anyone here work with or have access to use auto cad? i need some custom spacers made up but need a drawing knocked up to see if its possible first?
 
I didn't notice this one til now (I'm a bit slow atm)

The good lady is a dab hand with autocad and what have u. If you send me a rough idea of what you are wanting she could knock something up
 
I need a spacer to go on my hubs, 3x130 pcd that's have holes so I can bolt up a 4 x 98mm pcd wheel?
 
Was a guess to see if it was possible to overlay the 2 different pcd's, not a renault pcd though
 
Not sure what your plan is with regards to tapping the holes – if you want threaded holes then you need to drill as below, then use the appropriate tap

M10 – 8.5 mm
M12 – 10.25 mm

The above is for standard pitch

Have you thought about the thickness of the spacer & offset of the alloys? In my little world, thread engagement should be a minimum of 1 x diameter (I think ASME allow 0.75 but I’m not so brave), although for this stuff I would probably go at least 2 x diameter so about 24 mm.

If you are not using threaded holes then holes for M10 bolts should be 11 mm to clear and M12 should be 14 mm.

Good post.

Also, you should not tap wheel bolt threads (or any stressed item IMO) into alloy, like a spacer. At the very least they need to be helicoiled, like brake caliper hangers for example. I wouldn't do it at all though, too much stress on that face to risk it with ally.
 
Tbh I just need to know if it's possible to overlay the 4x98pcd and the 3x130pcd without interference
 
lol thanks! if its possible then ill move one to getting measurements up to make them, banded steels are the easiest option for me at the mo
