I put my own ignition system together for my twin cylinder mini hog. It has worked very well.

Well I am set up I could wip out more side plates and the lower landing rudders. I am in the process of making a form die to bend them. How many are we talking about?

Chriske Already found the smallest OD-16mm pyrex tubes. I have more then I need. So I can send you a set. Problem is I can't find the second box containing the larger tubes :mad: but I'll keep looking... Did you go with different size tube the drawings I have call out 22mm for the large and...

I use a cup wheel set on center tilted for the primary and secondary relief angles. I haven't videoed sharpening the ends something I probably should do. Anyway I have done a couple on sharpening the flutes though.

Chriske I have a question I've been lining up material and am about to start a build but havent been able to locate a supplier for the proper sized glass test tube. Can you tell me where you found them. Right now I'm thinking of using a different size than whats shown in the plan.

Yep you are correct I did this with a cheap coil that I had a few just to see. It lasted a lot longer than I expected matter fact I ran an engine with this coil for several years before it pooped out on me. Worse is not giving the coil a place to discharge the secondary windings will eventually...

The coil used was a Ford 12v coil pack.

I was looking back at some of my old videos and here is one that I am using a 6v battery on a auto coil pack and the spark I get out of it. lol

Motors have pretty decent compression never checked any or know what they are I run a .020 plug gap on a home made plug and also have run the same on I think a cm-6.

I use a coil pack from an auto and run on 6v with no problem. I use a resistor to bring the resistance to around 2 ohms and run with a hall with ignition boards that I made. You can also use a tm6 board as long as you use a ballist to bring the resistance to around 2ohms. I've ran it on current...

Not sure they are the same but I used coil packs before I started winding my own coils to reduce the size down to the size of a letter D battery. Here are the ones I used with very good luck at 6v but they are 12v...

Put together a voltage divider. you only need 1k,1.5k and a 4k resistor to divide the voltage to 6.25v

They are offered on this site. http://zeamon.com/wordpress/?p=733

This is the tool post quick change I made and use on my lathe. I originally designed it in pencil back around 2004 I later put it into cad around 2008. I have made a few of these and given them to friends of mine. Not extremely hard to make and prforms very well.

Here is the drawing for a tool post quick change I designed up and made for my lathe a long time ago. I did a build thread way back but seems to have gone missing. But here is the drawing and a 3d pdf file also.

LOL that maybe my winters engine project. I have started to model it up in cad last spring and worked on it a little here and there this summer. I usually pick an engine to build over winter and do a video log of it. I have 2 engines right now that I'm thinking of and like I said this is one of...

I purchased a Bridgeport quick change for my N/C miill. Been wanting a quick change for it for some time now (like since I got the mill lol). Am very happy with the run out of the holders. Will be a nice addition to my N/C Now I need to make a tool setting station for it. Here is a video of the...

Mostly used for scribeing.

Just turn up some plugs they don't need to be pressed on. They are there to keep wrist pin in place and keep wrist pin from making contact with cylinder wall. Usingwrist pin plugs is so you don't need any other means of keeping them in place. Just put a small plug on both sides and no need to...

The setup I built does the ends of endmills plus the sides doing primary and secondary relief angles. I am very happy with it and have sharpened a lot of endmills with it. It really didn't cost a lot to build. If I were guess it was under $150 since I had the metal and the only cost was the...
