Arch top carving
Hi I'm building my first Benedetto arch top and am finished rough carving the bunya pine top with finger planes. I've now moved to card scrapers but find they really fur up and chip rather than nice smooth shavings. Is this just a case of (scrapers are no good on soft wood)? Should I go straight to ...

Re: Walnut bend
Thanks for all the replies- some interesting suggestions which I will try. 1/ Use an iron for the sharp shoulders 2/ try fabric softener 3/ Bend the outside curves first, then the waist I have one piece to practice on then my last 2 sides of walnut. I also feel that we (at my club) tend to bend the ...

1.8mm as per TG
But I hear what you say and I'm thinking I'll start on an iron where you can get a 'feel'
Ken Parker does a similar thing in his archtop vids.
Cranking down on a bender doesn't provide much feedback.

Walnut bend
Hi So this is the first time I tried walnut (straight grained) and for supposedly easy bend -it didn't work. The first sandwich was spritz water, paper, foil heat blanket and iron strap. Has worked well before. Heat blanket to 176 deg/off then start clamping. Heat OFF. Clamp waist then roll sides. C...

Acoustic side height calculation
Hi, Does anyone have a tip on calculating side height contour for various back radiuses? I have seen a spreadsheet (Dooling guitars) which is pretty tedious. Or is it common practice to approximate and then scribe the sides while the braced back is in the radius dish and fine tune with a block plane...

Archtop Spanish Heel
Hi I am working on my first Benedetto style 17" carved archtop. Is it worth looking at a Spanish Heel neck/body join? They work really well in flat top designs to get a nice join if mortice and tenon is too challenging. Or is the neck angle too steep for this type of construction? Rod or anyone? che...

I found some 60mm Bunya and Qld maple at a reasonable price so I'll go with your plan A.
That should get me going!

Re: Archtop Back and sides
Or if you can tilt your bandsaw to cut into two wedges about 30mm-10mm?
Am I reading this correctly?
If so, you wouldn't need as thick a billet.
A challenging cut though

Do you use Luthiers Merc for the maple?
Carpathian?

Archtop Back and sides
Hi
I'm starting a carved Benedetto style archtop and intend getting some spruce top tonewood from a Canadian supplier.
Back and sides are traditionally curly maple but that is prohibitively expensive.
Any comments on using blackwood, Qld silver ash or similar local hardwoods?
Thanks in advance

Mirotone 3220 buffing
Hi,
What is the preferred cutting compond after 1000 grit sanding to polish Mirotone 3220?
The books and others seem to recommend offshore products.
I assume car detailing compounds aren't suitable because they chemically soften the 3220?
Comments much appreciated

Hi Thanks for the reply, I know pro luthiers (40+ years in the trade) who have been using Mirotone exclusively on acoustics and electrics and who haven't recently mentioned issues like you describe. I'm currently putting 3220 on an archtop build over a Botecote fill layer. Probably not necessary sin...

Re: Nitro finish
Hi thanks for the reply,
My rep over East pointed me back to 3220!!
For info- did you grain fill the acoustics or just shoot the coats and cut?
Gravity gun?

Nitro finish
Hi
I see references on this site to Mirotone 3220 as a topcoat for guitars.
Has anyone used the Mirolac 3150 Nitrocellulose?
I'm assuming it serves as a traditional nitro finish for purists who want to avoid the poly finishes.
Any comments appreciated

Archtop Truss Rod
Hi, For the archtop builders- do you run your truss rod all the way through the neck extension ie the length of the fingerboard? Or stop at the neck join (14th fret)? The typical acoustic 2 way truss rods are 100mm too long and I can think of all sorts of reasons to not have up/down pressure on the ...

Re: ES 330 style fully hollow
Hi Rod, That's a pretty robust looking build for a 335. As I'm sure you already know- the Gretsch Streamliner (current semi) and Gibson ES 175 don't use the transverse brace up near the neck HB cavity. But Jim English swears by it in his book to avoid a potential buckle. Did you carve the back as we...

Re: Florentine tip binding
Many thanks, That's all good info and great detail. I did wonder about 'knocking the glued on option off" but then- you can always glue it back on or cut a new one, unless it tore out some wood as well. I like your option- I might need to practise on scrap tho' to get those beautiful clean lines. Th...
