OK, he is saying "lead screw OR feed rod". (OP: Feed rod is not used for threading. ) If both are causing issues, either both are bent, or the problem is further upstream in the gearing. Here's a real rough test to see if they are bent - run carriage all the way to one end or the other. stack up "st...

This chump understands heat transfer calculations. It depends on temperature *difference*, delta T. Deliberately raising the temperature of a heat sink or placing it in a warmer location is not sound practice. Rig up a remote control, the VFD for my mill lives in a wash-down box up on the wall. The ...

Heat would be another reason not to mount it to a motor. The inverter will likely overheat.

You don't need to clutter your desk with an external drive. Most PC's will let you install extra internal drives. Sorry, but that is bad advice. Agreed. In my business, backups are generated each day to high-capacity magnetic tape, with a separate tape used for each day of the week. My office used ...

I was kind of surprised to find anything there from Havir.

There's a kind of a part list at the end of the operators manual available over at Vintage Machinery. Not a nice exploded isometric parts diagram, but better than nothing I suppose.

Used 'em a ton back in architecture school and in building cardstock and museum board models in the office. That sort of stuff has gone the way of the T square in our business. We can make a 3D computer model that is much more realistic in less time, and it holds the bones of our design when we migr...

I was told by one of the John W. Brown crew that gear making required for turbines was in short supply and needed for warships, therefore piston engines. I spent quite a bit of time in the engine room on a cruise. It is amazing how quiet that monster is even at full throttle.

I had a cancer scare - yup, I had it, now I don't. Whew. Got a great new scar out of the deal though! I put a value on each of my machines (damn low), where to post them, and people around town that could help. I made sure that "lathe" mentioned the toolholders and accessories in the cabinets that w...

After you've fought with lugnuts on the passenger side of an older MOPAR vehicle, you remember. left hand thread on the R/H side of the vehicle. Same with Willys.

I haven't dealt with many suppliers, but I did place an order with Steve Alley recently, who now has Allen Models. He must gotten the customer service module as well. Wrote to me to apologize for not shipping the next day as he was sick, gave me a day he would ship, and beat that estimate.

Are you saying you can't melt the welding rod with the torch you have?
Also, have you ever seen a butane lighter explode? It's pretty dramatic. You might want to get that away from the work area.
