Here is a photo with the lights out, maybe you can see the very small holes in this photo alot better. I will be drilling these out in the stainless steel pieces. plus doing all the bends at the marks and cutting areas out

"Any feedback on the project is always welcome, even suggestions on it are also.  I hope you enjoyed this update. "

 

 

Ok, you asked for some feed back, well I think this is just terrible, the frame is a mess, from someone wanting to make a accurate model, using a shelf bracket is far from that, and steel at that, cutting it with a dremel and marking with a marker pen is not an accurate way to build a frame, nor is it reliable for consistency, 

 

Suggestion, I suggest that you throw the steel frame away, and start again with sheet brass, brass when treated with the respect it deserves can be built far nicer than any other material, it has the strength and lightness to out do plastic, as well as steel, and it will give you a better finish and far easier than trying to weld a rusty shelf bracket, but the key is, it can produce a far more accurate frame than a steel  shelf bracket, for the amount of time and effort that you have put into this you could have had someone fabricate the 2 C channel sections for you

Yes I did ask for suggestions, but may I ask you two things.. what photos are you looking at the old or the new? Shelf framing? 2nd, you even told me before (last summer) to go with something that is uniform all the way and will hold. The steel is, it's uniform on all side, brass is a soft metal, the different between the two is one you can only weld to and the other you can only solder to. If I start with sheet brass, how do I know that it will be uniform all the way through plus have the drop down in the front like what this project calls for? It won't, the only way to get that in one shot would be plastic or resin, cutting the channel is the only other way to get that drop down, unless you used a machine press with a die. About the finish, the whole thing will be painted but I do understand where you are coming from though. Plus when you said rusty, you must be looking at the old photos from last fall, because the new ones doesn't have no rust on them. If your looking at the new ones the welding areas is not rust and those things have been clean up.

Have a read here, read all the 153 pages of this tutorial, by one of the best brass builders

 

http://www.scalemoto...ld-journal.html

 

And another exceptional brass build

 

http://www.scalemoto...8-th-scale.html

 

 

And this will show how brass is best worked with and it capabilities read all 68 pages by a hobbyist and see the results he gets

 

http://www.scalemoto...al-mark-ii.html

 

and another one just to get the picture

Hi you all, well I been busy at this project for a while now. I had a jig issue and took care of that. 

 

I also want to say "Thank You" to Tony for the links he took time to gather to post to help me out more with my brass work skill building. Those links will help me out a lot in due time. I'm still reading on a few of them yet. That is some very good info. 

 

Getting back to the project at hand. I am going to mix materials on this project. But first thing first. I want to get the frame of the chassis off the ground.. my main focus is really on the chassis kinda. 

 

I'll let the photos talk. 

 

I started about a month ago by cutting a strip of stainless off, to use to start making the front leaf hangers, rad support, hood hinge.

1002371_10203926183419238_72383064594028 

 

 

Once I cut the piece off, I started to use the smallest dremel drill bit I had in my small pack.

But something to me look strange, so I took it outside to see since the work area light was acting up.

 

Sure enough, the one side was okay, but the other side was not, some how afew of the holes was out of linement.

10291714_10203926187859349_3523152603308 

 

So I went back to the work desk, and with having the old negative yet in the desk top, I started to draw it back out. All the holes was there and also the markings.

10151764_10203926189579392_1968306827870 

 

Now with the new drawing, I used a 1mm piece of no trasspassion sign that was plastic to make a new jig.

I glued the pieces together with superglue (Crazy Glue) to make both pieces at one time and also to get the holes all the same.

Marking the bend marks all the way across

The holes all look good to me now this time around.

Okay, after a few days. I did get the hard part almost done now. 

 

1920064_10203955671156413_87995753781114 

 

Now was the fun part, cutting the scribe line to bend the parts at. The white strip is a guide line for both sides

10308243_10203955674996509_4041265495524

 

Here you can see that I have the pieces apart.

10153173_10203955675876531_6176160020765 

 

Here is the first one bent into it's unit, one to go yet!

Are you going to re-fabricate the hood and cab out of sheet metal also ?
