My webster build

<< < (3/7) > >>

NickG:
Very nice example. Strangely I was asking questions about these little ignition modules in another post. The thinking was that it could be used on a model scale but now we have 1st hand proof. Like the novel method of altering the ignition timing too.  :thumbup: Some of the really old cars used to have an advance / retard lever on the dashboard. Probably as they didn't have things like vacuum advance in those days. I love the fact that like Bogs' minimag it's a self contained unit. Otherwise you need a battery and a circuit or worse still, a battery, points, coil, condensor etc! It's also good to see yet another example of Jan Ridders vapour carb working reliably.

Well done.

Chris, still watching yours avidly - I reckon you've done the hardest bit - just keep being methodical and plugging away - you've made gears before that would have worked so I'm not worried about that in the slightest. Everybody works at their own pace, you saw when I started my two 'poppin' engines - a year later and I still only have 1 and a box of bits!  :doh:

I`m building one of these, my build log is on the forum, and I must have spent more time just building and attempting a gear (still not done it!) than you have on the entire engine. I`m selling up.

Chris,  Don't ever give up!  I was just about to make a big gear hobbing and indexing mount for my mini lathe cross slide with x and y adjusting and a cutter to put in the three jaw, etc, etc, etc, when I decided that a little hand work was easier than days making tooling.  The aluminum gears mesh well and have worn into each other perfectly.  I had to adjust where the "stock" webster mounting holes were into the crank support because I was not using the purchased gears, but the backlash is about perfect and the gears make little noise when runing.  

I will put some pics together tonight demonstrating what I did to cut the gears.  If you have a dremel and a small cutting disk, it is just shaping one tooth at a time.  even if you do not have a gear to model after, you can bisect the blank 10 times and you have 20 teeth, 20 times you have 40 teeth.  There is nothing magical about the 20 or 40, just that it is a 2:1 ratio.  you can use the dimensions in the plans for your blanks.

Doug,

Great work and wonderful engine - I doubt anything can exceed the thrill of that first design actually coming to life, and this certainly qualifies as your design.

Looking forward to seeing more details, especially on the ignition system.

Best,
Mike

HOLY CRAP!!!...great job... :bow: :jaw:

Doug, I`d really like to see more pics of the gears if you could! Nick, thanks for the comment, I`ll keep plodding on....
