Swing Away Guard up to 150mm (6 pouces)
Preamble : I don't want to write another list of what each woodworker should know in order to work safely. Everybody may find what matters using a search engine with key words "woodworking safety". Albeit all these articles talk to the others and I would have liked to find someone writing : "for my own safety I try to..." which means many more people convey a standard point of view about safety without wondering anything. I avoid these kind of topic that lead to nothing most of time. On the other hand I get involved in every exchange that tend to explain why something would be unsafe et try to find out a better way. It's all about mental attitude and the last one requires the point of view to be argued. Nothing good nothing bad but keeping open minded
This swing away guard may be fitted on any planer-jointer with cutter block up to 150mm (here is another one
aiming 310 mm) but should never replace a bridge guard
. Take a look at the third drawing. At the end of the pass and for a while the cutter head remains uncovered. As a consequence push blocks are part of the guard and the operator should compel himself to feed workpiece with push blocks. As the operator feed the stock the top revolves and clears room then comes back to its origin.
Description : A hand lever releasing a holdfast would enable the guard to be set and removed without tool. A spacer would stand on the machine frame allowing the guard always the same height from the table. A machined track would guide the top with a minimum of rubbing. The polycabonate top would revolve around an axis and slide into a groove at the other end. You may find out how coiling a spring in that document
that would allow the top to automatically come back to its origin. Lastly a bolted angle on the top would stop to its start position.
