- This is my review of the Grizzly T27978 - 50-Ton Air/Hydraulic Shop Press. I purchased this press and plan to use it as a press break. For more information on where you can purchase one check out Grizzly T27978 - 50-Ton Air/Hydraulic Shop Press

I've been tossing around purchasing one of these presses for a week. You have helped very much. THANK YOU!!! Awesome Video!
also the blocks are probaly sent soft so hobbyists dont turn them into grenades
Great demonstration! Thanks for the video! Thumbs up!
your gauge is in METRIC tons. so, 45 metric tons is almost 50 SAE tons
Man Richard your shop is getting cooler and cooler 👍
Thanks! You and Damian need to come over some time and do some forging! :)
Fantastic comprehensive review
Glad you liked it!
Can you tell me the type of C-Channel they used for the carriage and top part? The height, width, and web thickness. I am planning on making my own press. Thanks!
Thank you for your video. This thing is, as we say in Aust. 'not worth two squirts of piss!' What a waste of one's hard earned money. Many thanks for your appraisal. Is there a sticker saying 'Made in Hurry'? I certainly won't be in a hurry to buy one.
Good review. Electric over hydraulic is the way to go with a 10.000 psi pump with hand control and foot control.
Looking at the effect on 1" steel, one can have an awed appreciation for the engineering behind a heavy equipment semi-trailer.
Maintain the good work and bringing in the crowd!
Thanks for the video.
Looks like I may need to rethink my 50 ton air assisted bottle jack forging press.....
Great video ! Do you think overall a 20 ton press will it be enough?
for most things yes but i"m happy that I got the larger 50 ton press even though it only ended up being a 45 ton press. I have some future plans to beef it up a bit. :)
At those kinds of pressures it's probably a good thing it's slow.
👍Nice press
I just purchased a very similar press and the manual clearly states that the pump has to be filled and bled before using it. I don't know if you did that but that ratcheting sound might be air pockets resonating through your lines. The fact that it bends your bed plates proves that the machine is powerful and that you are simply abusing this equipment. The press is engineered to press on material that will move under the load applied by the ram. The bed plates are mild steel so will bend and not shatter, otherwise would be extremely dangerous. You not only bent the plates but the bed as well.
I am a machine builder/ fitter by trade for about 30 years and have worked with everything from 1 ton hand presses up to 200 ton hydraulic presses. Respect all machines for what they were designed to do, maintain them and always be prepared to make your own improvements if necessary. When I got this for my home shop I fully expected to modify it, I paid about the same as you did and am very happy with it.
Your negative comments on this machine are unjustified.
I didn't think I was being all that negative. I'm a professional machine designer. I design presses, custom machines, and lights out robotic cells. When I design a press I do FEA to ensure it does not not experience plastic deformation. The bed plates could be 4140 PH and they would be 3x stronger and still never "shatter" I realize for the price I paid I'm not gonna get 4140 PH bed plates. They could have used tube steel for the press bed instead of C-Channel.
The fact that their own press bed that they designed when used with their supplied bed plates experiences plastic deformation is a total engineering fail! As a machine builder I would think you would agree with this. Unless you work for Grizzly or something...
Also I do still like this press. I've made other videos about it that say as much. I have a whole playlist built around this press...
Sooooooo, why wouldn't you rewind the cable so that you can spin it the other way to lift it?
I did end up doing this.
LOL I was wondering the same thing as he was complaining.
it sounds like your air setup isn't putting out enough flow ie cfm
Yes this was part of the problem. I removed the regulator and it helped. I also had to modify the valves on the press. It would not fully seal shut.
Use the hand pump you'll get there faster that air over hydraulic unit is garbage on all of these

I have that exact same machine, except I paid $1500 for mine, that didn't include the the bottle jack, I had to drag it home myself. As for the cost of an actual punch press machine, you're probably looking at closer to 5k for a very old machine, that most likely runs on 550 v 3 phase, which is industrial, most shops won`t have that, so you would most likely need a phase converter another $1500 plus shipping for a decent one, then you have to hire a machine mover, easy another 2 k, then you have to set it up, you may need a thicker floor with a rubber mat.
This is a chinese el cheepo, but it's a solid little press, we use it daily pressing steel parts, for what it is & it`s low cost, there`s nothing to complain about. You will need to modify it to what you need, it does have its limits.
You don't buy the cheapest Hyundai car, believing it`s a top of the line Mercedes. You want a digital all hydraulic cnc press, your into hundreds of thousands.
It`s slow, the cylinders will leak if you use it hard, in less than a year, you buy a new one for $130 ....
I`m sure you could build a better heavier duty press yourself, cost you way more just doing that. You can go buy a custom sized piece of tool steel, or you can scrounge something from your local scrap yard for a few $$$$ .... It's all relative
Of course you bent it. You cant put that kind of pressure over such a small area. Spread the load.
Puts hand out to pad the metal object about to hit him in the face!!
Well when you put it like that I sound super stupid. hahahaha I noticed this as well when I was editing the video. I wondered if somebody else would think the same thing.
Take that boat winch off there and replace it with a worm drive winch that sells for about $10 more. Lots more power but slower of course.
great idea!
It's really unstable. I think it should be more stable if your not going to lag it to the floor maybe find a peice of heavy steel plate big enough to make it stable and stich weld it so it can sit flat on the floor.
Yes I totally agree. This is something I was going to do for a long time and has not yet got around to doing. I should really move it up on the priority list
Awesome, 1st Comment!
jesus christ this guy is gonna seriously injure himself
Well so far so good.
Looks like a pretty nice press but it can't help it if it's subjected to fantasy expectations. So you deliberately bent a nice new tool
by doing something that no one would ever do to one of these in real life? Sorry I stopped here.
Hey if the speedometer on my car say 160 I'm gonna see for myself if it can get there...
I was thinking the same thing. Eaven if I was to ever need all 50 tons that this press would actually do I would never concentrate all the force dead center of the table.
I run a 160 ton press daily there is just some stuff you dont do.
This is very dangerous what you do without safety PPE
This press is dangerous. I have a Stenhoj 25 with none of the described problems.
Hahaaa
Good or bad, you aren't taking it back. Just an excuse to make a video and pick up a few bucks having others buy one.
yes that makes total scene. Buy a tool that's over $1,000.00 so that I can make $20.00 in advertising revenue and deal with illogical trolls... It's clear that you in your infinite wisdom know all the motivations of all the people in the world that you've never met. Thank you so much for watching my video and donating $.10 to help cover the cost of this piece of shit press that I use all the time.
It's nice to see that people spend all their time watching content they don't like to make them selves feel good about the rest of their life they don't like.
100000lbs of force and your talking shit that it bent?
Bk
That whole SHEBANG is a pile of garbage and dangerous as hell! And using your hand to shield your face is NOT SAFE? Where is your common sense???
Harbor freight 50 ton is heavier
Send it back minds harber fright keep it away from children’ 500 pounds could heart someone bad if it fall on them
This guy is a triggered snowflake; just what did he think he was going to get for$750.00? It's well known that Grizzlies cheap stuff is a kit in a box. Potentially a good starting point, but it'll need work. One of my neighbors swears by their top end woodworking equipment, but freely acknowledges that it costs more for the results.
Thanks for watching.
