Better day today. Got 14 of the 16 inner baffles cut, inner and outer.
I finally figured out how to get an accurate cut on the inner circle. I was getting variances up to a 3/8" and I couldn't figure out why.
I found this series of YouTube vids and from there it all fell into place.
This is part two, but the entire series is good for cutting exact measurements. He doesn't come out and say it, but if you watch his steps he lays the entire cut out before he makes one cut. And this guy is talking about cuts to the 32nd.
In other words all his measurements are made from the get go.
I was measuring my outer circle, which by the way always came out 'tits', and then measuring my inner circle. Even though the center point did not change, for some reason the inner circle cut would always vary. Once I started laying out all my cuts before I made the first one I got accurate and consistent results.
That and get rid of the freaking tape measure. Use a steel ruler. I started using a framing edge and my precision doubled.
Another tip I got from the YouTube video that was good, but I don't know if it helped, was to measure out your inner and outer lines and mark them on your board. Then put the router in the jig on the board and lower it so you can slide it to the point where the wide part of the bit hits your measure marks.
I was putting the jig on and measuring from the bit back to the center pin.
Hope this helps someone. Everyone has their methods that work, but for those like me who have no methods it's good info!
Anyways....... just like yesterday my day ended with another broken bit. I was in the home stretch cutting the second to the last inner baffle and half way through the first cut it just snapped. This time it was my fault though. I got greedy and tried to split the cuts into two cuts not three.
I'll get a new one tomorrow and finish up the inner baffles.
I might start on the outer baffles but I want to see what edge profile I want to go with which might determine that I go with a larger outer baffle than originally though. I got a half to 3/4 of a day before the rain hits. Then I'm out a dead stop on cuts for the foreseeable future. Oregon...
Once ski season hits I'm gone with projects.... God I hope I don't have to go without base all winter.
