Tool Talk poll - tell us what you think!

[mklotz]

Allow me to suggest another topic that would be of interest to me especially and hopefully to others - miniatures.

We've had a couple of these already, e.g....

http://www.homemadetools.net/forum/l...hine-gif-69222

but there must be many more out there. In addition, specialized tools for modeling and miniatures is a rich field to plumb.

Jon, how about a topic, yet to be named, which is a depository for suggestions for a tool that "should" be made.

It is not uncommon for me to need a tool which I have never see before, I don't know the name of, I don't know whether it's commercially available, or whether it even exists.

This would allow one or more of us to advise if such a tool even exists and if so suggest where one might be for sale.

An example is a tool to countersink a drain hole say on the inside of a thick steel plate tank which is fully enclosed.

The need to countersink the inside surface of the hole is to allow the tank to drain absolutely completely, the hole having been drilled after the tank was welded up and fully sealed.

Such a champhering tool would be collapsible to allow access through the hole from the outside then expand to expose a cutting edge for removal of the inside burr, only to collapse again for withdrawal. I hope this example is clear.

Anyway my suggestion is a topic where requests for a tool such as this, and of course any type of "unknown tool" can be discussed.

What do others think?

Such collapsible tools exist, chiefly the Cogsdill or the Huele. They'll deburr, but a full countersink would take quite some time.
But a second remedy isl known as a 'back countersink'. It's driven by a bayonet style pilot but you'd need to attach and remove through an access built into the vessel.
So, there is a work around for that as well. Drill [even hole-saw] a decent opening for a flanged machined fitting that gets welded in. A depressed back side would drain effectively through any size opening desired, sealed by NPT or NPS threads.

I have no connection with the following companies other than having used their or comparable tooling; plenty more exist.
