Re: Adding alcohol to graphite

Adding alcohol to graphite doesn't seem like a worthy road to pursue. That said, there may be some potential for using an alcohol/tungsten-disulphide (WS2) mixture for coating the bores and hub surfaces prior to a graphite lube. https://www.lowerfriction.com/howto.php The key would be applying the p...

Re: DFW wheel angle and edge

Vit K, have U been able to test run the different angles of dfw degree on your car? If so, how much of a difference has it made in your times? Just curious as I have much to learn. Thank U . I haven't really. I have theories on why a lot of bend is better than a little, but I haven't been able to d...

Re: DFW wheel angle and edge

I usually run about 7-9 degrees on the DFW.

What I've heard the league racers say is akin to "As much bend as you can put on the front axle and still be able to get the wheel on."

Re: Need replacement switch for RaceMaster timer

We have a four lane Grand Prix track with a RaceMaster timer, but our starter switcher thingy (sorry for the technical lingo) is not working. The small piece of metal that triggers the timer when the cars are sent down the track does not start the timer. Any suggestions for a replacement part? Any ...

Re: Practice Track Plans

I gotta say, if you're gonna invest all that time and energy into making even a simple track, why not spend a few bucks for an actual car kit, with real wheels? I think the metal washers might eventually damage a wooden track.

I'm hoping to finally build a practice track this summer, but I thought I'd crib off of these plans here:

Re: BSA axle ridges

AaronS, I think I am starting to gravitate more to that way of thinking regarding BSA axles. I used to carefully file the ridges down, but now I just remove the flashing and polish the crimp marks smooth. Some folks on the league forums who race in the "Box Stock" division have suggested this is pre...

Re: Lanes width for none center guided tracks?

The Super Track site says each lane is 3.4 inches wide.

Re: Derby Magic Test Track

Have you had any issues with track straightness? I have heard some folks complain of a lack of rigidity from the plastic, so the track tends to meander.

Correct, my first idea is to get some thin ply wood and use if that can be attacked to the frame.
Along all 32 feet???

That sounds like quite the project.

Honestly, just build a tuning board and go with that.

Re: Testing your car on a guided track,when racing on a lane track

Ok. My NDFW is raised. I did get the single 32 foot track from derby magic. I will post something about it. It should be at my house when I get home. Storage and price is why I went with it. The timer and program is a steal when it comes included. ( Wish I would have found this group befire a bough...

Here is a pic of how the wheels of my car are set up.

That pic shows positive camber on the DFW. If you're running a sidewalls track, I think you'd be better off with negative.

Re: Testing your car on a guided track,when racing on a lane track

Thank you for the advice. You have way more experience than I do on this. I'm going to say some things about what I have read. By no means take this as challenging your experience. I'll tell you what I've read and you can tell me if that is right or wrong. Again, please don't take this as me saying...

Re: Testing your car on a guided track,when racing on a lane track

Take this with a grain of salt, as I've never built a side-guided car. However, here's what I'd attempt to do if my kids' race was on side-guided track: - Set the car up to "rail-ride" on the sidewall. To do this, I'd do the following things: -- Raise one wheel in front -- On the non-raised front wh...
