Re: Looking at buying the 7" x 10" w/ Questions

 

1. Yes, no problem if you listen to the machine to figure out a reasonable depth of cut.

2. No different than on any other engine lathe; the change gears for threading have to be installed manually - higher end lathes have quick change gear boxes that don't require as much fiddling to change gears.

3. You'll want something other than the stock 3 jaw chuck to hold the bushings. The stock chuck doesn't usually hold things concentric; it's more a function of the chuck body not being too accurate than an inherent problem with self centering chucks. The easy fix is to machine a split sleeve that grips the OD of the bushings. As long as the sleeve is in the same position relative to the chuck as when it was bored to fit the bushings they'll be concentric.

Reamers aren't happy opening a diameter by 1/8"; you'll need to drill to about 39/64" before reaming. You'll have to experiment, you may need to go 1/32" under on the drill size.

You do realize that a nominal 5/8" rod isn't going to make a usable fit in a nominal 5/8" hole - somewhere, one of the dimensions needs to be a few thousandths different to make a running fit.

4. It's possible to do some light milling with a lathe; it's also possible to gargle peanut butter;-) If there's any other approach, it'll be more pleasant.

Look at other vendors - most of them offer a 7x12, which is actually a 7x14 when it's measured from the face of the HS. That extra 4" makes a big difference when using real world drill bits held in the TS.

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
