You can use micro ballons ( white powder ) to make your Rencast go a little further. I somtimes pack wood in the cavity to be poured to take up space ( less Rencast used ). You may end up with out of date Rencast, no problem, it just goes off faster as it gets older. I do all the micro and part A mixing first, then when mixed in good add the part B, mix quick and pour.
I have been ringing up and visiting various refactory companies trying to find out who is interested in helping the "little foundryman" hard work but good advice and help from some.
The patternmaking part will be enjoyable but still a challenge as it will combine just about every skill I can muster!
Neill probably already knows all the pitfalls which I will be stepping blindly into, but then he climbed out ok, so here's hoping.
Cheers,
Will.
Looks like I'm in the same boat, the foundry I use is closing down ( China has taken all the work ) seems I will have to restart my experimental home foundry again, bugger!
What a shame for all the skilled workers in a niche market.
Don't you look at my accountant.
He's the only one I've got.
You might be able to buy some cheap gear.
Not funny in the circumstances I guess!
What next? could it possibly be, that after designing a revolutionary engine, we will send the plans to China and in a few weeks a brand new motor all sorted out and for the cost of the material, will arrive on the doorstep (followed by a few thousand clones destined for the shop shelves!).
Like hell!
Kiwi Ingenuity needs to re-ignited! - Present company (Bucket racers) accepted.
Will.
Don't get me started on China!
Yes there will probably be some cheap gear going but it's all big stuff. Poor bugger.
The thing is soon there will be no one left able to do decent castings, know the old tricks, yes Greg is certainly a skilled opperator. This is a very unfortunate situation ( I'm thinking selfishly also ).
Two left in the SI as far as i know...Rangiora and Nelson.
Used to be four in the ChCh area alone....
Wire makers used to be a bit up and down. Yeah it's a bit short sighted, if you look at history man is so often at war. In modern times, he who can out manufacture his oponent wins. Oh there'll never be another war. But why do you think the US was trying so hard to bolster the car industry? Well think.
Don't you look at my accountant.
He's the only one I've got.
Maybe because it keeps the angry young men employed and busy, otherwise they would have to put them in the army, then they would have to go and find another war either to get rid of them or at least to keep this huge army occupied trying to prevent other rising powers from grabbing middle east oil!
Reckon it would be cheaper to put the money into bike tracks to get rid of all that surplus energy and aggression!
But now, I want to do my bit to keep the foundry channel working, - has the fire finally gone out?
Will.
No, just busy doing other stuff. I've been trying to get my Autogyro engine going again ( starter failed ) so I've been organising a different system ( starter gearbox ). The first unit I built was a bit flimsy so I got what I deserved. I'm using the new found usefulness of the gear hobb to make the starter gear drive with reverse load slipping clutch for gear tooth safety.
Getting off track a little here, sorry, but I was checking out foundry ceramics - that sort of stuff and I came across this - we were talking about skilled people earlier, you've just got to see this!!

All sped up here and there of course, but they are unbelievably good bricklayers, (like foundrymen)
They are Speaking Spanish I think so they may be from Central America / Mexico and I don't think anyone knows much more about brickwork than them!
By the way Neill, is that David Brown Gearcutter I saw in the background of your workshop a hobbing machine, or a gear shaper?
Will
It's a hobb, maybe a gear shaper next.
This is the Armstrong drawings and so forth they were for sale recently.
