Is this the definition of steam punk?.. I second the notion for pictures..

OK, so long as you don't expect me to clear up my workshop! You can see the neglected dividing disc below the platform and the stepper motor and drive below that, driven off the microprocesser. 360 degrees of rotation is divided into 28,000 steps, and I can take wheels off and put them back on for extra trimming of teeth by fly-cutter with absolute accuracy. Bliss!

Mr Gazza · 06-04-2020, 12:17 PM

Yes, I think I can see how that all works. Is the dividing disc the same sort of thing as an indexing plate on a lathe?
Hats off to you for working out how to do that cunning conversion.

Yes, you've got the right idea. I thought you might have noticed it when you came round BCV, but I guess there was more-interesting stuff to look at!

interesting... how old is the base machine?

The design is ancient, but this one was made with the assistance of Myford parts in about 1988. Clockmakers had some pretty specialised production machines back to at least 1700, and their products continue to function well to this day, with a bit of help!

None Ducati this time, but with lockdown still in place I helped a mate out who needed some brake calliper pistons for a Norton Commando he is rebuilding...

I made two out of stainless steel for him as the originals were pitted quite badly... took a while to grind a tool to the correct angles and get the speed of the lathe right to get a nice finish, but I got there in the end...

They look tidy.
The hollowing out to such a large diameter must have been a bit of a challenge.

I find that slow speed and heavyish feed works best with stainless.
And a nice sharp tool with cutting oil (applied by brush on my machine).
I also try to avoid taking light skim cuts as the material tends to work harden.
Same goes for titanium, should you ever need to know.

Thanks... I agree with the heavy cuts... I hate machining stainless... its quite difficult, especially some grades! never done any titanium though...

If you do fancy a go at titanium, don't be scared of it.
Its not as bad as you might think, as long as you use very slow speeds and keep a really sharp tool with plenty of cutting oil on it.
Moderately heavy feeds too .. at least not so light as to give the tool any chance to rub.
I use ordinary HSS tools with no problem, but they must be sharp.

Been a while since I updated....early May, lockdown continues, still can’t ride, it’s very frustrating to have bikes on the drive and not ride them!!

done a few more jobs like programme the ignition advance to get a steady tick over, and importantly retard the ignition at cranking speed to give the starter motor an easier time.

Also balanced the carbs. for years I used a mercury gauge for this but a mate borrowed them and broke it! so I bought a set of gauges, but noticed I could get it closer by ear! so I checked the gauges by connecting them to a single vacuum source and found they were all reading differently! hence the single gauge with 5 valves. the 5th valve provides damping to the gauge. I have found you can get a perfect tick over with this method.

lets hope we can ride soon!

Great photos Tony, see you are getting into the spirit of posting,just the one Wheely bin

Nice to have a V6 on the drive!

I do like that orange with the grey/silver - puts me in mind of Neil Hodgson's GSE Ducati (and Laverda Jotas!).

Yes, I have always liked the orange and silver... its becoming a signature colour scheme

I had a Jota for almost 30 years! I did the Suzuki a few years ago...

the car is not the V6 model...its an SLK 55 AMG with the 5.4 V8 engine

with all that power in a small car its epic

Luddite · 10-05-2020, 02:49 PM

I like those!

I hadn't even noticed the car - the V6 I was referring to was actually the two Ducatis and the V-Rod! (A V6 in instalments if you like.)
