I was in the maintenance shop & saw this happen.
2 men were working to change a 3/4 copper air line. The guy on the floor was BSing with the guy on the ladder & I was about 15 feet away using a vise for I don't remember what. I look over just as there is a big BANG. The floor guy goes for his...
Next time coolant stops. While the job is running tap in areas around electrical connection boxes/points & Valve bodies. It may help isolate the cause.
Where I used to work we needed to keep all of the flight simulation computers on line during power outages.
Our power utility ran a second power feed to the building from a different substation. Each power feed entered a quarter cycle switch with the output feeding our computer loads. All of...
Given that I have not fabricated any hydraulic cylinders.
Redesign of the piston may be the best way to get around this issue as Mr.Atoz said.
trevj asked about the location of the ports in an area where welding will cause distortion.
I would ask if the ports could be moved to the cylinder...
For what is worth. On a 8" bench grinder with 3M non woven wheels in the aircraft hanger. I was just going to take the burr off a piece of 1/8" 1018 flat stock. I noticed sparkles on the bench. As it turns out there was a light coating of aluminum & iron dust on the bench that was burning. I...
I am not sure if any of this stuff is still using "Battery Backup RAM" (BB-RAM) chips but if their battery fails the chips will need to be replaced with new chips. You may be able to reload the the old BB-RAM but if the machine is turned off the data will need to be reloaded every time.
? Rig compressed air to the bottom of the jacobs chuck to blow out the chips & cool the drill. Adjust your feed so you do not get long chips & by all means ware face protection. With cobalt drills i would try 2600 rpm & see how it goes. How many of these have to be drilled out?
Good luck

Parabolic drills might work for this type of a job. However I have never used a parabolic drill on UHMW. My jobs for them was for 30 to 40 diameters deep in 60-61 aluminum.
I redid my fathers 1940s house in the late 1960s. The only lead I found was was that used to caulk the cast iron soil pipe. A plumber loaned me his lead pot, propane tank & gave my 40 pounds of 1 inch lead pipe he removed from South Saint Paul Minnesota buildings in years gone past. He also...
If you are thinking of using a hardware store FLYCUTTER be aware. MANY of these things will not stay set. No matter how well you tighten the set screw securing the cross arm, vibration will work things loose.
Of all the tools in any shop the inexpensive FLYCUTTER may be the most dangerious!
Unless I could run the machine, I might hope it to be a diamond in the rough but expect it to be electricaly busted.
The less I know about something I have never run the more carefull I must be.
