The Lounge / Altoona, PA trails?
« on: March 15, 2016, 04:47:08 AM »
a long time ago somebody here posted pictures of some trails in the woods near the lowes in altoona.

I lived there when the lowes was first opened. The grand opening was like a fair - spotlights and chainsaw carvers and stuff.
Then I saw the trails in person in 2002/2004 when I was back visiting, then saw them posted here a few years later.

There's some sort of Park designation/symbol right by them on google maps that says "Altoona Trails" but I don't know if it's just walking paths now or what...   

Do they still exist?

The Lounge / currently salmon is worth more than crude oil

I GUARANTEE you they're going to fuck this up. 

Meanwhile they're shoving natural gas up our asses before we even have a supply line or any infrastructure, far-exceeding any of their cost estimates, criminalizing woodstove users, and taking crazy aggressive actions against people using the waterways or doing anything that has to do with fish...

The Bike Shop / clutch flange diameters?

I've got a chance to get to a shop today to get some spokes/a rim, but I don't know what rims they have, and I don't have the hub with me, so I figure I should just need the width/diameter?


The Bike Shop / anything wrong with running a sprocket like this?

I've never paid any attention to or used spline drive sprockets, but I assume having a spacer between the arm/sprocket shouldn't cause any problems?

it'll be a little different when I'm done, but I'm pretty sure I need to space it like this to keep the driveline straight.   anyone else done it?

The Bike Shop / retro sprockets
« on: November 14, 2015, 03:38:43 AM »
odyssey, haro, kink, profile, merritt, colony, primo...

who else is making tiny reproductions, or just near-look-alikes of sprockets from the late 90's/early 2000's?

The Bike Shop / anyone use flatware forks?
« on: November 11, 2015, 12:40:42 AM »
what's the biggest tire I can use on them?  I don't know if it makes a difference, but they're the 28mm/chase gouin model...

The Lounge / is it true?

that I can somehow pay for an upgraded account with access to old posts?

The Bike Shop / acid-etching a screenprinted sprocket?

I saw this a few months ago...

Acid Etching Custom Head Badges

...I was chatting with a friend and our conversation migrated over to PC board etching. PC board etching has been around for awhile (I’ve etched boards well over 20 years ago) and widely practiced by electronics hobbyists. I then did some research and found examples of people using modern day etching chemicals (muriatic acid) to etch aluminum. That’s how I was going to do it…

...I printed a sheet of my images onto the slick backing using a laser printer set to print on “overhead” sheets...

... I cut out an image and placed it over the badge (toner side towards the badge) and then taped it (using painters tape) on the back...

...The idea is to heat up the aluminum so the toner will dislodge from the paper and adhere to the aluminum...

...The basic ingredients you’ll need are 31% muriatic acid (hydrochloric acid), 3% hydrogen peroxide and baking soda (to neutralize the acid when done). Protective gear... You’ll also need a measuring cup and bowl for the etchant...

So I got a blue shadow serpent sprocket, planning to scrape off all the text and the stuff around the sprocket bolt, etching just the snake...

but i've been sitting on it for over a month now because I really don't feel like trying to find muriatic acid... I just want to use some oven cleaner spray, or at the most a citric acid powder bath, but I don't know if those things will melt the screen printing off before eating the ano/aluminum...

Anyone have experience with stripping ano off of screenprinted parts?
