Shaun.

It just depends of how intricate a pattern you are cutting too, I assume that it won’t be too intricate considering you are going to use 18mm mdf, so I would use a No 7 or 9 reverse tooth, this will help prevent breakout on the lower side of your work piece.

Hope this is of help.

You can’t have cut much mdf then, think before you post.

Take care.

Fuzzout would be a more accurate term for mdf breakout.

Hmmm ?
I guess it depends on the individuals definition of 'break out'.
For me, break out in scroll saw terms, means some kind of damage caused by the blade to the bottom of whatever is being cut.
Break out occurs most in grained woods where the grain can be kicked down by the teeth of the blade, thus causing unwanted damage beyond the edge of the cut.
Using reverse tooth blades goes a long way to help prevent this.
Break out on MDF can't be compared to break out on grained wood as there is no real noticable damage beyond the edge because of the fine particles the board is made from.
MDF does however, give a fuzzout (as Col names it), which is more annoying than damaging.

Just my take on it.
