I have about a 6 month lead time right now
Not been in a good mood, girls will do this to a man... And frustration about terminology being used, there is a clear misunderstanding about...
That is wrong, bring the metal in low and raise into the casting, Best practice is drag runner, cope ingate, run casting in the cope. Not always...
I think maybe you misread that, it would be drag runner, cope ingate. Ref: CMI, Cast Metal Institute
I'll give it a try, be a lot cheaper than replacing old blocks
I have often thought of reusing old crucibles for base blocks....let me know if you figure out how to cut silica carbide
Thats is true...I am talking large molds, Example, a flask I use to cast matchplates in is 18x48, 5 over 5 . That flask is large enough so that...
Thats true, when pouring certain types of large castings I will clamp down the cope to the drag, and also use weights. "Bind it up and strap it...
easiest weights to get are 30 lb brass ingot. They are small with a lot of weight and are easy to position, I usually use two to a mold... Get 'em...
The open clover leaf design will let the weight be moved around so the pouring basin can be exposed to pour while still giving good weight...
Pressurized Gating is tricky, the math for the metal flow has to be very good. And a good layout is difficult as the parts will be at different...
Sweeeet!
I believe you! I an aluminum man. I tend to group all red metal as brass. Even silicon bronze.
looks like brass. I make a similar part in aluminum. Mine is a housing, gets machined all over. Goes to Koch, chicken processing. Don't think the...
Oh yea, that'd work....work good
Be hard to draw the pattern without draft in there
another look at you images, I think if you took the two casting that are coming off your downgate off, it may clear things up for you. I am...
the green sand core...attention to draft, 5 to 7 degrees inside. You will want to split the difference in order to hold closest to...
my hands are shaking some, hard to get a clear image. The runner is 1x1 inch w/basin in the center of the runner. 8 impression,a 3/4 inch spru, 2...
Looks like the metal is not filling as even as it should. Really a bad idea to pull an ingate of the spru basin. I made a rough drawing of a...
