Lock mitre cutter

[chirpychippy]

hello,

I decided to cover my newel
Posts in 3/4 inch oak, I've looked at a few methods of joining the external corners but nothing appeals more than the Lock Mitre Cutter "which I've never used"
Is there a specific size cutter I need for 3/4 inch material?
I've got 1/2 inch router and the trend router table am just not sure what size cutter I need?
Any help would be brilliant, regards Chirpy.

Trends lock mitre jointer cutters range from 8mm- 12mm and 15mm - 25mm.
Not cheap at nearly £60 quid for the larger one and they say cannot be re-sharpened.

Only one side is actually locked. The other side relies on glue strength though granted the surface area is increased.
Accurate 45 degree on a track saw will give you the same result I would have thought. Some glue and a few panel pins?
Or a biscuit jointer?

Cheers Roger298,

The stock I am using is either 4 inches or 5 inches wide, I've got a Makita Rail saw and rails and I know from experience that the rails don't balance well on these widths. Equally the lengths are to short or long to use the clamps so any play will create problems. But that said in principle it's good idea, just not in this application.

I'm not concerned with the cost of the cutter I'd rather spend more to get a brilliant finish than spend less and get a possibly sub standard finish, I am "AR" after all and anything less than near perfect will do my head in.

To digress, I am assuming I'd need the larger cutter then?

Thank you, Chirpy

yep the 25mm refers to the maximum thickness you can cut.
