Thank you for the compliment Truckmaker. It really is a blast working with brass. All I can say is try it! I'm sure it will hook you. As for smoothing tacks and joints, I use many methods. I use heat to smooth as well as a stick for lead. For the most part though I scrap and file and sand. It's slower, but using heat on larger joints will work against you, too much heat and your parts start to float out of alignment. It sucks when it happens, and can quickly turn you from working with brass.
And now.......
Today's progress

This is the cardstock side I cut, and scribed onto my brass sheet

I didn't cut the brass near as high as my cardstock cut out because it seemed to high to me. I also added 1/8 or 3mm to the top and bent it

If you look closely at the seam, you'll see the bend at the top, this bend will keep it true to the top, and keep the warping to a minimum

I failed to take a picture of the grill reinforcement as I was doing it, it's sitting in the middle

Here's how I installed both sides, a couple clips and work fast

And here's the almost finished product

From the back

I decided I should mock it up a bit to see if my proportions are correct

I'm really happy with the look

And I thought I'd put a stack there to get a feel for the progress

I'm liking the look
Next up are the fenders, and the rear reinforcement, then the hood hinges. I'd like to put the old style 3 piece steel wheels on this truck to give it an old school feel, does anyone know if anyones making such a wheel?
I hope you enjoy
