Welcome to my world! Ka-ka happens, eh? What kind of gun work are you doing Mike, if you don't mind me asking?

Actually I am working on several: I just built a .223 bolt gun using a Remington 700 SA receiver and a barrel I had as well as some other parts/pieces I had laying around. I am also making a 1903A4, I also have a Enfield No. 4 I am building, a SVT40 and a Isaphore 2A. My "day job" for a long time had to do with firearms and I still dabble in them.

Simplest mill start would be flat brackets. Add some slots and holes for mounting. Or slots for lightening weight.
Custom role bar gussets are easy.
Make your own motor plate. And /or modify one for accessories.
I believe on my thread I detailed many items for ps bracket.
Milled flat plates and turned round standoffs.
Brackets you will have a million of them.
Removing the warning labels one at a time.
Nature will take care of the rest.

I agree, I have already been milling a number of things as well as turning some things on the lathe. I have no doubt the mill and lathe are going to be extremely beneficial.

Finally got back to this project and picked right back up where I left off. For anyone coming in late, I am attempting to cut out and repair all of the ugly. The window channel in the rear had some issues that I needed to address and am doing so now. the drivers side was/is the worst so I decided to attack that one first. It took me a long time to get this done, lots of filing, measuring, etc. I now have to get this welded in and then move over to the other side.

Well, I was able to get a little work done on the car, got the left side sail panel welded up. I was thinking I would try using TIG for the body panel stuff but to be honest, it is just too slow. I do use TIG for a lot of stuff but I have come to the conclusion that MIG is the way to fly for at least what I am doing. Perhaps if I was working on all new sheet metal it would be a different story but for now I am sticking to MIG.

I am going to pick up a 426 mock up engine tomorrow, we will see how this goes. I would not say the deal is "sketchy" but it isn't all that straight forward either; people are such poor communicators especially young ones. I report back what happens, but if it works out it will be a very good thing.

Today was a success, I was able to secure the mock up block despite the 3 hours on the round. I discovered that the block was used to mock up a very custom 41 Plymouth being built; the car is super nice, exceptionally well engineered and assembled and sports an all aluminum 572. The builder told me that the owner has $500K into it already and it still doesn't have an interior, estimates the bill will be over $600K by the time its done. Awesome car for sure and I wish I could have gotten some pics but he didn't want me to take any.

So, now I have the mock up block, time to get moving...

Glad it worked out.

Still slaving away on the car, I had to order some AMD upper trunk gutters, mine are not super bad but it will be much easier to just use the replacement pieces.

I decided to remove the tilt front end to gain access to the front end so that I could mock up the engine/trans and make some motor mounts. I was pretty happy that it wasn't welded up as I was thinking it might be, there were really only a couple of spot weld. I am going to replace the down tubes and add some more tube to strength up the front end, plus I am going to increase the tube size from the 1.5" it is now to 1.75".

Put the mock up in the engine bay, tried to position it near where it will live. I am going to cut of the stock motor mounts and make something new because there really is not a good way to use them.

I do need to get a new steering box, I am looking at some of the smaller boxes. Since I have a manual box now, I would have to source a core and then have it rebuilt. I did look at some of the parts stores and online sources and stock one are available but I would rather get something that steers a little better than stock, plus I would like something smaller, I need all the room I can get.

So I have decided to go with a coil over conversion for the front suspension. I talked to Denny at HDK (does A body stuff primarily) and he explained how he does it, some of the issues and limitations. I am going to have to fabricate a different upper shock mounting point if I am going to use the stock LCAs because the nature of their design does not permit a shock with any length. My other option is to get tubular LCAs which I could do as well (or do both). I am still looking at options to see what best suits my intent. I am looking at something like this;

Well I have decided that I am going to go coil over up front for sure, going to use some tubular LCAs and go from there. I just got 3 sticks of 1.75 DOM to redo the front end; going to be "beefy".

Spent some time working on the car today, removed the dash (which is definitely out of a 68 Charger) and the heater box (which has been chopped up some). I am in the process of trying to decide how to remove the interior down bars; I will have to do some reinforcing and redesigning I think. My intent is to make it look pretty stock despite all of the changes.

It has been a little while since I posted on this, so I thought I would do so. Unfortunately not much to report on the car, I have been busy working on my shop or better said some of the equipment in the shop. I am putting a DRO on the Z axis of my mill and also the X and Y on my lathe. I am waiting on some LCA's for the RR from Hemi Denny, so there is some movement on the car. Hope all had a good T day and even better coming Xmas.

I'm enjoying watching the build Mike and it's interesting the directions this goes! Question- if you're now into tubular UCA and LCAs why not put a rack in it and lose the OEM K-frame for a tubular one and also solve your engine mounting problems? In for a penny......   :cheers:

I have considered those options, however I am just not "there" when it comes to the tubular K frame and R&P steering. It might be a cost issue, but honestly I just would rather stick with what I know which is the stock K frame and steering. I am probably going to use one of the smaller steering boxes however.

Currently my mind isn't on the car all that much, again I have been focused on shop equipment, just upgraded my bead roller today, its a HF unit that I modified some time ago but it had some flex in it. I have a large selection of dies and it comes in very useful at times. It isn't quite done but will be soon (tomorrow). Also, I am working on getting DROs on the mill and lathe, but I also need to get some new lighting in my machining area (I have the shop set up with in sections). I am having to send one of my lathe DRO slides back, ordered it too long, so that will be on hold for awhile.
