DIY Vacuum Fixtures

[Boyan Silyavski]

I made some test jig from wood. Works perfectly.

One thing is clear to me now. All hosing from compressor up to the CNC must be industrial 1/4 or 3/8, cause i will step on it, solder over it and so on. It must be strong so no cheap PVC hoses here. Added bonus is that i use the same hoses and extensions like for air. So the only thing i bought is the 3/8 quick connector which i fitted at the compressor inlet side.


Decided to save on connectors :-) so i drilled the vacuum fixture and just pushed the PVC hose inside, it works perfectly. Recessed all the necessary areas 3mm. Drilled hole to the back so the vacuum fixture is self fixing to the table. Hole could be closed and instead fixture clamped.

The mat is non slip mat from chinese shop -2euro. 15mm wide rings, i wanted a superb friction.

Next step will be when i have time to fit the Vacuum switch to the compressor, check the negative pressure achieved and test if using vacuum reservoir/the compressor tank/ is better in any way.
