The reason is that gases are dissolved or trapped in the molten metal. When such cast parts are heated up to higher temperatures which are necessary for heat treatment operations, these gases expand and form bubbles with a negative impact on the mechanical strength and the dimensional accuracy of the parts. A way out is offered by procedures such as vacuum diecasting [1] and laminar die-casting. Precipitation Hardening Parts which are made of heat-treatable alloys and produced with the mentioned procedures can be heat-treated. It is characteristic for the vacuum die-casting procedure that all areas of a casting machine which are reached by the melt are evacuated.

Report comment Reply Nevermind me in the later videos the risers are kathe. If you have never used a metal cutting lathe and plan to build a Gingery based lathe it will be a great learning experience, and you will never know the difference from a REAL lathe of the same size and the Gingery lathe. Gingery Lathe Re-hashed Nice feedback like this really makes me want to complete the shaper, mill, and other projects too. To me, this was one of the great learning experiences of a lifetime. The disadvantage is higher friction and a lower lifespan, but for the first—just get a slightly bigger motor. The Best Gingery Lathe Video Series To Date Sign up for the Make: Quite curious how gingeey detail with the lathe cuck will be solved and if the rod, which is holding the chuck is going to be hollow.
