Hi Bob
Nearly bought a Sherman before going for the Panther G about 15 years ago when Mark and Gill
just were taking over the company.
Wish I had done as they never released the model again in that set up.
Dont like the look of the firefly.
So part of the reason I bought my Lee as its the same sort of footprint.
Love the parts you are making keep it up.

regards

Derek
we must stop making stupid predictions

Phil, Derek, Simon - thanks for looking and for the encouraging comments. Its great to see some progress on this sorely neglected model.

Some more bits added. Got the Lazy Susan bearing fitted under the deck plate. Very smooth rotation now, just need to fit the tooth ring for the drive motor:
Image

Close up of the mounting block - spacer. Screw is M4 from below. The brass block spaces the turret and provides 3 location for mounting. Only 2 location are used with wingnut for holding turret on. The front acts only as a pin since the hole is directly under gun barrel (cannot be reached easily).

Image

Inside turret - 2X M4 wing-nut to hold turret to ball race.

Image

Made a new CDR's MG mount from brass to replace the kit part:

Image

Decided to improve the look of the hull MG mount by removing some material:

Image

Made some periscope covers for the front locations on sponsons. Will 3D print some scopes for the hatches for driver and MG gunner. Haven't decided whether to keep the kit white metal drivers hatches or print new ones. :roll:

Image

Hopefully more to see and show soon.
Best regards,
B

Hello AT forum. Posting a little more progress on Sherman detail parts. I've been printing some of the smaller detail parts with pretty good results.

Gas caps of all kinds. Experimenting with printing text on the parts with good results.

Image

Designing the M4 air cleaner boxes for the back end. The detail bits will be printed. The square box will be Aluminum tube.

Image

Took a crack a designing the drivers hatches. I like the kit metal ones, but they need quite a bit of parts and detail added, so may use these printed ones. If I break one, I can print another.

Hatch with my lower periscope installed:

Image

With upper periscope installed:

Image

Image

Image

Image

Test printing some parts from Shapeways in Brass. We'll see how they come out. I can make the Periscope guards - they are just very time consuming. Always wanted to try their printed - brass lost wax process. Note the rear lamp housings have an extra pin for mounting support - the original housing only mounted from rear. I didn't want these to be too fragile.

Till next time, stay safe everyone.

Hi Adrian,
Thanks! I think so too. Really nice on the Elegoo. Layer height 0.04mm. Text height (from or into surface) 0.25-0.30 mm, Text size 1.5 - 2.5mm high.

Getting ready to try the water washable stuff on the next prints.
