I think if you order a bridge blank from Quinn Violins, they stock a large selection of Despiau bridge blanks, and (fill out your profile) depending on where you are, they can ship Fed Ex. I got one from them and it came in a couple of days by normal shipping. You will still have to get it fitted professionally, and that could take a couple of days, depending on how busy the shop is.

You do not want a bridge made from oak by an amateur, IMO. Too much trouble, too many risks, and wasted time. You'd be better off gluing the old one back together with hide glue, or for temporary use, Elmer's Carpenter's wood glue, Titebond, or similar wood glue. Then take your time and get a real maple bridge fitted.

The heart probably has some effect on the sound as almost all details of the bridge have an effect on the sound. If your old bridge was fitted correctly, use it as a pattern.

I have seen some home made bridges from other woods, but never oak. Maple is the traditional choice with the grain running parallel to the top of the bass.

I am not a luthier, period, but I am a pro woodworker. A long-grain glue joint will be at least as strong as the surrounding wood IF the joint fits well, the appropriate glue is used, and it is clamped properly. I can't comment on what effect it would have on sound.

Gluing something (that you care about) together properly is no joke, however. Fit, clamp pressure, type of glue, gap size in the joint(s), amount of glue, and alignment are all key components. A glue up can be a one-time do-or-die affair...tough to undo a bad job. There are only a handful of things more desperate than a glue up going awry.

+1 on the respectful recommendation to get a real bridge fitted by a real pro luthier. As my old boss used to say, "O.K. we can whittle the Christ child out of a clothespin, but why would we want to?" :)

A more thorough, loving explanation is that having someone (who charges for their time), regardless of skill, make a one-off piece for the first time is likely to take longer (be more expensive) than something made by a well-respected specialist. The quality is another issue. If someone is grappling with the most basic factor, specie, then what pitfalls will they encounter regarding angles, finish, grain orientation, moisture content, growth ring density, etc.?

I am a true woodworking nerd from way back. I can make just about anything out of wood (eventually :)). That said, I buy out whatever I can, from those who make the item in question all day, every day. IMHO, to do otherwise sort of implies that their knowledge, skill, and years of experience don't have much value.

What is our time in this life worth? My basic sense is that it should be spent doing what we each do best, have a passion to do, or both. Making bridges, for me, doesn't fall into any of those categories. Just a thought...

Bass bridges you see today are the product of hundreds of years of experimenting. The heart in the middle is there for a reason...if you look at a bridge you will see that the heart cut-out is under the D and A strings and the other two cut outs are under the G and E strings. Its to help provide a more open and even sound from the bridge. There may be other reasons too but the point is a bass bridge is not just a funny-shaped piece of wood to hold the strings in the air.
Take the advice from other posters. Buy a bridge and get someone who is qualified to fit the feet properly, taper the top and check and replace the sound post if necessary.

It's not about strength, it's about not damaging the top of the bass and about the tone. Just do it that way even if you don't get it.

If you run the grain the other way, at a right angle to the bridge, you will have end grain sitting on your top. Add string tension, and it will seriously dent the spruce, immediately. While I don't know what the sound would be like, I do know that you would punch a couple of nice unfixable dents (cut grain, unsteamable) into your bass top. The feet would press in the spring wood much more than the summer wood, hence uneven foot contact.


+++++1 on don't do it.

Essentially, you are talking about a slice of end grain that is cut from a block about 6 1/2" thick...Never mind all the other issues...:)

I'm an experienced woodworker (with real live training and professional experience) and I've done a fair bit of luthier work to my basses and to my friends' basses. I'm big on do-it-yourself personally and I wouldn't be automatically discouraging to anybody. Even so, I would never decide to make a bridge as opposed to simply buying a blank. The quality of materials and the design/production expertise embodied in even the cheapest blanks are things any person working on their own would be hard-pressed to beat. Some things are way too cheap to think about building, and I think a good bridge blank is one of them. Your DIY work is cut out for you just in fitting the thing, let alone making the thing.

but if the grain is parallel is it not easyer to brake the bridge ?

If the bridge is correctly fitted, this is in fact the best way for the grain to support the force. The grain is like a stack of long flat bricks on top of your bass and the force bears down directly on top of that stack. If your previous bridge had the correct grain orientation and broke, it was because it was fitted improperly to the top, probably the wrong angle.

This is not a new question. Bridges have been cut this was for hundreds of years and for very good reasons. It reduces the likelihood of breaking, warping, and protects the soft wood of the top. It's a bit late to reinvent the wheel in this matter;- unless you want a plexiglass bridge.
