Mandobird information

Recommended Posts

Greetings

 

need one general information about mandobird since I'm trying to build similar electric mandolin for myself in my little workshop.This is actually 1st instrument I'm trying to build.

 

I need to calculate length of the ''red line'' from picture.length of the most narrow sides.

without that information I'm not able to make full sized drawing of my future explorer based handcrafted mandolin.

 

 

many thanks. Pepy

Warning! Math Solutions ahead

You can pull an old carpentry blue print trick...scale it from top of head stock to bottom of the body, seems you know that length. Make it into inches or millimeters or what ever you want, then just measure acrossed your red line. maybe take some grafting paper and lay it over the picture. easy to scale stuff out if you have one known measurement.

well I dont want to scale explorer down because I'm not sure how much.

 

 

that's why I took explorer basic body draw,scaled down to A4. and then I've picked several stationary points on the edge

and counted their distances and angles.

 

then I've noticed that distance between 2 most narrow points(marked on picture) on my A4 scaled model is 650mm

 

so If someone gives me true distance ''X'' (as on original mandobird instrument) I'd be able to draw full sized scheme

 

 

because

 

X / 650 would give me a coefficient I'd use to multiply already counted distances but keeping angles the same.

 

 

 

 

 

 

@Captmidnight

 

unfortunately I dont have whole explorer scheme,only body without neck but I got your point.you play on point that I can find scale length,body length ect

 

I'll do that only if none gives me the info I need.cmon guys there must be some mandobird owner here.

I've printed out this photo

 

mandobirdpq5.jpg

 

on the paper- approx

 

Red line = 4,25cm , Yellow line = 1,87cm

 

if

 

1,87cm x K =2,404cm --> K =1,28556

 

Red Line(4,25) / Yellow line(1,87) x K = coefficient

 

 

 

so

 

4,25/1,87 x 1,28556 = 2,9217272

 

 

Coefficient = 2,9217272

 

 

 

red line distance on my explorer scheme on the paper is 6,5 cm after multiplying with coefficient gives that

 

red line in real life is around 18,9912268 cm

 

I think I'm on the right way.What do you say guys?

Red line = 4,25cm , Yellow line = 1,87cm

 

if

 

1,87cm x K =6,106cm --> K =3,26524

 

Red Line(4,25) / Yellow line(1,87) x K = coefficient

 

so

 

4,25/1,87 x 3,26524 = coefficient

 

 

 

Coefficient = 7,421

 

 

 

way too big.this would make my body even bigger than original explorer guitar.

 

most narrow part would be 48,23cm?wtf

 

 

 

I'll try to make a scheme using old 18,99cm

He's just measured it - 160mm exactly.

 

Or do you need it in inches?

 

thanks alot

.I don't need inches.I'm from Europe btw, we use cm and mm.

 

I'll do some real size scheme next 2 days and post picture of it later here.
