Hmmm ... leather.
Here is how I profiled mine. I think you can take a bit more MDF off.I'm not entirely satisfied with the top baffles and may have been a little conservative with the amount of MDF I removed. I'll revisit these at the weekend before I glue them to the cabs.
If sanding indoors take a look at this:-

Excellent piece of kit, highly recommended.
They make a larger one as well.
'scuse for butting in, but I've taken to using Decoflex and ironing it on using aliphatic glue (Titebond III).
Easy to do and works a treat for me... here are some little uFonkens I made last Christmas http://www.audio-talk.co.uk/phpBB3/viewtopic.php?f=4&t=5997&start=60#p130592...

So here's something that's bugging me, I have some ideas about the lipping of the front of the side panels but on re-reading Gareth's most excellent thread on his build I came across this and for the life of me I don't know how he got from (the second picture in the post with the lipping glued on) this to the super sharp scarf joint. Gareth, how did you do it please? My only thought was to fix a straight edge in line with the angled part pf the side extending over the lipping and use a bearing guided router bit to trim.
My lack of skills may already be starting to be exposed....
