Started out today(after church) by assembling the DIY4X Competition Dash.
This thing is as cool as I remember it. I bought it 4 years ago, in the spring of 2022. It’s been hiding under my workbench in my garage ever since.
I had to move my tubing bender so I could use it, and saw it under there.
I thought “you know what? I’m gonna install the cage B pillars through the dash, I might as well assemble it, so it’s ready when I need it.”
Took about an hour to assemble.
Then, moved on to start bending tube.
I’ve got B pillars already as part of the Competition Engineering cage kit I bought several years ago.
Problem is, those B pillars are made for a single center seat(read: single center seat, C series pickup)
That’s not me. So, here I am, bending up an upper hoop to attach to the rear hoop I already installed (after widening it about 10 inches) so it would fit the full width of the cab. After that, I can cut down the B pillars I already have to attach to the upper hoop. I’m going to have to use a hole saw and drill a couple of 2” holes near the outer corners of the dash to run those B pillars through it down to the stand off boxes I built

Whining and complaining…
When you don’t use your tube bender for a while you forget how much math you have to do to get stuff to work out correctly. I had to sit and stare at stuff for a bit.
Mess ups are expensive as tube isn’t cheap like it used to be.
Plus, this bender has a learning curve concerning its use. I’m covered in pinches, bruises, and small cuts.
Tube bending
CLR = Center Line Radius
Whatever CLR radius is add that much distance to length of flat in-front of bend. That length may be incorporated into any length needed in-front of the bend.
Length = (π × CLR × Degrees) / 180
2.5 CLR
2.5 (CLR) x 3.14 (pie) x 90 ( degrees)
/180
= 3.925” or 3-15/16”
3.5 CLR
3.5 (CLR) x 3.14 (pie) x 90 (degrees)
/180
= 5.495” or, 5-1/2”
4.5 CLR
4.5 (CLR) x 3.14 (pie) x 90 (degrees)
/180
= 7.065” or, 7-1/16”
6.0 CLR
6.0 (CLR) x 3.14 (pie) x 90 (degrees)
/180
= 9.42” or, 9-7/16”
