The Home Machinist!

This is a common defect, and I first came across this on a 12x40 belt drive lathe in 1980. It was the first new lathe I had ever owned and I was proud of it. After using it a while I found out the tailstock and headstock were both pointing up. The cross slide on the tailstock had been machined with ...

True enough. But after opening my worm drive and finding it lubricated with chinese Yak fat, and the gear faces dry, I thought gear oil would be a good thing. There are gear lubes out there that work and are safe on brass. I want something a bit thicker than motor oil for my saw.

From ShopFloorTalk forum: From an oil chemist I am betting that the gear oil you used is a GL-4 or GL-5 gear oil, those are EP gear oils using a sulfur phosphorus EP agent that will eat up than nice bronze bull gear in your worm gear set. The S-P EP additive is not compatible with any copper alloys....

I cut a 4 in 1/4" and a 3.5" in 1" plate( with 2 kerf holes drilled. They are a real nice shop machine.
Most use is for 1 to 1.5" twist drill work though

Got the identical drill press with the Nider brand name. It's an NI64
It is a great drill press.
It was 3 phase so I equipped it with a little VFD and I can dial it down even slower when doing a big hole saw job, etc.

I am a beginner at TIG and have been wondering about this. More efficient use of gas would be the result and a better weld, I hope. I have learned the hard way that most American branded stuff is made in China but the price is made in USA. Are these gas lenses standard sized and can new Pyrex or cer...

There is a tractor puller in my area with two Ford 427 engines coupled together with a 1" pipe nipple threaded into a plate attached on each engine.

I had a setup almost exactly as you describe it, with a 3 ft cast iron flywheel and double row ball bearing on the 3" shaft, and as I process scrap it was given to me by the owner who had had the splitter knife come off and hit his chest when he was splitting. My dad had used these and told me ...

If it was mine, I would use NiRod and build it up with nickel. Or use NiRod to weld in a chunk of steel. I do a fair amount of cast welding and sometimes on transmission mount pads for tractor fork FEL frames the missing chunk is so big I replace it with steel. When doing frozen engines, and the are...

Yes, I have to go to the 4th when doing a press fit bearing holder, and I wish I had a grinding setup, but the paydirt isn't in it. The majority of my work is horrifying stuff. Shafts made by John Deere to fit bearings private labeled to JD with 15 thou clearance, and the owner wonders why the beari...

You are right, chasing the elusive 4th decimal place is foolish, but people do it. For most home applications 1 thou is great. I often think of when I used to do driveshafts and busted a gut to get under 10 thou. Then I read the specs and factory runout is 25 thou....yep, for something turning 2500-...

Ray, if you use the 3 jaw chuck, you will be within 2-3 thou and the next part will be off maybe 2 thou, a scroll chuck is all over the map, even new.
A collet chuck is dead accurate to the spindle of the lathe. Every single time.
