I used inkjet machines with a remote printhead in previous jobs , printing on paper, cardboard and plastic food packaging .

The technology I used was called CIJ (continuous ink jet) , the ink and a solvent was mixed in the machine and pumped to the remote printhead ( 2-10 metres away) ,where a piezo nozzle turned the ink stream into droplets which were then electrically charged.

An electrically charged deflector plate then directed the ink droplets into text and onto the print substrate .

Any unused ink drops were deflected into a "gutter" and returned to the control unit by vaccum to be reused.

The machines were designed for continuous industrial use and even basic units were expensive to buy , €7k approx .

Linx and Videojet were the machines I used.

I have seen handheld inkjet printers used on cardboard and similar packaging and had a demo of a Reiner handheld inkjet printer which may be more suited to your application but still quite expensive.

Thanks for the interesting response everyone, I had thought of changing the master cylinder diameter but the master cylinder is fitted in a pretty awful location under the dashboard on the cab bulkhead , access is terrible.

That's why the idea of a remote servo appeals to me as there is plenty space under the cab to mount the servo unit and access to the clutch slave cylinder is fairly straightforward .

I ve been reading up on this online today and it seems to be a common modification to older land rovers which appear to suffer from heavy clutch pedals , I have discovered that there are different servo " boost" ratios 1.65. 1.9 2.3 etc. , I would guess the more boost the better in this application

Hi All,

I thought this might be a good place to ask about a query that came up in discussion with a colleague,

He has a tractor with a hydraulically operated clutch, a traditional style master cylinder to slave cylinder on the bellhousing arrangement . The issue is that the clutch pedal is very heavy and always has been, it seems to be the way with this model tractor.

This got me thinking , would a brake servo device help to reduce the pedal effort required? I remember remote brake servo kits being advertised in 1970s car magazines ,the Girling Powerstop being one unit I remember.

Does anyone have first hand experience of such devices and is there any reason why a remote add on brake servo unit wouldn't work in a hydraulic clutch application?

It looks pretty neat, let us know how it works, maybe try using lubricated air ? The mist of oil in the air might help it to run smoothly.

Hi David,

Welcome back, it's good to hear from you.

This is the second time today that a member on forums that I frequent has reappeared after an extended absence.

It must be the time of year or maybe I m spending too much time on forums!!

Looking forward to hearing more about your Myford, All the best,

Liam

I thought something like this only last week, with my phone in my pocket, I was showing an apprentice how to grind a tungsten for Tig welding. The next time I looked at Google an ad for a tungsten grinding machine pops up....

Skynet is definitely coming, I remember thinking that a few years ago when watching the Terminator show at Universal studios shortly before Universal shut it down.

Despite the show being 21 years old at that stage I thought it was never more relevant

That's fascinating.

Ian, that is interesting regarding the viton o rings. I remember hearing about potential dangers of working on equipment containing viton which had been exposed to high temperatures or fire.
