You may need to remove the tub from your Whirlpool or Sears Kenmore washing machine for some repairs. You will need a special spanner wrench. They can be ordered for about $14 US plus shipping. I needed one immediately and decided to make my own. The photo shows the tub nut on the drive block. Both are shown removed from our direct drive washing machine. The nut is inside the tub and under the agitator. Space is limited by the sides of the tub to about ten inches between the nut and the side of the tub. The nut is also a few inches below the top of the tub. It is difficult to access with anything but a spanner wrench designed for the job.
I liked the end paragraph of step 1: you and me are twin souls! (for some things).
I'm totally with you Phil on not publishing projects of limited scope, either in their materials, utility, or methods. I've had requests to write up some of my hair brained stuff and I won't because I think it is just too odd to duplicate.
Even I wouldn't do a lot of it again! Now if you wanted to eliminate welding from your project you could have simply drilled holes through the pipe and passed a bar through as a handle. Though I guess drilling through rounds isn't easy for everyone to accomplish. Center punch, mount pipe in vise attached to press, spotting the hole doesn't hurt either. Or just used the pipe with a pipe wrench. That is universally doable. Have to tension the wrench if you want to hammer it though. Been there, done that!
Maybe you don't know about staining and scribing metal for layout Phil? Staining is usually done with an ink. Dykem Blue is the most popular brand. But any permanent magic marker appears to work. Personally I usually use Marks A Lot. Not that I don't have a bottle of real marking ink too, just well it can be a pain to use.
If you want to see about tapes and pipe check out CURV-O-MARK WRAP-A-ROUND which is an interesting aside about pipes and a tape like device. I think you may enjoy it. It is really esoteric stuff though.
