The marron colored hitch pitch pin felt needs to be replaced. There are so many holes on it to be transferred on new felt. For accuracy and better fit, the shop owner suggested that we use mylar as a templet. With a good hands on skill, the mylar step can be eliminated, not here, though...
The plate has been refinished, all shiny shiny. Spray adhesive on back of old felt, glue it on a piece of mylar or similar material that's on the stiff side. transfer holes through old felt to mylar, try on plate for fitting. If some holes don't fit, mark and re-punch holes till the template sits flat in position. For the missing holes on old felt, the mylar is placed on top of those hitch pins, a pencil is used to rub from top to make a mark for the punch.
Spray adhesive on top of template, glue new felt on so the glue is on the bottom of the new felt. Flip up side down so the mylar is on top now, transfer all accurate holes to new felt, fit again on plate. Glue down the two ends with felt glue. The rest of the felt will be pressed down by strings.
