Welcome to do with casting I do not know the first time I tried casting 3 months ago purely out of curiosity and interest in this. If someone wants to repeat, I will describe what is needed:
1) Raw materials for casting, I for this purpose ruthlessly destroyed the hammer block engine ZMZ-402 it is made of cast alloy AK4. Also use a variety of motor scrap: pistons, pumps, manifolds and other parts of the engine. For melting is not necessary to unscrew the bolts and studs, they remain at the bottom of the melting crucible only need to periodically shake them.
2) furnace for melting
3) Crucible (any seamless pipe brewed with bottom)
4) Charcoal (normal, which buy for barbecue)
5) Flasks (wooden frame for form)
6) The sieved sand and silicate glue (“water glass”)
1) to prepare a mixture of liquid glass with sand. I kneaded the bucket building mixer.
2) Removed from the mold blank (it should be more future disk due allowance for turning). Note the relative position of the framework, I used furniture pins.
3) Wait until everything is dry (the longer the better) for about 3 days.
4) threw a fire broke out when a well, put pot, add coals and turn on the blower.
5) The molten aluminum poured into molds. When the metal froze slugger crust, sprues and risers.
7) Assemble the disc. For these purposes, bought 10 M8 screws with hexagon socket and 10 nuts M8 with nylon ring.
Raw materials for the future drives (block ZMZ-402)
The largest pieces are able to fight off a sledgehammer – for remelting
Furnace for melting (from disk GAZ 53) and the crucible
All that remains of the remelting scrap motor
The excess will be used for the following activities
Flask, sand and silicate glue
Form №1 allowed to dry and ready to fill
Aluminum filled, the form cools
Immediately after pouring
Get 2 half-disks
As a result, got the same blank 4
Next disc to be processed on a lathe
The final result
