Bruce Macbeth Engine, European Version
« on: October 11, 2017, 02:01:34 PM »
I have found a new exercise, for playing around with Fusion 360.
The design copy process is getting more and more fluid and instead of watching TV in the evening I do some CAD work.

It is really fun to see the process.My only future problem will be, how to get the elves from Chris into the south of Germany ?And If they are here, how keep them for one or two years ?

That animation is looking great - something I have only dabbled with in Fusion so far, need to learn more of it. For my next project, was wondering if its possible to animate/joint chain links going around drums and rollers to move parts? Probably can, but it would take a lot of links...

As for the shop elves, maybe we can work out an exchange program, send a few at a time, have each set bring back some of that great German beer!

Hi Chris, until today I have not seen a Fusion Tutorial, but I have seen one from Inventor.

I am sure it will work in Fusion also.
Beer supply should not be the problem.

The model of this engine, with all the necessary  metric modifications, is nearly finished now.
This Fusion 360 is a great and useful toy, I love it.
But now its time to make swarf again, all the current project are waiting for further action.

Yes Dave, this would be a very nice project, but it will take some time to start it. Gears, valve springs and piston rings  are in the box already, but the time is missing and negotiations about postponed retirement are ongoing.

Hi everybody,
not 2019 yet, but some more and intensive work preparation has started now.
I have learned the minimal usage of the Fusion360 CAM module a bit more and so my first programm are prepared for the CNC milling in the brass plates.
The brass plates are ordered and I am waiting for the delievry.
So some swarf will be shown, hopefully in a couple of days.
Until now I have made only some sample cuttings to confirm the settings with the brass and my available cutters.
To be sure that everything will work on my mini mill, I checked the CNC program already with a tooth stick in the collet and a "paper work piece" on the mill table.
It is confirmed now, that the tool-paths are in the available range of my mill. Also the work holding with its hight is confirmed.
Here the simulation of one side plate machining operation.
Some funny pictures of the mill table with the dummy part and the dummy cutter.
Waiting for the postman now.

Getting close to some real swarf Achim. Hope the postman doesn't keep you waiting too long.

Hi everybody,
we have got nearly 50 cm of fresh and wet snow but also a parcel with some brass plates in it.

That is fast progress Achim, and I thought that this engine was only a CAD project, but we will see it running in the future  :ThumbsUp:

That's off to a good start  :ThumbsUp:  :ThumbsUp:  :wine1:

How do you intend to set the valve clearances, eccentric bushes?

Will you solder (soft/hard) the crankcase?
Best regards

Roger

Hi Roger,
currently no idea about the setting of the valve clearance, that is so far away for me at the moment.


Hard (silver) soldering is the task. I have bought some special solder with 590C to 620C degrees melting point and a small Chinese outdoor camping gas cooker for the preheating.

Still having massive problems with the swarfless machining process as it will be used in Boise, Idaho, but happy with the result.

Kind Regards
