TK B20 owners
« on: June 04, 2017, 04:30:21 PM »

 I should have done this years ago, this morning I converted the tensioner to acme treads ,  Works great counting 1/2 turns now it takes 5- 1/2 compared to 18 with the fine threads and it turns easier as I put longer handles on it like the TK2000 has.  Steve

Steve,
More details...  shaft size, thread count.  Did you have a new block made or just have a machine shop bore out and re-thread.  $$

Tom
    I used 3/4"  shaft with 6 tpi  with a steel nut welded to a 7/16 plate about 4 " long and wide enough for the 2 mounting holes. I welded the nut more towards the outside end of the plate so I can squirt some oil on the treads from the wheel side.  On the handle end I screwed on a acme nut and then welded it, then welded a 20" long 5/8 bar for the handle, still have get some knobs or make some wood ones.  https://www.mscdirect.com/product/details/65137374   This tensions up really  easy  5 1/2 half turns after the blade is snug.  I'm going to keep the old tensioner with me just in case but I see no problems unless  my weld breaks

Good for you Steve, these mills are built by folks like us, maybe they never gave that part a second thought or maybe it was just cheaper to use the all thread rod. If I find something I don't like on my mill I change it. Its a rare piece of machinery that can't be improved. Frank C.
