It's been quite a while since I fired up the furnace . This weekend I finally had the time
to melt som ali , make a few moulds etc .
Here's the first . This beautifull flywheel was designed by ken brunskill . He mailed it to me , and I just scaled it a little
and put on some pattern draft .
3D printers are the perfect tool to make patterns . No matter how complex the shape is , as long as "rules" for a pattern are
observed it'll turn out ok .
Just imagine how much work it would have taken to make a wooden pattern .
The pattern printed in pla , no surface treatment was done apart from dusting it with parting powder .
The casting , actually this is the second casting , I did two of them .
The second casting turned out better then the first one . The feeder is in the middle , and four risers on each "corner "
This one has almost no pitting , but still quite some flashing at the parting line .
I guess I'm still a bit clumsy when pulling the pattern from the sand . Or my homemade sand isn't the best quality .
Flywheel will be used on an atkinson differential engine .... someday
Couldn't resist . I cleaned up and machined the first casting . Turned out quite OK altough there is some pitting and a few little blow holes .
I'll make a poly v-belt pulley out of this one to power a gear pump I'm building .
