Engraving with the big CNC macine

Small sign made of hardwood — using a simple 2 euro ‘V shaped’ cutter from the bargin bin at the Gamma.

The machine used for this is our large portal CNC machine. The font was simply a windows font; and I cheated a bit by first routing the outline of that font, inner and outer with a normal 3mm ball-nose endmill; and then run the v-cutter along the same path.

The letters where then painted black.

Stiff Ball Valves

We’re improving our dust-control. This sees us connecting the various machines up to a central dust and chip separator and vac-shop.

But we needed some sort of valves; so we do not waste precious flow capacity on machines that are not in use. Unfortunately the PVC ball valves we got where very stiff (especially when cold). And it would not be long before the handles would break.

We tried lubing them – to no avail.

Ultimately we broke out one of the largest tools we have at the makerspace; the abene mill.

That worked !


Vorig weekeinde was de grote opruimdag (we doen dit zo’n 2 a 3 keer per jaar – om te voorkomen dat de ruimte dichtslibt).

Met dank aan iedereen die geholpen heeft – en dankzij Fulco hebben we nu veel betere stalling van het metaal. Hier staat onze gezamelijke restvoorraad (deelnemers doneren een paar euro per kilo als ze iets gebruiken – alsmede speciaal metaal van deelnemers dat niet in hun krat of kist past).
