1923 Mack AC Bulldog 5 ton


Recommended Posts

The work on the radiator cap is extremely well done.

Did he do the wheel himself? If so what did he use fro the wheel it self? Mine are all a rubber compound over canvas and wire and ALL need to be restored.

I'm jealous of his perfect hood. I need 5 AC and 1 AC-6 hoods. I've gotten the original plans from the U.S. Patent Office to make them. Another member on here is getting geared up make cab panels for the early AC's Paul

Thanks for the wheel info. I have been to a company that does resin casting for Victorian Era Home details and used centrifugal set up to help the flow of the material. I never thought of resin for the restoration of the wheels. Thank him for the idea. Paul

There is a definite market for a steering wheel restoration service out there if anyone has the time and skills to develop it. Almost all of the AB's and AC's that are restoration candidates need it done.

It would make a great part-time retirement business for someone.

Money, sex, and fire; everybody thinks everyone else is getting more than they are!

Paul, keep us posted on what you find. The exchange of information and advice is what keeps the hobby going.

I have asked him about making more steering wheels and he might. He wants to do some more research into the rim materials. He is enjoying retirement from his day job in manufacturing but he has a secondary manufacturing business making small parts for the aftermarket auto parts trade. That also is something he is trying to get away from. He has seen many things in his years in manufacturing because everything used to be made in America.

He has diverse interest ranging form the Bulldog to a hot rod C-10 and a Ram Air IV GTO conv to play with.

It doesn't cost anything to pay attention.

I will tell you one thing I'm looking to try for the steering wheel is to scan the dimensions from a relatively intact wheel to a CAD program and have the parts 3-D printed with a Cross Linked Palomar Resin. I want to do it in two halves to fit over the wire and bond them together with Master Bond Structural Aerospace Epoxy that is designed to bond metal and fiber reinforced composites air frame assemblies together. The material CLP resin has the feel and look to the original MACK molded hard rubber. This was developed for the Rutun- Scaled Composites all composite Triumph business jet

The 3-D printing works very well but is some what costly. I've had a few things made. The inside cab pieces for my B model air intake cost me $120 and almost $250 to have one AC head light mount scanned and printed so I can have a mold made to cast them. Paul

Paul, it sounds like you have a game plan! I am not savvy enough to fully understand 3 D printing but some of the items made using the process are amazing. With good measurements and a well written program, it could be the hot ticket.

It may not be cheap but to bring long obsolete parts back could help a number of people.

The 3-D printers and Vector scan systems are coming very affordable. A basic 3-D is about $700 to $1000. The one big enough to do the steering wheel is down to $3900 to $4200. Even Radio Shack sells the basic 3-D and supplies now. When we get settled in Va. I'll purchase a system that can do a 24 x 24 cube size part. I already own a Vector machine that I use with my CNC Profile Mill, Plasma cutter and Tubing Bender so it's basically a software up grade. Paul

You are going to have all the toys!

Paul,did you get the AC6 you posted the other day?

It's paid for and transferred to me. Before the week of rain I had it tented and all the bee nests killed. So I can remove the house counter weight and boom to move it as soon as it dries up to work on it.

As for owning all the toys Jim, I bought a lot of machines and tools when Grumman Aerospace and Fairchild-Republic Aircraft companies closed up on the Island. Most were bought by the pound.

Nice AC!!

Over here in the UK we have done quite a bit with the 3d scanning and either printing or CNC pattern making; it is particularly good for the smaller and more complex parts.

I am soon to make a hood (and a cab) for my AC - other than the louvres it is pretty straightforward although the double folded seams might require a bit of practice. It will probably not be cost effective to make them for customers in the US but I will be making the timber jig to form it on so the least I can do is to post some pictures here once I start!

Please do!

I've copied and scaled up to full size the 1923 MACK hood plans from the U.S. Patent Office. I was also fortunate enough to be allowed to make and in side and out side RTV molds of the hood louvers. This will allow a resin copy to be cast for a CNC copy to make louver press dies with the curves. Paul

That is the most perfect hood I have ever seen!! It almost looks too perfect! Paul
