That jig idea but using a rub collar as opposed to bumping the base against fence walls would lock in the exact thickness of various widths of stock.

Paul, the router base IS the guide bushing with this jig. It's dimensions do not change. This jig will also allow you to accurately cut a board to thickness like with a planer. It just takes a lot longer.

Where are you finding the 1/2" MDF. I 'm in No. Calif. Within 20 miles of Lowes, Home Depot, and several lumber yards. All I find is 5/8 or 3/4.

Thanks, Rusty

Bj,

I got my brass template guides yesterday from Pricecutter(including a 1" O.D.). Right away I built a modified version of your dado jig. I modified it because I dont have a 1" bit or 1/2" MDF. So I cut down 2 planks of left over laminate flooring using 1/2" plywood on the ends and the new 1" guide for the spacing. Works great. I,ve allready used it to route a stopped dado in the surface of my new table. So I could add T-track(not miter track) for feather boards or whatever else I may need. Would post pics but I'm having trouble with my camera.

Thanks Rusty

I found it at my local HD on the east coast but only in 2x4' sheets, not 4x8. This is better for me as it is easier to transport. They also have 1/4" mdf.

Hi Rusty

I also get the MDF stock from H.D. like Michael, in comes in 1/8",1/4",1/2",5/8",3/4",1" and with luck 1 1/4" but it's hard to get the full 4' x 8' in the all sizes, like Michael I look in the precut bin for what I want or need I also get it from a sign supply company they carrier the full 4 x 8 in stock for sign painters, it's a bit higher in price but it's 4 x 8 when I need to use a full one.
I like the MDF stock it can be used in so many ways because you don't need to worry about the grain directions and you and I can used it all up for so many projects unlike the normal wood boards we get from trees.

Like you I have started to use laminate flooring in some of my projects it's flat ,it comes prefinished,and strong for it's size, and smoooooooth .

Brass Guides, I got the bug from Bob and Rick (RWS) when I saw all the items they made using brasss guides and templets , it's easy to make one of anything but to make a pair or make two or more of the same that's the hard part when it comes to using the router or any other machine but the brass guides take care of that one easy.

Tally , just made some fishing lures that blew me away with some help of the members of this fourm he did a great job using the brass guides and a jig, I didn't think you could do that with router but it just goes to show you and I how versatile the router is when we use the guides.

Rusty, go to a local plywood wholesale house. They will have the 1/2" MDF however they will not sell it directly to you but get them to call one of their dealers close by so they will sell it to them and you pay the dealer. In most cases that I have found they will go ahead and make the deal there.

Dewy

Regarding 3/4" plywood being thinner, the world has gone metric and plywood imported from other countries comes in 6, 9, 12, 15 & 18mm each of which is thinner than 1/4", 3/8", 1/2", 5/8" & 3/4"
3/4" is 19.05mm so the plywood is 1.05mm thinner, approx 40thou.
UK started with metric 35 years ago but many still prefer imperial measurements.
Very few 30 year olds have ever known inches as all they were taught at school was metric.
Because most routers still come with 1/4" or 1/2" collets we can use bits made for inch as well as metric.
To cut dados for 18mm sheet material I have an 18mm cutter.
It can often be confusing having both metric and inch sizes but I often find it helpfull such as when cutting a 1/2" mortice and starting with a 12mm bit then cut to finish size with a 1/2" (12.7mm) cutter.

Here are some Dado Jigs that will accommodate any thickness of sheet stock & make doing dados a snap.
One is a manufactured jig from WoodLine USA called the DadoWiz & two you can make your self from ShopNotes & WoodSmith magazine.

DadoWiz

The best one is in ShopNotes issue 76

You can check out a video of this jig in action with this link.
Look near the bottom of the page

Hope these help

I just bought the DadoWiz but have not used it yet but it was featured in a wood magazine a few months back not sure witch one at this point but may be able to find it if some one needed to see the article.

I still plan to make the one in ShopNotes issue 76

Dan,

Those plans look prety good. But they both trap the routers sub base which is not allways true. BJ's jig has a 1" wide slot to accept a 1" template guide. All you do is center the jig over the center of the needed dado. If you need it wider than the largest bit that fits thru the guide just move it over and reclamp after the first pass.

It's quick and easy to build. And I have used it several times since builing it.
