but I'm liking the way this is looking. Fourth coat of gloss wipe on poly, still wet. Probably will get two more coats. Flame box elder about 8.5" tall and hollowed to about 1/4" box elder vase.mp4
Here are some pictures of my deep hollowing set up. I have about 22" reach with it. It's built around an inch and one quarter diameter bar. The bar is 4140 prehard steel. That should be stiff enough to reach out about 20" or so. I have about 22" of reach from the cutting tip to the torque arrestor that is welded to the round bar. There is a threaded stud in the front corner for attaching the laser pointer post. This picture shows the threaded stud a little better. The trap that holds the boring bar is made from two 1" diameter black iron pipes. The top pipe is adjustable so the trap can accept larger or smaller diameter boring bars. Eventually I may add a 1 1/2" bar but I have no immediate plans to do so. If/when I do it will be a simple matter to use the same trap for either bar by loosening one bolt on either end and repositioning. This is the "business end" of the hollower. The boring bar came from Grizzly as a set of five double ended bars. In addition to the angle slot the other end has a straight slot. I have both a 3/4" set and a 1" set of bars. The order from Grizzly also included 1/2" 3/8" and 1/4" boring bars. I could see no use to keep those so I gave them to my brother to use in his shop. This is just a view from the tail stock end of the lathe. I figure I have probably less than $150.00 in this rig. For one this heavy duty, retail would be in the $500.00 range. With that said, I don't believe the retail ones are over priced at all. It's easy to look at material cost only and think they are charging too much for something like this. In addition to my material cost there are several hours of machining that went into making this. My brother is no slouch at metal work. His normal shop rate would've pushed the cost of this well over what I would pay retail. Add to that, the cost of welding and there is no way it could be done for less. I'm blessed to have had someone to help me for hanging out together and a bowl or two. Several times I showed my brother how others had made theirs. Always his response, well we're going to do it better than that. As an example, the trap on others I've seen simply used machine bolts and a bunch of nuts to make the assembly. Adjusting the size would involve tedious loosening and tightening several nuts. Either that or they were welded to fit one size only. It will be a couple weeks before I get to try my hand at a deep vessel. I still have to make my steady rest and laser assembly. When I do get it all together you've got to know, I'll post pics!! Steve
