Default Pattern routing problems

I have recently started making Crosses for my Mom's craft business and am using the patterns she has used in the past. She always cut them by hand and sanded. Each one took a long time. I am trying to rough cut the pattern and rout the shape with a flush trim bit. I always get shattering and the wood gets slapped around a lot on the table. I even spent $40 on a spiral cutting flush trim bit to see if that would help. Any suggestions on what I am doing wrong?

Thanks

Hi Interdesk

You may want to use a template and a brass guide in your router table,or a pattern bit..
The pattern bit has the bearing on the bottom part of the shank under the cutters so it can ride on the pattern,,,the brass guide and the pattern bit will let you get on and off the template easy, to start and stop a new pass.

This is true when you are going up hill on the grain/cross the grain of the stock..(Crosses)

Your template can be 1/2" or 1/4" MDF thick stock or plastic,hardboard but not plywood..

This type of template works best in the book type/sandwich type, jig,, and a hold down clamp to hold it in place , then just do one side then flip the stock around and do the other side,,,this will give you something to hold on to..


shattering

# To cause to break or burst suddenly into pieces, as with a violent blow.

WELCOME TO THE FORUM Interdesk

If you are using a 1/2" flush trim bit with a bearing you might try going down to a 3/8" flush trim with a bearing. It takes a lesser chunk out and may be easier to control, giving a better cut.

Make a couple of patterns out of 1/2 MDF. Use a scroll saw or jigsaw. Then get a good template guide that fits your router correctly. Use a 1/4" Solid Carbide Spiral UpCut bit to cut your design from the wood you are using for your product using you new template. Be very careful, you must hold tight and start your upcut bit at a 45% angle and sink it into your product material (wood) until your router base is level on your template. Then move your router with the upcut bit in it toward your template. Make sure your template guide is tightened down well so it doesn't vibrate loose!!!
