I've put a radius on using the method this guy does. 



It's slow and leaves some flat spots that are easily cleaned up, but it does work.

These are all great ideas that work great but here is another way that is much faster, if not as precise.

Paint on a coat of layout blue and scribe a radius with a protractor. Grind away the excess material with a belt sander using a 3M Cubitron II abrasive. This abrasive literally eats metal! Hacksawing away as much material as possible beforehand helps, too. Quick & easy.

I managed to use a couple of the suggestions, followed the video and then used the sander... came out alright... bearings about a .001 press
Here is how I plan to use it.... more structure required for the  attach points... but getting it close to the way it is planned.

Seems quiet here but I have been busy making parts for the Watts Link.  All the parts are made but some need to be welded together and others need welded in place.... but with any luck you will get the idea of where things are going with the pictures. 
Welding starts tomorrow...
I will be taking a couple of days off while the Docs rework my electrical system  undecided unfortunately my pump is running at 44-55 as long as I am up and moving... 41-38 if I am sitting down.... so Wednesday I get a timer installed... I have been resisting that but the doc says this is the fix to raise my energy level a little.
My buddy Ross is afraid I will end up like a 10 year old on a sugar high since I have always run slow...  rolleyes

That is what mine was running at and you know where I ended up.  I do have a lot more energy now so glad I got it installed.  It is a Boston Scientific Model K173.  I was worried about welding but have had no problems with the TIG or MIG.  Call me if you need any more info.

Been following all your good work on the lakester, keep it up  cheers

After throwing all the front end stuff together... I thought I should also add the other large chunks that live in that area... 15+ lbs of Halon.  I knew everything would be close, it always was before... and it still is, but now I have the front axle upper limit that is controlled several ways.  So with the shocks disconnected, because they will stop upward movement with the bump rubbers before the mechanical stop can be reached.
The axle is as high as it will go....

Here is where it is at normal ride height and then at the bottom in full droop. 

Of course while I was moving full stroke I checked how the Watts was doing... from full droop to full bump I could not find a measurable movement... of course we are talking about a little over 2 inches.

The one thing I found out is when they installed the new ECU, the wiring is a little fragile at first, so for a few days they want my left arm in a sling.... and they suggested that I might want to wear that sling anytime I am in the shop to prevent inadvertent motion with that arm.  Since there is very little pain associated with the arm movement they were right to suggest that. 
Working with one arm in a sling is tough but doable.  undecided

Full droop needs stops... So here they are... not welded in yet, Tig needs 2 hands... that may be possible after I see the Doc on the 5th.  They want limited arm movement for a month while the wiring scars in.

Congrats on getting through the rewire procedure.  I'll bet there was also something said about how much you should lift for a while.  I know it is hard for you, but take it easy and don't pull those leads out  wink,

It is hard to not do when you have energy to do....  undecided
Yep no lifting anything heavier than my di--.... so the 19 inch 1 x 1.5 tubes to support the bumpers was within my limit  rolleyes OK I used the other arm...  grin

Ran the lathe a little today making weld in stubs to put in the end of the tubes aft of the engine bay for the rear of the car tubes.

Still noodling the rear suspension... I still think I can improve on the old one, but we will see

When I set the lengths on the 4 bar and the Watts I determined I needed some way to hold the links while I tightened the jam nuts.  I picked up a couple of dollars worth of large nuts at the yard.
I modified a bunch of the nuts on the lathe to weld to the links...

So I need to do a little welding... the Doc said I could, just can't push, pull or lift with the left arm... I decided to give it a try... Seemed to work, I don't think the nut will fall off  rolleyes

I was looking at doing that too, Rob, until I came across these on eBay.

https://www.ebay.com/itm/5-8-18-LH-HEX-WELD-IN-BUNG-FITS-120-WALL-TUBE-HEIM-JOINTS/371529806554?_trkparms=aid%3D222007%26algo%3DSIM.MBE%26ao%3D2%26asc%3D44040%26meid%3D9af6b5fceecc4373842978fe64da464c%26pid%3D100005%26rk%3D4%26rkt%3D12%26sd%3D132502879464%26itm%3D371529806554&_trksid=p2047675.c100005.m1851

BTW, if you need more rod ends for rear axle links, I found a guy on eBay selling NOS RX-AM-8T Aurora rod ends for $15 per.
