I don't see the video, is this a case where you need to be a member to see it or am I missing it?

Well, your friend is lucky to have a friend like you. Very nice work.

Thank you. He had seen my work and asked me if I could do it since real shutters were very expensive. BTW these were for inside in his pool room. I told him I would do it for material cost. I wanted to do it for my education. The material cost around $100, clear pine in 4/4 and 6/4. In the picture that was for one window so there were twice as many (8 panels). I gave them to him and said you owe me $100. He gave me a check for $300 the next day.

When I opened the link I could not see the video frame either, NoScript was blocking it.
When I enabled scripts for that page, the frame for the video came up but I still can't play it, because, Adobe Flash no longer supports Linux and I wont enable the vulnerable "old" version.
It would be nice if web page developers would switch to HTML5.
Anyway, try enabling scripts and you should be OK.

The mortising tools as they come from the store are not ready for use. They have an edge but they are not sharp. If you want them to cut they have to be sharp.

You need to have pretty much a mirror polish on the out side of the chisels and then use the supplied grinding wheels to touch up the insides, debur and then make sure you have about a dimes worth of space between the bit and chisel.

The table will need to be braced, on my 500 I notched a 2 x 4 and put that under the table edge for support. They make a real one or if you have a 510/520 use the legs.

I takes a good deal of pressure so it will be a workout using any drill press type system but they do work.

Like most of the other comments about routing these I agree it easier that way but again you can use the system you have but it will take some effort to get it ready and to use it.

Lee Valley sells a nicer set which I have heard work but I have not tested that out.

Ed,

I am in total agreement. I use two or three paper thickness for the bit to chisel clearance.

Your sharpening advice is spot on.

I use the telescoping legs to support the front of the table and I cut two pieces of aluminum angle to support the table carriage.

I made a set of shutters for a friend at work. These were inside shutters for two 4'X4' windows. It ended up with 256 louvers for the 8 panels and over 1000 mortise cuts just for the louvers. The wood was clear white pine. The louvers were quarter sawn 1 1/2 X 1/4. The tenons on the louvers are 1/4 X 1/2. The picture of the stiles only shows one cut for the mortise for the louvers. I moved the fence and did it again.

The point is that the SS in mortising mode works. Is it a Powermatic dedicated mortiser hog? No but it works. Sharp bits are the key as that is in any wood working project.

WOW! How did you cut all the louvers? I would have gone buggy!

Yes it was a long process. I use 6/4 clear white pine. The louvers were cut off the edge essentially making them quarter sawn. The finished thickness is 1/4" via the Performax drum sander. Next all four edges were rounded over with an 1/8" round over bit. Then the individual louvers were cut to length. Next the tenons were cut with the SS dado set.

I don't know about the video other than I can easily play it on my IPAD and since Apple doesn't allow flash on IPad I suspect the problem is something else.

I got the link for the video from a highland wood worker email. Apparently highland woodworker and fine wood working are joining forces to produce their videos.

John that must have taken days and days to do.

Yes my system was blocking it(both scripts and adblocker) and now that I've unblocked and have scripts turned on it I still can't see it because it is a adobe flash video which I have turned off due to all the problems they have had. I'm loosing interest in seeing it so I guess I'll skip it. All this protection gets old. Well I guess HTML5 will at some point get implemented and get rid of some of these issues.

Not sure how the apple thing works but I'm seeing an attempt at flash video.

Yes it did.

The most interesting thing of the video was they honed the inside of the chisel. I don,'t mean they sharpened it, which they did using a cone grinder but after they finished sharpening they honed the inside using sand paper wrapped around a dowel.
They said it made the chips eject easier thus making the cutting of the mortises much easier.
