Re: Mass-Producing Lead Weights for Scout Use?

Darin, if it's just for display purposes, why not use a gray two part epoxy in the canopy mold? You could either mold in a mounting stud or insert a dowel before it hardens?

You do know that a brand new one is $39.95 (plus shipping), right?

Re: Ideas towards Cub-centric wheel improvement...

Hay Vitamin K, Can't blame you for wanting to go whole hog for the Grizzly lathe. I'd like to have one to tinker with myself, ;) Don't think any one would blame you for staying in the the range you were looking to spend for a lathe as well... so I'll toss this link your way. http://www.ebay.com/itm...

Re: Mass-Producing Lead Weights for Scout Use?

You could just have your scout use a hacksaw and clean it up with a file?

Re: Mass-Producing Lead Weights for Scout Use?

If parents want to avoid lead, what about square steel rod? As an example: http://www.homedepot.com/p/Everbilt-1-4-in-x-36-in-Plain-Steel-Cold-Rolled-Square-Rod-801197/204273977 Cut into 1.5" lengths it would fit into the same space as 6 of the 1/4" tungsten cubes.

Re: Providing Better Kits for Scouts?

The standard BSA car kit with a set of Maximum Velocity #4094 axles would be a nice kit but the axles cost as much as the car.

Playing the devil's advocate here - you know that including better quality axles in the kit means less work that the scout gets to do on the car, right? :D

Re: Making Wheels Round

Pin seems fairly well polished, but you do bring up a valid point. Unfortunately, I don't own any pin gages, so I can't do a before/after check. I do intend to do bore prep /after/ shaving the wheels down for outside trueness, though. Speaking of bore prep, I've always wondered how much the bore ge...

Re: Freedom Track Mods

That looks like a good candidate for an electric release. I'd mount it perpendicular to the deck and keep the existing handle just to make it easy. I think that with the solenoid attached to the track it would minimize any shake.

Have you considered adding weight plates to the rear uprights also?

Re: Freedom Track Mods

I would like to see a new design to the start gate. Have a trip handle that you pull back or push forward. I've been trying to think of a way to do that without redesigning the whole start gate. I'm not familiar with how the Freedom track gate operates. From the picture, it looks like the handle is...

Re: "Float" test -- Thoughts please!

If you have a smooth tuning board with a foam bumper at the end, you can let the car roll down the board from a fixed starting point and record the distance it rebounds. The farther it bounces back, the faster it was going. Don't even need a rail.

Re: Best Track Mods

The track our district uses for all the packs doesn't have a foam bumper for the start gate. Here is a video of how the NPWDRL start gate swings. I believe this has the Owens mod but before the bracket racer mod. I don't know what else was done to get it to swing down fast and not bang into the und...

Re: A nose-cone for a tube of pennies?

Thanks for the suggestions, folks. I like the idea of the party hat tips, since that's easy enough to lay hold of. Will have to try some of the other possibilities as well! Still think drilling 3/8" holes and getting the lead free pwd weights at the hobby store is pretty easy. Not arguing that, but...

Re: Setting up my Test Track

How would I change the angle of the slope? If you have levelers on your track you can adjust the angle easily with those, if you don't, then you can adjust the angle by sliding the leg hinges slightly higher or lower on the hill. And there is no such thing as being "too obsessed with pinewood Derby...

Re: Anyone manufacturing Wood Tracks for sale?

PBT, I built the wooden track from these plans; http://www.pinewoodpro.com/images/GP%20 ... 0Plans.pdf
Cost about $400 in materials for a four lane track to build plus labor. Took me 80 hours. I'd offer to sell it to you, but the shipping from STL to Seattle would likely be prohibitive.

Re: Which of the rules "in the box" prevents use of lathe?

Why not just make a minimum diameter of 1.18" & .360" wide, then specify "no removal of material from inside the wheels allowed". It's quick and easy to check that with a $20 gauge from Max-V. Our rules also add that the wheels can't be drilled, spokes and lettering must be intact, etc. We don't all...
