I bought myself a little present Christmas before last, a Langmuir Crossfire Pro plasma table. I've been messing around with it off and on since, nothing serious, just playing around. I did make a few things to sell to help pay for the thing, it was reasonably priced but still a chunk of change for an old guy on a fixed income, ya know? one of the things that turned out ok was a few runs of motor mounts patterned off some thrashed Hurst mounts I had in the scrap pile. these are some pictures snapped during the process
I don't want this to come across as advertising just a brief show and tell of a fun little project I did out in the garage
There is a need for those, they will get snapped up quickly. Now find some of the Pontiac versions and make a run of them.
Nice work as usual Paul! I like how you use your press as a brake. I should do that to mine. I second the request for the Pontiac version. Maybe the Chrysler Hemi version too.
@Paul I just helped a friend set one of the Longmuir CNC plasma tables last month. Kind of satisfying seeing the cutter move on it's own isn't it? I had thought about cutting out some Olds motor mounts because they looked like a good project to try. Looks like I was right.
This is the secret. It (they) goes between mount and engine block. It’s just kicked up in this photo (using mount only as a mock up support) but Hurst back in the did supply them.
Very nice work including the welding! As someone who has some experience coming from a company who had their own in-house manufacturing for sheet metal, I can appreciate the nesting of parts to minimize scrap, and figuring out those bending lines, and allowing for the material thickness for bends. Noticed the original mounting holes appear to be all in the same plane, but the lower hole in yours in not. Just wondering why?
Iirc from mine almost 5 decades ago, the mounting holes actually should form an arc, not a straight line. BTW, Paul, those do look nice, For some reason, I'm remembering my set didn't allow the use of the stock pump, so electric was needed. Marcus...
Those are good looking parts. I hope that you so well selling them as they are needed. As someone else mentioned, do the Chrysler mounts, and then the Cadillac mounts which are very similar to the Chrysler mounts, needing only minor changes to fabricate them.
duplicating mounts for other engines would best be done by finding some original mounts and engines they are designed to fit. I suppose one could do it without the engine to bolt to but I'd want to verify fit before putting them to market.
I have the files for an outfit called "Send-Cut-Send" to produce the early hemi Hurst style mounts. Since I don't have my own machine, this was the best way for me to go. Two sets were less than $100 (including shipping) once I got the files. I'll give a "shout-out" to @bchctybob for providing the originals. I haven't welded them up yet (I have to drag my extra hemi out from under the stairs), but I did hot glue a set together and I'm sure they'll work. (The triangular piece sticking out inn the pictures has to be bent to fit as well.)
looks like they need holes too? $50.00 a set needing holes, bends and welding? good food for thought, thanks
Drilling holes and welding metal together I know about and have done before. Cutting all those pieces out of different thicknesses of metal? Not so much. Buying such a piece of equipment is not even on the horizon at my age and situation. Just another way to skin a cat. Sorry, I forgot to say yours look excellent!
When I was making the Hemi mounts I had one of the local steel suppliers cut, bend and weld everything. They did a great job but today I'm sure the price would be alot more...7 years ago I was paying $20 per piece in batches of 50 so be sure to make enough margin to feel good about the time invested.
