    USS MONITOR SIDE LEVER ENGINE

    I know exactly what you mean, I can NEVER get those other two idiots to agree.

    18 Cylinders Isotta Fraschini (straight six-cylinder x3 )

    I've got no clue about what actually would happen with your new manifold design, but my gut feeling is that the 2 outside cylinders would be starved for fuel. Your carb feeds the center runner, which in turn splits and feeds the last runner between the 2nd and 3rd, and the 4th and 5th...

    18 Cylinders Isotta Fraschini (straight six-cylinder x3 )

    Soooooo....... When it first popped did you run around yelling "It's Alive - It's alive!", or did you just get a silly grin that absolutely refused to leave your face? Congratulations, this has been quite the adventure so far. I'm looking forward to when you can say it's complete and you're...

    Question about putting VFD on a step pulley mill.

    I always thought that unless the drive was specifically designed for it, you needed to de-rate the drive when powering a 3 phase drive from a single phase source. (That old divide by the square root of 3 thing.) But most likely that would be for a 100%, 24/7 duty cycle. It's probably...

    18 Cylinders Isotta Fraschini (straight six-cylinder x3 )

    If you're replacing pistons/cylinders due to overheating, that means the beast has been running long enough to overheat - right? Don't keep us in suspense, I can't hold my breath for much longer. Enquiring minds want to know, what's it sound like?

    Electric Starter System for Model Engines

    Brian: Would a 3 position selector switch work? You can get them in different configurations, spring-return to center, and maintained. Use the spring return side for your momentary run and the maintained side when you wanted it to run continuously. They'd also have the ampacity and voltage...

    Question about putting VFD on a step pulley mill.

    Ignator: Regarding the obsolete AB/Rockwell drives. I've been working with AB drives since the 90's. I've got the PDF's for most of their drives, including the old stuff. Let me know if you can't find a manual, and I'll see if I've got a copy of it. Don

    Adolf's alignment buttons? Newbie, never heard of them - explain please.

    1/3 Scale Ford 289 Hi-Po

    I've seen the halves soft soldered together before, but never silver soldered. I know Clickspring uses super glue a lot for work holding on a faceplate, and I think super glue is stronger in tension than it is in shear. The glue would have been in tension from the centers trying to wedge the...

    1/3 Scale Ford 289 Hi-Po

    I would have thought that the pressure from the centers would have wanted to split the halves apart along the glue line, like a wedge. Since it obviously worked what was your secret? Minimal pressure on the centers and lots of glue area? What was your backup plan if it had split?

    American LaFrance Steam Fire Pumper

    The pumper looks great. I love the pin-striping. But those horses standing there like that look NAKED - they need harnesses. (There, that'll keep you busy for a little while.)

    Lost 3D print Resins?

    Agreed, but as you say, a noble effort. I believe that the "ceramic" he uses for the initial coating is actually a casting plaster that is not intended for a burnout cycle. I'm just starting to get things set up to where I can cast small parts. Working on a burnout oven now, so I'm still just...

    Lost 3D print Resins?

    Foketry seems to get reasonable results with his Lost PLA plaster/sand mix process that he uses in his "18 Cylinders Isotta Fraschini (straight six-cylinder x3 )" thread in the Work in Progress forum. He starts casting at about Post #120-ish, and uses that process to cast the crankcase and...

    1/3 Scale Ford 289 Hi-Po

    Miss-read the 0.0005" height as 0.005" - my bad. (I knew it sounded too good to be true.) I may have to invest in some Poly-cast filament and do some IPA vapor smoothing on the printed pattern. The printer specs SAY it'll go to 0.05mm layers but I'm taking that with a grain of salt.

    1/3 Scale Ford 289 Hi-Po

    Thanks Terry. I'm thinking about casting some parts for some RC truck and construction equipment projects that I've got lined up as future projects. These would be cast using either lost wax or lost PLA 3D printed patterns. I was wondering if I could use your bead blasting process to...

    1/3 Scale Ford 289 Hi-Po

    Terry: Your CNC machined parts look like sand cast after the bead blasting. I've probably asked this before, but... What's your typical stepover and depth of cut on the final pass? In particular, the corners on the exhaust header where it bends after coming out of the head, did you do any...

    How not to Do Backyard Metal Casting

    GreenTwin: Don't know if you've seen it or not but somebody has done a frame-by-frame of the video you first posted, starting right before the explosion. I kind of wish they would have started a few frames earlier. Don

    How not to Do Backyard Metal Casting

    It's amazing how many people seem to have a death wish and are willing to court disaster in an attempt to get their 15 minutes of fame - and/or a Darwin Award. This guy should rate at least an Honorable Mention in the Darwin awards. He did at least have a leather apron and leather gloves on...

    A New Home for my Benz Engine

    Since all you probably want to do with this model is putt around a little bit, a straight axle will probably work just fine. Besides, there's an AWFUL lot of RC cars and trucks out there that are running with a straight axle instead of a differential. You can always build a differential as an...

    American LaFrance Steam Fire Pumper

    That's a nice small-scale professional looking plating setup you've got there. It looks like you're using an aquarium pump to circulate the plating fluid. Since I see a thermometer, is it safe to assume that there's also a heater in there somewhere? Do you do any plating besides nickel? If...
