The Home Machinist!

Always good to know your history, the screw cutting lathe originated in the 18th century

Calculating the gear train is the easy part. Coming up with a solution that physically fits on the banjo is the hard part. Ah, but nThreadsP gives you lots of options, it gives you all the possible options with your set of gears, it even allows you to choose to allow an acceptable error if you so w...

The harsh reality is that not everyone has need (nor desire) to master machining. For some folks, their machine tools are nothing more than a means to an end---they want to build a widget, and machine tools are required. They have no aspirations of becoming a machinist, and have little interest in ...

Go ER40 instead, it's far less limiting and contrary to the opinion of those who haven't used one you can turn square, hex, octagonal and tapered stock in ER40 collets

I question the need. I was trained on manual machines and have never used a DRO. Seems to me like a lot of money to spend with not such a great return, but then I have the utmost confidence in my ability. That didn't come fast, or easy. H I thought exactly this way until I used a DRO, in conjunctio...

NthreadP is a calculator which takes your driving gear size. lead screw pitch, your available change gear sizes and calculates the gear possible trains for the thread of your choice. http://www.lathes.co.uk/latheparts/page14.html I use it to cut metric and imperial threads on my change gear Myford S...

Iscar MGCH06 bar and the appropriate GIQR8 grooving cutter/insert good for holes down to 8mm on the lathe For cutting plastic and the forces involved you could make your own holder rather than buying the MGCH06 bar, you can buy individual GIQR8 grooving cutters for a few dollars. https://www.google....

Drill under size from the opposite side and punch it out.

I built a pulley driven high speed spindle (30,000rpm) from an ER11 collet chuck on a 10mm straight shank and ran it from the main 7000rpm spindle of my machine with a pulley and round polyurethane belt. Once you grasp the concept it's not difficult to design something to suit any machine.

Roughing cuts are to remove a large amount of material quickly before finishing, if they cause issues with flex or resonance it's either not appropriate for the job or alternate tooling/techniques are required. I make a Titanium part which reqires a 2" length of 1/4" material to be reduced to just o...

Put it back! It was a safety device to reduce the risks involved in using such a dangerous bit of equipment.

I have three Harbor Frate Lift tables, and they all have one problem, when you pump them up to a desired height, they slowly go back down.

What happens that makes them safe in the event of a major hydraulic failure?
