Years ago I bought an Akeda Dovetail Jig and have been happy with it over the years. It worked well, was easy to set up, etc., plus it was typically OK with dust collection hooked up to my large Festool dust collector. Well, it has become just too difficult for me to get replacement bits, collars, etc. and from what I have observed the Leigh dust collection system works well. As a result, I ordered the Leigh Super 18 with the accessory dust stuff. I figure I will have to learn to use it, but I was wondering - are there any tips for me to consider from those who use the Leigh jigs? (One thing I figured out is the 24” one sags just a tiny bit in the middle - hence the 18. ( Also I never could get my Leigh Mortise/Tenoning jig to work with precision, so I still use my hollow chisel mortiser and cut tenons on my router table or my table saw, which probably delayed my decision to buy the Leigh jig.) Another thought - does the Leigh worth using to make sliding dovetails?
