does anyone have any experience with a high quality finish such as that on gfrc fireplace mantles. I need a mix design. and some tips would be nice. Thanks in advance
hay ole slvr, whell, I'm trying to build a charcoal briquette furnace to melt aluminum. Saw the furnace you built on you tube. Nice job on both the furnace and on the production. Very professional. The furnace I am building is run on charcoal and forced air of course and it works real well. The...
OK, well I think I just hit the jackpot on this one. I called a local foundry that will basically teach me how to make a mold and then they will cast it for me into the mold that I make. The best of both worlds as it is the tooling and pattern making that is expensive and being a heavy duty...
BTW Compo, I'm using a hvlp compressor for the air supply. High volume, low pressure and capable of running all day with back pressure or no back pressure without any problems. I think that is an upgrade from anything I have seen online.
hey composite pro, I believe you are correct in all counts. I plan on buying a commercial crucible and the reason why is that the idea of having 10 pounds of molten aluminum splashing my groin is not going to happen. I don't want to be pulling the crucible out and have it break or something...
Castmetal, yeah, that visual right there is what I'm not looking for.
As stated earlier I have a phobia about that so thanks for feeding the monster Bwahaha
Hey composite pro, you are absolutely corect. Hardwood stands up to the rigors of drycast quite well. Combine that with the fact that I know a shopbot owner that could make that mould for me and it starts looking pretty attractive. I am really looking for an excuse to have to build a foundry I...
Will take your advice to heart and go slowly untill I'm sure of what I am about to do. Thanks for taking the time to involve yourself. I appreciate it.
I always TRY to contribute in the arenas that I am an expert in.
I'm surprised no opinions on this subject. seems like there is room for a bunch of difference of opinion on this one but I guess I just have to try it to see if it works. In the end, as long as I don't blow myself up and it works then it's all good.
I guess it all comes down to how well you like your feet eh? I'm kinda partial to mine but I think even counting that i've got a phobia of dumping liquid aluminum on my foot.
Hey Blacksmith, you may be on to something and as soon as I get my furnace up and running I will try just that. I'm finding out that you need to have a blacksmith shop set up to make all the tools you need or be prepared to shell out some coin. I think the ladle tongs and pouring irons are...
So after researching I have come to the opinion that Pearlite and portland cement make an excellent refractory with the major drawback being its inability to withstand heat much over 900 deg. F. If I am wrong about the temp please tell me. That's why I'm posting.
A major plus however is that...
Really? I think it is perfectly fine to offer whatever it is worth to you and fits in your budget. He's a grown up and can decide for himself.
I offered that suggestion knowing that the last job i used a compaction grouter on was for a school and ran $350,000.00 us
Nest bid up was twice that...
Ya know, thinking back on it we were right at 8 feet of water at high tide. water poured in pumps kicked on and problem solved. We had a basement garage, rather large with ten foot ceilings and I think it was about eight foot of water at high tide
Whatever way you go should include a permanant dewatering system to maintain nuetral pressure. We did this on a house in the mudflats of the Sac. river. Kikcked on a few hours twice a day. Foundation stayed high and dry for the most part on a bed of three inch rock. The water is pumped out as...
We installed a liner in a dump one time. It was handwork like you wouldn't believe. We had men on their hands and knees with trowels in hand picking rocks and smoothing. That job was Awsome and we made a buttload of money. yeah! I wish
