Preparing the Tubes
Take the tubes out of the box
Sort the tubes into desired groups - keep stickers on to match to the BOM
Front Bulkhead
Floor Tubes
Trailing Arm Tubes/Rear Tubes
House Tubes (Dynamics Tabs)
Remaining Front Tubes
Prepping the Tubes
Clean the ends of the tube (interior and exterior)
Using an angle grinder with a sanding attachment, or an air tool with a sanding attachment
On the exterior of each tube, sand about an inch from the end of each tube (better to do more than enough)
Using a Dremel with the small sandpaper attachment or an air tool
On the interior of each tube, sand about an inch from the end of each tube (DO NOT TOUCH THE MITER)
Cleaning Set Up
Clamp a tube in the vice
Use welding gloves to protect tubes from scratching
Angle grind
Rotate
Finish Angle grinding
Assembling the Tubes with Jigs
Set up all tubes you can and test fit, and then feather if there are gaps
Coplanar tubes generally have decently accurate miters
If there is no gap or step
Tack at four points and then full weld between the tacks
If there is a gap or step
Feather the inside face of the miter
Feathering the Miters
Using a Dremel or air tool (preferably Dremel) on the inside face of the miter
Do not take off too much material
Guess and Check by feathering a little, then test fitting and repeat
Additionally Notes:
Use right-angle magnets to ensure perpendicularity
Use a magnetic digital level to ensure tubes are level
Specifically on the bell crank tube
Take pictures to document the process for next time and portfolio
