This time we went for a 'case study' appraoch and flexed our brain muscles for a bit of a challenge.
After seeing things like this on the web and print brouchures we thought we would give it ago outselves.
Solidworks still being new to us, I went in and drew up a fly wheel which overall was pretty simple - I did draw it three times before we were satisfied however!
Using the mould tools integrated into solidworks - and several hours of trying to figure things out we got our two peice mould, made a quick STL and off we went to the printer.
So when all the prints were out - cleaned off with the air but we were impatant and took it out before they had finnished being baked in the machine - so we transfered them into the oven upstairs for a blast for around 30 mins.
Being a bit of a noob the pour hole was a little small - so I countersunked it to enlarge - and maskeing taped the two halves together. We then embeded it into the sand pit ready for a pour.
And the pour..
After a short period to let the pewter cool - we got the part out the sand and peeled off the tape.
We were suprised of the weight - assuming things must have gone what right for us!
Hitting it with a hammer - the only solution for a stuborn mould!
After a demoulding by hammers - scrapers and a quick sandblast we have the part!!
And the money shot:
