Part for the Cinci

[dallen]

as most know I been working on and OLD Cincinnati Back Geared Shaper only problem is that it has some parts that are either broken or missing.

one of the missing parts is the ratchet pawl for the table feed, which I started making a pattern a couple weeks ago. well I sorta finished the pattern last night. anyway got enough paint on it that I could ram it up without the sand sticking to it so this morning I melted some metal.

an as they say it didn't happen if theres no picture so here they are.
first up is the setup that I use in one of my furnaces when I have to melt semi large amounts of aluminum.


second is the mold rammed and ready to pour, sorry didn't take any shots of the mold open.


third is of the important stuff, like you can't have a casting without some molten metal to pour into the mold right.


molds all filled up and none left over for the ingot tray


the end results of the mornings playing in the backyard. After casting the pin in the part I remembered that I hadn't coated it in soot plus it had a rough finish which wouldn't let it slip out when I put it in my press.


on the mill and working on the two bores that I need to do.


part on the shaper still have a couple of drilling jobs to do to finish the part


and the required photo that shows the ugly spots in the casting, if this part was for someone else I would of re poured it, the spots you see are from sand that pulled off the edge and ended up in the cavity when the mold was closed.
If this works out I plan to redo this part in cast iron.
