Spoil board cutter?

[mafitch7479]

Does anyone have any recommendations on a spoil board cutter for surfacing the MDF spoil board on our AXYZ router? I would think it'd have to be pretty balanced, since the default spoil board surfacing program won't run at any less than 8000 RPM's. I've seen a couple of different models from Onsrud, and one from vortex tool, I'm just not sure what to go for.

Thanks in advance.

i use a standard 1.25 inch mortise bit,

If you don't mind spending the money, I'd get either the Vortex or the Amana. I'll have to check, but I think we have the Vortex at work. It's about 3" diameter, and we run it at 15,000 and 600ipm. Still takes 5 minutes to surface our 5x12 spoilboard.

I use an onsrud 1.25" 91-000 P84492. Surfacing the spoilboard makes the most dust you will ever see from your router

We ordered the vortex yesterday afternoon, so hopefully it'll work. The tool rep we go through didn't think it was a good idea to run it at a very high RPM, but he's got less experience with routers than I do lol.

I believe it, especially since we mostly cut aluminum, but we have a dust collector that I can strap onto the spindle head to keep the dust down.

I just ordered a Onsrud 91-000.
I see 18K max RPM .125" Max cut
What overlap or machining strategy do you use?
I can just imagine the amount of dust it generated. It will be a good test of my Kent dust shoe and Oneida Mini Gorilla ;-)

Thanks

I think I just overlapped it by like 15% of the cutter diameter. I've only had need to do it once, and that was apparently in May, so it's been a while. Our router has a program right in it for planing the spoilboard.

As for the dust, it wasn't bad. Our dust collector worked very well. I think it's an Oneida Gorilla, 3HP if I'm not mistaken. Wasn't a bit of dust that escaped.

Thanks,
I will have to either use Mach Wizard or VCarve to write a simple program.
My dust collector is the little brother to yours. Only 1.5hp. I will be using a short hose. ;-)
I would have guessed a larger overlap.
Good thing I asked.
Thank you.

I didn't see much reason to have a very big overlap, depending on how much of a cut you're taking of course. I only took like 0.025" off the top of the board, so it wasn't much. And our dust collector piping must be close to 30 feet long to the router, plus 10-15 feet of flexible hose to run to the spindle. It's a pretty slick setup. Just wish I could quiet down that damn noisy vacuum pump!

I think I have about 0.045" to take off. I will probably take it in two passes to understand how badly my table is sagging. I ran a dial around it yesterday and I think I have a 0.040" dip in the middle. I eventually will add another support under the table.

I am not running Vacuum yet. I have a small pump that I might try out after I make a vacuum table. Mine is not an industrial router like yours is. Mine a little hobby one.

I assume you are using a big pump and are just sucking thru the MDF?

Thanks

yup, pull right through the MDF. Works really well except when trying to hold down relatively small pieces.

How big is your router table?
How big is the pump?
