1. Kwik Way 041
Repair to the spindle lash clamp

2. The machine was purchased with the gearbox casting for the clamp broken and missing

3. I indicated the stripped gearbox on a Bridgeport and milled a shelf 1” wide.

4. An 1.5”X1.5X12” segment of A36 was machined in the approximate shape of the original
casting

5. The A36 piece was drilled and doweled and attached to the gearbox with four 3/8”-16X1”
SHCS, tapping directly into the gearbox casting.

6. The gearbox was then set up in a TA14 taking care to align the boring bar .003” high.

7. Original bore is 2.758. Removed .015” per cut until reaching 2.740”. At this point .002”
cuts were made until tool bit cleaned a .010” wide area on the original bore adjacent to
the parting line with the new piece.

8. The gearbox then went back to the Bridgeport and the new clamp was split with a .0625”
saw.

9. The ID in the gearbox had .0007” interference with the spindle sleeve. A .003” shim was
added between the piece and the gearbox. A 2” travel dial indicator was attached to the
stop adjustment clamp to assist in defining depth of cut. The broken plastic fine feed
wheel was replaced with a 4” aluminum wheel.
