I found this today while surfing the web
I thought I would post a link for all the youtubes

That man tickles me. I have enjoyed YOUTUBE more on the LCD blue-ray television more than ever on a computer.
The skateboard wheel he uses to "cross" tipped lines on the beadroller without deformation.. anyone know a brand and "hardness"?? I looked on ebay and they come in different hardness.. some are hard, some are soft. We have not ventured into the "realm" of local Skate shops.. (one in my area)
I had a truck load of that mirror stainless at one time, "MIRRORS" for motels and prisons. I am playing with scraps now.

I watched every one of those when i first started learning about metal shaping. I like his accent! hehe

No idea what Lazze uses for hardness, and I'm no skater - but - I'm told that you can judge hardness by the color. Darker the color, the harder the wheel. In general, that's proven to be true with the ones I've picked up at garage sales.
David, My skate wheel is hard. Like as in a roller skate type wheel.
It works, just not as quick as softer wheels I have used at other shops.
They are cheap (or free in my case cause the kid broke his board!)

John, I thought the same thing until I check out Ebay. It does matter if it is white, black, red or clear they all seem to be 97-99
I bought 4 wheels for $7 shipped, after I get one machined to fit and give it a try. I will let you know how it works

I use a red-poly caster from Northern on my tipping wheel.. it came from Northern, is much harder than the expensive "red poly wheel" that came from *'s over in Alabama..
FYI: the softer one would not crush-shrink tucks like the harder one here.
The harder roller crushes and deforms the tipped lines as it crosses them.
Let us know how them ebay wheels work.. and which ad it was..

I helped one of the norwegians with dies for that.
Heres a test piece he made after I left..
Dont know if he altered them after I went home but this is how we made them
The green skateboard wheel was very soft.
01-03-2012, 02:16 PM
That's the effect I want. Thank you very much. Looks to be red urethane backing up the "tipping" washer and a very soft wheel to sink into.. will degrade and go away (use up) very fast like soft compound racing tires.. (if they are 4 for $7 that is fine thou)
(I know you are from the frozen North, but it's cold enough here in my shop for metal to stick to the skin) It'll be tee-shirt warm by the week end.
Lazze, has gave me enough education off his youtube videos to need a "thank you" too.
He probably has so many "metal groupies" I could not get close enough to thank him in person.

You're welcome DC.
If its cold you'll cut the urethane easier :D
Im actually in Australia now and would be happy to trade back my nice winter back home.Landed in Melbourne to days ago in ,40 degrees C. Hate that dry heat. Spent 3 weeks in 35 degrees high humidity in north Queensland, felt much better there.

Rick, Anders, Ebay still has the $7 skateboard wheels, free shipping.
I just bought a set of 4, they also have them @$5.
Thanks. Will let you know how the Anders-special works out here in Gawgia.
01-12-2012, 06:45 PM
I talked to Lazze a couple of month's ago and he said the durometer is about 60 & 80, I bought some of each. Machined a steel hub then machined the center out of the wheel & shoved on to the hub. I also have a large washer on each side to help keep the wheel from totally falling apart so far it works well.
01-13-2012, 06:18 AM
Next question? is it best to "freeze" them overnight before machining? (Anders got me to thinking) like cutting up deer meat, you want it stiff enough to not "turn" under the edge. (colder outside right now than inside my freezer)
Like normal? "ten hours of thinking and ten minutes of doing".
01-13-2012, 09:29 AM
I needed to turn down a foam roller on a steel bar shaft. Impossible! Not.
Took my wood router and made an adapter to fix it in the toolholder. A wood router bit at 30 000 RPM made the roller no problem. This should work with any material that is too flexible to be turned using a fixed tool.
The cutter hits the foam at such high speed that it does not have time to flex.
01-13-2012, 09:36 AM
I did not have any problem machining out the center I just used a boring bar turning about 250 rpm & slow feed thru with several passes getting to the diameter I needed to a hand press on fit.
I just "bored" my skate wheel with a step bit and my hand drill :lol:
Are you guys over thinking this operation???
01-17-2012, 12:05 PM
These skateboard wheels came in, Light green, not translucent like ones in photo. I can not "budge" squeeze them in my fingers so they are "hard". Feel like uhmw in hardness, are just doughnuts machined in a lathe, not cast Urethane or .... Also, diameter, about two and quarter inches or so..
So, save that $7.99 till we find the right "ones" on ebay..
(Aww the joys of trying to recreate something done in VIDEO)
I'm back to shopping unless someone can point me in the correct direction.. my search will say "soft" wheels this time.
(you know my European friends can't get good cornmeal to make southern cornbread either) and I figured out that "why"... different meal.
My wheels are hard and works fine. I use a upward lifting action when I tip my flanges.
Wouldn't a soft wheel just create a V?
01-17-2012, 04:31 PM
I talked to Lazze this moring and he told me that he uses a 60a rated wheel.
I talked to Lazze this moring and he told me that he uses a 60a rated wheel.
And what roller skate or skate board can I steal that from??
01-17-2012, 05:13 PM
All the "soft off road ones" on ebay are 78. I am still searching.
Next trick, perhaps a rod of urethane to drill.
01-17-2012, 05:20 PM
I picked up a pair of roller skates at a thrift store and pulled the wheels off. I removed the inner hub and pressed the outer urethane wheel over a new hub that I machined for the bead roller. The wheels were blueish green, it that matters.
01-17-2012, 05:41 PM
Color does not seem to matter with the skate wheels. These green ones are hard. I was hunting "green ones"... didn't work.
Urethane blocks, sometimes it does. I just priced some 60a rod, enough to build several of these. BUT, I've never machined it and machining "soft" stuff is kinda hard, it don't want to cut curls but tear hunks out.
Why I was thinking putting it in the freezer might be a good idea.
Overthinking again huh Chris?? I hate screwing things up because I didn't ocd them tho.
01-17-2012, 05:51 PM
I gotta ask . Where does uhmw fall on the durometer scale ? i bougt a 2.5 "stick of it from MMcarr , and machined for my lower roller for tipping flanges . seems to work well !
01-19-2012, 11:33 AM
here is a link to the roller material
the part number is KPS-1000U 0210460
1" ID 2-1/2 OD 2-1/4 long
01-19-2012, 06:12 PM
Yes.. I just ordered these Skateboard wheel set. super soft.
Translucent green, with bearings. I can always find something to use them bearings for. (here's hoping they are the same as Anders posted.)
The Skate-board scooter wheels I bought to do the "tucking" roller? I mounted them on the rear of a buddys wheel chair to stop him from going over backwards.. "wheelie" bars.. Ha.. crazy old coot.
The rollerblade wheels held up under pressure but the larger wheels fractured. They are not all the same.. some are junk.
NOW on with the show.. I got some "stainless" trim to make.. and I need to "do this Lazze" trick here in Gawgia.
02-15-2012, 03:04 PM
If this video was "new" I'd have a attack of paranoia thinking Lazze has a link to the cameras in my shop. (making some custom trim for the hot rod)
ie: what I have been working on, in addition to a few mechanical things..
the green wheels Anders K showed you are caled '' loong board wheels'' they are realy soft
pictures are taken at one of my Norway Meet's Anders K & Jon-Hroar kept going on i the shop til about 2'o clock in the night :lol:
a frend bought them in New York
02-16-2012, 04:53 AM
Seems the soft ones are listed on ebay as longboard "offroad" wheels? perhaps cause they can run over small rocks and things? The smaller harder cheaper ones are listed as longboard also. There are several diameters, and mostly the hardness is listed as 68.. so?? no clue.. except I bought them twice to figure it out.
I think everyone with the chemicals are "casting them", I have a link to a polymer supplier in Chattanooga Tn.. they like to sell in drums thou.. prefer to sell train cars full of product. I see a opportunity casting hammer-pads to stretch on for someone. You can stretch like heck over a piece of this.
Nice thing? wheels come as 4 to a set, so you got spares. I still have not tried machining them in the lathe yet.
MY PC has lost it's flv-youtube sound.. I got blue-ray and the big television now only to watch Lazze on there.. till I figure it out. (again)
02-16-2012, 08:06 AM
How it's made or Factory made just had how they make / cast S/B wheels. I missed the beginning, saw the solution pouring into s/s cylinders. It was from 2010, so it will be on again, again,and again.... tt;)
02-16-2012, 08:21 AM
Kinda going off on a tangent from Lazze.. but..
The castable polymer I have messed with comes in two parts.. mix 50/50 company name used to be "synair" in Chattanooga Tn, thou they have been purchased by a larger company. mix it, pour it into a mold with "mold release" applied.. and it hardens. The last one I messed with was a por-a-mold for rubber mold casting wax copies.
They also make a cast-able "hard" plastic.. It'd be great to make hammer heads and other things.. you can drill, machine, tap it and it holds threads like aluminum. Por-a-kast if you want to find it at smaller hobby suppliers.
All this stuff has a shelf life, probably due to it just being a 2 part mix. All mine here has went bad with age. In my opinion, this is a way to make "instant tooling". Hobby site.. small quanities.. http://bare-metal.com/Pathway%20Polymers-Por-A-Kast-Polyurethane-Resin-Casting.html
Anyone want to cut and paste this deflection of thread into a new thread?
02-17-2012, 03:34 PM
Check out this site. http://www.reynoldsam.com/ I have purchased urethane from them and it is all good quality. They also have some instructional info which is good. Not the cheapest but you can buy small quantities. They also have samples, pre-made, of everything at the stores so you can see exactly what you want.
02-18-2012, 05:11 AM
Neat link, a "urethane" cast hammer pad.. would work great to throw over a steel table.. you could stretch like crazy. They sell a variety of " hardness" urethane to cast, a baking sheet-pan would be all it would take to make some neat pads.. (put the no-stick to it, or it'd be part of the pan from now on)
I asked Ben (Pedalcar) where he got the urethane under his bam-bam hammer.. Not seen a supplier locally.. you could of course cast your own with this company's products.
02-18-2012, 07:24 AM
Here's a link to some castable urethane from Devcon.
I used this to cast drive rollers for a pulltruding machine. I think we got it from MSCdirect.com. I think it was called Flexane.
12-20-2012, 10:06 PM
I found urethane of several different durometers on E-bay. A few as low as 60 duro. If you get lucky you can find short pieces. Urethane seems to be the only plastic that goes this low. You have to be careful of the longboard wheels, they are usually over 2" in diameter. good luck!!!!!!!!
12-23-2012, 12:24 PM
Go to mc master Carr and go to the drive rollers. You can find any size, width and hardness you need. They cost a little more, but there will be no machining needed.:merrychristmas:
