another question for mad ... the diameter of the linkage cross bar - appears close to 1/2 inch and the diameter of the steel fuel line - appears slightly more than 1/2 inch nominal outside dia - 5/8 ??? just made the forward facing fuel distribution block ... thanks in advance

How do you think it would handle?

Gotta. Start somewhere... .020 x .156 evergreen strip ...

Thinking about an engine swap in the Cooper. What do ya think ??

Thanks terrifying ... sigh .... scalpel ... suture please ... Dog Fish Head ....

Mad. On your 8th sc blog there are some great photos of the brackets that support the rod that articulates the fuel injection linkage. Could you post a photo of the fuel block sitting in the center of the assembly - and a photo or drawing of its attachment to the middle bracket and or the top of the valve train cover gracias in advance ... and if anyone reading this hasn’t yet seen the 1/8 build on the big boys blog - stop what you’re doing and go to the big boys section and you’ll see the posts there ...I’m referring to the posts on the Ford soho indy engine ...

I knew I shouldn’t have said that ... so I managed to make one before running to the cooler ... evergreen I beam filed and sanded and sawed. With a .012 drilled bolt hole and a piece of .012 brass rod and a .020 r b motion nut. Momma Mia l forgot how miserable these things were ... I’ll be able to knock out about one a day ...

Scary nice

I know that you’ve been pondering the design of those headers ....

After an alcohol wipe, some toothpaste and an old toothbrush - both the headers and the engine block are ready to go. Once you cleanup the back of the engine the detail on the engine mounts is very good. Despite the fact that the engine is “printed” from this projection ...

Thanks to mad for the commentz. Sunlight! Let’s see. I live in florida maybe see if I can find some of that ... ive tried to sand blast in the past. Tough to do here in the humidity. Never found a good way to set up the equipment. Gonna need a bigger work shop ... but thanks for: A. answering a modeling prayer ... and B. sending me down this rabbit hole ...

Lastly - the MPC 25th scale Gurney ‘68. Eagle kit headers ... Well, they tried ... You will notice that the header flanges are about the same distance apart left to right - and about the same length. I think that the mad mike printed 25th scale headers might fit onto the gurney kit engine. That’s the next lab experiment ...

The next victim is the header casting in white metal from the English Finecast 24th scale Indy Lotus. I love these kits they make great curbside models. Their dimensions and shape are very good. But about those headers...

Now a look at their ancestors ... first up is the IMC Lotus 38 25th scale headers. We’ll call this part “junior”.

The 25th scale headers are on the left and the 24th scale are on the right. There is a slight difference. I think these pictures will show this ...

So lets do some more obsessing... these are three main components with a minimum of clean up. The exhaust tip fits snugly into the collector after cleaning the tips

Yup. I’ll post a group picture of the exhaust headers w the corresponding lumps from the lotus and eagle kits. Later tonite .... since - like most of the rest of us - you’ve got nothing but time on your hands .... would you like to create a demo header tab in brass and post the results. I’ll try one in plastic ....

Gonna try something milder first ....

There is a film or residue on some of the parts - like the exhaust headers how would you suggest that I remove it ? mite try toothpaste and a toothbrush. Suggestions ?

posted the photos on fr the I phone but it is easier to tap out my thoughts on a keyboard So: Mad Mike is the creator of the Ford 289 indy engine that I wrestled with on page 2 ... He has now drawn and printed nearly all of Ford's mid-late sixties racing engines - mostly in 24th scale - some will fit with mods into your existing kits - you name it some will not - but these are worthy builds as stand alones …. in fact, this - as Pico reminds me - is the brave new world check out the Hewland script and badging on the back of the transaxle casing - yikes remember how impressed we were when we saw this on a large scale kit - this is 24th scale ! and I have made no effort to clean up the parts - how great will these look once and cleaned up and with some paint on it ? actually Mad posted a picture of his 24th scale build on the blog in the Big Boys Section on the 1/8 scale Ford Indy DOHC model that can be found back in the December postings - worth a look there will be a lot of clean up on the back side of the engine - from which the part is printed - or "grown" that's okay - the missing casting features can be added by the intrepid engine builder ... Now there are some scale compromises - but hey - we've got to fix - or ruin - something - right? the 24th scale exhaust headers are printed without the fasteners at the collector pipe joints - these thingies are called "header tabs" according to my google machine ... we'll have to make our own …. - but consider how much better this engine looks with scale accurate exhaust headers compare this part to the sad lumps that were created by AMT, MPC and/or Finecast when the Indy kits were first created in the seventies. not their fault - back then the defense department couldn't have done this either the 1/8 scale engine was printed with the a wonderful fuel injector link assembly that flies across the front of the cam cover - probably not do-able / printable in 24th scale - but Query Mad - when you did your assembly on the 24th scale prototype - did your print your assembly or fashion and assemble it from brass etc ? the valve covers have the FORD block letters down the length of the part - accurate for the later DOHCs - particularly ones used by AJ the Lotus Indys and the Gurney Eagles had earlier engines without this script - so those wanting to build an early DOHC engine will have to make this change - or perhaps pirate the Gurney Eagle kit valve covers for the 25th scale engine kits - just sayin' I've got some more thoughts on where or how these engines could find their way into a few kits - that's for a separate post - but assume that a 25th scale engine kit might be the answer for a correctly scaled 24th scale Indy kit wondering if the 25th scale engine might squeeze into the 1/25 '68 Gurney Eagle Indy kit - it mite the 25th sc Lotus 29 Indy kit ? dunno afraid that the 25th sc AMT Lotus 38 kit is a lost cause …. much too small … long post - I get paid by the sentence - right ?

Thank you for your concern. But my mental health is fine - l lost my mind years ago ... Randy at Model builders’ Warehouse will happy to send you some . However, there may be a small charge ....

I’m going to stop now. Let me know when your eyes stop watering ....

Some more ... if you are drooling on your i phone - be sure to clean it thoroughly before you text your response. - as we must maintain sanitary posts ...

More shots of the 24th scale engine ...

Oh wait - you want me to build these ??? On the left is the 25th scale ford DOHC engine fr mad mike models on the right is the 24th scale engine with some parts removed
