1. Not all parts will receive dedicated dowel pin holes.

2. Fit a dowel pin here to keep the adjacent parts aligned.

3. Objective To compare the long term effectiveness of three types of dowel pin as treatment post core crowning.

4. What would be the bottom surface of the block is then skimmed flat, and locating dowel pin holes are drilled.

5. Precision Clevis Pins These pins combine the locking capabilities of a Clevis pin with the precision diameter of a dowel pin for a tight fit.

6. A center longitudinal axis (17) of the fixed dowel pin (11) is arranged at an acute angle (W1) with respect to the bottom surface (5).

7. A dowel pin with the adjustable diameter comprises a pin body (2), a shaft sleeve (4), at least two sleeve barrels (6) and an elastic ring (8).

8. The connection type between the vertical guide plate of the vertical adjusting mechanism and the positioning plate can adopt compression-fitting connection or dowel pin type connection.
