Pelton wheel generator

20 some years ago I built a micro hydro generator to power saws and lights to build my house. One of the batteries failed about 10 years ago and the system has sat idle until I decided to check into running it again due to alleged federal incentives for green energy production.

The generator is a 10A, DC permanent magnet windmill unit. The Pelton wheel has a 2″ radius to aim the water jet at. The jet is just a 1/2″ NPT pipe plug with a 1/4″ hole drilled in it. During a drought I can go down as small as a 1/8″ diameter jet and it will still run. The penstock is about 600 feet long and has an 81 foot drop producing 35 PSI at the generator.

The inverter is a 5000 watt, 110V AC output, 24V DC input modified sine wave unit. The diversion load charge controller is below the Telco box. The charge controller diverts power when the 2 8D batteries are fully charged. You can’t just turn off the power because the wheel will overspeed. The 2 black cables in the upper right go down to the generator. Instead of using a generator disconnect to hook the inverter up to I put together a cable that takes the 2 110V inverter outputs and connects them to both legs of the 220V breaker box. You have to make sure the 200A main is off so you are not connected to the grid. This connection will power the 110V stuff in the house but not the 220V range or dryer. I installed a 110V well pump instead of a 220V unit. Electronic stuff does not like modified sine waves.

Bobsy Formula Vee Registry

I have created a registry for Bobsy Formula Vees. Jerry Mong began producing racing cars near the close of the 1950’s. Mong then developed a successful line of Formula Vee race cars during the mid-1960’s. The Bobsy Vanguard was built from 1964 to 1966 and the Vega was built from 1967 to 1968.The table represents the best information I have at this time.  New information is welcome as I continue to document the survivors.  Please feel free to contact me with any new information or questions.

More fluid drive info

I started researching an odd ball Nethercutt fluid drive for a Message Board member and came up with more washing machine fluid drives. Looks like they were used on Maytag, Amana and Simpson washing machines from the 1950s through the 1980s.

The top picture is a Simpson and the bottom is an Amana. These look a lot more like the engine mounted MK0 fluid drive than the Albion mounted MK1 fluid drives.

Obviously it is not the same casting but the size and fins appear to be very similar. I doubt there is a one way bearing also. These are also mounted as a driver the same as the MK0 instead of a driven like on the MK1s and MK2s. They are also available on Ebay at reasonable prices. One nice feature is that they are bolted together instead of welded together like all of my MK0 and MK1 fluid drives.

MK0 vs MK1 Handlebar Comparison

I believe the handlebars are from a BSA Bantam D1 and D3. They are still available new but the brazed on perches are a bit different on the new ones. MK0 on the right, MK1 on the left.

Both my MK1s and the MK0 have the same bars with English Doherty grips and twist throttle. I put a wider Aluminum bar on the Rust Bucket MK1 because I was riding it daily for awhile and the narrow BSA bars beat me up too much. I am trying to find a chrome plating shop. Eventually I want to get the Rust Bucket MK1 back to original.

More MK0/MK1 handlebar pics.

The kill switch is drilled and tapped on the left side of the MK0 bar and the same kill switch is clamped the right side of the MK1 bar.

Parking Brake

I know this is not original but I install parking brakes on all of our bikes due to the steep terrain we ride on. I first saw an improvised parking brake on a barn find MK4 auto bike about 15 years ago. I was able to identify it as an exhaust hanger o-ring from a Volvo P1800 2 seat sports car. The P1800 was built from 1961 to 1973 so at least the o-ring is period correct.

I store the o-ring on the left side since it falls off on the right side due to the throttle cable. The left side has the clutch lever. The brake lever is on the right.

I have been using these on our MK1s for years. The MK1s have the brake lever on the left. This really screws me up when I jump off the MK1 and onto the MK0.

I can store it on the left side with the brake lever on the MK1s.

I use a Yamahaha quad parking brake on our MK3 and MK4 bikes.

I retrofit the Yamahaha parking brake trinket to the original Magura brake lever on my MK8 bike.

U-joint installed

The u-joints were both worn out in my MK1s so this is the first functional example of an early u-joint I have come across. It has a grease fitting that is accessible through the fishmouth.

Here is the patent drawing showing the u-joint.

My collection of junk early u-joints. 2 came from my MK1s. Not sure how I got 2 more. None have provision for a grease fitting.
