That's what I used for the camshaft in my Cirrus engine. The cam grinder used is one I built as an accessory for my Clarkson tool grinder.

Nicely executed interesting design. Great result!

Hello Matti. Welcome to the group here. You have shared some beautiful projects already! It will be fun to tell my wife what I heard from Finland today (she was born in Mikkeli). Charlie

Excellent progress on a nice engine - thank you for sharing your journey. PM Research lists both 14 and 16 gauge cloth insulated wire on their website in case that is of any interest.

Congratulations Lars! All your perseverance has paid off and you can enjoy sorting out the details knowing that it will run.

Based on my experience with installing a VFD on a Hartford (another Bridgeport clone), you will still have to change pulleys and range. I didn't change the OEM motor so don't have the torque needed for lower speeds. Even a modern "gold plated" VFD specific motor would not likely cover the full...

Thank you for sharing your journey on this project Andrew. Excellent result. Looking forward to your starter and tank solutions for selfish reasons ... a set of drawings and the small parts set are on a shelf in my shed.

These are the ones I used on my Duclos Odds 'n' Ends engine ... the 30mm x 30mm size. https://www.aliexpress.com/item/32872315657.html?spm=a2g0o.order_list.0.0.152a18026UOPTt Charlie

It may be a micarta moulded rod - a common insulation material from years gone by. I've only used small pieces of it over the years as they came to hand. One piece ended up as the ignition distributor body and cap for my Aeronca E113 model. Here is a link to a site selling what you may have...

That is funny! I guess you haven't been spending enough time in vintage "aeroengine world". They were a very innovative response to "there has to be a better way". https://simanaitissays.com/2021/11/13/b-c-hucks-maarvelous-starter/ Charlie

Another option is to make a "Hucks starter" style of hub that can be driven by a matching dog in a drill/driver. It provides a very solid connection that disengages easily once the engine starts. I've used this approach to good effect on 1/4 scale Cirrus and Anzani engines. Of course, this...

Great result John! The changes you made are a good addition. It's nice to see another engine running on one of your magnetos! Charlie

I believe John Chenery ran his engine with a 20x8 propeller and saw 3000+ rpm. When purchasing a propeller be sure to check hub thickness and diameter. In my experience many are much to thin to use with fabricating spacer(s). That would look odd, in my opinion. Also, be aware that with the...

Vietti - One option would be to try a "Tiny Tach" or similar. They use an induction pickup from the spark plug lead (just a couple turns of small gauge wire). I don't recall if 'Tiny Tach' has a single cylinder option or not ... If this is going to be on a hit 'n' miss engine a digital tach...

Very nice engine! It is one of the more challenging "Elmer" designs and yours looks good. I'm sure it will run nicely too.

Simply beautiful ...

Inspiring result Terry. You certainly do have the painting down pat ... on top of all your other capabilities! Charlie

You are a very patient fellow with results to prove it! A lot of hours but you are achieving your expectations and standards.

Yes indeed - they did turn out well. Glad you are happy with the result (we can be our own worse critics).

That is a wonderful setup Luke. Something to be proud of. You certainly have the "casting bug" and turn out high quality work. Charlie
