lately I've tried a little way on how to best zamak (zinc alloy is a hard) to parts, preferably, pour into chains and where the limits are for it.
Zamak is indeed not a very easy flowing alloy and therefore has limits to this process on metal konvetionelle kind. I have since made some attempts to make an early T34 chain and it is at least possible.
However, the Committee is too high and unacceptable. So I will now once the next 2-3 days I again invest to build a machine.
After I have collected most of the parts now, I started today to turn a spindle in me first. But I have to cut me off a piece of cutting steel with 70mm diameter.
I turn to about 15mm from 16mm diameter up first. A lot of chips ....
I can then make the fits for two thick stock to me.
Once the spindle is rotated so far I still need the storage side. I'm from a 80mm aluminum piece I turn high and 30mm from both sides who affixes the bearing seats.
For the transmission of power I use a 8mm round belts and turn me well for two pulleys, so that I determine that the extractor is later controlled from 50 to 1800 rpm.
The drive I'm using an old sewing machine motor, I control with a dimmer.
Once I have the bearing side is also provided with an approach sees the drive spindle now like this.
In the meantime my portal mill works and has already cut out a container ring and the base plate of 10mm aluminum.
