All this in a weekend

Pulled the engine/trans from the project FD RX-7

Finished the front mower deck bracket and most of the pulley/tensioner on the monster mower

Started wiring a fellow rotorhead's very clean car with a Haltech Sprint RE and lots of other fun goodies.

Finally cleaned up some calibrations on the 3D printer and now she is printing much sweeter...  Though right afterwards I did tear it apart to put the heated bed on it.  :)

What? Another RX-7 I must be crazy

Picked up a 94 FD RX-7.  Blown engine, rust, bad bodywork and bad interior.    Next decision what powerplant 20b NA or 13b 5866.  

It Works

Well I am now printing.   Did the majority of my calibration and setting of parameters for PLA with my E3D V5 hotend.   It appears the fan on the E3D is a bit small and was causing the PLA to jam after printing for 30 minutes or so.  I played with the temperature but will make a new shroud for a larger fan and try and cool the transition from the block to the fins.  I have a heated bed on its way and need to order some ABS and Laywood to try.

Delta Printer Mocked Up

Well here it is in all its glory.   This is the first mock up of my 3D delta printer.   Its using 1020 aluminum extrusion so I had to modify the mini kossel parts to be able to use them to make my life easier.   Hoping to have more rigidity in this setup.  Waiting on an Azteeg X5 with 32 bit ARM chip and 32nd microstepping.   Using an E3D hot end and thanks to Jon on the delta printer google forums I will have a better fan integrated effector.

CNC Spindle

Here is the start of the ER Spindle setup.  I have a treadmill motor that I will attach to the spindle section.

I don't plan on using the HF router setup but I could...

Here's the tread mill motor and yes I took it apart.  I'm working on DC motor designs at work so lets just consider this benchmarking.

Starting on my "Kossel" 3d printer frame...

Getting excited when you receive items like this in the mail.

CNC Working On It

Here's where I stand on the CNC.   Trying to get all the misc issues cleaned up.  X,Y,Y Slave are working.  Running a G540 Gecko control.

Working on an ER20 collet spindle with a gear reduced trim router motor.  Should give me some tooling flexibility and by using heavy spindle bearings should prevent router bearing problems.

RX7 was sold.....

Well this summer I sold the RX7 to Derek King in the Fort.

Rebuilt a 2011 WRX Hatch as a daily.  Definetly better than the Scion TC which was also sold.

Next project..not sure yet

Spring Startup

FueLab Fuel Pump Assy

Gone with the dual Walbros in with the FueLab pump brushless motor and controller.

Muncie

Decide to push it a bit with low mileage on the engine and am now pushing almost 15 psi. Took the 7 to the track ran a 12.6 @ 115.6. Not bad but I'm a terrible launcher. So I'm sure I should be in the 11's. Toasted the clutch on the second run with the 12.6 so I will be putting the 6 puck clutch disc in.

Running

Well I have neglected the blog but I rebuilt with a new rotor as well as font plate. Engine now has 300 miles on it.

Water Injection Is BAD???

Well broke my front iron on a lower boost run. Had some miss-fire and then oil pressure dropped to nill. Front plate broke at the oil turbo feed and across the dowel. On tear down it appears that I was pushing too much water, as the front rotor also pinched an apex seal but didn't break it. Again all this is my opinion of what happened as the settings, fuel, and pressure I was running should not have created detonation. Oh well time for a build. I will start over with smaller nozzles this time....

Water Injection Is Good

Boost appears to be approximately 2-3 psi higher with the pre turbo and pre TB water injection. AFR's were 1 afr lower than before. Scared myself when boost cut went off after hitting 18 psi on wastegate alone. No full runs in 3rd yet but 2nd is all spin.... its good.

Seats Are In

Seats are in and they fit wonderfully. Also put in a new black carpet to clean up the grey carpet from before. These are the seats that should have come in the 7 standard.

She starts correctly again

whoooho! Haltech put out a fix to their firmware uploaded it and now she starts on first crank. Ign1a coils are working great

Seats: Wife and Dessie Approved

Wife and Dessie came home and guess what the seats are approved by both of them.

Hmmm New Seats....

Well look what showed up today. Might the be a pair of mint condition Lotus Elise seats with lumbar adjustment??? Yes they would be. Stock rails will be here monday for me to modify for these babies to go in.

BAM BAM

Wired the fuel pressure sensor, oil temperature sensor, ECU ground and Alternator tap. Then in order to test I turned on the launch control. Not necessary but made Dan laugh. Oh and don't you love flames and extreme backfires...
