Col Posted November 6, 2016 Share Posted November 6, 2016 The stubborn wheel that listened 3/4 id x 6" drivers, home cooked pine bp, various microstars, metals and a bounce. 2 Link to comment Share on other sites More sharing options...
OldMarine Posted November 6, 2016 Share Posted November 6, 2016 Did you use separate drivers or were those just really stubborn delays? Link to comment Share on other sites More sharing options...
Col Posted November 6, 2016 Author Share Posted November 6, 2016 Hi OMSeperate drivers on a hexagonal reloadable wheel frame. The drivers were linked with two strands of BM in swept/curved matchpipes which is usually very reliable. The transitions on this one were stubborn but very consistant at almost exactly 5 seconds each. Link to comment Share on other sites More sharing options...
OldMarine Posted November 7, 2016 Share Posted November 7, 2016 If you'd mounted that twice as high I think the microstars would have shown more impressively. Still very awesome! Link to comment Share on other sites More sharing options...
Col Posted November 7, 2016 Author Share Posted November 7, 2016 It was mounted a shade over 6ft, i`d have needed the ladder for12ft Link to comment Share on other sites More sharing options...
Mortartube Posted November 7, 2016 Share Posted November 7, 2016 That's excellent! What was the basic driver comp? It was lovely and fierce. No sluggish bits there. Nice micro stars too. Link to comment Share on other sites More sharing options...
Col Posted November 8, 2016 Author Share Posted November 8, 2016 Thanks matey,The fuel was just basic 75/15/10 with homebrew pine charcoal. The trick is to use a short core (1 tube id long) to spin up the wheel instantly. Using a loading funnel with the same id as the choke ensures the microstars can exit easily.

Mortartube Posted November 8, 2016 Share Posted November 8, 2016 I have made small wheels before but they weren't as good as that and I have never done them with microstars. Nice tip about the funnel too. I am inspired for next year. Link to comment Share on other sites More sharing options...
Col Posted November 8, 2016 Author Share Posted November 8, 2016 Its worth knocking up a reloadable frame or two. All you need is a skate wheel (1/4" bore bearings) and a bit of 3mm ply or 4mm mdf and 3 stainless self tappers. I prefer hexagonal frames which allow for 2, 3 or 6 drivers. The drivers attach with 4 nylon cable ties (3/16" wide) which locate into slots filed into the edge of the frame. Once the ties are tightened the drivers are locked solid. I always add a line of hotglue onto the tubes either side of the ties to provide added security against slippage. Link to comment Share on other sites More sharing options...
Mumbles Posted November 8, 2016 Share Posted November 8, 2016 Have you ever checked the drivers and zip ties after firing? I've always wanted to use them but have been concerned over them softening or melting. I guess it's clearly not an issue. Link to comment Share on other sites More sharing options...
Col Posted November 8, 2016 Author Share Posted November 8, 2016 (edited) Hi MumAs long as the ties are good quality nylon ones and the drivers dont explode they`ll stay attached. Luckily, I threw the wheel in the shed to protect it from the rain and didnt get around to cutting the drivers off yet so i grabbed a pic. I tried something slightly different with this wheel, i cut arched sections from a (black) tube and glued them onto the drivers for anti slippage duty.
