Put a scissor jack under the table and use a drill with socket adapter to raise and lower it. I found some cheap chucks on ebay to replace the ones on an old Milwaukee 1/2" and a B&D old metal bodied 1/2" single speed non reversible (one of the good ones they used to make). Both were given to me with broken chucks. The most expensive replacement was between $12 and $15. One I think was only about $8. Both have worked very well and for the last 5 years or so. You can spend a lot of money on one but it doesn't mean you need to. Some of the chucks I looked at on ebay were about $1000.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
