Home-made horizontal borer
I have always been an advocate of the mortice and tenon joint but after experimenting with various routing techniques and a morticing machine to produce them I ultimately decided that loose tenons were an excellent alternative.
I didn't really fancy forking out for a Festool domino jointer so though about a hoizontal borer and Carba-tecs offering looked quite good but what really put me off was having to buy specialist left-hand rotation cutters.
So I got a crazy idea to build my own,The main guts of it is a morticing attachement bough from H&F intended to fit a planer/thicknesser in their catalogue.The motor is provided by my trusty ol Elu mof177e router.
I think using router is a great option as the availability of cutters is huge and this works like a dream with a solid carbide spiral upcut bit.
I am most surprised with the speed and accuracy of cutting joints and probably wont go back to using trditionla methods or my hollow chisel machine.
I will admit though it wasn't nececarilly a cheap build though as It' basically a $400 router and a $250 morticing attachment.

glad you like it and it works well.
usually i find that as a tool maker i leave much to be desired what looks great in my head then on paper never quite comes out hence my forum name
Some people are like slinkies - not really good for anything, but they

There was a farmer not far from here who wanted to harvest seed off Kycuyu grass. He wanted to be able to sell the seed to the turf industry. He was a Yank and fairly cluey. This contraption was built on a very old header with sundry bits from other machines he had on the farm. It was the most ungainly strange contraption but it worked.
I don't know if any body else followed him up and redesigned it but it did exactly what he intended and used to boast it was probably worth over a million dollars because of all the different parts from donor machinery that went into it.
So Mr Mark David if your machine works and you are happy that's all that matersJust do it!
Kind regards Rod

I'm a mad fan of the Festool Domino machine, but like everyone, not the price. I have a Durden Pacemaker with the mortising attachment. I'm hoping that if a set the stops correctly on the mortising table I'll be able to duplicate the mortise needed for a domino dowel.
The main spindle, on the Durden, has a rudimentary collet which accepts a 29/64" drill bit. Domino bits/ dowels are 4, 5, 6, 8 and 10mm.
I've searched the net for 29/64" collets, adaptors and shafted bits (milling, mortising and router) but no luck.
Any help in getting this idea up and running would be greatly appreciated.
David

In response to fulbar, I've included some images.
1. This shaft also has the saw blade attached (it has four slits which would clamp onto the mortise bit). 2. Showing a snug fit 29/64" (odd size!) drill bit inserted. 3 & 4 the outside nut.
