Are you going to copy the low arching? You can just answer me when you get there.
Thanks for sharing and 'make a mess!' |
Actually, that's a very interesting question. One I wouldn't hesitate to ask...
What I intend to do, is to follow, as faithfully as possible - the long arch.
Then, I'm plotting some very simple curtate cycloids for the cross arching(s).
I'm more interested in what modern methodology works best, as I know that copying "exactly" what exists from the past, that's on the poster, will result in the usual. I'll tell you that I'm not on top of things any more like I used to think I was (Since, well, you know...) but I'm still experimenting with what works best today and I believe that this is a possible arch methodology that will work, so, we'll see. (And, I mean that it will most likely work better than what I usually do today - the Craig Tucker arch, that is.)
If I can get the top thicknessing, and the edge work, and the back arch, and the back thicknessing right, and the back edgework, and the rib heights correct - well, who the h e double heck knows?
I'll be posting it all so, let's see . All amateurs (of which, I claim a solid membership) beware.

Ok, I've been messing around posting here, and everywhere else I can think of, and have become tired of moving my "writing mouth" so I'm going to concentrate, once again, on being in the shop and making something vaguely shaped like a violin.
Posting on the internet can, if you let it, dominate your free time - of which (free time that is) I must once again devote to the act of making and get away from the "talking", (well, writing actually) it's interesting and entertaining but I believe that it can dominate one if one isn't careful. ("one" of course, being me.)
So for this violin I have cut out a wooden mold pattern based on the Messiah poster. How much closer can an individual get to making something perhaps like Strad? Well, I don't know - but this is close enough for me.
I'll use the rib measurements given for his violins of that period, and the tapering at the top of the rib assembly, common to his violins of that period.
But as far as the arching goes - well I'm going to completely ignore what he may have done, and use cross arching derived from cycloids and thickness-ing that I believe is proper for Sitka Spruce and Bigleaf Maple...
I'll cut out the block cutouts for this form, and post a photo of it, (it being the form or mold) either with or without the blocks glued in (which I have already cut the raw Spruce for - see a bit before this post) So, here we go again.
Photo(s) to follow.

Ha.... You reminded me of my youth when I could have played perfect tennis and made a fortune, if I could only get past my 2 trouble spots...... the serve and the return! 
Keep those photos coming, Ct... they do inspire.
Cheers!... Mat |

Well, many of you probably know I have been re-establishing myself elsewhere for a while.
But the fact is, that I am here to stay, as always, and will return to this thread and others - again, in my usual el grande boca, style...
As, I like to make violins. And that's about it.

In an interesting development, I have discovered that my neck/scroll template - which I had copied from a fairly well established source - is not really what I look for in a finished scroll.
It took quite a while for me to figure out what the problem was, and, well, you can see what it took to find out exactly what the "very small" in some ways, problem was
Essentially, the wind on the template wasn't dwindling in size exactly evenly, which was throwing my attempts to get an even scroll carved correctly. I'm finding that I have to draw some aspects of the the spiral in, myself.
And now I will go over my Strad posters, and look at the scroll/neck drawings on the back of the posters, and see what I want to use to make a new template.
Perhaps one of the drawings in the Sacconi book will work for me?
This ought to be interesting. I have also gotten some interesting information about making the separate wingdings an appropriate and even width, another weakness in my former, and present scroll attempts.
Jeeze the further I get into this the more I realize that I need to improve - essentially everything, when it gets down to the real details
Sheesh!

So where's the errorous template from, and what don't you like about it?
I make my templates by cutting out and perforating photos after I reinforce them with packing tape or multiple layers of shellac, so any picture anywhere is fair game.

Several of your flickr pics have disappeared. Is it just me?

Oops sorry, I have gone to flickr and honed some photos out without thinking about how they might be added on to posts here.
Ok - I'm a bit new at this, in a way, and this has never happened before - so now I know.
Sorry about that - I'll try looking to replace the ones that are gone.

I looked back, and I think they may be talking about some photos from my posts that have disappeared...
My bad.

It's from either one of two authors, and from many years ago. I don't really want to say where I got my original template from, because one of the people is still alive and out there. And I'm not positive, really - that the mistake wasn't mine in copying the thing incorrectly.
But my scroll has a curl that is uneven in that the width of the turn, it is not tapering correctly. Perhaps the original mistake is mine and not the author of the template drawing?
The fact is, either way, that I want a scroll with an even and continually tapering profile - perhaps it is just that I am looking at what I really want to make now, that is driving me towards changing the template I have been using all these years.
Using one template only, for ten or fifteen years, was a bad idea anyway.

| Ct, have you looked at Kevin Kelly's YouTube videos? Google ' drawing a Cremonese scroll I '. It looks like a very regular tapering volute. |

If it's a Strad scroll, it probably shouldn't taper evenly. If that's what you like to see, Andrea Amati did it beautifully. Do a google image search for Andrea Amati scroll and you'll turn up quite a few. Print one out to 105mm long, and use it as your template.

Ahhh.
Now I am seeing a bit more than I have seen in the past, as far as comprehending the FULL design aspect or aspects of what I am doing, or what I'm trying to accomplish.
And I'll be blunt here, after my recent medical problems, I'm probably looking at life with a much different and perhaps keener eye than I have in the past. The reason is, that I want to make something that will rise above the workmanship and craftsmanship (ha ha!) I have accomplished thus far with violin work ...
Thankfully, for me, it seems there is no end to the details I need to encompass and incorporate.
Yes, I have to say that I do like the symmetry present in many of the Amati scrolls I have looked up and scrutinized.
Amazing.
Life is interesting in the many surprise turns that it can take, with regard to the many tiny tiny (but huge) things that can dictate our behavior.

Gosh darn it Don...
Once I got started watching the various videos there, I couldn't stop.
The amount of information presented by very real, very intelligent people, is amazing and almost unbelievable.
Really, thanks for the heads up on this guy's videos. They're great.
