I do it after. It's a lot more stable of a work environment then.

Routers will funk you up.

I sliced my thumb open just putting a straight edge bit in my router. //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

I can't imagine what kind of damage a router can do if it was to get away from you at full speed.

X a billion on the after //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

With my jasper the pin is so tight it doesn't usually fall. Instead I have to be careful not to let it kick the bit into the baffle . I go real slow once I get towards the end . Then stop the router the second the circle is finished , and don't move the routr at all until the blade stops spinning. Then pull out the disc , and use the router to trim the little knib that's left sometimes . //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I usually do it before. I have a few pieces of sacrificial wood around and a big roll of double sided tape. Tape the baffle to the sacrificial piece drill into both for the pivot pin and then clamp the whole thing to something that isn't going anywhere. I use the saw table. End result it that the center piece is supported when you've cut all the way through and it doesn't spin. No danger of cutting into the baffle and no little nub left either.

Another thing I've found is that a striaght cut bit is the worst POS ever for use with a circle jig. I tried one for one cut instead of the spiral up-cut bit that I normally use because the spiral bit I had at the time had been dulled from use. The noise from the straight cut bit was deafening (and yes it was a brand new carbide bit) and the quality of the cut was not what I was used to. I promptly took the straight cut bit out of the router, threw it in a drawer and went to HD to get another spiral bit. The spiral bit clears the chips/dust out of the cut as you go and doesn't take as big a bite out of the wood making for less strain on the bit and a cleaner cut. Cutting 3/4" MDF or plywood in a single pass is a simple affair. Cutting rings and recesses with only an 1/8" thickness is simple. Bottom line is that I'll never go back to a straight cut bit.

cool thanks for the info too bad i bought a streight bit last night at HD cause the retards that work there could not help me lol

new problem though.

i have a double baffle. i want to counter sink my subs. so how would i go about making the larger circle since the center will be cut away. or do i do the larger one first and only go .75 in down...?

Router down the larger circle first, then the cut out the inside/smaller circle....

With a double baffle, you usually want to make the cutouts singly. Line them up and clamp them to drill the pivot holes and then cut the two holes independently. Glue the two parts together afterward.
