So endeth the day. It was a good day and having confronted the demon quilt I can now work on with confidence. There will still be those technical problems but I’m pretty sure I have a good handle on them now.

p.s. I also cut out the bass body and thicknessed it but forgot to take a picture. Use your imagination.

Good evening WineLovingTwin,
We have opened a bottle of Corbieres and it is rather nice! We both still have colds and can’t taste a lot but we are going to enjoy it.
I got a good bit done today. Trussrods fitted and carbon fibre inserts in the bass neck. The through neck has been hacked again to remove the wood where the overlay will fit and the overlay has been thicknessed and jointed. The fiddleback ‘wings ‘ have been prepared and a veneer of mahogany added to the jointing edge. Looking good.
And we have finished the Corbieres now. Still have the heavy colds but who cares?
I’ll probably glue the wings on tomorrow.

Strange day. This morning I helped The Lovely Syra dismantle the Castlegregory Carnival Art and Craft exhibition for an hour and then we had visitors from Germany who stayed until lunchtime. They were Joachim and his wife who are on a tour of Ireland. He has bought two of my instruments in the past and has an idea for a new acoustic so I was happy to spend time with him.
After lunch I did some trimming to the through neck (more waste wood!) then dimensioned the wings and glued them on. This is quicker to describe than to do! It’s starting to look more like a guitar now. I then levelled the bass neck ready to make the neck joint. But I can’t go ahead with this until I know the dimensions of the bridge. I was promised that the drawings would be emailed to me last week but of course they were not. I emailed them early this morning to remind them but,until now, They have not responded. It’s annoying.
So just two pics.

A nice technical day which I enjoyed. Loads more expensive firewood created which we will be grateful for next winter.

https://lh5.googleusercontent.com/-j...-+trimcore.jpg

Citaat:

The joining surfaces between the core and the overlay had to be made perfect and this is done slowly with a hand plane and lost of checking with a straight edge. Satisfying when done right.

To fit the overlay to the core the neck end has to be trimmed….

...and a straight tenon created with the router.

The mortice is cut into the overlay. This has to be exact to keep the strength around the heel area on the finished instrument.

To get this perfect there is a lot of trimming with a chisel. Not only does the joint have to be perfect but the overlay has to line up with the body centre so it takes a while.

I then created some even more expensive waste.

And glued the overlay to the core. I used three screws to hold the overlay in the correct position while I put the clamps on. The two nearest the neck are inside of the pickup area and the one in the middle (not visible in the pic) is where the trem will go so the screw holes will not be visible on the finished instrument (unless I have made a terrible cock-up!)

I called Hipshot in NewYork and got them to email me the correct drawings for the bass bridge which was a good result.

Oorspronkelijk geplaatst door MisterE

Ik had mijn e-mail naar Chris begonnen met; "I have a plan, and it involves wood"
Dit deed Chris denken aan een scene uit Monty Python & The Holy Grail waarin Bedemir zijn plan uitlegt voor het bouwen van een houten konijn en dat hij, Galahad en Lancelot vervolgens uit het konijn klimmen...
(Chris & ik zijn beide grote Monty Python fans)

Zo kwam het dat we besloten om de gitaar Bedemir en de bas Galahad te noemen.

---

Erg leuk om te zien allemaal! :ok: Ben erg benieuwd naar het eindresultaat...

Maar als rechtgeaarde mede-Monty-Python-fan, die van de week toevallig opnieuw Mony Python & The Holy Grail heeft gezien, moet ik wel opmerken dat het citaat uit de film niet verder ging dan "I have a plan" (zonder enige vermelding van hout), en dat het plan werd geopperd door Sir Bedevere. Bedemir mogelijk als gedachtensprong vanuit Boromir, maar die kwam uit Lord Of The Rings.

Ni!

I stand corrected Sir Knight :p

Voor de volledigheid.
In mijn conversatie met Chris had ik geschreven : "I have a plan"
Hij had teruggemaild met de vraag: "Is it a cunning plan" waarbij hij refereerde naar Blackadder
Waarop ik antwoorde : "No it's a plan involving wood" doelend op het plan van Bedevere om een houten konijn te bouwen

Vandaar.
ik had me de scene opgezocht waarin dit voorkwam en was op website terecht gekomen waar de volledige script op stond:

http://www.sacred-texts.com/neu/mphg/mphg.htm

Hier zul je zien dat Tery Jone's personage Bedemir genoemd wordt.
Vandaar mijn dwaling.

Ecky-ecky-ecky-ecky-pikang-zoom-boing-....

Nog heel wat info ontvangen.
Ik zal dit opsplitsen.

Good evening HairyTwin,
Before that I made a copy template that I fitted onto the rough body to define the final shape. Naturally I forgot to take a picture of the next stage where I used the template to guide a router around the body to remove excess wood. Then I sanded the body edges to the exact shape. I then did a final layout for the pickups and trem positions. I have adjusted pickup position to strat style as the original Jackson template is for 24 frets. Ignore any blue ink marks on the overlay which are just rough guides from many steps ago. What you see now is the final and exact shape. I think the next thing I should do to the guitar is make the fingerboard to ensure that everything lines up. But tomorrow I will work on the bass so it catches up with the guitar.

With a normal through neck with a thinner overlay there is a lot of the neck going under the overlay. In this case with a thick overlay there is much less which is why it was so important to get the overlay to neck joint as perfect as possible yesterday. And it is very good. I think I will put two dowels through the outside of the joint to further lock the overlay and neck together and transfer the pull of the strings through the two components (neck and overlay). A pic when I’ve done this will explain all. I’m thinking out loud which is a sign of madness so I’ll stop.

Good evening RedWineTwin,
First, and a day late, here is the copy template for the body that I forgot to take a picture of yesterday. I couldn’t use the master template as I need to allow space for the neck end so I made a copy and mutilated it! This was screwed onto the body top to guide the router.

Also here are the dowels I talked about last night and I fitted today. They help lock the top to the through neck.

Now the bass. This going to be a bit detailed because I want to use this for the Tech Bit in the next newsletter. So, if you are bored, I’m sorry.
This is how I make the mortice and tenon joint for my fixed neck instruments.
First I cut the mortice in the body using a router with a template and guide ring.

---

https://lh3.googleusercontent.com/-p...ertemplate.jpg

Citaat:

---

The template is aligned with the body and then raised to get the correct neck to body angle. You can see the calculations I did to get this angle written in pencil on the body top!

---

https://lh6.googleusercontent.com/-f...kneckangle.jpg

Citaat:

---

A router works by cutting away wood with a rotating cutter. The guide ring around the cutter follows the template.

---

https://lh6.googleusercontent.com/-G...erandguide.jpg

Citaat:

---

The router is set to a final depth of 26mm and the mortice cut in a series of shallow cuts.

Nice clean job.

https://lh4.googleusercontent.com/-m...+-+mortice.jpg

Citaat:

Now to cut the mortice on the neck. Both mortice and tenon are offset 3.5mm to the bass side which allows for an asymmetrical final carving of the heel which gives better access than a symmetrical one. The neck angle is transferred to the sides of the tenon and these are cut to the correct depth using the radial arm saw.

Cutting lines are marked and cut oversize on the band saw. Why oversize? Because it is easier to make the tenon smaller to fit the mortice than to make it bigger if I cut it undersize!

With a bit of trimming the tenon is made to fit the mortice.
