Compact brake/bender

Max only hides when fly Fifers visit, even the honorary ones

Crikey, I am honoured; sounds like I've been promoted from hipster* to honorary Fifer!

* Funnily enough that same window (the one in which you saw the reflection of that shirt some three years ago) shattered again the day before we went up to Aviemore for a week, just the outer luckily.

 

[Hood]

Aye but a fly one.
Surprised the window lasted so long, must have had years of stress built up in it.

Measured my press when I was down at the workshop and I think it would be suitable for one of the brakes that @Robert Weaver has and they are not as expensive as the other one I saw previously so may consider getting one of them.

 

[gaz1]

Aye, saw them and thought they would be good but bit more than I wanted to spend and the press I have needs a new pump so that would add to the cost as well so...


Thanks for the info, know nothing about tonnage required so looks like 5mm would be a it ambitious I can easily bend 3mm on the folder I made but think probably only about 75mm is the widest I have gone but I suppose folding may be a different thing.


Are you @gaz1 in disguise

since you mentioned me

That three in one thing I have uses the top roller and cam via link arms to raise/lower the crop/bender. Simple way of getting even pressure on the tooling.

USB powered, nice…

For 5mm stainless you will need a vee width of at least 8x plate thickness, so at least 40mm, for that vee width the tonnage requirement for mild steel is 400 tonnes per mtr, stainless will be higher, so for your 100mm strip is 40 tonnes,
The wider the vee the less tonnage required but the bend radius will increase, it really is a job for a proper machine, something home made is not going to do it,

I think you are off by a factor of 10 @Paul. - my gut feeling was a standard 10T Chinese press with a brake adapter should be able to do this and I ran the figures and for 100mm wide strip of 5mm thick stainless came to 6.7T which is likely to be far easier for @Hood to achieve with something like the Swag offroad brake kit and a cheap hydraulic press.

I would love a proper brake but no room and I mean absolutely no room @Tangledfeet will testify as to how cluttered my workshop is.
I need something that can be lifted easily so I can store someplace and be pulled out when required.

If you are after something really small/portable then this came to mind;

HHB-800 / HHM-200W Bracket Brake

HHB-800 / HHM-200W Bracket BrakeHydraulic plate bender for bending steel and aluminium brackets. Automatic high and low speed foot operated hydraulic pump leaves both hands free to set up your plate. The high speed circuit means fast engagement of the too

Yes you are correct, the decimal point was missing in my calc and I hadnt noticed, your figure for stainless is spot on, apologies to all for the confusion. I ll give myself 100 lines, must pay more attention!.
