How to make custom hood peak tooling

In this tech / How to video i cover how I make custom lennox ( pullmax style) tooling for putting in profiles and body lines. From casting an accurate mold, through machining and ending with putting the peak profile into the custom engine bay panels.

[@TheCarlhungness]

The best of the best. What a marvelous teaching video, and you really show us step-by-step how it's done. Sure makes a fella want to get into the workshop and start making pieces. Thanks so much for donating your time (and journeyman knowledge), it is really appreciated.

[@adambergendorff2702]

Really liked the custom Jig for welding the tooling, Great example of the repeatability of the Cleco fasteners, pouring the body filler reminded me of making sand casting dies for intake port fillers 40 years ago. Love seeing tooling made because very few people realize a pullmax is useless without all the different dies for each custom contour!

[@bobbycole5597]

Pay attention kids. This is what put our past in the present. Tool and die makers are few . Talent is what he shares. Thanks Mike

[@theoldstationhand]

What a great video, always wanted to know about making tooling and was surprised/happy to know that ordinary mild steel is adequate. Cheers

[@cornfieldcustoms]

Thanks for checking it out. It would take a ton of use to wear out a 1018 tool. most of the tools i make are 1-2 uses for specific parts

[@bluejayfabrications2216]

I have been working on something similar for creating a body line on a ute quater panel
I use a thermo plastic called polymorph its a low temp plastic 60c
But at room temp 25c its as solid as nylon its great at pulling profiles from and takes way less time then waiting for filler and its reusable
It can also be used for dies directly for things like alloy or brass

[@cornfieldcustoms]

Thanks but I will stick to the way I am doing them

[@leongrice6664]

Loving it.

[@cornfieldcustoms]

Thanks

[@farmer-jon]

That turned out beautifully! How would you do it if the bulge started smaller at the from and got larger toward the rear of the hood? How would you do the increasing radius on the sides?

[@cornfieldcustoms]

If the profile was not consistent in width i would have made the tooling to do half of the profile, then done each side individually.

[@farmer-jon]

@@cornfieldcustoms is there any way you could you please do a video someday explaining it? I am more of a visual learner. Thank you! 🙏

[@cornfieldcustoms]

I will try to film and post it next time i have one of those profiles come up

[@mikeclarahan6770]

great stuff, Mike! How many passes thru the machine to get that profile start to finish?

[@cornfieldcustoms]

I did five just to ensure no tooling marks

[@TBS_Machine]

Thanks for an excellent tutorial, I believe I could make form tooling from this.
Question: is there any functional difference between the Lennox and a Pullmax ?

[@cornfieldcustoms]

Minor differnces in operation but the functionality is the same

[@williammurfin6354]

Mike, That is so sweet. Just wondering is that centre section going to be your air intake for the engine?????

[@cornfieldcustoms]

No its just a cover

[@williammurfin6354]

@@cornfieldcustoms Shame. I've always wanted to incorporate a air intake like that . They did an open style of those on our Early V8 Supercars Race cars and so far I haven't really seen one done at a high end yet.

[@kennethstaszak9990]

Plumbers setting putty should work well for this too.

[@steeltree-fabricatingandcu3796]

Use the pin gauge the get a rough profile
Mark that on a 2x4 cut the rough profile out of the 2x4 you could use hard wood 1” thick here too
Coat the wood with bondo and fiberglass resin mixed together and stick to the surface let it harden
Pop it free and and sand the excess off the sides
Wax the surface to keep it from sticking

[@cornfieldcustoms]

why go through all the extra steps? your doing almost the same thing but using the pin gauge and having to cut a 2x4 to accomplish the same thing

[@steeltree-fabricatingandcu3796]

@@cornfieldcustoms
I actually use the wood as a profile gauge later
You can make it longer
It uses less bondo
Using hardwood like oak it holds its shaper over time
I love the Lennox
I have a Japanese nibbler I’m converting to a pull max
It worked fine but I wanted a longer stroke

The problem is there is no set weights and beats. Its all by feel and watching what the metal is doing

I was expecting the panel to get narrower so the cleco's wouldn't line back up.

I left the tooling tight so it would stretch a little and when i planished out the weld seam i had pre stretched it some

[@alandavis6429]

Well you did real good explaining what to use until you mixed polyester resin with bondo to thin it. Those 2 polyester products are promoted with completely different products, benzoyl peroxide for bondo and methyl ethyl ketone peroxide for the resin. Had you put MEKP in the resin before adding it to the bondo you would have properly educated your followers, as it is you conveyed bad information.
