Router Modifications to Allow Cutting of Woodworking Joints

This follows from my build log discussion on the subject; http://www.mycncuk.com/threads/6565-...4514#post64514

Sequence of events;

1. cut hole in table to leave approximately 200mm square hole for workpiece.
2. Make table insert to restore bed to one flat surface.
3. skim top of table insert with router.
4. manufacture plywood support arms, 50mm wide, 70mm high
5. drill all mounting holes using machine while keeping same zero datum point.
Holes in, table, table insert, support arms. Counterbore support arms holes and table insert holes. Fit 8mm threaded inserts into table.
6. Check machine to ensure spindle is vertical in all planes. I attached an engineering square to a 1/2" cutter and used a piece of 6mm plate as a feeler gauge. Checked all round 360 deg. circle.
7. bolt support arms to table, skim front faces and top using machine.
8.Cut out and attach workpiece support cheeks. Cutaways allow 100mm throat clamps to be used for both narrow and wide workpieces. Three clamping positions are available and workpiece can be positioned in X direction or Y direction.
9. Check support cheeks are vertical using a straight edge from spindle and try-square from table top, glue and screw in position.
10. Seal all bare wood with clear lacquer.

The not so nice looking slots near the top of the support cheeks are to allow fixing of a T slot rail, which is not yet in my possession, this will allow attachment of jigs such as a 45 degree ramp.

Changeover from flat bed to jointing jig and vice versa is under 1 minute (assuming socket and screwdriver are on hand)

I lost some of the T slot due to this modification but it's not really a problem

Yes but I bet I can cut them by hand faster.

Eddy thought that ages ago before building machine it was mentioned about making the gantry go past the end of bed so edge work could be done. Didn't you do this.?
Or have you got another reason for doing it this way.?

Can't remember seeing that, or thought it wasn't needed, anyway didn't do it. I don't have a big use for this but it was a good little project.

Bet you can't to same accurecy and do it repeatably for say 12 draws.!

Regards your fixture Jig do you realise that you can create and save a Fixture offset for this so you don't have to mess around finding Zero.?

Yes, plan using G55

Great job, looks very nice and its a handy feature to have on a router.

maybe

but i would say, its a bit hard to cut them quickly
with a cuppa in your hand or a cold beer :)
