Hi Simon,
Many thanks. There is plenty more to come: the engine, the turret, Zimmerit, recoil, smoke and flash, hatches, camouflage and markings plus weathering.

Hi Tim,
Many thanks.

Hi All,
Update 19 Jun 24
Items epoxied to cover top...
20240614_095655-doc.jpg
View from below showing use of countersunk fasteners...
20240614_095714-doc.jpg
I will use Milliput to fill the hollows to level surface for the bonding tape.
Inner sheet bonded in place to give the characteristic milled edge and relief for the main vent weld...

Front vent:
3D printed part with deliberately rough weld detail added...

View of underside, I included a filler piece in the large aperture to prevent any distortion during printing.

Front vent in place...

Another test fit of hatch...
20240618_121047-doc.jpg
Needs a little (0.5 to 1mm?) skimmed off the front.

(NOTE: all my 3D parts are created in Fusion360 and printed by Shapeways. If anyone is interested, they could be made available for sale. I cannot guarantee that they are all drop-in replacements on a standard Armortek Tiger 1 kit but that might be possible with some redesign.)

That's all for now.

Hi All,
Update 4 Jul 24
Engine cover-internal details: building up the immersion locks from printed parts and pins:

Cover catch:
Rear cover-doc.jpg
This is a Sixth Scale Icon part. Needs to be etch-primed and epoxied in place before the weld detail is applied.

Engine:
After a long hiatus, I have returned to detailing the engine with the inertia starter:

and the generator:

Hi All,
Not an update but some news and a request for advice.

As you may know I have relied heavily on Shapeways for my out-sourced 3D prints in nylon, brass and fine detail resin. With the recent demise of this company I have been looking around for an alternative. Midlands 3D seem to fit the bill for nylon and possibly fine detail resin. They have no minimum order; are cheaper and, being UK based, have reduced shipping costs for me . :)

I am thinking of applying casting numbers to the domed cover on the rear engine cover and I am uncertain which number to choose. Whilst Tiger 712 (now 112 - Fgst.NR. 250031) has 33, Tiger 131 (Fgst.NR. 250122) has what looks like 77... any ideas or advice will be greatly appreciated.

Thanks,
Alastair

Did not know that Shapeways is no more.

I sometimes go here for a commercial print:

https://craftcloud3d.com/

There are some UK based printers to be found there.

Hi All,
Update 23 Jul 24
Rear Mudguard Stays
20240711_085457-doc.jpg
Stays finally installed. They have been in a bag for at least 12 months!


Rear sponson weld completed...
20240719_134508-doc.jpg
20240719_134539-doc.jpg
As with the front, I have filled the groove that I milled into the rear plate at the beginning of the build.


Engine and Rear Covers
Getting there...
20240714_070357-doc.jpg
Weld detail added and primed prior to fitting the locks. You can really see the difference between red oxide primer over Upol Acid 8 on the engine cover and just over raw black nylon on the rear cover. The difference will become more muted when the base coat is applied but will still be there to make the colour less monochrome.

I had some slight fit issues so decided not to fit the front immersion locks. The holes were modified by plunging with a 6mm end mill to leave something similar to that seen on Tiger 131.
20240714_070426-doc.jpg
Remaining locks and stops installed.

A close up of the locks...

Immersion lock
20240723_130424-doc.jpg
Hatch lock


Turret
I used a scissor jack to open up turret sides so that I could remove the front (CE1473).
20230824_162650-doc.jpg
I then milled 0.25mm (10 thou) off each interlocking face so that it could slide easily left/right in the turret wrap (CE2470). That way I would know that the fit of the wrap to the base (CE2472) was only governed by the flex in the wrap.
20230824_155631-doc.jpg
After priming the front, it was time to reassemble the turret...

First, the wrap was spread using my scissor jack and the front piece reinserted. I checked that it could slide within the wrap notches thereby ensuring it would not hinder the assembly. Next, the base was attached loosely using a M4 x 16mm cap screw at the rear.
20240719_165554-doc.jpg
Then three M4 x 20mm cap screws tightly secured the front piece. This provides a guide for the wrap as the parts are pulled together.
20240719_165335-doc.jpg
G-clamps were very useful in pulling the wrap against the turret base...
20240719_172252-doc.jpg
One side complete using two more M4 x 16mm cap screws...
20240719_180438-doc.jpg
Finally got it all back together...

The screws were removed, one at a time, and reinserted with red Loctite applied.
Now I need to design a replacement roof, which will be a steel laminate like that on the hull.


Engine Block
Decided to put some paint on the engine block so that I could get the rear mount and flywheel installed.
20240722_153435-doc.jpg
20240722_153702-doc.jpg
I am using Lifecolor RAL 7016 (Anthrazitgrau) over black primer. The paint seems to wear off sharp edges quite easily which is not necessarily a bad thing. Handling will produce some subtle weathering which I can lock in with a coat of matt varnish.

That's all for now...
