wishbone lightening holes?

[kelseydum]

I finally about got my wishbone done. I had a question about the tubing I need for the lightening holes. Is there a specific size (wall thickness) I need for these or can I just get some tubing with like a 1/16" wall? I had enough around the shop to do the first hole in each of them but wanted to ask this before I do the others. I drilled a 1 1/4" hole with the tubing in makes it about 1 1/8". Do I have enough room to drill one more... is one more needed... do they look okay?

Also the brackets for the spring pivot I got from speedway. Are these going to need some gusseting? The plate is about 1/4" thick.

Here are some pics...

... couple more. I drilled four holes in each end to plug weld the bolts in there. Do I need more plug welds than that? I'm still going to do some more welding on the ends.

Look good! I always try to use no less than the thickness the arm,frame,ect is ! make your tubes the thickness of your arm short so that it sits half way through and weld it so that when you clean it up with a grinder you are not grinding the weld away! Keep up the good work and show us some pics when complete!

Thanks, did I mention my father-in-laws 60 year old drill press crapped out on me after the first hole in each and I did the rest by hand... my arms are sore.

Even though they look beefy, are those alum heim joints on the end of your wishbones? Just a suggestion, do not use alum. How are the plates on the bottom of the wishbones going to be used? If they are going to carry a lateral load, a couple of gussets would be right.

The heims are not aluminum. The plates will be hanging off of the bottom. This is where my front leaf spring will mount.

Be sure to use a jamnut on the heim so it swivels on the ball and not on the threads.

Thanks amos moses, I've got some there just not on there yet.

Here's some more pics if any one is interested how they are coming along. I'm still going to add a gusset or two on the spring mounts (and finish welding them) just for my own peace of mind.

I think they'll look good when they are painted black.

you know those are not made to carry the chassis weight right ?????? there made to take loades from front to rear only..... and you should have welded a threaded bung in the end for you heim joint not a bolt..... as the heat from welding has taken out the temper of the bolt. and cutting holes in the bones was done for racing purposes only not intended for street use . the tube in the bones is thin enough. better be careful and not get hurt. this is very critical now also this is just a old man speaking his opinion for yrs or doing this stuff.
