"Nib" removal on MDF cutouts edges

[JAZZCNC]

However I do not think that PODZ is the answer as I imagine that with profiled alphabet letters nos. etc. it would be very difficult to be able to cut right through without damaging the pod as the items are likely to be quite small.

Yes agree Geoffrey that's why I said if largish shapes. I built a machine for someone who uses it for letters etc and they use DST but it is a pain to them and a vacuum bed to hold small parts is out the question due to size of setup required as you know.
Tabs are good but again cleanup required so time.!!. . . . . It's a challenge but if was so easy everyone would be at it, which they are starting to be.!. . . Lol

Looking at both bought and home made, I wonder how accurate they are. For example you have a piece of aluminium, say 300mm square, it's even thickness all round, you mount it on the pod, then do an engraving cut at 0.2mm all over the surface, will it work ?

In this case eddy you have them pull down to the POD surface (It's a differant setup to what I posted but same setup as I described with cutting groves and using gasket) and the gasket just forms the seal. The trend setup and the PODZ style of pulling to sealing tape is only any good for wood use really where that level of accurecy isn't required.
