AN ALL-PURPOSE TITLER
41
Simple to construct, easy to operate, this all-welded titler assures accurate centering at every distance
HAVEN TRECKER, ACL
A NY similarity between the titler discussed, diaf^L gramed and pictured on this page — and any other such gadget pictured here previously — is not a coincidence. It's by downright intent!
Look . . . You'd think I would have been satisfied with that handsome hunk of machinery described last June by William Messner, ACL, under the heading, Build A Zoom Titler. For here was a strong design, swell diagrams and the result a titler which seemingly did everything but sing Dixie! But, no; I was not satisfied, apparently. For, as you all can see, I have borrowed Brother Messner's basic pattern and, to a degree, simplified it. Whether for the better or the worse, I must leave up to you — and Mr. Messner — to decide.
The two important changes (at least, / think they're important) which I have made in the Messner design are as follows: (1) the unit is of welded construction throughout for greater rigidity, and (2) the camera carriage is so designed that it may be run down the guide rods until the camera lens rests squarely on the titler floor. Of these two changes, I find the second to be of far the greater value in actual operation. For by virtue of it positive centering of all title cards — of any size and at any distance, within the maximum range of the guide rods — is guaranteed. How this centering is achieved we will come to in due course. But first let's get on with the practical business of building ourselves a titler.
THE MATERIALS NEEDED
In itemizing the materials needed for construction, the numbers in the left column refer to the unit as it is shown in the diagram. The number of such units required will be found in the specifications.

EASY TO BUILD In beginning construction, make your camera carriage first, for it will be instrumental in aligning the two guide rods when they are joined at top and bottom. If you have a Bolex H-16 camera with the Stevens square base, the carriage design may be used exactly as shown. Otherwise, the guide tubes and side plates probably can be used as-is, with only the front plate and positioning bars redesigned in relation to the shape [Continued on page 51]
FIG. 1: First step in centering is to prepare the crosslined guide card, which is then positioned under lowered camera lens.
FIG. 2: After centering the guide card in relation to lens, concentric rectangles are drawn up to maximum of 11 by 15 inches.
