Learning a new skill for someone like me (past 60, PD limited and an old fart basically) is always a challenge. However, like the time when you first hand bend a set of sides without fracturing them, I have had that moment when you mentally fist-pump the air because you have 'got it'. Turning on my $7000 CNC router is no longer an adrenalin thumping rush, but a matter of fact, "Hey, let's do some work today" experience!
So let me share a couple more projects with you:
Side port cutting jig: I had mocked one up before I got the machine and it got misplaced in the workshop. An ideal opportunity for me to develop the protoype that was 'lost'. This jig is used in conjunction with a hand held plunge router and top bearing trimmer cutter. Side ports in 2 minutes flat!
I had abandoned the electric ukulele when I sold my beloved Elu pin router. I bought the CNC to make logos (the cost over time of out-sourcing this would be the same as my investment in a machine... in theory anyway) but found I had other ideas for it! So I resurrcted the Firefly design.
I bought $1300 worth of 20 year old Korina in 7' square billets for this project and after 5 weeks have 'got it'! This electric body is entirely machined on the CNC router using a multipurpose hold-down jig that enables me to flip the body for cutting the front pockets after I have machined the back access pocket... For caution I run my machine slowly. The back access pocket takes 5 minutes including fixing and repositioning of the blank on the spoil board jig. At last, a neat and appropriately shaped access port.
The front pockets and profile take 42 minutes and I have a few refinements to make but overall, I am pleased with this result.
I have to mind the machine when doing the backs but while the fronts are under way, I can be doing other things like shaping the neck which is done using jigs on a router table and a dead-head sander.
I also have revisited my passion for making small boxes.
but as this is a luthiers' forum I'd better find a project appropriate group to show these in eh?
What I have learned - I am truly a kinaesthetic learner. I learn best when I am showed how to do something and interpret the world through pictures. I cannot calculate or process written instructions and as long as I know where the emergency stop is and can figure out what 'up' and 'down; really mean, I am OK
