A-9s custom brackets for custom mini speedometers

Terry,

Well, shoot... that explains it... oops...

rodburner -

I came this close to emailing you sunday and asking you to
check clearances for exactly that - a knob slot (does that
sound sleazy or what) - instead, went over to lox's house and put one of the protoypes over his speedo & drew the knob position right on the plastic.

What I'm thinking about is adding is a slot and then a second 1/8" retaining ring... slide the speedo through and then rotate, just like you said, but then, rotate the second ring into place... the ring would have a raised tab to match the gap in the slot... anyway, working on it!

But, may be moot as far as Bonnevilles are concerned - as you've pointed out, the little gauges are a good height just as they are - much lower could well be too low - other issue would be speedometer cable clearance - would probably have to move the gauges further apart...

It's all in the details...

Cheers,

Not sure if anyone's still interested in this thread- it's 4 months old, but I want to make some custom brackets for a tachometer- but not the mini one. I want to keep my regular sized speedo and get a regular sized tach that matches it, then make some brackets to install the speedo and tach right over the forks, like this:

My question is does anyone know of a source for tachometers of the same size as the stock bonnie speedo?

Granitsky -

Good to read your comment - you're not alone, others have suggested some brackets that do exactly as you've pictured, suspending the gauges apart, using the fork bolts like some of the older Bonnies... agreed, it would look cool!

Couple of things to keep in mind - choices of tachs & speedos for the Bonneville besides the stockers include minis, mini-mini's, some really cool high-end stuff, and whatever you can make work... :-D .

Question - are mini-gauges out of the question for the project? They look somewhat closer
sizewise and stylistically to the gauges in the picture you posted than the stock gauges do... let me know if you'd consider going this route, I may have a couple of these brackets left...



Meanwhile, back to the fork bolt-mounted bracket concept... one puzzle that has yet to be solved... the existing fork bolts seal the forks... because of their design, I'm not sure you could hold a bracket down with the OEM fork bolts
while maintaining a seal without getting into more involved machining of the brackets... there's fine threads, spacers and O rings under there... Loxpump has suggested drilling and tapping
a small hole into the top of the existing fork bolt and running a fastener through the bracket into that hole...

Say you had the custom brackets fabricated and had solved the sealing issue/fastening method... routing of the speedo cable would need to be
worked out, as of right now the position of the headlight bracket right under the speedo looks like it might not allow the speedo cable to connect. Are you ok with rotating the speedo CCW - 30 degrees or so - to allow attachment of the speedo cable?

FYI - new "lay-flat" bracket due out soon, uses stock tach, speedo & indicators... far different from what you're searching for, but may be
worth considering, here's a pic...

BnB,

This thread posted the original Generation I mini gauge brackets, no longer in
production, having been replaced by the Generation II mini gauge brackets, which allow full seating of the gauges, including mini speedos with resesttable trip odo on the upper left side...

Hope that clears any confusion.

Please see this post for pics of Gen II mini gauge bracket prototypes:
