...drilling aluminum should be easy for every machine.
I don't know about that one. If I put a dial indicator on router and push on it with my finger, it only takes a couple pounds of force to get .010" of deflection. The deflection causes the angle and position of the spindle to change relative to the table, which puts a lot of bad mojo into a drill bit that's spinning 15-30k rpm. A big part of the problem is the plastic mounting bracket for the spindle, but there is still a fair amount of deflection in the frame itself. It's a router table, not a vertical machining center.

However, my fear of the twisty frame and bogging router rpms has caused me to lower my feed rates too much. On the last cut the bit was getting gummed up, presumably because the chips are getting melty. Speeding the feed back up actually made it cut better. When I get some free time, I'll put another piece of aluminum on there and let'er eat, but I'm fairly sure it will just snap the bit.

I have had drill bits deflect about 3degrees without breaking (when drilling into an angle with no spot drill) tooling makes a difference. As for milling with a router table what I had found useful in routers and milling centers is setting up an air blast that point directly on the milling or drill bit to clear the chips. When machining on unstable work pieces or machines of will greatly benefit the job. Worst thing for tool life is double cutting chips and starts to bind in the flutes ( melty chips). Since you can't use a flood coolant on your router use air. A air gun from a compressor would work if you wanted to hold it. Also get coated end mills the will help tremendously with chips not clogging the flutes up.

I'm guessing it goes for $75,000

That looks so good

Finally took some pictures of the test fixture that I built for work. Too bad my phone was being a potato.
It's for testing a 6-up array of LED lighting boards. It's a basic functional test; just put 12v on it and make sure it lights up. Previously we were manually sticking meter leads in the connector on each board while holding a welding face mask over it so you didn't get blinded. This should be an improvement.

So I bought an '04 Sienna van with a bad transmission. It had been power flushed and that caused a plugged filter about 1000 miles later. It was a good price due to being broken. I towed it home and changed the filter and fluid, that got rid of the cavitating pump noise and it drives but the shifting is poor, harsh 1-2, weak 2-3, then 3-4-5 works ok.
Last night I pulled the valve body to disassemble and clean it, I am going to try that first, if it still doesn't work I'm not out anything. Most likely I will be hunting for a U151F transmission.
I didn't get any pictures because my phone died but yikes there are a lot of small passages and valves in the valve body. It's like black magic going on in there, several spools seemed sticky so I have a small amount of hope that it might solve my problems to clean it all carefully.
