Just seen the post - good stuff @--Jim-- Dunleavy.    

I may be embarking on a similar venture to replace the pegs on my 3/4 E-bay fiddle. It's quite old (late 1920's) and has clearly been played a LOT over its lifetime.  

Although the pegs grip, and adjust easily, the peg-box holes are either heavily worn through use (the pegs protrude pretty far on the far-side - and there is only one fine-tuner on the E) or it has been reamed out sometime in the past.   I may need over-size pegs to sort this, or even plain un-tapered blanks if I can taper them down.   There's no hurry though - the fiddle is fine as it is - I like its sound and if I even bother, it'll be a job for the autumn/winter nights anyway !
