I am working on building a set of tower speakers and decided to use pre-veneered MDF-- I am saving learning how to veneer for another day. Anyhow, I bought a lock miter bit and had success setting it up to make a scaled down sample with plain MDF, but am not happy with the results. My router is underpowered and the table and fence work but are finicky. Pulling off this joint doesn't allow for any error.
I recently got a Grizzly 0690 table saw and the more I contemplated my next move, the more tempted I became to just make plain a old miters using the table saw and just hope I don't screw up the glue up. But I recently came across an old article showing the use of locked miters made on the table saw, which I realize is a fair amount of work but with my choices of tools, seemed like a better idea. The alternative would be to do a splined miter or something similar to assist in glue up. It will be four sides with bracing (installed using stop dadoes) so I really want to use an invisible joint (miter) that will fit together well for the glue up since I am notoriously oafish and not a fast worker when it comes to executing glue ups.
I'd appreciate any suggestions or insight from anyone have experience making these joins using similar material on the table saw as opposed to the router.
Thanks in advance!
