  1. My solution is to take a good deep non sparking welding heat with any good flux and very lightly with a 1-1/2# or so hammer and, if its a top seam, lightly chamfer the edges, then forge the chamfers back out. You are really moving a very little material, then moving it back. Most of the time, this is enough to remove the seam. Wire brush after reaching your welding heat, then forge is pretty critical too. To be clear, this is done after you do your initial problem and need to heal the seam deal.

  2. Fear,, A strange thing with me has become a fear of heights. I've been driving the Colorado high mountains all my life in every conceivable weather situation and loved every trip. But for some reason these last 5 years a fear of heights has been growing and its becoming worse. Strange, I often pick longer routs just to miss the fear deal.

    The problem is that these same words often mean different things in different situations

    Most Every thing I said has to do with the building codes, UBC? As best I know they haven't changed. Again from memory  ;)  Their are 3 types of defined curved stairway rails, a spiral, a sweep, and a winder. I don't remember the differencs. As I remember all three have this in common for the inspector: the rise and run are named and the measurement is taken "X" inches from the outside edge of the center of the vertical support. Seems that distance was 6 or 9 inches and I don't remember the rise and run at that point. The other commonality was they all three have a fixed radius. I've actually never done a spiral type on my own. I have done a few as a helper for other smiths. Think fireman's pole with a 36" or so tread length that has a section of pipe at the inside of the tread that slides over the center pole. The two I've done on my own were built around an "ugly" log center pole with half log treads mounted to the big ugly via a blind tenon and wedges in the mortise.  Both had an ever changing radius and were approved by the inspectors before I did them. On both, the inspector( the same for both) said an ever changing radius did not fit code, but he would approve them anyway as long as I met the rise and run heights from the outside of the "Big Ugly". The inspector may or may not have been the one who associated a volute with a sea shell and that it had an ever changing radius. Beyond that, my last math was sophomore year, '67, engineering at U Colorado and I have very little remembrance from then concerning this.  ;)  Heres a pic in progress of my second one. It's actually a half rise to a landing, then a straight run to the second floor. There lies the "Big Ugly, the treads and two of the forged iron stringers being fitted.  I milled the treads with my alaskan mill and the rest of the log work was done by a good friend. Design by me.

  4. I think a volute has an ever changing radius, at least thats how I think of it,,, like a sea shell. A spiral on the other hand has a constant radius. 

    There are 3 types of spiral stairs in the building codes(UBC? and all are based on a constant radius, or there used to be,, a sweep, a winder and a spiral. There are no specs for a volute. It's always a trip with the inspectors when getting one approved. Always best done before you start the job.

  5. The cool thing was the fit of the spirals to the wood cane. The cross sections of my two spirals were slightly smaller than the cane, which, which was tapered. The wood guy literally screwed the cane down into the socket and removed material as needed so there were no gaps between cane and iron and it was slightly inset into the wood. We decided on rivets over screws because of potential wood shrinkage. Rivets could be tightened up whilst screws might strip out.

    Lol, a good memory from a far away moment in time!

  6. I did a foot for a cane once. A biker friend had an accident and his friend, another biker wood carver had me forge the cane end(foot). It was an eagle claw holding a rock/Earth. the top of the claw became the socket and there were two straps that spiraled up twards the handle. He then carved the cane to fit my iron and did a bronze cast harley for the handle. The spirals had rivit holes in that were matched side to side. He then rivited thru these straps to secure it to the cane. Sorry no pics, but a cool project.

    I hadn't thought of it in years, but the cane talk reminded me. Thanks!

  7. nice bunch of stands.

    somebody got an idea or tip?

    My preferred way to mount my anvil to the stand is to inlay the anvil into my stump. You could do the same. All you need is a wood chisel, a hammer and some fine sand. Trace your anvil base onto the stump and chisel it in. I chisel mine about an inch or so deeper than needed, then put the fine sand in the void. The sand does a few things. It is far easier to level your anvil in the sand than to make a level saw/chainsaw cut or chisel the bottom level, and the sand deadens the ring of the anvil. Make it a close fit and you won't need any external fasteners to hold your anvil firmly in place. 

    Rich_c,    nice stand. You can make a bracket that fits over your all thread that can hold a hot rasp or a favorite hardy tool.
