Hi all,

I’ve purchased another fixer-upper bass. Here’s a description, a few pics, and a couple of broad, “get-started” questions. Note, a longer than usual thread.

It’s a smaller, flatback bass, with hatpeg tuners. The seller described it as Czech, although it has no markings anywhere The scale length is 39”, meaning perhaps a half-size? It has unfortunately, been stripped to a blonde-ish finish. I’ve taken the top off, and found:

1) Good stuff about the bass:

• The top has few cracks, and no deformations.
• The back is mostly solid, with only a couple of filled cracks. It has some slight warping on the lower bout
• The neck body join is secure
• The bottom and top blocks are unbroken

2) Not-good stuff about the bass:

• The neck is somewhat bowed. It is probably fixable using a carbon fibre insert.
• The fingerboard is painted maple, which I will likely replace with ebony.
• The cracks have all been “repaired” in a horrible way (see pics). At each bout, there pieces of the top have cracked and been glued back on imprecisely. These repairs were then bolstered with “cleats” that are just big pine rectangles. Arrgh!
• The ribs also have a few cracks, again glued together imprecisely, and shored up with odd bits of wood.
• The back braces have come away in spots. In some cases they have had shims glued in to “fix” things.
• In general, way too much glue was used when the bass was last put back together. Between the middle braces on the back, it almost seems like the strategy was to “flood” the area with glue (like when you’re making a backyard skating rink!). The glue seems to be clear amber, and it is dry and brittle. I might be able to scrape or chip it off (!?). Any other ideas re. glue removal?
• The bass bar is integral. Not sure I want to deal with this. As mentioned, the top is stable.

Repair strategy:

My sense is to take out all the improper old repairs, remove as much glue as possible, and re-do all of the cracks to the best of my ability. I’d like to refinish it to a darker colour when done. Also, I’m thinking of “fluting” the replacement fingerboard to give it a little more width (ie., more like an adult size). I have very small hands, and a 39” scale length might be a good fit.

I’d be happy to hear some thoughts on any of the above.

Cheers,

Paul

The top taken off. Note, there are a couple of "real" cleats mixed in. The tape at the bottom is to hold a piece of the top for later gluing.

Is that the one that was floating around on Craigslist a few weeks ago? It reminds me very much of the Czech roundback project I keep finding reasons not to work on, ha ha ha. Especially the gigantic domino cleats. Were yours stuck on with hot-glue-gun goop like mine were?

Looking forward to another of your photo essays!

Yup, I had to drive down to Batavia to buy it (not so very far from you, I think). So far I have $400 invested, plus the potential for hundreds, if not thousands, in sweat equity.

That's the one. For some reason, the landscape in that part of the state is practically littered with old basses. My is-it-a-Juzek came from an attic outside Syracuse.

I think you're looking at a few thousand in sweat equity. My project, which needs a lot of the same repairs plus a collapsed lower bout rebuild, was estimated as a $3k US job. I swallowed hard and called Metropolitan for raw materials. Good luck with it.
 
Try this link: http://s1192.photobucket.com/albums/aa338/Clearspot/

I believe it is under Czek Flatback Restoration. ( sometimes the technical stuff like posting pics can be a bit frustrating, so if it doesn't work let me know and I'll try again).

I viewed the link you noted as well as some pics from Jim Ham and, as I recall, one or two others. Each seemed to have slight variations on the placement. I measured the angle of the "propeller" and took the average for mine. I also segmented the crease brace, like Jim Ham's. The cross angle piece at the bottom is to flatten out a warped area on mine. It is made out of piano soundboard bracing ( which I use to mill my own sound posts out of... But that's another post if anyone cares to discuss)

Hope this helps
