New spoilboard preparation question8/6
I'm curious as to how much material people are removing when the pre-surface a new spoilboard on both sides.
Are you removing .015" per face, .03" per face etc.?
No need to get into a discussion on edge sealing, vacuum power, machine type etc. This is just a question of spoilboard surface removal amounts for different types of MDF.
No defined amount for me.I just skim until the surface has all been machined and no low spots are left.0.5mm below the point of first contact is a good start.
same as John here. I skim it until it's entirely flat, then flip and repeat.
I am generally removing .3 mm with a 4 inch diameter 3 flute solid body Vortex 8040 cutter. It is a really beautifully made tool.
I take off .04" each face of a new spoilboard. That seems like just enough to get to the nice porous stuff for our mdf.
I start at about .005 and see where I am then adjust from there
Waste board thickness consistency varies for sure. I start at .010 and see what that gets me, then go .005 until flat, flip and take off another .010, usually end up taking around .040 total to get a flat waste board. I use a spoil board that never gets touched and a waste board that gets used up and pitched at about .075
This so more about removing the mill glaze from the MDF. That waxy glaze that needs to be removed from both side to ensure best possible air flow.
.015 per side
I read on a forum of a guy using a 1/4 inch spoil board with out ever surfacing it. I tried it and it works awesome.
If you dont surface the spoil board how do you know your deck is flat? Even 1/4" material could vary substantially in its thickness.
