Pro-tip for those like me who can't afford Park Tools: I use an old stem as my saw guide.

Because of videos like this I've been able to build my own aggressive hardtail from scratch
Very educational
Thanks GMBN tech

My hack method to install a star nut is to use an EMTY co2 cylinder with a piece of masking tape for depth. It's the perfect diameter and the shape of the base perfect for centralizing the nut.

When you pull the fork out of the saw guide make sure you immediately turn the fork upside down as you're pulling it out rather than standing it up straight. If you stand up straight, all the metal filings that are inside the steer tube will fall out the bottom of the steer tube and quite possibly land on top of your stanchion seals

At 7:46 you say the steerer should sit below the stem. I've always been told it should be above the stem so that all of the stem clamp can then clamp against the steerer tube giving a more secure fit & also the top of the stem then won't get compressed narrower than the steerer. When the steerer is above the stem as I suggest, an appropriate stem spacer should then be added on top to give you that approx 3mm gap between top cap & fork steerer to allow take up of slack.

Great vid. To help with the metal filings, pop the packaging plastic bag back on the forks before you cut and file away

I worked in 2 pro shops back in the 90's, never seen a proper crown removal tool. Learn something new all the time👍 Also I've noticed over the years vise is at the end of bench nxt/over a trash can. Helps with the mess.

Hey Doddy, I used an older video of yours recently before fitting some forks and used a bag to stop swarf getting on the stanchions. #GMBNTech - One tip I have is that you’ll get swarf in the steerer tube when you cut it so I recommend inverting the fork to clean it out once you’ve cut it. Keep up the good work.

Funnily enough yesterday i watched the verision of replacing forks from 2 years ago.

[RicardoPetrazzi]

I needed this december! But I managed to sort it out by going back to some of your previous videos as well as the one by Park Tool.

Scratching the fork or crown race is not, "damage."
I've always used a flathead screwdriver, sure it scratches up the fork, but it's not damaged. Nobody ever looks down there anyway.
25, 000 miles since 2009 and no issues. I also installed star nuts with a block and hammer, before Sam Pilgrim was Youtube famous.
Made a headset press for $10 at the hardware store with a long bolt and various washers and lugs.

I am going to try old vacuum pipe for installing the race.

[alevadid]

Great video. Very thorough. I like the simple explanations and the fact that it allows how you can do this with the tools you've probably got already or ones you can get hold of relatively easily, as well as the technically correct way of doing things. Kudos.

[smallhatshatethetruth]

I just got a delivery of a new fork yesterday :). Good advice with not pressing the pipe cutter too hard. I did that with my handlebars and the brakes were a pita to get back on.

Here I am watching GMBN tech at 2 in the morning. Videos are great

[rogerjoesbury]

Thank you for the video, you explained all about it and why . Also emphasized the problems that may happen. Without being condercending .

[johnnyappleseed]

Right on bro brah, got my forks cut right on the money and assembled.
Thanks for the heads up!

[benconnelly]

Already know how but just love watching a good bit #GMBNtech cheers doddy

[muehtra]

Great videos as usual !!! Keep going !! Right on time i will replace my fork in few weeks just waiting for the fork. Would be great if you put a list with links for differents tools in the description.

[danaltaras]

Yikes!
And I thought I could just order in a fork and slip it right on O_o
Wow, that's definitely cooled down my jets
