  • Bell axle greasing and painting of the mechanism

    Bell axle greasing and painting of the mechanism

    Click on any picture to enlarge. Click on the picture again to minimise.

    Years ago we fully refurbished this belfry mechanism (brought it back from a non-functioning state to perfect working order). This job was just maintenance. It involved opening up the bushes (the bushes are what the axles sit into), cleaning them, greasing them with copper grease, testing the mechanism, and then a little bit of painting.

    To properly clean out bell bushes, you need to lift the bell axles out. That invariably means using lifting tackle to lift the entire mechanism just a little bit so that you get the axles up clear of the bushes.

    In the shot below you can see that the axle is up and out, and In the background you can see the lifting tackle that made the lifting possible (a chain pull)..

    Another picture showing the lifted axle.

    Note the dirty appearance around the bush. Over time grease dries out and becomes sticky dirt. It needs cleaned before new grease can be applied.

    The bush, and the axle, scraped and wire brushed to death. They are now clean enough to be greased.

    Copper grease (lots of it) in the bush – ready to drop the axle back in now.

    Axle back in place and excess grease being squashed out of the top (and the sides, which you can’t see in this picture).

    Cleaned bush on the other side of the mechanism.

    And now stuffed with copper grease.

    Bush caps cleaned and packed with grease.

    And the cap bolts greased.

    Both the caps now bolted back down.

    A short video showing bell motion testing with the caps off, and once they were bolted back on.

    Once the main task of cleaning and greasing the bushes was completed, some painting was carried out to the half bell wheel and the hanger pins area. There are three pictures of these painted areas below.

  • Cast iron hopper repair / stabilisation

    Cast iron hopper repair / stabilisation

    Click on any picture to enlarge. Click on the picture again to minimise.

    This heavy cast iron hopper was found to be badly cracked and badly secured to the wall. It sits directly over a residents front door, and had to be made secure.

    First a cardboard template was created, then taken to the blacksmith so that new round bars could be made that would fit perfectly around the hopper and secure it to the wall.

    Here you can see the new round bars fitted around the hopper and anchored to the wall using resin anchor bolts. The hopper is now very secure. The crack was also filled with a quality sealant – modern type polysulphide.

    Mesh was fitted over the hopper to prevent birds nesting within it, as had been a problem for years previously.

    Installation of a traditional stepped lead flashing. No subcontractors used or required for this work.

    Raggle joints cut out and ready for the newly formed lead.

    Lead inserted and secured with traditional lead batts (not these crappy little lead clips that are faster but less secure).

    Wetting the joints in preparation for pointing with hydraulic lime mortar.

    Joints now pointed.

    The rest of the pictures show the completed job. By this time the top strip of lead flashing was on, all lead was cleaned and treated with patination oil, and all raggles were pointed.

  • Big spires – or small

    Big spires – or small

    We work on a real variety of structures, and many of these are church spires.

    Some are pretty huge, and some are not.

    The spire shown in the first two pictures is 190 feet high.

    But it only took one 10 foot ladder to get up this one.

    It was a lime pointing job. All of the joints were fully raked out and repointed with hydraulic lime mortar.

  • Lead roof vent (lead burning & slating)

    Lead roof vent (lead burning & slating)

    Click on any picture to enlarge. Click on the picture again to minimise.

    This page shows the fabrication and installation of a lead roof vent which will, once a plumber has been to site, vent two bathrooms.

    The vent was installed on a high castle roof but no scaffold costs were incurred as we do not need scaffold for this kind of work.

    Access, leadwork and slating were all handled by BCM Steeplejacks – no subcontractors were required, which helps to keep costs down.

    This picture shows the vent on the bench during fabrication. The plastic pipe inside the outer lead pipe is there to give the plumber something to connect onto inside the attic.

    Still on the bench but nearly complete.

    We added a lead cowl to keep the rain out. The vent is now complete and ready to be installed into the roof.

    Vent in position.

    Slating around the vent.

    These two pictures show the completed job.

    Finally, here is the internal plastic pipe. This is what the plumber will connect the bathroom ventilation system onto.

  • Various Highland castle roof work

    There was a small sandstone turret to be raked out and pointed with hydraulic lime mortar. The picture below shows it fully raked out.

    This one shows it fully pointed.

    Pointing was also needed to the adjacent small set of crow steps and the mortar skew between them and the turret.

    A view up from the base of the turret.

    Looking down on the turret, crow steps, and skew.

    All of the new lime work was wrapped in hessian sheeting to protect it from the weather, and slow down the initial curing phase.

    A much larger set of crow steps that was also raked out and lime pointed. The following two pictures were taken after pointing had been completed.

    New lime protected by heavy hessian sheeting.

    In one corner of the roof a long term leak had completely rotted the sarking boards and the joist below them. These obviously had to be replaced.

    This was taken after all rotten timbers had been removed and a replacement joist had been spliced in.

    Getting the sarking boards on.

    Breathable membrane fitted.

    Slating up now.

    Corner fully repaired.

    There were a lot of large hoppers on the castle and they tended to get blocked. One was a particular problem as birds kept building a nest in it. All of the hoppers were capped with stainless steel 1 inch x 1 inch mesh to prevent these problems.

  • Code 8 lead flat roof repairs

    Code 8 lead flat roof repairs

    This was a straight forward part of a larger job. There were two defective sections of lead on the roof that were soon going to crack and allow water through. We cut out the defective areas and lead burned new lead patches on.

    Click on pictures to enlarge. Click on them again to reduce.

    The defective areas before work commenced.

    Defective lead cut out and area swept clean.

    You cannot lead burn at all until all oxidization has been scraped off the lead (both the new lead and the old).

    These last three pictures show the completed work. The area is now safe from leaks.

  • Hopper mesh

    Over the years we have had lots of clients ask us to do something to prevent rainwater goods hoppers filling up with leaves, dirt, or having birds nests built in them.

    This is the best way we have found to do it. We make up a cover consisting of heavy gauge 1 inch x 1 inch stainless steel mesh that’s secured to the hopper by the ends being folded down around the top perimeter, but can be lifted off when cleaning is required.

  • Spire general maintenance: pointing, timber louvre painting, weathervane painting. lightning conductor repairs

    Spire general maintenance: pointing, timber louvre painting, weathervane painting. lightning conductor repairs

    Click any of the pictures to enlarge. Click again to shrink.

    This work was carried out in 2018 and involved lots of general maintenance work.

    The first task was to do quite a lot of raking out, followed by hydraulic lime pointing. This was unusually difficult and time consuming due to the concave flutings that run all the way down the spire.

    cof

    All of the timber louvre windows were prepared and painted.

    The weathervane (finial) was prepared and painted with a high quality metallic based exterior paint (£70 per 1 litre at time of purchase).

    The lightning conductor had been vandalised. The local idiots had tried, and failed, to tear it off the wall to sell it for scrap. We removed the damaged section and replaced it with 25mm x 3mm copper to match the existing (over time the new copper tape will oxidize and become green like the existing tape).

    This is the damaged section. If you zoom the picture up by clicking on it, you’ll see how twisted the tape is.

    The same area once repairs had been completed.

    Click any picture to enlarge it. Click again to reverse the process.

    Most contractors use scaffold to repair / replace cast iron gutters, especially heavy Ogee gutters like these. We can do this work from rope access, without compromising the quality of the job.

    The picture below shows the suspension system used to do the job.

    First 6 foot section of gutter fitted. It’s nailed into the timber wallplate and further secured by the retaining straps

    There were two smashed sections of gutter. You can see the gap where the 2nd one needs to go.

    The bottom two courses of slates have been stripped off. You need to do this when replacing gutters. A lot of them ended up being replaced with newly purchased reclaimed slates, as the existing were soft and rotten.

    The joints are sealed in the traditional (and best) way. Boiled linseed oil putty is inserted into the joint and then compressed by the gutter joint bolt. It gives a perfect and long lasting seal.

    This shot shows the completed job. The gutters are fitted and the slates have been patched back in.

    This job also involved a lot of slate patching and gutter cleaning all around the roof. The following pictures show a little of that work in progress.

  • Hydraulic lime skews on a Highland Castle

    Hydraulic lime skews on a Highland Castle

    Click on any picture to enlarge. Click on the picture again to minimise.

    These first two shots show natural hydraulic lime mortar being applied on top of a slurry mix designed to increase and retain adhesion.

    These 2 shots show the completed skew – still moist and beginning the curing process.

    Skew now hessian covered. The curing process takes a long time. Lime reaches full strength over an extended period of time, but the first three days are the most critical and it’s during this period that we make sure the work stays protected. The point of the hessian is twofold – it’s there to: protect the mortar from the weather, and (importantly) prevent it losing moisture too quickly.

    Click on any picture to enlarge. Click on the picture again to minimise.

    Brand new hydraulic lime pointing. The spire was raked out before we pointed it (the existing cement mortar was removed).

    We also pointed the inside of the spire, as it was extremely open. The wind and rain were blowing straight through the wide open joints on the west facing elevation.

    Click on the picture to make it bigger, then count about 2 to 3 rungs up from the base of the ladder, and in that approximate area, behind the ladder, you’ll see sunlight coming through the wall at two different places. It was like this all over the place but the angle of this picture does not show all the gaps.

    This picture was taken high up inside. As you can see the daylight is shining through this open joint.

    These pictures show how it looked once it had been pointed.

  • Spire stabilisation and lime pointing

    Spire stabilisation and lime pointing

    Click on any picture to enlarge. Click on the picture again to minimise.

    This 2015 job involved stabilisation of the head of the spire followed by full rake out and repointing.

    We also carried out more minor tasks like painting the finial and fitting mesh to louvre windows to prevent birds getting in and making a mess of the inside.

    We fitted four large and strong copper cramps to stabilise the head of the spire. This was the clients favoured approach as the Church could not afford a full rebuild. This repair will keep the spire stable for a great many years to come (it will see all of us out).

    The 3 pictures below show louvre windows we recently painted.

    We used, as always, an extremely high quality and expensive timber preserving paint. We continue to specify the stuff in spite of its cost, as it lasts so long and looks so good.

    This picture was taken just after application of the 2nd coat (paint still wet).
