Hi, in a recent quest to drop a Model A front axle I came across a problem. I built myself a pretty nice jig out of some stock I had laying around (actually stainless I got out of the dumpster at work), but when it came to heating up the axle to drop it, the best I could get was a dull red out of it. That was using a dedicated Smiths cutting setup with about a 1/2" tip. So then I switched to a 5/8" or so rosebud tip borrowed from a friend. That got it a little hotter, but still not enough to drop the axle very well. A local machinist was telling me I could use a propane weed burner for this job. He was saying he has used them to heat heavy iron castings to prepare them for welding, as well as to melt large amounts of aluminum. I was looking at this one: http://www.northerntool.com/shop/to...78?cm_sp=Upsells-_-Top Sellers-_-Product Page . Do you guys think this would do the job? am having my doubts after seeing how much a rosebud struggled with the job. Also, he was saying that you could use chunks of drywall to create a box around what i was heating to keep more of the heat in. Obviously the box would burn away after a while, but it would keep the heat more localized while it lasted. Any thought on this, or what else I could do? Besides using a second torch. Thanks.
