Use a hi-amp stick welder and weld with 1/8 rod a seam all around fast . Let somebody turn the crank. Gear will fall off. Ola

Starting as helper and then progressing is a great way. And after 10 years start theoretical subjects on the trade he is in, with math and physics. Pretty soon he will advance into a very well paid foreman position. Stay away from the dead end "project manager/planning" jobs. Manual skills...

RPH explains the problem with inductive loads. Perfect. You may try bridging each relay contact with a 1µF 100 V high quality capacitor to reduce the arcing at switch off. Ola

Please use triangular cross brazing on large removed clips, before you detach them. KUDOS for your job. Will take some time! Ola

Fluke schematic and/or access to an undamaged Fluke of same kind will solve your Q. I guess 10 Ohms is correct and it does not look like it has been fried. What I do not understand AT ALL is why the part is broken. If it is part of a current circuit, FLUKE always use fuses to protect the...

Absolutely wonderful, Hewey! . Are those horses Clydesdale? My grandpa had a big farm with clay soil .Way down south in Sweden The only horses that could pull the machines were Clydesdale. Grandpa said they were more intelligent than all the farmhands! Ola

If you have some friend who is electrically and electronically gifted. Install a 60Hz full( ie two sep windings) transformer . Supply voltage primary and probably around 85 V secondary with a well filtered analog voltage DC regulator that fits the armature ( put all in //). Remove the...

Caterpillar shops ALL have a machine to make Orings from a large assortment of "rubber bands" All qualitiesof base material. And the glue joint is invisible Ola

" Use a relay" Yes Personally I prefer solid state relays. Ola

Max answer is fully correct. To calculate the voltage occuring across opening contacts in a DC circuit that has Inductance(L), resistance(R) and stray capacitances ( Cstray) is difficult even for a very well educated and mathematically competent person. I have made an amateurish scope pic (...

tlmartin Controlling a 12 VDC electric motor directly with a microswitch could be a problem. Starting the motor is not difficult, provided that it is not mechanically overloaded. IF you have access to an Ameter that stores the peak current ( ie a good Fluke and a 25 A /100 mV shunt) that...

In the 70s I read every number of "Classic Cars " a UK magazine. All about cars, technology and tools. They had an annual competition, " Best amateur repainted car" A 40 yo won one year. He had converted the living room to a spray booth and took in the car thru sliding doors to the garden...

My $ 0,02 Replace bearings with new that are sealed on both sides. Ending 2RS or 2Z. Buy only best quality like real SKF. They are lubricated for life even when fully loaded. And your motor spins 1750 RPM so "lifetime " will last very long. Ola

I was working in a big tire factory in the 60`s. Lots of pneumatic control equipment, running on arond 60 PSI absolutely clean air. All piping was copper tubes usually 8 mm OD. And we were finicky with install. Pipe came in 100 ft bundles appr 3 feet in dia. How to get a nice straight 20 feet...

Mr N. Swedish standard copper tubes come in 15 mm OD. ID is 13,0 mm Euro fuel injectors have a neck metal dia of 13,0 mm and a single O-ring seal with an OD of 13,4 mm Factory fuel rails have a seating dia of 13,20 mm. So I used a tool grinder machine to grind and polish each part to 13,2 (...

I overhauled the 6 cyl 2,8 l straight six on a friends MB 280 SL 1969. Around 220.000 km ( ie app 140kmiles) Also converted to Megasquirt and EDIS. Engine as new after boring , grinding crank and flywheel, new cyl head. All new fasteners. When tuning it suddenly stopped cranking. Starter spun...

KUDOS Fantastic work. Ola

The orange blob seems to me a taped cable sealing end. There appears , also, to be some insulating semiliquid, black, running out. The arcing explanation and semiconducting layer by rlitman above is absolutely correct The ONE most faultinducing MV and HV part is cable sealing ends of all...

Some input from lightning protection in outdoor HV switchgear ( ie > 145 kv up to 1250 kV AC and DC) . Power lines not included Stage 1 Umbrella wires ( steel wires dia 45 mm) around 6 meters above the highest HV part. At least 4 meters outside the switchgear foot print. Stage 2 Incoming HV...

Post # 7 above, and milk krate. I saw real pros on a gas station just north of Munich, around 1968. Needed a flat tire replaced. The gas station did everything out in the open. Including replacing a VW 1200 engine between the pumps. Jacked it up, put two old tires uder and in less than 5...
