Fractured Lacerations - Build - I Broke my Knife!

[Customize IT]

I got 2 now a little harbor frieght deal and that one could run 2 different medias.

Still want to build a pint booth and pick up a english wheel, shrinker/strecher, planishing hammer, and a tig welder but, the list is getting shorter each day?

Man to be able to have to sheet metal tools thou!

Got her welded and off the jig. Frame weight was 95 lbs when measured with bathroom scale.
Now to build a front end.

[Customize IT]

Well charting new ground for me need help here?

Started laying out for the front end. After talking to kyrmis about what to do to get the bike ready.

Raised the frame up 1 in in front.



Found the neck angle here. 46 degrees.





Tried to do your large trail link angle find.

Put string at start of ground patch rear tire.



Set trail at 2 in ground trail.



4 in of trail



Then the string from the rear to the front axle and got the angle.



Recreated this in the drawing but not sure the rockers will look as i want?



I used the 90 degree rule but this gives me really long rockers at 4 in let alone 2 in trail?



After talking with Jaxon about spring ratios and he recomended to move the forks out from the trees and also to move trail forward. And that I needed a better rocker ratio I did as he suggested.

Came up with this at the 90 degree rule and 3 in real trail. The rockers also have real close to the ratio he said I would need.



This is the motion print of the brakes to see if there is a problem?



Anybody need any other prints or have any input Please help! It is a blank slate I can make 100 prints until right?

it looks good to me.

THANKS!!

That is all I need!

Now to build it!

[Customize IT]

Got the neck shaft ready to make trees/yokes for.

Cut the lower tree/yoke off with grinder.

Turned until I could tap the bearing off from back side.

Turned the weld off for lower tree/yoke.

Then turned between centers until it peels off.

Now to order new bearings to press on and make trees/yokes.

I got my neck bearings ordered should be here about thrusday.

Got the rough width drawing done and figured out all the distances for componets.

Got all the parts for front rockers and spring units ordered should be here monday or tuesday.

Also made the rear axle spacers but have not got pics.

I need to work backwards on the front end and get the front wheel and rockers made with the brake floating spacers done. That will tell me my final tree width and can then build the trees.

A ton of work in such a short time. Nice job, and thanks for all the close up shots. Great looking forks.

Thanks this is how I figured the spring rate constant in lbs of force?

Gary say in the handbook that a bike with 45 degree rake will have 36% of weight on front wheel.

I am guessing the bike to be 500lbs or so when done and a 270 lb ya I know right rider. I weighed 185 when I met my wife but, anyway.

That is 770 lbs it has to carry. So multiplied that times the percentage of weight on front end.

770x.36=277lbs force
Then divide that by 2 because 2 springs and get 138.5lbs each leg.

I ordered 150lb springs we will see what happens?

I can always heat with torch the springs to get them to loose some force?

All the spring places said to stage up one size also.

[Swamprabbit1]

Sounds great.
looking good.

I have got pics of the rear axle spacers instaled.

I got the spirder spring contraption thing done

Also got the new neck bearings in.

Love that I-beam frame. The bike looks like a machine tool, I mean that in a good way. What kind of finish are you going to use?
