Title: Myford ML10 Travelling Steady ----Machining the casting
Post by: Meldonmech on October 18, 2012, 03:33:45 AM

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.

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

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.
