    Apprentice Demon V8 Build

    Just a quick update. This is where the oil pan is atm Mark: I really appreciate your comment, that's very high praise indeed! Im more or less self taught and have been trying to do this with as little input from my mentor as possible. Steve: Thanks very much. Every time I looked at the...

    My overengineered 3d printer

    Thanks I appreciate that. The carriage doesn't need to be driven by the toothed side as its a sympathetic pulley arrangement. All that the motor is doing is shortening one loop while making the other side longer. its kind of hard to explain but to answer your question, there is no drift as its...

    Apprentice Engineer

    I dont mean to be a buzz kill but the #25 should be far too easy for you. Im a 1st year apprentice myself and ive just started building steves demon v8 engine with the hope of a decent challenge. Im not necessarily suggesting that you take on a v8 but at least consider a Poppin vacuum engine or...

    My overengineered 3d printer

    Its working!!! All i had to do was shorten the thermal barrier so that almost all of the cold side was in contact with the heat sink. It still needs alot of fine tuning but im happy it will now make it through a print quite reliably. The biggest issue that ive found now is that Slic3r produces...

    yea i purge the extruder every time i attempt a print. I just tried printing with abs and am still having the same issue:mad:

    My overengineered 3d printer

    Thats what id initially thought but it doesn't seem to be the case. the pictured failed print was done at 180 degrees but ive tried temperatures up to 220 with the same result, i could try higher but from what ive heard 220 is rather exesive

    My overengineered 3d printer

    Im using two 5.8ohm(or thereabouts) wire wound enamel resistors in paralell. they are powered from 12v and controlled via a cheap PID controller

    My overengineered 3d printer

    You has cookie :P its steves demon v8 ive started work on the block and thought it would be nice to have a 3d model of what i was making the first print i did on it was steves block as pictured below, the resolution is terrible as it wasnt really calibrated at that point but it did work, I...

    Demon V8 Slow Build

    Ive just started the block, im not at that stage yet but ive been trying to work out how to cut the water jackets. the only way i can think of at the moment with out cnc is to center each cylinder bore on a rotary table and spin the hole block around, is this how you did it?

    Challenging parts for training

    Your quite right Tin sorry about that. What i was trying to say is that it would be good to see some of the parts that people have come across at work that are particularly difficult. is that any clearer? i know its a bit of a stretch as most people wouldnt take pictures of that kind of thing...

    Challenging parts for training

    I would love to make stuff of that complexity, i have the plans for steves v8 that i want to build but i dont think theyd let me do that at work :P

    Challenging parts for training

    Hey guys Im about 6 months into a fitting and machining apprenticeship and to put it simply im not learning anything as far as the machining goes (im 19 btw). The parts that we make are so basic im not sure id call it machining. What scares me is that not long ago i made what i was told is...
