Template Copier

Monday, October 13th, 2014

The idea for this mortiser add-on has been running through my head for a few weeks now. I wasn’t sure how well it would work and I couldn’t resist trying out the idea any longer.

The templates are secured by the two bolts pictured above.  An aluminum stylus rides against the template as the mortiser is moved forward and back.  So far I am pleased with the results and I can see several practical uses for this add-on.  The add-on will not get in the way when I need to use it for a standard mortiser.  Yippeee!

Finished the X-axis Table

Wednesday, October 6th, 2010

I’ve finished the X-axis (left-right motion) table for my mortiser. Tomorrow I should be able to knock out the Y-axis. Not too much left and this thing will be up and running.

(Compare the picture below with the CAD design in the previous post to see where I’m going here.)

I used a 13/16″ forstner bit to sink the 1.25″ long bushings. They are held in place with a washer over the flange which is secured with a screw. One concern I have is that the wood fibers that hold the sintered brass bushings will wick out a lot of the oil. I will have to wait and see if this becomes a problem or not.

I plan on protecting the rods and bushings from saw dust by wrapping the edges with a strip of wood and maybe weather stripping? I’m not sure how to do this yet.

Thanks for looking and comments are welcomed.

X, Y Problem Solved.?

Monday, October 4th, 2010

Ok. I came up with a design for my X,Y tables for my horizontal mortiser that doesn’t require drawer guides. It utilizes steel rods and sintered bronze bushings. I ordered the rods and bushings today and this thing should be finished soon!!

The top table will move freely on the top two steel rods and the bottom table will do the same (on the bottom rods). The bronze bushings should slide like melted butter.
