How to Ream a Bicycle Head Tube and Seat Tube

It's time to do some reaming, facing, and slotting on my mountain bike frame! First, you'll see me ream and face the head tube, then I ream the seat tube, and then I slot the seat tube.

Here's the podcast episode I mentioned with Drew Guldalian of Engin Cycles in the video: https://cobraframebuilding.com/podcast/ep-11-drew-guldalian-of-engin-cycles

So, for the head tube reaming and facing, I'm using a Park Tool head tube reamer/facer. In case you're not familiar with it, I give some background on the Park Tool reamer/facer, then I show the process for how to get a nice full clean up and make sure the headset will fit snug inside.

For the seat tube reaming, I used an adjustable reamer with straight blades that I'm actually not a huge fan of—but it was affordable. I also talk in the video about why helical reamers are better for seat tube reaming if you can afford one.

For the seat tube slotting operation, I use a homemade seat tube slotting tool that I made based on one I saw Drew Guldalian from Engin Cycles using.

Here is the playlist of the whole Hardtail Mountain Bike Frame Build—I'll keep adding to it as we go: https://www.youtube.com/watch?v=0okGsgYBObc&list=PLh0BOtXK_s5edhuy-y5C6E41UT-ZLGukE
