However, what would you recommended for deburring the end of such a small pipe diameter?

A small twist drill, a fine small file and Scotchbrite

1.5 mm diameter no doubt AND a file AND Scotchbrite.

Belt and braces. It'll take me all day to do one pipe...

Afternoon all, Roger, Jim probably knows more about hydro-pneumatic Citroens than I do, so feel free to take Jim up on his very kind offer of advice. Roger already knows this, but the tool has had a mini clean-up:

and is now winging it's way to him, so currently unavailable.

[MattBLancs]

I appreciate the detailed run through - thank you.

Apologies for my ignorance on imperial stuff - grade 5 is that a high tensile grade?

If I come across any UNC stuff I'll bear it in mind (my Grandad's garage is a treasure trove of all sorts, so potential source there perhaps.)

[Jay-Bruce]

Yankee grade 5 is about metric 8.8, so they are reasonably robust.

Ah, ok. Not high tensile (10.2) but not mash potato (5.6)

Can't make any promises but if I do lay my hands on some I'll shout up. I do have some UNC taps and dies so should be able to confirm what I stumble upon in there easily enough. Or for that matter easily make some replacements with the die.

[Jay-Bruce]

And not cheese like the 4.4 bolts B&Q sell. Don't worry about procuring replacement bolts, they can be gotten off of eBay, or from local suppliers up here, the main thing is that if anyone using this tool loses the bolts, they're snookered as it's 99% they won't have a suitable bolt in their garage/shed/workshop/toolbox. I also made it clear that they are UNC so that if anyone does borrow the tool and needs to replace the bolts, they don't try and force a m6 in there and mash the threads.

Oh Jim most definitely will. I was referring to care of your tool which is of utmost importance.

Thanks for sorting this today and your time.

Great chatting with you.

Wow 4.4 that's low. I image they're in little teeny packets of 2 or 3 for a bargain £3.99 too!

Don't worry, wasn't rushing out to buy some, just might be some going spare in the garage clear out. Good point about an M6 smushed into the hole though!

Seeing this tool in detail got my imagination wandering, as to the potential to create one of these.

Someone has done similar:
http://www.schaalbouw.nl/citroen/flaring.htm

But that lacks the refinement of the threaded tubular bolt which creates the pressure to form the flare on Jay's tool.

If I were to make one like Jay's, I think a couple more holes drilled and a couple of smooth unthreaded pins between the two halves would be a good upgrade, that way the two half threads would more easily be aligned.

It did tickle me a little that Jay's tool is made up of all imperial dimensions, of a piece of inch bar etc, to then be used on a completely metric Citroen!
I suppose if you were to have those UNC threads mangled, drilling out and tapping at M7 would be a nice Citroen appropriate way forward!

I considered making one when peter306 posted that link.

The imperial measurements are because the die standards are English (typically 1” x 1.75” - approx 25.4 x 44.5). I think this is because England used to be the world leader in tooling and therefore we set the standards.

Hi Matt, just a FYI, M7 is an obscure, almost propriatery thread, the logical "upgrade" would be M8. I didn't make the tool, I bought it, and a small fortune of other bits from Pleiades ~20 years ago, and I believe Martin still sells them. I personally think that as long as Martin @ Pleaides is selling these tools, there's no point "reinventing the wheel" The only other thing I'd be tempted to do to the tool would be to drill and tap a hole into the back of one of the die blocks, to enable me to screw a handle on there for on vehicle work, making it something more akin to this sort of thing:

Sorry Jay, I should have stuck another in an appropriate place - I'm aware of the funny look you get asking for M7 bolt pretty much anywhere other than PSA and I believe old Vespa use them??

Was meant tongue in cheek that the Citroen specific tool should be fitted with "Citroen specific" M7

A handle in the side does look a good upgrade.

Was thinking about making as thought I had read they'd given up selling these

Hello all,
when i spoke to Pleaides last week I did mention about buying this tool, seems they stopped making them some time ago so it's make your own or modify. an existing tool.

I wonder how many people would actually put their money down if asked?

Heat treatment of tooling steel isn’t cheap if you want a really good quality dies with great longevity.

And how far do you go? This handle idea is all well and good but personally I cannot really see a valid use for using the tool in-situ on a car. It’s not as if you can achieve anything other than a pipe end where it’s needed.

Compression fittings should only be used in an emergency on braking systems apparently so ‘cutting and shutting’ is a no-no.

Maybe there is some mileage in having in-line connectors tapped for M8 say 50mm long so you can cut a piece of failed pipe out (26mm) and replace with a union with two flares ans two rubber seals.

Perhaps I am missing something fundamental.
