I hope you can follow this, as it will save you a butt load of time from making another jig.

 

Use your Jasper for all the length you can get out of it.

The use a rabbit bit for the last 9/16" with a bearing guide. After that rabbit bit, use a straight cut bit to even it all out.

 

Thats a way to make even clean holes widerthan they originally were without a pilot hole available or your jig falls short.

wat size rabbiting bit should i get?

 

[dbornotdb 10+ year member]

Well you need 9/16" more. So that size rabbit bit would be ideal. But would you ever use something that size again to justify the price? Probally not.

So here is what I suggest.........

 

Get a smaller one and do multiple passes. It will mean alot if bit changing though. As you would have to rabbit it then flush cut it, rabbit it, flush cut....you get the picture.

 

As you come to the end, it is possible you may have less material to get rid of than the bit is wide. So here is where I would get a wider bearing to put on the rabbit bit to hold it back so it only cut what you need.

i heard to make a flush cutout for my 18xxx u gotta cut the circle to a diameter of 18.75". well, i just found out right now my jasper 200 goes up to 18 3/16.

should i just go ahead and cut it to 18 3/16? or what??ahhhhh i dont know what to do..

i want to use my router and not a jigsaw!!

Dante you can cut out as big as you can go and then do a rabitting bit on each side till you get the circle you want then flush it even.

/edit oops didnt read anyone elses response LOL.

Why bother with the rabet bit at all. The dimensions on the Jasper jig are based on a 1/4" router bit. If you use a bigger bit you get a bigger hole. If my math is right, a 17/32" bit would work for the exact size that you want. Use a 9/16" to give yourself a little room to get the sub in and out of the hole.

the only thing i see wrong with this maybe is that his gonna have to make the aligment hole on the jasper jig bigger. to be able to pluge the router. i know they sell other jasper jigs for bigger sizes why screw yours up. heh but those jasper jigs are pretty cheap anyways. not price but build quality stupid place where they bolt to the router is weak i have one first time i installed it, it cracked. so i havent took it off cause i dont want to break a $50 piece of plastic. they should of made the jasper jig out of metal i would rather pay 100-150 and not worry about breaking it.

the screws jasper include **** too... I snapped the head off one the first time I installed it... so the jasper is still attached as is because I got it lined up and tight w/ 2 screws for now

On the larger jig, the alignment hole is plenty big, shouldn't be an issue. I'm still trying to figure out how you broke the thing mounting it to the router...debris between the router lange and the jig? What the hell are you guys torquing screws with that you are snapping the heads off? You just need to snug them up, not crank them tight. You'll get a much better alignment with them just snug, less likely to deform the jig and les likely to break it...Don't ever plan on working at a machine shop...
