cheapo mortising machine

They have at least three listings on Harborfreight:

I do not buy many power tools from HF but my mortiser is an exception. They ran an ad for a $99.00 mortiser and in a weak moment I bought one. You know what? It cuts square holes! I have had it 4 or 5 years and would offer the following:

2) The three chisels they provided are similar to those provided with the Delta drill-press kit and they do a pretty good job (1/4", 3/8", 1/2"). They are sharpenable with a diamond cone sharpener.

4) The stock hold-down attachments absolutely suck. You can get there but they suck.

6) The bushing that fits inside of the main body casting, that also accepts the chisels seems soft. I have leaned it and the inner race with emery cloth a couple of times.

8) The base is not aligned well with the rest of the machine - Oh well what can you expect?

Now for the Donald Rumsfeld questions/answer session:

Is this the only mortiser I will every own? Lord I hope not!

Has it be a useful addition to the shop? Yes. A lot better than nothing!

Do I consider it to be one of the better tools in my shop? Get Serious

Can I do serious mortising on furniture projects? Yes, but I take some time to make sure the chisels are tight in the head and I supplement the Mickey Mouse hold-down hardware with clamps. Some day I might fabricate better hold-down hardware -- or go buy a better mortiser.

PS: I saw one in a HF store this past year for about the same price.

go back to northern tool and do a search for "mortising" it will bring up the drill press mortising attachment and accessories.

You really think China wants spoiled lazy American women . . . . They already have the best pussy . . . .

It only seemed that way ... might as well go ahead and load up and take aim at your foot. There is no more worthless tool in the shop than a cheap hollow chisel mortiser.

Hello,

I have the HF machine, brought it for $80 or so (on sales for $99 + 20% off coupon that I found at:

I have made around 35 mortises at the moment, from pine to black walnut to Jatoba (talk about a hard wood!) and am quite happy about it. like most HF tool, it needs a little bit of work to be great (such as sharpening the chisels a little bit more and creative work on the fence (hint, increase it's thikness so the hold down works better)...

for a tool that I use around once every 2 months, I am happy...

You need a router and some practice making perfect mortises in a MUCH shorter time. The mortising machines might have a place somewhere but after doing one project with my Delta, I very quickly learned the "router way".

Agreed. I used to have a dedicated mortiser but I used it so infrequently and when I did use it, it took more time to set up than it did to cut the mortises that I ended up selling it to a friend who would use it more than I did.

Mortises are simple on a router table. Ten seconds with a straight cutting bit and a corner chisel and you're done.

I don't bother with the corner chisel in a blind mortise. While I'm fine tuning the tenon with a shoulder plane, I round the corners.

How can you live with yourself knowing you took a shortcut like that? Think of the shame it will bring you your family if this is discovered during a restoration project a hundred years from now. It would be like finding out that Michelangelo used an air brush in the Sistine Chapel.

Ssssshh! Now you know the secret of the DaVinci code!!!!!!!

They have found a compressor run by a bellows in the chapel store room.

Sorry... He Did Use a Airbrush to smooth the edges.

Edw>>tuning the tenon with a shoulder plane, I round the corners.

Why not simplify even more and use loose tenons? (At least where the small strength difference isn't critical.)

at your foot. There is no more worthless tool in the shop than a cheap hollow chisel mortiser.

What's the dif between cheap and notsocheap then? The steel in the chisels maybe?

Certainly within the realm of possibility. The oldest known instance of use of an air brush was in some cave dwellings in France, IIRC.

I could believe it. I've made some louvered shutters with a plunge router and concocted jig, but - what's the technique for mortising using a router table, if it's not too much to go into? Is it time to invent a foot-operated mechanism for a plunge router in a router table?

Refer to my long-winded post regarding my HF machine above. I think the difference is just the materials used in the whole thing. The bushing between the body and the chisels seems soft and has to be dressed with emery cloth now and then to allow the chisels to slide in easier.. A lot of the threaded hardware has been replaced with better stuff. The cover on the base was a wood-looking paper.

Actually, the chisels are pretty good. They look and cut like the chisels that came with a friend's Delta, drill-press mortiser. They seem to hold an edge and can be sharpened with a dimond cone sharpener. The counter price at HF is about the same as Delta chisels.

I imagine it involves just plunging the wood onto the bit, taking multiple passes.

Already exists:

Very nice. Now I could see that setup adding some speed to the operation, especially with a depth index on the router.
