So I'm at that part of the build that takes time & attention to detail...
Example 1). The gas tank is beautiful and ready to be installed...
I don't have any supports for the 'glass, rubber biscuits, etc. Back to WW!
Example 2). Wiring harness has arrived, fuel pump is installed... I don't have the fuel pump controller yet! Aaarrggghh!
When you are assembling larger components, it's easy to see progress. You can't miss a front beam, an exhaust system etc. Now I'm down to the fine hairs.
Motorcycles are like this too. the last 10% takes 90% of the effort/time.
At this point everything was progress, everything.

Update 10/17/22
It's time to wire up the buggy. All of the major components are in place. I got one of the 12 circuit kits from Speedway motors. It is "GM" based so ought to play nice with the similar steering column.
Step one was finishing up the fuel pump and associated components
Step 2 was fetching out the "FRONT" wires and getting them secured and routed to their appropriate locations
Step 3 Install the gas tank for (hopefully) the last time
Step 4 was installing conduits or raceways. My buggy doesn't have factory installed tubes, so I found some flexible conduit and straps at the local home improvement center and ran a couple of lengths under the side board and across the rear of the buggy
Then get the "REAR" circuits to the rear
Back to the front, dash, gauges, ignition etcetera, I decided to add a couple of terminal strips where I could break out multiple conductors on the same circuit... 12VDC+, 12 VDC-, switched 12+, Tach, etc. That way I won't need 5 wires landed on the ignition switch for example
Then I ran out of weekend _________________

Thanks Steve. Much appreciated.
Saturday was spent on the work bench with the dash, some gauges and an assortment of wire & connectors. (A special thanks to my "donors" )
I chose Autocraft gauges... Monster Tach, oil pressure and oil temp. An originalish speedo and universal ignition switch
I also wrapped up the motor end connections... but no pictures... dammit
Be safe everyone. Paul _________________

Back from KCMO over the weekend and managed to get the fuel system sorted, a battery, and... found the motor was tighter than a Nun's... well, you get the idea! It didn't want to turn over in the bellhousing. After contacting the builder, I was instructed to back off the motor and prove that the problem had cleared... and it did!. Re-clearance the bellhousing and viola! The motor turns! Man what a relief!
Remove plugs and unplug coil, crank until oil pressure shows up. Put plugs back in, connect coil and... one more time she fired right up for the first time! It's so exciting. for the first time in over 20 years (according to the tags) the buggy runs! It was so tempting to drive it down the street

Update 11/21/22:
It's starting to wind down, & I think I have everything to finish it up except time!
Over the weekend & between honeydos I managed to get the front lights mounted up & wired...
The headlights are from Summit, and I must admit, they are of pretty high quality. Higher than expected in today's market. _________________

So yesterday I made the first legit road trip complete with tags, license and insurance. Turns out that new tail lights don't come with bulbs! I only had one in the garage without stealing one from one of the other vehicles. I figured surely I wouldn't be the only guy out with a "burned out" tail light, so off we headed to the FLAPS for an 1157 and many looks.

Thanks guys. It's just a ball. Very entertaining.
On the maiden voyage I discovered that my steering was less than ideal. It just didn't feel right. Wouldn't you know the only part on the chassis I didn't recondition or replace, the steering box, needs some love now
Have you tried to buy a TRW box lately? It's like buying an 1 5/8" exhaust all over again... dammit.
From July of last year!
Would sure have been easy to do then, wouldn't it? _________________

Does it have lube in it? If it has some slack there is an adjustment to take it out.
How about the tie rod ends? Or is it more how it handles on the road. The car has a lot of rake, did you put castor shims behind the beam? With that rake you might need 2 sets of shims. _________________ We had the stone age, the bronze age, the industrial age and now we are in the age of mass deception and mind control for corporate profit.

What do you have for access with the body on? For the most part these old boxes can be adjusted to work. The failure point is if the roller binds and quits rolling or if the roller develops excess end play in its cage. If you can see in the oil/grease fitting holes you can determine if either is the case. By design the worm gear is cut so the steering is tight only in the middle of its travel, excess play when off center cannot be felt when the vehicle is in motion because the steering is trying to return to center.
I don't think the new TRW boxes are available. I compared my old box to one of the other new steering boxes and decided to adjust my old box. I looked in the oil hole and verified that the roller is turning and not moving back and forth in the cage. I also filled the box with the thickest oil I could find. I found the center of travel and put the input there. I loosed the roller adjustment a little and then set the worm end play to a smooth zero. I then tightened the roller to find that no play spot in the center of travel. It moves slightly off center as the worm bearing is adjusted. From there I tightened just a little more so there was about 90 degrees of input travel with zero play in the pitman arm.
The quickest fix that I would trust (in light of the quality reputation of the new boxes) would be a rebuilt original steering box. Airkewld is the only place I know of offering rebuilt original steering boxes. _________________

As EVFun said, you can easily adjust the steering box. I also strongly suggest that if you have not checked your alignment, both front and rear, do so. When off, the buggy can have a tendency to wander. Caster shims have helped my buggy to track straight. Also, check that you pitman arm is on tight. |

Yes Sir. It has lube in it. I even went to the trouble of drilling & tapping the lid for 1/8 NPT so I could add a zerk and a plug. Tie rod ends are brand new, and it has castor shims (2 ea.) behind the beam.
I tried to pay attention to how it responds this weekend, and made a few observations...
1). It's "tight" or difficult to turn even with the front end elevated off the ground
2). It's "loose" there is an excessive amount of slop in the steering wheel before the front wheels turn, on the ground or in the air. _________________

EVFun,
Thanks for the input. AirKeweld is definitely on my short list for fixes, but Santa didn't bring me one, so maybe next month! _________________
