- Jun 1, 2010Silly silly....
Who said work from a 109 had to be bad because of the source? Someone is
putting words in my mouth..... perhaps projecting their OWN feelings about
the machine onto me.... Which same I do not appreciate a great deal......
My point is that working with a 109 has so many un-necessary limitations due
to the basic design of the machine that it is a royal pain..... Size is
obviously an issue which is inherent, we won't blame it for it's size... a
machine is or is not a 3" (6") machine. But, other things, such as the tiny
0.5" size of spindle, the lack of any dials, and the uselessness of a dial
if you DID put one on, the extreme noise from teh back gears, the severe
limits on depth of cut, wear from poor geometric layout and lack of wipers,
etc, etc, etc are quite limiting.
The design choice of a 24 tpi (non-integer feed per turn) crossfeed, when 20
tpi was a sensible alternate, is really the worst..... it is hard to
change, and completely defeats the idea of a dial. I put a dial on mine,
made on the 109, at that, but could not get around that 0.0416666 advance
per dial turn... after a while of figuring out how many turns and divisions
made 78 thous, or the like, I was just fed up. Changing the tpi was not
something I wanted to do just then, although it could probably be done by
boring and sleeving.
Yes, each "complaint or quibble" could be laboriously fixed......several
dials, new crossfeed and compound screws, etc, etc, but it seems like a
lot of work to sink into a machine that does not pay it back easily. I
opted to sell mine, and even then, I had to tell several folks that I
wouldn't sell it to them, because it would not do what they wanted.
The basic machine is limited, but usable. I had one, and I made it do
things that a 109 cannot do. I early-on made it a follow rest, and that
one thing improved operations a ton. That and throwing the lantern toolpost
into a corner, using a shop-made block toolpost instead.... LARGE
improvement from those.
But I'd rather use a larger 10" machine for most things, and my $25 Boley
watchmaker's lathe for small stuff.. BTW, the cost to me of the Logan, with
accessories, was within $40 of the highest cost I had (up to then) seen a
109 sell for..... and I have since seen a Logan sell much cheaper, and a 109
for more. So the cost differential is definitely not prohibitive.
Use whatever you like.
BTW, a hair shirt is an uncomfortable and scratchy sort of clothing,......
another version of "sackcloth and ashes" as self-imposed punishment for
sins..... and thus strangely relevant here....
