I was asked to remove a small safe from an office that was bolted down to a concrete floor with thrubolts. There was nothing in it but they had lost the key. A 3ft crowbar had that straight out the floor, no bother.
People miss this tiny filter in the block (I cant remember its name) that is generally at the end of the hose from the bottle. It stops all the crap from the bottle reaching the main filter. Should be checked at every main service.
Lovely work and I'm interested to see it working!!
I hope you run a blade guard on the overhand planer in the background. I have the scars on two fingertips from using a planer without the guard. I was extremely lucky just to take the skin off.
