tube bender

[Nutz4sand]

I think I follow what you wish to do for the stop Baloo.

The only thing I can see an issue with it is it would get close.

But each tube size and thickness has different springback. So you might need a differet "stop rod" for each tube size or thickness??

Maybe not?

How about using a limit switch where your hyd valve is shown in your sketch  and a solonoid valve to dump the pressure?
 The valve could be right on the tank and save some pluming.

hi Rich

l did start off thinking about limit switches but over here the mains voltage is 240v which will kill you easily so if a wire came off  the switch and touched the machine l would be dead and whilst you guys might not miss me the wife would kill me if l did  that 

true l could use 12v solinoids but then l would need a transformer to get down to 12v and a rectifier to get to dc and it all starts getting more complicated and costly, a simple valve is $15
in all honesty l dont think l need a stop really for the amount l am going to use the machine, a big degree wheel and stop when it reads the angle l want will probally do .

what started me thinking about a stop was that the ram is to long really think it has 3" to much stroke so if l dont stop when the die is fully round then it will just bend something, fine if l am using it since l know but if l lend it to someone then its likerly to come back busted

Looks like you've drawn a thumbscrew on the stop making it adjustable. You should be able to move it, make a mark and go back to each mark when needed. If you check your bends with a protractor, make and keep a chart for each type of tube, thickness, and springback you should be able to make it repeatable.

thats what l was thinking, fix a tape measure on the bar and write down the numbers that the bends corresponds too

Dog seems happy with the outcome?

[Baloo]

spanner is always happy checking out what l am doing







there is actually 2 of them,  double trouble















and that collar slowed him down for a while



so l have a hydraulic power pack a big hydraulic ram and 4 pipes, and the only bit that works is the 4 pipes

Bummer!Cool dog though.

Real bummer BalOO.

How in the hell did that ram bend like that?  Did it bend just as you were starting a bend or at the end of a bend?  Like the ram got in a bind or somthing?

From the above where he says no wonder its so cheap I think he bought it that way.

That IS BS when somoene sells something like that and does not tell you first.

Hopefulley the blue pump you got may be good it may just have a bad coupler between the pump and motor?  That would still let it squirt fluid but do no real work. I dunno just thinking outloud.

Now if he was a LEFT handed fiddle player that would be UBER cool!

Right handed or not I'm impressed. I can't get my dog to anything like that.............lol

better day today, tried another power pack and it works ok, pushed the arms round to around 110 degree in one push in about 20 seconds, mounting detail is different though so l will have to cut the brackets of and remake
