    18 Cylinders Isotta Fraschini (straight six-cylinder x3 )

    /|\ Agreed ! Quiet an undertaking with impressive results. Not without it's problems and you shared them all and overcame them. Very impressive ! I have been following and very pleased to see it running. :) It has a great sound. Well done, nice job and thank you. Scott

    New "Project Log" forum WHY?

    I was half tempted to make the first project log with glaring incorrect information and stolen images from other members claiming to be mine, and detailing terribly dangerous machining operations. Which nobody could comment on. Report it sure, but hey it's on the internet it must be true. But I...

    What is your purpose in getting into the hobby of building model engines?

    Minh Thanh I think you made a mistake in combining the off topic posts. I think that it may have been better to move them all to a separate thread ( noting that in this thread), thus preserving your original post. Which I found interesting, the off topic drama, not so much. I do understand that...

    Mastiff lc mason engine REDO .

    Hi Minh Thanh I concur, drilling a bunch of small holes sucks! Several of my products have small holes. I am calling .0635" a small hole. I have drilled many thousands of these holes over the years. My advice for your upcoming hole jubilee is to first, make a fixture with a hardened bushing (...

    Total Eclipse April 8th, 2024 - Arkansas

    If I stay at home we will get 3 1/2 minutes of totality. Not too far off of the centerline. But the local weather folks say historically that is an overcast day :( My location circled in red Scott

    Strange reamer designations

    A friend of mine used to drive a garbage truck and was a real "Picker" if he would see something that looked fairly decent he would keep it and then have a big barn sale a few times a year. He made a lot of extra cash selling garbage. One day while picking up a roll off container from "Moen" (...

    thread measurements 13/4X8 T.P.I.

    Lathe nut I think the confusion is in the terminology that you used. A metric thread is measured in mm per a single pitch not per inch. So your 4mm pitch gauge would mean that from the crest of one thread to the next would be 4mm. Imperial threads are measured as how many in an inch( TPI ) If...

    Mastiff lc mason engine REDO .

    Yup, mystery metal. I have come across this many times. When I figure out I have no idea what it is I usually label it "SIW" Because I all I really know is it " Sinks in Water" ( use at your own risk ) I have several pieces of "SIW" reserved for non critical tasks :) I am glad you found...

    Hi George He stated in the last couple of sentences "This completed the camshaft except for the custom helical gear needed to drive the distributor. That gear will become its own project later. Scott

    What Fillament, wall thickness and Fill Percentage for Patterns

    Now that would be COOL !! :cool: Scott

    What Fillament, wall thickness and Fill Percentage for Patterns

    Jason You are correct. The minimum suggested layer height for a .2mm nozzle is .06mm and for the .4mm nozzle it is .08mm, not a lot, but smaller. But if time is a concern the .4 nozzle will print a specified wall thickness twice as fast.( or 1/2 as many passes. Fun fact The Bambu nozzles have a...

    What Fillament, wall thickness and Fill Percentage for Patterns

    A .2mm nozzle will make corners sharper and provide finer exterior detail but will not do anything for smoothness. Layer height is what makes prints smoother. Scott

    What Fillament, wall thickness and Fill Percentage for Patterns

    Hi Jason The Bambu P1S has an enclosed chamber and can print ABS very well ( I have one too ) The big benefit to using ABS is that it can be vapor smoothed with acetone. I would suggest using a .4mm nozzle with 3 walls and 15-20% gyroid infill. And a small layer height like .1 or .16mm. This...
