Slalom

Nice, I want to put this in my Splitfires which have Randal baseplates and have an adjustable pivot in the hanger but lack that wide shoulder the Randal hanger has to push on the bearing. I think I need more of a cup bearing or to change the pivot somehow. I know some Splits have pivot bearings, anyone got one with a pic or description of how it is done?

Bump: Sutherland Sunday??

Marek, Fitz hooked up Bugs and I with spherical upgrades on our splitfire rears (randal baseplate), so simple it was ridiculous, just ploped in perfectly and the ball screwed easily into the hanger (fitz may have machined the thread?) Thanks Fitz!

i have always wondered what difference it would make in an airflow rear in the pivot, they use a weird pivot though it isn't a ball shape

...penciling in tech talk time with Fitz this Sunday!

Boz,

airflows use a tracker rt x baseplate with aa normal tracker pivot cup.

The pivot itself is a 8mm, 1.25tpi cap screw that has the OD of the head

turned down to 11mm with straight and parallel sides to fit the pivot cup.

I guess Mr Airflow figures with a near 0deg kingpin setup,

when the hanger leans the pivot only rotates in the cup,

it doesnt lean over in the cup like a steering hanger pivot does,(hard to explain).

so you dont need a ball end pivot.

.or they're cheapskates.

And the cap screw screws into the hanger itself and uses a jam nut to secure it

A ball end in a spherical bushing doesn't make sense to me as the ball will just kind of flop around, maybe i haven't followed the description right. Ball end in a cup would be fine. I was working on the theory that the ball doesn't support any weight - the bushing does that.  The shaft can move freely through the bearing so the pivot just guides the hanger.

Love to get down to Southo on Sunday but can't make it this week.  Any chance of something more central?  Someone had a place in rose bay or thereabouts- can we try for that again?  otherwise we could host one on the sunny side of the harbour. Craig?

anyone who remembers slalom comps at Bangalow might be interested in this.

So all we will need is someone to talk em into adding a slalom race to the program!

See you there Sunday dudes!  Doin a rain dance...

Fitz is the mod king!

craig i think mine is the 95mm width but i'm sure guff had the 110 and could fill you in

guff is part of the BMB crew, i'm sure you will see him soon enough at a race. PM him on here and see if he is willing to sell his airflow i think he has upgraded his trucks

Cheers Fitz, I'll see how the nylons go and switch to steel when they wear. Don't you find that the al hanger wears in the steel spherical?

My modded Bennet Hanger came in today. Great work from Griffin Skateboards is all I have to say and Thane has great customer service. Its space-able 95mm-110mm, polished pivot, machined bushing seat and a derlin pivot cup cost $87 shipped for the hanger - I wish I had more money to throw down for the ball pivot but at $75 its too expensive. Pictures here http://www.skateboardracing.org.au/photo/img-0667-1?context=album&a... 

Only regret was not buying a derlin pivot cup as well!

Finally get the grennet hanger stoked ask but brother has misplaced the baseplate - typical...

It seems gasolene and base oils have little effect on delrin, so vasoline and other petroleum greases should be okay to use. Cheap and easy to find locally.

You can also buy synthetic grease from bike shops which is probably what "Griffin Grease" would be. Cost a bit more though.

Here's Duponts spec sheet for Delrin

I didn't get griffin grease which just seemed to be a kind if white lithium grease to me. Though I did regret not getting the derlin pivot cups should have done more research. Will be getting my randal with a spherical in the hanger will make sure to put up some pics.

I wish to sand the pivot on the bennet more as there is still a ridge of excess material down one side of it. Should I just use 600 grit and work my way up to 1000. What's a cheap end product that really give alum that chrome shine?

Mother's mag and aluminium polish.

Thanks for that Cas.

The Modded Randal DH hanger by Gibs came in today. Workmanship definitely isn't on par with the grennet. The spherical is simply JB welded into the hanger. I would take the whole rig out for a ride but the bushings I have won't fit. Anyone have any tips on the best way to shape a bushing into an elim style?  

Craig I don't believe for a second you have any shortage of doobies.  Got time to meet up for a skate over the weekend? - I got a 4 day weekend to make use of.

Cents, If you mean yo need to take out some of the centre of the bushing

to clear the innner race of the spherical, use a mounted grinding stone on your drill.

Wear ppe and use either angled or round stones to get the shape you need.

Thanks will buy one up. Though I may also just get some super hard elims - they work very well in the DH hanger. 

Just make sure they clear the inner race

or they'll foul as they (and the hanger) try to return  to centre.

Tried it out not too long ago. Seem to run fine. Very jittery with the derlin spherical but feels very precise. 

Heres the modded DH hanger:

I've just started slalom and would eager to have a session around Willoughby netball courts near hopkin? Is anyone there that I could go with and teach me a few things?

Yeah thanks craig!

Finally got my board set up alright. Got a chopped up 120y with bennets ( White Khrios in the front and yellow in the back) and 66mm zig zags. got a 17 degree wedge up the front and a 10 degree de-wedge at the back. What do you think of this?

Getting a tracker rt-s soon for a back truck.

Trackers are good value and work fine for a rear truck. If you have Randalls or compatible randall stuff for you downhill  and free ride board you might prefer to use a narrow Randal hanger for a rear.  You can then avoid some wedging by just using lower angle baseplates, plus you can switch around with your downhill stuff.

Then if you need to you can  narrow the width further by just turning your offset wheels around the other way.

I have just modded a randal 150 down to 104mm and I have been running it at 56* as a front truck with a tracker rts dewedged 7* on back. This set up feels pretty good to me but I know nothing about slalom. Would I get more traction from having a completely dead randal in back rather than an rts?

Hey Cas,

You can make either truck dead by locking it down with rock hard bushes.

Joe Eagle went for a spontaneous cone session today. He hasn't ridden slalom in nearly 4yrs.

He had 139mm IndeeSZ front and back and initially it was suicidally turny.

I dialed  in his rig with some bushes out of my personal stash and it tranformed the whole setup.

My advice is you have both, try em as a rear truck but lock them up with hard bushes. It's much easier than trying to dewedge a truck.

Randals are great as a rear but unless the axle is centreset your wheelbase will shorten up making your rig lose a slight amount of stability.

I forgot to add that after our days riding hey was getting clean runs, when to start off neither of us could even make it through more than 5 cones on his initial setup.

What are the chances of a 101 cone challenge at Newton's this year?

My guess is that it needs someone to collect $1 or $2 per run, and log the times, and a spare bit of track, say Mountain Straight, between the bus drop off and the pit area.

Cones are not a heavy as bales, and it could be a bit of fun for everyone. 

Cheers Fitz, I'll give it a go.

Anyone got a set of slalom trucks they are not using.

Could you let me know what they are and what they are worth to ya or i would trade for a new set of 50 degree calibers.

i am making the deck now i want the trucks to GET MY WUG

WIIGGLE ON!!!!!!!! oops

Wuggle is how the Kiwi's do it :)

Budget solution.

If you have a 35 deg randal plate or equiv' you can buy a 125 randal hanger from boardshop and that will take care of you back truck. Use your hardest barrel bushes and crank it down tight.

Make me an offer for my 4.1" Bennet truck and there's you front sorted. PM me if you're interested.

So long as your deck is flat without kicks where the trucks mount you won't require any wedges.

Start with at least a 20-21" WB

65-70mm wheels with sq lip.

You could just buy a 35* plate and run it with your paris 50/35. Not much of a slalom setup but you'd do a lot better pumping than wedging a 50* plate. Throw some 98 venoms in the back and some softs in the front and you'll get it pumping - pretty much how I started off but with randals. Though wheel bite would be an issue. Wouldn't recommend wedging the front past 60*.

Only reason I say boardshop is bcause I know they do hangers only.

Even though he doesn't have a bricks and mortar shop Tony isn't such a bad guy. I met him a few years ago. I prefer to stay out of the political bullshit other have.

I used to run a 4.3 bennet (7* wedge) and a 35* 125 (wedged to 20*) randal setup. Don't think you could do much better for the price.
