Oh Dave - my heart goes out to you. You're so close to achieving a really wonderful cut!
Let's take it from step one. B&Q (and most good DIY retailers :roll: ) sell blue decorators masking tape which is great for lubricating blades as they cut. I'd suggest you wrap your ash (or beech) in some and then fasten your pattern to the block of wood. Artists spray mount adhesive is not cheap but you use very little so it's worth buying. Spray a little on the back of your pattern, leave it for 10 seconds or so, then apply it as you did before. You should find the pattern won't move when you next start to cut.
What blades are you using? Don't worry if you have to move up to #9 so long as you're able to keep the cutting action cool. I think it's more important that you should be using a skip-tooth blade than worrying about the size of the blade. Skip-tooth blades are so very efficient at clearing swarf from the cutting edge and thereby reducing friction.
Apart from these points to watch, I reckon you've got it sussed! Try again and amaze yourself.
Reverting to the subject of MDF, this is my latest segmentation WIP:
The final piece won't look too different from this (I know, I painted some bits chrome which should be green and vice versa :roll: ), but I'm having an awful time getting a decent chrome paint finish on the cheek. Blotchiness abounds!
