Can you please address the EPA trying to kill our car culture and community and some of our lives if you do not know the EPA is trying to ban everything car related including tuning, boost and many other things. We are under attack we need to address this now before it becomes too late. We can counter this if we gain Support for the RPM act the link to SEMA's page on it is listed below. Please give support so we can keep the car culture alive. To give your voice and save this thing we love go to www.sema.org/epa-news

This is genius level machining and engineering. I've known master level machinists that would be proud of your work. Look out for the differential expansion of aluminum and the steel rods. It may be an issue with the aluminum housing and the steel rods may cause distortion of the combustion area. Try putting the housing in the freezer before final assembly. I'm not a great machinist. I'm just thinking about how hard you beat these engines and I think some distortion is going to happen at high engine temperatures. The apex seals are very delicate compared to piston rings. Just consider it. I don't know the specific metals or if they are cast or forged. I have faith. go for 2k hp.

Do some more reading on your Renishaw probe macros. You are able to probe those two opposite dowel holes and calculate the angle to tell the machine to apply that to the WCS. So you post the real coordinates in your GCode and the machine applys the rotation offset. Good work so far 👍

All rotary motor lovers should be knowledgeable about hydrogen fueling= high compression, higher octane = more horsepower, more miles per gallon, far more efficient
Mark Robinson
Mark Robinson پیش ماه
You should add direct hydrogen fuel injection, using dry hydrogen fuel cells for increased horsepower, longer engine life, cleans out the engine, adds higher mileage per gallon extending your driving range, also hydrogen gas is higher octane than gasoline and e85 meaning you can run higher compression ratios = more practical and itll sound like an f1 car

If you're testing this thing on a dyno then instead of pushing single gears to it's max rpm one at a time. You really should be shifting at ideal/optimal times and using the dyno data to do real time calibration right then. To your car's computer. Your shifting in the Ken Block race was sub.

I would use single set for the first cut after you programmed something. So that way the machine only reads one sentence and after you start again, the next sentence. I would also slow down the feed and the rapide traverse. You can avoid colisions in that way. When programm is fine on the 1. Set you can changr to fully automatik. Sorry for bad translation

Rob, pilot holes and reams are your friend! Also End mills usually don't facilitate cutting straight down, end mills are great for pockets but drilling is best left to drill bits and remember, go up in stages once you've drilled a fairly decent pilot hole then you can finish it off with a drill bit going a little slower then ream it out to it's final point Edit, in some cases you can run reams fast but personally when i made tooling i'd take the reaming stage slow because that is truly a make or break moment.

you should put a champfer on the holes before you reem them. It increases the lifespan of you tool. Als the dowelpins dont get damaged in the assembly

I understand Rob likes to learn stuff himself. And in no way am I taking away what he has accomplished so far (it's fantastic), but in this case I feel like he would benefit so much from asking a professional for tips just so he can get those precise holes. We're talking .000 mm here which adds up quickly when doing multiple holes on multiple rotors.

Opening up a deep hole is a job for a boring bar. Fyi. End mills chatter, and are not for drilling. Reamers deflect whether you like it or not. Get a kaiser microbore head. READ A BOOK, TAKE A CLASS.

Two things rob, one ditch the endmill and get a drill., two, you WANT the reamer to be slow, at that size on a g85 you would be looking probably pretty good at s700 f7. As long as your coolant is the right % range

You may want to consider performing a couple of tolerances stacks for the motor housings if you're planning on doing full swaps universally. While you can hold precision you're going to end up with a distribution of the tolerances from one end of the bolt hole true position spectrum to the other. it's actually a fairly simple stack as well since you're dealing with just a dowel connection and bolts in a pattern but will save you a nightmare later on when you go to match two edge case (but still within spec) housings and they don't go together because they're on the small end but also shifted either circumferentialy or radially relative to one another.

Rob, dude, put your safety glasses on before using the air to blow away chips. Trust me, you DO NOT want a metal chip scratching your cornea. It is no fun at all. Also order a bunch of 123 blocks. You've spent so much money and time trying to ream a perfect hole but if you're using random scrap chunks of aluminum in your setup you're going to ream those holes at a random angle. More blocks + more clamps = more accurate hole.

Fixturing will help with everything tackling a project like this. You could make a fixture based off those 2 outside dowels so that you can put the parts in at the same location every time. It would likely be a bit outside your comfort zone but getting a solid fixture down will help tremendously.

You can get a ball hone to help deburr and smooth out the bore after the reamer. It'll help make everything go together that much smoother, and more importantly, come apart easier. Like others said you should either cut a chamfer on the leading edge of the bore with the HAAS or do it as a manual op with a die grinder.

I started learning CNC at home myself around the same time you got your HAAS. cept mine is a crappy g0704 conversion in my garage... glad to see we are at the same point in our lives trying to figure this stuff out. Your metrology gear is really amazing and I covet the tool changing/tool holding stuff which definitely takes some of the terrifying guess work out of doing this stuff... (I literally touch off the part from each side to figure out where I am at and i use a 5v signal on my tool and part as an E-Stop to get as close as possible. Any rate, keep up the good work and learning this stuff. you're going to make some amazing parts once you get the hang of it.

You should invest in some real drill bits, the end mill you are using is not ideal for going straight down, they are more used in going down with a circular motion but as of right now you should start pecking with what you've got

ROB, take that two rotor test assm. & flip it bolts-down on a table & drill holes. Now insert 5/8 PVC tubes (the lengths of the bolts) into the table. That way as you tap them out of rotor assm. for teardown, the bolts come out straight by the capture of the pvc. Will help keep holes In rotor true. Pop some caps on bottom of PVC tube (so bolts don't just drop through to the floor) for 1 man operation. Will look like a PVC tube jail but under the table. May also need to brace the tube jail as pvc can flex a good amount. But then you could build one out of moly tubing for more stability now that u can weld 👍

When will you start working on the new corvette. I love the work and builds you do because other then b is for builds all other car IRpost channels do the same thing turbos, superchargers,wraps, and wide body kit anybody can buy. I love real custom builds that you have make the parts or use part from different cars. Like me I have a custom 1967 fastback right hand drive mustang that was a 1968 coup left hand drive mustang it took 4 years to do it because parts were not made but the firewall and metal dash but I could not get the dash it was on hold for 3years they said so I had to normal dash cut they in to 3 part and moved they to the other side so it looks the same as the ones you can buy now but I did not put a stupid ashtray. I like good custom and weird builds. I just have not decided to fuel injection or do a 2JZ swap because I just move to Colorado Springs and carburetor suck here. Keep doing the same work don’t change because people say it stupid or waste of money and time.
