Big As MAZ

123 posts in this topic

Hey All,

 

  I have been cruising through here for a while now, looking at some of the fine builds.  I was wondering if anybody would be interested in my 1/20 scale scratch built MAZ 537g.  I think AFV builders might want to see what going on with this big build, altho not strictly AFV.  I'll start posting as soon as I can figure out the photo deal if I get a little feedback.

 

Thanks

Hey All,

So this is my first posting of a project in the Armour forum. Altho not an AFV build, it still hauls all you all around. So a good place I thought for a military truck build. 

 

 

I wanted to build this truck project because I really like the big industrial design and feel, and also the scale of this large Russian beauty. I have several different model kits of this subject, so I will be building a conglomeration of what I have and what info I can find on this subject.

I have three kits that I will be combining the info from, to scratch build a big model of this big truck. I have a 1/35 plastic version from Trumpeter. I have a 1/25 card version from Model-Kom. And I have a 1/35 card version from E63.

The Trumpeter kit.

IMG_1486_zpsu7kcm5en.jpg

The Trumpeter has the typical great Trumpeter detail to copy from, but really sucks on the design of the model it's self, with no engine and transmission, and just half a transfer case...etc. The list goes on, for the amount of money.

The Model-Kom kit.

IMG_1496_zpsxhohrav6.jpg

The model-Kom kit has great detail to use as a reference, but I'm not so crazy about the color scheme. I could paint it maybe, but I will hold on to it for another days build.

The E63 card kit.

This is a download kit from Enrico, in Italy. This is a great super detailed kit. He has some really detailed models, some for free download.

A Russian Beauty

w02002_4080853.jpg

For a paint scheme I have chosen this beauty to try to copy. I like the original Russian green under the orange paint, and all the weathering. A real opportunity to get crazy with the paint job.

The MAZ 537 G build.

 

Of course with any build you have to start with the foundation.

I started with cutting out the frame rails.

IMG_1469_zpsdisibsia.jpg

To get thing straight and tight when I build, I sometimes use a set of magnets to hold things square.

IMG_1471_zpscmk6j12s.jpg

IMG_1448_zpsfnd276gh.jpg

frame rails.

IMG_1472_zpsvzbmp2kt.jpg

IMG_1469_zpsdisibsia.jpg

Once I have all the rails put together I trimmed up the ends and glued the rails together. I wanted to maintain the look of the real MAZ frame, which has round bends and open corners where the frame rails are joined..

w02002_3381149.jpg

IMG_1473_zpsk2iq4cap.jpg

IMG_1474_zpsqd5oli0c.jpg

And to build the front end I had to build a bumper. The parts

IMG_1477_zpsdv0qhkfv.jpg

The front bumper installed.

IMG_1478_zps1csvrrn2.jpg

IMG_1479_zps0pcsgz2t.jpg

This is the frame that I built as of today.

IMG_1481_zpspdah8mgs.jpg

IMG_1480_zpsjmcmchfz.jpgIMG_1482_zpsdwuxztmp.jpg

So this is where I decided to stop for now. The frame feels strong and stable and ready to accept the drive train. I will next build the outside frame supports and start with suspension bracing.

Be back sometime soon, Rich

Hello, 

Your build is giving me another reason to keep checking LSM!  I enjoy scratch building but I am not even near your level of skill to attempt such a project. 

Good job!

Thanks guys!  This is going to be big with an open ended time line to build.  The combination that I plan to build is a monster 10,000 part build.  I hope everyone will like this presentation.

Hey All,

A little more work on the Maz. I managed to build the three bottom frame braces (or stiffeners). Finding photos of unobstructed views of things at the bottom of the frame can get tough sometimes.

The Model-Kom kit and the E63 kit have different shaped frame braces. And the Trumpeter kit did not even address this issue. From what I could find online, what I chose is close enough to pass. If we have any rivet counters out there watching, this build is going to drive you nuts. Because I'm just building this like I would as if it was in my back yard. If it works, it works.

The parts.

IMG_1497_zps01ojud9j.jpg

These are the parts for one brace.

IMG_1501_zpsos8ux3l6.jpg

Assembly.

IMG_1502_zps3rlw7gyv.jpg

IMG_1503_zpsb47vppfe.jpg

IMG_1498_zpscr6jlmvl.jpg

In the photo above you can see that I use Dressmaker Pins for my rivets. I can get a small package of 1000 for less than a dollar.

The three braces.

IMG_1504_zpsafvvtv8k.jpg

IMG_1505_zps71luurpt.jpg

It looks like the braces are a nice fit.

I think the next thing on this build is the internal structure of the four axles shafts where they come throu the frame.

Hey All,

I thought I would show how I have built the Tow Box. The Tow Box is the large anchor structure for the towhook. I don't know if it's called a Tow Box, I just pulled that out of my as .

w02002_3037872.jpg

The parts were not to numerous, but a lot of detail in a small piece.

Parts for the tow hook...

IMG_1526_zpsmijkmzr1.jpg

Building the box...

IMG_1524_zpszctaflcs.jpg

IMG_1525_zpsau3udyy0.jpg

The anchor bolt for the tow hook goes all the way through the tow box and ends with a large nut to hold all secure. I first had to get all the parts aligned and measured.

IMG_1527_zpse2fjgc58.jpg

Then the construction of the Tow Bar... I used Evergreen rod and tubes to sculpt the anchor nut...

IMG_1528_zpsrldwngau.jpg

IMG_1529_zps6b0bo6t6.jpg

Then I had to sculpt the tow hook and detail all...

IMG_1530_zps9p2sny55.jpg

Next I added the details for the anchor plate at the end of the tow box...

IMG_1532_zpsgckdw0n7.jpg

and detailed the rest of the end.

IMG_1533_zpsaawxhbe2.jpg

The tow hook stayed in place and look good...

IMG_1531_zpsw3rss9iq.jpg

The tow box is finished and ready to be instaled...

IMG_1534_zpsvvbxctw7.jpg

IMG_1535_zpse2ukwyxd.jpg

This little part took about three days to build...once I figured out the dimensions all went smoothly, just slow.

Thanks all for looking I'l be back with more frame items, Rich

GusMac,  

  

I used to cut these with a small hobby wire cutter.  However, the stuff did  fly everywhere.  I wrapped a towel around my hands when cutting, but this all got to be such a hassle that I found a new product to use.  Pin in the feet and butt had to stop.  I'll show photos of the new product.

 

Thanks 

Rich

Hey Guys,

 

I have managed to get some small steps done on the Maz. I have built the cross members for the axles and installed the internal frame bracing, along with the permanent install of the tow box.

This is how I built the cross members for the axles.

IMG_1516_zpsdzsxwz9o.jpg

IMG_1517_zps9anl2rsn.jpg

IMG_1521_zpstnqqoyzq.jpg

Then the install.

IMG_1545_zps3lfkou7k.jpg

IMG_1546_zpsfmutypvh.jpg

IMG_1547_zpsbuawtxhl.jpg

Now that I have the internal bracing installed along with the axle cross members, I can now start with the exterior axle components. I do have more internal frame braces to install, however I would like to install the drive train first so bracing dose not interfere with that install.

I next need to perforate the frame with several openings for the axle passthrough. I'll show that next.

That's it for now. Be back later.

Hey Altogether,

 

This is a quick response to GusMac and the removal of the pin heads as rivets.

 

 

I have replaced the pins with the resin rivets from MasterClub. The pins were nice but hard to get ones with domed heads and not all are round, just not real consistent.

IMG_1738_zpsuv62mom6.jpg

IMG_1737_zpsacmcdtym.jpg

The rivets are really great to work with.  Yurislov, at MasterClub was easy to work with and his rivets and screws are just gorgeous to look at.

 

Thanks All,  Be Back Later...

Hey,

 

  Thanks for looking at this everyone.

  I have built the cross frame braces that go over the axles.  The parts...18 parts per side brace...

 

IMG_1746_zps8sv5jyj5.jpg

 

I will mount these in their location, however I will not put the cross brace in just yet. I will have a ton of stuff to place under the braces when I install the drive line.

 

IMG_1750_zpst4rfgu5h.jpg

 

IMG_1748_zpsp1kghyvs.jpg

 

  I'm now at the suspension section... 

 

IMG_1749_zpslpqdpypt.jpg

 

 I'll be back with the suspension shortly.

 

  Thanks All, Rich

Love the work!  I've also struggled with large-scale rivets.  Pinheads, resin decals...  I feel your pain!  

 

:D

 

i'm going to look up your source at MasterClub - thank you for the reference!

Just thought of a question - something that you've obviously mastered, but that I have yet to deal with...  That is forming and gluing compound curves from flat/straight plastic strip.

 

I've been utterly spoiled in that department as most of my scratch-building has been in either metal or wood, both of which are simple to bend and hold their shape after the fact.  When I've done scratch-building with plastic it's been either straight bits or pieces thin and small enough that I could use CA to hold them.  So what is your approach to clamping/fixing fairly thick plastic curves/twists/bends while plastic cement dries?

Thanks for the nice comments guys!  This will be fun, I'm just getting started.

 

Crazypoet,  

  Great question...I have a few years of card modeling under my belt.  One day I got a really cool card kit that I thought was to good to be made out of card, a lesser permanent material than styrene.  If I can build it out of card I can build it out styrene, same difference.  Flat patterns.  It just takes good patterns to work from.  As for the gluing, I don't use glue, no drying.  I use a chemical compound called methylene chloride.  "Plastic Weld" in common terms. This stuff is about as fast as super glue when I use it, and the seams sand nicely.  The thickest styrene sheet I work with is a 0.03 - .75mm.  This was the thickest material that I got used to working, without breaking or cracking. If I need thicker in a particular spot I just double up the layers.  When I go about joining, I just weld and hold as I go, just like I did when building out of card.  Only I don't have to hold as long as I did with the white glue for card.

 

  I have some interesting curves in the cab of this build that will be fun when I get to them.  But mostly, this build is just nuts and bolts... but stick a round to see how badly I mess thing up...could be fun.

 

Thanks, Rich

Thanks for the info on the rivets Rich. The results look impressive.

Very interesting to see your thoughts on the card thickness as well. Just away to start a build with some scratch building in Evergreen sheet which will be new to me, so the lamination of thin card is another option to ponder.

Great to pass any info along to you guys.  I try to show briefly, anything that I think might be interesting, so ask any questions.  Thanks

Thanks for the info and the comparisons - I should have caught on sooner about the similarities to heavy card and paper.  [smacks forehead]

 

That said, the paper kits that I've seen were aimed at kids - until I saw that Model-Kom kit you referenced above!  I'm impressed with what can be done with good patterns

Hey Guys,

 

Time to start with the suspension system.  I want to copy the photo below to get the components for the rear suspension.

So I thought I would use the "A" arms that are in the photo below...

w02002_8628241.jpg

The heavy duty cast iron look of the forged "A" arms above, seams and all, I will do a resin cast.

I cut out the parts and built the lower "A" arm...

IMG_1594_zpsh3h45tia.jpg

IMG_1595_zpsedeirlse.jpg

I next had to shape the styrene into what looked like the lower arms in the photos I had...

IMG_1603_zpsx2zxayv8.jpg

Once I got the shape I was after, I built half of the mold to make four of these...

IMG_1604_zps1o7rojbh.jpg

IMG_1609_zpsfph8ijp7.jpg

The four copies...

IMG_1610_zpsapmjyppx.jpg

The goal here was to make a one piece cast part that looked like the forged original...seam lines and all...

IMG_1615_zps0yreudxu.jpg

I now need to clean up the rest of the copies and get ready to install. I still have the star caps at the ends of the arms that need casting, about 36 of those altogether.

I'll be back in a while with the casting of the upper a-arms...later all.

   I have the components worked out for the rear suspension.

 

  I built the axle pass through collar. This is close to the production shape, and fits with the other components...

 

IMG_1761_zpszgkraauz.jpg

 

The major parts for the rear suspension...

 

IMG_1762_zpsncksriok.jpg

 

 first version of these components, I built the version that was supplied with the paper kit by Model-Kom.  See below...

 

IMG_1764_zpsgwn92cbk.jpg

 

You can see how the mounting rings for the wheel axles, are just rings with no detail.  I rebuilt the mounting hub with the back ring detailed with the form curve that it has in the photos...

 

IMG_1768_zps13lyiw2b.jpg

 

Fit to the frame (somewhat)...

 

IMG_1769_zps844wqvk3.jpg

 

  Now that I have these worked out, I will clean and primmer, then I can cast the four copies for the whole rear end. I need to cast eight of the axle pass through collars tho. 

 

  I'll be back with the casting next time.  Thanks for looking.

Are you going to have the suspension fixed, or build it to articulate?

 

watching this build "over your shoulder" is a joy - thank you for sharing all the little steps
