btw... has anyone actually used a recipro saw for entry through a roller door? does it work well?
Many years ago and the roller door had collapsed. Needed to cut into moveable chunks.
Needed to support the metal underneath to allow saw blade space underneath and also support my weight as the operator safely. Then had some others assist to ensure metal stayed firm.
Was difficult because blade kept jamming in the joints. When better access was made, swapped to the quick-cut (motorised saw) with a metal blade.
Unsure how it would work with a standing roller door. Danger of metal loosening as you cut, then jamming blade.
Also, what would you use to make the hole to insert the blade into ?
My best guess would be to locate the locking bar on the roller door and cut that. Then you can open the roller door if the cuts dont jam in the runners ?
