Making Applied Moulding with Cove
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.WhyDi
A table saw has the ability of moulding shapes that could not be easily machined on the spindle moulder and the following document shows how making applied moulding with deep cove but keep in mind that sawing such way requires you to be fully aware of safety issues. The purpose of all saw blades is to cut lined up with the workpiece and coving makes the blade working improperly. From there the much waste cleared before
coving the more safety and I start with machining non-through cuts as close as possible from the final cove. As you may see below the
infeed roller and the
wheel pressure module guide the workpiece whereas the
see-trough over guard prevents my hands from going over the blade teeth.
With nearly all the waste removed and slight passes related to the angle, the workpiece goes through the blade as much as needed to shape the cove. In the below arrangement I just have to feed the wood before the working tool then the
power feed unit pulls the stock allowing for smoother cut and safety as well. The left and top guards are not really required but they remind me I should never approach my hands from the teeth. I need that from time to time.
With the cove shaped it's time to adjust the existing rabbets. Not much material need to be removed, so the
rip fence in height position and the regular push stick with the wheel pressure module enable for enough accuracy.
The same table saw arrangement with the two
carriage hold-downs here used as blade guard make the chamfering and trimming operation more comfortable.
Finally the ripped workpiece gives two applied mouldings. Due to their shape and the inability of each to keep stable on the table when gliding along the fence the cut has to be performed once and right in the middle.
