Help Required (Geometry)

Wayne

Its 45 years since I did Geometry as a subject ...lol

Take a piece of card board and draw the 5 stud holes and the centre out with a texta pen. Then connect all 5 stud marks diagonally with a texta line to pinpont the centre. Drill holes in the card board to mark the stud positions and the centreposition and then transfer this on to the piece of metal you are welding to the wheel carrier(or whatever you are doing).

Hope this helps

Cheers

you can sonstruct this with a straight edge and compass, and a bit of maths

Wow,

That looks complicated to me.

I would just use a pair of dividers.
Inscribe a circle, then measure around it adjusting the divider points until you get 5 equal distances.

Or calculate the circumference of the circle (Pi x D) and draw a straight line with this length marked on it.
Get your dividers and step it out so it takes 6 steps to get to the end of the marked section. So that is 5 steps for the studs and 1 step to get you back to the 1st stud.

See how that goes.

Wayne,
Had the same problem, what I did was cut out the metal backing plate so that it would fit into and hard up against the rim where the studs go through and then mark the stud holes with a scribe.
Guess the centre as best you can and then drill the holes slightly bigger then the studs (about a mil).
Place the studs into the backing plate and tighten up onto a rim with some wheel nuts.
If your stud centres are too far out you will have to fix with a rat-tail file. Now weld the studs onto the backing plate,
PS I only used three of the studs when I was making my rear wheel carrier for the Troopy which makes the job a lot easier.
It also has a 20 litre plastic jerry can with a tap for washing hands and drinking water hanging off the wheel carrier as well. Been on for a couple of years and had no problems with at all.

sorry Wayne...bit late like a blister when the jobs done, but measure the distance between the studs on your wheels...the ones you want to drill into your carrier centre to centre, or edge to edge (thesame side tho) and set your compass to that...

Also an automatic feature in autocad Wayne.

Just specify no of holes/ dia and done in a second.

Step 1 Take kids to school

Step 2 Visist maths staff and ask teacher.

I usually ask the Mrs. stuff like this. Every now and then I see a plus side to marrying a smart woman.

I now step behind cover as the irate women who believe I have denegrated my wife respond.
