a few questions


 

Hi gang!
I've been playing,er, working with the lathe and learning a
lot....now fer some info.

1- What type of tool is best for what job?
considerations: cost, main material is plastic (PVC), some metal
involved to keep if interesting.
is there a general purpose tool for most use?
HSS or carbide....pre-made or grind my own?

2-Is there a way to hold square or odd pieces in a 3-jaw chuck?

3- Is there a good book to learn these things from...i.e. 'Metal
Lathes for dummies"

4- Suggestion for a good 1st time real project, thats easy!

Thanks , Matt


 

Matt,
There are lots of books out there. Check your library first if you
want to save some money! Here's a link to an onsite selection of
good books on machining.



See #15 on the list in particular for one on "Workholding in the
Lathe" regarding your question #2. Odd shaped pieces are best
handled in an independent 4-jaw chuck, or by mounting them to a
faceplate mounted to your lathe's spindle.

Online, MIT has a nice set of pages with some general machining
tips, including some video clips that help you see what they are
talking about.



Regarding tools, I find HSS toolbits best for general all-around
use (for aluminum, brass), but there are different bits for different
applications and materials.

HSS is good for most turning. I only recently used a carbide
cutter for the first time with little difference, but I'm not very
experienced. Of course, you have to grind the HSS blanks.

2-Is there a way to hold square or odd pieces in a 3-jaw chuck?
Sparey mentions this in his excellent book "Amateur's Lathe", but
also mentions not stressing or straining the self-centering chuck.

3- Is there a good book to learn these things from...i.e. 'Metal
Lathes for dummies"
The book mentioned by bflint, "Work Holding in the Lathe", by
Tubal Cain is also excellent, and Wise Owl is a good company. They
also have Sparey's book.

The www.mini-lathe.com web site, by Frank Hoose is an excellent
source of information on the mini-lathe.

4- Suggestion for a good 1st time real project, thats easy!
The first thing I made was a cylinder for a small engine that I
just designed on the fly. I made it of 1" aluminum round stock with a
1/2" bore, tapered exterior with fins, a small unfined area ending
with a crankcase mounting flange, and a gasket surface for a cylinder
head at the other end. Finished length is about 1 3/8".

You can see model engine pictures at websites by search for
various things, like model engine, or Sparey diesel, and other similar
things.

For most stuff, a well sharpened HSS tool gives the best results.
However, there's a lot to be said for the convenience of a pre-ground
carbide tool. HF sells a small insert style set of holders, the
inserts are appreciably nicer than the cheap, brazed shank tools.
The 3-jaw is mostly for round/hexagonal pieces. It's possible to
hold squares in it, but, they're off-center & not very secure. A 4-
jaw can hold just about anything to whatever degree of accuracy
you've got the patience to set it to. There are some 4" body ones
that are more capable than the 3" body sold by HF, Grizzly, etc.
The classic lathe book is, "How to run a lathe" by the Southbend
Lathe co. Lindsay books has it & lots more reprints of old books.

Hi Matt,

I'm new to lathes too so this may be a case of the blind leading the
blind, but as a first project I built Rick Kruger's tailstock
camlock, see:


lstock/

This was reasonably easy to build from scrap, I used old bolts for
raw material and a piece of brass rod I found for the lever. I built
the version with the lever behind the tailstock, drilling a hole
through the web, an option Rick suggested. By having the cam shaft
go through the web it is constrains the vertical shaft from twisting
so a large washer was adequate as the contact for the under side of
the bed; Rick used a more elaborate contact with a setscrew to keep
the vertical shaft from twisting.

Since I don't have a 4 jaw chuck (it's in the mail...) I put a shim
between one jaw and the part as an offset to make the cam.

Overall, it's simple (once you see Rick's design), fun to make and it
works great.

I found this link to be really helpful and I wish to thank John for pointing me to it.



It's a good teaching reference,

Here's an alternative design. Main advantage is that
the lever is out of the way of the compound.

I recommend learning to grind your own tools. You
will find that you can grind many specially shaped
tools to solve all kinds of problems. It's not hard -
just buy about 20 blanks and dive in. Here are some
links that may help:

Hi Frank,

Thanks for the comment. Sorry I wasn't clear about the handle
location. I did put the handle in the position shown on your site -
it seems more convenient there - but used Rick's mechanism for
actuation. I have since posted a picture on my site:



I like the cam concept a lot and will try to use it to make a
variation of Vikki Ford's saddle lock. It seems as if this would
allow locks on both sides of the saddle, actuated by one lever,
without too much difficulty.

Very nice, John. I love the camlock tailstock - it's
a huge timesaver and just a lot more pleasant to work
with than the wrench & nut arrangement.

I checked out your website & noticed the info on
microscopy. My dad bought microscopes for me and my
sister for Xmas when I was about 10 which began a
lifelong fascination with them. When I was in HS I
bought an oil immersion scope with a mechanical stage
from Lafayette Radio. It took weeks to arrive and I
remember coming home from school every day looking for
the much awaited package. When I finally got it I was
really excited - spent many happy hours with it. I
sold it some years later when I was newly married and
needed money. Sometime in the next 2-3 years I hope to
buy a good used microscope and get back into it.
