orange peel attempt

admin

Did this to cap a spiral stair postx.  I did not want a ball and it is a 6 inch post, so a ball would be massive. Google'd the formula for making the pattern.  It is recommended 6 segments minimum, however, more segments would have been better for a smoother dome.  I worked a long time to get it roundish.  Initially, I had planned on making it directly on the spiral, glad I didn't. I would have been rotating the spiral a few inches at a time to get comfortable.  Anyway, came out well. Welded a positioning ring inside and jb weld it to the post. Attached Images

Reply:I think it turned out real nice.  They do sell 6" half ball? Post caps like that.  Just in case you want to save some time.  But I know fabricating stuff is half the fun sometimes.
Reply:Thanks.  Better planning and I would have ordered a dome.  Initially I wanted to make it directly on the spiral.  Then too late in the game to order.  Perhaps, a task not to be repeated.  However, I also hate the fit of generic junk cast iron parts.  I have a some items from King Metals that were to expensive to send back, yet a bunch of work to make look satisfactory for me.

Reply:Looked pretty rough on the cuts, still a bit rough on the in-process grinding pic, pretty nice on the final painted pic.Looks like you did some 'heat-n-beat' to fold over the segments, right?Some google-fu turns up a bunch of post pipe caps.http://www.sharpeproducts.com/store/...pipe-tube-capshttp://nedsstructuralpipeandsteel.co...me-post-caps-2http://www.prescottsupply.com/6inchsteelpipecaps.aspxetc, etc, etc  No endorsement implied, yadda, yadda, yadda.  The best laid schemes ...

Reply:Thanks for the links.  Ironically, I did not see any for 6" tubing.
Reply:King metals has them in 6"
Reply:The link I posed was for pipe, not tubing.  You are right that caps for tubing would be difficult to find.  I did not realize you were using tubing.
Reply:King does sell the hemispheres in 6".  Thanks for all the links.
