Bravo.  Wil the suspension arms support this weight?

 

Thank you.

Sincerely,

G’day Mark,

 

Thanks for commenting. Unlikely over time. The purpose of the hexagonal recesses in the lower hull is to fit bolts that’ll be taking the weight of the model.

More work on the glacis & trim vane. 

This is the stl of the glacis. 
 

 

Sliced into gcode. 
 

 

And printed. 
 

 

Compared to its Thingiverse counterpart. 
 

 

Test fit on the hull. Some cleanup required. 
 

 

Some post print verification of the tolerances. Whoops!

 

 

And the CAD model as at this morning. 
 

 

 

Thanks for looking in.

>So< close to finishing off the glacis, trim vane, & fittings!

 

Completing the lights, blackouts, & horn mean that there’s only the indicators to go. 
 

 

Like any model, this design started simply & is the aggregate of finer bits & pieces. 
 

 

Thanks for looking in.

A mid-week day off meant to progress could be made. 
 

First, detecting & correcting the turret spacer ring location. 
 

 

Its a scale inch to the rear, so had to be shifted forward, while keeping everything else in the same location. 
 

 

Of course, this correction necessitates a reprint. I was already printing a combined roof/glacis, which is now redundant. 
 

 

Turned to the exhaust, which took a few attempts. 
 

 

Got there in the end. 
 

 

The light clusters on the glacis took a bit of work, as did the indicators & their cages. 
 

 

Finished off the rear light clusters. 
 

 

As well as the ballistic shrouds & started the Diehl tracks. They’ll be linked with metal tubing. 
 

 

The 1:1 has 61 shoes on the LHS and 62 on the right, for a total of 123 shoes. The scale width of the track is 23.9mm. ‘Dual pin’ means two, 23.9mm-long pins per track, which calcs out to a bill of materials of ~5,879mm of 1.1mm metal rod. A lazy 5.9 metres or 19 feet! That’ll be fun. 
 

Thanks for looking in.

When I was using the T50 turret, the armament was a Browning M2 HB .50 cal & a Browning .30 cal…in 1998!

 

For the model, I’m using Aber turned brass barrels. Thankfully there’s aftermarket WW2 barrels in 1:16. 
 

 

 

This will be one part of the model that has to interface with someone else’s parts.

 

Another view.

 

 

Thanks for looking in.

During a periodic reference check of contemporaneous photos of ‘my’ M113, I noticed that the engine bay fire extinguisher pull housing was different to the standard one I’d modelled. 

 

The standard rectangular one is visible behind the triangular antenna brush guard. 


 

Turns out ARN134329 had an oddball one. 

 

 

Also realised that I may have to turn up a flash hider for the 30 cal. 
 

The internet provided some decent references from a Canadian work instruction to modify US M6 flash hiders for whatever purpose. 
 

 

Seen here modelled, with the mocked up 50 cal to help with the visualisation. 
 

 

From the other side. 
 

 

The now-redundant combined glacis/roof print has finished. 
 

 

Noting that those are one-inch squares. 
 

Thanks for looking in. 

 

[GMK]

Diehl 513A track is done! Just have to print 123 x track shoes & 246 x end connectors!

 

Inner face:

 

Outer face:

 

Also corrected the exhaust pipe from the curved to the bent variety. 
 

 

 

Here’s a side view - ignore the track spacing. 
 

 

Thanks for looking in.

Dayum!

Back in 2001 I started working for the ADF as a civilian....in the drawing office.  Had access to all the factory drawings for the M113, M548, and ASLAV, among other things.  I even did a 3D model of the M113 and M548 for a couple of projects I was working on at the time..

At least you got paid to model them! I just crewed them. 
 

I’ve started to resin print the detail elements to check for fit. 
 

 

There’s still a lot of cleanup to do, but the test fit went okay. 
 

 

Ignore how cockeyed it all looks, that’ll be fixed on final assembly. 
 

 

Thanks for looking in. 

[GMK]

Wanting to get a look at just how much cleanup was going to be required, I primed the upper hull & glacis with high build automotive primer.  
 

 

Pretty happy with this, especially considering that it’s a single piece. 
 

Thanks for looking in.

Love it, any close ups.

Thanks, Ryan. 
 

I’ll wait until the cleanup is complete for closeups so I can A/B it. 

[Ryan]

thanks I was curious what it looked like before cleaning up.

Queriendo echar un vistazo a cuánta limpieza iba a ser necesaria, imprimé la parte superior del casco y el glacis con imprimación automotriz de alto espesor.  
 

 

Muy contento con esto, especialmente teniendo en cuenta que es una sola pieza. 
 

Gracias por mirar 

 

 

I have to admit that I did not like the 3D printing of this vehicle at all, since there were striations everywhere. But, once cleaned, the aspect is magnificent!! Now I follow this construction with enthusiasm!!
