opticsguy Posted September 12, 2009 Report Share Posted September 12, 2009 A question about JB WELD. I have a 1" long 1.5" diameter steel rod JB Welded to a brass plate. How to seperate the two parts without ANY damage? Any practical experience out there? Thanks for your assistance!! Quote Link to comment Share on other sites More sharing options...
billschwindt Posted September 12, 2009 Report Share Posted September 12, 2009 I would try a little heat from propane torch Quote Link to comment Share on other sites More sharing options...
Jim Gaspard Posted September 12, 2009 Report Share Posted September 12, 2009 A Dremel tool with a cutting disc at high speed should be able to separate the two metals, a little bit at a time. I have used JB Weld in joining my front metal grills at the seam, then used my Dremel tool to cut and sand down the epoxy once set. It really throws up a dusty residue, but the epoxy is no match for the cutting disc. I can't think of any tool small enough to work in a tight application other than a BFH. I'm not sure heat will burn out the JB Weld, but you might do a test burn on a cured glob to see if a propane or acetylene/oxygen flame temp will break down the weld. And remember brass has a lower liquid temp than steel. Good luck. Quote Link to comment Share on other sites More sharing options...
grey beard Posted September 12, 2009 Report Share Posted September 12, 2009 Depending on the degree of accessibility available to you - space and angles available, etc. - a high speed whiz wheel cut-off disc culd be a viable option. These discs are typically very thin and are made to cut sheet metal and the like. May be worth a try if you have one in your arsenal. Good Luck Quote Link to comment Share on other sites More sharing options...
