Ahh, I recognise that word from my AutoCAD program. Thanks!

The idea was to spend all spare time on the rocket engine to have it ready for a new test as soon as I come back from the christmas holiday, but I felt like giving the turbine bike some love yesterday. I drilled and tapped 6 M6 holes where the exhaust ducting will be mounted, I have to do this now before I coat the housing with cheramics. After that I was going to bead blast the housing but ran into problems with my bead blaster cabinet that stands in the cold part of the workshop, in -10°C the compressed air froze the lines so in a couple of seconds I lost all air supply to the cabinet... ;D Something that I could do was to fit the inter turbine housing, I spent an hour facing off the sides to get an even gap everywhere. Welding thin stainless is tricky enough without uneven gaps. With everything set and spot welded in place I started welding, short welds opposing each other to try to avoid warping at all costs. I have spent way too much time on this piece to screw it up now... The aluminum tape is a poor mans root gas, works fine and cost nothing at all. With the welds wire brushed the part turned out this nicely, no warping and decent welds despite a tired welder so I am satisfied with the result. Here you can see the total lenght of the engine inside the frame, plenty of space left for a decent sized air intake infront of the compressor. Cheers! /Anders

I can't wait to see the exhaust duct, looks challenging!

John, sure thing! Just make sure you send the large compressor wheel as well so I can *ehum* take some important welding measurements on it. The exhaust duct will be somewhat of a challenge to build, but it will have to wait until I know exactly where my legs will be so they won´t end up in the exhaust jet... Merry christmas to you all!

Hi Anders, Merry Christmas to you as well. Looking forward to seeing your work on the bike and rocket engine projects next year. BTW i had a reply back from the guy who sold me the rocket engine, those two ports are for injecting another type of mono-propellent such as CNG like the Blue Flame LSR car did. Cheers, Mark.

Hi Mark, Aha, never heard about such secondary injection. I will check up the Blue Flame landspeed car, sounds interesting! Cheers! /Anders (I made the santa pic for a swedish bike forum by the way, it says "Merry Christmas, you dicks"

on that note merry Christmas to all the dicks here! Thanks for putting up w me. I'm getting ready to redo the exhaust duct on my little bike. I'm just waiting to see what you do so i can copy it. I'm prolly using 304 shim stock and the spot welder i made last year. The exhaust on the bike now gave me scars, it rubs the ground on the turns, it's too short to get a good AB effect working, burns my heels..... The little bitch threw me on my ass a few weeks ago I'm finishing it and selling it.

Heh, nice heel-burner you've built there Chris! What about your earlier bragging about coming to Speed Weekend? You cannot possibly sell the bike before you have tore up some swedish ice with it. Cheers you bastards! (A rum and coke coming right up!) /Anders

I still wanna do that. Work has been a little crazy. I think I could get the bike in a few carry-on bags
Cheers my friends!

With the holidays out of the way I could get some work done on the JU-01 again, last night I made a lock washer for the power turbine wheel. A chunk of SS2348 was cut from bar stock. Metal music on the radio, metal clippings in my hair. A perfect evening! The red liquid isn´t blood this time but a special marking fluid that helps a lot when scribing on stainless. When the part was finished in the lathe I fitted it to the indexing table to mill the curvic coupling slots. This is how the lock washer turned out. As you can see there is a hole drilled through both washer and bolt head, I will use lock wire to secure the bolt to the washer and make it practically impossible for the bolt or turbine wheel to move once torqued in place. The lock washer in place, remember that there is a curvic coupling on the other side of the turbine wheel as well so the wheel is sandwiched between the two and cannot ever rotate on the shaft. I´ll finish this with a closeup to make a long and relatively uneventful post even longer. Cheers! /Anders
