Peter KG's Bench

[Peter K-G]

After yesterdays adventure with a series of "unlucky" incidents, I went straight to the workshop in the morning, to see how it turned out. Everything is fine, the minor uneven bending can be hidden, but I really should learn to stop when things aren't going well!

 

 

Decided to document every mistake and problems that's coming up along the way with this one.

That's smart.  I often think I make mountains out of ant hills.  On the flip side, there are probably serious mistakes I'm not even aware of.  Showing your "good" and "bad" work is a nice way to learn the difference.

Instead of making new proper clamping blocks I continued improvising

 

Shame on me!  I promise I won't do this again.

Linings on back side done, this time I extended c-bout lenghts into the corner blocks, at least a little. I always make linings "on the fly", usually from some leftovers, this time from the top wood.

 

 

[Peter K-G]

I corrected some errors that occured during ribs gluing in upper bout, by adjusting the bending of the linings.

 

[Peter K-G]

Back halves joined together. This wood is different from what I have used before, same thing with the ribs. Only toothed blade works. I primed the joints before gluing. Unfortunatly I think I might have used too thick glue for the final gluing (used a lot of glue). Clamped together tightly, put some more glue over the joint and brushed over with hot water a couple of time. Let's see tomorrow.

 

One thing hit me, maybe it would be a good way to glue the halves directly after planed with the toothed blade without scraping the joints flat?

Next time duck, so you won't get hit by these things again.

Jepp, probably not a good idea, but I wasn't that out of line:

This also confirms using a plane like a scraper in the planing ribs topic:

[Peter K-G]

As I suspected the joint is not perfect. I know the gluing is strong so I will go on with it. It looks better on the back side and deeper down. The wood is a little odd and special. It will be exciting to see how the tuning turns out.

 

 

Fortunatly I have planes nowadays

Why are you using a toothed blade on plate joints? 

[Cliff Green]

My studies suggest that the fine straitions prevent transmorgrification of the modes between bass and treble sides of the plate.

I didn't manage to get any normal plane to work on this maple! I tried all the other planes above, even rasor sharp and thin shavings as I use to, but i still chipped out in the curls. It's a new experience for me. The Wood is also well seasoned.

 

If you look at the second picture (back side) you can see that the wood is grown uneven and dense grown. it looks like maple for bridges in some places.

[Peter K-G]

Found a couple of hours to do some work today too. Someone reminded me with the last violin that we live in 2013 so I got me some power Tools. The joint is fine deeper down.

Not that it matters at this point but 553 g and 615 Hz

[Peter K-G]

Traveling... going to look for a violin shop and test some violins after meetings today. I usually do that when I visit Cities.

[Peter K-G]

Fortunately clients can't read minds as I sit in meetings and thinking about carving maple

Played some factory violins ~2,5 K€ all "softies" and very light. Didn't have my pad with my so I couldn't track the modes this time.

[Peter K-G]

I invented a new KPI (Key Performance Indicator) gram/min. 1 hour of exercise,

109 g removed -> 1,82 g/min

 

 

445 g, E string

Peter,

Can you Tell me what app you're using for mode tracking?

Thanks

(I'll PM you one of these days for the whole picture!)

[Peter K-G]

I'm using Studio Six Digital - Audiotools (FFT)

http://studiosixdigital.com/audiotools/

It's a great App with a lot of other functions besides FFT.

I have also used it as a tone generator for double checking modes and chladni patterns.

.

[Peter K-G]

Blood, sweat and g/min dramatically decreasing. Bad KPI it's logarithmic, KPI's should be linear.

 

Edges 4,2 mm

 

 

Great Wood!

Humidity 42%, 369 g, 683 Hz, clear and sharp ring

After this it will be "secret" stuff for a while
