the constructional hearth is not the finished visible surface.

Are the flow and return from the boiler the right way round at the valve?

I've never seen a trench block...

Yep i got a set of forks for our 2.7t machine. Darned handy but awkward to use, and on a smaller machine the weight of the forks does eat into the lifting capacity a bit. / the brickies thought it was great for getting the blocks up a lift of scaff...

self-tapping and self-drilling are two different things...

what about cold rolled steel sections rather than timber?

shame you weren't close enough to this family member to have helped her earlier?

I've a set of 1m SDS+ bits that work well, even in the DeWalt cordless SDS

I'd say you'd need a good 7-10cfm for either of those and if you're considering spraying remember that there might be an air-fed mask in the equation. If you're short on space this is a good option: https://www.sgs-engineering.com/stanley-fatmax-b350-10-90v as that's the same motor and pump the "normal" belt drive machines use

All piston compressors are noisy. Box it or outdoor enclosure is all you can do for that... The oilfree vertical you've got aint 10cfm, maybe calculated but no way in the real world. The piston leaks like a sieve on them. Plus IIRC that model is a brush motor and revs it's n*ts off. ^ that one in the piccy above is the same unit that Lidl sell occasionally and is a real sweetie for the money, the pump is overbuilt compared to SIPs and Sealeys of the same class required cfm depends on the type of tool, and whether the demand is continuous or intermittent. Eg for a rattle gun, hose size is more important than pump capacity- it needs a good jag of air to break a bolt loose which even a small tank will contain, but if there's a bottleneck at a hose or fitting well... Tell us what tools they are and how you use them

any chance there's a simple NRV under the allen screw that incoming charge pressure bypasses?

how many pipes go to the buffer/ is there an additional pump associated with it?

leave it all to go stone cold. Start it up and monitor the hot pipe. If it immediately heats but then cools back to warm, then that's low gas for sure.

they do a single valve at 137€ too, but that's not dear really
