1700 Nomad Trunk Rack-Results at end

[Sin City Stan]

This is a follow up from a previous post of mine on how to make a trunk rack. Some asked for pictures so I took allot.

Previously I made a cardboard template. Took it to work and transferred the dimensions to Auto Cad. I printed full size drawings and attached to the 11 Ga. steel with rubber cement.

Side Rails


Aluminum Top Plate


I center punched all of the holes and drilled them. Then used a jig saw to cut the side rails out.


Peeled of the paper.


Rubbed off the glue and checked the fit.


Had interference with the chrome trim and had to grind a bit off between the shock mount and first bolt hole. Then I used the metal rail to modify the left side rail. I blame this on the cardboard template that was not rigid enough.


Modified Right side rail.




Left side rail. We have a problem Houston. This is the first time I really looked at the left side. Silly me thought they were the same. But no, the left side shock sticks out 3/4" further than the right hand shock. ??? More on this further down.

Positioning the top plate


The bolts shown will actually bolt through the trunk, top plate and side angles.


Now you can see the left side rail has been shortened. Having no way to produce compound bends I elected to cut the shock mount off. There are still four points of attachment to the frame or the sissy bar casting which also attaches to the frame.


The trunk will be 13" tall. About an inch shorter than the existing backrest.


The trunk is 23" wide and will overhang the bracket 4 1/4" on each side. And yes, the saddle bags will clear the trunk by 3/4" when opened.


The finished rack.


Until I get the trunk and remove the sissy bar I cannot determine exactly how far the trunk will extend past the end of the bike but I'm guessing 2-4".

I still have to disassemble the rack and take a belt sander to all of the edges. I also have to buy/make spacers for all of the frame bolts to match the recess in the chrome trim. I used washers for the fitting. Not sure if I will just paint it black or match the lower bike color.

Specifics
Side rails: 1/8" Steel
Top Plate: 1/8" Aluminum
Support angle: 1"x1"x 1/8"
Weight: 7.4 lbs. (calculated)
Time: About 6 hours including putting the bike back together.
Rigidity: I literally sat on the rack with no discernible movement other than the shocks compressing. This was never really a worry as my chief concern was horizontal movement of which there was none as I applied what I guessed to be about 50 lbs. of side force to the end of the rack.

So that's it. I have a rack that lets me keep the grab rails and provides a lower mounting point for the trunk.

Nice work. Looks good. Nice to have access to the cad for turning out precision stuff. Can't wait to see the finished product with the trunk attached. Keep us posted.

I'd trade the CAD access for welding and machining access any day.

Stan,
Would you be willing to share your CAD file?

Well I got some time to install the trunk. No time and it's too hot to paint it so it's off the Crescent City with a black trunk. If black is really the fastest color I guess this makes me half fast. ;)

I installed the stock backrest off of the sissy bar. There is now an additional inch of room for the passenger. A good thing based on comments from the passenger.

I did a quick Photoshop on a solid red or two tone for the trunk. Without question it will be two tone.

And for those who care. Bracket weighs 7.4 lbs., Trunk & rack 18 lbs.

More pics in Sept. after it's painted.

Nice job Stan looks really good. The black matches your seat.

[jestephens]

That does look good!!

Way to go. Can't wait to see it painted

I hope he's ok. Or maybe it's old news and he's healed up and sitting on a new scoot already?
