t feel out of place if don’t have something fancy or unusual to show.  You just have to pay the regular $10 admission price and tell the ticket seller that you have something to exhibit.  In additional to table space and a chair, you’ll get some name and description cards for your exhibit, a chance to win door prizes, and an invite to a meet-and-greet reception after the show on Saturday.  By the way, the $10 admission fee was good for all three days and there was no charge for children under twelve.

There were also at least fifty or sixty vendors selling metalworking and woodworking tools, models, kits, plans, parts, castings, books, services and many other things, both new and used.  Many of them were selling used machine tooling and measuring equipment at good prices, but I didn’t buy any.  It was partly because there’s not a lot of things I need, partly because I’m pretty picky when I buy used stuff, and partly because most of the used tooling was too big for my mini-lathe and mini-mill.

There were also vendors selling new tooling and equipment, but not as many as I was expecting.  I was a little disappointed because I had stopped at the Grizzly Tools showroom near Williamsport on the way to the show and had been really tempted to spend my money there.  But I didn’t because I thought I’d find lots of good stuff at the show.  I didn’t and I couldn’t go back to Grizzly’s because they’re closed on Sundays.

A big steam engine and tender. There were even bigger ones at the show, and much smaller ones also.

I did buy some metal.  Of course I regretted not buying more after I got home.  It doesn’t spoil, prices are likely to keep going up, and I think it’s a good to have a large assortment on hand.  The vendors were selling mostly brass and aluminum cut-offs, but the prices were good and one vendor had a large assortment of large diameter rounds and big blocks in sizes that were perfect for things like large flywheels.

There was also a lot of train stuff for sale but I can’t tell you much more than that.  I know model trains are popular and live steam ones are particularly impressive, but I’ve just never been interested in them even though I come from a family of railroad people.

I didn’t get a chance to see much of York while I was there or learn very much about it.  I do know it is very close to Lancaster where tourism is a big industry, largely because it is located in the heart of the Pennsylvania Dutch (Amish) community.

The show took place at the Toyota arena located on the York fairgrounds.  It was easy to find, it had ample and clean bathroom facilities and the food was better and more reasonably priced than what I’ve experienced at similar venues.  There are also lots of affordable hotels in the area.  I stayed at a Homewood Suites for $101 and I found out at the show that I could have stayed at a Hampton Inn for $79 (I like Hilton hotels).

I am really looking forward to next year’s show and I’ve already started to think about what I’m going to exhibit.  I hope to see you there.  Continue reading 2010 Cabin Fever Model Engineering Show
