Hey Sal, Thanks for all the advice. I've decided to go with the dimensions given from the JetSpecs program for my first time, and see if I need to adjust...
Hi Mark Andrew has a video of FMs last unsuccessful test run , including the sounds of the compressor grinding away inside its housing after the bearing...
Hi DP It all boils down to how much thermodynamic energy you have downsteam of the gas producer turbine (jet pipe energy). This will influence the potential...
... It's worth noting that RCDon has already had a failure with his simple freepower turbine--I believe that one or more blades departed the hub. Given the...
Matt the turbine inlet has a nice round opening designed for a band clamp. I mates very close to the outlet of my CC I need to weld a 1/8 inch round stock on...
It has been a while since i went through the ROT section. I forgot that was in there. I will take a look through there. I actually will be using sanitary tube...
Hi Anna, Yes, get a tube that fits over both holes, the hot gases need to enter both. You can't do much, if anything at all with a divided inlet you'll just...
Hi I hope I'm misunderstanding something here , but the inlet to the turbine stage is generally the rectangular opening and the exit the round one with the...
Hi John, yes sir the inlet to the turbine is round for a band hook up. I uploaded a pic of it in the photos section Billy's Project. It will make for a easy...
Do you have any videos of of it on the kart. Is this your work?? http://www.youtube.com/watch?v=9AyOFxYd7Ms&feature=user It is one of my favourite turbo jet...
Bill, Thanks for the input. I was actually planing on using stainless. I will be using 316 sanitary tube for the blade, and 304 schd 40 for the hub. I have ...
My computer crashed in the recent past, but I am just noticing it took my JetSpecs Program. I looked for a replacement today in the Files Section, but couldn't...
Hi DP May I suggest you grind the blades , turning can be problematic , I found out the hard way :-(( Schedule 80 is probably overkill, Schd 40 stainless will...
Hi I have just uploaded a video of my jet bike to youtube search under joolzned. its not running yet I am testing the electrics. I hope you like it....
They have some sort of mill/ lathe setup at work, basically it is like a lathe will a spining bit (end mill). that does the cutting. The guy (he was older than...
... I have some ideas about that.............. The circular section that you use needs to duplicate the airfoil section it would replace--at least to some...
Hi DP Before you go too far with your bearing choice I'd suggest finding out exactly the rpm figure you'll be working towards , and for that you'll be needing...
Im working on a side car for one of my chopper projects, and came accrossed this fun pic...its only a cooler for drinks, but it might be fun to make if your a...

I'm sorry that this question has nothing to do with turbines but after reading all these posts on bearings and bushings, I'm sure that somebody on this forum...
Good evening If you are referring to granulated or porous bronze bushings it is not too difficult to infuse a liquid lubricant. If the bushing is of fairly...
When you say "honed", hopefully you don't mean "enlarged with some kind of abrasive". This type of bushing needs to be reamed to the proper size, if it's too...
as part of a turn key package. is it possible to spin the free shaft (power) to start the engine? I am looking at ways to start the engine without the use of a...
Hi DP No point spinning the freepower , it can't start the gas producer . Some sort of high pressure air inpingement is probably the next best thing to the...
