I've just sent a message to Renault UK, asking two simple questions:

- Does my edition of the Kangoo have this Cabin Filter?

- If so, where, please, and is it something I can replace myself?

Actually being able to open their web-site was a pain in itself as I had to up-date my Goggle / Firefox / Mozilla browser (who owns which there?). take care to turn off all the tracking software to at least limit the so-called "personalized [sic] advertisements".

I await their reply with interest, and would not be surprised if the company refuses to answer but Issues A Statement along the lines of "Renault advise consulting one of our Approved Dealers for all servicing".

My 4 axis rotary table 2 morse taper i have never been happy with ever
since i made it a long time ago it runs true enough close to the nose
but was obviously off further in as the run out increased away from
the nose.As i have had the table apart for some modifications to adjust
the step count i have taken the opportunity to regrind the morse taper.

Seen here in the photo using the cylindrical grinder the rotary table is
mounted on the magnetic chuck and set over to the required angle.At the
back of the table there is a thread to push out the morse taper arbor
and this provided a fixing for a temporary pulley to drive .The grinding
work head provides the drive via a heat joined belt.
The first attempt was not too successful as the grinding spindle was
too long and thin so i made a new thicker spindle tapered like a
morse taper and set the grinding head at an angle so the spindle
entered with some clearance.

As with any grinding job the setting up can take quite a long time in
comparison to the actual grinding.
The end result shows zero runout at the nose and about 2 tenths
at the end of the test bar about 5 1/2 inches out ,happy with that.

Reading up on the current practice on grinding spindle arbors they
seem to be made these days from tungsten carbide ,they seem to
be listed as POA which i guess means they are not cheap.
It's a different world out there ,doubt it much it would fit anyway
with my home made kit.

Still have another one to do later in the week .

Up to my armpits in work today - shielding but still working online every weekday.

However found time to fit the backplate and make and fit some studs to the 100mm 4 jaw self centreing chuck that arrived yesterday for the SC3. Now waiting for the Loctite to go off and doing some more work type work. I'll try the chuck out this evening.

Why the 4 jaw SC?

I have not yet needed to go beyond the capacity of the standard 80mm chuck for holding round stuff, but the small hole through the middle has been annoying me - hence the larger chuck. I really don't know why this is so because the previous Drummond Roundbed has no hole through the spindle at all!

Anyway decided on the 4 jaw self centring as hex larger than 15mm in long lengths is unlikely to be an issue whilst round might and the ability to hold square easily (only as accurately as any sc chuck, I know) could be useful.

I'm probaby wrong in my assumptions!

snip/ I reckon modern car designers have a priority list: 1 style and luxury, 2 performance, 3 efficiency, ... (n) annual servicing to the specifications they set, last. /snip

Nigel, your nbr 3 should move to nbr 1. All motor mfrs have to meet an EU economy/CO2 target, averaged across the whole range of vehicles they make. If they don't meet that target, they have to pay a financial penalty levied on every vehicle they produce. Still leaves user-friendliness in last place.

John, could you explain your setup in more detail please? Interested as to how that setup works.

How did you set over the job on the magnetic chuck to the MT angle, bearing in mind the relationship to the sliding axis? How DOES the sliding axis work? Does the mag-chuck slide, or the grinding head, ie, what moves to make the abrasive wheel move in and out of the job? Can't see from the photo - is that a commercial grinder or a shop built one ( the whole machine, not just the grinding head) Maybe some more photos of the whole thing from different angles.

Looks interesting!

Hi Joe

It is easier to explain if you view the 1st photo ,the machine is a home
built fabricated machine and initially was styled using the basic dimensions
of a Myford MG 12 grinder but at about 2/3ds size.From this the table
moves left/right and the grinding head fore and aft just the same as a normal
cylindrical grinder.The protruding shaft housing just above and behind the
tail stock is the shaft used for surface grinding,for this the the head and
tail stocks are removed along with the swiveling sub table the head swivels
round 90 deg and then the machine can be used as a surface grinder
as seen in the 2nd photo.In front of the table there are 2 micrometer
adjustments for the stop bar,the machine has a 2 axis dro the table has a
5 um scale the crossfeed a 1um scale, to set the angle for the morse taper
a true running test bar was mounted on the nose of the rotary table and the
table traverse set to 5.125 inch at this length a difference of .128 inch is
correct for a 2 morse taper half angle.Setting the rotary table on the mag
chuck and using a dti and the dro to check and set this measurement.
As the grinding head height can be set anywhere is is a simple matter
to align using centres in the spindle and the work.

Continued
The internal grinding spindle assembly mounts to the surface grinding
spindle housing with 4 bolts and a clamp and is driven from the spindle.
The 3rd photo here shows the workhead at the far end of the table here
also having the 2 morse taper being ground in situ.The internal grinding
spindle swings up as you can see by the shape of the mounting bracket.
For sizes above 10mm i use bore gauges as these are relatively long
and would foul a fixed spindle ,the mechanism has a quick release and
uses spring pressure to hold providing a constant force for a repeatable
repositioning. The work head mounts on a column similar to a Quorn
grinding machine but much larger and is made in such a way that the relative
centerline relative to the table has eight different positions.As the head can
swing 360 deg and can point up of down by about 30 deg with
work mounted it is possible to get an out of bounds setup ,to some extent
having this arrangement makes this less likely.
Initially i used water based coolant but got fed up fairly quickly about the mess
with this and having to take the parts off the table to clean them,leaving the machine
after use resulted in little black spots after about a day ,rust ! ,that all had to go.
I use neat grinding oil now excelcut 433 is about a 10 grade oil and runs away
as fast as paraffin ,no rust problems no tramp oil no wheel loading and much
more pleasant to use.
Keeping it clean (the oil) with only a 15 litre tank presented a whole new load
of problems,eventually solved by controlling the way the oil runs off the
machine ,through a fine mesh filter to collect the large debris ,slowing the
passage of the oil down through a magnet array ,then through a centrifuge
of about 5000g finally into 2 tanks the lower one having a pumped filter
system with throw away filters.

The basic specification of the machine
Surface grinding
14 X 5 inches ( maximum traverse length 18 inches)
Maximum height 5 inch grinding wheel to table 9.500 inches.

Cylindrical grinding
14 inch between centres
Maximum diameter between centres 6.500 inches, the swiveling sub table allows
around 7 deg taper in either direction .
Grinding wheel sizes 4 inch to 8 inch dia 1/4 to 3/4 inch wide variable speed
spindle from around 2,000 to 4,700 rpm , internal spindle to 31,000 rpm.
It's been an interesting project that will probably never be finished in as
much as the list of things that i need to complete gets shorter but the
list of thing that i would like to make grows ever longer .
All about time i suppose.

John

For what it’s worth [probably not much] : various Kangoo filters are listed here

Today I put the SD card from my camera into the computer card reader to upload some photos, to be met with a "this drive needs formatting" message. After a short period of panic, I did some on-line research and downloaded a Linux application called TestDisk. This successfuly recovered the files from the card, some several times and also ones I had deleted. I have now edited the photos into appropriate folders and formatted the card for re-use.

The photo I wanted was the one showing my now completed knurling tool, which is below.

Had a couple of hours long lesson on using my new Tig welder. Went straight onto welding 1.5mm aluminium sheet. Gradually got the hang of doing runs along the sheet. Then tried to join two pieces with overlap and butt welds. Not very pretty at all at the present. Going to need lots and lots of practice.

assembled some parts I made for a single cylinder marine engine. I have been restoring the original one and decided to copy it using whatever I have in the shed, the crank disk is made from a cheap rotary table.

That is really a splendid achievement John. Very nice indeed.

Thanks for the run-down. Looks very commercial!

Journeyman -

Thank you. In fact I had found that video - wrong edition of the car though, with a lot of detail differences, so not applicable to mine.

Anyway I took it in for its annual service and MoT today - went through no problems, and they changed that pesky filter (though I didn't think to ask where it is!)

Steam Vehicles:

Still making and fitting the boiler mounting for the wagon. It's a right so-and-so of a job, but I'm beginning to see some light at the end of the tunnel. Unless it's more problems coming the other way!

Nearly finished the mechanics of the power feed for my VMB. Couple of pics:

img_20200513_121629283_hdr.jpg

After a bit of experience i've upgraded the motor to a 1.9 Nm from Zapp, much beefier than the Minibea. I lose a bit of travel but not significant. Now I can run the table at full speed at the end where the friction was too high for it even to work at minimum speed with the smaller motor. It seems to take less current too! Just shows how stepper motors have come on.

Lexar cards used to come with free retrieval software either on the card or could be downloaded with a code, so obviously a common occurrence. My camera cards are always formatted in camera, the other thing to watch for is maximum size of card, the older the camera the less likely to support larger capacities.

Well done Anthony, you have made a nice job and given yourself a very useful tool that is much easier to use than the plunge type knurler.

i don't know anything about computer card formatting however.

Brian

Decades ago I made a circle cutter/ router for B&D Minicraft rotary tool. I now needed to adapt this for my Dremel. The Minicraft had a very fine nose thread, something like .75mm pitch which gave a fine height adjustment for routing. As we have discussed elsewhere, the Dremel has a coarse pitch nose thread so I made an intermediate adapter with a 3/4" BSF thread for the Dremel and a 26tpi thread for height adjustment (which gives approximately 1mm height adjustment per revolution which is good enough for woodwork! )

cc1.jpg

cc2.jpg

For the record the Dremel thread was bored through to 17mm before screw cutting and finishing with a tap. The 26tpi threads were just screw cut on the lathe.

Stay well,

Rod
