Cincinnati Shaper

Ha.. I think my heart trouble came from the same source!!

Dave give me a day or two, I'll see what I have around here. The rods would depend on how much Chrome they have, Chrome isn't good for machining. I never noticed if they have alloys listed on tig rods. I'm still reading, too much info out there.

been digging in my copy of cast metals and from the looks of things about the only thing I can do besides cooling rate's is add copper, the rest of the alloying metals is basically going to be out of my reach except for probably small amounts of nickel if I can find a source.

I got all the time in the world, what with no job and only the shop monster and me to worry about. There is some arc welding rods that have a high nickel content, but most places you have to take out a second mortgage on your house to buy so I'm not too sure that will be a viable option.

I made some pumkin pie's yesterday


a buddy dropped by this morning for coffee, him and the monster had pie I didn't get any they then decided it was nap time.



lesson learned is don't let either one of them know you made pie.

Shop monster looks comfy , what's the piece of machinery in the background

damn pie theives.

9 X 18 inch lathe. I'm thinking it may be my next project, it needs to be made into somehting that will actually make precision parts instead of what it does now. first off for it will be a couple new belt drive sheave's.

anyway I been thinking about a new handle for the ram on the shaper, here's what I'm thinking about, maybe do it in bronze to match the handcrank.

Hey Dallen, I have spent most of the day catching up on the shaper build. You are one tough and persistent guy!

In looking at the pictures of your iron I am reminded of some problems I had. The iron I was melting was a strange alloy. It was from engine cylinder liners. It would melt, turn dark and became very thick. The resulting castings had a black scale on them similar to what I saw on some of your castings. On your next melt use all virgin scrap with one or two "re-recycles" of your previously melted iron (90/10 split). When you break the scrap it should have an even grey look to it. Anything shiny, polished or chromed should not be used. Try just the copper and silicon just before you pour and you should have great results.

I'm not really as tough and persistent as your trying to make me out to be, I just don't have anything else to do except mow the grass, do the laundry, and chase the dog around the yard.

I'm going to try some copper next time I melt some Iron, plus I've located a source for some Nickel in some welding rods a buddy of mine has he said I could have a couple to try.

the iron that I have is good iron from bearing housing and gear boxes, I wouldn't try to melt cylinder liners on a bet, or brake rotors rotors are some nasty crap what with all the rust thats up in them.

I don't know exactly when I will attempt to pour Iron again but hopefully in a day or two if it warms up some.

And I changed my mine on the handle design as I had to redraw it for the cnc router guy gotta keep him happy.
I think this is much more pleasing to the eye.

well its almost that time and I just want to wish everyone a happy turkey day, and for the guy's that don't celebrate it have a nice day also.

Damn Shop Monster said he wanted cookies and wasn't going to settle for store bought ones so we broke out the kitchen tools and this is the results, SM said I should of used the furnace to cook em in, and the muller to mix dough with. I told him it would take to much to clean the muller out so we used the kitchen mixer.



guess who got the beater

did some serious cooking today, still having some problems with the burner seeming to plug up from crap in the fuel, going for a strainer tomorrow.
Added about 3 oz of copper and 1 oz of silicon to the melt which was in and A10 about half full, throwed in a nicast welding rod but it didn't melt so next time it gets put in the bottom of the pot first off.
Tried one of the chunks from the ingot tray with a file it cut nice so stuck it in the mill and took a couple of passes it had some hard edges but they were really thin.

Here's the photos of the part

[dallen]

did some work on the part in the above post, found what looks to be a slag inclusion hiding in the part of the ring where the gate was at, was able to cut the part out with a hacksaw for a photographic session here's the results

Is that slag or sand or what, it looks a little strange?
I don't know what to think about the Nickel not melting, may need to have a nickel/Iron alloy.
