My first post, hoping for any guidance from this terrific group on my 1980 Jubilee restoration challenge. Please excuse any breach in etiquette if I've missed something.
On our first trip last fall
noticed it was sitting a little low. A lot of bouncing but no tire rubbing. Visible frame rust added concern and distortions in the shell need investigation. With only 2 inches clearance above the 13” tires
and the wheel sitting noticeably forward in the opening, so I'll be starting at the bottom and then work up from there.
Just removed the frame and the cantilever from the axle
rearward drops more than 1” out of parallel with the front frame. Both fiberglass wheel wells have cracks in the front at the point where where the top frame tube lap joint ends.
Planning to replace the torsion axle
that is stuck up at about 18 degrees and maybe add a tapered steel gusset under the rear frame running back from the axle
to re-support the rear and some extra crossmembers to stiffen the floor in spots.
Included are some photos and some initial questions:
1. Does the axle welded mounting look original? Were brakes
an option in 1980? The 10” brake drums are Dexter. Would they have fit on the original spindles?
2. Considering installing a #10 Torflex 3500 lb with 0 degree angle. Does that sound correct but I may later switch to 14” rims so would 10 degree down be too high? Also not too stiff.
3. Is the rear frame sag unusual or a common problem?
4. Does the crack in the wheel well look serious or more cosmetic? Since it’s on both sides equally, I think it’s the result of concentrated forces from the frame flexing, so I hope stiffening the frame will help.
Well, that’s a start for now. Reading about others experiences can be helpful so I’m happy to contribute for other Jubilee owners with similar issues.
