I was talking with the foundry today. The Induction Manifold has been cast, I have just paid for it and it should now be in the first class post on it's way to me. I had to pay the cost for a complete investment flask as my casting was too large to share the flask space with other customers. So if you see me limping, you will understand it cost an arm and a leg.

While I was waiting, I decided to make some chips...... lots of chips.
I started with a couple of 2 inch by 2 inch by 2 inch blocks of 6084 aluminium with the intention of making a pair of Magneto front housings.  The Jupiter was fitted with a pair of BTH SC9 nine cylinder magnetos mounted on the rear face of the engines crankcase. The first opp was to machine the mounting flange, the bearing housing and to drill and tap all the mounting holes; all at the same setting, so everything should be nice and concentric.



The embryo magnet housings were attached to a fixture plate, held in the machine vice, so that the main part of the two housings could be machined. As you can see most of the two aluminium blocks disappeared into a mountain of chips. Fortunately, there was a magneto housings hidden inside each block.



This is as far as I have got. The magneto housings are nearly finished but I have discovered the rear cover for the crankcase cover will need to have some additional material removed from both magneto mounting flanges before everything will fit together. There's always something that does not quite fit.







Stay tuned

Mike

Mike,
The Magneto housings look great. I look forward to seeing the manifold.

Thanks guys for looking in and saying hello.

Thanks also to Jo for accidentally deleting this post first time around.   :killcomputer:

The postman, bearing wondrous gifts, knocked on the door early this morning. For once, I did not mind getting up to sign for the package for it contained the final casting from 'Just Castings',  the Induction Manifold for the Jupiter engine. They had done another excellent job with this casting, as I have come to expect from them. It needed only a few strokes with a fine file to clean up the flange faces ready for a final skim cut on the mill. I still need to clean up the inflow risers and a few other blemishes, but really there is very little work required.


This is an image of the full size item taken from the works manual.











As you can see, it's quite a large casting and consists of three separate passages from the three barrel carburetter to the rear of the engine. The typical wall thickness is between 1.5 and 2.0 mm. 'Just Casting' inform me it consumed 123.5 grams (about 5 ounces) of aluminium, being jewelers, they always charge for the metal by the gram. I am pleased I did not ask for silver or gold.

It has been a long interesting journey into areas unknow and I am very pleased with the result.

Happy, happy, happy

Mike

Hi Jo,

Not a problem, but don't make a habit of it. :lolb:

As for the cost, it's only the kid's inheritance after all, and I got to spend it before them. :LittleDevil:

You know, they did not include any candies this time, may not use them again.

Cheers

Mike

Phone them up and tell them that your grandson was very disappointed with not getting his sweeties this time - I am sure that a company like that with a reputation to maintain will oblige  ::)

I hate to think what each sweet cost you  :facepalm2:

This project continues to amaze me.  I may have to make a trip to the UK just to see it when you get it done !

On a side note, every wonder what these jewelry makers are thinking about the work you're asking them to do?

This project is certainly in that class of "I'll never get there but 'boy' wouldn't it be nice?".

In any case... I'm learning things and that's invaluable.
