    Scotty's Boll Aero Glow

    Here is my rendition of the Boll Aero Glow .49 cu in. It is a simple and nice engine to build, not too big or too small. I enjoyed the build and finally got the motivation to finish it up and get it running so I could cross it off of my build list.

    Sold KEEPING - Complete and Clean Set of MODEL ENGINE BUILDER - Issues 1 through 27

    I collected this set over time and haven't really looked at them for a while. These are all of the issues that were available in print, everything after is digital only. All issues are in great condition and complete with all drawings, and lots of great articles. I am thinking $175 plus...

    The North Pole

    Rather than derail Ray's awesome Edwards 5 build thread, I figured I'd throw my off-topic comments here. As previously posted: "The earths north pole has a polarity of south that is why the compass needle that has a north polarity is attracted to it. I removed all the magnets and reinstalled...

    What engine is this (HMEM Advertise with us) ?

    I'm sure I've heard the name of this engine at some point, but it is not coming to me.

    Harbor Freight / Rong Fu Improvements (HF #33686 Round Column)

    I recently received an HMEM membership sticker in the mail and stuck it to the side of the pulley cover on my mill and was amazed at what an improvement it made. The thing does not clatter like it used to and it is so quiet and smooth, almost a mirror finish cut instead of looking sometimes...

    Flywheel Castings

    Maybe this has been put out there before, but I just discovered it for myself... If only there was a basic (and super cheap) casting readily available to make nice flywheels with. This will work :)

    DC Motor Conversion on Round Column Mill

    I haven't been very busy with my engine projects but I am finishing up with getting variable speed on my mill thanks to a treadmill or two. All in all, it went pretty smoothly and motor lined up well. I need to stretch the wires from the motor, but I didn't have any nice 12Ga wire on hand...

Nice and clean portable 2 channel oscilloscope, with built in DMM and backlit display, great quality and works great, no battery, but includes power adapter and original Fluke scope probe. The connector for channel 1...

    Thinning out a bit - Is anyone interested in these guys? All have good compression and turn smooth and should run or use them for the cylinders/pistons in another project. How about $15 each shipped USA or make an offer?

    Oh my...

    My son wanted me print some crazy action figure for him and I knew it was a little risky so I debated putting new tape on the bed and setting the Z zero a bit tighter to the table, but no, "it will be fine". This is what was waiting for me this morning: Printing another now, I'll update on the...

    Lynx 15cc Related Questions -

    Can anyone provide me with the part numbers and sources for the pulleys and belt used in the Lynx OHC ? Also, is about the only place to find the Lynx drawings on Pocketmags? I'd like to eventually get these plans. Thanks!

    Upshur Vertical(s)

    I never really had a lot of interest in this engine, but the more I looked at it, the more I liked it and thought it would be a very worthwhile project. Since all of the parts are relatively small and easy to do (so far) I figured why not do a couple of them while I was at it. Then, I started...

    So many plans... / 4-stroke Cox

    As I look through all of the plans, pics and other documents that I have collected and try to sort and prioritize my to do list that I am always adding, sorting, and on a rare occasion, removing items. I do enjoy that process, but I need to stop that for a while and actually get busy on one if...

    Wanted - Issue #20 - Model Engine Builder

    Small Ignition Coil Drive Question

    Has anyone used a coil like this one? It is used on small Honda motorcycle engines and are easy to find on ebay. I would imagine it is tailored for CDI use, and it may not work well with basic points/condenser driving it? It has a 1.2 ohm primary and a 2K ohm secondary. A more standard...

    Scotty's Tiny Inline 4

    I started making some of the parts for this engine a little while back, and since my Webster is now running, I figured I'd keep going on this one and build a base for the project. The base for this and the Webster are basically the same size and they will look nice sitting next to each other...

    Hello from Fargo

    I've been lurking around here for a bit, but I don't think I did an introduction. I pickup up a HF mini lathe >10 years ago and have access to a bridgeport at work and I learned the basics. I just picked up a HF 33686 mill for a price that I had no choice but to buy it. I have been messing...
