Thanks for the chart. I was about to get out the calculator and make up a basic table for my lathe of RPM versus diameter = surface speed, but this is a lot more useful

Thanks for posting the table on cutting tool angles. My copy had been torn in half and I was going to get "around tuit" for a replacement.

The table also applies to Shaper cutter tools with one exception - the front clearance is 3 deg in all cases.

I haven't tried cutting fibre or hard rubber in my shaper so I can't say if more front clearance is needed in those instances.

Cheers

Geoff

I like that nomogram better than my current table based reference. Anyone got a printable (preferably higher res) link to an imperial version so I don't have to do conversions (or mark it up)?

Instead of going the dumbed down photobucket jpeg route,
should I be able to scan to a pdf which should retain the nice resolution that my prints of the chart come out at?

Often there are bits of information like this that I would like to scan and share, but it comes across poorly when posted.

I managed to convert the jpegs to pdf with cutepdf free download.

How do I post a pdf here?

Since nobody else responded, I'll take a stab.

You really can't "attach" it here, you need to find a place to upload it and then link it. There are several general file hosting sites out there that work like Photobucket and co. Or you might be able to use "free" space provided by your ISP (most give something like 10MB with each email or the like). I would offer to host it for you, but I've used up all my "free" (i.e. included in the cost) email accounts along with their storages. :D Perhaps someone with a full on server with plenty of space (and badwidth) might take it on?

In any case, I'm still hoping that an electronic/printable copy in imperial units shows up... Otherwise, I'll just keep using my rough numbers, but the chart is very nice.
