Might be in the market for a hydraulic press. Just wondering what other members use? Is This one any good or is a Sealey a better bet? I notice there seems to be no adjustable table on the cheaper one!? Anyone use a powered press say with an enerpac pump?

Well better late than never. I've eventually decided what press I'm getting and ordered it. Firstly I wanted something that didn't take up lots of room so a floor standing press was out. I wanted something strong enough to make up to 2lb rocket motors so an arbor press was out. I have heard that H frame chinese quality are a bit dubious and can flex so I decided on this C- frame press

It seems from reading posts on passfire and elswhere that this is one of the few chinese presses that come close to its 10 ton rating. Its also small enough to store away although is not light at 144lbs!

The fist thing that struck me was no table height adjustment, though there are ram extensions that come with it to counter that problem.
There is no guage with this press but I understand one can be fitted in line with the cylinder. Any advise on which one would be most welcome. I'll now need to get a blast shield so will 12mm lexan do? or thinner sheets put together?

Here is a link to a guy that uses this press and has a power pack added (something that is on the cards as finances allow) I'd like some input on this to please.

The press in the vid has had about 6" cut off the foot too to enable the blast shield to be fitted better and reduce some weight.

I think it looks very sexy but then I'm quite sad :D

The Sealey is the one i use, i like the way the ram slowly retracts when you let the pressure off. It was also easy for fitting a blast shield, mine slides behind the mainframe.

Who tests the tester.

Dave, as far as I am aware that press was sold by harborfrieght in the USA and is now discontinued. I found the ebay link and its the only place I can find these presses now. I have no doubt someone will come back and show me a link at half the price.

If you are a member of passfire there are quite a few threads about it. If you search for 44811 which I think was HF stock code it brings it up.

I think the power pack is gonna be expensive but I need advise on this if anyone can help.

Just an idea on the blast shield (don't have a press but would like one) how about 10 or so layers of 0.5-1mm thick mild steel as a blast shield, I wouldn't know the exact weight but a good stand would hold it easily, and for the 60-70£ it might cost you it would be a lot stringer than lexan? Althogh I don't know what lexan is... But it's proven more layers can take more impact if I'm right?? I hope people have some feedback on my idea on what they think

thanks
George :)

Lexan is a brand name for polycarbonate sheet. Steel might be a bit of overkill and make it even heavier!
Also I like to see the rockets before the bits come flying at me :blink:

The Lexan shield is used because you can see the process through it, so you are not tempted to look round it!

IF you feel the need to use steel or remote operation, then you will have to find a suitable remote monitoring system and learn how to operate the system from a CCTV screen.

if your press was standalone then the mild steel would be an option, but if portable i agree would weight a fair bit, although there is never too much overkill on safety when pressing whistle mixes or anything of the sort....
and if you feel the need to look round stop pumping, wait for it to dwell to be sure then peep round for a glimpse second to see how its going, or as discussed before using an angle grinder cut a slit through the left hand-right hand side of the sheet metal for a viewing slot, only 1cm thick (not the center as it would cause weakness in the overall piece of metal), and put a piece of polycarbonate plastic, the poly carbonate would be reinforced because 1cm slot would allow it to "bend" slightly without splitting, and anyways the peep hole should only be used for a few seconds anyways....
