I got an ok finish not as good as a planning bit but ok with a corbox bit but
the feed was slow and the spindle speed was fast so I’m guessing Richards 300
rpm with a fine feed like 10 to 20 thousands of an inch per rotation would
work. I wound the feed by hand and the spindle by motor, but as
On my model 200 I use a core box and the finish is terrible. A bunch of tiny
scallops in a spiral pattern. I think the travel is something around .030" per
rotation. If I could get closer to .010" or .020" it might not be so bad to
sand out.
Good to know about the ebay bits I've seen
Everything Tim says is totally correct I especially like his ass o meter mine
is just more sensitive I guess :-) and dia defiantly dictates ‘spindle speed
you wouldn’t run a 12inch dia piece at 300 rpm .as for the bottom planning bit
magnates one i think are best good company to deal with too
I just use Magnate brand flat bottom bits such as the most versatile #2704 the
1-1/4" flat bottom. Most I see have the 1º slant. I have in the past bought
these types of bit and have my tool sharpening guy fix them. I've even had a
couple of magnate bits that needed a little fixing. Sorry I
Tim,Thanks for the "tidbit" re: "Flat bottom" router bits. I did not realize this was a possibility for that type of bit. Very interesting.Can you (and any other Group members) provide router bit manufacturers names and their stock numbers for bits that you KNOW have FLAT bottoms?(Conversely, if
What's the diameter of the piece you are turning? The latest instructions are
to cut from the headstock to the tail stock using 1-1/4" flat bottom router
bit. The spindle would be turning counter clockwise and the router is offset
towards the back by a 1/2" or so.
The speed was based on a
Bill,
I am using a straight 1/2 inch bit, cutting from the side. *All I do at the
present time is to experiment. *Has anyone found that 300 rpm is too fast,
and if so what happens, The longest length that I am turning is around 2
feet x 1 1/4 inch dia.
I am taking it steady on the travel as I
Hi Bill
I will put the Tacho on it today, and will let you know,, however the
inverter has a potentiometer on it ,so I can vary the revs. As long as it
does not over heat it can go to nearly zero. The spindle as you know does
not need a lot of power. ( also gives the good Wife's arm a rest
