Re: A new (and slightly off) topic

 

Generally, you never want to machine wood on metal lathes and mills.? This is the "common" advice.? It is true that there is a rather high risk of rust as wood, unlike metal chips, contains moisture.? Also, you tend to get some very fine dust that can be hard to clean out of everything.

That said, they are just machines with things twirling around and one might ask how is that different than a wood lathe or other woodworking machine with exposed metal.? Of course, in a metal lathe, or mill, there are a great many more nooks and crannies.

I have machined wood on the mini-lathe and mini-mill (but probably would try hard to avoid that on my larger lathe and mill) but first I wipe down the machine really well so there are no thick films or puddles of oil or anything.? And when done, IMMEDIATELY clean the machine and re-oil it.

?Dear Gentlemen,

1. If you feel this is too far off the topics generally covered, then may I ask you to simply delete it. I do not want to generate a lot of wasted time and effort on is/is not appropriate for this group.

2. This subject may have been answered before, so if it was then sorry, but how do I access the previous content from maybe 10 + years ago? As I can’t remember it in the last 10 years or so when I think(?) I joined the group.

So in fear and trepidation ‘May I ask’ ???
I need to make some small but accurate ( but not precision,) hardwood blocks, approximately 50mm x 50mm x 20mm thick (2in. x 2in. x 1in. thick). They have rebates and angled faces etc. I have sufficient and appropriate router cutters, plus collets.

So is there any technical reason why I can’t mill or rather rout them on my milling machine. It will be so much easier and much more accurate. They will probably be made of beech. (I can’t see any reason not to, but I have never tried it before? )

Thank you in advance (but with fear & trepidation),?

? That was my instant thought as well. Something like this:?

It won’t work as a crank AND dividing head for your use case, but for the times you need to crank the lathe by hand (like when making a large thread or worm gear ) ?it will work better than trying to get enough torque to do it with the lathe motor.

Christophe has a bunch of really elegant tools and builds.

Hi Johannes. You don’t need an extra crank.

As your dividing disc uses the outer edge for measurement. Just drill a suitable hole in the disc, with a suitable bolt and handle, this can be attached when you need it and removed when you don’t.

I have a big dividing disk on the left side of my lathe. ?So no space for the crank.
However, after some days use, I will use my new crank much more.
