Paul shared this update on some custom heat shields for Knardly Rolls.

Paul writes, “The exhaust manifold is closer to the steering linkage than I’d originally intended but there isn’t any easy way to increase the distance between these two systems so I decided the best solution to this problem was to make some stainless steel heat shields that would bolt to the fender and fit between the exhaust manifold and the steering linkage.  

First I quickly made a test shield from some leftover poster board so I could check how this paper part would fit before I cut any stainless sheet.  Once I had the shape of the heat shield figured out I made a test piece from thin gauge aluminum.”

“First I made a test heat shield from poster board to check for the correct shape.  Once I was satisfied with the shape of the heat shield I made one from thin aluminum to double check any clearance issues.  After the aluminum shield was modified I made a third shield from thin stainless sheet but I saw a need to fit the fourth and final heat shield a little closer to the manifold and also use a thicker gauge of stainless to prevent unwanted flexing during use.  Once the fourth shield was fitted I drilled the attach holes and bolted the shield to the front fender.”

“Here’s the final heat shield temporarily attached to the front fender using Clecos so I could drill the fender and the heat shield at the same time.”

“As you can see, the double U joint between the lower end of the steering column and the first steering shaft is still exposed to heat from the exhaust manifold so another heat shield was necessary.  This smaller heat shield will be attached to the steering column by adel clamps so it’s easily removed for maintenance.  The two adel clamps are bolted to the column with enough threads exposed on the fasteners to attach the aft end of the second heat shield while the forward end of the second shield attaches to the aft end of the first heat shield where the two empty holes can be seen.  If you read that last sentence fast it sounds like a square dance call.”

“Here’s the paper pattern and the finished stainless steel second heat shield ready for installation.”

“With the second heat shield installed I think most of the exhaust manifold heat will be deflected away from the steering linkage thus preventing damage to the U joints and shafts.”

Today’s the last day of the year, so let’s go out in style with Alaska Paul’s placard progress. Paul understands that his one-of-a-kind electrically and mechanically designed jeep will require information assistance just in case any of us lesser mortals attempt to drive it. So, he spend some time over the holidays playing with placards.

Paul writes, “It’s been a while, so I figured I’d send some Willys progress photos your way. This photo is of the fuel valves between the front seats with an engraved placard sitting on the metal cover. A local sign shop (Alaska Laminated Signs) made up some test placards so I could see how different colors would look with the stainless, gray and blue interior of the Willys.  While this placard has all the necessary information and the correct shape to fit the metal cover plate I wasn’t too happy with the black background and the white lettering.  I wanted something with more visual appeal so Dave (the sign shop owner) duplicated this placard using a brushed aluminum outer layer over a black base.(see next pic)”

“This aluminum/black combination looks good by itself but I didn’t feel it looked good when it was placed next to the stainless steel parts so Dave made a third placard using a dark blue upper layer and a white base (see next pic).”

“Now this is what I was looking for.  While the blue on the placard isn’t a perfect match to the blue on the seats they’re close enough so they look good together and the contrast between the white letters and the blue background makes it bright and easy to see.  Now that we had a color selected I gave Dave my metal full size patterns for the five placards needed for the little Willys and he began the cutting and engraving process.”

“Here’s the finished product. From left to right we have the overhead switch placard, the circuit breaker placard and below that is the fuel tank selector placard and the final two placards are for the 12 Bosch relays (two rows of six each) in the electrical bay just aft of the passenger seat.

The placards fit perfectly which made installing them a fast and simple task.”

“The electrical bay with the placards installed.  It’s hard to see but just below the row of number 1 thru 6 relays is another row of 7 thru 12 relays but not all are in use right now.  I wired in some extra relays and extra circuit breakers incase someone wanted to install additional electrical equipment in the future.” Continue reading →
