This is a warts and all build, happy to share mistakes and boy did I make one today.................
Started marking and cutting out the center crossmember
( Note Old Skool build basic tools
)
Got the shape of the crossmember done then drilled holes and punched them out to be dimple died. In this pic the holes been punched no drama's. I then thought to myself I shouldn't dimple the hole till I have added the top and bottom plates and gussets to strengthen the crossmember......
Got a phone call, went back to the shed, for some reason I picked up the dimple die and punched the crossmember with it. Instant fail the pressure distorted the metal and just wrecked 2 hours of work....
At least with the exhaust bolted up the cats are tucked up near level with the bottom of the frame.....
