FAQ
Frequently Asked Questions:
Below is a list of the most common questions people ask me. Please read these before you ask me something – the answer may be already there, and it will save your time – not to mention mine.
Where do you buy all these things, and how do I get them?
I don’t buy these things, I create them myself. These are not official LEGO sets, just custom designs not available for sale.
Can I buy any of these from you?
Not really. There are basically two reasons for this: firstly, I only build every construction once and then take it apart, without creating any form of instruction. Hence, if I were to re-build a specific construction for you, I would have to rely mainly on my memory. Secondly, and more importantly, all my constructions are very ‘technic’ in nature – they contain a number of moving parts and mechanism that may get damaged and malfunction. If you want to buy them, you probably want to put their functions into some use, and it means I can’t guarantee they will work properly in every condition, not to mention the problems with shipping. They can’t be glued solid or reinforced – it’s just the way the bricks work; they can be put together, but they can be put apart as well. And I have no time for some emergency service or handling dissatisfied customers, sorry.
If the above does not discourage you, there is obviously always a space for negotiations. Be aware, however, that the specialized parts I’m often using and plenty of labour needed must reflect on the final price.
Do you make instructions?
Usually I don’t, and there is a number of reasons for it. Creating instructions takes usually much more time than the actual building did, and hence it would reduce the number of my constructions at least by half. I tend to use plenty of specialized parts that are rare and expensive – so even with the instruction in hand, you would most likely have to do a lot of shopping, and then perhaps feel unhappy about the way you spent your money. Finally, I deeply believe that creativity is what LEGO is about. So I’m taking many photos and I’m explaining how the mechanisms are built and on what principles they work. This plus your creativity should be enough. If you want complete, step-by-step instructions – go buy some LEGO sets.
What software are you using to create 3D drawings and schemes?
I’m using MLCad for modelling and LDView for rendering.
Can you send me more photos of something?
No. The construction you’re interested in is most probably already taken apart, and I really don’t keep any photos hidden from you. I only keep the photos I have published. If they’re not enough – sorry, there really is no more.
Does “Future Projects” page list all your future projects?
No. I have a number of secret projects, which are highly experimental and hence more likely to fail. I don’t list them there to avoid being hard-pressed, as they are more unusual and more difficult to complete than the regular ones. But if such a project enters a stage at which it’s very likely to be completed, it will be listed in the “Currently building” section under a code name.
Can I use any of your ideas?
Of course, that’s why I publish them. I believe that the ideas should be exchanged in the Lego builders community freely.
Do I have to credit you when I use some of your ideas?
Not necessarily. It will be nice if you do, but that’s not really the point, and I don’t require it. I’d rather see my ideas developed further and put into a good use, than look around for credits.
Are you keeping all your constructions?
I’m keeping none. I take them all apart in order to build something next, to re-use the parts. I have no regrets about it – anything I build can be recreated, and even if I kept it intact, I would feel compelled to improve something in it sooner or later. My need for building is simply stronger than my need for looking at my creations.
How many parts do you have?
Probably less than you think. I’m not a collector, I only buy necessary parts, and I’m re-using the ones I already have. Moreover, I want to hold all my parts within my workbench, and that implies certain limits. There are approximately 50,000 parts in my current posession; for comparison, a large Lego Technic set can easily exceed 1500 parts count.
What does your workbench looks like?
Messy is the word, I guess. As you can see below, there’s one large pile of loose bricks plus some drawers, cases and containers with selected parts. It may look like some cataclysm has taken place here, but I’m actually quite comfortable with this setup.
Where do you get all your parts?
There are many sources available, starting with the LEGO Shop itself, including eBay and probably the most specialized: Bricklink.com. I’m shopping almost exclusively online, because the prices are more affordable that in local shops available to me.
Can you sell me some parts?
As mentioned above, there are numerous sources of LEGO parts available. Most of them are faster and cheaper than I could be.
Do you have some special technical education?
Not a bit, I’m a linguist by education and a webdesigner by profession. I simply have a strong interest in mechanics, and a plenty of experience with LEGO bricks. All I need to build is some mathematics, geometry and access to the Wikipedia.
You should show LEGO what you build, or work for them!
Thank you, actually the company is aware of my work and we do have a certain form of a co-operation. All I can tell is that I’m not a LEGO employee, but the company uses a little bit of my help in its development.
How come your photos look professionally edited?
I work as a webdesigner. Graphic design and post-processing of photos are essential part of my profession.
Are you a professional photographer?
No, I have little idea about professional photography. I’m using a DLSR camera, a pair of good lamps, and a big piece of paper as the background. Nothing really tricky.
What cameras are you using?
As of 2011, I am using Sony a33 camera for both photos & filming, and Casio Exilim EX-FS10 camera for slow-motion footage and for filming with camera attached to a model.
Are you building with LEGO bricks only?
Yes, as far as it’s possible. That means, I’m using both LEGO and non-LEGO strings, rubber bands and pneumatic hoses, as these originals parts are most difficult (and least rational) to buy. Other than that, it’s all original LEGO bricks down to the last single part. And I don’t modify, cut or glue my bricks.
Can you build something from the Star Wars theme?
I have no interest in Star Wars theme at all, sorry.
What’s the difference between terms “Truck Trial” and “Trial Truck”?
Truck Trial is the name of the competition. Trial Truck is the name of a vehicle built specifically for this competition.
Can you make instructions for some good Trial Truck?
No. It’s simply pointless – Truck Trial is a sport somewhat similar to F1 races, which means that there are no ultimate solutions nor ultimate vehicles. Construction of trucks used in the Truck Trial is continuously evolving, the improving of vehicles never really stops, and new solutions pop up every couple of months only to become outdated sooner or later. There are many different approaches to building, various builders focus on various aspects of their vehicles, and ever most successful trucks are being improved and experimented on. Some vehicles can perform excellent against certain types of obstacles while failing against other. I’m still trying to develop a decent, universal vehicle, but even if I succeed and create instruction, it will soon become worthless. Given the extreme complexity of Truck Trial vehicles and hence long time needed to create such an instruction, it would very likely be outdated by the time it’s finished.
Do you have something to do with the BrickShelf, since you created the statistics module?
No, I’m just a regular BrickShelf user. The statistics module is an entirely external piece of software.
When building in military theme, do you have some remorses?
Actually, I’m very picky about the military theme. I avoid building vehicles created by some controversial regimes, e.g. North Korean ones. Due to historical reasons, I don’t feel comfortable with German or Russian vehicles neither. I’m aware that e.g. the Tiger tank is very popular among Lego builders, but I just don’t feel like building it. Additionally, please keep in mind that when I build a military model, it is merely to express how fascinating engineering achievement it is, not to promote the purpose of it (which is killing), nor the country that created it. I may be a fan of tracked vehicles, and still not like what some of them are used for.
How come you build so much?
There is a number of experienced builders who work really fast. In my case, I believe imagination is the key: I don’t have to try out every solution that comes to my head, because often I can imagine how it would work without touching a single brick. It’s not difficult, it’s just a matter of experience and knowledge on the LEGO bricks. There is also a matter of planning – when I build something big, I’m trying to plan it in theory as much as possible. I’m checking the exact size of the mechanisms I want to include in it, I’m trying to figure out the best way to put them together. It takes little effort, and it’s really helpful, or even crucial in case of the most complex constructions.
How long does it take to build these things?
That varies a lot, depending on the complexity of a given model and the amount of spare time I have at the moment. In most cases, it’s between 3 and 6 weeks.


@ivan
You can use any idea you find here as you wish. I don’t know of any side-effects.
@Sariel
Can i use your “Compact pendular steered suspension” for my #8273 Tow Truck motorized version? are there any side effect?
@ivan
No. Try looking through instructions for some official Lego sets, like 8297 or 8436, that should help.
Hi Sariel,
I am new for Lego Technic. I bought a #8273 Tow truck. Further, I want to make it motorized. However, I don’t have any mechanical background. Do you have a link or instruction of how to make a differential and steering gear so that I can use a XL motor & M motor to make it move and turn? Thanks a lot!!!!!
ivan
@darksheep
Yes, I know Jerrec’s work. But he didn’t mention SC as a source of inspiration, and this tank is technically simple, even though it looks awesome.
http://www.e-klocki.com/2009/09/20/swiss-just-got-their-motors/ look at this . It kind of looks like the star craft tank. interesting i think.
@owen
No.
What i mean is do you have all of the sets on that page?
@owen
I’m not sure I understand the question. Setechnic.com was a French AFOLs community the last time I checked.
is setechnic.com all of the sets you have?
@Sariel
Yes i do think that would be pointless
please send me an email i think you have my address , i would like to talk to you about and idea i have . just don’t wana post it in a public forum just yet.
@darksheep
Yes, I’m familiar with SC vehicles and I had this tank under consideration actually. But its siege mode transformation is impossible to reproduce, except for a very large scale. I mean the scale at which you can put motors inside the tracks. And what good is a siege tank that has no siege mode?
Hi . I love your work it is amazing really really is !!!
I have an idea for you that you might like what about building this tank (http://www.starcraft2.com/features/terran/siegetank.xml). Its got grate functionality think it would be challenging and think it is some thing you might like to do and i would like to see
I would try my self but i am don’t have lots of experience building and i am new to lego (back after 10 years ) i also have a lack of money and parts , plus i stay in South Africa its hard getting stuff hear .
Any way keep up the good work
Dzięki. Napotkałem jeszcze jeden problem. Batery box często mi się przegrzewa niezależnie od ilości podłączonych silniczków. Myślę jednak, że to problem akumulatorów.
@Mikołaj
Nie wiem, teoretycznie wytrzyma dopóki się nie zagrzeje do takiej temperatury przy której zabezpieczenia w elektronice go wyłączą.
Mam pytanie. Ile czasu (mniej więcej)pf medium może wytrzymać pod napięciem bez ruchu? Np. w układzie sterowniczym pojazdu snow white z technic bricka?
@capb
Try this: http://sariel.pl/2009/01/direction-sensitive-gearbox/
@capb
If so, what is it called?
Hey, is it possible for a single motor to have the ?output? wheel to always turn one way with the motor turning clockwise and counter clockwise?
@echowave
Yes, I’m using bracings that are explained in the Ideas category.
hey sariel
i have a question about the new differential included in the new off road truck (8297) when i tried to attach a motor to that set, the gear seems to slip at a specific point (where a bevel gear is loaded). when watching your models run on youtube, this problem doesn’t seem to happen.
do you have any solutions?
Thanks
@Smithy
I can show how the photos are taken, the entire setup. As for the WordPress, well, it’s simply the newest version with one of the most popular themes and a handful of popular plugins. Nothing really tricky.
I love your models. I’m envious of the way you’ve been able to sue the remote control functions.
Would it be possible for you to write an article about your actual website? Where you host it, the plugs in you use for wordpress, how you take the videos and stuff like that? I’ve tried to find out how you do the photos bit of your posts and haven’t found out how.
@legokid
Listen. It’s 50 cm long. If you need a wire that long, you use it. If you need a shorter one, you try the 20 cm one. Some models need 50 cm, some need less. That’s it.
well I mean is it to long becos it is 50 cm long and that is relly long
@legokid
I have it. What you mean ‘too long’?
OH! sorry I mene 50cm!
do you have the power function 20cm long wire and is it to long?
@crawlerdude
It just needs the cabin and the front winch. It should be ready for the race on September 5th, and I will probably publish it shortly after.
how is the alvis coming?
@legokid
Yes.
did you get the lego technic bulldozer and was it a good buy.
@legokid
Does it matter? I don’t see any point in your question. And please try to avoid posting several comments in a row. Plus there are things like the capital letters and punctuation marks, if you missed that.
if you want to tell me
but how many
@legokid
Just enough.
how many xl and m motors,switch,light,irand ir remote do you have? I relly want to know.
@owen
No, all my motors are fine.
do your power funtion motors ever just stop working? becace i have and 8 motors total and recently 5 have stopped working . do you have ideas that can help me fix my problem? well greatw work on everything.
@bobsurankle
Yes, check the TechnicBricks blog, there are several solutions that do that.
thank you for that, sorry, but i have another question has sprung to mind: do you know of a way to put 2 linear actuators end to end to make a really long one?
@bobsurankle
It has some biblical meaning: http://en.wikipedia.org/wiki/Sariel
But basically it’s just a nickname I picked up when I entered the AFOLs community. I was looking for something short, distinctive, easy to spell and easy to remember, that’s it.
Can i ask… where does the name “sariel” come from?
@Sariel
Ah, good stuff! I missed that part of the post. Will look into it, seems very interesting. Thanks for the redirect, much appreciated.
@Leroy
Perhaps my live axle design is what you’re looking for? It’s presented in the post about the SandRail.
@Sariel
Yup I noticed in the model video’s, but I mean in the more complex suspensions, like the compact pendular steered suspension. For example a very sturdy suspension like that, but with shock absorbers.
I’m just looking for alternatives to the simple Lego solution, since I’m thinking of a model that might weigh a bit more
@Leroy
You mean shock absorbers? Well, most of my suspensions use shock absorbers.
I love your work at the models so far, a very good source of inspiration.
I studied your suspension designs thoroughly, and trying to modify them with shock breakers. Maybe a challenge to design a good suspension system with shock breakers included?
To be honest, I’m curious with what you can come up with
@crawlerdude
Because trial trucks take an enormous amount of work to complete, equal to building 3 or more regular constructions. And besides I don’t need many trial trucks, I only need one that performs well. I’m building the Alvis right now, and we’ll see how it turns out.
Dear sariel,
why dont you build more trial trucks?
