These No. 4, 5 ,6 plus the vercipower can hog metal. They can do a 1/2 inch cut in some situations no problem, I am on a No. 4 right now that came out of the Navy supplies. This machine still has it scrap marks on it. It is a 1979 make. They crash it over a year ago. I have never seen a cross screw look like a snake. The cross screw bracket was broke off. Ended up cutting out the screw. Some one took a stab at fixing it. The The feedbox was out.The bearing retiner on the cross screw was cut open. The trouble I had was fitting the new parts ( cross screw, cross screw bracket, two blacklash nuts and new bearings in the undersddle bracket ). I didn't feel the customer had to take up the cost on my labor to fit the parts. With those prices and all the parts bought at once, didn't seem right.
All kick outs on 3 axis were bad. Linkage to spindle start was sheared inside the speed shifter bracket.
Good machine with no good attention.
