PHPaul Posted February 13 Posted February 13 My farm diorama is here. Don't know if the truck shows up in that thread so here's a couple of pictures. Thanks for your interest!

Thanks for your interest! I've always been amazed the level of detail guys like yourself are able to put into such a small scale. Even though they're not my "thing", train layouts and dioramas are always awesome to check out, and knowing someone put so much time and effort into build it is really what I find cool and interesting. I really got a kick out of the two tractors apart in the shop,and the inside joke among farmers you mentioned. The tree growing through the truck is a great touch, looks really authentic. Great work, thanks for sharing this. 1
johnyrotten Posted February 26 Author Posted February 26 Small update on this. I've got most of the new rear suspension figured out and built. Built a rear mount, spring and brackets for everything. Lots of little pieces had to be scratch built, I only snapped a few pics here and there. Now it's got a quick change. Thanks for checking this out. 7
Steve H Posted February 26 Posted February 26 Lots of nice scratch building there John. Looking good.

johnyrotten Posted February 27 Author Posted February 27 Got as far as I could on the rear suspension without the engine here, want to make sure nothing is gonna interfere with one another. Kinda at a stop till it shows up. Finished up all the brackets, tricky little things to build and not have fly across the room. Made the links for the rear end, nothing spectacular, still have to find some pins that'll look good to attach them and figureout the final length. Thanks for checking this out

johnyrotten Posted March 9 Author Posted March 9 (edited) So this was fun. Changing from the kit engine to the new flathead and the quick change required new mounts more clearance at the firewall, and a transmission tunnel to be made up. Everything on this frame is far from the stock location for the look, so that compounds everything. All while trying to not ruin the patina. The tunnel was purposely made to look like a hack job, remember a couple kids got a hold of gramps old truck. I'm gonna run some "welds" around it when I do the touch up to better hide everything. Should have done this from the start, live and learn. Thanks for looking. Edited March 9 by johnyrotten Spelling 3

bobss396 Posted March 10 Posted March 10 Great stuff... the making parts is where the fun is. I have a couple 3D printed QC rears I'm dying to try. I realize that I'm at the point where I need a mini lathe and need to get into soldering up brass and copper...

I thoroughly enjoy the scratch building, the soldering and brazing is something I already know how to do on a much bigger scale. It's probably worlds different at scale. 1

I thoroughly enjoy the scratch building, the soldering and brazing is something I already know how to do on a much bigger scale. It's probably worlds different at scale. I was certified for shielded arc welding at one place I worked at. I was a tattoo apprentice around 1980 and one thing I did was silver soldering needle bars. I worked in one R & D machine shop. We did all sorts of silver soldering, brazing, soldering on hot plates. The shop was big into waveguide construction for RF electronics. I Also prepped aluminum wave guides for dip brazing, which we sent out. I set up and ran the EDM machines yo make custom choke flanges. Made electrodes from graphite, brass and tungsten copper. So I think a decent iron and a hot plate would help me out with the models. 1

Absolutely, that's an aspect of building that interests me greatly. It would be a bit more familiar, I suppose. Awesome background you've got, I haven't had an opportunity to use anything like an edm, I do use our cnc plasma and brake quite often. Mostly I'm just In the field or at the bench, with the occasional cool job like inconel or monel valves or manifolds. 1

I started this before I joined the forum, I was completely ignorant to the aftermarket and the scope of my abilities. And this forum. I rarely would do anything close to this or what I've seen here when I was 12-13. 1
Jim Dodson Posted March 10 Posted March 10 Love the 'rot through at the front bottom corners of the cowl, very realistic! Has me wondering how to create the appearance of chicken wire and bondo repairs in scale... 0000 steelwool and GreenStuff?? neither smoothed nor finished LOL.

Off the top of my head, a fine wire mesh and a filler/putty would probably be the ticket. This putty thins with laquer thinner and is quite workable, It does skin over quickly. The rot is grinding out the back of the panel till its paper thin and poking through the front side. I used a very bright light and ground on it till it was almost see through. The grinding is a much larger area than the hole. I basically mimic what nature actually does to metal, there's always more than what you see. 1
Steve H Posted March 11 Posted March 11 Nice work on the motor mounts John. Love the weathering on this, very well done.

I worked on a lot of stuff that most machine shops never saw. We did a lot of real small machined parts, the techniques cross over into modeling, how the heck do you hold this? The smallest hole I ever drilled was .006" in copper. We had recurring parts known as substrates that were ceramic. Those required a .003" hole drilled on a precision drill press. I luckily never touched one. We did one huge project for JPL, around 1983. All made from cryogenics. copper plate. It was something for cryogenics. 1

I don't get into anything that small or delicate, a few years ago I made something for a local college, 3/32 blind holes 2.500 deep in copper plate. On a clapped out bridgeport. I'm not a machinist by any means, so that was nerve racking work. I have a great amount of respect for true craftsman in any trade or field. 1

Depending on the alloy of copper, it can be hard to work with. Electrolytic copper can be quite "grabby". One alloy I worked with was an alloy, tellurium copper. It wasn't wrought, it was sintered. Very free machining.

Some kind of thermocouple. "Peck" drilling it to depth. And this bridgeport is beat. Made the set up as ridgid as possible. I'm FAR from a machinist, but I'm not afraid to read up, self educated and learn how to do something. I've learned there's a wealth of knowledge available if you look for it 1
