Just the other day TLOML was talking about new chairs for the dining area... well certainly the lite came on....so I set about turning some/ a spindle to spec... ugh with 16 major legs, 12 stretchers, 16 + back spindles and 16 arm spindles I was daunted to say the least and wondered if I could add a lead screw to the OT and turn 36 inch spindle to spec and add the refinements by hand. ah sure I thought....
1 month later, 45$ ( plus some machine screws ) and a lot of fussing and such I added a lead screw powered by large hand wheel or vari speed reversing corded hand drill with leather sewing machine belt .
The screw is not timed to the spindle, the home made gibs have less than .001" play using laminate brass shim stock on the center guide between the ways, I turned the all thread rod using my steady rest and the ends are fited to oil lite bushings set in aluminum and milled the hard points, hubs, and later a new pin system for the OT index plate, from some salvage T6 aluminum (at a buck a lb) using the Jet and the cross slide for my ornamental attachment.Now that it all works the only thing different i would do is use a 3/4-10 all thread rod instead of the 5/8-16 ( flexs a bit) keep in mind none of this is hardened . I used a 5/8" x 3 in ATR connector to connect the coumpound apron to the screw and is releaseable so i can use the compound up close to turn/mill metal parts for shop stuff. Now TLOML wants me to build her a sewing table...yea . The run out on the coumpound is 1/32" from end to end over 36" and I almost feel confident ( or will ) to try some/ a pool cues....
Also I have a logger friend who finally knocked down a Yew tree by his shop and he had it cut into 4" thick slabs x 12 x12 turning blanks .. it is severly spalted and rotted thru the lower half , the upper is solid and will have some pics soon of that piece and I am in the process of turning one 12x12 x 4 from the lower part of the tree , if any one is intrested in obtaining some of the Yew , pm me and I'll let ya know whats up with it.The bearing on the reeves guide control went out so It will be a week or two before I am back to turning as SWMBO has some ( ugh ) f..t work for me to do.......and she took my credit card till it is done .... da nerve...:eek::D
the shot is my poor attempt to make alumin jaws for the SN2, the process is milling the splits but I should have use a solid piece instead of 4 segments as alignment is a bear . I'll know better on the next set.
