Revised cases too shortly.
The morning after.
Straight into roughing it out.
Ive made out that the uniflow casting was a success, truth is its got a blow hole in it. From the water cores not being able to out gas. Could be welded but I'll use this first one as a machining test dummy, so I need to make up another mold or two. I've copy cast my wooden core boxes into LM13 aluminium core boxes. Much stronger cores and added another core print so they can gas out without sending the gas through the aluminium.
Water core box and hot to cold end transfer core box, the troublesome ones.
Shown here the water core boxes, wood and now metal, plus a Shell Sand core.
Almost, as I look closer I see a water core has broken away and floated up causing the problems. Only one third as there are three cores, bugger it. So not a gassing issue after all.
Devcon mate.
That said i glued an LC head conversion with Devcon as figured it would stay below 70 easy.
Didn't make practice.
Don't you look at my accountant.
He's the only one I've got.
Jolly old NZ aye, sent my cases to get them heat treated in Auckland. Oven broke down, one week, two weeks.
With a refurbished oven, the transformer on the poll outside their factory blew up. One week ...... finally have them back, not melted thankfully and nice to machine, clearly at T6.
I heard that Heat Treatments was in recievership (or was it McGregor Furnaces??) - who does your treatments in Auckland?
Strokers Galore!
