2023 Subscriptions ginty001 Posted February 6, 2016 2023 Subscriptions Report Share Posted February 6, 2016 My new TT frameset needs the carbon steerer to be cut and the wee star thingy installed in it. Is this something i should be doing myself, or a task better left to to the LBS? Any advice welcome? Cheers Ian Quote Link to comment Share on other sites More sharing options...
2023 Subscriptions PaulL Posted February 6, 2016 2023 Subscriptions Report Share Posted February 6, 2016 Installing the star-nut needs a tool, i have one you could borrow. Best to get the your LBS to cut the steerer with a carbon saw blade but you can just do it with a junior hacksaw and some tape, but not worth the risk of some splitting. ginty001 1 Quote Link to comment Share on other sites More sharing options...

Life Members chung Posted February 7, 2016 Life Members Report Share Posted February 7, 2016 Iain, As Billy said, if you fork steering tube is made of carbon then you ABSOLUTELY should not have a star nut (it's for an alloy steering tube) what you should have is an "expanding bung". Check with Planet-X for this if they've given you the wrong parts :-/ As for cutting the steerer, like Paul said, I would suggest to go to a bike shop (unless you have the right tools) where they should have a steerer cutting jig which clamps onto a vice & carbon specific saw blade for a proper job done. Good luck & have fun with your build! Cheers Chung Quote Link to comment Share on other sites More sharing options...

2024 Subscriptions Darryl Gunson Posted February 7, 2016 2024 Subscriptions Report Share Posted February 7, 2016 Hi Ian Hack saw is fine, but can be a bit tricky getting a clean and straight cut. A plumbers pipe curring tool had been recommended to me by a few people, although I haven't actually used one, yet. Quote Link to comment Share on other sites More sharing options...
Colin McPhee Posted February 7, 2016 Report Share Posted February 7, 2016 Ian be careful doing this yourself as the dust caused when you cut carbon if inhaled is very bad I wd get a shop to do it Quote Link to comment Share on other sites More sharing options...
paul mcskimming Posted February 7, 2016 Report Share Posted February 7, 2016 * Scouse accent * (no offence to Scousers) CALM DOWN CALM DOWN. Chung is correct, no Star nut in a carbon steerer Iain and Park make a snazzy saw guide. Pipe Cutter no use as carbon destroys the blade. Put insulting tape around steerer (stops splintering) and use 32t hacksaw blade. Finish off edge with a fine file. Measure 10 times (this induces sweaty top lip) and cut once. good luck chung 1 Quote Link to comment Share on other sites More sharing options...

2023 Subscriptions George Posted February 7, 2016 2023 Subscriptions Report Share Posted February 7, 2016 I would just leave it & stuff Nutella down the protruding steerer tube. Ideal for if you get peckish during a 50. ginty001 1 Quote Link to comment Share on other sites More sharing options...
DavieB Posted February 7, 2016 Report Share Posted February 7, 2016 It may upset Park tool shareholders but you can use the stem clamp as a cutting guide.... Quote Link to comment Share on other sites More sharing options...
2023 Subscriptions Tom Hill Posted February 8, 2016 2023 Subscriptions Report Share Posted February 8, 2016 Iain I have a hacksaw picture frame cutting jig that I have used on several steerer tubes with no problem. You are welcome to use this. Also I have a carbon-specific expanding head-tube nut/bolt assembly that you can swap for the star nut, if you wish.

Committee Alan McLean Posted February 12, 2016 Committee Report Share Posted February 12, 2016 I have Park carbon steerer cutting jig and hacksaw which you are welcome to borrow. I bought this because everything else has resulted in squinty cuts including the integrated seat mast on my Giant. That was very sweaty. It actually does not matter if the cut is out of square by a mm or so but, even when it is hidden by the top cap, you will know it is there.

2023 Subscriptions martin Posted February 15, 2016 2023 Subscriptions Report Share Posted February 15, 2016 Thanks Paul. Will bin the pipe cutter idea then :-) Works great on alloy steerers though. Discovered the hard way that carbon is tougher. paul mcskimming 1 Quote Link to comment Share on other sites More sharing options...
