Mostly doing research on power solutions and waiting on materials needed for the track elevations and banking. Not sure if you’ve noticed lately but FedEx and UPS really suck when you compare them to Amazon and USPS.
I try not to buy CCP products as much as possible but sadly there are simply too many things that are simply not made anywhere else these
days. That’s another subject entirely of course. But even products that are already in the States seem to take forever when shipped by the major players. And, no, it’s not related to the “supply-chain” hoax. In fact, these days you can expect at least three days where the item(s) just sit in some shipping hub location for a long, long time.
Anyway, waiting on spacers (standoffs), wire, wire sheathing, power components, and other items right now. The track is pretty much secure to the table just need to set the banking and overpass elevations but need the proper spacers and screws to do that. These pictures show the proposed overpass height and shape. I think it’ll be challenging for both L4 magnet cars and our other less stuck platforms.
The banking elevations and shapes will be different on each of the four corners. I’ll decide on that once I get the needed materials and start to shape the oval corners. The banking will likely be less than SR2’s banks but fairly close at the highest points. Of course, I’ll do my best to make each corner as different and challenging as possible.
Once I get this stage completed, it’ll be time to secure each track piece completely to the table and then start the basic track and power tap wiring. I’m planning a “Phase 1” power solution for the track opening, which will be at least the same power control setup we have on the SR2 VSR track. Phase 2 will be driver-selectable voltage levels for each lane, from 3v to ~28v, which will also be programmable from the track computer by the race director.
Two purposes for these features: one is so that we can test/practice different types of cars in the same practice/test session and not have to switch voltage levels; the second purpose is so the race director can reset each lane’s voltage to the proper levels prior to each race.
Don’t forget to register for Round 2 of the Formula “E” Series this coming Saturday, January 15, 2022!
Also, if you know somebody who you think would enjoy racing little cars with us, please invite them along. We always need new drivers to join the group and it’ll benefit all of us when we have a large enough “club” to always have more than enough racers to support our events.
Remember: SR3 is six-lanes! That means we’ll need at least eight (8) participants to have any hope of full utility of the track and enough turn marshals. Yea, we can run just four lanes, but that’s not cool!
Okay, shut up and drive!
With plenty of other tasks to do the rains have been keeping me indoors. When that happens, I usually play with slot car stuff or hack on computer stuff. This week has been all SR3 construction.
In the case of a convertible oval-to-road course track, you have to get the oval layout dialed first. Then you have a fixed starting point for the rest of the puzzle. I didn’t get the oval to align together perfectly but it was extremely close and I didn’t have time to start over and get it perfect. These shots show the track in various stages of placement completion and the complete placement of the entire course.
Excavation and geology work has been difficult with all the much needed rain. But construction is progressing and we’re on schedule!
The base table is almost complete now as you can see. I just need to finish fastening the table top sheets to the frame, cut and route the side and end panels, then paint and assemble. After that, it’s all about laying out the track, oval first, and securing anchor points to keep it in position as the wiring and electronics are installed.
Lots of decisions to be made so I’m anxious to get some veteran racers over to comment on things. A couple key decision needed are what side of the garage the main start/finish straight will be on, what pit spacing to try first, and what layout to employ for the grand opening race day.
All construction materials arrived today, December 20, 2021. But not without drama, of course. I won’t bore you with the details but I did have some issues with the lumber supplier.
In any case, all the lumber products
I’m also considering flush-mount driver’s stations instead of the horizontal platforms that SR2 has. I really like the platform-style stations but SR3 is over a foot wider as it is. Adding the platforms would make it almost 8-feet wide! So, bring your Fray pit-box hanger and deal with it! Sides will be 3/4 MDF. More construction reports to come as construction proceeds. Oh, and I’ll have Bowman or Viper controller holsters, haven’t decided on that yet.
