Topic tags/keywords: router chisel drill press

Hi all

Once again it is that time of year that I look at new tools for the shop. I am looking at the Grizzly G0645 Mortise Machine.

I was wondering if anyone has one and what their thoughts on it were. I plan on making furniture with it and most likely light duty work.

I was also looking at the Northern Industrial Drill press mortise adapter since I am not sure if I will really be using mortises other than the furniture.

I also did consider using my router, but I don’t think I will be comfortable using it for this type of work.

What do you think?

That’s the mortiser I want to get. One of the wood magazines did a big bench-top mortiser shoot out recently (sorry, I can’t recall which one), and that model came out looking near the top for price/value. Add to that I like Grizzly and have had good experience with the 14” bandsaw I got, and that’s the one I want. Sorry I don’t have any practical experience to provide, just a long-winded “me too”.

From what I’ve read, the drill-press mortising attachments are a disappointment, and most end up getting the dedicated machine.

same as Delta/Jet/Others…comes with 4 chisel/bit sets (same as Delta/Jet/Others).

I use mine once and a while…and have to say I have no remorse on buying one (unlike a few other tools I own). It won’t make a perfect mortise but “perfect” is a “relative” term on a $250 machine

I would stay away away from Drill press attachments the ones I’ve tried are junk. I own a good amount of grizzly tools but have not use their mortisers. They might have a review here or on Amazon.

I’ve got the delta. I’ve used it twice. Buy a good set of mortise chisels and save the shop space.

Don W…that machine is the same as all the others and the footprint is no bigger than a pair of size 12’s side by side. If you want perfection, use it to “get close” then clean-up with hand tools (never seen the need myself but then again I’ve never gotten crazy over a 1/16” here or there when it comes to wood). And no I can’t balance a nickle on my TS or BS but quite frankly I know what I paid for and they have met my expectations.

No regrets on my Delta at all. Besides the several mission style tables I have built, I also rebuilt a deck railing and the entire balcony/stair railing inside our new house. I’d have to say that even now getting little use, it was one of the best tools I ever bought.

I’m not nocking the tool, it works like it should, but in my opinion, unless your going to make a lot of mortises, and time is of the essence, there is probably a better place to put your money. Hand cutting a mortise doesn’t take that much time, and most pieces don’t have a boat load of them.

I own that mortiser, I would buy it again. I haven’t used it as much as I would like because I am buiding base and wal cabinets for my shop, so doing alot of dadoes and face frames, but I used it extensively on some oversized doors I used on a builtin in my basement office. it was easy to set up, the bits are sharp as heck, and the unit slides up and down nicely, after a decent lube job of course.

What surpised me was the weight of the thing. I think it ships at 75lbs, and as I was building my cabinets I was moving it around to get it out of the way… good lord, its a load!

Go for it!

oh yeah, put the DP attachment to bed…. your drill press is designed for precision with sharp bits and rather light pressure from the handles…. as you will see the mortiser while precision is a wood boring beast… they handle is robust, its compact and designed for mortising… its also got a hold down on the fence system than keep the piece on the table when you pull the bit out… you’d have to rig up something on the DP for that.

Just ordered that mortiser yesterday, waiting for it to ship. I think it was Wood magazine that did the review, and the Grizzly came out best value. Have been bugging the wife for the last year (anniversary, birthday and last xmas) to get me one. This xmas she finally said ok and I placed the order so as to not miss out.

I want one too. Looking AT A JET (JBM-5), everyone says no to the Drill Press attachment.

I made a jig to run my plunge router on legs I spin off my lathe, corner chisel to finish the holes. That works great.

But I have been doing a lot more through mortise joints with pin locks.

Currently, I drill out the center with a good clean forstner bit and use a corner chisel to finish the holes, takes time but works fine when you doing one to four of them. Any more it starts to suck.

The only bench top mortiser that impressed me is the Powermatic. That is a sturdy model with roller wheels.

I have a Delta and it’s ok, but after breaking several parts on it, I upgraded to a Jet floor mortiser. I really like the X-Y table, and would have a hard time giving it up. I use mine on every project, but a bench top model is a good compromise for occasional use.
