Is it possible to do without squishing the tube?
Test to see if you can get away with the tube filled with sand before bending You may or may not get away with it.
Chech out this thread:
Thats what i was thinking because i have bent square tubing like that before.
I have heard mixed results from this
Because sand got brought up you might want to take a look at this.
i would never recommend this on anything that might save/ risk your life.
Sand bending tube looks like a ton of monkey-ing around.
But you would trust your life to a 1" tube bent in a 1.75" die? Obviously not. But if you are going to pack it in sand using the technique in that article might help you out (namely using washed sand and a soft wood slapper). It might also help you bend thin wall 1.75" tubing in your thick wall 1.75" die to do exhaust work.
get a 1in die
This is how tube was bent before they created mandrel benders. They also use this method in water jacketed exhausts.
I would do that if i would use it more than twice. All i need for is to make 2 bends to make a new light bar for my car. It just didnt seem cost effective to buy a die thats only going to be used twice. I have started the light bar and will post some pics after i make the bends.
Keep us posted. I'm interested to see what will happen
So, how did it come out???
Been there done that, sand bending sucks.
Came out really well i will get some pics of it tonight and get them up asap.
I hope it works for you but in the past I had it flatten out a bit but I did not use sand. I just cot a die for my model 4 bender for $200 and it is just one of those sizes you should have. Sizes to have are 1", 1.25", 1.5", 1.75" and 2". I just need to get a 1.25" die and I will have a full set, then I am thinking of picking up some square tube dies.
bringing back this older thread to add a "trick" that was not mentioned
some time ago i needed to make some clean 1.25 bends in a hurry but i had only a 1.5 and 1.75 die.... so i bended a scrap section of 1.5 x .120 DOM , removed the bended tube , split it in half with the plasma, cleaned it up, and bingo; i got myself a dirt cheap 1.25 bender insert .... works perfect for that dimensions that i dont use very often
Hey thanks for bringing this back up i had pictures but couldnt find the thread. I will have to go out in my shop tomarrow and get some new ones with the lights mounted on it.
I mentioned that in this thread....which I posted the link to on the first page.
Here is my post from the other thread:
That trick works great. I learned it from Dave Turner.
