I have made a lot of jigs, well ....me n' youtube! I am a huge fan of William Ng. However, may years ago we had a wood working "jig" company about 70 miles from my house (Woodhaven) and on the way to one of my wifes' favorite shopping spots so I stopped in to the show room and found a good friend of my wifes' family worked there. She quickly became one of my favorite people, she would sell my wife jigs at a lower rate for xmas gifts for me. They downsized and the jigs they make now, I either have or I have no interest in. Plus, she moved on to another job...but the point is, I grew to really like jigs that are "store-bought". So this one is an MCLS for the table saw. It was ridiculously expensive, so it was my last one I ever bought/asked for. It is very nice, but I feel guilty when using it, so I'm back to making my own jigs again! But I still let someone on youtube engineer them.
Splining really dresses up a normal project, IMHO, and you have done well with yours....one last question...did you let the cherry sit in the sun to darken before construction? I recently purchased about a 100 bd ft of cherry from an older friend at a good price, but it was rough and after planing and drum sanding it is devoid of color.
