Progressive Castings for iron and Skellerns for the others. (owned by the same people now anyway) 1 Quote Link to comment Share on other sites More sharing options...

Its at Fisher and Paykel PML. Not sure of the exact machines but they have some pretty amazing gear. The last photos are on a 4 axis to do the angled cam and exhaust faces + valve guides etc. They can do some seriously good work! 1 Quote Link to comment Share on other sites More sharing options...

flyingbrick Posted May 26, 2017 Share Posted May 26, 2017 I have met a bunch of those guys and went for a job interview there (failed)- a genuinely GREAT bunch of people and even the owner is such a nice bloke- I was extremely surprised to actually be interviewed by him and basically sat there the whole time thinking about how hes the smartest person I'm ever likely to meet and IM NOT WORTHY etc. SOOO good to see that they have made this milestone as they all really really deserve it. 4 Quote Link to comment Share on other sites More sharing options...
flyingbrick Posted January 23, 2019 Share Posted January 23, 2019 Great seeing your update. This is still probably the greatest project I have seen- unbelievable what you are achieving. Ps, do you have a cnc mill in your shed?! Quote Link to comment Share on other sites More sharing options...

Its a good machine, takes a bit of manual G coding but gets the job done. Here in 'Murica though I only have a printer to keep me sane! 5 1 Quote Link to comment Share on other sites More sharing options...
Bluebird_U Posted January 25, 2019 Share Posted January 25, 2019 The design and printing of the engine is great - and causing all sorts of problems in the brain with ideas vs reality and no skill what so ever, but with regard to the images showing the poring of the crank case, the vents around where the piston liners show 3 on one side but not on the other whereas the rest seems symmetrical? Are they just not shown or is the flow/ pore path through the wall and top close enough so they are not required. Would you have any recommendations for books for forms and casting for dummies? 1 Quote Link to comment Share on other sites More sharing options...
75swb Posted January 25, 2019 Share Posted January 25, 2019 This is pure engineering porn! Apologies if I've missed it, but I assume the plan is to build a replica at some point? Or just become the world leader in early bugatti engine castings? Quote Link to comment Share on other sites More sharing options...

Are they just not shown or is the flow/ pore path through the wall and top close enough so they are not required. Would you have any recommendations for books for forms and casting for dummies? Generally I put a feeder/riser where I think there might be a lot of shrinking. Either a lot more mass than whats next to it or lots of thin sections going in opposite directions (which is whats happening in this case) Youre right, in the middle would be more logical but there is a small detail there that I dont want to lose. To be honest the whole system might be terrible. Those feeders may or may not even be needed. The runner system and gates are probably the wrong size too! But I follow the guidelines and after the first pore I will learn a lot and go from there. I have very little experience in designing runner systems so its more good luck than good management. This is what I have followed from the start. Its been good, it got the cylinder block first crack! https://www.amazon.com/Castings-Practice-Ten-Rules-ebook/dp/B001OQBLZ2/ref=sr_1_1?ie=UTF8&qid=1548464690&sr=8-1&keywords=casting+practice+10+rules 1 hour ago, 75swb said: This is pure engineering porn! Apologies if I've missed it, but I assume the plan is to build a replica at some point? Or just become the world leader in early bugatti engine castings? Yeah for sure. Long term the plan is to build the car and a long the way engine building can fund it. 4 Quote Link to comment Share on other sites More sharing options...

Clogging, warping, delaminating, poor quality 10kg of material wasted and 3 weeks changing parameters but learnt a lot and got it sorted. Now I need to figure out if I can recycle this stuff! given your 'day job' it wouldn't surprise me if you had a hand in this too? https://www.space.com/made-in-space-3d-printer-recycler-launch.html either that or it's relevant to your interests! 1 Quote Link to comment Share on other sites More sharing options...

Yeah that would be handy. I looked seriously at it for a while but they just arnt reliable enough yet. Not on a large scale anyway. The risk of clogging a print goes way up which just gives you more material to recycle! PLA is good cos its made from corn starch and it composts in a couple of months in an industrial compost. 10-20years in a normal compost! But thats still better than 10000years for APS. 1 1 Quote Link to comment Share on other sites More sharing options...

flyingbrick Posted November 12, 2019 Share Posted November 12, 2019 Is it because the corners need to come out before the rest can be removed from the sand? 2 Quote Link to comment Share on other sites More sharing options...
