Actually trying to cut a 6mm slot into acrylic tube as an edging to
sheet.

Need a straight 6mm cut through the 2.5mm wall of some acrylic tube,
how do I mount tube or router to enable a straight cut?

No don`t have a router table , though might be a ble to borrow one ,
how would hlold tube straight whilst feeding?

Any suggestions gratefully received, yes do have angle grinder, think
it will probably leave wider cut than 6mm ;-)

Cheers

Use a vise with vee cuts to hold the tube and jury rig a flat surface
above to run the router on or you could try drilling round holes the
diameter of the pipe in some square pieces of wood and then sliding
them up the tube. These would hold the pipe flat whilst passing it
over a router table.

You don't say the diameter of the tube.

Either router-out a (square-sided) trench for the tube to sit in, in a
piece of scrap timber, or make up a trench profile from other pieces
of timber.

Doesn't matter if the trench is too deep, but mustn't be too shallow,
and the tube should fit in the trench snugly.

Your timber jig doesn't have to be the whole length of the tube, just
long enough to cut a section, and then reposition the tube.

If the tube isn't a very snug fit, you'll also need some wedges to
stop the tube rotating in the trench (or even gaffa tape may be
sufficient).

The router base then obviously rests either side of the trench, whilst
the bit is plunged into the trench, down the centreline and into the
tube. You may need to use a batten or the fence to remain centred on
the tube.

Be aware that as you slot the tube, it may be less firmly held in the
trench.

What diameter tube?

Need a straight 6mm cut through the 2.5mm wall of some acrylic tube,
how do I mount tube or router to enable a straight cut?

One method that springs to mind is to use a ball slot cutter on
a router to make a channel in some wood that the tube fits
snugly into. Clamp the tube at one end. Running the router with
a 6mm straight cutter along the same guide as used to cut the
channel would guarantee that the slot in the tube would come out
central.

Requiring somewhat less specialised cutters, if you have an
ordinary straight one the same diameter as the tube, rout a slot
the same width and depth to take the tube. This doesnt guard as
well against the cutter distorting the tube, though.

Big one-off square-tubular clamp made of scrap MDF, lined with foam
underlay. Maybe a square-U gutter. The clamping can be simple - just
woodscrews to pull the sides together. Then run the router freehand,
guided with the fence on the edge of the jig.

Fit wooden bulkheads at the start and finish otherwise as the slot
progresses the grip on the tube is lost.

That looks like a good way to progress, tube is actually only 15mm
O.D. 10mm I.D. 6mm slot is to clip round some 6mm sheet as an edging,
intial tests are encouraging ;-)
