Swaggasaur Posted February 23, 2011 Report Share Posted February 23, 2011 i have a craftsman router, nothing fancy. i need to make rings around the subs for a fiberglass project, but they have so many different ones, i dont know which one to use. also, is the perfect circle from mobile solutions the only good circle jig out there, i know of the jasper one, but i heard those break easy thanks BHE Wall Build TEAM DC Audio TEAM XS POWER1986 Monte Carlo KMC Nova's 20"4 DC XL's W/ PSI Recones2 DC 5k'sPioneer PRS 8010 Audio Technix 6 XS Power D3100's 1 XS Power D3400 Mechman 220a Alternator Link to comment Share on other sites More sharing options...
baaudio Posted February 23, 2011 Report Share Posted February 23, 2011 i made my own circle jig out of 1/4" mdf i had laying around. cheap and easy. just make sure you have some scrap mdf to test your holes with. id recommend a 1/2" upspiral cut bit, 1/4" will work too but is more likely to flex under load.

Hey do you wax your circle jig before using it? I have always done this with home made jigs but wanted others opinions on this. And to the op, it's easy to make your own just make sure your measurements are accurate.

Swaggasaur Posted February 23, 2011 Author Report Share Posted February 23, 2011 Is it like using a compass for math? And can I find this bit at lowes or do I have to order it BHE Wall Build TEAM DC Audio TEAM XS POWER1986 Monte Carlo KMC Nova's 20"4 DC XL's W/ PSI Recones2 DC 5k'sPioneer PRS 8010 Audio Technix 6 XS Power D3100's 1 XS Power D3400 Mechman 220a Alternator Link to comment Share on other sites More sharing options...
Rell Posted February 23, 2011 Report Share Posted February 23, 2011 (edited) Yeah you can get it at lowes, homedepot, sears etc. If you decide to make your own circle jig then you can use a 1/2in bit. But if you get the jasper then you have to use the 1/4in bit. Make sure you get a 1in x 1/4 or 1in x 1/2 so you can cut all the way through 1in or 3/4in MDF. I was using a bit like this, but it was 1in x 1/4in. They broke on me two times. And yes I was going slow and cutting in the correct direction. http://www.lowes.com/pd_31056-353-85279MC_0__?productId=1082821&Ntt=router+bit&pl=1¤tURL=%2Fpl__0__s%3FNtt%3Drouter%2Bbit%26page%3D2 Then I bought one like this, so far so good. http://www.lowes.com/pd_57163-353-85911MC_0__?productId=1093177&Ntt=bosch+router+bit&pl=1¤tURL=%2Fpl__0__s%3FNtt%3Dbosch%2Brouter%2Bbit Edited February 23, 2011 by Rell Link to comment Share on other sites More sharing options...
slim2fattycake Posted February 23, 2011 Report Share Posted February 23, 2011 spiral upcut is a great bit. And the jasper jig is nice too. I like it. I don't understand why people break them so easily. I tend to take care of my things. It hasn't showed a sign of wear yet. but you can make your own. I had to make my own for a 2nd baffle flush mount on an 18" sub.
