We're trying to improve some cedar lumber (1 1/4 x 4 nominal, 1 x 3.5 actual) processing that is used on an outdoor gardening product. The volume is increasing (you probably know why!) so the labor is becoming an issue. Basically, sanding is the bottleneck in this whole process (has to be cut/drilled/bored/sanded/stained). The boards form a flat frame and the ends of some cuts (straight 90 deg made on a chop saw) need to be a bit "bull-nosed". They currently do this with a fairly long horizontal belt sander since they also need to sand the long sides. Bottom line is it takes time and doesn't always match up perfectly.
Here's my question concern: I think routing would be a much faster and more accurate process for curving the top and bottom ends (and one corner) of the cut ends, followed by a quick rotary "flap wheel" sanding that we've verified can do the edge sanding much quicker and "good enough" over the belt sanding. I am not an expert router for various materials and was told that the cedar lumber can sliver-out/splinter a bit, even with carbide router bits. Can anyone give me a recommendation on improving that process so that a router could be used, or in there another process that could quickly and easily make the rounded corners as shown in the photo (note that the raw end is factory cut, not from the chop saw they use which would be finer-cut).
One other question: if a router would work (or similar tool), is there a company that could make a custom bit that would cut the top and bottom corner in one pass? The could also turn it 90 degrees to put a radius on the outside corner. Note that since this is for outdoor products that sit in a garden, they don't have to be "perfect" like a picture frame or a cabinet door. "Good enough" is what we need. No splinters, reasonably consistent process, etc.
Thanks,
