Re: Saddle position

I feel for you. I've fallen into just about every amateur trap there is, and then some. Here's couple of ideas in no particular order. 1: Shim the neck so the 12th fret is 3 or so mm proud of the body. If you cant hide the shim, contrast it and make it a feature 2: Lift the top and move it a few mm ...

Re: What NZ woods are these?

Puriri is a green coloured wood, which looks like the centre. However it fades to a brown shade over time, depending on how much sunlight it gets.
Rewarewa has a grain structure very similar to London plane. Silvery white wood with very wide strong orangey/red medullary rays.

Calling Taranaki/Manawatu luthiers

Does anyone know who has a decent sized resaw in the Taranaki to Palmerston North area that is willing to rip down some 2m 250 x 50 planks to 250x 6?
I've got some pohutakawa and rata planks that are just a tad to big for my 14" bandsaw.
Cheers

We have a lot of home grown exotic timbers here so they may not all be native. I am no expert but here is my best guess 1, centre rosette, puriri 2 black maire sapwood 3&7 tanekaha or kaihikatea 4 black maire heart wood 5 matai (varies from a light gold to a deep red gold) 6 tawa, possibly tairere. ...

One good thing about the lockdown

The garage that I use as a workshop has just evolved with little thought about layout. Over the years of very amateur luthiering it's degenerated into a messy crap storage area with little to no workspace. You have to climb over piles of crud just to get to the bench. As that is piled high with even...

Re: Building a Baritone Uke

Sorry Lillian, the manager looks incorruptible.

Forgive my ignorance if I have this wrong, I thought balalikas only had 3 strings and what you built is a hybrid.
A balalele maybe
It looks good though - deserves it own thread.

Re: StewMac fret blade arbor size

You could set it up in the drill press. Block of wood underneath it, clamp it down and drill it out to 20mm. The local engineering store should stock drill bits. Ask for a 1/2 inch parallel shanked, 20mm drill bit.

Re: Bellied up top

You want to stiffen up the top without removing it and Martin has mentioned a few challenges you will have to overcome. How about leaving the braces as they are, glue a strip of CF on the top beside the brace and another over the peaks of the brace. A bit unconventional, but at least it keeps the to...

Re: Twisting deflection

The calcs shown in the book are for beam deflections where the length is substansually longer than the width. Deflecting the front panel by the corners doesn't give you the correct profile to use. You'll need to cut a strip off that is on the angle you want to check. Dissclaimer: I have never used t...

Western Hemlock as brace wood

I ordered some sitka tops from Alaska but (stupidly) didn't order any brace timber. The old piano sound board i was going to use is not very well quartered, so Ive been hunting around for an alternative and came across western hemlock. From the Wood Database its not to far off sitka. Density 465 kg/...

Re: DIY plane blade query

If you want to design your own blade you'll need to use a better quality carbon steel than mild steel for reasons already mentioned. Bisalloy or gauge plate are 2 that come to mind.

The answer to the bridge thickness is on page 20-8, second to last paragraph. "Sand material off the bottom laminate to get the required curve and thickness" but not quite put in those words.

Re: Classical Bridges using CF

Cheers Martin, those are all good practical reasons, but if a CF saddle can act as well as bone it's worth a try. (My opinion only). First though, I need more experience. (I've yet to work with CF) Once I can build a 1/2 way decent guitar Ill revisit this. To get back to original topic, Richard was ...
