Upgrade for spoil board?

Discussion

I’m about to use some of these for a project and wondered if they may be useful for the clamp holes on the spoil board as can’t be pushed through…

Yes M6. They say 13mm, I have one in a caliper and it’s reading 12.63mm

I have spares so shall I bring some in and you can see what you think?

If you don’t need the we can use to replace those that slip out,

Thanks

good idea - shall I leave 20 somewhere around the big cnc?

There is a small box under the monitor, you can leave them there or in the cnctechs cabinet under the mini cnc in arch 1

I am trying to find some data on max hold strength in MDF. Obviously 13mm is a good amount of material but are we at risk of chewing up the board with overzealous clamp down tightening? Here’s a McMaster Carr equivalent but my understanding is the tensile strength is of the fastener itself. Perhaps we can test a couple to failure on a piece of scrap?

Now it’s a good time for any test as the sacrificial board need resurfacing and with members finally starting using it it will be replaced soon.
