MRS 3D model

[Mark Heaps]

The MRS red beam was selected manually for a few seconds

For a few seconds ? That may be what the book says but momentarily was my experience.

Monitoring the radio net on ranges with multiple regiments that I was attached to, Chieftain, Challenger 1 & 2, QRIH, 14th/20th, QDG and RDG, the gunners would transmit "MRS-ing now" informing the commander of their tank plus the rest of the tanks on the net that they could not be observing the front, followed almost immediately by "Back up" meaning back in action.
They would depress the gun to the required alignment marks, switch on the light source, observe its deviation, switch it off, elevate again, and then manually adjust their point of aim accordingly rather than adjusting their sight.
Ranges always meant long nights for ECE´s like me as the faults would only be reported after the days firing had finished. The tank crews were damn good and would revert to rev modes if some system stopped working. My job was to give them full systems for the following day.

a little bit of clean up is all that is required.

Steve, you could be correct, but I suspect it would require a lot of patience, which I might be missing.

Hi Vince.

All I can say is very well done. I'd love one, but as I have said previously I am not at tall familiar with 3D printers.

Cheers

Not to worry Charles, I may be able to help out with Vince's fantastic sculpture, I know a magician, no charge.
It'll look good with a red dot appearing from it.

I think it's finished. Still need to run a final test print but not sure if I will be doing it today.

Vince

[Vince Cutajar]

I am calling it finished. Used a little sandpaper for a little cleanup. Still not up to scratch but better than nothing. Ideally a liquid resin printer should give better results but as I do not have one I did not try it so can't really say how it will end up.

Parts on print bed. As you can see the top cover and thin side cover were printed vertically. They gave me a lot of trouble and at least with my printer printing them like this gave the best (not perfect) results.

Parts on print bed. The bottom part is the front part (hood) of the MRS which has to be glued on.

Not up to scratch Fan bloody tastic I'd say, A month's work just to get close to it, a pack of files and a pack of those silly little plastic letters that cost an arm and a leg and are probably(2mm type) obsolete now.
Many of which end up flying across the room and end up in the hoover bag.

[Vince Cutajar]

Thanks John for the nice words.

Forgot to add that those were printed with a layer height of 0.05mm

[Vince Cutajar]

Wife in Cambridge and I'm alone bored minding the cats.
So i thought up a crazy experiment. Nothing scientific mind you.

I made another two MRS prints. One with a layer height of 0.1mm and another with a layer height of 0.2mm.

The one on the left is 0.05mm layer, middle is 0.1mm and the one on the right is 0.2mm.

For sure the one on the right is the worst one. I am not sure about the other two. Some parts look better in a particular layer height whilst others are worse in another layer height.

So I learned that maybe printing different parts in different layers could be helpful.

These are Vince's beautiful sculptures when printed with a resin type printer.
There's some fine detailed small cover disks to be fitted to the armored visor at a later date.
This amazing work done by Vince and Mark, I had nothing to do with it

OMG, if I'm allowed to say so myself, those came out really well. What a difference a resin printer makes. All those pesky layer lines gone. All those minute details came out perfectly. You made my day John.

Fab work as ever Vince

[Vince Cutajar]

John
If you find traces of unwashed resin clean that area with isopropyl alcohol.
If you feel the surface a bit tacky put it under a UV light or in a sunny spot outside to cure that area.

Vince

[John Clarke]

Their frighteningly good Vince and better in real life. Mark says he washes them with alcohol, then UV lamp and finishes them off with sunlight for day or so to harden. The surface marks are not indentations, more like light stains from the process.
Their heavy because their solid, but not as heavy as solid resin cast, detail is mint.
Magical

Work of art Vince and John, worth all the hard work. Fantastic collaboration all round."MRS IN....." "Fin tank ON..."
