RichK 8 Posted December 20, 2020 Share Posted December 20, 2020 This looks amazing. What brand/model of filament did you use in the end? Quote Link to post Share on other sites

I ended up with formfutura apollox asa. I had tried umpteen different temperature combinations, brims, part cooling, adhesive, print speeds and layers etc and couldn't get consistency and flat prints at all with the Extrudr filament. Whacked in the formfutura and with no brims its just producing consistent flat prints. Currently using 90 degree bed and 245 nozzle. Its not cheap but it's good stuff. https://www.amazon.co.uk/Formfutura-1-75mm-ApolloX-Printer-Filament/dp/B01HIGMBBY 2 Quote Link to post Share on other sites

CosKev 1,029 Posted December 21, 2020 Share Posted December 21, 2020 Thinking I best buy a couple of pairs of these ITBs before you start selling the fitting kit?👌👍 1 2 Quote Link to post Share on other sites

Def going to be interesting. If I have both spindles operating the same way I think I can link them reasonably well. Theres a few options. A turn buckle style hard link, a split twin ended throttle cable or a jenvey throttle quadrant set up. Jenvey kit as always looks good but isn't cheap and would easily be the biggest single expense of the project if I went that way. I need to get all the pieces printed to get the bodies fitted to see what's what. 2 Quote Link to post Share on other sites
Steve (sdh2903) 3,425 Posted December 21, 2020 Author Share Posted December 21, 2020 During an idle couple of hours I was doing some more digging on why the rocketeer never fared very well on jenveys. Firstly they were constrained by the mx5 bonnet which is even lower than a westy bonnet. But looking at the cutaway of their adapters they had an incredibly short runner length. And an even sharper transition from round to oval And that bolts straight to the block wheras my setup bolts to the lower jag manifold. They look like Sfs bodies which are only 30mm long so I'd estimate a total runner length to the head of less than 100mm. And to top it off they had to use restrictive socks aswell. So no wonder it struggled to make any gains. I believe it made around 240ish vs 270 on their plenums. I reckon I will have more than double that runner length, which is still fairly short, (and not as long as the Aj30 jenvey kit at around 270mm) but won't be using restrictive socks either. So there maybe hope it's worthwhile effort. 2 Quote Link to post Share on other sites

Shouldn't really have put posts up IMO saying the Jenveys did not perform well when it was really their adapters,lack of trumpets and sock filters that were the issue😏 Quote Link to post Share on other sites

Amazed they even managed to package it all in so low really. 1 Quote Link to post Share on other sites
Rory's Dad 737 Posted December 21, 2020 Share Posted December 21, 2020 Don't know much of the technicalities but they now use two purpose built throttle bodies and different filters. 1 Quote Link to post Share on other sites
