I have a final problem. As the image shows (down at images), the surface on my piece is filled with small black inclusions. The vents that filled during the pour don't have the problem. That's a problem I want.

I have a Lincoln Power MIG 140C (Continuously Adjustable) setup for sale… The welder, accessories with a large new gas bottle all on a 4-wheel cart. I bought the system new about three years ago for a series of projects that didn’t come to fruition and now it just sits. There’s about eight hours of use on it. It’s very clean, all documents, practically new. I will sell the entire setup for $500.00, local pick up or reasonable meetup… Central Connecticut. Ross @ 860-267-0279

hi guys i have to texture a piece of 8mm steel about 5 ft long and a funny shape! i was thinking i would clamp it to my heavy bench and heat it with the gas torch and texture sections like that, in the hope that i do not deform the plate too much.

Time and the elements have finally caught up with my truck, it seems. I bought it slightly used about nine years ago because I wanted the utility body for carrying tools. The stock rack was handy for carrying 20' lengths of steel, too. Unfortunately, the cabinets in the utility body are just too shallow to hold a number of my tool boxes, so they wound up being carried in the cab anyway. The utility body also costs me pretty heavily on gas mileage. Still, it was paid for so I used it.

I ran across a pop-up ad on the web for this Multiplaz welder: (https://www.facebook.com/MultiplazUSA#!/MultiplazUSA ) and wonder if anyone has used or heard about it. I did a search on the Artmetal.com site thinking there might be a thread, but did not come across one.
ed dravo - Tuesday, April 30, 2013 - 4:36pmCasting core | hollow casting
My castings are too heavy and I want to cast a hollow core. My concern is with the material to fill the core. Because the castings have offset cavities it's impossible to drill, scrape the core material out. Something that would dissolve sounds like the best idea. The R&R slurry material will not dissolve, at least not yet after 12 hours under water. I'm thinking plaster/silica. Heated to 1400 F will the plaster disassociate so much it can't work as a bronze barrier? Any ideas?

There have been questions here recently about soldering stainless. Plain steel is difficult to solder; stainless is worse. The difficulty lies in getting the metal tinned. What I do is to tin the metal first on both mating surfaces. Then I can join them easily later. Here is my method. It's 100% effective.

Check out this news story on scissor-making in China. In the video clip, the smith puts the steel into an old brick forge and heats it - in an induction coil!
