Western Chip

Big diesel loads of room, pick-up from one side of trailing bogie and one side of power bogie. First off cut power bogie wire and some extra wire.

Attach chip with sticky pad to centre weight.

 Connect the chip cable to the prepared loco cables check on program track to read loco ID=3 if so shrink the insulation over soldered joints test run and set the CV’s

Q1 hamfisted attempt to remove the capacitor

A nice easy one this Hornby Q1 DCC ready
or not my Q1 looks as if it was chipped then de-chipped before it went on eBay!



Looks like a real hamfisted attempt to remove the capacitor


I have had enough of wiring today tomorrow is another day.


Even the DC blanking plug was not in correctly testing time I think..

Home made OO gauge rolling road update.

I eventually received my order from Hatton’s today 6 chips and a replacement lead for my prodigy unit
I thought I would order Hatton’s new small 2 function chip and 5 standard ones. As you can see the small (red) chip is badged DCC Concepts. I guess they are all from the DCC Concepts range.

Yep all my range of locos fit the rolling road.

Home made OO gauge rolling road.

The bearing blocks are made from ½” square aluminium and ½” aluminium angle 17mm long held together with 2mm S/S cap head screws.



Holes are drilled and reamed to accommodate the 3/16” S/S rod which forms the guide rails.



Cross drilled and tapped 3mm for the locking screws. NB I inserted a small length 2mm of 2mm diameter plastic rod into the locking screw to protect the guide rails from bruising.



The support blocks are drilled to accommodate the 3/16” S/S rod and finally the holes are marked and drilled for the bearings using the guide rod as a datum. My bearings are 8mm Diameter x 7mm wide salvage from dead laptop hard disk drives. I think an MR83zz bearing would do the trick Outer Diameter 8mm Bore Diameter 3mm Width 3mm.


A quick check to see if my diminutive Pug will fit! 



As all was well I mounted the support blocks on to a 5mm thick piece of clear acrylic 330x 65mm with 3mm countersunk screws.


I sprayed the underside of the clear acrylic base red to make it more visible. 


In order to support longer locomotives a length of Peco rail was screwed to a piece of black Nylon shimmed to bring the height to that of the rollers.



 Electrical connections are fixed on the support blocks and bonded to the Peco rail with 20 gauge tinned wire. The final picture shows my Q1 sitting on the road.

As this project requires a metalworking workshop I have just skimmed over the details. I will leave it up to you to fill in the blanks.
