Here are a couple of parts fresh off the mill, the flywheel frame base's, they were milled up from 10mm SS plate.
I still have some holes to drill and tap in them.

I had to go back through the thread.
Great stuff.
I can't get over the spokes.
Also the polish.
What material is the base? Can you describe a little your polishing methods?

Thanks.

 

[RobWilson]

Many thanks Bob,Tony and ZEE

Zee the base is cast aluminum bronze , i will do my best to describe my polishing method

here is a quick demo just dun it for you zee hope it helps

fist thing to hand saw off piece of brass OOPS MENT FIRST THING TO HAND SAWN OFF PIECE OF BRASS :-[

first step 6" fully stitched mop with satine 120 grit cut very quick removes rough marks and skin

gives a brushed finish

next a 6" fully stitched mop with i cant read the ladle now but its an intermediate polish for brass

this takes out the next smaller marks

Then a 6" loose mop with well i use jewlers rouge

this really brings up the finish to mirror

this demo took about 5 minutes to polish alot less than to wight up

hope it helps

Wow! Thanks Rob. That's great!
So different mops for different grits.
It looks like you take these 'thingies' and apply to the mop...then mop against the part.
What are the 'thingies'? They look like sticks of paste?

Thanks. Really.

Hi Rob

WOW That is really stunning,

I had commented on someone else post saying it looked amazing because it was all done in one metal (brass) and it was/is great looking

and now I see your creation and now I like the mix on this one the silver and gold colours just look right together here, together with the workmanship this engine tho not yet complete is a jaw dropper

keep it up m8 and keep posting as you update
