Looks really nice. Your varnishing skills are amazing. 

I only have one criticism. The outline doesn't really read Bergonzi, if it's Carlo that you're going for.

I would not have noticed the Bergonzi purfling miters w/o you telling me about them.  They look like they belong, nice work.  I'm playing the tail cord dance now with the viola.  I'll bring it by when I'm home long enough to finish the setup.

Thanks Jim!  I'm looking forward to it.

Thanks Nick, the varnish on this one was actually a real struggle. 
I think what happened is that I burned off the mastic while heating it up and this caused it to be extra tacky and pilly. 
Honestly, it was such a mess that if I had been trying for a straight varnish I would have had to strip it and start over. 

Here's a side by side with the instrument I was working from. 
The corners definitely got elongated in the translation.  
The thing that strikes me the most about Bergonzi outlines is that the figure of 8 shape gets interrupted in the upper corners. 
The upper bout feels wide and helmet-like which makes the waist feel more narrow.

Huh. Well that looks spot on actually.  Doesn't look like his normal work, though.

I’ve been working on a Strad model for a few weeks.  The red maple I’m using seems to be pretty dense stuff. I’m having trouble getting the weight down without lowering the tap tones too much.  As with the last one, I’m planning on stringing it up in the white and making further adjustments.

I just cooked up a fresh batch of varnish today and made a point to mix in the oil at as low a temperature as possible.  So far I’m happy with the color and consistency.  We’ll see if it dries in a reasonable amount of time..

Here I’m trying to capture the dichroic (not dichomatic ;) ) effect of the varnish. The stripes look red from one angle and yellow from another.

I’m using an african wood called Mopani.  It turns well and is relatively cheap.

This was a practice piece that I turned from a boxwood branch..

I keep it around as a little sculpture.

I’m feeling better about the edgework and corners on this one.  There are a few rough spots with the purfling from not cutting the channel deep enough.  Hopefully I’ll have it strung up in the white next weekend.

the peghead shapes are a little inconsistent but I can live with that..

Sweet.  You're making me itch to get a lathe/follower setup.  I've logged a fair amount of time on a lathe but it's been years since i've used one.  My current project has me wishing I could turn my own pegs.  Great job and looking forward to seeing the fiddle all set up.

Thanks Thomas, I really enjoy working with the lathe. There was definitely a period of time when I was learning how to use the different types of tools and the mistakes were sometimes explosive.  The skew chisel is still a challenge for me but I don’t do too much spindle work.  For the most part the detail tools I’ve made for collars and pips function as scrapers.

This instrument was a speed build for me. It took about two months of weekends to get it built and set up in the white.  The varnishing is going to take a bit longer.  I just picked up the Stradivari Varnish book and there are a few things I’m rethinking. 

I’ve been experimenting with casein as a sealant. It doesn’t seem to take much to keep the end grain areas from burning plus it’s fun to make.  I’m also thinking of reintroducing solvents and trying for a leaner ratio closer to 1:4

Here’s my first experiment with something close to 1:4 varnish compared to my previous batch of 1:1.  The 1:1 looks like it’s faded a bit. I’m curious to see if the 1:4 does the same.

is that 1 part oil and 4 parts rosin?     Do you have to add a lot of thinner to get it to a usable consistency?

Yes, it has a lot of turpentine mixed in.  It's an experiment so I'm not sure how it's going to dry yet but it seems like the working time is shortened considerably.  As the turps evaporate the varnish starts to get gummy so there's really only a window of 20 seconds or so to get it how you want it. 
 It'll probably be more of an apply it and leave it scenario similar to spirit varnish application.

I’ve also been working on a 2 gallon batch of dandelion wine..!

I'm pretty sure that dandelion wine will not work as a ground.  If you send it to me I can properly dispose of it.  You might want to try making some mead, and if that doesn't work on your fiddle you can send it to me for disposal as well.

Ha, good luck procuring my secret wine recipe!

Here are a couple shots of my experimental varnish in progress.

After a coat of casein rubbed into the wood..

and after a thin coat of varnish.  I started out too thick and had to wipe it off with alcohol.  It brushes on thin and dries to the touch in about an hour.

i had some burning in the end grain areas. Next time I’ll put an extra coat of casein in these spots.

The current color looks very Amati/early Strad to my eyes.  I’m trying to decide if I should add color or see how it turns out on it’s own.
