able to take off the full 1/8" in one pass, though. With skill and a sharp toolbit, you may do it in 2 passes, but 3 is more realistic. This is not a very big machine. Setting up for threading is a chore, because you have to manually change the gear wheels for the thread pitch. I don't use any of my 7xs for threading, because I'm lazy and have a 12x36 with a quick change LS gearbox on it, & use that one. If your work can be done in the limited space between the face of the chuck and the TS center, (8" on the 7x10), you'll be pleased with this lathe. However, the 7x"12" has 4" more room, and is thus a great deal more useful, if you ever have a need to turn longer stuff. Not that much difference in price. This version is 4" longer than the 7x10 and weighs abut 20# more. Portability is not a problem if you are fairly husky, though. I bought my 7x10 in the early 80s, and started using it in right-out-of-box condition, after wiping the preservative off the ways. I shortly found the gib on the top slide needed adjustment and did this, then the cross slide one needed the same thing, so I did that too. This sort of stuff will need to be done on any new machine. Later, I found the detents for the FNR lever for the LS were slightly mislocated and re-drilled them. I bought the four 7xs I have years ago, and the most I paid was $400 for that last one, a 7x12, which came with ALL the factory accessories then offered. The others were #300, or less. My 7x10 was $275 with free shipping on sale, I think. I bought it entirely out of curiosity, and got a very pleasant surprise on first trying it out. Even at today's price, it's a bargain, I believe, but the 7x"12" is a bigger one. My experience. Mert -----Original Message-----

Subject: [7x12minilathe] Looking at buying the 7" x 10" w/ Questions So I've decided on the HF 7" x 10" lathe. For the longest time I was leaning toward the Tiag Lathe. But my Grandfather left me his tools and most of them will work better with the HF. The Taig uses 1/4" tooling and the HF uses 5/16". He left me a bunch of 5/16" tool steel. Also all the drill chucks and centers he left me are all M-2 so they will fit the M-2 tailstock. But I have a few questions- 1. I want to turn a 1" diameter piece of steel to 5/8". Will the HF handle this? I've read that it slows down when turn steel. Are those people just tring to cut to much at once? 2. Once at 5/8" I need to thread it. Is the threading feature easy to use on the HF lathe? 3. I need to re-work some oil-lite bushings. The outer diameter of the bushings I buy is correct. But the inside needs to be bored from 1/2" to 5/8". Will the HF handle this within the accuracy needed for bushings? Would I be better of using a small boring bar or a 5/8" reamer (I happen to have one). The flange on the bushings also needs to be thinned but I'm sure that's easy enough. 4. I sometimes need to to take two slices from opposites sides of a round bar to be able to put a wrench on them. I've read that it's possible to chuck a end mill in the lathe and do slight milling. Do you feel this would be an option or is it wish full thinking? 5. I see a Prep Guide in the link section. Is this what's used to make all the initial adjustments when I first use it. From what I read I'll need to do a lot of tweeking to get it right. Any help is appreciated and thanks in advance, Tom ------------------------------------ Yahoo! Groups Links |
