Minimax S31 planer information
Around 10 years ago, I went to the home of a elderly woodworker who had passed away and purchased a dust collector from his son. While I was there, I also bought a Minimax S31 planer which I wasn't really looking for, but looked like a very robust machine and I had always wanted a planer in my shop but never wanted to settle for a portable unit. The planer is a yellow color, stands around 36 inches tall and weights several hundred pounds.
I brought it home and have used it for the last 10 years, but I've been noticing recently that it was leaving a rougher finish and also the feed rollers seemed to be slipping as I needed to push the lumber into the planer so I decided that after 10 years it is time to take it apart, order new knives and give it a through once over. To start that task, I've searched the web and have not found any documentation on the planer at all. I haven't even found any photographs of that model number so it's turned into a mystery for me.
Internally it seems like the feed rollers are gear/chain driven and the cutter head is belt driven. Everything to runs as it should, so I'm thinking the knives are just dull and need to be replaced.
I've been searching for replacement knives, but that planer is not listed anywhere in any online catalogs. The next step was to remove one knife and measure it so I may need to get knives made unless someone knows where Minimax knives may be purchased.
If it helps, the knives measure 12-3/6 x 1-3/16 x 1/8. Those dimensions are also equal to 310mm x 30mm x 3mm.
I'm looking for a source for the same size knives, perhaps in carbide, and would be thrilled if anyone knew where I could find minimax documentation.
