Also checkout http://www.buildyouridea.com he uses lost foam casting and also shows how he built his foundry.
Here is a part I just cast using the lost foam method. This is a bracket for the Dewalt laminate trimer I use on my router. This way I can use my winpy machine to make parts in foam that I can then cast in aluminum. The machine evolve on itself and does not require me to buy whole bunch of costly aluminum plates. The finish is of course in the +- 0.02 or so but for critical parts I have to go to the friendly machine shop...
Lost foam must be covered with a kind of high-temp plaster to obtain that finish tough... Hope it help

I know this is the "post your mould" thread but it's raining outside so i'll post the last major thing I cast. It's a turbine impeller housing (i'll post the moulds later as they took a little working out for the parting line)

Here are some of my setup: http://www.nconnect.net/~jgro/foundry.htm

Some more pictures of the furnace and moulding area (a couple of moulds in view including a pattern plate) My furnace is a little different in that it uses gas oil (diesel) I also have a decommisioned gas burner but gas is expensive here UK the flasks and moulding bench are all proprietry products made by Flamefast I bought them as a job lot when a school 70 miles away had to close it's metalworking facility (health and safety.... :sigh: ) they were on ebay so I placed a bid and bought the whole shebang which explains why theres 2 of everything in therethe sand is "Mansbond" oil bonded (Petrobond) it's an amazing sand which if you have a good mould then you have no finishing to do, there is 100kg of this sand in the centre section of the moulding bench. The burner unit is a 950.000btu unit which is one of 2 I bought 15 years ago after I figured that if the local Aluminium foundry could use them then I could too
I have a friend who installs/repairs these so I did a deal and got 2 plus nozzles in 1/2 GPH increments (btw if you're interested in doing some sand casting then go and visit a local founders/casting company...i've visited various places and tbh they are amazed that anyone is interested...oh and make sure you come away with some goodies
) I believe the main reason I started doing this around 20 years ago was just for the hell of it :shrug:

I'm ready to start the mechanical side of my Warco GH mill now. Today I got one Axis done! The picture during shakeout shows the pattern used to make the mould. It's been a busy day herejust needs a coupling and i'll play with that axis and see if I need reduction on the leadsrew.

Just melted my previous casting down and rammed this mould to make the MKII version. Great thing about casting is to be able to change your mind and not lose the materialsNot considered lost foam casting...yet...I have no need for it thus far.

I want to do alloy casting, on a very small scale, but don't really know where to start...
Nice setup you have Kipper.

Outstanding stuff, Kipper! Very nice work, and it looks as if you have a nice, organized space in which you play!

Consistency is a good thing....unless you're consistently an idiot.
