Shoreline nailed it pretty good except for a few errors
# Replace beers with a cans of Bourbon
# Replace hacksaw with 5" grinder & thin blades.
Another helpful trick is to place a bottle jack inbetween the frame rails to slightly pry open enough room for either hacksaw blade or grinder disc to fit through.
Just spread slightly & it will flex back
And be careful when putting parts in a press, I have had to repair a few frames that had the swingarm pivot gussets on the frame crushed from too much force.
