    Printer problem

    While back on my now defunct CR10S PRO V2 I had a y axis lost steps problem. I was already printing with a heavier bed due to using a 6mm ally toolplate with mains bed heater and magnet, but it handled that weight ok until a year later. It only skipped when I was printing at high bed...

    My Jerry Howell v-twin (s/n #599) has sprung into life

    As addictive as 3d modeling is and 3d printing is, I suffer day and night 🤣😂

    My Jerry Howell v-twin (s/n #599) has sprung into life

    What a beauty really. This engine is on my list for me to convert to a 3d printable working model. I already did the same with Howel's Vfour, https://www.printables.com/model/714791-working-model-of-the-howell-v-four-engine. There is info about that model in other threads here too. Wanted to...

    Jerry Howell's V-four in 3d printed form

    Oops, even when reading your messages and trying to find the missing files, I forgot this one again yesterday. Anyway its uploaded now as V2. I also read the instructions again to see if your questions are in the list and they are. Except for the radiator flat on its face, which I took as...

    Jerry Howell's V-four in 3d printed form

    This is on tab nr 4 in the instructions. Upright on the fan side of the engine. If you use supports as I instructed they are much easier to remove then you expect. Needle nose pliers and a sharp knife is what I use. Whole sections of this support comes of in one piece due to the heavy transition...

    Jerry Howell's V-four in 3d printed form

    Hiya again. The missing files have been added, many thanks to point this out to me. Also the duplicate exhaust manifolds have been rectified, one version was in fact old and needed to have been removed. With regards to the spur gears, yes the teeth pattern and count is the same but the shaft...

    Jerry Howell's V-four in 3d printed form

    Hi Gunna, I will have a look of course but could you do me a favour please and repost your questions on the printables website so my answers there may help other builders also? I posted it here to make people aware and for me to answer peoples questions on different sites will not help all of...

    Jerry Howell's V-four in 3d printed form

    Absolutely correct, and add to that the possibility of drawings being "instructional step by step sketches" which have the measurements for that step on the drawing instead of final part size, the mayhem is near complete for those who deal with reverse engineering in order to produce 3d models...

    First and Third Projection Symbols

    As always the industry has to declare a standard. Since they declared differently in different parts of the world we have different standards. It is simply to make everybody do it the same way and always the same way. It does not mean there are better or easier ways, or that your way is wrong...

    First and Third Projection Symbols

    When I was learning to draw, with pencil on paper, our teacher told us an easy little visual way to tell them apart. First angle is when the object ( in this symbol) appears to be flipped on its side as if you pushed it over onto that side. Third angle is when the object appears to be swung into...

    Jerry Howell's V-four in 3d printed form

    To put every bodies mind at rest, once and for all I hope, I never criticized Jerrie's plans at all. I simply stated that I was using them for producing 3d models from them, which was very difficult since the plans Jerry made were instructional drawings for machining, not final part drawings...

    Question about lost PLA casting

    I think he meant My, but in technical terms in metric, it could be short for micron, from the greek letter Mu (not on my keyboard so I cannot show it here 😁).

    Jerry Howell's V-four in 3d printed form

    So I have started this monster project whereby I purchased the PDF drawings for Jerry Howell's V-twin and his V-four, with the plan to convert those drawings into 3d models good for printing on a normal FDM printer we all have at home, right? Well as it turns out the drawings are not ready part...

    Question about lost PLA casting

    It is horses for courses. Resin is hard to beat on minute details and smooth surfaces. But the process is nasty, dirty and smells. Besides the waste materials you need to comply with local laws for disposal, I think even if you were allowed, to simply flush it down the loo is criminal. I would...

    Unsatisfied !?

    For me it is a question of balance, which has, albeit in other words, already been mentioned above. I have looked at my V8 flatty many times for many months before I decided to reprint the whole engine case. This took over 50 hours of printing, so it was not an easy step to make. Plus after that...

    Tiny holes and even tinier grub screw!

    It wasn't my day and I should have stayed in bed. I was finishing of my Ford V8 flatty model engine, all 3d printed but for the bearings and the fasteners. Installed one bank of 8 valves and about to do the second bank. I had already closed of the sump, which in hindsight was a mistake of...

    Sudden Problems With my Printer

    I know this is an old post, but doesn't hurt to offer help if one needs it. I have a foolproof way of leveling my bed on a 300 x 300 mm machine. After that I make my own single layer print to test it. I learned this way of doing it after many frustrating attempts trying to follow advise from...

    Draw-Tech

    Quick update of what was modeled today.... Jerry Howell made drawings that are step by step machining details. It is very very very difficult to derive at the finished part measurements while not actually doing the machining. But slowly. I would truly love to have a go at the Knuckle head in...

    Newbie from Bulgaria.

    Hello fellow petrol-heads, engine nuts and last but not least, engineers. I am Kees, 3dcase, Dutch but now living in Bulgaria. Been a machine engineer all my life and now applying my experience to new technologies and newly learned skills. Can't sit still and I don't like TV, so I 3d model in...

    Question about lost PLA casting

    Hello guys, I don't cast, so no knowledge to share on that. But I do 3d print, a lot! My printer hardly stops. So from the surface of the model point of view I would always expect to have to rework some features. I know with casting you do have to face and bore or drill holes afterwards, so...
