Are you talking about my bin system?
I shipped my first order? The member only bought a flash hider but that still counts
I also talked with the shop and our Bespin Scope Bracket Disk prototype is on the schedule for Monday or Tuesday.
Yes, sorry I should have quoted.

No worries.
The bin system is one of the ways I keep everything straight o the long protracted projects
I just had to re-fresh the boxes so I went with smaller units.
They are worth very penny
Bronze scope update:
My second-to-last order is ready for me to pick up and I will have my last batch of wax scopes ready to go to the foundry by next weekend. If you have been on the fence on whether to get a scope or not, NOW is the time to contact me. Once I've taken the last batch to the foundry, that's it.
The turn around on these will be 2-3 weeks. Then the whole lot goes to Bobadebt for machining.

this is off topic but I'm curious, is there any video on youtube explaining how brass castings work with wax? i would love to see the process to make these, even if it doesn't show the scope just so i have a idea of what you are going through
if its cast anything like this its a long process, holy cow

Yes, this is essentially the process. Thankfully, I don't have to take apart the scope in order to make the mold, so I don't have to re-join the parts in wax.
The wax sprue attachment process is pretty much the same, but only 2 sprues are needed (on the bottom of the feet). Rather than painting on plaster for the waste mold, the sprued-up wax gets dipped several times over several days into a silica investment material that hardens. Once the coating is thick enough, it's heated and the wax is melted out, leaving the cavity. Then the bronze is poured into it. Then power tools are used to break the investment off the bronze. I receive the scopes after the investment has been taken off.
There are two things that can go wrong during this whole process. 1) the silica waste mold isn't heated enough, so when the bronze is poured in, it doesn't fill the mold properly. 2) if they don't take care with the power tools, they can nick the bronze scope. In either case, they reject the scope. In my last batch, I brought in 33 scopes and only got 29 back.
Bobadebt will be machining the sprues off the feet of the scope in addition to the other machining he will do.

That is the process but our scopes are poured as a solid single item.
Even if they were poured hollow they would have to undergo the machining process because it is impossible to get consistent wall thickness and it is impossible to create the counter bore and threads needed for the scope lens rings.
One MAJOR change we incorporated in this run is the inclusion of a machined light socket which means it is excluded on the casting
Not only does this give you the option to get the version of the scope you want but it also simplifies and speeds up the casting process.

The prototypes of those nuts should be done this week...I've very excited
I guess it didn't happen. Maybe next week?

I just spoke to the shop about this and they machined all of the disks last week now they are just waiting to get them onto a different machine for the knurling.
I hope everyone is happy with the new height raitios

Hey folks!
I've tried to stay out of all the convo here to help streamline the process. I wanted to toss in a possible source for the lenses for the scopes.
I made an E-11 blaster last year with a real M-38 scope on it that had no lenses on either end of it (got it cheap on eBay) and I ended up using a hole cutter bit on my drill press on some plexiglass which worked fine. My sister and mother are both crafters who use a lot of different objects in their crafts and they'd both done a project using these Cabochon glass domes for fridge magnets with photos below. Upon looking on eBay I came across what I think would work well for the sizes of these.
My M-38 rear glass I used something close to 27mm

For the front glass I used (i believe) 15mm:

Looks like buying in bulk could help the process of keeping things cheap for everyone.
It really depends on the milling of the scope blanks if the sizes have already been determined. I'm certainly not saying this is what needs to be done, I just had the thought about an inexpensive option that could be used. If something else is already in the works, please disregard this.
