Davey goes a'routin' ....
thought I better get my own thread for this stuff. Progress so far.. started with this on a 9mm 1200 x 900mm board 
It's got one railed lane, works very well. Locking wire is a combo of 80lb fishing line (0.9mm dia.) topped with regular red light duty hook up wire from DSE. Railing thses tracks is time consuming, but the finished result is worth it. This test track is very tight, yet I can hold my SG+ flat out on 20V except for the inner hairpin, only the slightest backing off required. The paint is a hi gloss enamel, after undercoating/sealing with an oil based primer. Both coats were sprayed on, no problems with paint in the slots  Silicone tyres stick like glue on the surface, rubber tyres are a different story with a bit less traction. Maybe a semi gloss is the better option, might try that next.

Moving up a notch, I'm now attempting this on a 2400 x 1200mm board  |

Re: Davey goes a'routin' ....
finally got it all done. 
Using the edge routed method means it doesn't matter too much if things are out by a few mm, although I got it pretty close
Next is the cutting out.. |

Hi Dave, Looks good! Did you get the test track finished? What does the fishing wire do? Boost the height of the locking wire to the top of the route? Cheers Richard _________________  |

Re: Davey goes a'routin' ....
The test track is going to stay as a single lane for now, mainly a proof of concept type thing. Might finish it off in the future tho. You got it right about the fishing line, I was very pleased to discover the line has its diameter given on the spool, and at under $5 for 150m the price is excellent  I guessed at the 0.9mm line, and it was spot on.
Cam, can you get me small spools of light duty hook up wire for cheapies?? Failing that, it's only 25c per metre at DSE.. I plan to have the 2nd track finished in a few weeks, it's still a bit small compared to our plastic tracks, and should be faster too. A double board sized track is what we'll need eventually. PS after marking the whole thing out, all my arc centres are already marked, so I've actually gone back to swinging my corners with a radius arm lol only prob is, some of the curves are too tight to swing on the inner lane, so will have to figure that out another way.. |

Re: Davey goes a'routin' ....
How is your rail spacing? Sounds like I need some fishing line

Re: Davey goes a'routin' ....
K-Mart - 80lb fishing line, 0.9mm 150m $4.64 there is a 100 lb, 1.0mm variety for the same price, but it's "only" 100m Rail spacing is good, I get about 15.5mm outer to outer on the straight. It varies a little on the corners, but every car I've tried so far works well. I did put the locking wire outside the inner rail on the centre hairpin, but prob wasn't necessary. |

Re: Davey goes a'routin' ....
I've been busy with this project, just don't remind me of the other things I should be doing 
began with cutting the pin slots  |

Re: Davey goes a'routin' ....
then cut the rail pockets. Getting the depth right for these is tricky, not as easy as "set and forget"  had to go over some bits twice, I can put some of it down to board flex, but the rest is a mystery..

Re: Davey goes a'routin' ....
gave it a quick undercoat, will give this a light sand, then recheck the rail pocket depths before I apply the top coat. Still undecided on how to finish this track off, I'm tempted to cut some bits out cos it will look better. I may even route a "gutter" around the track edge so it's more clearly defined. Needs something done as the paint hides the actual track border..  |

Re: Davey goes a'routin' ....
maybe just paint the track surface rather than the other bits ? if you're using a spray can it will give some interesting results.. i wouldnt bother masking just try and keep it all together and see how it goes, might get some might faded spots ? |

Re: Davey goes a'routin' ....
Dave, I found my router was moving up and down slightly; if you were routing a large piece (a coffee table, for example), a 0.5mm variance isn't a big deal, but because we are routing tiny sections, it's a big deal. I found the same as you, routing over again cleared up the problems. But it's looking good!!! Cheers Richard _________________  |

Re: Davey goes a'routin' ....
yeah I thought about masking stuff off but I think I'll paint some grass islands on the inner bits, along with ripple strips etc No spraycans used, just my little compressor and spraygun

Re: Davey goes a'routin' .... time for an update
couple of top coats applied, I got my original grey paint tinted much darker, looks alot better
so here we have one freshly railed routed 4 lane HO track. Test laps show up how tight the layout is, but it's still fun. Still to come are the table frame, power wiring and reed switch install. After that it I'll dress it up a bit with ripple strips and green infields etc  |
