Packer Hill rework

After getting back from Chatham Exhibition, we took a break before erecting the scenic boards of Mauch Chunk. Once these were standing again, Gareth’s son, Celfyn (Welsh for Kelvin) found the boards were just the right height for climbing through! Steve’s daughter Anna’s dog, Bryn, is also with us for a couple of months while she moves into her first house (we hope) and he is being very laid back about all the noise I am making rebuilding Packer Hill.

The first main task was demolishing the temporary polystyrene ‘hills’ at either end in order to construct the new, larger ones. Polystyrene sheets were laid and stuck together with various glues of various efficacies! Eventually, they all dried and we were able to carve them with a mixture of a multi-tool and knives. Baseboard edges were lined with plywood.

Once this was completed, the roadway was laid in ply around the edge of the hill above the track. The base of Flagstaff mountain is being similalry rebuilt.

The other issue we wanted to resolve is the use of Big Bear with our Lenz equipment. Remember that we fudged at Chatham exhibition and used an NCE PowerCab to control the pointwork. Peter, the developer of Big Bear, has been very helpful and has now managed to recode Big Bear to work with the Lenz 23150 USB/ethernet adaptor – brilliant! This means that we have been able to lay out the control board again and it has been made to fit into a Really Useful Box for transport and operation.

Getting ready to go (to Chatham exhibition)

Over the last three weeks (while Steve was on vacation in Scotland, touring Whisky distilleries on Islay), the team: Richard in particular, but also Gavin, Steve (when he got backl), Phil, Mike, Gareth and Dave; have been getting Mauch Chunk ready to go to the Chatham exhibition.

In particular, Richard has ballasted the new track, completed 10 caboose modifications, and carved and painted the new LH extension of the river wall. Richard and Phil have done more work on locos and stock and others have smartened up bits of scenery. Steve has recorded the stock and packed it all away and modifications have been made to the Big Bear layout plan with several additional routes added.

We’re ready to go (tomorrow) for Mauch Chunk’s first exhibition in six years and the first with the Barrowmore team.

Up and Running! (or 2 steps back and 3 steps forward)

We’ve got it up and running! This wasn’t as smooth a process as we would have liked though: The first time the layout went up we discovered that the frog juicers weren’t behaving – they switched the current to the frogs but too slowly when the wheels went over and shorted. In retrospect they are designed for turnouts wired so that the switch rails moving will cause them to operate. As our switch rails are permanently aligned electrically with the adjacent track, this doesn’t happen.

Solution: Buy 39 Peco turnout accesory switches and rewire the turnouts. All peco turnouts done by Steve on Monday 8th, 7 tortoise motors also rewired by Richard on Tuesday morning. The frog juicers were abandonned under the layout for the time being. Eveything is now working.

Next problem – a MERG board overheated producing acrid smoke. Quick turn off and board replaced solved problem.

Last problem – Big Bear DCC wouldn’t talk to the Lenz system. We have temporarily resolved this by using an NCE PowerCab to control the turnouts and in the meanwhile, Pete of BigBear DCC is rewriting some of the code for usĀ  to ensure that Big Bear will work properly with Lenz – excellent support!
