I started out by buying a cast iron counter weight at the scrappers to use for the two slides. A bit of milling was necessary to make the underside of the cross-slide parallel to the Y-axis of the carriage. Just about every taper attachment I have used, including brand new ones, had some slack that caused lag like that.
In between phone calls today, I managed to throw a chunk of scrap aluminum in the chuck and try out the attachment. I used a carbide insert cutter because that happened to be in the holder, so the finish isn't quite what it could be. It just seems worth testing before I re-make the sliders, just to compare HMWPE to bronze, aluminum or whatever. One advantage of this test was to demonstrate that the use of DROs to set the taper attachment is valid.

I milled a notch into both to allow the cross-slide to be removed when necessary without removing the taper attachment or the X-axis DRO.
Any flexing would allow the upper slider to rock, changing the distance from the taper bar.
Watching the DRO displays while moving the carriage shows that it takes about an inch of movement to take up the slack before the Y-axis display starts to advance.


I figured that the taper attachment should be pulling against the cutter, so I set up to cut from the chuck outward. If you look close and use your imagination, you can see where the parallel ends and the taper begins. If the take-up distance stays the same, it will show that plastic can be a viable substitute. A bit of undercutting at the shoulders allows the cross-slide to move all the way forward when the attachment is not in use. I couldn't extend the tailstock spindle far enough to test the taper, so I locked the tailstock quill and slid the tail off the bed. If I give it a smart snap into the tailstock, it tightens right up and needs to have the quill retracted to release it. Most of the details are as shown in the plans, with a few revisions, which will be pointed out. That's after hitting the Zero buttons on both just after the Y started to advance (slack taken up). My turned-down section on the test piece wasn't long enough to allow the taper to go all the way into the tailstock. The addition of adjustment screws (to rotate the carrier - similar to tailstock offset screws) might make it easier as well. We are not going to provide your information to third parties, plant tracking cookies on your computer, or try to sell you magazines or books. It's close enough that a bit of careful emery use (go ahead and cringe) at the thick end would make it usable, if it were made from steel at the same setting.
The frame, wheels and guides are of cast-iron, the spindles, bolts, etc., being of mild steel.
These materials will make a much more satisfactory and workmanlike appliance when finished, than if it were constructed mainly from woodFig. The gearing up, which is absolutely necessary, may be effected by a cycle sprocket wheel, bolted to a small face plate on the lathe, and a hub wheel on the pulley spindle with a suitable length of chain.


The band saw will require a good deal of power to drive at anything like the prescribed spied for these tools, which is about 4000 feet per minute.
The pattern for the pulleys should be constructed in seg mental ribs, glued and pegged together, and turned in the lathe; or the wheels may be purchased complete.
A small pattern will be required Tor the adjustable slide which carries the upper wheel, and also for the lower saw guide under the table. The top guide may be a mild steel forging.When the castings are received, fit the tenon and base to the bed, drill holes for the holding-down bolts and clamp plate, and place the frame close to the lathe centevs and transfer the height on to the casting.
Next lap the train of gear wheels in mesh flat on the bench, and carefully measure off their centers and transfer them to the casting by holding a square with the stock on the casting, and the edge of the blade exactly over the lathe center mark previously mentioned and measuring off the centers on to the bosses for receiving the intermediate and driving pinions.Another method is to first secure the 4 in.
Hold them in this position and bring the frame up close to them and holt down and scribe the centers on to the chalked bosses of the castings through the bored holes of the wheels, taking care not to have the teeth too deeply in gear while doing so. 1, and with a hack saw cut the slot right down to receive the stud in the adjusting slide which carries the upper wheel.
Mount the wheels in position, stretch a fine wire around them and make a rough pattern in wood of the top saw guide.
5.The thrust of the saw is taken on a small, hardened steel roller, and the side play is avoided by fitting two small, hardwood guide blocks C, retained by the thumbscrews, which are set upon small pieces of sheet brass, D. If rubber bands are adopted, provision must be made for the extra diameter of the wheels, and the pattern lengthened at the outer arm carrying the top saw guide.Fig. 8 shows a method of constructing the pulleys from layers of wood cut in sectors of a circle, glued, pegged and lap-jointed together, and fitted with a gun metal or cast-iron flanged hub, which is attached to the wheel with screws. 9 shows the method of forming the bearers for the stud and the spindle of the intermediate wheel and pinion.
