My PKD Bladerunner pistol build.

[B1RDY]

Sorry to sound totally clueless but I would appreciate some advice from you more knowledgeable members.
In my time here and with this project here I find my self picking up on other members posts and discovering ways with my limited skills and experience along with working with very minimal tools to make this build the best I can. Simple things like swapping certain parts for others and using certain methods to achieve a task or process.
With that in mind may I ask a question.
The question is swapping out a weaver knob for a more accurate fillister high profile screw but which of the two screw shown in this picture I am replacing and if the ones I've purchased are good enough?
The picture showing mcmaster-carr is one that has been suggested as a replacement but that's in the USA and I'm in uk so hard to find from more local source.

Oh no, it's in the USA. Import taxes are a killer

Here's one that looks really close in the UK. 3/16" (10-32) UNF 3/8" to 1" A2 STAINLESS STEEL SLOTTED FILLISTER SCREW x 10 | eBay

Edit: Just read your second post, and it's the lower of the two 'knobs' that was a slotted crew in the movie, I believe (the one with the engraving on it that faces us in your picture).

Trying a light weight alternative for bullet tips and my first attempt is using the tops of zebra pens with a bit of filing some primer and some silver rub n buff it's a possibility.

B1RDY what are you doing with your bullets?

These where empty shells and I was trying to get something to act as tips, something like this.

can;t you use real bullets?

The kit is resin and the real ammo is very heavy and i don't want to risk breaking the swing arm crane.
I do have these .

 

[stussy]

ok, i get you.thought you didn't know where to get real ammo.

I appreciate that thanks. Just looking at options

Glued together the bolt assembly, and began test-fitting it into the blaster.

The tolerances are REALLY tight. I’ve been carefully sanding down parts to loosen things up, but there’s still more work to be done.

Also, there’s a substantial gap between the bolt’s endpiece and the rear of the receiver, when they should fit flush. May have to build one part or the other up with putty, or perhaps carefully sand the front edge of the receiver’s lever-groove so that the bolt slides in about 1-2mm further forward. We’ll see.

 

[Gregatron]

...still needs some more tweaking, but I’ve eliminated the gap.

With the bolt installed, the whole thing just comes together!

Ordered some replacement screws, which should hopefully be more accurate. Still waiting on the LED upgrade kit.

The slotted screw used in the movie might very well come from the Steyr itself

Looking good, where are you getting your led kit from and how does it differ to the one supplied. In regards to you rear receiver gap i drilled the tube with the bolt handle attached slightly deeper and used a longer button head bolt and the gap I have I can live with plus with paint it the gap will be smaller

The LED kit came from an Etsy seller, and features lower-brightness LEDs (for a less intense effect) and a proper black plastic switch housing (with the white “on” and “off” already painted).

I may add a resister to dim my leds and reduce the current in the circuit on mine.

So the more I look at this kit and the more I think about it I was wondering if you are like me and like being able to disassemble and reassemble things if anyone has thought of incorporating M3 nuts into this kit where possible to save wearing out the threads on the resin frame and grip frame or just for a firmer connection from outer to inner butt frame.
I have purchased some slim 1.8mm thick nuts and was thinking of drilling and countersinking them where possible or surface mount them where not visible ie internally.

Big shout out to tiptopworkshop for super fast service on some metal upgrade parts that arrived today along with some other parts from the interweb.

Received the fillister screw to replace the Weaver knob, but the diameter of the head seems a bit too small. Hmmm.

Anyone have any sources for an accurate screw?
