Hi John,
I think so, the goal is a pretty basic shape that can be altered later by riveting pieces to it. I might need to add a small bulge to hide the outside of the shoes toe box.
Much easier to make a separate aluminum part and fasten it to the fairing than to make the bulge directly in the fairing side, that would probably warp the whole sheet.
Cheers! /Anders

I´ve started on the right side fairing now, very tricky to get the progressive curves in three dimensions right. Olov has an English wheel that I will borrow later to try to smoothen out the worst bashing marks. Cheers! /Anders

Hi Anders
Tell people is got the "golf ball" finish to enhance the boundary layer , baffle them with science ;-)
Not long to go until you guys start packing up and getting ready for some fun on the ice ,.......... and I get my annual hit of "wishing I was there" .
Cheers John

I tried the english wheel when I was at Olovs place and finished the last of the stuff before Speed Weekend, I have never used one before but after some pointers from Olov I managed to get the fairing in pretty decent shape. I really wish you were here too John, I think you would have a great time around all of the rockets, gas turbines and the huge pulse jet sled. Plus, Olov has brewed a whole keg of strong apple cider! Cheers! /Anders

I will take lots of video footage for sure, I don´t know I can upload anything while at the race though (crappy internet connection and very little time to make the videos) but I´ll get it done when I get back home.
Cheers! /Anders

Remember "MYTH BUSTERS" proved the "golf ball" texture was faster and had lest wind resistance and went further... Always a thought...

Great weather at the race, a bit of trouble with the oil system as usual but we hope to get a full run out of it tomorrow!

With the jet kick racing done for the year it is about time to get the bike sorted out for the summer racing, so far I have made good progress but I really want to get it ready for a test run as soon as possible so I know that everything is ok. I made the last brackets for the side fairings and asked my feancee to take a couple of photos with me on the bike so I could see how the fairings follow the leg angle. The rules for the APS bike class says that the legs must be fully visible from the sides, plus I don´t want my legs to get caught on the fairings when lifting them from the ground to the foot pegs when starting a run. I could see that there was a bit of trimming to do, aluminum is as you can see much easier to work with than stainless. Now it looks much better, no problems moving my feet off and onto the footpegs any more. When I sat on the bike I noticed that my right knee hits the connections for the air and propane hoses, so I decided to move them and at the same time mount them much sturdier than before. On a side note I can really recommend Migatronic tig welders, they are a real pleasure to weld with compared to the machines I have used before. The fittings are in place, now they are both out of the way and fitted rock solid. Cheers! /Anders

The only real issue I´ve been having with the bike during the runs is that the engine tends to flame out when I start braking, the oil is thrown forward, the oil pump pickup sucks air and the oil pressure switch cuts the fuel pump. With a full oil tank and easy braking it can be avoided but it is definitively something I need to fix. Point of no return... Now both tanks have a nice big hole in them, the fuel tank has one internal baffle but the oil tank was completely empty. I must have forgotten to add baffles to it before I welded the lid on, no wonder I have had problems with it... I made a pair of stainless lids and borrowed a nut riveting tool (don´t know the english word for it...) from my friend Olov. I really need to get me one of those, a very useful tool! I removed the fuel tank baffle and spent the next half hour cleaning out the fuel tank, when I was satisfied I cut out a block of tank foam for it. I will fill the oil tank with foam as well, a bit unusual perhaps but I cannot see why it wouldn´t work with 0W30 oil just as well as with kerosene. I guess I will soon find out, with the newly added lid on top of the tank I can easily remove it if it for some reason won´t work. Cheers! /Anders
