Have the Covid-19 lockdowns still got you bummed out? Have you had a long enough winter? Are you ready to put some metal together and build something awesome, while documenting the process and having fun?!

Well, ladies and gentlemen, boys & girls, it's finally here! Announcing your 2021 DIY Go Karts Build-Off Challenge!

After the mayhem and burnouts of last years contest, and the stress of COVID, we're ready for another round! So dig out that pencil and slide rule, buy a box of Tylenol, and start the coffee pot! The contest is ON again! Starting NOW!

Until December 31, build the coolest, craziest, most incredible motorized mayhem you can muster, for the title of 2021 DIY Go Kart Build-Off Champion!

Okay- so here's the SHORT VERSION of events to come.

Last Year's Builders

If you were part of a previous year's build and did not complete, you're still eligible. Please update your log and have a moderator move it back to the "Build Off" forum instead of the DNF forum.

New Builders
Effective immediately, those entering the contest will start a build thread in this forum subcategory . To start your thread, you'll need to post a pic of your primary parts source(s), pile, donor machine(s)... In that picture, you need to have a sign that reads "DIYGK 2021 - SPARKALATOR!"


Update Us!
You'll need to keep the build thread updated with lots of pics and info on how you're doing. The goal here is to show your progress and inspire others! And, it'll help keep you motivated!

The votes will be tallied based on several categories this year, such as "difficulty", "innovation", "awesomeness", "well updated build thread", and more. Those scores will all fit into the final tally! So update your builds soon, and update often!

After the contest deadline, the voting system will be unlocked, and all registered members will have 2 weeks to examine the entries and vote for their favorite builds.

More Info
Any DIYGK member may enter the Build-Off, so let the sparks fly!

Please carefully read the details below before proceeding. Good luck to all!
