Re: Referb of an old gate

It does sound like it's not getting enough current but 10a should be more than enough looking at the spec sheet. If you power it and slowly raise the gate by hand, does it ever snatch it open or does it only hold it once you get it open? I see the solenoid has a plastic guide for the plunger, might ...

Re: Are we due for new wheels?

Don't think "Unlimited acrylic razors", think "BSA wheel but without the wide tread". Mold some fluting on the inside face so you could tell if it's been thinned, leave the current markings on the outside face, maybe have the very outside edge as a raised band to keep the wheel off the tread bumps b...

Re: Are we due for new wheels?

If they're getting ready to update the molds, I would love for the wheels to come with some kind of witness marks inside of the wheel to help dissuade people from doing internal weight removal. As long as it's some sort of marking that can't be duplicated with machining, I think that would be a gre...

Re: Oil -Freezing

I would use oil, never had a problem with it freezing in the winter or getting baked out in the summer months. It'll be A-OK fine!

Re: Cub scouts/Girl Scouts

I would say to let her race in whatever groups she is a member. If the cub scouts race the girl scouts it sounds like she has the chance to race herself then? She'd need to build a new car though, right? Our rules require that a car can't have run in competition before, do you have a similar rule?

Re: Red Rocket ?

I don't think they call it Liquid Glass any more? http://www.mptindustries.com/mpt_products/classic.htm or http://www.mptindustries.com/mpt_products/argos.htm Paul, it takes very little wax to do a set of wheels, a small bottle of Red Rocket would likely be enough for your whole troop.

Re: Best Track Mods

If you can keep from removing the gate and switch from the track and do a good job leveling during set up, I think you'll see consistent times from venue to venue. I recommend removing the start switch any time the track is removed. Just mark the switch position under the track, so it can be reinst...

Re: Best Track Mods

It makes the track noticeably sturdier when you're wiping it down, but I can't say it made the track any more consistent. Even if the track sections have a little sag on the long spans, it doesn't change from run to run so the times shouldn't really change either. I did use aluminum angle stock for ...

Re: Aerodynamics ?

Yes sir, I directed our pack to the video during our PWD informational meeting back in December. I thought he did a pretty good job of explaining the basics where a young person could understand. I also advised them to watch out for other videos on youtube that appear to be "how to's" but they are a...

Re: Fastest Pinewood Derby Car Designs and Pinewood Derby Rules

I can’t believe they’re still touting a quick start front as being a speed secret these days! I thought those went out of style when the spring loaded start gates came on the scene?

Re: Aerodynamics ?

I think that the BSA doesn’t do enough to emphasize the STEM aspects of the PWD. They are focused on model building and sportsmanship. Not unimportant goals, but it seems they could do more with it? Not to derail the thread but if anyone has seen a curriculum that includes STEM concepts on PWD topic...
