WANTED: spade wood drill bits

Volunteers need 7/8 , 15/16 and 1 inch spade wood drill bits , this is for volunteers doing research on bird house oval hole sizes . and to monitor the oval holes we have . Ok for the spade bits to be dull and worn out . Will only be using them as a go , no go, feeler gauge. This research will be at Outerbridge park , and Rithets Bog . Would also be nice to get enough to give some to H.A. T. I see them at thrift stores and garage sales for about a dollar . could you please donate the above drill bits if you are not using them. To get an idea of how we will use them see the U tube video " oval hole for bird houses " would also like some 1 and 1/8 spade bits to measure the round holes . thanks malcolm cell 250 8126461
