  I’m wondering what’s the rationale for having changed the name (and dimensions)
of
 
Part No: 18654  Name: Technic, Liftarm Thick 1 x 1 (Spacer)
* 
18654 Technic, Liftarm Thick 1 x 1 (Spacer)
Parts: Technic, Liftarm
from “1 L” to “2/3 L”.

I can’t see where it’s 0.67L.

Especially if I compare it to
 
Part No: 62462  Name: Technic, Pin Connector Round 2L with Slot (Pin Joiner Round)
* 
62462 Technic, Pin Connector Round 2L with Slot (Pin Joiner Round)
Parts: Technic, Connector
 
Part No: 6538  Name: Technic, Axle Connector 2L (Ridged Undetermined Type)
* 
6538 Technic, Axle Connector 2L (Ridged Undetermined Type)
Parts: Technic, Connector
and their variants, or with
 
Part No: 43857  Name: Technic, Liftarm Thick 1 x 2
* 
43857 Technic, Liftarm Thick 1 x 2
Parts: Technic, Liftarm
and other liftarms/beams, or all the connectors with “# L” in their descriptions.

In the same way, its new dimensions are 1 x 1 x 0.67. As it’s a cylinder, it
means the 0.67 is supposed to apply to its height. But its height is exactly
1 stud, which is 5/6th = 0.83 brick, not 2/3rd = 0.67, and, anyway, “L” means
stud, not brick, so 1 = 1.

Therefore, I strongly believe its name should have stayed “Technic, Pin Connector
Round 1 L” and its dimensions should be 1 x 1 x 0.83.
(Actually, its diameter is a shy less than 1 stud, so its dimensions should be
0.9something x 0.9something x 0.83 but all the liftarms have the same width and
are said to be 1 stud wide.)


Not filing a proper catalogue change request because I really would want to know
the reasoning here, not play ping-pong.

I don't really care too much right now about the dimensions of the part.
What I care about more is how it is named and categorized. I have never thought
of it as a "Pin Connector" because it actually can't connect pins at all.
It is basically a 1L bushing for pins in the same way
 
Part No: 3713  Name: Technic Bush
* 
3713 Technic Bush
Parts: Technic
is a 1L bushing for axles.

Cheers,

How can factual correctness be less important than a choice of how to categorise
it? I'd say #1 is to get the facts straight, and after that, we can go and
organise it. But what SylvainLS points out here is a real mistake that should
be corrected. It's a small thing in itself, but the correctness of the catalog
is one of the core features that drive Bricklink. I'd say it's the main
selling point of Bricklink compared to BrickOwl.

Maybe someone thought it was 2 plates high, thus 2/3.. but it really raises the
question why it was ever approved.

I like this sentence.

Me too.
Well, except for the example, as there are plates with grooves
 
Part No: 3030a  Name: Plate 4 x 10 with Groove
* 
3030a Plate 4 x 10 with Groove
Parts: Plate
and tiles/plates variants with and without groove

* 
41740 Plate, Modified 1 x 4 with 2 Studs with Groove
Parts: Plate, Modified
 
Part No: 92593  Name: Plate, Modified 1 x 4 with 2 Studs without Groove
* 
92593 Plate, Modified 1 x 4 with 2 Studs without Groove
Parts: Plate, Modified

(And the jumpers too….)

Yeah... the fact that there's a variation that would span across categories
if you take the groove as the defining factor, kind of kills that idea pretty
effectively.

Anyway, in my opinion it's not a huge deal that it's not perfect. TileMod
and PlateMod are two fairly big categories, nicely sized if you ask me. God forbid
someone would decide to merge them together because there's no principal
distinction possible. I'd rather put up with a bit of inconsistency that's
very easy to learn, than one huge category that is difficult to manage, both
in terms of browsing it online as well as storing it for me and other stores
who have category based sorting..
And we have the forum for venting inconsistency frustrations, which works pretty
well too

  why is

6576 Plate, Modified 4 x 8 with Studs in Center

a plate modified when
 
Part No: 88646  Name: Tile, Modified 3 x 4 with 4 Studs in Center
* 
88646 Tile, Modified 3 x 4 with 4 Studs in Center
Parts: Tile, Modified
is a tile modified?

There is no consistency, both could be either.

You could say the parent of 6576 is either a 4x8 plate or 4x8 tile, but the 4x8
tile doesn't exist so 6576 must be a modified plate.

Or you could say you add 12 studs to the tile or remove 20 studs from the plate,
so it is closer to being a tile than a plate.

For 88646, neither the parent tile or plate exist. You add 4 studs to the tile,
but remove 8 from the plate and also have to shift them. So does that make it
a modified tile rather than modified plate?

If so, then the 1x2 jumper should be a modified tile (add one stud, vs remove
and move one stud). Similarly a 2x2 jumper is definitely closer to a tile than
a plate but is still a modified plate. Worse still, this pack of jumper bricks:
 
Set No: 10115  Name: Jumper Bricks
* 
10115-1 (Inv) Jumper Bricks
80 Parts, 2001
Sets: Bulk Bricks
contains no bricks at all.

 
Part No: 33909  Name: Tile, Modified 2 x 2 with Studs on Edge
* 
33909 Tile, Modified 2 x 2 with Studs on Edge
Parts: Tile, Modified
is clearly a 2x2 plate with two studs removed, but it is a modified tile.

 
Part No: 6180  Name: Tile, Modified 4 x 6 with Studs on Edges
* 
6180 Tile, Modified 4 x 6 with Studs on Edges
Parts: Tile, Modified
is also a modified tile rather than plate (compare to 6576).

Exactly, the jumpers always seemed much more tile-like to me than that "tile".

I guess the only relevant answer to this issue is: This was acknowledged by the
previous catmin Stormchaser, he said the concepts of plate and tile needed to
be principally redefined before these things could be classified properly. If
that's also what the new catalog management will do is not yet clear. Either
way, if you don't have principal characteristics of what constitutes a tile
or plate (for example groove = tile), any classification is going to be inconsistent
and a matter of opinion.

  Guys,

Appreciate both your responses as they shed some much needed light. It is a little
strange that BrickStock doesn't seem to have a Help section explaining all
this.

HI there sorry I missed this thread earlier

Please bear in mind that Teup's comments do not really apply to the UK.

Well.... it does. I'm just saying that the averge price that you see here
in Bricklink is not equal to the average price in Brickstock. These do not match.
Parting out a set at average price on Bricklink will result in you having higher
priced items than parting out that same set at average price in Brickstock.

Whether you wish to match the price of other stores including VAT, or whether
you want to compare yourself to their prices ex VAT... yeah, here you're
right, those are all your own business decisions.

But the fact is that the Bricklink priceguide does not match the Brickstock priceguide.
It's important to be aware of this. Pricing at the Brickstock average is
pricing below the Bricklink average.

As I said or at least implied - average pricing in the UK includes VAT and once
you adjust the downloaded price in Brickstock it matches as close as can be expected.
Nothing is perfect and Brickstock could use work on this but so could Bricklink.
The currency conversion is a bigger issue than vat as it applies to all apart
from the USA. Bricklink could do a lot more there and haven't.

Do USA prices include sales tax ? That differs depending on whether you ship
in state or out of state. So the whole pricing scenario based on Bricklink is
a bit shaky - it should be used as a guideline only not a 'real figure'.

Do the last 6 months sales prices include tzes of any kind or is it net. If something
sells at 10p that is the price that should be reflected. If you are vat registered
and can claim back the vat go for it - but for the majority of UK sellers that
is not the position - what you see is what you pay and that is what your cost
is. Pricing needs to be based on cost + not some weird price guide which no one
fully understands. They can tell you how it works but when you look at it you
only see a single figure not how that figures has been made up.

Again for example 1000 units sold at 8p one month but 10p the next month so average
is 9p, but that is not remotely accurate. If the currency conversion rate has
fluctuated then they might be selling at a totally different price, or the same
price.

The price guide needs major re-working and I do not believe that is going to
happen. It currently is a very crude tool which has to be manipulated to get
anywhere near reality.

If the design of the system is anywhere near what it should be there is only
one table with prices and those are converted from an exchange rate table each
time they are displayed, Somehow I doubt that.

Well, I guess that's all true enough. Some take the priceguide as just a
guide, some ignore it, some take it as some holy prescription. I tend to be kind
of the latter type... but that's not because I think these numbers are inherently
all so correct (you pointed out some of its shortcomings) but I just remember
that when I was a buyer I'd check the priceguide on everything and buy things
depending on them being at or below average. So it's more a presentation
matter that I want my prices to line up with that reference than that I give
that reference any "scientific" credit. So the priceguide is my starting point
and from there I decide what to buy. Instead of first buying, and then based
on what I spent deciding what my prices should be.

But that's just a personal decision of course. You could invent any kind
of pricing policy for yourself and there are good arguments for all of them.
Maybe in some of them it is actually a blessing that Brickstock downloads the
ex.VAT value.

But in what ever case, no matter what your pricing policy is, and no matter whether
you are VAT registered, no matter if you're a buyer or a seller, if you live
in the area where Bricklink displays prices including VAT for, for all these
people, it is just important to know this difference: priceguide on BL includes
VAT, priceguide downloaded through Brickstock excludes VAT. Then you can do whatever
you want with that information. But knowing it is important as it prevents us
from sleepwalking into a race to the bottom.
