ok and thanks.
thx Magnus, I am familiar with princess auto ( to bad it's all closed right now ) this helps. I thought it was gonna cost me more then $2000 to do it which is why I haven't done it yet. But I like that figure a lot better.
Hello again, I just saw princess auto has a 2 stage hydraulic pump on sale. 9 H.P., 3000 psi, 15.2 gpm / 3.3gpm high, rpm - 500 -3600
I'm thinking this could work but will it work well?
That could easily work, though something smaller would be just fine (mine is only 2 hp and work extremely well). Do you have 220V in your workspace? You'll need quite a motor to properly drive that pump. If you're planning to use a large motor, a single stage pump may be preferable.
Check out these hydraulic calculators to get an idea of the size of components you'll need. Most people like a minimum of 1 inch/second but faster is better.
Thanks a lot Magnus, I do have a 220V hookup for my welder but I'd like to keep it smaller if I can. They also have a 5hp pump on sale but I can look for a smaller one as well. I just want to make it so I don't have to worry about my upper limits and of course...it needs to be effective. My goal when I started this knife making thing was to make a Damascus sword. That aint gonna happen without a press or power hammer cause I just don't have the arm. But I want to be able to make a larger billet. This helps and I will have to blow the dust off the ole brain and start learning about this.
Hi Forge, I have read this post over and over again and I think I understand what you did. There are a couple posts on Utube as well that explain this. I am gonna try doing it this way but I have a couple questions about it if you don't mind. First of all how big is the oil tank you have for this set up? Secondly, princess auto has motors on sale right now and the 1 hp motor I am looking at only has 1725rpm...is that enough or do I need to get over 3,000 rpm? And lastly...I am having trouble finding a 2 stage pump that only does 3 gpm. Everything I see starts at say 11gpm and then requires more power. Any ideas where I can get something like that or am I looking at it wrong?
