Here we go! Finished, tested and running! Here is the class of 2012!

Thanks guys and John we all pondered the value last night when we locked up! These will be gifts to the Presidents, Dean's and adviser's of each of our state's Universities next week. The materials and tooling were all donated by B&G Machine out of Philadelphia which really helped us a ton. I...

The story continues with progress on our 40 engine build! The students have programmed all of the components in G Code (manually) and made fixtures, soft jaws and all of the proceedures. They have been running the parts in our Haas cnc machines over the past two weeks as a production run. Here...

Thanks Gerald. We are setting up to do a production run of 40 "engines" and I will post that too. I will get our prints together and post them to HMEM's plans too.

Thanks Ralph and John! I like projects that become something if not useful then interesting. John, I agree nothing about this couldn't be done manually but for a CNC curriculum I am proud to say we spend a full year in manual machining before going in to CNC and I require 30 hours of manual...

Much progress has been made and many engines are finishing up nicely! This is one of several completed today. This has been a fun and challenging project that incorporated many machining processes. Thanks to Bogs for hints on the layout too, I know I need to make the lever a bit longer as the...

The students have been making a lot of progress and you may realize that as a CNC project we will do things a little different than you might at home but I encourage thinking for themselves and even allow treading down the wrong path in the name of "teachable moments" as they say in education...

Master cam has an excellent import function but is of course a full blown cad/ cam , expensive and very cool to engrave with. But if it is a business decision and what you want to do I really like it. I would love to hear more of any users experience with a lower cost alternatives.

We are well on our way (my cnc class) to making 15 treadle engines. Students are programming all of these parts with G Code, no cheatin with Gibbscam or MasterCAM yet! Here is a base and column finished today. I assigned 70 pages of reading and was informed it is SuperBowl weekend. I didn't...

Hi Kelly , congratulations. If your haas lathe has the intuitive programming on it keep in mind that is a powerful way to build programs and keep in mind you can add a facing routine to a roughing and finish all in the control. I like to teach the use of the intuitive and constructing that way...

That is awesome! Really fun.

Maybe he hopes the footpeg will become the industry standard. It is not plain, S.S., investment cast etc. What is Bog?

John, This video is perfect to share! Thanks. The dimensions I had were off from your suggestions and I've adjusted it accordingly. I have a question though. Last week I designed a trials motorcycle footpeg for a company in England and the customer said in one e mail "make it bogstandard!" . I...

I took the suggestions in to consideration and came up with some changes. If we get through this we can consider the double treadle. Take a look. and..

Well Gail, that is a really good point, back to the drawing board and John, double back to the drawing board! I really appreciate the input! I don't want a student project that doesn't work. And yes this is way more fun than the classic punch and brass hammer projects!

Treadle Finger Engine I've drawn this model up in solidworks as a CNC project for the students in our CNC course at the University of Montana Helena College of Technology. Our goal is to manually program most of the parts using G-code. I've based the design off many I found on HMEM and links...

I tell my students, to heck with this modeling business I'm going to just make a giant penny and occasionally post pictures of it next to various engines and machines"

This is amazing. I can't wait to see what you do with this! Best wishes! Tom

Our brave little Jack would do the same thing! Wonderful story"
