Re: titan machinery milling machine defect

I suspect the head may have been out of tram in Y and with no adjustments for that condition someone rtied to fix it with a grinder. If you bought this machine from a dealer you should definitely return it.

Re: holesaw on a lathe

The plates are larger than your chuck. How are you holding them on the lathe?
Running that size hole saw on the lathe was a wise choice. Most drill presses run way to fast for large hole saws.

Re: essential tools for milling

Sooner or later you will need an angle plate. An edge finder and wiggler are near necessities.
Consider screw machine length drills instead of jobbers. They are really handy when you have limited headroom.

Re: Clockwise Anti - Clockwise To Undo Machine Spindle Nuts

The hand of the thread may have been chosen so the nut will not work loose when the spindle is operating. I figure both heads turn in the same direction. Expect one to have a RH nut and the other to have LH. Try turning the nut in the direction the spindle turns.

Re: Can you help identify these items?

There were lathes larger than watchmakers lathes that used that style tool slide. One name that comes to mind id Derbyshire. I know Pratt &Whitney made a lathe that used that style tool slide. I used one in the school shop in the 50s. As I remember it had about a 10" swing.

Re: The Cheap Tool guy got me...

Many sellers state which thread is used. Don't buy from those who don't.

Re: Self Tapping Screws Don't Self Tap

There are various types of self tappers. Some cut a thread. Some form a thread. Anf then there are sheet metal screws. A photo of the screw would help.

Re: Vice sizes

FYI, Stefan Gotteswinter, a prolific author of You Tube videos uses the screwless vise on his mill. I believe he has a Rong Fu RF45 mill. By profession he is a toolmaker so he should know what he is doing. I should add that I don't think I ever saw him taking heavy cuts with large end mills.

Re: I bought a Lathe

Too many of the standard parts for the lathe are missing to make it practical to restore. Remove the carriages, add a tailstock, and make it a wood lathe.

Re: Teeter Totter finger for dial indicator

There were 3 eBay links posted. The first two were attachments that fit the back plunger indicator only.

Re: endmills in collets, and using in horizontal mill

Back to the question about endmills walking out of the collet: They can. Solve the problem by switching to end mill holders. I am guessing your vertical head uses 2MT collets. 2MT end mill holders are readily available.

Re: Odd runout on mini lathe

I have owned several lathes over the years. None of the lathes had what I consider a highly finished bore on the back end of the spindle. I would not trust the bore to be true to the OD. Your runout issue may be merely the result of the bore not being ground after machining.
