Keep it coming!

I bought a mig a month ago and am just learning how to do this welding thingo :) Don't ever envisage I would ever be welding titanium though. Looks fantastic!

ok here is the rotors,as you can see the side seals come longer so you can file them back to the clearance you want....this takes ages,my view this is the part that can make or break the engines reliability(not just side seals but all the clearances as there are many others)

these are the oil control rings that stops the oil that flows through the centre of the rotor entering the combustion chamber,the oil lubes the centre bearing and cools the rotor itself.The oil control ring is metal with an o ring that fits inside the outer ring and inside the inside ring

rotaries get built from the front to the back so we start with the front plate,fit the stationary gear(which has also been carefully clearanced)

aftre being bent over from both nissan and mazda i have lots of vaseline left so coat the front plate with it

then prep up the front of the first rotor by fitting all the seals and springs,the corner seals have tiny springs under them,as do the side seals and oil control rings

here is the front rotor covered is vas ready to be dropped onto the front plate

gallery_2711_155_348173.jpg

then fit the backside of the front rotor with all the same gear

and your ready for the housing,these rubber bands are a sort of head gasket.The inner one is made of some strange heat proof material as the combustion heat and gas give it a hard time

the join part of it goes near the intake

i like to use threebond in the groove

then drop the housing on and fit the dowls in

gallery_2711_155_359409.jpg

this is the apex seal and sring

gallery_2711_155_141200.jpg

and slide them down the corner of the rotor

gallery_2711_155_266356.jpg

next drop on the centre plate,insert e shaft/rotor housing and build up the next rotor then rear housing/tension bolts and the core is finished :)

ok so ive been a bit busy at work but ive had some small progress none the less....ive got hold of some original Rx/808 seats for the car(as the ones that were in it were incorrect)So i need to get them trimmed...but problem is the GT's had a symbol embossed in the headrest...Lucky for me i have a CNC machine centre so now i have to make some branding dies....getting hold of a picture of the symbol seems to be impossible....so i borrowed a japanese brochure off a mate.It had an angle shot of the front seats....so ive roughed it out in CAD and put a pen in the chuck and drawn a 2D picture....I still need to do some fine tuning/resizing and reverse the image then i will machine up the branding die

here is the proof test in plastic for the door trim stamp dies.....these are the reverse of the pattern thats embossed into the door trim....they will be milled into a 10mm plate of alloy then heated and stamped onto vinyl to reproduce the door trims.....you can see the detail in the last pic.....these were made by my 14 year old nephew :wacko:

thanks for the kind words :cheers:

heres a couple of other things i been working on....an old chunderturd....this rotten old boat has had alot of things hand formed like inner skirts,floor pans ect all with original stampings rolled into it....its been bead blasted ,all the underbody seam sealed,textured ect on a rotisserie...i have some more pics i will upload later......especially of me torching 6 litres of material just on the body shell!

gallery_2711_155_900028.jpg

and now for something better.....this is my mates rx4 coupe...ford 9 inch,series 5 turbo engine which has been bridegported and various other hot rodding.....the guy bought it over and done some work on it but has been to busy to complete it.....he had one when he was a kid that was black and loved it to peices......the poor guys been through the wars lately so me and a few of the boys got together and belted out some serious hours to get it finished and shove it in his shed without him knowing,the bonnet was completly shagged on this thing....some serious hours went into fixing it and im very happy with the way it came out :)....here i have painted it in direct gloss 2k (no clear) then rubbed it all down and a quick coat of base coat followed by one quick coat of clear with a zircon silver pearl in it....this allows the pearl to "float" and lay down flat.......what this does is gives it a large look and also it appears to be solid black until its in the sun...zircon silver pearl is purple/green/blue/red all in one and doing it this way its very clean looking(no yellowing when used on whites).....then 5 minutes tack off time then i powered on the clear....i will upload pics of the final stage when i get a chance to suck them out of my camera....these ones are just the 2k sealer/ground coat i used......

    • I have been looking at some setting on the alarms for the Q60 and what buttons do and so and also been looking for details on the alarm in my V37 which is a standard issue with the car. settings like window roll up and a few others seem to not work at all. i cant seem to find exact info on V37 alarms so Q60 is all i can really go off i have not tried 400Z alarm settings or info yet so that will be next. any one got like a sheet of info on the alarm system in the V37 as all my documents are in japanese but i thought the system would basically be like standard through similar models? 
    • I had a fuel smell coming from the drivers rear and pulled the tank out to inspect where it was coming from, turns out the breather hose from the tank to the filler neck was perished. I’m going to Japan next week and I’ll grab it while I’m there  pulled the oil tank apart and started cleaning this crap out of it, some brake cleaner and rags got it looking new again 
    • Hmm. Was quite a few years ago now. I think I bought from a crowd in the US called CDT Audio. The speaker is the HD-6. The HD-6CF would have been the better option (based on T-S parameters), but they were discontinued in 4 ohm at that point in time. The HD-6 is a better driver in almost every other way (than the CF) - just not as good in IB. They still do the HD-6. They might even have a more suitable (for IB) option here.https://www.cdtaudio.com/cdtnew22/products/components/woofers/midwoofers/midwoofers.htm But, here's the rub. I was working in the US a lot back then, so I got them delivered to my US office and then just brought them back to OZ myself. I don't know if they will ship to OZ, and it probably wouldn't be great cost-wise anyway. As to results. They're driven direct off the rear channels of my headunit, because the headunit can be setup to run the rears as subs. So, not a lot of power being fed there. Nevertheless, there's no shortage of volume - the sub levels don't need or want to be boosted at all. The bass is definitely not what you would call "tight". It is definitely a bit delayed compared to a proper sub. But, with the great front soundstage and really good 6.5" woofers in the front doors, I'm getting most of the bass detail from the front and the rear is really only to extend the bottom end a bit. Works for what I'm doing. I mean - until recently you couldn't really hold a conversation in my car due to the fuel pump, and for many years I had tyres so noisy (Kumho KU36 at <50 tread depth) that I had to drive with earplugs anyway!
    • curious to know what drivers you chose and the results? quik mafs, says two 6.5s should roughly equate somewhere between a single 8" or 10" driver. i agree that IB is definitely the way to go in most cars imo.
    • S13 and R32 rear suspension geometry is horrible once you lower it (which everyone does). The camber & toe out ramp is very aggressive, hence it's common for the S13 boys/girls to use a S14 or S15 subframe as the geometry is light years ahead. I'm sure the same can be done on R32s, but I don't know anyone that has done that.
