Secondary spring pocket machining

[ROCKERDAN]

Got hold of my guy here, so gonna take sheave in for pocket machining.

I have a good idea how much I want to take out, but want to get consensus from guys here that already have done theirs.

So how much are you guys removing on the sheave pocket?

thnx

Thanks Shag for quick response, on my way over to his shop soon!

Im thinking I want to massage the tang hole after machining, to create a nice seat so spring sits flat.

Sheave dropped off at machinist......

.070 coming off(1.77mm in metric terms)

I'm on the fence permanently changing the secondary so have it shimmed for now. What happens if Dalton or TPI come out with a better spring with more force and one less coil? Will the deepend pocket then be a problem?

cant see it making much difference, its only 70 thou....(1.7mm)

I have setup my doos with compression springs with and without the delrin type washers(more then 2mm in total) on each end of the compression springs, and they dont change the overal setup much at all.

On a torsional spring the side pressure has even less effect then a compression spring, so I dont see it making much diff. And now I can wrap to 6/1 for a snappier bottom/midrange.

Hey guys just wondering how much travel do you have left on the sheave shaft where the helix bushing slides on, on mine it looks like I only have a half mm left as it looks like machining my pocket wouldn't gain me anything. I'm thinking I may need to do gears rather? Silly thought what do you guys think?

Please keep us posted on how your new G-Force set up works out.

Looks mint.

The quick torsion adjust is VERY nice to work whit . You can change the "leg angle" on the fly whitout removing the cam........


41-37 not sure yet for "stock sled" stock weight was 72,6gr 72,5 and 72.3 gr........
rpm was to low8200-8300 on long pull in realy soft condition...

OeM have 4,5gr rivet in each 3 hole.
I have replace the first one for the 2,44gr rivet. The 3 are now 70,5 gr rpm Torsion at 65degree
187gps 193 speedo 8600-8700 rpm
did not test this in every condition work in progress

 

[ROCKERDAN]

very nice! I was hoping to see someone try the new Gforce adjustable HELIX, cool cool design for guys who like to test!

Can you tell me the range of adjustability with that? is there a min and max ramp angle? Can you go to a reverse angle(Shallower then steeper)

Do you have to buy more "ramps" for each angle you desire?

Please let us know how it works!

I read somewhere that Dalton said machining the helix wasn't necessary.
