David Posted April 3, 2005 Report Share Posted April 3, 2005 (edited) Hey, don't know if this should be in here or chit-chat. Anyway you may remember me asking lots of questions in chit-chat about making a crank extractor for my GCSE project. Well its finally done! Its not perfect at all, but seeing as its my first time using a lathe/milling machine etc I think ive done ok. While manufacturing the tool I came accros the problem of not having a die stock big enough to hold the M22 die so I had to make a one myself: Edited April 3, 2005 by David Quote Link to comment Share on other sites More sharing options...

Sam Nichols Posted April 3, 2005 Report Share Posted April 3, 2005 Just having a second look at it... although it's still a brilliant job and you're obviously very skilled with the old lathe and milling machine... Theres not a lot of innovation there, I mean you've just copied an old design really. Don't get me wrong, I still think it's a top job but theres nothing special about the design - sorry! Although I suppose why fix what isn't broken... So I have just contradicted myself... But yeah. (Y) INNOVATE :) Quote Link to comment Share on other sites More sharing options...

Nice work, I'll show it my dad in a min. Quote Link to comment Share on other sites More sharing options...

I have though used a deeper pictched thread on the tool which makes it stronger then most you can buy. The 'standard' thread is usually 1mm pitch but I used 1.75 (Y) Quote Link to comment Share on other sites More sharing options...
Mark W Posted April 3, 2005 Report Share Posted April 3, 2005 Why not try making one for a crank with a stripped extractor thread? I know I'd love one (Y) With my cranks, if I strip the extractor thread it generally requires me riding it without a bolt in just to make it drop off, but it'd be a lot easier if there was a tool out there that used the same principal as a normal crank extractor, but the main body of the extractor (the bit that usually gets screwed into the crank extractor threads) had some kind of clamping system to clamp it to the crank arm?

Basically it will grab your crank and pull it away from the axle Quote Link to comment Share on other sites More sharing options...

JT! Posted April 4, 2005 Report Share Posted April 4, 2005 Very nice. Looks like it could take a beating, tools these days arnt made very stong at all. Its not like they need to be super light like bike parks. :lol: Quote Link to comment Share on other sites More sharing options...
David Posted April 4, 2005 Author Report Share Posted April 4, 2005 Thanks for all the comments. I'm currently designing a few bits and bobs (tools and bike parts). Once I have time I will knock up a few models/prototypes on the cnc machine. Nothing special as im still learning everything! Hehe.

Luke Rainbird Posted April 4, 2005 Report Share Posted April 4, 2005 Nice! Wish I'd done something for my bike now, tensioner or something perhaps rather than a bloody wakeboard rack! Fancy making me a tensioner for my new singlespeed rig?! :S" Top job Mr. Dave :lol: Quote Link to comment Share on other sites More sharing options...
on that? u must be joking Posted April 4, 2005 Report Share Posted April 4, 2005 I have though used a deeper pictched thread on the tool which makes it stronger then most you can buy. The 'standard' thread is usually 1mm pitch but I used 1.75 :D ← :ermm: Not saying anything else cos i remember posting a load of poo when trying to help last time. It looks like a nice job - i especially like the fact you knurled that bit of it :P Andy Quote Link to comment Share on other sites More sharing options...
