Pewter Casting

Today we went to tech and this is all the steps we had to do the make a good pewter casting neckels. So we have to write my name on the MDF, Secondly you trun your drawing over and roughly mark where it is. There after you put the pencil on the back of your final drawing. Then you place your MDF under your drawing. Carefuly trace your final desgin,pressing on it quite hard. your desgin will have transferred to you MDF. Using the scroll saw to cut out the shape from the MDF.Mark up the outside pieces. Ready for shaping on the sander.shaped an ready for pouring.Putting the three piceses togther and holding frimly. Melting the pewter.Then Mr Gundy was scraping off the oxide layer of the pewter. After Mr Gundy started pouring the pewter in the moulds.Then we have to take the cool pewter casting out of the mould. Then we have to cut off the sprue with a junior hacksaw.Then we have to drill the hole into the cast with the beach top pillar drill. After that we have to clean up the edges of the drilled hole. Using the needle files to get a great finish on the edges.Hold the work in a beach vice for areas that need more filing. Getting a good finish...Grits-180,400,1200,.. got to get that great finsh. Using a 1200 Grit with water. Then we have to wipe off the grit. Then Mr Gundy uses the buffer for a good finish. There after Mr Gundy starts to do the polishing with  Brasso for the final shine then we add a clip to make it as a neckels. I realy enjoy making the neckels with Mr Gundy. I am just up to making the edges smooth.Next week I will be up to sanding the cool pewter casting.
