I'm using the Axminster Shaker Router cutter set.
This is designed for stock between 18mm and 22mm thick. My stock is 18mm. The instructions suggest running through the moulding and groove for the panel on the stiles and then adjusting the height to cut the scribes on the ends of the rails I prefer to do it a better way (and one suggested by someone over on woodworkuk..can't remember who). I also like to use a false fence with the router table.
The approach is to have a false bed to raise the stock high enough to avoid the cutout in the false fence and then when scribing to use another spacer to raise the stock up to the appropriate height - remembering to turn the stock the other way up DAMHIKT.
Here's some I made up earlier.
I do use false fences a lot and always try to label them up with as much information as possible. For instance, here is one for one of the many mouldings used on the Vulliamy clocks I made. Note I also write down the spindle rotation (since after modifying my Kity I have the luxury of spinning in either direction). All those MDFs sheets are false fences.
OK so here's the false fence and false bed fitted.
Next up is to take my 'stock' master and adjust the height of the cutter. The 'stock' master is exactly the same thickness (take a gnats) as the stock I have just prepared. This is critical else you have to start faffing about with changing the spacer plate etc.
I'm breaking this all down for those who've never done this sort of thing before. You old hands will be bored to death!
So then using the spacer plate and a piece of my new stock I will make the scribe. This is another advantage of having 'spares'....in fact, whatever job I am doing, anything that is fiddly such as glazing bars I will make spares because if anything untoward happens I'm good to go rather than have to faff around resetting everything, planing, thicknessing etc.
Notice the square alongside...another tip picked up from woodworkuk (Senior IIRC). The Incra fence does come with a right-angle attachment for doing scribes etc but once you have fitted a false fence you can't use it (design oversight, Incra!). So simple solution. Use a piece of scrap exactly cut with a 90 degree angle. Doubles up as a backer board to stop breakout.
Having that false fence with no gaps for the stock to fall into makes it so much easier. I guess 55mm wide rails do as well !
So here we have our test cut.
Next job is to remove the spacer plate (remember scribe first...that way when you run the moulding through you automatically help clean up any scraggy bits of wood left over from the scribing cut.) and run the moulding through and check that the scribe and moulding match. But will they?
I'm afraid you'll have to wait as I have to go out to look at a job
If opportunity doesn't knock, build a door.
