If you have ever been into electronics in any particular way the problem often arises at the end of a project the

enclosure What the hell am i going to put all this in !

Some peoples standards are different to others and some are quite happy putting their projects in any type of

box and believe me I've seen some things online verging from a pc in a cardboard boxto amplifiers in cigar

boxes.

Now don't get me wrong this can be well implemented at times you only have to look at the Cmoy Mint Amps

housed in an Altoids Tin to see a good implementation.

There are quite a few nice off the shelf commercial chassis's available such as Hammond

Mfg extruded aluminium series but they are very height limited you aren't going to fit any type of large

transformer in there .There are many others some from EBay, some of the Chinese chassis are great but factor

in shipping and tax and your soon racking up 100 + only to have to modify it and this is where my journey

begins.......

For many years i have wanted to make a my own PC case but this involved bending metal and i have to say i

wont bother starting a project if the end result doesn't look professional .

You have only to look at Cygnus X1 ,a work of bending art.

Earlier this year i decided to start a new D.I.Y Audio project, i wanted a small yet powerful amplifier for the

PC to run a pair of Q Acoustics 1010i bookshelf speakers. I decided a Gainclone was the way to go and

decided on a LM3875 Classic kit f rom Audiosector.Peter is a great force in the DIY Audio community and is

a master at making simple yet beautiful chassiss as well as the bits inside :)

Some of Peters genius artwork ..... what your looking at is a 2x68watt amplifier!

So the kit was built and the prototype chassis was made to house and tweak the layout after a week or so i had

the layout down and i knew the dimensions of the chassis that i required .I already had decided that i would

need to make my own chassis and the prospect of bending aluminium arose yet again.

The testbed prototype ready to be re'housed..........

One thing i knew was that i wanted perfect bends and bending 3mm aluminium wasn't going to be easy not

only that but actually getting precise bends and keeping everything square would also be a challenge you have

to factor in how much material the bend will use and where it will end up. I thought about this for a few days i

even looked around for a brake press but they were either too expensive or feeble even some of the larger ones

could only bend thin gauge metals .

I have a bit of a motto if you cant buy it or borrow it then make it! and this is when i thought i would

make my own bender .I rang my friend Mick as i remembered he had some angle iron floating around but as it

turned out he had used it .As i couldn't wait and had a look around for materials i had lying around when i

noticed quite a bit of 38mm bamboo worktop off cuts ,so i decided this might just fit the bill as i wasn't

bending steel the impact on the edge of the backstop would be a lot less

Heres the result of an afternoons work..........

I'm not going to get into the construction of the bender as its pretty self explanatory and the lengths will differ

depending on what the size of sheet you need to bend.

One of the most important parts are the hinges these will take allot of force during the bend and its pretty

critical that there is as little play as possible as this will influence the quality and tightness of the bend .I used

some 4 inch heavy duty stainless hinges because they were the best i had around .One of the bonuses of the

38mm plywood was the fact that the hinges could be screwed in place i didn't need to bolt them through the

base and swing arm.

The other bit of advice is to run the face edge of the backstop through a table saw i used a angle of 5 Degrees

this is because when you bend the metal you usually want 90 Degrees and when you hit 90 the metal will

want to spring back a little so the idea by adding an angle 5 degrees past 90 is so that you can bend past 90 to

allow for the spring back so when you release the handle the bent angle will spring back to 90 not 85. (This

isnt set in stone you can have less of an angle or more)

The two M10 bolts in the top are to clamp the sheet between the backstop and the base, The backstops bolt

holes have a slot cut in them to allow the backstop to be slid back to allow for the thickness of the material to

be bend .

See how the face of the backstop slopes backward slightly..........

Time to bend or nearly.

So we have the bender but we aren't finished as there is another trick to getting the perfect bend and this

involves making a score or cut line on the sheet where you want the bend to start for this you will need a

table saw with a blade with as many Carbide teeth as you possible and preferably sharp :).Aluminium cuts

surprisingly easy with a decent table saw especially when you use a blade designed for cutting non-ferrous

metals ,but remember if it grabs it wont be as forgiving as wood to you or the saw.

Make sure you take precautions with guards and safety glasses e.t.c and of cause i take no

responsibility if it goes all horribly wrong it is up to you to gauge your ability and the risks

involved when following these methods.The guards were removed from the photos for

clarity!!

Here we can see that the blade it set at about 1/3rd of the thickness of aluminium this figure will depend on

the thickness of the material to be bent.

Here's a piece of aluminium 3mm thick. (Its a good idea is to practice on some scrap first..........

10/32



So we have the depth set on the table saw and the lines marked on the material to bend..........

11/32



Once youre happy with the depth now we set the saw table fence to the first cut. (A little note here using this

method of cutting the line removing a third/half of the material will give perfect 90 degree sharp inside corner)

if we just bent using the bender you would end up with a radius on the inside as well the outside.

Here you can see the channel made by the Saw blade..........

(A tip here is if you are making a U shaped cover/lid for something you would have cut 2 lines in the sheet

so you would have a side/middle or top/side sections, if you want the middle(top) section to keep the same

width as the marks make the cut on the other side of the marks towards the sides that way when you bend it

you will maintain this measurement and any excess can be cut off the side later by placing the bent piece on

its side in the table

Saw.

Here i rotated the sheet over to duplicate the other side..........

Here you can see that the backstop has been slid back and the bolts tightened to allow for the thickness of the

material.

The edge of the cut is exactly lined up with the gap between the edge of the backstop base and the swinging

side. The other cut edge is directly in line with the bottom of the backstop.

When we start to fold the whole cut line will act as a weak point and the bend will follow this path

exactly till each cut edge meet together producing a smooth square bend.

If you didnt quite get 90 degrees try push the piece slightly passed 90 to allow for spring back .Now i just

turned the piece round in the backstop re-clamped and bent again..........

Few Extra Tips and Bits

Get a good long stainless steel ruler preferably with 0.5mm increments for precise measurements and straightmarking

http://2.bp.blogspot.com/-4q_kcgxeDMM/TvXDvg5V_mI/AAAAAAAAAfA/SJYSu7S6uco/s1600/pic+5b+%2528Large%2529.JPG



Get a Sliding Engineers square or Combination Square you will use this constantly from everything from

checking for square lines, transferring lines also checking depths and marking centres for drill holes

Get a pair of Digital Calipers you will never look back !

http://3.bp.blogspot.com/-cfQf_C8sN24/Ts44P5uI5FI/AAAAAAAAAH0/32cY01pswBI/s1600/1269410309113_hz_myalibaba_web7_1543.jpghttp://3.bp.blogspot.com/-W3vrm5bdZ84/Ttth61YB4pI/AAAAAAAAAN0/VxebMT-6w74/s1600/Steel_ruler_closeup.jpg


25/32


The finest permanent marker such as Pentel NMF50 (my favourite) or the Sharpie Ultra Fine will draw 0.5mm

lines on anything ,or use a craft knife to mark soft metals such as aluminium.

26/32


The Finer the marks the more accurate your bends and cuts will be .A 2mm line with mean you could be out

by 2mm off square or that hole you drilled just wandered off 2mm doesnt sound like a lot but when yourdrilling four holes to mate up to another piece it wont !

Thanks for the nice tutorial. Here's an idea to try on your next project.

Would tilting the saw blade 45 give you a more seamless bend?

This way, you would take out a wedge instead of a channel.

Opps, Illustration below works better with a monospace font.

Rupert Hirst - Koogar 8 December 2011 08:46:00 GMT

Hi Bill

Yes a 45+ side cut would give a better bend and its the right way to do it. My way is a bit of a hack plus it

gave me a larger radius on the outside corner which looks nice.

Also you need an angle slightly more than 45 to allow for an over bend so when you bend the line it will

spring back to 90, if you have to force it you end up distorting the flat sides.

I was hoping my DIY CNC machine would have been finished by now this would enable me to cut the entire

piece flat in one go including the holes with a V groove for the bend lines using a V Bit.

Good idea though will have to try it next time :).

Thanks

Rupert

Any alloy bend that has to take any load must not be cut, it will crack & fracture. Thicker sheets or harder

grades need to be heat-treated i.e. annealed, before working it.

@Deadly Derek

mmmmm, I think you missed the point about it being a non load-bearing application, unless you count the

downward force of gravity on an external case as "load-bearing" :)

But thanks, both, for your info!

@Deadly Derek

You are correct in a commercial application etc but that's the kind of comment that stops people from trying

things such as this. All aluminium will crack if it is over stressed in any situation cut or not cut and it is up

to you to decide the stresses involved. This is an inanimate object with no loading as is most DIY project

enclosures.At no point was i suggesting you could make a motorbike side car etc from this method at which

point you comment is totally valid :)
