How to remove GLUSHU
Using nippers, cut the metal shoe from the cuff, leaving just the cuff on the hoof wall.
Using a coarse rasp, remove the remaining cuff, or, using a draw knife, cut the cuff from the hoof using downwards strokes along the glue lines (this is very easy to do)
Remove any remaing cuff or glue with a rasp
You are now ready to fit another GLUSHU.
