Default First sand casting

Today I poured my very first sandcasting .

Been casting alum for a couple of years now , mostly I simply fill all kinds of tin cans to cast rounds and squares wich can then be used on the lathe and mill .

So I decided to take it one step further , make a pattern and give it a go .
Turned out quite acceptable for a first try .
The part is half a carriage for a moving gantry cnc router I'm building .
The other half was also cast , but I don't have pictures .


Furnace , greensand , flasks and offcourse the pattern ..... it's all homemade .
Greensand was made from construction white sand , powdered bentonite and water . The bentonite was like flower , very fine and dry . I found it at a garden center .

The surplus of molten metal was poured in a couple of tincans .
I use a lot of these round "stock" for all kinds of things .

Couple of more pictures of what it should look like when finished .

The two bores will get 4 lineair bearings wich will slide on two supported rails on a fully supported frame . More a design exercise then a practical machine .

These two "prototypes" were carved out out of a large block I cast in a square paintcan .
Took a lot of metal to remove , the entire shop was full of chips .
And when I finally got there , I goofed up with the two bores .
On both parts .

So start over again from scratch , hence the sand casting to avoid removing all that metal again .
Now let's see if I can getthose bores right this time .

The steppers are rotating nut types .
A fixed leadscrew has several advantages , and the steppers already have an integrated inti backlash nut .
Well worth giving it a try

I'm envious. I hope set up an aluminum foundry some day, perhaps this year or next.

Thx for all the nice comments guys , I'll post some pictures of the furnace I made from a propane tank .

I don't have anyone round here to teach me or to guide me .
So all I've learned sofar comes from the interenet .

There's a guy called myfordboy on youtube showing 50+ video's on patternmaking , moulding , casting .... Very informative , I highly recomend looking at his channel if you want to learn how to do this .

Mrpete222 also has some real nice step by step video's on the subject

And offcourse there are several others .
