Work Day 2nd December 2017

The axles have now been refitted to the LCP and that is where they will stay for the foreseeable future. A task delayed on Saturday as one of the mounting eye bolts required re tapping. The wheels are now clear of the ground to avoid the possibility of ‘flat spots’. The two images below show the fitted axles.

Further work commenced on the internals of the LCP and attention has turned to the inside of the main cabin door. At some time in the past masking tape had been used to fix a cover over the door vent. Trying to remove this tape also removed the paint. Not a problem as the plan is to rub down and repaint the inside of the door.

The Engagement Controller’s emergency exit  door also has the remains of masking tape; the inside of this door will also be repainted. Note, the louvre for the door vent has yet to be fitted.

The simulator was run up and remains serviceable.

Work on replacing the plywood floor continues. Hopefully this will be completed next week.


Work Day 25th November 2017

It was a case of sorting out one of the ‘I need to get around to it’ jobs on Saturday and that was fitting rubber pads to the load bearing points on the LCP axles. The axles are a BMPG modification that enable the LCP to be moved short distances without the need for a crane and a low loader! The first photo shows an axle end in position, it was taken a while ago so illustrates the condition of the LCP before refurbishment began.

Yet more of the same for a few weeks now on the T86, work continues on replacing the wooden floor under the pedestal. Hopefully next week will see the end of this job. Enough photos of this job have been provided previously.

Work Day 18th November 2017

The simulator was run up and remains serviceable. Ran for a couple of hours before shutting down.

Last week the pedestal drive chain slipped when trying to raise the pedestal so this Saturday Neil re tensioned the chain and raising and lowering the pedestal now works a treat. Raising and lowering the pedestal has to be carried out manually, a task greatly improved with the acquisition of a ½” drive ‘speed brace’ courtesy of eBay and Dave for sourcing the correct size, square, socket. Accompanying photos show the drive chain and the speed brace in action.

Pete H set to and completed the paint removal and rubbing down the aerial assembly’s Rx cover, a task started by Richard. A heat gun was used to remove the top coats which literally peeled away as shown in the accompanying photo.

With the pedestal raised once more it was back to replacing the floor in the rear of the cabin, a jigsaw of sections, hand crafted to fit. The accompanying photo shows the large centre floor section fitted. Removing the last remains of the original rotten plywood was also carried out ready for continuing the manufacturing and fitting of the new floor sections.

Launch Control Post
On the previous running of the simulator it displayed graphic controller (CHARGE) errors on the system monitor (FT81), as a consequence the simulator failed to boot. These were intermittent errors which indicated the usual problem of poor edge/back plane connections between a card connector and chassis connector(s). Saturday started with a connector clean-up which consists using isopropanol to remove any dirt and once that has dried DeOxit Gold is applied to all gold plated contacts. The cards treated this way on Saturday were the PeriBus Serial to Parallel converter, PeriBus terminator and the two installed High Speed Serial interface cards that drive the graphic controllers, all part of the Argus Analogue input/output box. Following the contact cleaning the simulator was run up without any errors, soak tested for an hour and remains serviceable.

Renewing the floor continues apace and this Saturday it was cutting out the floor sections to fit behind the transmitter, under the pedestal. The original plywood floor was bolted through metal cabin floor so before the new floor is laid these badly corroded bolts have to be cut out. Unscrewing the nuts on the underside of the floor is not possible due to corrosion (again).  The image below shows floor bolt removal, Neil gets all the best jobs!

As seen here a start was also made on removing corrosion from one of the cabin wheels.

To fit the floor in the rear section of the cabin we need to raise the pedestal a few inches, it is currently part retracted. The original three phase motor that drove the pedestal retraction mechanism cannot be used, a) we do not have a three phase supply and b) the motor is too badly corroded and is locked solid.

The pedestal gear box can be hand driven up and down, we have the right sized drive socket, courtesy of Dave S, but  in trying to raise the pedestal we experienced drive chain slippage. Looks to be a problem with not enough tension. The chain has tension adjustors so a task for next Saturday.

Work Day 4th November 2017

A team of three set-to on the LCP and T86 cabins on Saturday and more progress was made.

The simulator was also run up for some card testing and its regular serviceability check. After some initial errors from the display system (CHARGE) the simulator settled down and was serviceable. CHARGE errors look to be down to connector cleaning on card edge connectors which will be done next week. We have found that our saviour on many occasions has been Hosa CAIG DeoxIT GOLD Contact Enhancer Spray; expensive but it does get results. Note to ex T86 guys ….  edge connectors are cleaned with the correct fluids and not an eraser which I remember was common practice on the filter bank to such an extent that the gold plated connections on the PCB’s were no longer gold plated!

The four lifting eyes for the cabin have been refitted after refurbishing. The top edge of the lifting eye has had weatherproof sealant applied to prevent water ingress and hence preventing further corrosion on the inside face of the lifting eyes. See in the accompanying images. All corrosion is treated before any item is refitted.

Dave and Neil had the trickiest job as they carried on with fabricating a new plywood floor for the T86. The front section of the cabin is now complete and the rear section, under the pedestal, will be tackled next Saturday. The challenge with the flooring is removing the original, corroded, securing bolts and cutting to size to fit the wheel arches, under the console, etc. Images show the removal of the original floor, what was left of it, work in progress and the new floor in place.
