Ya I know, been asked before no doubt....
I'm a hobbyist woodworker, will never go pro. I make furniture and cabinets, mostly. For self and friends. I often incorporate dovetails into the project. I just like how they look I suppose.... No other reason. My drawers tend to be half blind, and I try to cut through DT's on other projects. I've tried to cut them by hand and I simply do not have the time or the skill, and have no interest in mastering that skill, at least not now.
I bought a PC Omni 24" many years ago, maybe 20. I have all the templates too, including the adj through DT template. It's a beast and well made, but jeezus, it's a friggin PITA to set up and use. And as infrequently as I use it, I have to re-learn how to use it every time. And the mess..... It's horribly messy. That takes the fun out of this 'hobby' for me.
When Leigh entered the market, I can recall many wood workers talking about how easy it is to use, and many Omni users moved to the Leigh.
I also have an Incra router table system, and have used it for DT's too, but it sucks for cutting long'ish boards.
The question I'm pondering now has to do with ease of use. I'm considering buying a Leigh 12" Super jig for the bulk of stuff I make with through dovetails, or I might just get the 24" Pro model, but if the Leigh is every bit the PITA to set up and use that my Omni is, then I have just wasted money to use somewhere else..... I know that Leigh has a really good dust collection attachment, and that might just be enough to convince me to buy one.....
I'm hoping someone with experience using both jigs might offer an honest opinion and talk me into, or conversely, out of - buying one of these Leigh Jigs.
