Does anyone here know of an easy way to make one of these? Or what you can use? Let me know? txoldrodder@gmail.com
Go to a thrift store and look at pots and pans. If you see a section of something that will work cut it out with a hacksaw and figure out a way to mount it.
Then pay someone who can. It's going to be hard for someone to suggest something that works for your specific application.
Google 'tear drop shaped panels' and see what comes up. I have seen (and bought) preformed pieces like that some years ago. Ray
That still doesn't tell anyone much. What size does the blister need to be? How deep? You'll need to figure that out before anyone can help you. Or buy a blister from above and make it fit your application. If I was you, I would have someone make one once you're ready. Or at least try to make your own, what do you have to lose?
Every cowl steering setup is different. A lot depends on what you use for the steering gear and how it is mounted. You have the cart before the horse, get the steering set up and working correctly then worry about the aesthetics of it.
Buddy asked for a hand converting the right side of the '31 firewall to '30... he cut out the teardrop, sat it on the bench... After we were done he holds it up and says, how about a cowl steering's cowl blister ? HHMMMMMMMM.......
Just remember to leave yourself enough space to get a pitman arm puller in behind it, they are big and it'll take muscle to get it off, it is a major piece of work. Most that I see have the blister go over the top of it with a slot cut in the bottom for the arm, make the blister removable to get to the pitman arm.
I punched in teardrop blister for cowl steering on egay and two showed up . They are from the UK , but it's free shipping. For the price though ,you could by a mallet and some MDF to make a hammerform. You might surprise yourself. Bill
Here ya go. Cowl blister the easy way. I'd go with the suggestion above and not do anything about the blister except think about it until you have the steering all in place and working and know what size you need. http://www.highway99hotrods.com/Blisters/orderb.htm t
Or take a large exhaust stack elbow from an 18 wheeler and cut out the section you need from the bend area. Depending on where you make the cut defines the shape of the blister. Do a search on the main forum for blister and there's bound to be a few good ideas. Sent from my iPhone using The H.A.M.B. mobile app
My blisters are designed to work with my steering kits. Here are the links: http://www.jalopyjournal.com/forum/threads/cowl-steering-pitman-arm-***embly-kits.1046504/ http://www.jalopyjournal.com/forum/threads/custom-cast-cowl-steering-blister.1033023/#post-11974302
The steel teardrop blisters I have seen are great and affordable, but the problem is the length 18" is a bit long for Model A cowl steering setup! Fourspd2quad's are real nice but way out of my price range for my budget build!
I found a aircraft salvage place here in San Antonio out by the airport I'm going to check it out and see what they have! Thanks for the help!
I did this one on my T. I,m not a metal shaper by any means. I started out with a maple timber and carved a concave hole in it and then pounded my Alum. into it. When I was finished I didnt like the look of it because it looked like a huge pimple so I did some more carving and turned it into a teardrop. So the one on the car is my second attempt.
Check out cheap-o aluminum feed scoops. Cut the handle off and m***age to fit. They are usually less than a ten spot at Tractor Supply, Etc... Got 2 different sizes to work with on Amazon for my project bot for I think about $12. That suggestion was made on a thread here somewhere so not my idea.
Hey Green73! Do you have any pictures of how your feed scoop blister turned out also how much of a lip did you give it?
Haven't even started modifying my stuff yet. Just a collection of parts. I am thinking about having a friend tig a few tabs evenly spaced around the perimeter for screw holes, and maybe put some rivnuts in the cowl for mounting. Still running the layout through my head. I may just sacrifice one for a test to see how it will look on my mock up cowl panel.
Snagged a few pics of some of my parts. I arranged them in an idea layout. As you can see there will be plenty of "fitting" to happen. That pitman arm is a universal torsion bar arm from speedway (Again another borrowed idea from either someone here or elsewhere on the interwebnets) . I figured it is long enough to be tuneable to pretty much any length someone may need. It is the same spline count and diameter as the F100 box. It is also pretty cheap. The only downfall may be it being straight. I don't know yet if I'll need any offset.
