Enter the gmod server browser and look for the sledbuild tab. These servers are what we will be talking about through this 4-step guide!

After joining a sledbuild server, spawn sled-sized items and an airboat chair. With these materials, you'll be doing this: In no time!(if there's not a picture there, let me know.)

Use the items and chair you spawned and freeze them in the position you like. Then, Weld every piece together and unfreeze them.

Now, place your sled on the ice at the race track and wait for the countdown. When the timer hits zero, you and your sled will move through the track at variable speeds. There will be other contestants participating, so you must race the through the track on your uncontrollable sled! I find this the most fun part. after the race, reset by going to the console and typing, "kill". That's all you need to know from MrExplodey for now!
