It's a great idea Steve, if you have the resouces to do it, I don't and that would cost a fortune to have someone else to do it for me.Quote:

Baz.
A length of 45mm solid or 65SHS6, a couple of 10 or 12mm flanges drilled on the press or lasered/plasma table, a few tabs for dampers and calipers and then 15minutes with a proper MIG. Any old joe engineering shop would do this if you have some drawings for reasonable money.
The rest of the components become bolt on bolt off.
The grief you seem to be going through it would have to be an option?

They list 10" Commodore pattern for slimline/Ford bearings so only need the 14mm studs if slimline bearings are OK. They list 14mm studs for a LC hub.Quote:

I think it is still a work in progress.
Talk soon.
I have 9 x 2" offroad mechanical braked hubs at home that Melbourne Trailers did for me way back when I first went to D2 alloys in 05 on the camper, if D2/P38 alloys fit over the bearing housing, I can't see why D3 alloys won't, my hubs have Ford bearings.Quote:

Baz.
Same bearings fit so even if the boss is slightly larger it could be machined.
The smaller outer slimline (or LM) bearing has an OD of 45.2 mm so not possible to have a 40 mm boss.Quote:

They produce a 5x120 pcd parallel hub with 2 slimline inner bearings with the boss 76 mm at the outer end and a 105 mm (IIRC) register/hub-centering ring which they believed fitted the Discos until I explained why not. They agreed that the register could be reduced to 79 mm because they do that for Ford rims that have an 80 mm hole but they would not machine the boss to 72.6 mm.
Apologies, I am possibly not being as clear as I need to be. I am sensing my comments have confused some and have resulted in some confusion between the diameter and the length of the boss.
Summary..
The D3 alloy rim has a bore of ~72mm however at the front of the rim and at ~35mm from the inside surface the bore narrows creating an inner lip for the hub cap to clip into. This lip is less than 60mm in diameter.
The standard hubs have a boss diameter of ~60mm and a length of ~40mm. This results in the hub hitting the cap lip with the boss.
The objective is to interchange rims from vehicle to trailer so boring the rims is not the preferred option.
It is possible that some hubs with brakes space the rim further from the hub but I have not found a supplier that can show me so I can measure, but that's more about my inexperience. Hence this thread was started.
Ah yes, that explains the figures. Baz's X5 rims will have no problem as the cap hole diameter is about 67 mm.
So you have tried to fit the alloy to the hub, I'm assuming the boss is the bearing housing and where your refering to is where the bearing cap fits over the end of the bearing housing, yes??Quote:
