Waldo's coping sled

**Waldo** · 27th June 2008, 10:21 PM

G'day,

This is my first time, I'm no longer a vergin (changed spelling so as not to bring Forum into disripute - and I couldn't think of another meaning for the word) I did it, I finally made a jig for my router table.

I'd been looking at the Infinity coping sled, for a short while I thought about buying one, but then I figured I could make one. I already had a few bits from when I made my r/table, namely the Incra Mitre Slider 450mm, which I had bought in preparation of making a different jig altogether.

My first thought was what material to make the sled base from. I thought about aluminium plate, but it'd be pricey and I wanted a decent size, so I went shopping for a plastic chopping board. It had to be perfectly true on all axis, so there I was in a House shop, pulling out all the chopping boards and looking at them individually. Finally I found one 450mm x 295mm x about 15mm.

So after near a whole day today carefully measuring and tapping all holes with a M5 tap I finally had it near finished. Near finished, because I now have to work out if I put in a sliding fence to clamp on the left side of the stock. I'm not sure if it needs one, if I do (see pic 3) I'll route two slots on the underneath where I've roughly marked in blue, with the toggle clamp roughly where it is now.

I did forget one thing, to drill two access holes for a the track adjustment. I can easily do that tomorrow. (that's also the reason that the track runs out from underneath the sled to the right, the one of the adjustment holes falls a bout 5mm to the right of the acylic, to the other side by about 5mm is one of the fastening points into the track)

Jig for holding stock while I cut rail and stiles.

Or as the Yanks call it, cope and stick, which is why it is called a coping sled

Looking good Waldo

In a panelled door, the stiles are the outer vertical pieces, the rails are the horizontal pieces that connect to them to make the perimeter of the door. In a panelled door there will always be two stiles, but there can be more than two rails, because another rail (or rails) can be used to divide the door horizontally (symmetrically or not).

Older doors had a central stile also, making a four-panel door typical of the Victorian era, usually with a deeper central and lower rail than the top rail.

Rails and stiles are structural parts of a door, joined by mortice and tenon or cope and stick joints (or even, in small cabinets, with biscuits or pocket-hole screws). They should not be confused with glazing bars, etc. HTH

Nice jig, Waldo!

Ray.

Looks good.

Will you have a tear board attached ? will need one for coping rails I would have thought.

thinking just some piece of scrap that you screw to the fence to take the blast out. Maybe drill a couple of holes in the acrylic there to pull the scrap tight to it with screws.

just a suggestion. Any cross grain cut will need it. reminds me of the old machine at work. tenoning machine that works on the same principle. but its for door rails.

Gday Jake,

there'll be a sacrfial board for tear out, just hadn't got that far yet.

Well, you got me! I thought it was a bit odd, but I did what I usually do - jumped right in!

Lovely Red colour.

It looks pretty good with solid clamps.

I have made a couple out of ply when I was making panels. None of them keepers though.

So far I haven't been able to convince myself to put a Mitre slot in the router table. You have nearly convinced me with that flash sled.

The sandpaper sounds like a good idea as you get a fair bit of kick when routing the ends of rails.

**Waldo** · 28th June 2008, 11:21 PM

Scally, with the number of frame and panels I'm about to do I thought it a good investment so far as the cost involved, and I still came out ahead of the cost of the Infinity. Yeah, the red looks good, it's meant to make it go faster. ( it was red, yellow, white or blue as in colour choices - red won)

All the commercial sleds i looked at didn't have a mitre slider, but i thought it'd keep it square to the bit more so than relying on my pressure in keeping it against the fence.

He often goes fishing, I bit a little but didn't let him catch me.

Nice one Waldo

Would you consider adding the Lexan type fence runner at a later time? From the original pix it appears that it could be a good idea to keep the chips out of your face as well as acting as a helper for your chip/dust extraction. Could also be an aid for the runner under the sled as it would then be bearing on 2 surfaces.

Just a thought,
Bob
