With the cap on [ATTACH] And eyeballing TCD, it should be 1/8" pop-up and that looks right [ATTACH]
Its a resin printer not filament. There is a liquid tank and a UV projector cures the layers into shape. Prices are lower now but a couple years...
I "honed" the big end (aka ran a flapper wheel through it) to ge the bearings to sit in right.....hmmmm...that's not right and the chambers are...
This is an 1/8" pop-up, radius corner, upper ring lowered to be 1/4" from the top of the bore, pin moved for the longer rod. A little porky at...
The new rods are 7.75" long, stock is 7.4", so the pin moves up 0.350" in the new piston....that will change the side clearance a LITTLE...5%ish...
The new rod looks more proportional to the piston I think [ATTACH] Then worst case clearance to the block it like 0.060-0.070 (with a feeler...
The rod looks like its printing fine but the cap failed and will need to be reprinted....so it goes. I do want to see the new cap but its not...
The block has a sort of round clearance ground in that kind of matches the big end of the stock rods, so that could be reshaped to match the new...
I slimmed the beam a bit so it will fit better and a few other changes....630g now, just 8g over stock rod weight. Just about time to place an...
It was Lincoln night. I fought the damper off the crank figuring it needs to come off and it will be lighter. Then cleaner up a piston and...
I decided to print the rod to see it but mostly I want to drop it in the block just to be sure but that will be another day. [ATTACH]
Its mostly a public service notice. I couldn't find anything I liked spec or price wise so I assume others have the same issue and its pretty...
This prototype just arrived. This particular unit electric power steering unit is going in the ferrari (to replace a fiesta unit I broke :( )but...
690g now and the beam has about 15% more meat than the scat [ATTACH]
100g was exactly what i was thinking......
I saw a single scat flathead ford rod on ebay and bought it to see what is acceptable. [ATTACH] [ATTACH] [ATTACH] [ATTACH] If I'm being honest...
do you have a pic of the car somewhere you can share? :rolleyes:
I've always seen the H beam rods a amazing....I remember seeing them as a kid in car magazines but yeah, it turns out plain old I beam are...
back to rods. The first place to actually give me a quote doesn't really do design so I need to model up what I want. I grabbed a junk...
You might be right but its the journey I enjoy anyway so it doesn't matter. Plus the no questions asked budget I agreed with my wife is $250/mon...
I fear I've already been that aggressive. I drew it 28" and the front is curved to look better with the curved windshield....so just under 26" at...
I haven't gotten to worrying about feet or really width, its more the profile I still don't think I love. The old roadster/speedster stuff in...
The delahaye stuff is good looking for sure. The low and min-engine nonsense I've gotten stuck on makes the proportions very different and that...
Oh the poor thing! Have you got a home lined up for your build(s) or a timeline in mind? I really don't want to be doing this engine just yet...
Talking about design choices and compromises....this is a shared journal V12 so to run smooth the angle must be 60 degrees. The F1 world figured...
You hit the problem with design work kind of right on the head......there are 1000s of choices that will all work fine and that makes picking 1 a...
CAD model of the 42up Lincoln rod, but stretched to 7.75" long and small end width cut to match big end. [ATTACH]
Those are 90deg/cross-plane crank V8 issues where its all done as sets with bob weightes....no bob weights used/needed to balance these engine....
I see the word custom and start thinking ...yeah, it should be custom! Why is the small end so wide? and why is the pin so far down the piston?...
So it looks like there are 2 rods designs. https://www.jalopyjournal.com/forum/threads/lincoln-zephyr-flathead-v12-reference.329363/ CC= 7.400...
