Re: Power for a hoist

I have found a local Geek office that repairs radios and TVs. I am going to make contact Monday and see if they will look at this simple drive board. They should have little parts for electronics on hand or at least know where to get what is blown out there as since Radio Crap is gone I have no sour...

Re: Tesla cars

As far as electric cars: i think they are on the horizon , but for the wrong reasons. It takes more energy to build the system that makes the short life batteries than can be exchanged in service, and worse as they slowly fail. I think the solution will appear out of the cross over of the fueled hyb...

Re: How to gate and runner a car frame?

Dave F is hinting at the approach i would use. 32 inch to run is along way for a melt to travel and is asking for problems. Cold shuts and sand washing will be the norm. I have had success with tilting the flask a bit to let the metal puddle and then rise like a tide through the casting. The metal w...

Re: Never enough time

Understood about the belt profiles. Lawn machines cheat in that they allow out of line conditions and actually depend on them to run with all the drifting of the mower deck. Pulley and belt wear allow a deeper bite into the reaches of the pulley until the belt flips over, and that roll does them in....

Re: Never enough time

The pulleys on these are built up spot welded sheet steel with a multipoint star drive punched out of the center. they are held to the shaft with a hefty washer based nut, but they will spin on impact and strip the star. The pulleys are cheap, but fail often with rough use. The spindles are a pain a...

Re: Small Diesel engines for motive power

Dealers choice, some things are better than others. A former relative had a pulling tractor that made crazy horsepower. On a good pull it would melt the tubes for the exhaust and blow hols through them right before it spit aluminum from the piston tops. Crazy power. Too much money for me and repeat ...

Re: MIG for Cast Iron + Small Welding Table

I am not a welder either. We used to tack the strip for pull through on the pickle line with 6013. Lap over and run a few inch beads and pull it through. We used 7014 all the time for general repair and pipe hand railings. Some called it a farmers rod. OK by me, it worked well and laid out nice. Mul...

Re: Never enough time

At Mantards I asked and bought 4 led bulbs that fit into a 4 foot fixture for fluorescent. They did not light. So much for employee knowledge. Now I dunno what to do with these bulbs. The Edison base LEDs are working famously and give good light as advertised. Now if they last better than the culry ...

Re: Thinking of using PVC pipe for air?

DO NOT USE PVC WHERE THERE IS OIL, OR SUN. Better to use a rubber line and wind it around the shop. When the pvc degrades it will blow at the least cause, and the shattered pieces are missiles that are unpleasant. Spend a dollar and avoid the rush.

Re: MIG for Cast Iron + Small Welding Table

By the by, is GTAW, SMAW, and all that the proper names of Stick, mig, tig and fuel gas welding??? I learned how to melt steel together before I could ride a bicycle. I was doing soft and silver solder with my trains at 9 yrs old. I built a wooden 8 foot John boat at age 14. I learned before I know ...

Re: MIG for Cast Iron + Small Welding Table

Broken is broken. Our mission is to make it work and live on. Castings are intended to be a reasonable answer for a difficult problem of shape and design size. Once when tearing down a steam traction engine a cross member fractured. Running across the frame rails it required strength and a repair wa...

Re: MIG for Cast Iron + Small Welding Table

Welding cast iron is a real crap shoot. It depends on the grade of cast and the carbon content, and if there is any silicon in the matrix. Results with various alloys and brasses are mixed from good to forgetaboutit. For most attempts I like a nickle iron rod with a bit of preheat, Post heat and slo...
