Gary Katz - Master finish carpenter and publisher of THISiscarpentry.com BalusterPro makes building that stairway more heavenly homefixated.com ____________________________________ Instructions for Use: BalusterPro offers calculations for six different common handrail situations which you may encounter.  First, tap the settings button to select your measurement input method, then select the desired type of baluster installation. Use the keypad or sliders to enter your measurements for ‘Run Length’ (distance between the newel posts) and the ‘Baluster Width.’  Finally, just drag the ‘Balusters Needed’ slider to see your required number of balusters. As you adjust the ‘Balusters Needed’ slider, the “Spacing Between Balusters” will simultaneously update. Stop when your ‘Spacing Between Balusters’ meets your specific code requirements. Tap the view button to see a list of all the centers and edges of the balusters. No longer will you need to keep pressing the add button on your traditional calculator to list your centers....they are all shown on one screen! It’s just that simple! You can display your measurements by selecting 1/16, 1/32, or metric on the main screen to determine your precision level. If desired you can also display your result down to 1/64. To do this, once you have done your calculation, simply tap the 'Spacing Between Balusters' result and if possible it will be further reduced down to 1/64 and displayed for 5 seconds. This is handy if you want to cut all your fillets at once as it nearly eliminates cumulative error. Tap the speak buttons at the bottoms of the list columns to have the app speak your measurements. ____________________________________________________________________ Check out my other construction related apps...StairBuilderPro for a stair stringer layout tool & TilePro for a simple tile layout tool. ____________________________________________________________________ Check out the video demo at my website to see BalusterPro in action.
