  1. Made my first payment on one of these the other day and after paying the first quarter, of 500 bucks, I took home about 60 kilos of calcium carbide. Even a grain or two held between the fingers you can smell that slightly sickly sweet odour. I got it from the man in Panmure who always looks at me slightly askance when I turn up once every few months and some rare titbit has just arrived and I'm almost first through the door. I've heard about these things but never seen one and whilst I didn't know what it was I suppose a dirty great oxygen bottle sitting right next to it made it fairly obvious . This is a photo off the net as I've a phone now but haven't had one for so long I've forgotten about taking photos whilst out and about.
  2. Excuse me but wouldn't the rotary turned end for end allow for the output shaft to then be reversed? And again, excuse what might be ignorance on my part but isn't the gearbox just a reduction drive? I got a 90cc twin 2 stroke Wolf motor off Japnut ages ago which he preceded to pull apart to ascertain that it was quite good and merely had one little end seized but in my haste to pick it up I forgot to grab the other half of the crankcase... Anyway you can have it if you want as it might make a slightly easier pigeon holing and subsequent modifications to work. Tracking Japnut down isn't a simple task but he will be found eventually and he is certainly willing, despite being very busy, to get the case to it's rightful home. I'm not saying that the rotary isn't a very interesting choice for the moped so much as waiting for exactly the right bits to find you to make it easy and less cutty cutty could be acheived by putting a simpler drivetrain into it in the meantime. And I absolutely love the rusted cutaway that shows the motor. Who needs air intakes when nature has done such a lovely job of sculpting the metal where it's needed?
  3. I've a suzuki carry van body I'm getting around to doing this to except I'm going to cut out the middle doors area and then weld it back together... oops, after cutting it into two bits I'll take out lots of the floors as well so I can build a sturdier tubing frame to mount the mini tandem wheel axles... as in the rear axles off a couple little front wheel drive cars. Final job would be taking out most of the glass and sheeting it all over. Great to see such economical use of old steel.
  4. And oops, turned out, this salt lake drop tank speedster, had a SOHC conversion added so whether such is still a flattie as cam and upside down valves removed... still quite beguiling. https://www.youtube.com/watch?v=u7nrD7yb0go
  5. http://dragonfly75.com/moto/AX100mods.html This is the guy I been reading the most and theres a link on the page to another just about the design of chambers... It's almost as if it's more about the exercise in fabrication than actually having something that works which is kinda stupid but then again I'm often a bit stupid. Like because it's just a challenge and getting my head around making cones and making them bend and being able to even weld it all together can just be an exercise in fabrication and after the bikes built and actually goes with some consistency and hopefully goes well I can get tuned pipes designed and make them in a more normal down the side and underneath kinda way... then hang the mad chamber on the wall somewhere or make it into a lampshade or something equally useless but interesting looking. The thing is also that if I could make a weirdly inappropriate chamber and the man at CC liked the skills involved I could even get some work there for pocket money and God knows some actual money would be quite nice at the moment.
  6. Yup, those flatties are well worth keeping afloat almost especially with such a twist out towards rat rods in the states and the proliferation of the V-8 variety... quite a while ago I saw a video of a chap running a 100e on a dyno and it was brilliant and even had me going to question our local Morris minor specialist, who has a place two doors down from my brothers workshop, but he's actually a complete asshole and though he said he did have a few flatheads out back which an emphasis on hidden when he started goin' on about some arcane knowledge to do with how to rebuild them... it's actually it's a pity he's such a dickhead! Recently though I found a vid of a drop tank salt lake racer and they kept to pre 40's stuff and had an inline four flathead with triple strombergs feeding a side mounted blower and had reached 165mph... epic! Bugger, went looking for it but couldn't find it anywhere.
  7. Quick and mouse driven drawing of how I want the chamber to be and as a fabrication in steel quite an appealing challenge. First I gotta gets some bends to do the header pipe and then it'll be days of cardboard measuring and calculating to make cones and then tape them all together...
  8. So I got in a day's work sorting out the front end a bit and then lookin' at it closer than I have the frame is both bent and twisted so it's taken a fairly major hit at some stage and that initially kinda perturbed me but eventually I figured I could wedge it under my car, just the frame, and most probably bend it back where it's be better suited to going in a straight line. I cut up the handlebars and tack welded then into a more suitable guise and then mounted quite the nicely shaped speedo I had lying about which is somewhat art deco in shape and I do like art deco. Then I made some headlight clamps. Next step I think will be doing a front mudguard as well as a seat base as I've got access to an english wheel and what might be a silly idea that half of some aluminium tube rolled through the wheels will become mudguard shaped... the seat though will need multiple bagging against a sandbag before it goes to the wheel for smoothing, Over the past few days, as well, I've been researching that totally esoteric and arcane art of expansion chambers and also been down to chat to the man at custom chambers to the extent that I basically understand he uses a computer program to work out the dimensions for specific requirements given the setup of things such as ports, carburettors and powerband placement... which admittedly I can't really be bothered with but, at the same time should be? I understand that form should follow function but I am somewhat too a fan of the idea that form can define function and the idea is that a really natty and suitable expansion chamber would have a header pipe that curls up and over the barrel and then the chamber does it stuff as it curls over the motor cases then snakes along the side next to, but not too close to, where the battery is with the, now I know the nomenclature, stinger over the rear shock and between what would be my lower left calf. And I know too that that is like shouting at failure of function to come and be my best friend but at the same time I might be lucky and it does actually do what I require of a motor with power. I have found a fellow who has published dimensions for a chamber for an AX100 with a really good description of what he understands as the hows and why's which is really quite detailed so if I can combine this with getting the chap at Custom chambers to run some approximations of what I have through his program I can kind of put the two together and see how close or far apart they might be. He, at CC, has also said he can just do the rolling up of cones at a labour only cost even whilst I wouldn't actually mind having a go at that....
  9. I dropped into the Custom chambers shop and he was a bit grumbly but settled fairly quickly into a helpful man. $200.00 each for the chambers and a $100.00 each for some, for what he recommends as quite good, chinese mufflers to stick on the ends. Depends now on either me, or someone else in the Auck, being able to procur a GT185 and be able to have something for the man to work from. You interested? http://www.customchambers.co.nz/
  10. Custom chambers is just around the corner from me and I'm going round there tomorrow to ask about rolling up some steel for mine... which I'd weld up me own self, so I'll get you a price. If he needs a bike to work from my mate with his load of such might even have a GT185 I could borrow.
  11. I was building condenser microphones years ago using tiny little military spec valves and did the mesh thing for those but what I've got was chromed or stainless... though maybe I do have some brass somewhere. Hairy pig... actually Goat is the one isn't it though not Angora, just plain shaggy bush Goat. Now I'm actually aware, as in the sun's up plain grass fed cow with hair intact riveted (brass with aluminium washers underneath anodised blue!) will do fine. Pig and Goat are open pored leathers whereas Cow isn't so it's much more water resistant. Now I'm thinkin' about a Suzi Wolf 90 front end as they are the same fork diameters and width across stanchions and have a larger diameter brake... except the one I have hasn't the outer case with pads and speedo drive and the lining is almost all rust as is the rims and spokes. The back wheel might fit too or at least the sprocket which is drilled and smaller. Back to the handlebars now as in cut and when filed... welded. And I know this is on the wrong side but it's the oil can I'll use once I find some clever fellow who can actually weld aluminium. I was going to cut the back off it and put a flat across but seeing it goes into the battery hole I can cut another hole in the opposite side and bang out some steel to fit in which means the aluminum welding is just three small tube spigots for tap and level clear pipe. Plus I get to use some rubber and some bit's like below which are used in motorcycle packing crates to tie down the sickles.
  12. Actually a Rat skin seat would have to go on the back burner as it'd take absolutely years unless I set traps down the back where the water is as relying on the cats just wouldn't work and if I did it'd be mouse bodies without heads and they'd be finicky as to skin. Had a good day yesterday pulling it apart a little here and there thinking about what to fabricate and how to fabricate it... whatever it is. Basically I want to make as much use as possible with what I already have and today, when it gets light and I can make a noise, I'm going to cut up the handlebars and weld them up to be lower and more forward. I've just finished going through all the 'Girl with the Dragon tattoo' movies and reading all the books again and I'm about a third of the way through the last one and so may actually go for the seat covered in leather with a dragon painted on it... maybe even on a woman's back. One thing that's kinda head and shoulders above all the other ideas is that the backbone frame is the only thing that gets kinda lavishly painted, oh, and the seat, so the tank etc keep original paint with the rusty bits cleaned up and clear coated but the frame is bright blue and then loads and loads of Gypsy caravan decoration is applied in orange and green, or maybe I'll get frightened that's too much and go for lighter shades of blue. Actually the seat might be an idea I've had for ages which is to have holes in it so any upholstery has to go inside the holes and get glued or pinned in to the base 'cause theres only really ones hip bones at the bottom of our ass which actually need support but I wouldn't go to the point where it's just two small circles of padding as in one each side. Just went for a walk and had a look at the well rusted Wolf 90 I got from Japnut a few years ago and theres a slight chance I might be able to use the wolf wheels which have significantly bigger brakes... hmm. These are the pedals I got off some most alloy Honda years ago and they're a little high but that's where an available hole was. Passenger pegs will most probably go where the lower shocks mount. And the silver thing atop the motor is an air box from an earlier Suzi and theres the exposed fork springs which I quite like... and looking at the wolf it has much nicer spring seats. Theres also that hole in the side of the motor with the exposed electrical gizmo and I'm thinking a bit of brass over that with cutouts and a reasonably fine mesh behind it but I'm wondering about all that charged air around it bringing in dust and shit to plaque it up and I wonder if some clear resin might help as a window?
  13. That's just come to me, Rat Skin seat, as the noble pussies, one of them, deposited a fresh kill just outside the door and a few years ago we had a few up in the attic and I trapped a bunch and as I'd see some craft work where someone was farming rats in the ceiling and then curing them, the skins, and making little rat skin pouches. I had a go myself and spent a few hours sharpening up knives then divesting the little dead bodies of their coats but left the skins too long in the old tea bags solution and they rotted. I got this yesterday and I'm hugely chuffed as I'm so poor these days even the Mira is getting expensive to keep running so hooning about on a little beasty like this with a nice expansion chamber as jewellary hanging off one side really appeals to me.... and it's be so thin going between the cars on the motorway parking lot of modern Auck will be ton's of fun. Good golly, I just got my own joke... Something like this but no shine, can't be bothered with shine, so ratty and if it's got a rat skin seat... Oh, how cleverly Ironic! Custom chambers is just down the road, at least he was last time I looked sideways in the vicinty, but I had a word with him ages ago about just using his service to get the specs right,'cause I don't know shit 'bout designing 2 stroke expansion chambers or tuning stuff, and his foldy apparatus to assemble all the steels then I'll weld it all up and he was cool with that. First things first though and a clear out of the working space and bringing down the box of collected odds and ends and whether I did keep those rear sets from an old 250 racer style honda and which tractor headlight will look good.
  14. It has been a very long time. But yesterday an LJ80 chassis was dropped off and today I started taking it apart. I kinda got side tracked when I realised I needed to build another good sized shed to do all this stuff I ended up doing a bunch of landscaping work on the property as a preliminary to sheds and that's just ended up what I've been doing. In the interim though I've done some graphic design for Steelcuts in Onehunga and have a credit for 250 bucks worth of steel plus I have a load of building work over on great Barrier coing next moth so will finall be in a position to throw money at these ideas. This thing is well buggered but it doesn't really matter as I only really want the bits to build the frame around and will get good stuff later on and it'll be a 4x4 hillclimb car sitting way less than a foot off the ground, I'll use the 1000cc engine as it's well canted over so if I set it to the right of the centreline, where the driveshafts go, weights should end up quite central. This means though that the driving position will be on the left which is kinda weird but it's a racecar so it doesn't matter. Transverse leaf springs and four bars front and rear.
  15. Man, that is absolutely brilliant!!! I fucken love it to bit's. If it was mine and I haven't looked into the drive train, which I would have if it was mine, but what springs to mind is a 2CV engine or at least something comparably ancient but well engineered... even a imp engine would be well interesting. Another possible is something like a really weird subaru van I had which was from the 70's and it had a transverse three cylinder sitting out the back at a big tilt... that'd be neato too. You got weird, are going weird so why not keep weird top of the agenda? Eastern Euro peasant rat rods rule!!!
