1" Thick Spoilboard

[nat_wheatley]

Any harm in using 1" ultralight MDF for a spoilboard? I typically use 18mm, but would like to go thicker, to lengthen the periods between replacement.

My vacuum consist of 4 motors mounted directly to the underside of the table.

Thanks

I use 1" no problems.

are you using it as a bleader board or spoil board ?

[nat_wheatley]

Using as spoilboard, it mounts directly to my plenum. (Not sure what a bleeder board is?)

[cabnet636]

bleeder board means you are using a vacuum and sucking air through it to hold down parts

[nat_wheatley]

I am pulling air through it for my hold down...
