I started soldering the 4th valve circuit last night. Next will be to make a crook by cutting one in half and using tubing to get it the width I need for the lower slide.

Little by little, I'm moving along. I got a joint or two soldered, but I also got a crook cut in half and ready to start measuring, parallel-ing, and soldering that lower slide for the 4th valve circuit. A few more braces here and there and I think the valve section will be complete!

Image

As I looked over my upper circuit, I think I need to add another brace. I think I'll move the existing brace closer to the crook and add a second one closer to the valve port, as marked by the poorly drawn red braces in the photo below:

What do you think?

Last night I had the itch to work and my wife was kind enough to let me do so! I got the whole 4th circuit soldered on minus three braces that still need to be cut, fitted, and soldered. It feels really good to have it this far along though!

After I get this all squared away and cleaned up, it will be back to finishing the body work (still some dents, get the bow guards back on, etc.). I feel some momentum here folks!

I got the bracing all soldered in last night. I'll post some pictures when I get it all cleaned up. That should be it for the valve section (minus when I need to add the thumb ring and linkage, wherever that ends up).

HEY!!!!!!!!!!!

Just imagine...……… Could there be a 4 or 5 valve Martin helicon coming?

This has been a very interesting saga. It looks like you have really developed your skills to a high level. Could be a pleasurable and profitable sideline business for you in the future.

Thanks Ken, good to hear from you!

I have a friend who also suggested I do this on the side for money, but for now, having it for a hobby is good enough for me. :)

In regards to the helicon, I actually thought that if for some reason this project turns out to be a bust (which I doubt, but you never know), I'd have an Eb valvset all made up that I could put on the helicon!

As promised, here are the pictures of the 4th circuit all braced up and cleaned up!

Image

Image

Image

I can still clean this up a little more and give it a bath to get all the crud and particles that have likely found their way into the tubing and casings. After this it's back to the body work.

Haha, that's like us and our home renovation projects...we get it to where it's functional, then say "eh, that's good enough, we need to get going on XYZ now..."

I haven't update this in a while, so here's a little bit of what's been going on. I sent the bugle, braces, etc. (anything silver) down to KC to have the silver stripped off by a plating company there. The silver wasn't very good looking anyway, and as much as I love the look of a "half and half" horn, I decided to go all raw brass on this one. I'm also having some work done to the body that I don't have the tools or know-how to do on my own. I should have that back by May 9th if all goes as planned.

In the meantime, I've been picking over the valve section so that it will be ready to go. I've been taking more time cleaning up solder joints on this project to make it look a little less "homemade" than my other projects. Here are some shots of the upper and lower crooks of the first valve circuit:

Image

Image

I also got some synthetic washers from J.L. Smith and got the valves aligned. I also polished up the valveset for a few "glamour shots."

Image

Image

Image

I also added a Jupiter/Getzen version of an Amado water key. I like them because they're small, I like how they look, and they only require one spot of soldering. I drilled the hole out to 1/8" and had to reshape the curve to fit the tubing using a Dremel tool.

Image

I will start a separate thread asking for advice on assembling the bugle, since that's what I'll be doing next after I get it back from KC! Thanks for looking!

Small update: The original horn had a smaller shank receiver on it:

Image

I plan on replacing it with another vintage King receiver that I had in my drawer. It didn't look quite as bad as the one above (I forgot to take a "before" picture), but it still had the silver coming off, old solder, etc. Today I cleaned it up by carefully sanding off the remaining the silver (and the solder spots), cleaning, buffing, and polishing until it now looks like this:

Image

Small thing, but I like that it will still have a vintage King receiver on it!

That is all.

My family and I took a quick trip down to KC to pick up the parts I had some work done on (stripping the old silver and putting the bow caps and wire back on).

Here they are after a bath:
Image

Starting to mock up the layout:
Image

Mocking up the layout some more:
Image

Image

Image

One issue was to make sure I could get the 4th valve bottom cap off. The bows are narrow, so there's not a lot of space to move things around, but I should be able to get the cap off if I orient things like I've got pictured.

Image

I need to decide what to do for the finish. I'm leaning towards having a "scotch-brite" finish on the bows and leaving the valveset as-is. The brass alloys appear to be quite different, so I don't think there's much hope of getting the brass to match in any way without silver plating the whole thing (not gonna happen). It's already a frankentuba, so I'm not too worried about. I just need to exercise some patience and get the bows finished up before I get too anxious about soldering it all together!

I've been working on getting the bugle assembled. I decided to just polish the bugle and not worry too much about a scotch brite or any other finish. The horn was satin silver, and being 102 years old, there are some parts that are worn perfectly smooth, and others that still have the satin finish.

Here are all the bugle parts after a polish:
Image

After I polished them, I dry fit everything together and laid out the valveset just to see what this might look like. I really like the proportions on this horn.
Image

I began soldering the bugle together:
Image

I took my time to solder carefully and cleaned up after myself as I went along. I was very pleased with how clean I was able to get the solder joints:
Image

This brace was missing, so I had to cut down a brace from another part of the horn that wasn't going to be used. Cutting it to fit, reshaping the feet, etc. took quite a while, but I'm happy with the result:
Image

Another brace shot:
Image

More bugle soldering:
Image

This was a Holton brace and I cut the tips off of the diamond to fit on the ferrule I added to turn the dogleg the other way:
Image

Here is the bugle all soldered together. I am most proud of the fact that I only had to use wire in one place to hold a brace down (the bell to top bow brace) to keep it from slipping off. Every other part fit together so nicely it just stayed put while I soldered it all together.
Image

Next up will be getting the main tuning slide legs parallel and cut to length to fit, though I might do a hose test to see what length I'll need before cutting any tubing (attach a hose to the end of the dogleg the approximate length of the leadpipe+valveset+MTS). That will also let me hear the tuba for the first time in months! Stay tuned! I'm hoping to have this buttoned up in a few more weeks (especially now that school is out)!

Hello again! I'm getting down to the last few things. I'm hoping to have this together enough to play on it by the weekend.

Here, I was checking the position of the leadpipe (from the 12J I got the valveset from). I was thinking about bending a new one, but I think this one will work.

Image

Image

Image

Here is a mockup after I got the main slide put together for it:

Image

The position of the 5th valve was causing me trouble (it was right under the lower 1st valve slide, so I couldn't pull it, I didn't really want to redo the 1st valve circuit or move the whole valveset up on the horn), so I got the parts from Conn-Selmer to make it removeable!

Image

Image

Here's the back of the horn along with a really rough drawing of my planned circuit. I've got the tubing to do it, but won't build it until after the valveset and everything is soldered on. Linkage will be last.

Image

Image

Lots of little things to do, but I'm getting there!
