Default Inserts necessary?

Hi All,
Iím new here. Thanks in advance for all of the time and input. Iíve read a lot of older posts (great stuff, btw) and while there similar things asked, I didnít see anything on this exact issue.I wanted to join and ask some questions about a router table that Iíve been designing in my head for some time now. Right now, Iím trying to understand the real purpose of the inserts that go into the plate. Hereís why I askÖ

Iím designing my customer table and top to fit my needs. I bought a Freud FT3000 VCE to be my full-time dedicated table router (I have other routers for other jobs). While Iíve been designing, Iíve spent a good amount of time reading on router plates from the usual retail outlets. For this particular router, it looks like I will need to buy a blank and drill my own holes. No big deal. But, as Iíve thought about this, I canít stop thinking about using an alternative plate. In fact, Iíve got a metal fabrication company around the corner and they take walk in jobs (it is actually quite a large company; I trust them to do good work). I was considering taking in a plate design and having it milled to my specs. Then, attaching my router directly to the plate WITHOUT the inserts (I would not even have them mill out space for the inserts - ).

What I am I missing here? Iíve got to be missing something as to why the ďinsertsĒ are so important. I should be able to still change the bits from the bottom. Will my idea of fabricating my own plate without a spot for the inserts work?

Hi Buzz - Welcome to the forum
Congrats on the 3000, nice router and I really like mine.

The reason for inserts is primarily safety. Work support around the bit is important to keep the bit from grabbing the workpiece and throwing it at something. Now, that big Freud will spin 3"+ bits very nicely and you want the hole in the plate to accomodate the largest bit you are likely to use. So far so good until you need to use a 1/2" bit, suddenly there is a whole lot of hole the workpiece has to travel over with a chunk of sharp carbide whizzing around in the middle of it. Especially disconcerting if the workpiece is relatively small to begin with. True, you can just go with a smaller hole but if, at some point, you want a larger bit, you are back to making another plate.

Personally I'm a big proponent of inserts. So much so I bought the INCRA plate for the Freud plus all the insert plate sizes they make. I just feel more comfortable when there is almost no gap around the bit. JMHO

The problem with experience is I usually get it immediately after I need it.

Hi Buzz,
+1 with John. I use different sized bits in my tables & like to have inserts that fill the gap. If you machine your plate to fit the larger bits such as a raised panel bit (up to 3-1/2" dia.) that would be fine as long as that's all you use it for. I wouldn't want to run a smaller bit or a small part to be machined over that same hole. That would leave too much opportunity for a damaged part or an injury. Maybe the machine shop could machine a little recess so you could add & change inserts.

Have a nice & safe day!

Buzz, I feel you are trying to reinvent the wheel on this. As mentioned inserts give you the ability to use guide bushings, reducer bushings for safety and still be able to use large bits. Save a bunch of time and money and buy a decent quality mounting plate; phenolic plates work just fine.

Machine shop Rate? I really doubt that a plate machined to your specs will cost less than a good aluminum plate with inserts bought online. I've seen undrilled plates with inserts around 65.00 USD I'm chicken and pay 100 for a drilled plate. My rule of thumb is I always screw up so I must save 50% so when I screw up and buy 2nd plate I am even

What everyone else said +1, except I prefer aluminum plates over phenolic.
