And something else; When you put in reflex, always go more than you want. You will always lose a bit, as you noticed, out of the form. You will never keep all the reflex you put it, it will always lose a bit. One thing you will like, ipe holds shape and sets less than Osage. Osage always loses a lot of reflex, ipe will not lose near as much. You will lose some in the tillering, but not near as much as you would with Osage. If you got about 2" reflex out of the form, you will probably have at the least 1/2" when done tillering. Depending on how well you tiller. You could even keep about 1" - 1.5". If that was osage, you would be looking at about an inch or two of follow. Ipe holds its shape pretty good.
