I made this new fence to replace the original Rockler fence. It wasn’t tall enough to use the coping sled that I built.
My design was based on several pictures of fences I saw. I had these HDPE pieces that were about 4” wide and 1” thick. I found out that it is easily planed, jointed and cut. The lower pieces slide in and out. The top piece is fixed. Overall it is 8” tall and 32” wide. I initially planned to use melamine, but didn’t like how it looked. Then I thought about laminating some mdf, but could only get laminate that looked like stone. Finally I thought about the HDPE and I’m glad I did.

Really nice job on that fence, it’s inspiring, makes me want to re-do mine. Thanks for sharing this one.

That’s a cool idea Bill and well done….I’m curious about the stability of the HDPE. I had some thinner stuff, 3/8” I think and it warped while sitting on the shelf. Not sure though?? Good to know you can plane it!

Nice fence Bill. That should last awhile and stay smooth.

Thanks guys. Jeff, in 16” the pieces had about 1/32” bow. I jointed that out and planed them flat. I feel. It will stay that way being bolted on.

Stellar job on building the fence….It looks like class A work….It works on the same principal as my fence on my router table…I like the sliding fences, and the ability to open them as needed for the size of the router bit you’re using…..Also, they act as a safety feature…..Good job, and they will last as long as your router table does…..

Nice work, had no idea you could plane it. Not that I really enjoy all that racket the planer makes… LOL

Looks nice and solid but I too am worried about warping of the HDPE I got a 3’ piece from LV and it was warped but hope fully with it bolted down it will stay straight .What are the two slots in the opening for ?

It does look nice and solid in fact it resembles the bumper off a fire truck (tee hee)

I have a few chunks I scavenged from the rubbish, and I need to do some thicknessing so I will see how it goes.

I’d bet the slots are for mounting featherboards to hold down work. I have some similar in mine and that’s what I put them there for.

Thanks all.
The slots are to mount a bit guard above the bit. I sometimes use the guard as a hold down. I guess I could also mount a feather board too. My old fence had the slot the whole length, but I only wanted it above the bit.

Now that you say that Robert, it does look like a bumper…...totally unintended. Lol.
If the plastic warps, I can just take it off and go back to my original idea of laminated mdf.
