Idle Time And Just Thinking
We are having some unusually cold weather here in West Texas. 88 degrees on Saturday March first, and a high of 23 on Sunday and only 12 this morning, Monday.
So, I am house bound and doing some thinking. I have an idea and it is admittedly only an idea. If you happen to be familiar with the Incra LS TS system as well as the Incra Express sled you will know what I'm going to be talking about.
To start with the Incra fence positioner is extremely accurate and works just fine. My problem is with the scale on the fence that is attached to the V27 miter gauge, and the gauge is attached to the sled. The template that rides in a slot on top of the fence with the scale on it is, for me anyway, hard to see and is not nearly accurate as the LS positioning concept.
So, here is what I'm thinking about. What if a person were to cut a piece of material, maybe some MDF, a piece of extruded aluminum would be better, that piece, lets call it a tab, is just the length of the distance from the blade of the saw to the right hand edge of the sled. In this idea, the sled is positioned on the right hand side of the TS blade. Then with the Incra fence of the LS system set against the right hand edge of the sled, insert a template into one of the slots in the LS carriage that is marked in inches and set that template to zero. Do this to interfere with the setting of the primary scale. Then, for example say you want to cross cut a workpiece that you want to be eight inches long, you set the LS positioner to eight inches on that secondary scale and move, what we are calling the tab, over to the right so it makes contance with the Incra fence. over to the right to contact the fence on the LS system leaving an eight inch space between the left edge of the tab and blade. Some minor calibration would be needed but you should, in theory anyway, be able to then utiiize the accuracy of the LS positioner and not have to use the scale on top of the fence that is attached tot he miter gauged. The problem of course is that wood is so unstable that the calibration will not stay as set and is why a piece of material other than wood would be a better way to go. A simple piece of aluminum angle would work well or so I am thinking.
I'm not sure yet what to do with the limitations of the end of the fence on the miter gauge coming into contact witht he fence on the Incra LS fence. Maybe just moving the fence over to the left and adding a sacrificial sub fence might work. Still just thinking, and idea is applicable to 90 degree cross cuts.
Anyway, just thinking while I'm waiting for things to warm up, supposed to have a high of 65 tomorrow. I bet I have some broken faucts as I left them hooked up and loaded Saturday evening not knowing that the cold front was was coming in, Oh well, such is life.
