Has anyone built Lautards "Tinker" tool grinder?
How about any other too grinder.  The Quorn looks like a life long
project!  
What about the ones that have been published in the Brit. mag. "Model
Engineers Home Workshop?  Some of these look prety good.  I built some
time 
ago the one Rudy Kauhaupt published in HSM a few yeas ago using a small
piece of aluminum I cast for the head. It works well for tool bits and I
scribed some lines on it and now us it fo drill bits.
But I would like something with more capabilities.

Well, I'll have my Quorn done any year now.  ;-)

I wouldn't call it a lifelong project, but there is quite
a bit involved in making it even though most of
the steps are pretty straightforward and not all that
difficult. The only thing really finicky about it is 
making the spindle, and even that isn't too bad, i.e. 
it's do-able if you have even moderate machining skills.  

I wish I could tell you how it is to actually use, but
Life has intervened in a big way and I haven't had much
chance to work on it for quite a while.  I have gotten
it to the point that I can, with some kludginess, set
it up to grind square toolbits, and based on that 
experience it seems to have a lot of potential. I'm not
sure it's THE way to go for a tool grinder though; I
haven't been able to use it extensively enough yet to form
a good opinion of its capabilities.

I've looked at the Tinker, and rather like the design.  It seems to be
designed to handle most of what I need without all the additional
complexity of the Quorn.

>scribed some lines on it and now us it fo drill bits.

I'm not familiar with that you describe, but have found that for drill
grinding a drill grinder works best - it's got the cam movement built
in and usually does a better job than a flat face grind.  I flat face
grind the little bitty drills, but for 1/8" and above use a drill
grinder.

>But I would like something with more capabilities.

I'm considering building something like the Glendo unit.  I like their
design, but find the $1K price a turnoff.  I know at least one r.c.m
poster got one and seems to like it, but $1k just about kills me.  I
can't see that you get to $250 before the diamond wheels...  (A kit
>from  Hemingway for the Worden grinder, similar in design to the Glendo
unit but using a traditional cup grinding wheel would go for $300 or
so).
