Floorboard to Joist Drill Guide - Parametric - Openscad

Description

This Is My Floorboard To Joist Drilling Guide. Its Helps You Make Repeated Drilling Of Holes To Joist As Good As Practically Possible. Previously I Used Just Cardboard As A Guide. It Also Acts As A Spacer Element From Floorboard To Floorboard. Important! To Note The Guide Does Not Eliminate Screwing Into Pipes - If Pipe Network Is Not Straight Or Off Center And Full Of Surprises .Check Before Using This Guide. Its Not A Hard And Fast Guide.! To Use The Guide Enter The Joist Dimensions In The Openscad File And Floorboard Dimensions. This Gives You A Visual Model. Floorboard Dimension Entry Here Is Imperial While Joist Is Metric. All Other Calculations Are Metric. Now Modify Floorboard_Hole_Inboardx_Mm And Floorboard_Hole_Inboardy_Mm And Floorboard_Hole_Pitch_Mm To Suit. Adjust Guide Hole (Guide_Hole_Mm) To Suit. I Found Using A Bradawl To Mark Holes Before Drilling Was Better In Actual Usage. Finally Modify Guide_Endstop_Thickness To Suit. 2Mm Works Well But Older Boards Have Larger Gaps Up To 4Mm. There Are Two Models You Can Produce From This File, One With Basic End Stop And The Other With A Cross Bar (See Pics). To Change Modify The Centerbars= Yes Or No. It Is Best To Print Both Versions In Actual Use. I Have Provided Example Stl Models Of One With Endstop And One With Crossbars For 2Mm Spacing. Finally To Print The Model You Need To Flip It In Z Axis. Usage Notes: The Indentations Are Used For Centering To A Pencil Mark. (Works Best On Basic Endstop Version) In Actual Use I Found It Was Best To Mark The Holes With A Bradawl Before Drilling Anything. Also It Is Best To Print Both Versions (End Stop And Centre Bars). Other Applications: You Could Also Use This For Decking And Any Other Repeated Drill Patterns From Any Edges. Openscad File Included.
