Our shop is plumbed for our compressors and we used a suction tank to drain the oil from boat motors. I was looking at our suction tank and then at the harbor freight website and this. Will it work for stabilizing if I take the pump out and just use it? or is it not enough suction?

My opinion my be skewed due to being a heavy duty refrigeration tech for most my life. But if I was stablizing I wouldnt bother with that. Again I have no experience in stablizing but understand the process. I would at a minimum use the 2.5cfm single stage on bottom of same screen as your link... that would be a minimum.
However I have several robinair two stage vacuum pumps which would work better.

Depending on what your doing...... a few blanks as a hobby as needed then go with a lesser value pump.

If your going to be doing blanks weekly/daily then I would get a 2 stage pump.
 
There is a tutorial with that used on a vac/pressure pot.( it is removed from the plastic can. As been said you will have to keep it running air into it to keep the vacuum High/low take your pick.
Depending on where you are located in relation to sea level and other mechanical considerations IE leaks in the system.

You would have to run the compressor continuously to get anywhere close to enough vacuum. Try it if you don't care about ruining the compressor. The little 2.5CFM for $79.99 would be better.

Saw this on ebay earlier. I have no knowledge of vacuum so I don't know if it'd be any good or not: Vacuum Veneer Thomas Pump 2660 Vacuum / Compressor 3-4CFM 24"VAC | eBay

I believe this is the same one Itzapen has and it seems to be a good one.

Now I am confused. Why would it have to run constantly? I hooked our oil canister up to the compressor. Started the suction and ran it up to almost the red line and closed the valves. It held that level of vacuum until I opened one of the valves. No compressor needed after that

Can't I place a valve on the suction hose and seal it once it reaches the desired level of suction in the canister?

I am thinking I do not understand this.

Because the blank/s will continue to degass for most likely over an hour as you pull the air out of it. Thus you will loose some of your vacuum, not all of it.
 
Even this confuses me.

would it be enough to cause an issue. I mean, is it so much gas that it would cause the vacuum to decrease that much? Yeah I know I should just shut up and do it the tried and true way but I am trying to learn here.
 
If you want one of those HF venturi type vacuum pumps, I have one new in the box that I'll sell cheap or trade for something.
 
I use a pickle jar, and this vacuum pump.

Brake Bleeder & Brake Bleeder Vacuum Pump Kit

I pump it up as much as possible, then check it periodically over the next couple hours to make sure the vacuum hasn't declined. Then I leave it for two to three weeks in a solution of Mineral spirits, and polyurethane.

After the couple three weeks, I put in the toaster oven.

I get complete saturation, and turning the blanks is pretty smooth.

I know it isn't the fastest system, but I'm not so short of blanks that I can't wait for the process. I even once borrowed a friends vacuum pump, and didn't even use it.
 
So, it is not that complicated. I'm going to give this a try and see what happens.

Penguin I don't have anything to trade. How much do you want for it?

I think the problem with that will be if you stop the vacuum you stop the removal of air. When I stabilize I run it until the bubbles stop and then about 15 mins after to be sure I got it all. If I reach -28hg and turn it off I stop removing air. I get bubble for a while @ -28hg. So with this set up your Compressor will have to run the entire time to maintain that vacuum. I have had some blanks take up to an hour to get all the air out so more or less your Compressor will also need to run for an hour straight which in reality it is not built for.
