I bought a router (black and decker) so that i can cut circles. Turns out that I suck at cutting circles with this thing and now I find out that i need a perfect circle jig. AHHH! Ok no big deal. So I am looking researching on these perfect circle jigs and the one that I get the most results about (Japer Perfect Circle Jig doesn't even fit my router without modification. Anyone have any solutions?

 

One word....ROTOZIP !!!! has an attachmentfor circles. I use it for all the boxes I build.

 

OOOPs! Sorry, I don't quite have that problem. Luckily, I work in a woodshop factory where I work on a CNC router machine. I can rout any possible shape, including very precise circles. But, if I were you, you can also use a jigsaw if you make a good template. Take your time, and it will come out right.

 

I saw that in Lowes the other day it is basicly a compass that uses a rotozip instead of a pencil right?

 

Fiddlesticks, now i have to buy another power tool. How much is this rotozip. This sounds like a balck and decker product. Thanks fellas.

 

Unless you plan on doing this professionaly I would not go that far.
And I am sure that it would work with any rotory tool like a dremmel or whatever

 

I tried using the router and i suck at making circles. i also boought the black and decker rotary tool (RTX) and suck using that. I guess I will get better in time but do you think that a rotary tool can cut through 3/4 in of MDF wood. I am worried that i will break the bit that came with it. Thanks.

 

You can buy side cutting bits at almost any home improvement store $5 for 8. The key to using a RTX and a side cutting bit is clamping the wood down like a **** and using both hands on the RTX

 

Ahhhh interesting. Thanks for the advice Patrick.

 

For those wondering about the rotozip....Yes it will cut through 3/4 MDF with no problem (bit it came with). That is all I use for my enclosures (or ultralight). Second..If the enclosure is already together you do not need to clamp anything. Third..The Rotozip is an all around handy tool to have ! Theres many attachments for it to do virtually anything. I sound like a damn spokesman for the thing. And yes it probably is the thing that you saw at Lowes. It is NOT a Black&Decker product it is Rotozip. That is the company.Check it out....http://www.rotozip.com

 

I know what a rotozip is I was talking about the atachment

 

O ...then yes the attachment is what you described.

 

no robozip, dremel, those of us computer mod'ers know what im talking about
i was going to say just use a compass draw a circle and cut.

I did that. well with a template, but what i meant was cutting the circle with a router doesn't come out perfect, at least not with me.

 

You could always cut it small and sand/grind it out perfect

 

The thing I was doing wrong was cutting along the line, when i should have been a little outside leaving room for sanding. Oh well at least I am learning. Thanks to all who responded. One more thing, anyone heard of perfect circle jig, anyone know if where I can get it besides the internet? I tried looking for it at Home Depot but no luck.

 

In this order:
Drill
Jig Saw
Spindle Sander

The roto-zip is no where close to as powerful as they imply. It has trouble even with 3/4 inch MDF. It can burn through, but it takes a while.

 

Works fine for all my boxes !

 

Spindle sander? What is that used for? i never heard of a spindle sander and I am wondering if this can't be bought at a local home improvent store. How much do they usually go for? i will look this up. Thanks for the info.

 

I think I have seen them as cheap as a couple hundred. But a good quality model that will hold a large sanding wheel will be more expensive. It's the type of thing that you find out where is, and then make sure you have a friend that can get you access to it. Because most people will almost never use it in a home shop. A home shop substitute would be a sanding wheel for a drill press.
