Craftsman mortiser

[eddy merckx]

I was in Sears today returning some stuff. While trolling through the stationary power tool section, I spotted their hollow chisel mortiser. It retails for $199. It looks massive and seems to offer serious leverage. It also seems to have a pretty big table. Does anyone own one of these? I couldn't find any mention of one when I searched old threads. I'd be interested in people's opinion of this thing.

Thanks, Eddy

Seriously, nobody has tried one? This appears to be a new, heavier duty model and looks pretty good.

I just bought the 21907 but is still in the box. One thing I can say is it ways a ton.

Do you know what how many amps the motor is on that model? I can't find the specs on Sears site.

6.4 amps

I believe it's around 6.4 amps. I'll check to make sure exactly when I get home tonight...

I just bought one of these over the weekend. Used it last night on some oak with the 1/4 inch chisel. Worked very well.

Note however....I should add that I bought one on Sunday, brought it home, assembled it (very heavy!), turned it on, and watched it spin for about 3 seconds before my ciruit breaker blew. Reset breaker, and morticer would not work. Just a slight humming noise from the switch area. Shaft spun freely, and determined there was no dead spot. I believe it was the capicator located in the switchbox which had blown. Oh well.

Anyhow...took it all back apart, attempted to put it back in the box the way it came...ugh! went back to store, and explained what happened. Decided to give it another shot, took a new one home, and well, like I stated above...it works very well.

Minor gloat to follow...Last week, item was selling for $219 at my local Sears. This past Sunday $179. After returning and getting one that worked, sears gave me another $20 off for my troubles. So basically $159 (and couple of minor headaches) It was worth it for me...and I'm quite effecient at assembling these things now!

I am quite pleased with it (as much as one can be having only used it for about 30 minutes so far.)

Don,

How was the process of putting this thing together? Was it pretty easy or was it a PITA? Do you have pics you can share that has better angles than what is posted at Sears website?

Thanks!

not hard

To be honest, the manual isn't the best out there. However, it is good enough to work with. It's really not too difficult to assemble, as the pieces seem to intuitively fit where they belong. (it is quite heavy though!)

If you are going to put one of these together, do yourself a favor and put the handle on first, so you can crank the main body up a bit to install the "shock absorber". That thing is dang near impossible to compress otherwise. Do remove the single limiting set screw on the upper left (facing you) behind the motor. (this screw is a stop point, so as not to raise the the main mortice too high out of the track). Doing so will allow you to install the shock absorber without trying to compress it first. Then remember to replace screw.

It took me about 30-45 minutes. That included the time it took to wipe down with kerosene, (or WD-40 as the manual suggests) to get the protective oils off and wipe with some johnson paste wax. You will need an 8mm open end wrench (or socket), but they supply the rest of the tools needed - hex wrenches.

Unfortunately I do not have any pics, as my camera has decided to stop working. (guess that'll be the next purchase).

Let me know how it goes should you decide on purchasing one.


Good luck!
