Re: 6' rotary cutter blade broke off

The blades counter-rotate, it's all shaft drive so they stay in sync. The drive shaft speed is 550 max, I run it a little under that. There are 3 gear boxes and I did calculate the final ratio when I first got the thing but I don't remember what the result was. It's a UK made agriculture thing they...

Re: 6' rotary cutter blade broke off

Do they rotate in the same direction? How fast do you turn it?

Re: 6' rotary cutter blade broke off

It separated at the point where it swivels. The weakest point as there is maybe 1/2" of material on either side when new. The blade weighed about 12 pounds so yes Harold, it shook a bunch.. :) I found both parts and it looks to have been weakened over time and there is evidence of fresh break at abo...

Re: 6' rotary cutter blade broke off

I backed it into the shop and will put it on the car lift to get to top and bottom. At first look at the attaching bolts and nuts a saw that they were welded so as to not come loose I suspect. Oxyacetylene and/or plasma cutter may be in order.

6' rotary cutter blade broke off

I was using my 6' rotary cutter in some very light stuff in the pasture and one of the blades broke off. Made a mess out of the side of the brush hog as it departed. It broke where the bolt goes through (the thinnest part). Man did it make a noise and throw the unit out of balance. I do not have to ...

Tour of the 747 assembly building

Had a great tour of the Boeing 747 main assembly building in Everett Washington today. Largest building footprint in the world.

It is amazing to see two 747's and four other full size aircraft nearly completed in one building. My legs are tired.

Re: Lathe setup device

I made a device that uses a light to indicate on center. I sandwiched a very thin piece of sheet metal between two plastic inserts and stacked them on a steel column with a bolt to hold the whole stack together. I then ran a wire from the base of the device to the thin piece of metal with a 9v batte...

Re: Chainsaw Sharpening: Files v. Gadgets

I will touch mine up once with a file and then the next time send it in to the shop to get it done correctly and back and forth. If not sharpened correctly, the chain can cut unevenly and may cause damage to the bar and then it will never cut straight.

Re: Newbie - Buying first metal lathe

I have an old 12x36 Enco. It cost me $400 to have a machine to learn on. It most likely will not be the last machine I buy and I have learned a tremendous amount by using it. It makes what I need for around the shop and farm and basically nothing I make leaves my 75 acres. As mentioned above, taking...

Re: Shared air and electric line

Below is a calculator. I personally would shoot for a 3% voltage drop or less. For a test, run Copper 10 AWG wire and see the results then try 12 AWG. Although 12 AWG will handle 20 amps, it has a cost for trying to push it through the wire and that is more voltage drop than you may wish. https://ww...
