Looking plausible so far and worth pursuing a little further methink.
Sand casting unobtainium parts at home.

No die grinder but a small Dremel was used to seat the bullet shaped object, a coupla allen screws and polishing round 2. Tomoz I will make a securing rim for the lens. On a roll here.
I reckon I will get all those marks out and won't need chrome plating.

Thanks Brother but I'm not there yet.

Alrighty, I have deduced that the small marks are indeed gas holes which I can remedy next time by degassing with Bi-carb in the molten metal, but I am thrilled with the first attempt at home sand casting. Stay tuned for something more ambitious next time.
Is the bullet shaped object a specific car part, or is the final product ornamental?
59 Floride, am I warm?
Bang on Arto it's a light
Ando, may I call you Ando? Of course it is ornamental because it doesn't have a bulb holder. That could change in time but ATM it's ornamental and my first attempt at sand casting.
I can never get aluminium to polish like that. What are the tricks?
Grasshopper Rob, I just use a 9"calico wheel from Bunnings and some green rouge also from Bunnings.
I wonder if I may be audacious enough to attempt a sand cast version of this with a hollow centre (to reduce weight) and a mirror finish. Time will tell I suppose..

Last week I had my smelting furnace running at full revs i.e. gas full-on and compressed air full-on and achieved a temperature of 1047C in the firebox so there are about 953 reasons why I won't be doing any cast steel engine blocks any time soon. :disappr:
Well done on the upgrade, testing...
This would have to work woodnit...?
Not going by those drawings

If you were to make it out of unobtanium it would probably not need a hollow centre as the weight would be minimal and the product certainly corrosion resistant. You would also only have to find another 621 degrees C to melt the unobtanium........
