Howdy All I am Darius, I work with jjwallace. Any ways I am working on the first car from the Bone Yard Racing team. The first will be a hearse for the door-slammer race at Black Top Raceway in July. I have the chassis and have been working on some modifications. First I put in a mean green arm (measured about 6.1 Ohm) With the Mean Green the over all drive train resistance was 62 Ohm (shoe to shoe with both brushes engaged) After adding Braids, braided shunts and Thunder Brushes the total drive train resistance dropped to 48 Ohms. I haven't run it down a track yet but I like the base results. The paint job will either be Jack-o-Lantern the and called "Hell-O-Ween" or safety yellow and magenta tri-foils and called "Decay Heat". Haven't decided which yet but I am sure both will eventually be used. here is the over all shunts and braids  shunt 1 by Don and Monica Riney, on Flickr Braids and Shunts just after soldering  shunt 2 by Don and Monica Riney, on Flickr Shunt solder joints filed for clearance  shunt 3 by Don and Monica Riney, on Flickr |

I might be wrong but I think the doorslammer class you cant run briads and stunts. But Im posting this from my phone so its harder to find the rules lol.

As long as I am reading the right rules (beeing a newby I might not be) they are allowed www.nitroslots.com/thread/2293 but if not I can use this chassis later I have 2 more 4 gear's that should get here Monday. |

You can run them. I found the rules under the 2013 race schedule thread.

Cool. Not sure if the braid shunts have any real advantage over wire shunts but I thought I'd try it all the same. Shunt systems for industrial and process systems typically use a woven braid, so I figure they must know something.

Hello darius, braids and shunts in this class are allowed, looks good. For info on classes look at where it says Most Recent Post look to right of page and click Directory next to NTRA all rules can be found there. Good luck with your car, see ya at the starting line.

Looking good Darius. Like the approach. I look forward to seeing the rest of the build! Hell-O-Ween gets my vote.

Never thought of using braided wire. Excellent idea.

Well the lodge and Chapter captured a bit of my time the last couple of months but I haven't been sitting on my thumbs. the hearse body I got from Eagle Racing (thanks for hooking up a rookie Eagle) has been modified a bit to fit on my experimental chassis  Hell-o-ween by Don and Monica Riney, on Flickr My braid shunts may have to go as mounting the body gave clearance issues. More on that experiment as it develops. However the Halloween theme marches on!!  Hell-o-ween by Don and Monica Riney, on Flickr still looks a bit rough but I always liked the new teams trying to break into the top classes. Darius |

Just in case any one wondered the experiment in using braid for shunts was a complete failure. Not only where there some body clearance issues but the braid ended up scaring the com when it got tucked in the body. the scared com is on the left in this slightly blurry pic. I am now using 30 guage wire wrap wire to make my shunts.  SLOT CAR BUILD by Don and Monica Riney, on Flickr |

Hey Darius,
Just caught your thread. I've been using braided silver wire (from Lucky Bobs), Wizzard product, if I remember right. Sucks up solder fast so you have to be carefull not to use to much solder so you keep as much flex in wire as possible.

Been hard at work here at the bone yard. Been building the Olde Oaks Proving Grounds. Named it after the cemetery that appears in my front yard every October. Hopefully having a test track I will be able to improve on my times and rely less on JJwallace to help me test and tune. If every rookie had tech help like he gave me it would become a very hard racing world! the Track is an AW scale 1000 set that has been retrofit to a Slot Dragon timing system. the retro fit wasn't bad as the gantries came off of the AW track pretty easy. little hot glue work to mount the sensors  20131228_141533 by Don and Monica Riney, on Flickr I used 3/4 in long 1/4 in head wood screws countersunk flush to the track to mount it to the boards had to extend the wires for my finish line and pull them up next to the track. I use one unmounted piece of track to connect the two half's and I can hang it up on hooks in the garage when not in use.  20131229_122511 by Don and Monica Riney, on Flickr I made some test passes with my N F/C's and every thing is working now to get working on my FED build! |

Excellent Don....looking very good!!  You will find that having a test track......any test track is a huge advantage. My first test track was 10ft long Tyco track with a wall wart and a homemade digital stopwatch timing system. VERY primitive, but the 1st race I entered after setting it up, I was in the finals (Dragfools 2012 King of the Streets). Also....you give me too much credit. Your builds have been pretty solid. Just some fine tuning needed. Good luck with that fever you're fixin' catch...lol!!

well the FED is built, going out to the proving grounds in a bit to see if it survives.  FED by Don and Monica Riney, on Flickr AW 4 gear with a 3 ohm arm, poly mags that have moved up to reduce the air gap. Braids Shunts and Thunder brushes. I might play with the gearing before the Feb race but I am short on time for this one. |
