So the heatsink is just a big aluminium (possibly a copper core) cylinder about 12mm long and 18mm diameter, threaded to screw into the torch body. But over time it unscrwes slightly and loses the thermal path to the outside world.</p> <p>That and the outside is partialy covered with rubber to help with the bar/helmet mounts, so I need to make up for that. </p> http://singletrackworld.com/forum/topic/homebrew-lights-weve-not-done-this-for-a-while#post-941322 Tue, 15 Dec 2009 11:41:02 +0000 joemarshall 941322@http://singletrackworld.com/forum/ <p>Is the back of the cree star not insulated from the contacts? On the ones I have, it can be pressed right up against the heatsink with no worries about insulation. I know some boards may be different though. If it is, I would stick some thermal paste under, but make it as tight a fit as possible - thermal conducting paste isn&#39;t going to be as good a conductor of heat as direct contact is it?</p> <p>Assuming the heat is getting to the heatsink (or you work that one out) Can you just make some holes in the casing so that the heatsink is exposed directly to the outside? That way you&#39;d be actually using it as a heat-sink, rather than just somewhere to store up a bit of heat before chucking it out through the casing.</p> <p>Joe </p> http://singletrackworld.com/forum/topic/homebrew-lights-weve-not-done-this-for-a-while#post-941280 Tue, 15 Dec 2009 11:28:08 +0000 thisisnotaspoon 941280@http://singletrackworld.com/forum/ <p>hmmm, the heatsink screws into the body so I&#39;m guessing the paste will be displaced as it tightens (but still take heat away though the bits with no metal/metal contact?</p> <p>Could wrap some thin copper wire into the threads before screwing them together maybe? </p> http://singletrackworld.com/forum/topic/homebrew-lights-weve-not-done-this-for-a-while#post-941269 Tue, 15 Dec 2009 11:24:18 +0000 snaps 941269@http://singletrackworld.com/forum/ <p>I&#39;d use this for both applications <a href="http://uk.rs-online.com/web/search/searchBrowseAction.html?method=searchProducts&amp;searchTerm=554311" rel="nofollow">http://uk.rs-online.com/web/search/searchBrowseAction.html?method=searchProducts&amp;searchTerm=554311</a><br /> Then drill &amp; tap a small bolt into the heatsink to get the electrical connection. </p> http://singletrackworld.com/forum/topic/homebrew-lights-weve-not-done-this-for-a-while#post-941213 Tue, 15 Dec 2009 11:08:36 +0000 thisisnotaspoon 941213@http://singletrackworld.com/forum/ <p>rightey, my lights are hot on the inside and cold on the outside (it&#39;s melted the insulation on the wires!)</p> <p>So, to improve the heat flow to the outside I recon I need 2 things.........</p> <p>Some electricaly non-conducting but thermaly conducting paste to put under the LED (cree Q5) to transfer heat to the heatsink better.</p> <p>And some thermaly and electricaly conducting paste to take heat from the heatsink to the outer caseing (there&#39;s only a +ve wire to the driver, the earth comes back through the caseing).</p> <p>Where can I get such magical concoctions?? </p> http://singletrackworld.com/forum/topic/stw-super-thrifty-week-credit-crunch-biking-holliday/page/2#post-452401 Tue, 16 Jun 2009 23:08:04 +0000 thisisnotaspoon 452401@http://singletrackworld.com/forum/ <p>psycle, e-mail recieved an oppinions of beer dully noted :p </p> http://singletrackworld.com/forum/topic/stw-super-thrifty-week-credit-crunch-biking-holliday#post-452189 Tue, 16 Jun 2009 22:09:14 +0000 psychle 452189@http://singletrackworld.com/forum/ <p>That's what I'm talking about, looks excellent!

Its often better to use 1 or 2 locations as a base and explore from there. </p> <p>With a bit of route planning you could easily have 7 days worth of great rides in any of the York Moors, Dales, Peak District, Lake District, South/North Downs. i don't really know Wales and Scotland other than the trail centres which get very samey if you ride them every day.</p> <p>If you compare like for like, i'd imagine the alps holiday is more expensive but not massively so. You need extra money for travel and lift pass and thats it. </p> http://singletrackworld.com/forum/topic/stw-super-thrifty-week-credit-crunch-biking-holliday#post-440775 Fri, 12 Jun 2009 14:02:56 +0000 mark_b 440775@http://singletrackworld.com/forum/ <p><blockquote>8 Day roadtrip, cramming in as much riding as possible, staying in hostels/camping/bivying.</p> <p>Possibly in Scotlandshire as it's far enough away from most of us to count as a holliday</blockquote></p> <p>Sounds like a plan - hold on - i'm already doing it next week !</p> <p> <img src="http://singletrackworld.com/forum/my-plugins/bbcode-buttons/default/icon_biggrin.gif" title=":D" class="bb_smilies" alt=""/> </p>
