Thanks cutter for the post processors, I will try them hopefully today as I was out of town yesterday.

10-4 Bruski

Let me know If they work or not.

I have 164 post processors

Cutter,

I have been using BobCad-Cam V-24 as my cad software but I also have and still learning the Fusion360 cad. Does the post processor have to be compatable with either of those, or just with the controller software which I think is the V2XT or machine came with operating manual for the Boss10.

A postprocessor has to be compatible BOTH with the cad software being used AND the machine tool. For example, can\'t use a Bobcad post with fusion or solidworks, it will give a error and not generate ANY code. If its not compatible with the machine, it will generate G-code BUT that code will not run properly on the machine.

Sparky,

How can I make these post processors compatible with Bobcad?

bruski

Short answer.... you can\'t. A post processor has to be written/coded from scratch for the particular cad/cam software used. You CAN usually modify / tweak a post, for your cad/cam, to make small changes to suit your preferences for your machine.

I looked on the bobcad website, they appear to have the post you need. (not sure what version bobcad you have) You can download it there.

I have all the processors from bobcad and they are not the exact one that I need, but they work. I have to make a few changes with the G-codes where the spindle speed and rotation directions plus auto stop spindle or start spindle. There can\'t be any M codes on the same line with any other S code.

I see. Sounds like you need to modify the post you have.

Half inch diameter for the bolts does seem on the small side.    The .22 versions are roughly 7/16 and look at the difference in the diameter of the ammo.    A bigger diameter, 5/8???, bolt would give more room for the pieces.

I know there are hardly any posts on the forum these days BUT..... I look daily and have a lot if interest in your project.    I have the barrels and plan on a .410 shotgun, 6 barrel gun build next.   As I always do, I expect to shamelessly steal your ideas.     Your gun design elements should apply to any center fire version and ideas for those are a rare find.

I am fighting the temptation to inquire with Cutter about that extra set of 38/357 barrels he has.

Just need the right bait

I know its very premature BUT... has anyone seen plans for the bruce feed magazine? I sure would like to make one for the 357 when the time comes. One for the 22 also for that matter.

Somewhere I have copies of the patent drawings for the Bruce feed. If that will help Iâ€™ll look for them.

Cutter emailed me the patent drawings which I had not previously seen. Thanks though, and don\'t be a stranger here.

I try to visit forum every chance I get. Iâ€™m really excited about this build and seems like this build has a lot of interest. I too think the Bruce feed would be the way to go.

It is nice to see all the dust blown off the form and some activity.

I feel a gat needs a good magazine capacity and a bruce should be a lot easier than a drum and probably hold nearly the same number of rounds. Alternately, I do have the D&E plans for the broadwell drum but thats a lot more complicated than the bruce system.

4171 · « **Reply #93 on:** June 23, 2018, 01:51:46 PM »

I have those plans too. Thought that it could be adapted to the RGG but seems like a lot of work. Bruce feed looks simpler and could maintain lots of rounds if a guy made cartridge blocks to feed it.

I made one for my D&E and it is very easy to load with the loading blocks vs the stick magazine.

Is that you with the youtube video of one on a D&E? Do you have any drawings or further info on yours?

Hey everybody,

Here is a picture of two new style 357 bolts in the making. They are 4 inches long with a .750 diameter rear end and a .437 diameter front end and that is about 2 inches long on the flats. I plan to use firing pins from a 1917 Enfield rifle that will be reworked a little. Not sure on the extractors yet.

Looks great Bruski. Do you have a pic of the bolt from the prototype gun?

bruski · « **Reply #99 on:** June 28, 2018, 02:36:33 PM »

Sparky,

That is the prototype bolt design with a heavier firing pin and a rear cam follower. The slot for the ejector pin is not milled yet or the cam follower milled yet as I am waiting for the Enfield firing pins to arrive first. The flats on the forward end of the bolt are closer too 2.200 inches long instead of the 2 inches in the picture description.
