[Q]: [header] How to bend rebar [title] Understand the structural issues possible with manually-bent rebar and know how to avoid them. [step] When you bend metal, you naturally weaken it. When done correctly, however, you can minimize damage and still get the shape you need to complete the project. <sep> (A) [substeps] Badly bent rebar acts as a buffer for the metal particles of the laser beam. The piece of rebar you are bending dissolves when squeezed into contact. (B) This effect is part of the re-bend method. The process is a little different than rebending a rubber band, but the difference is that you bend it in half by simply opening up a v on each end. (C) Because of this, it's important for you to know how to modify the shape you want the rebar to be. If you have a badly bent rebar, you'll likely create grooves in the rebar that introduce excess material. (D) Keep the following in mind as you work : [substeps] Always note the grade and size of the bar you're bending, checking against the equipment you're using to ensure it works. Check with your project engineer to ensure your bends meet the minimal internal bend diameter.
[A]: D


[Q]: [header] How to divide dwarf iris [title] Choose the correct time to divide the rhizomes of the dwarf iris. [step] Divide irises during the summer dormancy period into early fall, at least 6 weeks after the last blooms have faded. This gives the newly formed rhizomes time to become established. <sep> (A) [substeps] Other ideal times to divide the iris is between june and october/march between frost dates, and so forth. [title] Take the rhizomes with you if you decide to work in a garden. (B) [substeps] This does not work if the climate is generally safe for roaming through the forest during the summer. [title] Divide the rhizomes in the fall or early winter. (C) [substeps] Irises should be divided every 3 to 4 years or when the middle of the clumps look bald. Irises may indicate they need divided when the amount of blooms decrease from year to year. (D) [title] Divide the rhizomes of the dwarf iris in fall/early spring.
