    Propane torch advice needed.

    Is this propane torch suitable for silver soldering a 3" diameter copper boiler? I am concerned about picture 4, it doesn't seem to mix propane with air here. Considering buying it used online. It's an "Airco Propane Torch" Thanks, Eric

    Inline twin 4 stroke

    I built this engine a few years ago. It didn't run right away and I put it away. A week or two ago I got it back out and with the help of some nice folks here I got it running: http://www.youtube.com/watch?v=AEiAqewCuOU Now I will continue the build here. It still needs a water pump, rad/fan...

    damn thing won't run

    I built the twin in my profile pic 2 years ago. At that time I tried to run it and it wouldn't go. There were several issues. No compression being the biggest. I put it away. I finally got it back out and replaced the head gasket, redid the valves, put a bigger flywheel. It now has great...

    I have a 10' x 12' shop in my old house. We moved into a home with an unfinished basement. I claimed half of it for my shop. It's about 24' x 24'. Here it is:

    Has anyone ever tried to make a boiler out of an empty propane cylinder such as this one? Designed for pressure, built in relief valve. Nice size for a small/meduim model steamer. Has it been done?

    DIY 5C collet chuck question

    I would like to build a collet chuck for my 8x12 lathe. It will bolt on the existing face plate/chuck adaptor. 2 questions: 1) I would like to build it to incorperate a big nut on the front to tighten against the collets so no draw bar. This will enable long stock to be machined. Is this an...

    VFD added to HF 8x12 lathe

    Here are a couple pictures of the VFD installation. I can now do about 200 RPM to 2000 without a belt change. If I need torque for heavy cutting at low speeds, I will still need to change the belt position. The belt is set for the old 420 RPM position. Old motor was 3/4 HP, 1750 RPM, new motor...

    Cast Iron and galling bolts

    I am putting a VFD on my 8x12 lathe. This means a 3 phase motor needed to be mounted. After removing the old motor, I marked holes to be drilled and tapped into the cast iron for the new motor mount. I was playing with the position of the new motor to get the belts right, so that involved...

    DC Machines - You have to love em.

    OK, since I am all wound up (pun intended) about my solenoid engine running, I want to build another electric machine. I am thinking a regular DC motor with wound armature and field coils. The plan is an open design so all the whirly parts can be seen. As I mentioned in the solenoid post, I...

    swirlmark finish

    I want to add some bling to my solenoid engine. How do you guys get that sweet swirl finish on ali? I can guess it's a wooden dowel and some grit, but want to ask here to be sure. What I mean is this beauty from Bogstandard: E

    Single cylinder solonoid engine design and build

    I drew this one up last night. I need a diversion from a stubborn twin 4 stroke I am trying to start so here it is: I teach electrical to college students so this one could be used as an object lesson when teaching electromagnetism. The coil is located under the aluminum cyclinder cover...

    Spark plug boots

    Anyone ever make any? How? I am sure they can be bought, but I would like to know if there is a "hardware store" way to make them. E

    accurate length of lathe parts..

    Since we can't measure parts while in the chuck, I was wondering how best make parts to the correct length. The way I do it is make the part, part it off a little long. Chuck the part, clean up the face. Remove from chuck and measure. Make a mental note of how much needs to come off, rechuck...

    Oh Dro!

    I hacked a couple $20.00 calipers to make some DRO's for my 8X14 lathe. The z axis is longer than the 6" caliper so it's on magnets and I can move it around a bit. First photo shows x axis, second shows both. Ugly and a shameful misuse of a precision tool but it makes my life easier and they...
