I'm not sure how I got that emoticon or emoji or whatever you call that thing in my post, but it was a mistake--I never use the things!

Re: Can someone walk me through speaker design? I have no idea.

I believe the preference for MDF is because it has a higher damping factor than plywood, although ply will make a fine speaker enclosure as well. As for aesthetics, I believe that's a matter of individual taste. Some might be happy with a nice coat of paint, others would prefer a fine veneer, and th...

Re: Bending Luan Plywood?

Bob's suggestion is a good one. I've bent lauan plywood to make a guitar case, so it can be done, but I think you'd have trouble with tight bends.

Re: Nut width/string spacing vs bridge string spacing

Only to folks used to/preferring the narrower nut width. It makes perfect sense to me, as I'm used to the wider necks and can't seem to play those skinny necks. I believe that Fender necks come in several different widths, though the skinny ones seem to be more common.

Re: Aging a china made zink cast bigsby

David, I believe zinc is the primary component of "pot metal". And I'd wonder why they would cast a Bigsby in magnesium, when aluminum or some formulation of "pot metal" would probably be easier to cast for this purpose.

Re: What's the best fix for a broken dovetail on a Gretsch archtop?

"Here is a 1975 Gretsch with a kind of funky neck bolt arrangement." That's not really a neck "bolt", but a wood screw that is driven through the heel and makes up for a possibly ill-fitting dovetail. Gretsch seemed to have some problems with their neck joints and took to using the screw as a "belt ...

Re: Heat bending linings

I use 3 layers of 2mm basswood, glued up around the same form as I use for laminating the sides, then kerf where necessary to fit them in. My sides aren't contoured for a domed top or back, so that's no problem. I happened upon a lot of basswood venetian blind slats that, when planed to remove the f...

Re: looking for red dot

I remember that Dan Erlewine (Stew-Mac repairman) suggested using the tip of a carmine red pencil superglued into a 1/16 inch hole in the side of a Gretsch fretboard that matched the original perfectly.

Re: Anyone Building Spinets

Although Peter Barnes' website doesn't mention plans or book, I believe if you contact him by email he can supply you with either. I bought the book from him, but had to email him to ask whether it was available from him. I don't know why he doesn't put it on his site.

Re: Thick binding in cutaway of Gibson archtop

I don't really know how they made the "filler", as I've never looked inside one. However, I have a plan for the D'Angelico New Yorker and it shows a solid piece of spruce filling the gap. I have also seen photos of an old Gretsch top removed and it had a piece of tulip poplar (judging by the green c...

Re: Thick binding in cutaway of Gibson archtop

It may have been "laziness" as suggested above, but I think that aesthetics plays a role, too. To me, the "modern" way of making cutaway archtops, where the cutaway is arched to meet the sides is not as attractive, as the cutaway looks like a funny bubble--but that's just my opinion and needn't be y...

Re: Thick binding in cutaway of Gibson archtop

Yes, I believe that the arch is made symmetrical and then the cutaway is made after. There is no "gap", but the linings are supplemented by a piece contoured to fill the gap, then the binding ledges are cut as Barry suggests, not following the arch in the cutaway, but rather in the same elevation as...

Re: Repairing a old Gibson archtop

I second David's suggestion to replace the bars' full length. You could either put a thinner neck pickup on, or use something like a filtertron that mounts to the bars rather than the Gibson style mount.

Re: Bending Iron Question

David is correct about the temperatures needed to vaporize galvanizing. If you search for "brass wool" or "bronze wool" you will find it available from a number of sources. Google (or your other preferred search engine) is helpful.

Re: Bending Iron Question

Yes, I believe your memory is correct: heating galvanized iron pipe can cause toxic fumes from the galvanizing. Stainless steel should be safe, but copper or brass scouring pads would probably conduct the heat better.
