Try soaking it in Kroil. Probably not available locally so order it online. I have had it free up things that Blaster, Liquid wrench, etc. would not budge. Good luck.

Here's R2D2 bought at a liquidation auction of a local industry. It had a minor problem and must have been pushed off in a corner and forgotten for 40 years or so. Great DC welder. I love it.
I guess the photo didn't make it. I will try to figure it out.
While we are deeply involved in complex ideas here today, let me throw in my favorite from Robert Frost:
Take care to sell your horse before he dies, The art of life is passing losses on.
Take a look at the foundation plans for the large Little Giants in their web site. I used a belting from Texas Belting and Mill Supply in Houston for a pad under my 100 lb LG. Holding up well for a couple of years. Good luck.
I agree with hauling it upright and securing the top of it to the 4 corners of the trailer. Also, invest in 4 more straps and tie the base to the same 4 corners. I have had the base walk while the top was held in place. Arrived much like the leaning tower of Pisa.
There is another interesting event coming up on Oct. 21-22 in Branson, MO. It is a swap meet for antique machinery and this year is adding blacksmiths combining with the Blacksmiths Assoc of MO. I went last year and it was a good event. See details at owammos.com.
I have two small flypresses for sale posted in the Houston Area Blacksmiths Assoc. website www.habairon.org. I am in Bellville, TX. You are not too far from me. Tommy 979-830-3578.
