Myford ML10 Travelling Steady ----Machining the casting

(1/1)

Meldonmech:
Hi Guys

Now for the machining, there is a small area of  shrinkage on  one vertical face, so will make it a feature and  machine a  circular  depression to hide it. One my next casting I will make sure there is a big  head around  the pouring hole to compensate for shrinkage.

Blue Chips:
Looks real good, did you use any particular type of aluminum for the casting or just what was around?

Meldonmech:
Hi Guys
               Thanks for the comments. Blue chip I use scrap aluminium, but have found that to achieve a good machined finish I need to use a mix of soft aluminium eg pots and pans, and die cast items, about 50/50.  The zinc and silicon in the castings greatly improves the machinability. I cast the alloy into small ingots before making my own casting.
