Hi folks,

No problem on NBC pack, for me if its modelled already then its just a question of loading it up into the printer and pushing print.

Thats what I did with the NBC pack, very little effort.

I haven't been able to print the accessories to the NBC pack as yet, work has firmly gotten in the way, but will do this week.

I will print out another NBC pack and put in the for sale section, as they seem to pop up unexpectantly.

Cheers
Andy

Hi Gary,

Your NBC pack below.

Printed as a kit, needs sanding and removal of support material around handle and clasp.

Will add a length of mesh to the kit same as the mesh i have on mine (none handy when i took the photo).

Its made in ABS 0.09mm layer height, with cooling on a heated bed......

It loves "Plastruct Bondene" and any acetone paints :)

Send me your home address, will do hub caps in next couple of weeks as i'm heading to Italy soon for a week (brothers wedding) so doubt i will get time to do before heading.

Cheers
Andy

Andy thank you,

Brilliant work & you saved me loads of build time, I'll pm you later today with my address. Also I'll need your PayPal email address, so I can send your fee.

I'm also really busy at work at the moment, Final Major Project time for the students. At this time of year I become one of their most popular members of staff, the workshop is buzzing. Four weeks to go.......then peace.

Must post some more Chieftain build Photos over the weekend.

Thanks again cheers Gary
P.S Rob has the Chally, arrived yesterday

Here's some update photo's of the Chieftain Mk11 as promised.

Haven't really done that much, still fighting my way though some problems with the suspension......but I think I may have just solved that one in the last hour. :idea:

In between I've had a go at some casting in low melt metal, wanted to re-make the idler arms on my M3A3 Stuart, this is my test tank for the Chieftain build. Anyway the 1st cast went well, 2nd cast ran out low melt metal. Back to EBay for more. So I have one metal idler arm for the M3A3 Stuart, ...may post some pic's of the M3A3 sometime in a different blog"

Now I know I can do it I hope to cast the Chieftains pair of front track adjusters.

Along with Chieftain suspension, M3A3 metal casting, I've done some paint work, haven't totally decided on the colour scheme. No MK11 Chieftains were in Berlin, last ones a few MK10's so that's out...., Bob started the Chieftain 900 in good old British Army Black & Green, or as I live so close to Salisbury Plan firing ranges (about 6 miles away) should I do the UK Land Warfare Centre scheme, similar to the BATUS markings. .....Your thoughts please.

Its looks like its going to have some or all green on it, so I did a test run, here's the pics

Sorry I haven't posted for a while, I've been really busy at work.

But after a visit from my mate Rob this morning & our usual geeky tank build chats over a cup of coffee, I've been inspired to do some work on the Chieftain this sunny afternoon. I've been outside casting metal front idler housings, I did a test cast for metal idler arms on my M3A3 Stuart a week back. Work very well, so I had a go for the Chieftain.
Here's some photos, need to clean up the flash from the casting & machine out the holes but they look ok & are strong enough to take any sideward force from track turns." I Hope" :roll:

Melting the metal on a gas burner

After heating ,pouring, & cooling they were removed from the high temp rubber mouldings.

You can see the flash I need to cut off, this can be melted down & reused.
https://lh3.googleusercontent.com/KFxJT ... 58-h643-no
After cleaning up, even had enough time to take the M3A3 Stuart new casted idlers for a test run around the garden. They didn't bend or break so all good so far.

It's just over a month since my last post.

Unfortunately this is a really busy time of the year for me & our final year students at college, I've not felt like working on the Chieftain when I make it home, & from past experience if your not in the right frame of mind " stay away from your model building" your end up rebuilding a half ass effort.

Well today I said my goodbye, wish them all good luck at their university's & sent them out into the big wide world. Apart from some paperwork. workshop maintenance & machine clean downs .. I'm Free :D

So with the workshop free this afternoon I set about having a go at spot welding the Chieftains front light bush guards. I've been carrying the measurements around for weeks but had no time to anything with them. I started with 2.3mm copper coated steel welding rod & a plan drawing on a pined out jig, so I could get L/H & R/H guards the similar size. Here's the photo's
https://lh3.googleusercontent.com/MaYr0 ... 06-h622-no
As you can see one guard was made before I remembered that I should be taking photo's, but you can see my roughly made jig.
https://lh3.googleusercontent.com/1tlLE ... 79-h673-no
This is the spot welder with adapted foot peddle so you can hold items with both hands
https://lh3.googleusercontent.com/BjtxT ... 97-h673-no
Guard number two, any excess bar is cut or clean up on the grinder wheel.
https://lh3.googleusercontent.com/JhkfX ... 97-h673-no
Completed welding
https://lh3.googleusercontent.com/iePgI ... 97-h673-no
Quite pleased with the result, but needs to be checked on the tank.
https://lh3.googleusercontent.com/GIhLi ... 97-h673-no
And the last photo after a quick sand blast to help with painting.

That's it for now, but hopefully I can do some more work on the Chieftain.

cheers Gary

A long time since my last update.

When its warm & sunny outside I'm out & about & don't like being stuck inside, so the Chieftain build gets forgotten, but I had a visit from Rob & Mr Bailey last weekend & they re-sparked by enthusiasm in the Chieftain build again. With rain & wind this weekend I've finally got back into the Chieftain build.

Mounted the new casted front idler adjusters, bolted them to a 5mm ally plate that runs across the front end left to right. Took a couple of go's to get the measurements correct, but that is down to a lack of modeling in the last 2 months.
https://lh3.googleusercontent.com/1ppbk ... 21-h623-no
Managed to finally sort out how to make the idlers adjustable for track tension. Sorry bad photo.
https://lh3.googleusercontent.com/qqCWZ ... 67-h622-no
https://lh3.googleusercontent.com/kNHND ... 67-h622-no
As per the real Chieftain track adjustment by screwing the nut on the idler in or out will tighten or loosen the track. " I Hope"
https://lh3.googleusercontent.com/x5rfZ ... 30-h622-no

I've trashed the earlier posted light bush guards, I decided the diameter of the bar was to small .. re-making them, also been doing so more molds items with my nephews ready for metal casting. I'll post those photos hopefully early next week.

Ok back on the Chieftain build again, after a good summer outside.

Now have a solid hull, as the front of the Chieftain is now fixed in place, with all the lifting & towing eyes in place. The front lights are in position ready to be wired in, & mounted, just the bush guards to go on.
Front idlers adjusters are mounted on, just a bit of detailing to do. And started work on fitting bearings into the idler wheels, ready for the work on fitting all the suspension & road wheels. Plan is to fit idlers, then sprocket drive, when that's in the correct alignment, run a datum line front to back to get all the road wheels suspension in line so hopefully the tracks run straight. Here's some photos of the work so far.

Infer red lights in mounted, & a lick of green paint.

With some lights fitted it started to look like a Chieftain
