Restoration diary

Dave spend the day cleaning the brake chain & mechanism in the no 1 cab of Renown, Ian, Pete & Chris B removed the 12 remaining fuel pumps to be sent for overhaul & I tidied some more completed cable runs in the cubicle of Repulse, started to bend the fixing bolts for the board mentioned last time & examined the three boards with the wheelslip relays & their resistors. There are three wheelslip relays & three resistors on each board & one board is required per loco. One board seems to have been removed from a 50 rather roughly, as the one corner is broken off where the one fixing hole was, so that one is not usable. The other two boards are intact but someone had tried to remove the resistors before we acquired the boards, and sheared off their fixing bolts level with the boards in the process. Many of the cable fixing bolts for the relays are similarly sheared and can be replaced with brass ones, but the resistor bolts will need further investigation, so I brought one board home to see if I can devise a way to re-secure them.

Dave, Ian & Pete torqued the remaining 10 cylinder heads down to 600 ft lbs, a somewhat lengthy task, having to remove and replace two of the large head fixing studs which had damaged threads. Dave had spent the weekend on site again & during Saturday had fitted new flooring in the no2 cab of Repulse. Chris B unbolted three fuel pumps. Tim & Dom had a good tidy up around our locos and coach, and removed old cab flooring round to the bonfire site, and I fitted and wired the battery charge diode, tidied up some sections of cabling with cable ties & Chris B helped me thread a long section of 16mm cable into the cubicle which connects one of the circuit breakers to terminal bar 7. With that last section of cabling fitted, all the fuses and mcb's are fully wired, and the small relay board that goes in front of them can now be fitted.

Tim & Dom did housekeeping duties around our vehicles, then started hoovering accumulated debris from under the cab floors of Renown & the rad compartment passageways. Ian & Pete fitted the last three big end bearing caps into the power unit. Dave started to free off the siezed handbrake mechanism in the no1 cab of Renown and cleaned & painted more cab parts. Now Steve & Sarah have recovered from their car crash enough to be more active, they visited site & I discussed various options with Steve for replacing severed cables inside Renown. They then removed some of the flooring alongside the elec cubicle and by the brake frame & started removing accumulated debris from under the floors. We had a quick look to see if any of the severed cables could be matched with their 'other' ends, and we think we may have identified those to the DSD relays. I test fitted a small relay board inside the electrical cubicle of Repulse, but the fixing bolts need bending a little to bring them back into alignment with the board's mounting holes. I also fitted the Battery Charge Diode. Kev Hand made a surprise visit & returned both reversers he was storing for us, as we are now in a position to permanently fit the proper one into Repulse.

Dave Rolfe continued measuring, cutting and fitting flooring into the no.1 cab of Renown. Chris Bodell painted some more cab fittings & panels, and varnished the completed flooring in no.2 cab, Ian & Pete fitted two big end bearing caps now the suppliers have sent Ian the nuts for the stretch bolts that they were out of stock of. They were in the process of fitting a third cap but one of the four stretch bolts seemed unwilling to fit, so they had to remove the cap to see what the problem was. Nothing was obviously amiss, but by then the light was fading, so they didn't refit the third cap. My two GWR mates (Matt & Roger) who had visited a few weeks ago again came up, this time armed with some 185mm through-crimps and a large hydraulic crimper, so in the morning we did a test joint to see how it looked, and the result was encouraging. After crimping both sides of the crimp, a layer of heat-shrink sleeving was applied and heat-shrunk. A large amount of insulation tape was then wrapped round the crimp over the sleeving, then a second layer of heat-shrink sleeving was applied and shrunk. We used the group's 1000v Megger to check if there was any leakage to earth, and the Megger result was a full-scale needle deflection to the Megger's capacity of 2 Mega Ohms (2 million ohms). Any reading over 1 megaohm is considered good, and as the Megger only registers up to 2 Meg, the actual reading would therefore have been higher, which means this type of crimp, which is rated at 11,000 volts, should be more than adequate for both the severed main traction cabling and the main ETH cabling, as the maximum expected traction voltage is around 1000 volts. If I can find someone with a higher-capacity Megger, I will repeat the insulation test. Joining the cables in this way will remove a significant amount of time, effort and expense from the work needed to complete Repulse. After lunch, we crimped the last couple of 16mm cables, connected them, then Matt connected four cables to resistors on top of the cubicle which I am too much of a shortarse to reach.

Dave started fitting new flooring in the no.2 cab of Renown, Tom continued work in the no 1 cab of Repulse, Chris T & Tim continued loading items into BG2 and rebuilding the horn air feeds in 30 with parts taken from the cab of 50037, Chris B spent the day painting power unit coolant and oil pipes, Ian & Pete refitted the last cylinder head and began fitting some of the water piping, Dom lifted the remains of the rotten flooring in the no.1 cab of Renown & cleaned out the accumulated debris underneath & Mark brought some recently acquired spares to site & undid the remains of one set of the severed generator cable conduits in the clean air compartment. Two ex-GWR colleagues of mine visited today, partly for a look at progress on 30, partly to advise me on possible ways to join the severed motor cables under the cubicle floor without having to rewire with expensive new cables, and partly to lend me their hydraulic crimper to put new lugs on a few more 16mm cables.
