HiI am ready to bore and tap the hole for the vent in my aluminum Thomas cylinder head for the Ford A. What is the normal diameter used? I don't want it to be bigger than necessary. Also, I can't figure out any practical hold down system for the fuel tank in the center section that wouldn't cause protrusions under the fabric on top of the wing. Is it OK to just cover it with polyfiber and consider it done?DonMinnesott Beach NC________________________________________________________________________________

Hi DonCould you use some nylon "banding" to secure it. It seems a lot to ask of the fabric. We use to secure boat fuel tanks to their platforms using this method. It went around the tank and the platform and had a neat little wire clip that enabled it to hold the tension once you had tightened it.The strap was very stroh and measured about 3/4" wide and a 1/32" thick. Hope this helps.Best regardsSteve in Maine>From: "Donald Lane" >Reply-To: pietenpol-list(at)matronics.com>To: >Subject: Pietenpol-List: steam vent>Date: Fri, 16 Mar 2007 16:00:34 -0400>>Hi>I am ready to bore and tap the hole for the vent in my aluminum Thomas >cylinder head for the Ford A.

Subject: Re: Pietenpol-List: steam ventRegarding the nylon straps for tank hold downs. I have stainless straps on mine now, but I am going to change them to nylon. The SS is too thick and bulky and will show under the fabric. Dan HelsperPoplar Grove, IL.************************************** AOL now offers free email to everyone.

Don,My steam vent hole is about 3/4". I'd say this or 1/2 is fine, you're just venting steam.Regarding the tank, I feel you should hold it down with something other than just the fabric. I have seen a guy use nylon straps as suggested, and it worked for him.Douwe________________________________________________________________________________
