I purchased a Laguna/Robland NLX-31 combo machine last year and need the long slot mortising bits for the horizontal mortising feature. I have had a hell of a time finding these. Perhaps I am not looking in the right place. Laguna has been no help over the past 9 months (surprise!). I do know that the bits need to be left hand rotation, and have a fairly long cutting depth (maybe 2 to 3"). Do any of you have any experience with this attachment and/or the bits for this or any similar machine (i.e. the Felder or MiniMax, etc.)?

Any help would be appreciated....thanks.
