    OK Folks, re my trailer/tower I now have at least part of next weekend free, so will try and get the tower collected this week.  Just need to swap over tow ball for NATO hitch on my car, should be OK.  Assuming I manage this, anyone able to help out reassembling the tower?  Sunday the more likely day for this, although I’ll keep a close eye on the WX during the week and if Saturday is better, will try and swap.  I still have the original wires so unless anyone thinks its essential to replace them, we can just use them and replace sometime in the new-year.

    John,

    I am not available as teaching on Saturday and going to visit my mum & dad on Sunday (haven’t seen them for 3 weeks due to work and other commitments)

    Sure someone will help you but apologises that I can’t.

    let me know if its on to collect on the weekend, and I’ll get it brought out from “buried” behind piles of steel etc where it has ended up. Its in the same corner where you dropped it off that time. I’m away the weekend, so will advise others here that you’re coming (if you are). Otherwise you might get booted out as a probable tink!

    Geoff, will come through Friday evening then. Missus using car in afternoon but will make sure I get it back in plenty time for 6pm curfew.

    Cambell/Bob P looks like Saturday then.  Assuming we manage to get it back to working order on the day, can it be put back in storage?  Not v popular at bringing it back to driveway for the fortnight until CQWW SSB.

    Tower now back at my QTH, what a transformation, thanks very much, Geoff.  It’s been some slog especially paint stripping the tower sections but this has made it all worthwhile.  I’ve got a bit of one section still to be done.  B&Q first thing for more NitroMors and I’ll try and get as much of this done as possible before reassembly.

    Update: Thanks to Bob IKT/Cambell DXC who visited to help put the tower back together today.  Just needs a few tweaks but is already usable for CQWW.  Looking great, and will have the final touches done in the Spring-time.

    After a 7 month gap over the Winter, the CCC Tower was brought out to work on the next task – add in a metal frame to build a small shack. Geoff MM5AHO (and son Matt) had arranged to come through to work on this yesterday (Sat 25th) and Colin GM0RLZ also visited, complete with Mig welder.

    As you can see in the photos, the first major obstacle was that the brake hangs down form the lattice section, and sits within the area we were looking to use for shack space. As it couldnt go any higher up the tower (it was only 1 rung from the top) Geoff suggested relocating it to another side of the lattice, and Matt got to work fabricating a new bar with lugs to pivot the brake on.

    Meanwhile Geoff removed the far end support which holds the lattice section when in the lowered position. Although this 2-part support had always been ceased together, Geoff, when galvanising the tower, had managed to separate the 2 sections (I was unaware of this) and a quick strike or two with the hammer and they were again separated. We then put the lower section back on the tower, and inserted the upper section at a slightly higher height which again bought us extra headroom for the shack. The lattice section, whilst in its lowered position, now sits horizontal, just like the versatowers, whereas before it was pointing downwards at the front. Another repair was carried out at this stage. The plate at the bottom of the support was mis-shapen, causing the support to sit off-centre. A few hammer hits soon solved this.

    Next up was another problem that the lattice sections sat slightly off-centre in the far end support. To fix this, we loosened off the tower base plate, plus the 4 diagonal struts that give it extra support. Whilst Matt moved the lattice sections into a more central position, Geoff and myself quickly fastened the base plate and 4 struts back down. Tower now sits nice and central.

    Next up was the shack frame and with Colin now also on site, he was able to cut and form one side of the frame, whilst Geoff was already putting the other onto the tower chassis. This all came together nice and neat in no time at all and with the bonus of having some extra angle steel left over, it was decided to add in a door frame as well.

    Later in the evening, I sanded down the new angle steel and coated with Galvafroid. One coat left to do, and then I need to start adding in the plywood walls/floor/roof.

    This has been a really satisfying project to do (even if I took a big backseat at not being able to weld) and if the end result is a towable tower & shack in one, that keeps some us of doing contests over the Summer season, then it will have been worth all the effort. I still need to look at the raising wiring of the lattice sections and I now also have a wheel bearing problem on one side, but that can wait for another day. Links to some photos of the days work are listed below as I’m unsure if pics can be attached.

    John, if you use the “IMG” link from photobucket, the image will display in this forum (without using up this forum’s storage capacity). I think you used the link that transfers the browser to photobucket.

    Be a good idea to get some paint on the welds of the re-located brake too (but you probably remembered that?).

    I’ve now extended the time a post can be edited to make it easier to correct problems and I’ve put the photos back on John’s original post.

    To embed photobucket images into a post, just paste the ‘direct’ link into the post and the image will be embedded automatically
