Here is a shot of the girdle marker that I made. Much simpler that the commercial versions. It consists of a 3" by 3" by 1/2" inch slab of aluminium having one hole bored through the top surface half an inch from one corner to hold a 1/4" flathead aluminium rivet, and a second hole bored, and tapped 1/4 - 20 for a set screw to hold the desired height for the girdle. The preform shows the girdle mark, and there is a spare rivet for reference. You can either resharpen the rivet when dull, or just replace it....they are not expensive. Woody Here is a photograph  |

Great job Woody! I knew that some one would come up with a simpler piece.

I was also going to order one. I know my husband has the material to make one of these.
Thanks for posting this.

Just a thought what if instead of using the rivet you tapped the hole and used a brass screw that way you could run the screw in and out to adjust the height and the head would mark the line.

So far the it looks like the aluminum will be more than the machine Amber was looking at. McMaster Carr is the only place I've looked so far though.

Tony:
Some where close to you there must be a scrap yard! I bought four feet of 1/2 X 3" bar for $3.00 at a scrap yard..........and the size is not very important just so long as it is thick enough to hold the rivet, and set screw. The material is not that important either. You could even use a hard plastic for the base. I thought it was quite nice of me to volunteer your services to Amber.

Would there be any reason why a block of hard wood couldn't be used?

We use a unit made from a wedge shaped block of wood and an aluminum pencil at the club shop. sliding the pencil up or down determines where the line gets marked...will post pics soon....

It marks the height you want the girdle of the cab to be on the edge of the blank.

Here are the pictures of the marker we use at the Club's shop.. Side view  Front view  Bottom view showing screw mount from below..  Adjusting the length of the pencil's extension from the block sets it to the right height on the cab..then just move the marker around the cab, or the cab around the marker.... Jeff |
