Problem:
Need a 4 foot board 3.5 inches wide on one end and 3' 5/16'ths on the
other. I have a taper jig I bought from Delta (I think) but it's not
big enough.

Questions:
Do I not know how to use the taper jig I have?
Do I have to build my own? If so, where can I find plans? Or should I
make a larger model of the one I bought?

Solution(s):
Hopefully the responders of this post will provide.....
