Epilog Challenge 9


This is my instructable about making a press. And some usefull attachments for it.

Instructable includes plans. Structure is tested with 6 ton jack.

With 6 ton jack, frame keeps it shape without any bends.

Welds are made with 3.25mm Esab ok 73.15 welding rod. I used 110 a current.

I made my press with little different way.

Jack is placed down:

It lowers the center of gravity and places the handle at a height where you can bare down instead of pulling down. Its easier to make different attachments to it, for bending, rolling etc.

In the upper beam of the frame is extra supports made from 20 and 10mm rods.

Those are just for preparation. If i ever need to use bigger jack, i can place it up in a traditional way.

Possible situtation might be stamping cups or something similar.

Video shows the process:

Video tutorial.

Materials are mentioned in plans.

Tools that i used:

Chop saw:

Angle grinder:

Stick welder:

And some misc basic tools.

Step 1: Cutting.

I cut the parts using chop saw.

Cuts can be made many different ways, usually i use angle grinder.

But sometimes getting right angled cuts are important. In this case its not absolutely necessary, makes building much easier.

Plans include measures for the parts.

Rips that goes inside upper and lower beams and "sled" are made to size 52mm. Thats 2mm wider than is the vertical beams measure 50 x 50 x 5 mm. That makes building little easier, because welding leaves allways disortion.

Step 2: Building the Beams and Sled.

I started building the frame from the beams.

I clamped the part nro. 5 against my "welding table"

Then i tack weld ribs ( part 7) to right angle. After that i clamped sides ( part 3) to the ribs, and tack weld them.

Make two similar beams, for up and down.

Sled: Is made with the same method. Put after tacking i weld all parts together. In outer ribs ( part 7 ) i left outer side unweld. Welding those outer welds would bend the ends from the parts 2, and make it fit too tight to the frame.

Step 3: Building..

I clamped vertical beams to table.

Then i clamped upper and lower beams and checked that thr stucture is right angled.

Tack weld the feets and other missing parts.

Step 4: Welding.

After everything was tack weld and in the right place, i started welding the stuctute.

I weld corners firts. I use method "Out to center, or center to out". I make welds with the similar way to both sides.

I weld ribs inside the beam first, after that i weld longest welds in the sides of the beams. Specially with these kind of welds is important that you don't weld sides in different directions. Otherwise beam gets twisted.

Easy way is to "share" weld in two parts, and start in the middle, then weld both sides out. Welding makes allways disortion, this way its symmetrical and easier to straighten if needed.

I used stick welder with this project. Tack welds with 2.5mm rod. (90A) Welds with 3.25mm (110)

Used additive was Esab ok 73.15

Step 5: Support for the Jack

Because jack is placed down, this structure doesn't need any springs to pull it down.

Only extra part was a simple support under the "sled"

Support has a hole with the diameter of the jack.

In use cylinder goes trough the hole. Sides of the hole leans to cylinder and this keeps sled straight.

Step 6: Finishing..

I removed splatters using angle grinder and flap disc.

Then i brushed surfaces with steel brush and removed grease with thinner.

Finally painted it with spray paints.

Result is balck with little red on it.

Step 7: Tools...

I made this press, because i wanted to bend thick flat bars.

So, obviously i made first tools for bending.

Tools are made from:

10mm steel plate, 3x 30x 30mm L-profile, 40 and 20mm axle

Clearance between rods in the lower facing is 15mm. Radius of the rods 20mm.

Its for bending over 90 degree angles to plates between 1-5mm, or 90 degree angles to plates between 1-10mm, it also works as a facer when straightening bent bars.

Blade with the opening allows me to bend U-shaped objects.

Plans for two tools as an example.

Video shows the use.

Step 8: Closer Look..

Tools are attached in a very simple way. Claw in the one edge, and clamp pressing other.
I planned to use magnets or clips instead of spring clamp..

Magnets would soon be filled with metal dust, and mechanical clip might break.

One dollar clamp is easy to replace and does the job, was my solution.

This instructable will continue with the couple different attachments and tools inc. roller bending attachment.

So. Thanks for watching! And stay tuned.

Ps. Remember to vote, if you liked.

Pss... If you see instructable robot sticker in some object on my videos or pictures.

Then you can find instructable about that object in my profile.


Step 9: Pipe and Rod Bending Attachment...

Simple pipe bending attachment.


Surplus steel, nylon replacement heads from the dead blow hammer, bolts.

Video shows the making, but i will update more info soon.

It can be used to bend pipes and rods to 12mm diameter. ( grooves on the dies are with 12mm diameter )

Same idea works with bigger pipes too, radius of the center die needs to be bigger than this one tough.

Next add is a roller bender.

Step 10: Improvements...

Latch that holds the upper die. Little more "professional" looking than using clamp.

Because latch works like a hinge, it works even that i have used 10-12mm thick plates when i made my die set.

Made it from scrap metal that i had, so its not very beautifull. But it works great.

Video shows the use.

    I'm impressed, very good! I have an observation / question your design has the press acting along the plane of the press on the tools you have made and use with the press. I have noted this is similar to many presses of this type. The observation... This limits the width of the project you can complete on the press. The question ... with the size of the "tools" you are using with the press, without the "hook" attachment, could they be rotated 90 degrees, and be able to work material of a wider nature?

    Yep. That's a really good point. It would be very usefull. I will test it. But it should work. I actually would have needed that option many times. Thank you very much!

    I would be worried about bending the ram on the jack if a load was not centered on the press.

    Yep. But it can easily to be seen if it tilts. You need to center the load anyway, is the jack up or down.

    Very very cool build. If the right job came around I would definitely consider using these instructions.. Thanks.

    The link to the video does not seem to be there?
    Nice build. Been on my build list for ages, so I'll be taking some of your hints on board too.

    I'm curious, what kind of drill / mill press is that, which you used to bore the holes in the Flat bar? Thank you for the instructable!

    Its Evolution evo mag 50 magnetic drill. Here's some pictures of it.
