Eavestrough Enigma

It's time to adjust our gutter machine. Things aren't quite running straight.

A little under a sixteenth of an inch out in four feet. Very bad.

Where do we begin?

These things are complicated - adjustment upon adjustment for adjustment.

Rows and rows of shiny little wheels. Doesn't that just bring out the tinkerer in you?

First step: make our mechanic think he is on vacation.

The drive system, with which we are not qualified to tamper - but then, we aren't really qualified to tamper with anything in this machine. Viva la Unscrewdriver!

Part of the wondrous and incomprehensible lip forming box.

All four exit drive roller clearances must be carefully checked. The manual doesn't recommend more than 1/32 of a turn at a time on the adjustment bolts. Very sensitive.

The final metal mangling mechanism - it puts the bead on the back edge of the eavestrough.

"Any straighter?"
