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.

Forget buying bike parts on Ebay, buy the whole shop!
http://cgi.ebay.com.au/Bicycles-and-Hobbie...1QQcmdZViewItemHey 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.

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.

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.

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?

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.

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!.

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
Jun 25 2006, 12:36 AM
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.

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
Jun 25 2006, 01:32 AM
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.

Jun 25 2006, 03:21 AM
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 :/

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.shtmlhttp://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 ?

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.

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.

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.

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.
