So I managed to print a second pair of pipe clamps in ABS - these ones have to be raised 60 mm on stand-offs to clear the first pipe, but the trial fit went well. Again a bit of delamination glued with acetone but should be OK. I have a third pair printing at the moment - these are in PET-G as I'm running low on ABS. But this time I've rotated the model so that it is lying on it's back, so if there is delamination the holding screws will hold it together - I should have done it this way first time ! This pair won't be done until about 11:30 tonight so unlikely that I can set another overnight run - you never know - there may be a good film on ! |

So of course I HAD to do it - I stayed up until silly O'Clock waiting for one set of clamps to finish so that I could start another set to run over night. So (I think) that's the last of the 28 mm pipe clamps made. I'd forgotten how nicely PET-G prints, but it's a b***r to get off the build plate ! I now need to make a little jig to drill holes to mount them, as these mount on the underside of the cross rail, and are in a place compromised by vari-focal glasses :clap: |

For a jig I need about six inches of suitable angle iron - casting about I found a grotty rusty bit no use for anything else, so a bit was loped off the end and sand blasted to get the majority of the horror off it, and I laid out the two holes for the pipe clamps at 48 mm centres to coincide with the centre line of the heavy box profile that I made the frame from. This allowed me quickly to drill and tap the four M8 holes for the last two pipe clamps while standing on my head under the horizontal frame bar. Once the clamps were fixed, I could finalise the pipe layout, but first I had to solvent weld the Grundfos pump feed from the tank, so that the position of it's output pipe was fixed. While the solvent weld glue was setting up I re-worked the fixings for the brackets that hold the electrical cabinet in place. I made up 1" wide strips with four studs tapped and soldered to co-respond with four of the holes (that were previously legion!) giving a much neater appearance OK solvent weld now handle able, so I could fit the pump and know where it's vertical output will be, letting me finish that run of plumbing. Nearly ready for dismantling and painting :thumbup: |

A bit more work this evening and the 'Pump House is up to roof level - or is is really a barbeque :clap: Then the frame for the manhole cover went back having mortared in the two pipes. It'll be ready for electrics as soon as the brickwork ca stand an SDS drill ! |

Looking good! Stellar job on the cooling unit! Phil |
