I guess you've tried the usual Iso Propyl Alcohol or white spirit?
Not yet, that is my next option, along with some other more agressive liquid cleaners
If that fails, then its on with the Dremel, but that will very lightly damage the surface

I would recommend finding something non abrasive if you can as using a grinder will just give somewhere for more dirt to accumulate.

I have used this technique before, and very little fine dust is expelled
The surface only needs to be cleaned, not trimmed down
If that doesn't work then there is no point using sanding tool

I spent one hour this morning running my most reliable Class 47 up and down the layout, inspecting one point at a time

Three points, no problems
Three points were found to be faulty

Closer inspection confirmed it was the same part of the point
Lined up with a metal ruler and the point is correctly aligned
Wired up an auxiliary cable and the model runs over the point without any problem

Closer inspection and it would appear contact MUST be made with the switch blade
A minor adjustment and the model runs over the points without any problem

Progressed through every point and managed to get my Class 47 over every combination possible
Swapped to other models and they too managed to complete the two main crossings, which wasn't possible before

Sadly my Mercig Studios Class 47/7 derails on one point, so will come back to that one later

Sadly my Mercig Studios Class 47/7 derails on one point, so will come back to that one later
So after a break decided to try and work out why this model only derails at one location
Close inspection of the point showed the centre was raised slightly
So back in the pliers and bend the outer ends
Several runs and no problem
Just to check ran several other models over the same section and no problem

That just leaves the outer point to have one soldering joint inserted

Started construction of the final baseboard, that joins the fiddle yard to the two scenic baseboards
I wasn't looking forward to this as this baseboard needs to be cut to size, from a 4'x2' section to 0.95mx2'
The cut edge looks to be straight, but will only know once the edges are aligned and screwed

Typical, my last Dremel cutting disc has shattered and brought progress to a halt

From memory the box had 20 such discs and I have slowly been going through them, with 5 slightly thicker discs
I know I had one left, so kept it solely for where precision rail cutting was required
Yesterday was filing down the ends of tracks, but I have 8 cuts left to make
Swapped over to the last disc and it shattered just as I was nearing the end of the first cut

I am struggling to find the thinner discs, plenty of the thicker ones
I have ordered a pack, so need to see what arrives middle of the week

Those abrasive discs that come with the kits don't last long at all.

Although I haven't had the chance to use them yet (still laying the trackbed!) I purchased some of these http://www.ebay.com.au/itm/151593827410?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

With any luck they might last a bit longer.

DC or DCC, that is the question.

The discs on eBay UK are 0.65mm and that is about double the thickness of what I require
I have ordered one set, but the thickness isn't published
In the event they are thicker than I will simple move the track to reduce the gap

Todays progress was a little hampered by the inability to cut the track
So the wiring on this final baseboard was completed
This included the wiring harness that joins the DCC system

This also allowed me time to order the SPROG 3 and look at replacement laptops, as I will need one for the upgrade to the DCC system

Replacement Dremel cutting discs arrived this morning, so all I have to do is locate the final baseboard, cut and trim the track

SPROG 3 also arrived, discussed here :

Will look lovely after a good wash.   :laugh:

Very nice though.  Mercig?  I should have another one from Ian in just over a week.

Yes, all my locomotives are now being replaced, all completed by Wickness Sounds and Mercig Studios

Ian (Mercig Studios) completes locos in batches, hence why all five Class 47 were completed at the same time, but this Class 37 is 6 weeks later
If you submitted a Class 37 then it should be nearly complete

My next batch are also Class 37, as I have enough Class 47 at the moment
These should be completed by the end of the year

The next batch after that are Class with the majority of the Class 47/7
This includes 47702 as I want to see what the flush end conversion looks like
These should be completed by March 2016

A further batch of Class 47 will follow that, including the last of the Class 47/7 (all require flush end conversion)
These should be completed by July 2016
