Re: Precision Toolmaker's Vises

I've got a pair that are a bit larger since they open to about 2 1/2" that I got from Enco years ago. Unfortunately when I bought mine the bed height's and most of the other dimensions were not matched even close to being the same. For the smaller one's like those and when used as a sub vise within ...

Re: New small mill

Emco maximat sized rear mounted mills were pretty well made even with there having a round column since they have that anti rotation key so you don't lose your spindle C/L when moving the head. But your lathe and mill got into Israel somehow so there has to be a way to import equipment.Bills more th...

Re: Lubrication For Lathe Headstock

Properly engineered lubrication products are a complex science. Luckily we only have to understand a bit of the logic and physical properties behind that engineering for the lubrication products we might be using. High detergent oils such as those used in automotive engines are designed to keep any ...

Re: Machinery Course Textbook Recommendation

Well along with whatever textbooks you come up with I'd also suggest the Machinery's Handbook CD. That way multiple copies can be printed off for the whole class depending on the chosen subject for that day or week. One of the most important lessons would be the world wide use of agreed to standards...

Re: Anouncement - Shaper CD

John Stevenson passed away a couple of years ago and I'm unsure if his son took over the small parts and information business John had for various items. About all I can suggest is doing a few different searches on U.K. Ebay to see if it's still available.

Re: Sakai ML-360 Lathe Carriage Handwheel not turning/coming off

Does your user manual show you have all the parts your supposed to in that area? That hand wheel threads onto the end of the lead screw right? If it does you thread the hand wheel onto that threaded end of the lead screw until it's almost but not quite touching the end of the bushing the lead screw ...

Re: trepanning, or how to bore a 4" hole on a lathe without boring a 4" hole

Yeah it is isn't it RSG, I was amazed the first time I watched some of those videos. Choprboy pretty much nailed it. In one of the videos it was mentioned the cored part was headed to the bottom of the North Sea so really high pressure off shore oil wells is another use. I expect there's not all tha...

Re: Fly Cutter Problems

Maybe a few combined issues from what I see Glenn. Not one of the better grades of steel that are known for producing easy to get good surface finishes since it looks like the surface is showing some tearing. 1018? And what you already know an obvious tram issue if your getting a step at each pass. ...

Re: 4 Jaw Scroll Chucks

Fwiw the problem may not totally be the chucks fault. I've got a pretty decent Emco made 4 jaw scroll chuck that's quite accurate. And even with cold roll square stock it will sometimes need a shim. While I've not read it specifically said about 4 jaw scroll chucks, I'm fairly sure there meant mostl...

Re: trepanning, or how to bore a 4" hole on a lathe without boring a 4" hole

Interesting video and I hadn't known the HP requirements were as high as they are for that operation. I'd watched a few of this guys videos so knew about large deep hole trepanning https://www.youtube.com/watch?v=-ZPvfoVTdqE&t=195s

Re: Sound Bend 9" lathe, MT-3 to ER-40?

Having to buy and use an ER 40 collet system on that length of material that still won't fit through the spindle would just be a way of providing the rotary drive to the part. The fastest, most repeatable and accurate method of doing that job would be to just center drill each end and turn the part ...
