Re:Breva/Norge Handle Bar Risers de Oz
You can put the base plate and one riser (just) and not change anything.
I can make a base plate a bit thicker (9.2mm rather than 8.5) for you if that would be better.
At this stage I don't need final decisions, I am going to make up the pile of ally that I have. WHen I send them away to get anodised you will have to decide on colours so that will be decision time.

Re:Breva/Norge Handle Bar Risers de Oz
I'd prefer a thicker base plate if possible. I just need enough height in order to rotate my 1200 Sport bars back without the switchgear hitting the tank. Black with silver lettering for me please :woohoo:
Not being pushy or anything but do you think this is something that could be done in the next couple weeks? The riding season in New England will be coming to an end shortly. I am in for a set regardless of the timing but the sooner the better. Thanks for tackling this.

Re:Breva/Norge Handle Bar Risers de Oz
OK updated the list above.
John
You can put as many side plates as you like - the bars won't hit the tank.
Yetserday I test ran the G Code files in the new MACH 3 controller software and it threw up a heap of errors, so looks like we are going to have to re-do the code that controls the mill. I am hoping to start cutting this weekend.

Ok Third time lucky with this post - went AWOL twice now, must have hit submit at a bad moment in the forum upgrade process.
Anyway
News.... Taaaddddaaaaa
Tuesday we got the G Code to run. That's the code that makes the cutters go where they should, I am an expert in writing G Code that causes the cutter to try to machine enourmous gouges in things that shouldn't have enourmous gouges in them, so this was indeed a moment for celebration. We had been using a generic Fanuc post processor for Mastercam but it was throwing up errors, so with a bit of a re-write all was good except Mach 3 wasn't happy. Eventually found an option in the preferences for the software that was set to calculate arcs and radii in incrememental mode rather than absolute, changed it and viola - we are ready for lift off.
So what's next.
First the aluminium stock has to be stress relieved in our oven by heating up and then allowing it to cool veeeeeeeeeeeery slowly several times. This process will remove any latent stresses in the material from when it was stretched during manufacture, without doing this there is a very real possibility that the longer plate will warp when I machine half the thickness off it in the middle - something I am sure would cause swearing.
Then we will be ready to make a mess on the shed floor..
More later, gotta go to work.

Hi Mike and all!
I have sent you a pm asking for some info about those bars. I would like to have a base and four single plates for my Norge, and would like to know how much this will cost. Although my real issue with my bike is the distance between me and the bars. I would like to know if they will be closer to me apart from being higher.
Thanx in advance for your time and effort!
Greetings from Spain
Chus.

G'Day Chus, Lucky you posted as well - no PM came!
Added you to the list.
How much? No idea, but will definitely be at "mate's rates".
Position: The final position of the bars will be closer to the rider by virtue of the rake angle in the triple clamp. It's not a lot, but I certainly notice it on the Breva - my elbows have a much more confortable bent position rather than being stretched out.
Colours: spoke to the Anodisers today - colours available are Red, Gold, Blue, Black, Green and Natural. The Logo can be in any colour you like.

Ok, if there is an improvement in the final position I am definetely in for the bars. Colour would be gold for the base plate and the side plates and black for the logo. I dunno know what happened with the pm but, knowing me, I suppose I did something wrong 
Looking forward to hearing from your news soon
Cheers, Chus.

Thought I should bring the project up to date - been working on it in the shed all day today. But before that I have to say that we have had some trouble. After spending about $3500 on the Mill (a price for which I could have almost bought a new one) it is still playing up....... so today I installed a smooth stepper (look at http://www.warp9td.com/) and also found out that all the bearings in the spindle are probably shot when I found that the cutter was vibrating all over the place like a demonstrator on the counter in a sex shop.....
Anyhow we are making progress.
so here is a bit of a looksee at the process involved.
1st we set the jigging system on the table and square it up.

Then the fun starts, took all day to get this first one out and the GCode has several little problems that make running it a bit difficult, and not least is the vibration in the cutter head which will need to be attended to before doing too many more as it was making such a howling noise that I expected the thing to fall off the bench and thrash itself too pieces any moment...
Attachments
So after a full day working on it this is where we are at, I can tell you that I am no production machinist :roll:
One main plate is about half made, there are some "issues" but nothing that can't be fixed with a bit of hand filing and "adjustment"
I have to say at this point - don't hold your breath for them to be all finished, sorry to say it but better to be up front about it as there are some problems that need to be sorted out and worst of all is a definite lack of time at the moment - something to do with Xmas, a kitchen renovation, a hoped for soon PCV install and a three week bike trip to prepare for.... I'll do them as fast as I can, but be aware that there is NO obligation, if your on the list I will make one for you, but if when it is ready you no longer want it - absolutely no probs...
Here is the final result of todays effort.

What? You mean to say that you haven't dedicated all your free time and some of that which is supposed to be devoted to work completing this project? How could you??? 
It's a shame you are having such problems with the lathe - but I'm sure you'll get them sorted out sooner or later. Keep me in line - I'm looking forward to the risers.
