I need to cut a one-off round disc of 20mm MDF
Need it to be as perfectly true to round as possible, as will then run a guided moulding cutter around it with router to make it slightly decorative. My son has bought a house an there is a real naff plastic ceiling rose .. fitted to hide hole in plasterboard .. larger than teh light fitting base.
My intents id to make a 175mm round 'decorative' MDF rose , screw it though to a noggin fitted between joists. Paint in white to match ceiling and then fit new light he has bought to it (new light has a 115mm diam chrome base)
I have a router and suitable bits, but have no circle cutting jig for a disc this small ... the trammel bar that came with the TREND T5 is not really suitable for circles less than about 250mm diameter.
I also have a Trend T11 and a router table for it ...
Just looking for suggestions for a simple quick & easily made circle jig.
Seen some great youtube videos but the jigs would takes many Hrs of use ... and too much effort (and cost) of this one off. Plus most of them are for larger circles.
I have a bandsaw .. also looked at options for this - great video here:
Lots of waffle so skip the first 5 min
Nice idea but again too much work for this one off need.
Anybody got a simpler idea for using router for this ?
