Well you old piroque paddler you ;). Don the parts look darn good :ThumbsUp: :ThumbsUp:. I'm starting to think you and Crueby have a huge stash of brass hiding somewhere   :thinking:.  I have my  :popcorn: and  :DrinkPint: and I am watching you bud.

Well, I know I have a stockpile built up - while buying for the Shay I've been buying extra as sales come along for the next project or six.

Don - flywheel looks great - gotta bookmark this one for future reference!

Watching along too....  :popcorn:  :DrinkPint:

Hi Don, Haven't been around much this last week so only just seen this new thread of yours and, after a search through the threads as well, finally found your post on the bevel gears. Early stages Don but, lovely work as usual  - more 'Micro Magic' indeed  :ThumbsUp: - and what a companion it will make for the Benson. What with my mate Chris doing them in half scale, your 'brass and steel' beauties and the tad larger versions from Jason and myself  there's no lack of individualism on AM's designs that's for sure.

Looking forward to the coming progress

Regards - Ramon

Don-

I just tuned in.  The spokes are beautiful.  If that is a precursor to what's coming,  it will be stunning.

 No, I haven't given up.  Two of my kids swim competitively and now is their main season.  Between practice and meets, it's very hard to get shop time.  The little that I do get has been on side projects that take forever.

Great start Don  :ThumbsUp:

Sounds like everyone's shop time is limited...  Haven't even been into mine for more than a month  :disappointed:

Kind regards, Arnold
Building an engine takes Patience, Planning, Preparation and Machining.
Procrastination is nearly the same, but it precludes machining.
Thus, an engine will only be built once the procrastination stops and the machining begins!

I had some free time today so I thought I would start with the base. This fabrication started with a piece of .5"x.75" bar stock and a .125 x 3" flat plate. I mitered the ends of the bar stock close to length and finish to diameter on the belt sander. After fitting them together for a test fit I cut a slot into them to fit the flat plate into. The flat plate was then milled the fit the opening.

The first photo I am showing cutting the miter joints.

This second photo is test fitting the pieces to see if all is square.

Trimming the edges on the bracket to fit the plate.


Finishing up with the flat plate squaring of the edges.

A look at the two piece together.

The base assembled together and ready for silver brazing.


Tomorrow if time permits I will clean the pieces and silver braze the base together.
Thanks for looking.

Don

Looks great Don and that brass should solder together well, but with that much heat sink its going to take some serious heat too  ;)

Thanks Bill, my torch has an oxygen bottle so no sweat. Got all the brazing done and managed to finish the milling on the base. The silver soldering went well not a good as I would of liked but the results were great.
After the brazing I move to the mill to start fly cutting the top and sorry guys no photos as I can,t do both at the same time.

Next after I established my datum we start to cut the holes.

I had to make a cutter to be able to trim the edges so this is it.


Now with the tool made I started trimming the edges. I am cutting .125 into the edges.

Now I wouldn't be nice if I didn't show you the base after all that work. Keep in mind I still have plenty of sanding and cleaning to do before it's like I want. I do have one mishap and if you look at the rectangle you can see where the cutter was move to far. I will have to see if it's covered, if not I will try to add some silver solder to it.





Thanks for looking and Monday I start a job out of town should be back in a couple of days.

Very nice Don. Happy the soldering went well too!  The angle on the sides definitely gives it that "casting" appearance.
