no problem silentbob.
if it were not for overlander, thorsten, killer and others who posted i don't think this would as feasable for people who are attempting these little (big) projects. or atleast feel confident that we could. i've wanted to do one ever since i saw the first post and german sites a long, long time ago. i always thought it was only possible for experts and the such. (not that i don't think you guys who have done one aren't) seeing others do it and be so helpful to us who are trying has convinced me that i can. thanks guys, and good luck to everyone else trying like myself. can't wait to see more completed projects. who knows, maybe if enough of us have them, tiny will start a categorey just for us 1:87 or ttt people.
- i'll have the link up for you sunday night. i expect to get home after 10pm.

overlander-
nice pictures in your mzr album! i keep checking it every so often. i suggest others do as well.

Micromark also has a decent selection of small screws and whatnot:

Little bit cheaper than hobbyplace on a per-screw basis. Also decent for tubing and the like.

thanks for contributing the link. the more people contribute, the better off we are.

better keep the total below $30. $6 is reasonable sh, but almost $10 for total over $30 is a bit steep. especially if you order more than $30 in screws and stock which can be done rather easily. i spent over $20 at my lhs just on brass stock. i don't think i'll be going back. Convenience has it's price i guess.

personaly, i get frustrated by sites without pictures. i like to be able to see what i intend to buy, even if it is just a drawing like on hobyplace. i find it much more helpful than just an inventory spreadsheet. especialy for those like myself who, if not for this project, would not know the difference between a fillister head and a hex head screw.

hobbyplace does have a good selection of brass stock as well, tubes, rods, angles, strips and sheets. a limited selection of aluminum.

Arch,
I agree with you about pics in web advertizing.

However,
If you get microMark to send you a printed catalog, your miniature modeling experience will take on a whole new meaning. Micromark is one of the best suppliers of miniature tools.

I'm stuck in a hotel right now. At least I got broadband!

:ö: an aditional tip or advice to those who are just planning to make their own 1/87 TTTT... "don't forget to insulate those exposed battery terminals" !!!, i know, this is common sense but, i think i forgot where i placed mine

, co'z "i did not insulate those battery terminals"

, what happened was i was trying to climb a foot high homemade dirt hill, the hill was so steep that my truk rolled 5 times all the way down, this is a common incident, but this time, when i placed the truck back, it was not responding to my command, then, and smoke comes out at the back of the truck!

... i opened the back, battery was hot, and same goes with the reciever

,...

solution? i suggest you cut a small circle out of an electrical tape or masking tape (same circumperence as your battery) and place it on the terminals after installing all the wires on your battery! this may prevent unnecessary short circuit !.

1/87 8 x 8 truck project update:
steering knuckes... damn! this thing is giving me a headache!, and pushing my patience to the limit!

... good news is.. i'm nearly finished with the first front axle!!!.. i wish i could bring my gadgets to my work and continue working on this, man my day-job is a big hindrance to this project!!

Arch2b,
Yeah, I ordered that from the link you posted a few weeks back. It is on back order. They also make a 6x6 I think.

Good advice Killer

!!

A follow up to Killer's advice on insulating batteries.

I had a problem with my speed control touching my brass frame that caused a short and blew up the control. Also, my batteries in the cab of my UNIMOG have to rest right on top of the frame and I knew this would cause an explosion

I used the infamous [b]PLASTI DIP[B/] to insulate all battery ends and certain circuit boards. Actually it is a product called Liquid Electrical Tape from a company named Starbright (they make cleaning products for my boat too). It is esentially the same as Plasti dip. Just paint it on and let it dry completetly. it might take a couple of coats, but dont make it too thick unless you have a lot of room

My UNIMOG was so crowded that even a thick coating would have taken up too much space.

Hi,
even this is another reason to use painted copper wire (like use in relais and transformators).

If you use a very thin coper wire, so in case of a shortcut, the wire will be demaged, not the circuit.
You can see the shortcut by the colour from the wire (or the missing wire, if the shortcut was a fatal one)

Another question:

Whats about the 8x8x Tatra??? I always saw the pictures of a catalouge-model and not pictures of your truck?????? ;-)))

I'am still unable to build a powered steering axle and I want to learn to build one.

best regards

Thorsten

:ö:

here is a drawing i made on MS Paint (sorry i don't have an AUTO CAD program

) on how i made my universals for my front tires to be able to drive and steer as well ...

this will be an easy task if you make it on an allum tube, you don't need make part no.3 you can solder the connecting rod in the middle which will act as your cross joint(?)..

if you got any question, i'll be glad to answer it!.
