With the torch, or like a grinding wheel or something?

If I use the torch, do I have to worry about going through the tube, or just get it nice and hot and give it a good whack with the BMFH.

Thanks

Tourch them off, then use a grinder to clean it up.

Torch just the welds and whack, or the whole deal?

The one side i started on is just a 1/2" gob of nasty metal so that one will suck, for the second I want to do it right.

Also do i have to worry about getting to hot?

Thanks

Just tourch as much as you can, if I remember right there is a bottom on the perch. Yep a big gob of slag. I cut on mine for about 10-15 min to try and clean it up.
The tub is very thick, just keep the flame of the tube as much as you can.

If you have the cutting tip in and have the gas set correctly the axle will not get overly hot. Make sure to have enough pressure and have the "blast" button set correctly. Test it on some scrap. After getting the main puddle hot you should be able to move about an 1/8 inch a second. I point the flame toward where I am cutting at a 45 degree angle away from whatever it is attached to if possible, lay on the blast button and go go go. if you get a spot where the cut drips together keep going. You can hit it with a hammer later and it will easily crack. HTH

If you were trying to save the perch, I would go with a grinder. I used a grinder to grind off the welds, then used a thinner 4 1/2" disk (like a cut-off wheel) on my grinder to cut under the perch. You'll noticed that the weld goes into the perch some. Then the BFH to pound it off. I reused mine.

Look on the coloradok5.com in the buildup section....they show a 14 bolt getting new mounts <homebuilt from a 3x3 tube i think>

It's not that hard to just blow off the weld with a torch....the perch and the weld are different types of metal

It should only take a couple of minute to blow out the four welds then take a hammer to em' to knock them off.

Don't worry about the heat, you have to sit there a long time to heat up the tubes enough to hurt them
