Jointing top

I also did the jointing of my Lutz spruce top.
Having recently learnt how to read runout from a light source from Alex (Alexandru Marian an upcoming luthier, who really delved deeply into various aspects guitar making), I choose the joint face which will give less runout

Notice the light reflection graduates smoothly from L to R.
In a runout joint, you can see a side looks noticeable darker than the other side.
And when you turn another angle, the dark side light side reversed.
This is due to the grains going to different directions and thus reflect light differently from the other.

I use my #4 for shooting the jointing edge.
Ever since I fine tune my #4 and upgrade the iron, the plane was a pleasure to use.
The shavings are so fine and it's easy to do a jointing even though it's only #4.

Fine shavings from #4

Again I will look on a lighted source background to determine if the joint seam is perfect or not.
Once I am satisfied, I began to glue it using HHG.
Well since I have to act fast, I didn't have time to take pictures.

Preparing to glue

I applied the HHG to the edge, place on the jig with wax papers.
Tied in the rope, and drive in the wedge.
After gluing up I fire the dehumidifier to control the RH to 45% or so.
Well I just chuck it underneath my table workbench to better control the RH.


Joined top

I had some problem with the tear-out of of the spruce.
None of my western plane no matter how tight I adjust the plane mouth can plane the spruces properly without tear-out.
One way is to sand it level and smooth using a rough grit but that will take awfully long and it's tedious work.
So I thought of using my MJF high angle block plane and it works just right.
I manage to level the tear-out portion and sand it smooth.

My chisel collection

I was maintaining my chisel, sharpening them and coating them with a thin layer of mineral oil.
I thought it will be good to take the collection of my chisels.

Here it is my chisel collection

On the left is my Buck Brothers (from Diefenbacher) firmer chisel set (1/4", 3/8", 1/2", 5/8", 3/4", 1").
