BMW v8 engine coffee table project

Super awesome man! Keep it up!

the stock stamped steel ones? they are pretty ugly, some of them are even T-shaped leaving the head. have any pictures, anyways? i'm curious if m62 looks much different than m60.

thanks for the offer, but I'm going to pass. i mostly hate that left/right are not symmetrical, but those stamping edges, wow it makes them look so cheap. what are those called, "hemming" or something like that?
Dan
-
ah i see. unfortunately I cannot weld or machine anything, so i'm limited on customizing stuff like that. yeah they are definitely dual-walled, thats why they stamped them instead of just welding or casting.

got the main bearing caps painted and the related hardware cleaned/polished.
also, my 1.75" 6061 aluminum tube came in for the 'headers'

more work done on headers:
finished the flanges
wood filler used to get the grain/imperfections hidden before painting. before on top, after on bottom.
to cut the tubes, I don't have a miter saw, or a table saw, or a band saw, so i made a little jig for my circular. fyi, diablo circular saw blades are the shit. i've been cutting soft woods, hard woods, and aluminum on the same blade for YEARS and its still sharp.
rough cut done
tubes filed, fitting and glued into the flanges. all that's left is to make some 'simulated' welds and then paint.
also started on the injectors. they were a bit crusty, and i want to use them to bring a little color to the whole motor, so they will be painted BMW blue.

In for "simulated welds" im envisioning some sort of putty molded into the gap
yup, been experimenting with what material will work best. and studying 'weld porn'. silicon sealant is too sticky for shaping. wood filler/wall putty is too gritty. going to modeling clay next.
don't think I'll get quite this perfection, but its what I'm shooting for, if possible:

i searched for a long time to see if someone had done this full scale and couldn't find anything. where did you find that?
and thanks for sharing, that is a great place to start. the only thing different will be working in a corner, versus a flat surface.

not a bad idea if I could find such a thing. makes me think of trying to cut the clay into half-moon or disc pieces (like using cookie cutter) and pressing them in place instead of making a bead then shaping it with a tool.
Dan

You can easily make a tool to do the pattern as well. Cut the half moon shape into any flexible plastic thing. A spatula, bondo spreader, etc.
-
so, i tried a few techniques and the best turned out to be rolling the clay into same-sized balls (ha) and then pressing them individually into place. it was the only way that really worked with the fact that it was a T weld on a curved surface. i also tried to leave the edges over-exaggerated in case shrinking or paint layers hides it later on.
air dry clay
pressing the pieces into place one at a time
some finished tubes
