Re: Caselman, anyone?

A pre-heating would be preferable, if not the welding should contain a nickel alloy to reduce the tension, afterwards, if I remember. an income with 200 degrees during 2 hours.

Yes, the firing valve. I thought the DOM tubing had a higher carbon content than it does.

caselmanproject,

Since you are a welder, do you have any thoughts on the welding of the valve base to the receiver?
You speak about the firing valve? scuse me, the translator…
Except if you use an electrode special, the treatment termic is not necessary on mild steel.

A picture of the two parts would give me more precision.

Here are most of the parts I have completed, or mostly completed.

Re: Caselman, anyone?

Here is a picture of the striker follower showing where the slot goes. The dimensions on the plans would put it too far towards the outside of the part (further towards the bottom in my picture) and it wouldn't work.



I took a couple of other pictures I will link here.

caselmanproject,

Since you are a welder, do you have any thoughts on the welding of the valve base to the receiver?

Since that will take the hammering, I would think it would easily develop cracks in the weld if no heat treating was done. I am going to try without heat treat only until I have it working then will heat treat. I don't have a furnace that could handle the size of the receiver, so I will have to find somewhere to get that done.

Re: Caselman, anyone?

I will try to take some pictures of some things today.

I only have the plans that you can find on the internet. I studied them pretty well before cutting metal, and also as I am making parts.

Once I have it completed, tested and working, I will put together all of my notes and drawings on doing it.

I build all kinds of things. I am building this one since it is so much more powerful than the Drozd and Strafer type guns.

Welding skills will be very helpful.

Put some pictures up of what you have. I look forward to seeing what others have done, too.

TBK

Re: Caselman, anyone?

I take in note, thank you. You will put picture of evolution?

Is your first project of the kind? My only strong point in the field is that I am welder. :rolleyes:
You have another document or just the plan of 28 pages , not much information on the Web, and little believes that its work.
:sad:

Re: Caselman, anyone?

If you build it according to the dimensions, you will have some problems. I am also making updates from the original plans.

The pictures show a third screw holding the striker to the striker follower. Not an error, but only two 6-32 screws did seem a little weak for the only connection holding a striker banging away at 700 rpm.

As an example, the striker follower shows a 3/16" slot cut at a dimension of 9/16" as I remember. It should be 7/16". If you cut it to the dimension on the plans, 9/16", it won't work at all. Measure twice, cut once!!

Yes, I have met Jeff, and have held the gun shown on the table in your second picture.



I hope that you will put some pic of the corrections on the plans.


How much error you found?

Re: Caselman, anyone?

I gathered some parts, but, I gather as much possible information on the projects.

There are errors on the plan, but , for me which must all translate….:sad: I tests to target the problems future as much as possible.

Is for this reason that I waits with great interest the evolution of your work :smile:

Hi Caselmanproject,

Yes, it is good to hear of others with the same interest. I am making a lot of progress and can see the end in sight!!

Have you started making any parts? I would love to see any work you have going and discuss any issues.

Re: Caselman, anyone?

It even worked really well with .055" diameter wire winding the striker spring. It is .720" ID and 10.25" long. You can see my first attempt with some extra wire coiled on the end. I had to figure out how to do this on the mini lathe. The chuck spins freely in either direction, so I had to control it so it wouldn't let the wire go slack.

Winding the springs was a fun experience. Now I will never have to worry about not being able to find just the right spring!

Re: Caselman, anyone?

Here is a bolt spring I wound and the couple of things you need to wind them. This one used .031 music wire and was wound sitting on the floor using the hand drill.

I never expected them to come out this good!

Re: Caselman, anyone?

The bolt, the bolt body, and the spring guide are at the top.

The striker follower is right below that. I added a third hold down screw as you can see in the picture. That is how the Caselman I saw looked. The plans show the slot in the wrong location.

The receiver tube and the trigger housing are at the bottom. The radiused blocks are in the trigger housing and mounted in their actual position. The slots on the bottom of the receiver housing are for the trigger and a window to weld the tank holder/valve. The magazine goes where the cut out is on the trigger housing at the left behind the silver screw head. The receiver slots are all finished except for the side one for the striker.

Caselman, anyone?

I have finally started on mine. So far, so good. Has anyone else built one, or at least made any parts?

I have the trigger housing, the bolt and bolt body, striker follower body, and spring guide built.

I gave spring winding a try and it is working out great. The first attempts were for the bolt springs. They are 5 1/4" long, .031" wire, with a 5/16" ID. They look quite "professional" even though they were wound with a hand drill while I was sitting on the floor watching TV.

If anyone wants to trade building ideas and stories let me know. I am keeping an updated list on the "plans" corrections and updates based on what I have seen and built.
