Using 80/20 for an adjustable router planner Jig
« on: December 29, 2017, 01:53 AM »
I need to plane down large slabs and I think I want to build myself an adjustble router planner jig using my of1400.
There are lots of ideas online using plywood or mdf but I'm wondering if anyone has tried making an adjustble one using 80/20?
When I say adjustble I mean it will accommodate various widths and thickness of wood slabs

Thanks

I would think that 80-20 would be too flexible (in terms of deflection).  I prefer to use a really rigid (and heavy) setup of Douglas fir beams along with a sled made of phenolic-covered Baltic birch plywood.  My setup has all the size-related flexibility that I have needed so far and can legitimately foresee for the future.

I used two 96" 8020 1530 extrusions to make a planning jig. These extrusions are used extensively in manufacturing setups and CNC builds.  273036-0273038-1

That's a really interesting setup.  I can see how you get the rigidity.  I'm curious - how do you support the MFS profiles?

80/20 makes extrusions up to 80x120mm so it can be more than stiff enough. The site has link to an interactive deflection calculator so you can determine what is stiff enough.

8020 has a UHMW profile that they market for bifold door applications.  I used two 12" lengths screwed to two 2x2" aluminum angles.  I generally made my jigs as simple as possible, so the MFS jig is just clamped to the angle.  I used my MFS setup and 1400 for this setup, but have since bought a 2 3/8" planing bit and plan to use my 2200 next time just to speed things up.  I won't be able to use the MFS sled due to the size limits of the pattern collet.

Nice setup, how do you attach the MFS to the 80/20?

Is there a bearing carriage that I can't see?

This extrusion slips into the side groove of the 1530 and has a 1.5" face where the aluminum is screwed.273040-0

Thanks...gotcha. The 2x2 angle is the full length of the UHMW profile.

I like it because it easily breaks down into just several small pieces to store.

Really clever!  Thanks for sharing your setup.   [smile]

Nice design. I'll file this one away for a future build.

Very nice, I love it. Would it be ok to get a parts list for the items that hold up the MFS? ? I'm going to place an order.
Very nice and simple setup, exactly what I was looking for

The Poplar Shop made one and he has a video of it on his Instagram page.

I based my planing sled on Nick Offerman's design as seen in a back issue of Fine Woodworking.

FYI

openbuildspartstore.com has a sale going on until Feb 4th. Most parts are discounted but they're also offering free shipping which is often a deal breaker when it comes to ordering all these aluminum extrusions...

Just note they're smaller metric sizes 20 mm compared to the 1.5" (1500 series 80/20) though they do offer 40mm x 40mm. One benefit to Openbuilds is the v groove track which appeals to anyone looking to add motion to their builds, such as a router sled. Think they're products are a good fit for this application unless you need the increased strength offered in 80/20 extrusions.
