27 Hudson F-Head Sizing and Securing Water Jacket Discs

Unknown

Hi Again,



I am ready to place the head back and secure it. I have learned from

prior messages the two open holes in the center of the block were

formed for sand casting purposes.



I have purchased disks, but I am not sure if I have purchased the

correct size or shape. The two center holes adjacent to the pistons

measure 1.5".



The discs I have purchased are 1 3/8" curved steal discs. If I hit

them while in place they may flatten out to the required size, but I

feel uneasy about doing this.



Questions:



1) Should I find flat disks the 1.5" in size or?



2) Should I attempt to somehow sodder the discs in place or?



Thank you,



Rick Gatling.
