I have locked myself in to staying true in principle to the Detroit Diesel as much as possible. The wedge is less untrue than any electronics, LOL. Plus, I think governors are pretty cool. Yup Exactly! Just looked thru my old notes (I try and keep a project notebook) and had calculated that...

Mike, (I am a 9 finger, too, LOL) The bleed method sounds good. Mine currently has no good method to bleed and it is a major pain. Re: the gear pump. Something I have already tried and it works for the low pressure fuel, is to use a single piston pump driven off the crank and synched/timed with...

I am glad you are online! I haven't been this excited about the project in quite a while and I think this is a major milestone. All of the "golden arm" adjustments and fits are gone.There are still a number of potential leakage points but they are mainly housekeeping issues, not functionality...

@The Ignoble Troll It is a bit serendipitous that you started this thread last week. I had set the diesel aside and was working on the Arduino Hall/Optical tach. Your post pulled me back to the diesel and I had to finish up a few things on the injector, coincidentally, incorporating that it...

FindHansen has at least one good YouTube video (among his many excellent videos) demonstrating the wedge adjustment for fuel volume and for timing adjustment. I think it was in a video of his dark green vertical diesel where he has all of the parts laid out and explains them. I am not sure, but...

Excellent discussion, everyone! I am still in the unit pump/injector wannabe group and have at least a half dozen versions of the "so close you can taste it," category in the boxes of failures. Designing to a minimal number of critical sealing surfaces seems to be the most workable goal for...

@ninefinger I agree with Everything you said. The fuel injection is the evil devil in model diesels. The injection system, whether it is a pump-line-injector, or pump-line-solenoid injector, or a unit injector of pump and injector in a single unit, that is the real bugaboo. A few on this forum...

The solenoids will take some experimentation to find out how best to extract the power you need, in the form that you need it to be in. Sometimes you can start the solenoid farther out of the coil and let it pass thru to gain velocity for an impact, using the laws of conservation of energy and...

Some interesting concepts. (BTW, I work on and off on mine in the background. It is still moving forward.) I agree that a cross head would be needed with the long stroke to bore ratio, but that would be very cool. The electronic injection intrigues me. If you can indeed get the 1mm plunger to...

STATUS UPDATE -BOTH HALL AND IR TYPES We had some snow here and I had to get 2 generators running and one snow blower working. None had run in 2 years. (Yes, yes, I know. :mad: ) The gnerators are running but I am struggling with the carb on the snow blower. Then I had some outpatient...

Very slick way to work around a problem!

Heading back toward the original intent of the OP, I started amassing my tools in my early teens. So what can you afford at that age. I remember getting a handy sized Stanley straight screwdriver. The flat tip was about 3/16", and the OAL was about 10". Black and orange fluted handle. Easy to...

@Gordon , can you seal it well enough to put it under water to look for bubbles?

Wow, I am loving all of this "sentimental history" that is coming out. A lot of pleasant memories, I bet. When I was a teenager, we built a smallish "nice" workbench with a top made out of clear fir 2x6's and held together with screws, not nails. It was a big deal. Do all the crappy dirty jobs...

We had one of those when I was a kid. Only used it on projects that I didn't mind getting blood stains on. 😖

Agreed. Take a look at Craigslist (or facebook market place) and you can see the people who place extra special value on something just because it is theirs. My wife is a smart shopper and always keeps an eye open for the local Facebook Buy Nothing group (free give-away stuff). She noticed one...

I agree, gents. Modern mass production has made inexpensive tools widely available and only businesses and serious hobbyists are willing to pay for the premium brands. And lets be honest, if you are driving more than 2 screws, which do you reach for first: the hand screwdriver or the...

Good stuff. It's been a really long time since I've seen one of those Bosch jig saws, but I know that blue color. The newer "disposable" tools definitely serve a purpose, but I am glad that there a few manufacturers that still build durable tools. I have a 3/8 Holeshooter but not as old as...

Here is one that I like that allows you to get data for any custom thread size that you want. I do a lot of oddball size threads in the ends of tubes, with matching plugs, so it is very handy. http://theoreticalmachinist.com/Threads_UnifiedImperial.aspx It shows every detail thread dimension...

I was making coffee in the kitchen this morning and was absent mindedly looking at the blue Kitchen Aid mixer on the counter. "Darn, how old is that? 20 years, 30 years?" When I was younger and had lots of ideas and enthusiasm and energy, but no spare money, buying the right tool for the job...
