edging a board for glue up
I have some 1.75 boards to glue together, Is there a way I can edge joint these boards?
Im thinking that maybe using a straight bit, and then moveing the gantry from one end of the Y axis to the other to make sure the gantry is perpindicular to the board...Any advice on this?
Thanks

Re: edging a board for glue up
If you flipped the board when gluing up so that any angle on the edges cancelled out it would probably work but an edge jointer or just a long hand plane would probably be just as quick. You've got bit deflection, material lining up, gantry plumb etc etc to worry about on the CNC.

Thanks for the reply.
My problem is the wood can be too heavy to run through the jointer, plus I don't have a jointer hand plane.
What if instead of trying to edge the board we plunge down about 1/8" per pass,
and take 1/4" or so off the edge of the board.
as far as making sure the board is at 90 degrees of the gantry..
jog the gantry from one end to the other to check
Just a thought...

Re: edging a board for glue up
A jig would probably be more accurate than a jog . Secure some ply/mdf to the deck, then cut through in a straight line parallel to the gantry movement. All subsequent passes will be parallel to this edge.as far as making sure the board is at 90 degrees of the gantry..

Ideally this piece would self-locate onto your deck to auto-align it the next time, and it would have some clamping mechanism to hold the work leaving the edge open.

Re: edging a board for glue up
Don't know exacly what you have in mind but from my experience, people tend to overthink when prepping boards for glueup.
If you've got good flat edges, good glue and some clamps usually that is all that you need.
[Depending on species, some of the more oily/waxy woods do require prep to bond].
One concession I do make is using a glue line rip blade on pieces I plan to glue. Other than that, I've never had a failure doing glueups with very minimal prep.

Once we got our table saw tuned in the edges were suitable for doing glue-ups.

Re: edging a board for glue up
I do have a glue up rip blade for my table saw, but its no good if you have a barked edge against the saw fence.
I also have a track saw, but i get a bit of chip out from my 16 tooth blade.
I dealy I would like to flatten the 2 boards at the same time, aprox size 20" x 72" x 2"
then edge the 2 edges with the 2nd toolpath.

Re: edging a board for glue up
Barked edge I'd rip with a bandsaw, fine tune with sander and send it to the table saw once true.
I know guys that have no problem freehanding on a table saw, I consider that hazardous so take extra steps to avoid that.

Re: edging a board for glue up
Put the two boards next to each other closer that the size end mill you are going to use and joint them both at the same time. Then, as Adrian mentioned, flip one of them over and any deviations in vertical should cancel each other out. You could flatten at the same time...joe

This is an OLD OLD Izzy Swan video using a home made jig to joint lumber. It's old, but it works very well...
