Workshop Dust Control Using Arduino

[Alan Douglas]

If you like technology for its own sake, that's fine.  I'd rather concentrate on the end product. Here's a shot of what gets me up in the morning, a chance to create something relatively permanent, at a local historic house:

The large stones at the bottom were already there; the rest disappeared about 1910 into the rock crusher when the road was paved.  The stone at the extreme left, I put up yesterday, about 500 lbs (tripod crane and chain hoist did the heavy lifting.  I did build the crane myself since I couldn't buy what I wanted).

Hat's off to you Alan, a nice job, I know hard stone work can be, the last big stones I shifted were when we were doing the last house up, the fireplace was built from scratch by me, I had a snatch block jammed against the right hand wall, one end rope was tied to the Landrover, the other to the lintel which was then outside, it was pulled inside through the old door opening by the said arrangement, the two upright stones were walked in, I didn't have a hoist to lift the lintel into position, anyone guess how I did it?

Lever one end at a time, with cribbing under the other?

Lever one end at a time, with cribbing under the other?

Yes Alan, that's how I did it, having built the pillars I left them for the cement to go off, the lintel was barred in front and centered, I used 4" concrete  blocks laid on the flat, one lift at a time, I used two other piles of blocks to lever from at either end, when at the right height the mortar was laid, one end was then barred over first then the other, to get it level I wedged the low end and packed more mortar in, when it had all set I pulled the wedge out...it was a bit of a balancing act...

Was that a Gate Post once upon a time Lawrence?

it was a bit of a balancing act...

Yes, it's when it becomes unbalanced that you need to be ready to run for the hills.

Not sure Alan, I can't remember if there were any holes on the faces that aren't shown, it could have been at one time but my guess is that it's last use before I got it was as an external front door lintel from an old demolished cottage, you can see a sort of darker oval area on the front (center), there are two holes, one at either end of that oval, they had red plastic rawlplugs in them, probably holding an oval plaque with a house number on it.

So it does

Nice building Alan and well done on the wall. Too hard work for me now ... in the past I would have been up for it. So today its finish the re-assembly of a Philips Monoknob chassis but not all the dial and Bowden cables. Maybe Christmas for them.

Steady on Gary, I didn't do the Wall, that came as part of the Conservatory. Just like you in days gone by I'd have been up for it with my Mate Tim, but these days I fear not. It's a pity really because in retrospect I'd have made it a bit bigger.
With luck I'll now be able to get back to more civilised pursuits, provided I don't decide to attack one of my big Tek 'scopes
