Guys

Making a dolls house for the girls xmas. Putting about 10 windows in
it..so made up a nice template from a 9mm offcut of mdf - basically 8
windows about 1 inch square in a row of 4 x 2.

Bought a template bit ( with a bearing at the top of the cutter) and
off I went with my router. I am cutting through 9mm mdf with the bit...

First window went fine..Then noticed as I cut more that the bearing
appeared to be reshaping the mdf template...Suffice to say, after 1
usage some of the template was wonky and cutting curvy window shapes...

Essentially the bearing was routing the edge of the template...I
presume this is the soft MDF..any clues as to what wood to use to avoid
this...Would ply work before I buy a bloody big sheet..

MDF is soft but you must be pressing really hard to notice a problem
after such little usage. You could try plastic electrical tape f it's a
one off or recut the edges and put some formica or something equally
hard in as a lining. A strip of tin or some such or even lollypop or
chopsticks. Whatever is hard and handy will fit the bill.

You might be able to drill out most of the orifices with an auger bit
to ease the load. I don't know if if that helps?
