« Part 17: Still working on the sled.........some progress........ Part 18 of Alaska Jim's Comments of the Day series Part 19: A new LJ Mentored Project......Integrating my old saw and the Super Sled into the Shop »

Yesterday and today I got the little front fence installed, the push handle-blade bury block assembly constructed and installed, and the fence calibrated.

I am now ready to use it to make my quick and dirty temporary router table modifications, and then make the miter arms. Need the router table fixed to do that. First a couple of pictures, to make the explanation easier….......

..........sled from the back…......

........sled from the front, the operating position…....

So let me digress.

I know I should have taken a picture of this, I blew it…......

If you notice, instead of a closet rod for the handle as I initially planned, serendipity intervened and as I hunted for the piece of closet rod I had somewhere, I stumbled upon this piece of railing for a stairway.

Perfect. Better than the rod. So I pulled out my Oshlun 8 inch bargain dado set, used only once before on some ZCI’s, and dialed iin a very tight fit for the vertical piece of plywood, and eyeballed the center, it turned out to be adequate, and pushed it through with 2 pushblocks. Looked at the dado.

This is hard to believe, I had only used it on MDF before with good results, but that was not a good test. Not only was this dado perfectly square, but all surfaces actually looked like they had been polished. If there is a better dado set out there, it must be that you can see your reflection in the bottom of the dado. There is nothing I could do to those surfaces to make them better, and this was a low priced bargain dado set. Wow. Bought this on the advice of a LJ review. Read them reviews, gals and guys.

So back to the story…...........

So I did the glue up for the handle support and bury block, rounded and sanded it because it sticks out a little from the back, and will easily get damaged, and I will brush up against it.

I am finishing everything with clear Watco, but I used a little medium walnut on the handle. I attached the handle-buryblock assembly with two lag bolts into the fence, no glue. I thought of four, but it is pushed against the base, so even as the fence gets cut higher, it will still help to hold it together because there is no motion possible in the up down direction…......just speaking of forces of course. So except for the rails, no glue anywhere, on purpose for maintenance. But of course, then my fasteners have to be robust, and they are.

Here is a little more detail of the handle assembly…...

OK, now to the calibration. I had actually done a quick and dirty calibration yesterday, you know, make a cut and flip it over and compare, that’s how I did the initial calibration, after making the initial kerf.

So I get out my 6 inch try square, use it all the time, I should put a ring in my nose to hang it from.......

by the way the measurement tote is used literally constantly…..and start putting lines where the fence is now…....

What is this?, the fence is off angle in the verticle.

D——. I already jointed this thing. Get the jointer back out, easy deal, recheck the jointer for everything, reread the internet explanations of how to use a jointer. And did this and that, and figured out I moved too fast. Moved real slow, perfect right angle. Whew. Neophyte in action.

Put the fence back on. Do a 5 cut test. Off 0.003 to 0.004. Adjusted…redid the 5 cut….and got just about 0.001…....not worth changing. By the way, all this stuff about alignment comes from LJ’s.

So now my sled is functional. I can use hold-downs and even do 2 foot rips. All that is left is to install the stop block T-track, and make the miter arms. But that will wait for the router table quick and dirty mods, and then on to my utility computer cart for the office….......that started this whole venture into hobbyist woodworking.

My next blog item is some philosophy, and this blog got so long, decided to make two entries….......

Missed you in the list, but I haven’t forgotten. So many people have helped, makes it a lot of fun.

Hope you are doing well….....

This looks really good, Jim. I am sure John Nixon would give it his seal of approval. :)

Using the railing was a good idea too, by the way. Just another reason to not throw any scrap piece of wood away since invariably we will find a use for it down the road.

Thanks for the comments. That piece of railing, it was about 12 inches long, I almost threw it out a dozen times. You just never know. I am trying to make it look a lot like your sled. Appreciate the comments and your blogs that inspired me….........

Great Jim! I see you found some good plywood to use, looks like a super addition to the shop.

Yes, I found one piece of decent plywood. I am chewing up that old plywood pretty fast at this and that. The base of this thing had to be level, though, so I had to be choosey. Still have to make the miter arms, but that comes after a quick temporary router tabel fix.

Dick
Miter arms left, and the T track on top of the fence, and a stop block or two. I already used that T-track in the base for a holddown point. Thanks for following.

Jim:

I shall now delete all pictures of, and references to, my crosscut sleds.

Expect a call from the good people at Webster’s. They’re going to need pictures, to update their newest dictionary entry.

That, Good Sir, is functional furniture. I don’t know HOW I would do it, but I would use it for rips, too, if I could.

Yours is a textbook example of that famous Abe Lincoln story: Mr. Lincoln, if you had eight hours to cut down a stand of trees, how would you proceed? Mr. Lincoln: I’d spend seven hours sharpening the saw.

For an OCD guy, you don’t have ADD. You sat back, did your homework, consulted your ‘experts,’ and built a sled that anticipated potential pitfalls, finding ways to avoid them.

It’s cool. It’s racy. It’s elegant. It’s great!

Curiosity, though: are you going to put a (lexan or other) windshield atop that bad boy?

Also, it may be worth your while to consult a structural or marine engineer. I’m guessing that transom will support a 5HP Briggs & Stratton outboard, but … no harm in knowing for sure :-)

Neil and Dennis

Just back from the opthalmologist and still have blurry eyes. Neil, I don’t know how you do this, I feel for you.

So first, if you look carefully, you will see verticle grooves (dados) in both fences near the saw kerf. I think I will use a MickyD style guard, a three sided 3/16 inch Lucite Tough guard. This hinges, however, on dust collection. And it is also about guards and splitters. And it is related to dust collection when the sled isn’t used.

And I will now give you a verbal sneak preview…...go make some popcorn…....this is a long preview (-:

I have made it a blog entry, here is the link….....

The sled looks great Jim and I really like that handle. It is elegant and looks comfortable to use. Congratulations on the successful sea trials and necessary corrections. This sled will need a magnificent name. Have you thought of one yet?

Thanks for the handle comments. If I had found my original closet rod piece, it would have never happened. But I found this old piece of railing first, I believe it is about 25 years old, (never throw away a piece of wood), and I instantly recognized it as the solution. And it is absolutely comfortable and appropriate. In fact, since it is designed as a hand hold, it would make sense. Serendipidy, not planning got me that one.

It had never crossed my mind to name it. I’ll have to work on this. My benchtop downdraft table, the one with the interchangeable top panels, either with or without holes, is called Dusty. Really original…..(-: And by the way he is in heavy use.

Ok. I will work on this name thing. By the way, the sled has a bunch of stuff to still go on it…...I finally dreamed up my sled travel limiter as I drove home from work tonight. Figured out a simple solution. It is the item that prevents the sled from moving forward more than is necessary, meaning when the middle of the blade is at the back fence. I may make that tomorrow, it will be simple and fun, and make a good blog item. There are certain features I wanted it to have, and I solved the issue simply.
