This is an amazing machine for its time. Europeans and Asians saw the value of small machines before US. The Stik Clam has a few weaknesses that can be compensated for if you know ahead of time what will fail and why. Modern CADD can "test" the weaknesses before even making a part. The basic concept of the Stik Clam has not been improved by a lot. The backhoe configuration has some advantages but fails to be able to do a few things that the Stik Clam can do, and vice/versa.
What a machine is worth is determined by 1.) what an owner is willing to sell for AND 2.) what someone is willing to pay. If an owner will not sell at any price, it cannot be bought. Sometimes that person can be induced to sell if offered enough, and if the person buying convinces the owner it will be cared for and appreciated. If you have to spend a LOT of money and effort to restore something the value to sell will be FAR LESS than what has been invested, even at a fairly high sales price.
I am located at Helenville, WI, not interested in selling, but willing to help in any way anyone that is restoring their own Stik Clam. Also interested in seeing other people's machines.
