1970 Murray Eliminator? restomod project.

Day on of my $20 purchase.

The wheels were too scrapped out to salvage, a brake caliper and handle were missing, so it was time to source some new parts out of my pile.

A 26 inch donor bike provided all of the brake hardware and it's Sturmey-Archer 3 speed planetary rear hub.

20 inch allow wheels were sourced for the project, but the spoke count of the original hub didn't match the new rear rim, so the 26 inch bike gave up hers for the build.

That in turn required the disassembly of three more wheels to play mix and match with the proper spoke length for my re-lace.

A vintage style cheater slick was sourced for the rear of it, and the front got treated to a super skinny tire for a three wheeled recumbent bike to stay with the dragbike theme.

The fenders were sourced from a bike that got squashed by a car.

?

Since they were off a new bike, I did a faux patina treatment on them.

?

They were sanded to bare metal then painted with a very similar color as what little paint was still left on the bike then soaked in a solution of white vinegar, table salt and hydrogen peroxide until the rusting began and killed most of the new paint.

?

The original seat was about as hard as glass, so I soaked it in heavy coats of tire shine compound for about a month to soften her back up.

That actually worked perfectly and allowed me to retain the patina on it.

?

Basically, every bearing got replaced, new brake shoes and stainless cables were added to it and the end result was a bicycle that retained her well earned look but was all new where it counted, hence the restomod designation.

This is called a mixer valve.

It's function is to mix natural gas with the air intake charge to fuel the engine.

The replacement valve assembly was made out of 12l-14 free machining steel with a 6061 T6 poppet.

I figured that the aluminum was an ok choice because technically this engine only runs about 40 hours a year now.

The valve stem bore is being opened up on a Bridgeport vertical to accept the larger diameter replacement I made.

The 80+ years it was in active service finally wore it completely out.

The pintle in the original photo trashed the bore in the housing until the poppet broke off of it and shut the engine down.

It's really cool to be an active member in our Association and to have the skills required to keep as much of it alive as possible.

The flywheels on this puppy are about 7 feet in diameter.

We use a Farmall M tractor to fire it up because the air starter got away from it decades ago.

Depends on your distance from the equator.? Changes in latitude, changes in attitude.

Try this for time and earth 360°

& try this for time at different Latitudes

?

One hour is 1020 miles

?

how about one minute

At 0° = 17 miles in minute

at 35° = 14 miles in minute

at 65° = 7.2 miles in minute

?

.

how about one second

?

At 0° = 0.28 miles in second

at 35° = 0.23 miles in second

at 65° = 0.12 miles in second.

?

35° 0.8192

65° 0.4226

?

If your time is off 5 minute 35° you are 70 miles off

The mini lathe can have a full length tapper attachment.? It work like tapper attachment from 1900.?

I have talk to you pass about your name? Hi again Dave?
