No problem. Thanks for the reply.

Hi Ved, That's a cool little unit. I've never looked at an air engine before. Looks like Solidworks. Any chance you could upload a Pack & Go of the assembly? The assembly file won't work without the part files. File --> Pack&Go --> Save to Zip File Thanks... E

That's an interesting approach. Thanks for sharing that. I was actually thinking about using a similar technique with a U manometer to precisely measure the pressure differential on each carb's venture (probably at the fuel feed bar). Using water, or a material with a lower specific gravity...

Interesting story. So I definitely have my work cut out for myself

Thanks for the interest and comments. I completely agree that this a crazy concept. Running 8 carbs is definitely very complex. But having them independent is the only way I could think that this concept would work. I'll give it a go. I had thoughts of setting up the carbs off-line...

An interesting development in my intake manifold segment. Some years ago, I made a crude intake manifold and must have revised the location of the mounting holes on the heads. The hole locations on the heads did not match the locations on the drawings. So when I made my new intake manifolds...

Hi Editor, This is possible. However, the reason I chose this carb was for its small size. This carb is supposed to be good up to 1" bore x 1.25" stroke. I designed this engine with square 1" x 1" configuration. So I believe these should be compatible with this engine. Time will tell. It...

100% in agreement. Thanks for looking...

I did some machining of the intake manifolds and the carb mounts. These are both sides of the intake manifolds. I also spent some time machining the carb mounts. I had planned to machine these from 1/4" stock but didn't have any that was the right size. So I machined them from a 1/2" scrap...

Hi Retailer, Ha ha ha... You're probably right about the carbs. I was looking for a project to test the dovetail and work on the 4th axis. I thought it would look nice to have individual carbs. Earlier on my web page, you can see an image of a single carb and simple manifold. This is...

Late to the thread. But awesome job! It looks remarkably like mine (my own design). But being a gluton for punishment, I machined my block from steel. Looking forward to following the progress.

I too have used ER collets, especially in the lathe when I need to do more precise work on small diameters. I chuck-up an ER tool holder in a 4 jaw and then indicate it and center it very precisely. As for centering the work in the dovetail, I have a small spring loaded pin in the base of the...

As part of this V-8 project, I started working on a small dovetail vise that I could use with my 4th axis rotary table. The problem I had with the 4th axis machining was 2-fold. First, I had issues with clearance of the tooling on the 3 Jaw chuck. This required the tool bits to be extended...

That's a great machine for the task. I've needed to lap smaller rings for a work project. I built a small fixture for the task. But I know from first-hand experience that applying even pressure to all sides while doing this by hand, is tricky. It's very easy to end up with rings that are...

I've been a member for many years, following many builds. But since I have so few posts, mine are still under moderation/approval. So I believe that my reply was just delayed in this process. This milling technique worked well for the laser cavities. With my crude machining skills at that...

I used the technique that Brian mentioned, to mill an elliptical laser cavity. I made many cavities in this way. The largest used a 2" end mill and was about 6" long. This was a double ellipse, where the foci of each ellipse intersected in the center. This was to be used with 2 flash lamps...

Thanks folks. It's been a fun, albeit an infinite project. Foketry, it is indeed without sleeve. At the time I started, I didn't even think about a sleeve. It took FOREVER to hone the cylinders. Doing it again, I'd 4th axis the block from aluminum and sleeve it. The machining would have...

Well, after a long absence, I'm back to working on my mini V-8 engine. I'm working on generating some funds for more of the needed raw materials. But I have updated the solid model with my latest version, using an overkill 8 carbs (velocity stacks not yet shown). It's a single overhead cam...

In between projects, I decided to share some of the tools that I designed for my micro tapping, hoping to build up project budget. I tap a lot of little holes (#4 on down). I needed a some better tactile feedback and came up with some tools to help. I've tapped hundreds of #0-80 threaded...
