Just like this blog, life is a hit and miss proposition. Unexpected challenges tend to present themselves at the most unexpected times. While there's never a good time for bad things to happen, there's also never a bad time for good things to happen. So we roll with it, or it rolls over us. Our paths are shaped by some events, and unaffected by others. The following is a typical case study.
The iconic nine foot tall America's Most Beautiful Roadster trophy stands on a platform of plaques honoring the select few who have earned the proclamation. The Great Pacific Northwest is represented (twice!) by Portland, Oregon machinist Lonnie Gilbertson. Accolades like this can change a person's life in profound ways. Thankfully, it didn't have much effect on Lonnie. He just kept building. (Photo courtesy of Street Rodder magazine)

When he isn't crafting award winning vintage tin, Lonnie is tearing it up - illustrated here at the front of the pack on a Northwest dirt track. Bonus: Most of the cars are street legal and drive to the races.
Lonnie's show and go '55 Chevy recently graced the cover of Street Rodder magazine. Life doesn't get much sweeter. Then, the unexpected happened...
Top secret spy photo of Gilbertson's latest (Code name: Hit and Miss Special), spotted at Marty Strode's legendary hot rod shop, hidden in the hills outside of Portland, Oregon.
The visual hit is intriguing, but the story behind the concept is a jaw dropper. Lonnie took a few minutes from his chores at Gilbertson Machine Shop for an exclusive SGE mini- interview.
Scotty Gosson Exposed: Okay, alright... What is THIS all about?
Lonnie Gilbertson: Well, I've always been interested in the Hit and Miss motors.
SGE: Uh, 'Hit and Miss', being slang for a single stroke engine?
LG: Yes. In stock trim, the motor fires, or 'hits', and then coasts, or 'misses', until it slows down enough to hit again. It's governed at 500 RPM, stock. It only has one rocker arm, on the exhaust valve. The intake valve has a light spring on it, and opens by suction.
SGE: Ah, gotcha. Please excuse my ignorance. Continue.
LG: When the opportunity to own one of these came up, I jumped on it. My first thought after I got it running was to build a scooter around it. I was surfing the web for ideas, when I came across a drawing by Matt Hurley of a Hit and Miss bellytank. I contacted him and told him I was going to build his artwork. I wanted him involved, as I couldn't take credit for the concept.
SGE: Good move. Not everyone gets credit for their work.
LG: At first, he didn't know who I was. I think he thought I was some kind of nut case.
SGE: Well...
LG: I told Matt that through my research, I found that bellytanks are designated as Lakesters, and that Lakesters with motors of 35 to 45 cubic inches run in Class J, and the record for that class is 167 MPH. My target is 50 MPH, and to achieve it, I plan to push it to 50, back off, and hope the car will maintain the speed.
SGE: This just keeps getting better. So, what kind of chassis and drivetrain will keep the little popper at peak efficiency?
LG: I fabricated the main chassis using the front axle and hubs from a Midget. Tires are 21" motorcycle, on custom wheel blanks from All American Wheel that I re-worked to fit the Midget hubs. The car will probably weigh about 1,000 pounds, as it has to be built by the rules to pass tech for 167 MPH. I chose to run a live rear axle - I can't afford any power loss going through a transmission or differential. I built the chain drive so I could change sprockets as needed, to reach my goal. The air-operated clutch assembly was designed by Jamie Fox, using (GM) Turbo 400 and C-6 (Ford) clutch drums that will be applied by air to parts taken from a Lenco trans.
SGE: I am so lovin' this! Can you tweak any more power out of that engine?
LG: Dick Elverud (famous Porsche race engine builder) will be building the Hit and Miss. At it's present configuration, it's 45 cubic inches, and makes one and a half horsepower at 500 RPM. Our hope is to keep the same cubic inches, increase the compression, and increase the engine speed to 1,000 to 1,500 RPM. I'm going to try to supercharge it by means of a squirrel-cage fan, hooked to an electric motor. We can't do anything mechanical that will take power away from the motor. Our hope is three to four and a half horsepower.
SGE: What was that about squirrels?
LG: Huh?
SGE: Oh, nothing... Lonnie, I would love to be involved in this project...
LG: I have to get back to work, Scotty. Just one last thing: When I started this, I thought people would laugh and think I was nuts. I'm overwhelmed with the interest in my project, and the acceptance by people of what I'm trying to do. I have an engineer friend who's intrigued, from an engineering standpoint, to see how fast we can go with such limited power. I know the amount of work involved - by a lot of people, including Marty Strode - to go 50 MPH at Bonneville seems dumb. But I feel it's all supposed to be about the fun.
SGE: Exactly! That's why I'd really like to -
LG: Thanks, Scotty. Gotta go. Take care!
That was the last I heard from Lonnie. But Marty Strode did click off a few more shots of the Hit and Miss Special while it was at his shop for tin and 'cage work...
Designated driver Jamie Fox makes a virtual test run while being fitted for rollcage, seating, steering and pedals. The grin indicates positive test results.
Marty Strode's shop is no hit and miss operation. Projects may roll in and out, but they all roll out a lot prettier than when they rolled in.
Marty continues the thrash on Jim Lindsay's Modified Roadster landspeed project. This week: Headers.

HIGH DRAMA AT CUSTOM METAL
Last week's blog spoke of the tensions that permeated Dr. Lockjaw's Custom Metal emporium when we clashed on the design parameters of the rear spring perch for my Model A project. We were both too busy to discuss it until this Sunday's session...
The culprit. A Toyota 4-cylinder powered '32 - '34 pickup, hauling a precious load. Tasty chop.
