Varied my Speed

Jun 30, 2004 7 Replies

Just made a birch dish for a granola guy, and while sanding, I thought the dust was throwing a bit more than usual. Normally I can get 90% or more with the DC down and away. Then it hit me - I had been using a pneumatic sanding drum on the lathe on Monday, and I had actually changed speed from



500 to 1000. Two days - bowl, dish, cup-and-saucer and a box on high speed. Can't remember the last time I actually did that, though if I recall correctly, it was when hollowing with the scraping tools.

All you folks with variable speed may laugh, but I just opened the cover and moved the belt back to 500 rpm. That way I can still use my non-HSS tools....


OK. I'll bite and fear the backlash of actually asking you to explain....

"George, why can't you use your non-HSS tools above 500 rpm?"

I must be just an incredible woodturner (cough cough hack and a snort) or amazingly out of (or perhaps up to) date since I've been using my non-HSS tools (some are barely steel) at speeds up to 2000 rpm regularly and sometimes up to 3000 rpm in special cases for years. Who knew!?

I'm kinda curious about this one too. f this turns out to be too obvious, you may need to slide over there on the bench and make a space for me too. Dave in Fairfax

It's obvious to me--if it's not high speed steel, it must be "low speed steel." Move over on the bench.

There's always room, Dave. For some strange reason, those on the same bench tend to slide further and further away.

If I had to guess, I'd say it's going to be something about going too fast will overheat the tools or maybe too much force exerted at higher speeds for those non-HSS tools. Or it could be something obscure and mysterious such as "those non-HSS tools cut better at slower speeds". I'm hoping it's something good. And, no, I've promised myself to not comment on it and especially not ask more questions either. No, really!

But, of course, I hate to guess at what people are thinking. It only gets me into trouble.

explain....

Where's that rimshot when you need it? I've got to get back to work. Wasted just too much time today. Enjoy fellows.

Can't cut a bowl with a spindle gouge, right?

Not sure which is more significant, that I cut wood without noticing, or in the end, returned it to the lowest speed. Guess proper speed is in the mind of the beholder.

Now, had I put a rough chunk up, I'd probably have noticed sooner.

Darn, and I took my monthly shower and everything too. %-)
