Re: Woodworking with the mini-lathe

 

Vikki,

Good progress, As for the tools, there's a time and place (and use)
for both the smaller and the larger tools. By bigger, I should
clarify "more often, longer". There are times when you'll need skinny
tips. A longer handle will always give you more leverage and tend to
keep the tool from moving you as opposed to you moving the tool. You
know, the tail wagging the dog thing. Also, I can't help but think
that a different choice of wood will also make a difference. Again,
if you could spend just 15 min. with an experienced wood turner(not
me) it could make a world of difference. Just my 2c. ;)

Keep up the good work. :)

Quite pleased with the results!

Pretty sure the "big" chisels are just that - too big :-/.

Next time I use some decent wood :).

Take care, Vikki.


Request for Help with Replicating Posts

 

Yahoo is continuing to work on the replication problem and has
instituted two fixes. It is hard to say whether the problem is gone or
not - they say new posts after 8am on 29 March should not replicate
but apparently earlier posts may continue replicating since that is
clearly occurring.

I have spent hours trying to clear the replicating messages and can't
keep up by myself.

Yahoo allows the authors of messages to delete their own messages. I
assume this applies to replicated messages so please help clean things
up by deleting replications of messages you posted, leaving only the
original.

Thanks, John

The reason J.W.Early was asked to stop is

Re: Woodworking with the mini-lathe

 

Vicki; Those tools are certainly usable, but wood lathe chisels
usually have much longer handles and longer metal shafts. Although I
use the term chisel, woodturning chisels (WTC) are nothing like wood
chisels or carving chisels. If you can't get both hands on the handle
with a grip like a baseball bat, the handle isn't long enough.

It's a safety issue. A turning tool handle is long enough to stand at
the lathe and hold the butt of the handle against the hip, while the
other hand guides the cutting edge near the tip. A catch with the
tools on your web page may rip the tool right out of your hands. The
longer handle gives you leverage and more control.

Search the internet for a woodturning video demo. If you have a local
Woodcraft store, there will be someone who can show you "how to".

Definitely take a look at Woodcraft, and Packard Woodworks

There are several YAHOO groups devoted to woodturning.

Re: Bandsaw v circular saw

 

Not completely related to this thread but has anyone seen any of the
upright bandsaws with a twist in the blade so you can cut long stock
that won't fit in the throat (like a metal cutting bandsaw)? I realize
in these situations the stock can't be very wide. When cutting pvc I
have to take an angle cut, then a 2nd cut to straighten it out.

Hi Group,

Yahoo is having a problem with posts replicating multiple times on
many or all groups. This began slowly earlier in the week but has
accelerated in the last few hours. Yahoo is aware of the problem and
is having difficulty resolving it.

Those receiving emails of 7x12 Group posts may want to shut this down
temporarily to avoid being inundated.

Group members may want to temporarily reduce posting new messages to
minimize the effects of the problem.

Attempts to delete the replicated posts don't seem to have much effect
so I've given up trying to clear the replications and thus keep the
group looking normal.

With a little luck things will be back to normal shortly.

John

If you think we have problems with repeating messages look at the hot

Re: Threading and using the Dial

 

Aren't masonry bolts made for one time use? The ones I've used (in
concrete of all places) were made of soft metal - I wouldn't think
you'd be able to back it out. Your isn't permanent is it?
Ed

This is exactly what I used. Fortunately the masonary bolt used, is
the right diameter for mounting the gears on. Just add a plunger of
some sort and you have a simple indexing attachmeny as well !

Re: Taper - I think I have a problem?!

 

It'd be difficult to weld, since it's cast iron. Even if you had it
brazed, it'd probably warp just to demonstrate the inherent
perversity of machinery;-)

Seriously, one thing that comes to mind is your wooden test piece may
be giving some false indications. Since wood is somewhat elastic,
it'll move away from the cutting tool & spring back to its original
position if you're doing light scraping cuts. My quickie test bar is
a piece of 1/2" threaded rod, 4 nuts & 2 fender washers. Since
you're only cutting the periphery of the washers, test cuts are quick.

Re: Taper - I think I have a problem?!

 

You'd still have to contend with backlash in the actuating screw.
I'll stick with simple direct measurement & adjustment. If nothing
else, it lets the measuring tools feel productive;-)

Hi Roy,

Combining these ideas, an offset adjuster as detailed at LMS could
be made with a graduated scale as well as provision for a socket
wrench on the end. Say an M6x1 bolt and major graduations every 9
degrees, minor ones every 0.9 degrees if you're keen. Then you turn
a bit at each end of a test bar and mike it to determine the
current
offset, tweak the adjuster using the graduated scale and eureka! Of
course, you'de re-check with the test bar the first few times at
least...

Another approach to aligning the TS is to turn a test bar between
centers to measure the misalignment, then adjust the TS off the
lathe. Unlike on larger machines popping the TS off is
effortless
and it allows access to the underside locking screw. To move it
controllably, use a depth mic (or a depth base on a dial caliper)
to
measure the original position of the upper part relative to the
base. With a measuring tool involved it's easy to get it into
final
position without having to make an adjuster.

The boring head is used to hold a short center an easily
adjustable
distance away from the lathe centerline for taper turning without
disturbing the TS adjustment. The downside is losing a couple of

Re: Threading and using the Dial

 

Looking at the scant 4mm protrusion on mine makes me a little leery
of expecting too much from it. I could see some sort of locking
device, either a removable pin or clamping a split threaded piece.

And using a hand crank with a long bar poked through the middle
must
be a PITA. But a nice option when necessary. <G> Good argument for
a
big cast valve wheel!

I just checked. My spindle has a full 4mm of thread on the outside
of the locknut. That should be sufficient to attach a threaded
crank
onto which would tighten under load in the forward direction. That
begs the question of how to secure it to allow reverse. Maybe a pin
into a hole or a slot cut in the spindle end? To avoid loosening
the
spindle lock nut during removal a collet spanner could be used.

Thinking through the keyboard here. Is this the makings of a viable
crank idea?

The fur kids / Shop Cats seem to keep the trolls at bay here, have yet

The 3/8" socket wrench is another story, I think they hid it from me as

Re: Bandsaw v circular saw

 

G'day Rance and Richard.

The sound you hear Rance is applause for good thinking an ingenutity.

I have three cutoff saws. One a gadget with an angle grinder fixed to
it, next a freehand angle grinder and finally a hacksaw. Of the
three, the hacksaw gets the most use because it just hangs over the
bench. I like the exercise, cuting through a 20mm stainless steel bar
rhe other night only took a few minutes. Sure if I was cutting an
80mm bar I would be looking for some mechanical assistance.

BTW This reminds me. When a child, the railways were redirecting the
mainline tracks across the road from my parents home. It was rush job
during a Sunday morning "occupation". To cut the existing rail two
navies fronted up with an over size hand powered hacksaw and a packet
of blades. The rails were 94lb/yard, so not light section by Ozzy
standards. I recall my father's incredulity at the situation. They
commenced cutting just before we went to church, they had the rails
cut through and were joining them up by the time we got back a bit
over an hour later. They had a hand power drilling machine for the
fish plate bolts as well!

THIS MAY COME IN HANDY. I have found that cut-off wheels designed for
aluminium cut brass like butter, better than the general purpose
wheels.

I have also used my variable speed jig saws for cutting out shapes in
steel, brass and aluminium. (As usual I can not comment on how
techniques work on aluminum as this metal is not available in Oz
except in scrapped objects from the USA!)

One good turn deserves another.

Ian
