cougar69 Posted January 5, 2012 Report Share Posted January 5, 2012 I want to replace (weld) the bolt handle on my 03/38 turk. I know a heat sink has to inserted in the bolt. Can I use an alum rod instead of copper? I only ask because I have free access to the alum rods. Thank s in advance. Quote Link to comment Share on other sites More sharing options...
rustvyper Posted January 5, 2012 Report Share Posted January 5, 2012 I use a steel rod & it works fine (although I use a long one). The k coefficient of steel is only 43 W/(m.K) while aluminum is 250 W/(m.K). Copper is the best with a 401 W/(m.K) coefficient, but I think you'll be fine. Just you a liberal amount of heat paste. If you're tig welding, a good, quick job usually heat my bolts so little I'm doubtful a sink is required at all, but I use one anyway.

tinkerfive Posted January 5, 2012 Report Share Posted January 5, 2012 I've used an air nozzle with a constant flow blowing inside the bolt Quote Link to comment Share on other sites More sharing options...
Spiris Posted January 6, 2012 Report Share Posted January 6, 2012 I have the aluminum heat sink, but I try to drape some wet rag on the lugs and heat sink using my old school welder. Spiris Quote Link to comment Share on other sites More sharing options...

Spiris Spirits, are you using an arc welder? If so what rod do you use? Bobg Quote Link to comment Share on other sites More sharing options...
