[HBR] overloading the HBR

[William Wood]

Glad to hear that fella
can’t let you fall off the edge OM  : )

Have some experience with guitar banjo and fiddle making and repair
that can be a sloooow business, but fun and rewarding for sure.  Sometime
I’ll tell you a story or two, but my basement is calling me, digging for
some parts that have been playing hide and seek with me…

I do have a lap steel about 30 percent done, carved it out of walnut and
is a one piece item.  Lots of chisel work : )  But hanging in the stair well
now of almost two years : )

73 fer now
Bill  KE9XQ
PS NEVER EVER give up as they say : )
