hey would anyone out there have a 36h crome araya 7x rim, or be chasing one, and anyone no anything about polygon gyros. I was wondering the mongoose frames don't have any holes in the ht st or bb for the heat to escape when welding the tt and dt, I was wondering isn't that normaly needed, atleast i heard thats why the holes are there, I'm not very knowledgable about welding so if anyone can shed some light on this, It'd be much appreciated, otherwise i might start a topic in tech.

great pics James - well done. how about a pic of your se score??

Dirtboy, do you guys have night clubbys in winter?? I love night riding but its just to damn cold for the kids this time of year.
HowardinOz
Forget buying bike parts on Ebay, buy the whole shop!
http://cgi.ebay.com.au/Bicycles-and-Hobbie...1QQcmdZViewItem

Hey Bully,
I believe the holes are for when the frames etc are plated, ie chrome or nickel.
I had some stuff Gal'd one time and had to drill small holes in it via the platers instructions.

Howard
HowardinOz
On an off topic note:
Glenn, do you know of anyone who has supercharged a 'Holden' Suburban?
Do you know of any forums where they discuss such things here in OZ?
Want to see what someone else has done to overcome the A/C issues (ie, it's in the way).
Have a day off so I'm going to mount the compressor...the rest will take some custom fabrication.

Howard

interesting that would make sense but the why drill the holes in things like the ss braces, wouldn't that just be a good place to collect mud and water in then, and thats on a painted frame.

those are the rims I got

I got a photo of my new race frame frame now its built up, and i was here for a day.

Cool bike, are those Oddysey Black widow cranks? I might rebuild this Mosh I have too. I need a new school racer. No really I do!
COASTY
Howard. That bike shop belongs to Darren May. He told me he was selling it. he's a good bloke. I raced against him quite a bit in the early 80's. He was a factory Profile racer. And the only guy I've seen beat Stu Thomsen at Liverpool.
ps I'll have a look around for the suburban issue too. Maybe the LS1 forums? What motor do they have in them?
COASTY
Howard these are US sites.
suburban forum
HowardinOz
Thanks Glenn.
The Burbs have the Vortec 5.7L in them.
I specifically need to see an Aussie 'Holden' done as the A/C and Brake Booster are on opposite sides to the US version. That's my issue. The Whipple kit I have is designed to bolt straight on but the A/C is slightly in the way of the manifold coming from the back of the compressor to the throttle body.
I've removed the manifold and blanked it off for the time being and I'll install the compressor and see where to go from there. I should be able to make, or have made most of the custom gear at work out of stainless.

Howard
COASTY
Oh yeah I get ya. Everything is arse about. I'll look a bit more.
On another note, I can't wait to finish this monster. It weighs a ton and thats without the motomags on it yet! or bars. I'm really hanging for the bar risers though. I still have some painting to do on the bars and get the seat organised. It's gonna be sweet to ride. I had real issues with cranks. These cranks have a 48 t sprocket so I'm going to have to find a bloody big rear sprocket!.

Looking good Glenn.
Did you see the Yamaha motobike on the bay for $1000.00?

Howard

PK number 3. Will probably do a retro build but it will be a while. Should finish numberr 1 and number 2 before starting number 3.

bullyhotrod86jh
haha yeah just one more build, I'm only doing 2 until you have 30 going at the same time and are saying the same thing hahaha ahwell its all in good fun.
yeah glen odyssey black widow phat cranks with the double pinch bolts
S&M race frame
odyrace 41 thermals
profile 44t disc
dm24 rims 36h laced to formula sealed hubs
fusion alloy bars
avid speed dial 5 lever(or something like that)
velocidad
Glenn: what style of cog do you need ?? are the motomags like a normal coaster brake hub sprocket?? I have a selection from 24" coaster wheels that might suit ok.
COASTY
I just put everything away and cleaned up the shed so I have no idea what style of sprocket they are. I'll go down there and look in a min. I'm looking for a 17 or maybe even 18 if they make them that big!
I still haven't been able to post your sprocket yet. I work harder at home than i do at work! i'll try again on monday.
Joel my black widows are the first model.The sealed BB cost me $140 !!!

Where'd you pick the PK up James?
Hard rubbish collection? (wishful thinking hey)

Howard
Jarvi
Howard I got it from a guy at the Eastfield BMX club. See what happens when you start racing.
COASTY
Good score James. I'm gonna get me one oneday!
mark the sprocket for the motomags is a Bendix 76. Same as a Tuff II (some of them anyway)
Jet Black
I think an 18T rear bendix sprocket would be the best gearing for your moto magged mono shocker. Shouldn't be too hard to find as long as you can measure the cog ID & count how many bumps are on the inside of the cog , 3 probably

I have no gearing charts near me atm (which is odd)

46/17 on an alloy wheeled BMX was a tad easier than the 44/16 standard.I never ran anything bigger than 46 on the front bitd, running 48/17 on a bike with heavy wheels may give you some grief in getting moving in a hurry from a standing start but should get you into a good cranking speed , pending on how much energy you lose to the shocks....ahh my gear ratio chart !!!

These numbers are for a 20 x 1.5 rear tire all the other larger OD rear tires don't have 48 tooth sprockets on them but should give you a good comparison anyhow.

Old trusty 44/16 52.5
Spin to win 42/16 51.3
Secret ratio 46/17 51.7
Alt secret ratio 41/15 52.2

Mono shock 1 48/17 53.9
Mono shock 2 48/18 50.9

Hmmmmm , yuk. You got heavy wheels on a heavy bike with suspension , try & get both a 17 & an 18 to test them out.
The 18 tooth should get you up & running quicker but the suspension may make you bounce around like crazy when pedalling , the 17 tooth looks like a cranker but may be more suitable to ride if you can work with the suspension
travel.
I now know why I never went above a 46 tooth sprocket bitd , 48T is a ***** of a number to try & slide between the ratios with.
Finding a 17T & an 18T rear cog should not be a huge problem for a bendix hub , long as you know the dimensions.

JB
COASTY
Yeah. It's got the 3 bumps like you mentioned.
KOSY-MOTO
Nice SE bike bro!!
velocidad
i'll have a scrounge around this week
mcam
I ran 46-17 bitd. Secret ratio was right. Most people around here ran 44-16, and dropped to 43-16 when needing a bit more acceleration out of the gate. I ran 46-17, or 45-17 for acceleration and spin. Worked pretty well.

46-17 is a great ratio. If I could find a DB turbo or Sugino Turbo 46T chainring, it would be going on my next build. At the moment, I'll have to stick with the 44-16 :/
Jet Black
Damm , is "B!A7ch" really an offensive word when used in context ?
I can semi understand Hal's FAQ guidlines on not using the 7 words you can't say on TV.

****, ****, ****, ****, [I tried to curse], Mother****er and Tits

refer to here.
http://www.erenkrantz.com/Humor/SevenDirtyWords.shtml
http://en.wikipedia.org/wiki/Seven_dirty_words

But when being used in context in colloquial conversation describing a bicycle part as a B!4tch seems appropriate.

BAH!

I got a 18T clip on 3 nub sprocket here , light surface rust, my semi precision digital G clamp measures the ID as 34.72mm does that sound right ?

JB
gazallac1
Hey Glenn, I've got some 2nd hand bendix sprockets up here. They are different to shimano, suntour etc. Different ID from memory, still 3 prong and look identical though.

Ok dudes, I've finished my first set of repro Bottema forks! For the moment I'll be doing only 7 sets to sell (4 off those are already sold). I'm doing 20", 24" and 26" forks. If you've "pre ordered" a set get in touch with me asap as I'll be making them this week. I'll chuck a set on ebay also. They look awesome and they come with decals and a JC stamped serial #. They are raw finish only at $160AUD per set + $10 postage to anywhere in OZ.
Here's some pix.

Pete Porker
Hi guys, haven't been round these parts in awhile, just been stupidly busy with 'life' and other endevours! I just dropped a brief note in the 'Gatherings' section about the Aus Gathering that we've been working on for this year, check out, catch up with y'all soon.
gazallac1
Thanks heaps guys!

Yeah, autocad and laser cutting is cool! If I had a cropper (punch) and a few dies I could stamp 'em out OS style! He he. Or maybe cut and file them by hand......not. The laser cutting produces almost identical cut markings to the stamping process which is cool too.

Nice one Pete!

I spoke to Pete today about the NSW 2nd Aussie OSBMX Gathering and I'll be moving my gig to January next year if that's cool with the Beenleigh committee. Keep ya's posted.
grub
coastvl: i have a 18t and a 20t cogs that may help. lmk
(they have the 3 lobes on the inside)

johnny chopper: those forks look 'fully sick!' mate and i know a chromer is melb that'll chrome forks for $40
also what is the measurement from the inner side of the dropout to the inner side of the fork
just curious for another disc conversion
COASTY
Thanks Grub. I'll let you know for sure mate.
gazallac1
Hey Grub, Thanks man!

The inner side of the dropout to the inner side of the fork leg is approx 6mm. If you gave me measurements I could make a caliper mount if needed.
HowardinOz
Hey Grub,
who and where is the chromer. I need to get my LG's done!

Howard
Jet Black
I think Hal will be checking his word filters after my last post , as to wether he puts me in the sin bin is another question , the post was done in "good faith" after I read what could & couldn't/wouldn't be allowed to be posted on this forum.

My apologies for the first uncensored word that appeared & even the other one that turned up.

You can never have too many sets of Bottema forks , I grabbed a set for a BIN price of US$150 off ebay the other day.
I'm sure there will be plenty of US ppl moaning about the JC replica's making their originals less valuable , market flooding etc etc but what me worry ?
Hopefully the JC Bottema replica's will end up on bikes that get ridden around rather than hoarded away doing nothing & seen by no one.

JB.

They look good Gary. Wish I had that kind of skill however mine is limited to pushing keys on a keyboard. Hang on, sounds like some of that is involved in your work as well...

I assume they are 1" threaded. Any plans to make a 1 1/8ths non-threaded?
Mattblack
Johnny couldn't you make something better appreciated like some CW bars lol

hey guys , is south australia in a timewarp or something ?? (yeah ok , i know its 20yrs behind) i have posted the pic on another thread too , i just got my quad frame chromed and a set of os CW bars ... $66 at CHROMATEC ! and getting stuff powdered here is $40 for a frame,forks and bars .

the US contingent pay $200-$300 for a frame to get chromed

the bike is not finished , still needs a headset, seatpost, pedals, stem, and all other obvious bits that are missing . but i needed to take it for a ride . check out the $66 chrome job on the frame and bars .
