Derby Weight Drill Guide for Pinewood Cars

Using Derby Dust’s Derby Weight Drill Guide, you can drill virtually all weight hole designs.  First version will be designed for BSA distances.  If enough people request a variation, we will design one for extended wheelbase  Holes will be centered and space properly for nearly all basic designs.  Using our unique system, you can drill perfectly aligned holes as long as your bit will allow.  Use tungsten cylinders, lead, or steel weights to complete your car design.

My son came up with this the Derby Weight Drill Guide design, drew it in CAD, then printed with a 3D printer.  First ones are going to be RED until it runs out, then we might move over to our traditional green.  We will offer it in digital downloads for those DIY guys.  Our program is running 5.75 hours per print.  Pared with a brass drill guide to ensure it will last the lifetime of your needs.  We read the “other guy’s” Metal tool review on Amazon.  We fixed his customer complaints with the addition of the drill guide.

Derby Weight Drill Guide is made with “green” PLA plastic which is derived from sugar cane.  D durable enough to use over and over.  Nothing else like it on the market.   Drill holes are oversize 1/32″ of an inch to ensure no binding with manufacturing differences in jobber bits, and plastic cooling during printing.  Derby Weight Drill Guide will support the 25/64″ bit that some tungsten manufacture’s recommend.  HOWEVER, the drill guide will only accept a 3/8″ bit.  We have no problems with our tungsten cylinders fitting in a 3/8″ diameter hole.

Use our COG stand to ensure the proper weight placement for maximum speeds!

Drill the following patterns:

  • 3x 3/8″ weight holes from the rear which will are raised enough to go over axle slots and drilled axles
  • 3x 3/8″ weight holes from the side
  • 9x 3/8″ weight hole pattern for the bottom
  • 2x 1/4″ peep holes for those packs that require the visualization of BSA axle tips.  Also great way to glue your axles down after tuning.
