on my middle spiral what I did was use magnates core box bit number 810 the
11/2 inch diameter core box bit
and ran it down the centre of 2 pieces of wood then glued them together to
make one piece with a 11/2 inch hole up the middle then made a sacrificial
piece that fits neatly up the middle a genital tap in fit not too tight and
not loose .. then I made a cap for each end that were a nice tight fit so
the job didn't spin during machining then put all that in and made the
hollow spiral I ran the job in a steady rest too nothing special jus a block
of wood with a half round cut in it on the band saw the bolted to the revo
just to give the spiral a little extra strength and of coarse when doing the
hollow with the strait bit little cuts I machined right down till almost
breaking thru with each start of the pitches then I took the last little bit
out on each. there might be a better way to do all this but that's what I
did and it worked great every time.. post pics when you do it

Thanks Bill,the outside spiral, Does that mean you drill out the
center first and then cut your spiral with the sacrificial
inside,that's seems to be why I have chunks flying off and sod it
another wasted log,boy what a thicko I am,as I said this forum is
invaluable,keep chippin,MAC.

the best thing it needs is a dam cross slide leadscrew and steady rests
one
or more make a great differance to fight vibration too I was always going
to
make 2 ajutable rollers that run the whole length of the revo as well as 2
shorter ones for different diameter work as a lot of the work it does is
small diameter 1 or 2 inches

Ps a tip when you do the spiral in a spiral make sure you make a
sacrificial
insert for all the way through the middle of the hollow before you do your
spiral or most assuredly it will fly to bits my first one did

Great to hear! I think a better locking system is in the future for the
Revo
owners. Some thing quick and solid. A full depth, single pass cut is a
lot
of strain on the equipment.

Evenin all,I have been out in my shed using the info from TIM BILL,
and Lil /td. yes I do get drift on my cross slide ,cause ,vibration at
high revs.so now I consciously make myself check all locks and even
the stops,this has made a difference,but this just goes to show you
can't let your concentration drift,as to the maths,well never been
great at that anyway but I use pencil and paper instead of mental and
I now get the hang of it I think,I 'm trying it out tomorrow and
hoping for the best,lucky I have bought from Roger a good selection of
cutters,just need a few more,lucky I had a good selection of 1/4 inch
shank cutters,because Roger sold me a tool that could use both 1/2
1/4 saves a lot of fartin about with the chuck,thank you all for your
kind help,and Tim I have now found the demonstrations on the videos on
youtube, a great help. MAC
