Re: LED Lights in a Workshop

Makes sense as the old fixtures are so much more substantial. They are likely tubed/piped together as a framework. Much of my old stuff has those reflector hoods. I had case of the thinner tubes and when they don't work, the old ballast is the culprit and I have some of both. Another thing is having...

Re: Bridgeport J head spindle oiler question

The delivery of the oil is important. It needs to go exactly to the open bearings. I have seen there are small copper tubes. Only then does a wick as a pipe cleaner make sense. I believe many of the copper tubes fell off or lost during time. I still think a felt filter in the cup is good. There are ...

Re: Bearing Fits?

This has been good information. I bought some precision bearings for a mill spindle and the code needed some investigation. Well heck I bought them anyway. These are super tight and could deform a hollow spindle.

Re: Category: Who cares?

I noticed HF has yet another sale going on thru this weekend. 20% off coupon means their newer small MIG welder is $87.00 This is an updated 125A unit and the reviews are good. I have a MIG but it is a heavy unit 100 miles away now.

Re: Category: Who cares?

Can't be perfecto at that price. Notice all the small trailers have disappeared ? Hey they weren't promising a rose garden or overloading while driving highway speeds. So now they are gone.

Veiled praise.. No. Worry. When they get it all right, there is too much more up their sleeve. They. Them. CHINA baby, CHINA! From tooth brushes to toilet paper and in between.

Re: I want to make new lathe feed dials

I'm really a proponent of how things are done. We are talking .001+ dials now. Sorry but I wouldn't trust my used or even new stock for this.

Re: Compact 5 change gears

Yes it is. Pondering how to keep the variable power feed and the gear quadrant. Since "H" is a spacer, in many cases a smaller gear was used as a spacer. It could be a cog for the belt at some point but a longer belt with rollers would be too flexible for accurate feed. Sorry. Just thinking..

Re: Compact 5 change gears

I've been trying to figure this Compact 5 chart out. "W" is spindle and "H" is so important that they would have had to make the chart wider. I think "H" is toward the Headstock. So they abbreviated the gear number by the vertical " I " mark to the next gear. In this case it would be 20T. maybe. The...

Re: Rebuilding(?) a worn out lathe.

Please. You are fine. There are flat mechanical issues with so much, we border on certain people knowing more about one or the other. Fine preparation and great paint is one facet. There are jewels which need the "holdings" to be correct. Mr. H will set us straight on the logic when everyone is wand...
