Sorry but too late to help you, what's done is done and all that...
For others coming along, you DON'T NEED TO BUY a fancy template to rout out an opening for your plate or lift. All you need are four relatively straight sticks, some clamps, plastic wrap, a short top-bearing flush trim bit(which you need anyway foir the template) and some Bondo.
Here's the procedure(nothing new, Google is your friend): First, clamp one of the sticks parallel to one side of the table wherever you want your plate to sit. Front, back, side it makes no difference. Set your plate or lift down on the table against that piece wherever you want it to live, centered, offset, whatever.
Now clamp the other three pieces around it, tight to the plate. Before you start routing check your flush trim bit with a caliper, if the bearing is wider than the bit, add a piece of blue tape or two to the plate to match half the difference. Add another layer so the opening you rout will be ever so slightly larger.
Next step is to check the radius on the corners of the plate. If you have a short flush-trim bit that matches you're good to go. Chances are you don't, lift and plate manufacturers seem to pick corner radiuses out of their [email protected]
, sorry, hip pockets...
Now the plastic wrap and Bondo come into play: rip off some wrap and stretch it over the corners of the plate so the Bondo won't stick to it. Mix up a little of the Bondo, it won't take much, set the plate down between your sticks and pack the Bondo into the corners between your sticks and the plate. Don't let it get up higher than your plate.
After it's cured, yank the plate, use the sticks and the Bondo and the sticks as a template for your flush-trim bit and rout your opening to depth. Easy-peasy... It took longer to write this reply than to do it.
A small can of Bondo from your local auto parts store will cost you $5-10 and you'll have a lot left over when you're done for more patterns(use your imagination). We all have sticks laying around and plastic wrap.
You buy a fancy template, it's only good for one particular plate. How many of those plates are you going to use? How many table tops are you going to rout for that plate? Maybe you decide to buy another plate, are you going to spend the money for another template? How many templates do you want hanging around your shop taking up space just in case you decide to make a new table for that particular plate?
Save yourself some money and have a little fun, isn't this what it's all about?
