    Karrier WDS

    When I was an undergraduate in the 1980's many students would go inter-railing during the long summer holidays. I did not. Instead I worked at the Elmswell Bacon Factory. Pigs came in at one end (around 3,600 per week) and everything you can make out of a pig came out the other end. They say you can use every part of a pig except its squeal; the maintenance staff found a use for it: the noise that came from the steering of the pallet trucks... but the place was awash with brine, so everything rusted. Eric King would come on shift at 6am, muttering to himself "f* job, f* job, f* hat
  2. Try E Dobson &Co., Keighley. They made the copper non-asbestos gaskets for my Karrier (and numerous other projects). Just send them an old gasket to copy (in a self-sealing polythene bag) or knock out a paper template. Quick turnaround and very reasonable on price (or at least I thought so). Doc.
  3. Evenin' all. Sorry no post last week. Was busy with other things... So we had our week in the sunshine at Dorset; rain too but we stayed dry under the temporary roof. At least it didn't snow, unlike here. Yes, it snowed in our little corner of Suffolk this Easter Monday morning. So having returned from Dorset, with "I'm envious of your body" still ringing in his ears, David proceeded to remove the near side top panel for repair. The following photographs chronicle the process. This is the bottom rail, feeling a little fragile and sorry for itself. The top rail

    Another week in the workshop fiddling with my small parts. It's lockdown who can blame me? I'm tempted to ask "Can you tell what it is yet?" In reality, "they" would be more appropriate. Hose barb fittings for the gas pipe to the headlights. Here's the pipe clipped to the front of the bulkhead. Most photos show the acetylene generator on the front of the step. The governor linkage and choke rod are now fitted. I've also made one of these... the missing knob from one of the crankcase doors. and fin
  5. Was flicking through some odd copies of Motor Traction and stumbled across this: Doc.
  6. I have a theory, born out of experience that if you look forward to something too much, it inevitably disappoints. So if you were expecting another carpentry instalment... sorry. No crane either. But some heavy lifting. It's now 4th August 2018. Careful measuring had determined that the roof trusses were tall enough for the workshop body to pass comfortably underneath. More careful measurement revealed that the doorway was lower than the roof trusses and it was not going to come out of the shed where we had built it. Well, not on the railway sleepers we had used as a base. So we had to ja
  7. Correct: tongue uppermost, no tongue on top board, no groove on bottom board. No secrecy so far as nails are concerned. Subterfuge, maybe. Nails and screws were all sunk below the surface of the boards and hidden with linseed putty. Elsewhere (e.g. floorboards, front wall boards) screws were used. So we sourced genuine slotted screws as per the original construction, not one of which will ever be seen! We rightly consider the carpentry craftsmanship, but it was simply how things were done. Ian, our builder friend, was able to read the remains of the original joints and know exa
  8. Hi. Good question. The tongue and groove is nailed to the frame. Nails at the ends of the boards are driven in at an angle. When I post pictures of the repair of the near-side top panel, this detail may be more visible. While we're on details, there's a thin wooden strip on the top edge of the rear bottom panel. This was fixed with alternate screws and panel pins, just like the originals on the corresponding side panels. Doc.

    2018 Great Dorset Steam Fair my brother was greeted by a fellow WW1 exhibitor (who will remain anonymous) hollering across the showground "I'm envious of your body!" I'm not sure why this should come to mind as I prepare to share photographs of my small parts... So I've been making parts for the Yorkshire-built lorry on my Yorkshire-built lathe: knob for the choke rod and collars for the governor control rod Back collar in position with a small tap wrench clamped up snugly behind then transferred to the milling machine to drill the split pin hole T
  10. Who knew that "beer shaming" was a thing. It's a bit earlier in the day and as I'm sat here contemplating this weeks update, I'm finishing a cup of tea. Comments, criticisms... Anyhow. I start on 23rd June 2018, GDSF is looming ever closer and there's still loads to do. Woodwork was generally an evening job after Ian had spent all day on the refurbishment of the house; generally speaking, he would set up the morticer and David would chase in the mortices, meanwhile Ian would be cutting the tenons. Between them they would complete the necessary parts. This first section concerns the u
  11. It's that time again... Are you sitting comfortably, then I will begin. It's now early May, 2018 and time for a trial fitting of the back board and it's new hinges. First the backboard was clamped into place then the hinges fitted on their long pin and clamped up against the backboard, before the holes were drilled through for 1/2" Whitworth coach bolts to secure the hinges in place. One fixing in each hinge forms the pivot for the legs; this is screwed into a nut, rebated into the back board, and the thread peened over to prevent the nut from coming off. Rebates were also cut for tw
  12. Hi. I looked back over the post and realised that this is turning into one of those authentication tests "tick every box with a wheel in it" The wheel in the background of the picture titled "old and new" is IHC 12-25 Mogul. But in the second of this week's pictures there is a Saunderson on the left. This is a work in progress and the project that was paused when the Leyland came along. Doc
  13. It's now 22nd April or at least it was when this next back of pictures was taken, detailing the trial fitting of the bow ends. This really felt like progress as they gave a tangible impression of the finished form. The majority of the iron brackets are originals. Note: the top fastenings form part of the hinges but as a temporary measure 5/8" bolts were used. The lower ends were secured with square head 3/8" coach screws. David scoured our favourite on-line auction site to find enough to complete the job. After this trial fitting, the frame was dismantled and off to the

    Karrier WDS

    Karrier progress has been slow of late. On account of my extended period away from work I've not had access to the machine shop. The last few weeks have been spent commissioning my own workshop. First machine to see action is my Dean Smith and Grace lathe. This would have been scarcely five years old when the Karrier was recovered in 1977; it's still got plenty of years left in it. A very different machine to the Harrison M300 I'm used to, it has to be said. I repurposed an old copper drift, turning it into a mandrel to support the broken steering ball joint so it could be welded ba

    Sorry I've not posted anything here for a while. I made a little internet purchase about a month ago but have been waiting for it to arrive... surface mail from Australia. So here it is: Aerial view of the Karrier works, c. 1930 according to the vendor's description. Enjoy. Doc.
  16. This weeks instalment starts on 1st April 2018. Pinch, punch, first of the month and no returns. Now that's out of the way... At the same time as we were rebuilding the workshop body, the house was also undergoing a thorough going-over. Our builder, Ian, has a fully equipped carpentry shop and after a full day at the house would think nothing of giving up his evening to oversee the complicated joinery required for a faithful recreation of the workshop body. The corner posts are tenoned into the frame; these joints are reinforced with iron straps. We re-fitted the bottom side panels
  17. It's that time again. This week's update is from 30th March 2018. The workshop body had been built up to floor level on the Leyland chassis but the shed in which it was being built was not tall enough to accommodate the full height of the vehicle so we had a bit of a move around. First the Leyland was towed out of the shed and steered into position under the crane - that object of envy. Next the body was lifted up into the gods and spun through 90 degrees (so the iron brackets would clear the beam of the crane) allowing the Leyland to be towed out and shunted out of the way. Afterwards a
  18. The originals were tongue and groove; we've replaced like for like. Doc.
  19. There's snow on the ground this first weekend in February. This week in 2018 saw the floor starting to come together. The bearers had taken their turn in the paint shop and were soon reunited with the chassis. Meanwhile, replica angle iron brackets had been made based on the Duxford examples. The tenons and mortices had been cut in the sill beams, marking the start of the structure of the body. These were trial fitted on the bearers then the bolt holes drilled in-situ and rebated out to receive these rather curious square headed bolts. A full set of 10 bolts had be
  20. Part Three. January 2018. (34 weeks to go before Great Dorset Steam Fair). The cross bearers were a bit rotten on top and to a greater or lesser extent on their ends but are big heavy timbers 8" x 2 ¾" so the decision was taken to repair rather than replace. There's a theme that permeates this little corner of cyberspace "old = good, new = bad" This does not apply to circular saw blades; modern blades will cut through anything! So the rusty remains of nails and screws posed no problem. New pieces of ash were glued and screwed to the top faces. The front b

    Yes, that looks like the same building, though the terrace of houses has been lost, along with the factory building in the near distance. As soon as Boris says it's ok, I think I need to take a train ride to Huddersfield and do some exploring. All very interesting...

    If the building could be protected I would say "Not before time." We've lost too much evidence of our engineering prowess as a nation already. So where is this building in relation to this one: (can no longer remember the origins of this photograph - I likely found it on Google - reproduced for research/educational purposes) I thought I had seen a picture of the stones from the Karrier Motors frieze on the ground. Is this a different building? Does it still stand? Please excuse my ignorance. Thanks Andy
  23. The last instalment of this tale left the workshop body reduced to floor level, surrounded by a plethora of decaying timbers. Today I'll describe the start of the reconstruction. We have tried to salvage as much of the original timber as possible. As built, the workshop body sat on two steel plate reinforced longitudinal timbers, 2½" x 6" x 12' 4" long. After a lot of ringing around we managed to find a sawmill that could supply these and our other requirements in English ash as originally used. The first job was to make these fit onto the chassis, boring clearance holes at regular intervals
  24. Glad you're enjoying the post. I'll have my curator's hat on again later this evening, sorting through the next batch of photographs to accompany a 2nd instalment.
