Cutting circles with the Cavex jigsaw and circle cutter attachment

[Greymule]

I am new to the board and a new Festool owner. I purchased a Carvex PS 420 and the circle cutter attachment. I want to cut some circles out of plywood. My question is: How do I start the cut in the center of the plywood without drilling a starter hole for the blade? Seems simple if I start on an edge for an arch etc. Are there any videos of the such for doing this? Thanks!

I'm guessing you want the circle piece in the center and don't want it to have the starter hole for the blade. If that is the case you could do a plunge cut with the jigsaw. Just turn off the pendulum then make a plunge cut. Start up the jigsaw then on the front of the base rock the jigsaw blade down and in. I'll try to find a vid

That is exactly what I want to do. I knew there must be some way of doing this besides setting my radius to start on the edge of the plywood. Thanks for the help and a video would be great if one exist.

Here's a Trion making a plunge cut:

Thanks for the video's, not sure how accurate I could do this. maybe I should use a router. Thanks again for the help.

Hey,

I have tried using the circle cutter attachment thingy for three times on three different occassions, but what a terrible piece of equipment I must say.
For me it is impossible to work with, and I have watched video over video to find the problem.
I have checked the blade grip setting, I know where to punt the little pin in the circulair adapter, I know where to attached the jigsaw.

I actually have two circulair adapters (there were two in the accessoires box, by accident I guess) but both have the same problem.
The blade keeps running out of "track" so to speak, then heats up, sparks will come of, eventually brakes, runs out the circle track and destroying the wood piece in the process.
Any other ideas?

Luckely, for now the only Festool piece that's #$@#

Are you using the smaller blade that lets you cut tighter curves?

In the past I would double stick a thin (1/2") block in the center, drill a hole in it only, set my radii, drill a starter hole on the outside of said radii & cut out the circle. Now with the way the Carvex's circle cutting jig is made it seems that it would work much easier due to it flexibilty , no more dinking around to get a square cut.

Yep agreed, thats how I do it leaves a complete circle piece without any centre hole. (once you remove the block).
