Default Best way of cutting small mortises?

Question from someone new to working at a small scale.
  • Make a small chisel and cut it by hand
  • Drill and clean with a knife
  • Other
?
if I was doing it full scale I would simply cut them with a chisel.
Thanks

I make small chisels from old needle files. Then drill out some of the mortise, finish with the small chisel.

Keith --

Like Paul, I start with a small hole.

Then I file out the mortise with a square micro file and then use a triangular micro file to true up the corners.

If I'm making a little larger mortise, I use these:



I found these at MicroMark several years ago.

You will have to spend some time getting a proper edge on these.

(I have no connection with MicroMark other that I spend money there.)

Thanks for the comments from you both. i think that i knew all along that I would need to experiment and find my own "method". I have a large collection of very old awls that I don't really use. I was thinking of using these to grind into chisels, or fashion my own from scratch using silver steel.

next issue to solve will be thae lack of a lathe. But I think that I can modify an old picador drive that I used asa grinder in the past. It will become a bit like the Picador Pup as used by John Thompson.

Hi Keith,

I make small chisels from Xacto blades, and use the Xacto blade holders. They can be ground to any shape you desire using a grindstone in a Dremel or similar, and finish sharpened with a wetstone. The steel holds a good edge for quite a while.

Cheers, Danny

Thats a good suggestion. Exacto does have a couple sizes in chisel type blades. They are a bit to wide at times so I use a set that I got from Micromark that are scalpels. The are very small. Your suggestion would eliminate having to buy the scalpels and could be made to the size needed.
