Post subject:	Pulse rifle build
Thought I would have a go at building a pulse rifle that had seen a bit of action from stuff I had lying around. The base for the build I had to purchase specifically, namely the Airsoft Thompson and SpaS 12, although these are reletively expensive it is hoped that the rest of the build will bring the overall cost down. This build is a kitchen table top build using the following tools: Tenon saw Hack saw Junior hack saw Mitre block Stanley knife Exacto knife/scalpel Electric hand drill Screw drivers (various) Scroll saw Elastic bands Plastic clamps Milliput body filler Hot glue gun Gorilla glue PVA glue Super glue The finished build will not be an EXACT screen copy, and some parts will be inacurate because of the stuff I have to work with. Mistakes will be NOTED and where possible alternatives offered. Also suggestions from other members will be incorporated and if not fully adopted, reasons will be given. The next two images show my build so far and the following images is the journey of how I got there. Any suggestions or queries are welcomed. More images to follow.....

First of all: Awesome. Second: is all that stuff 1:1 scale? Some of it looks very familiar (different colors though) as the airsoft bits I used to make my son's 2/3 scale pulse. Regardless, back to point one, this is cool and I love these builds.

It was a bit slap dash (figuring the 4 year old wouldn't mind the weak points and the grownups weren't going to scrutinize it! )

Post subject:	Re: Pulse rifle build
Yes it is 1:1 scale, I have a bit of sanding to do on the orange Thompson body which I had overlooked in my previous post, however I will do a complete breakdown on all the individual parts c/w images if it will help others with their own builds. The Thompson and Franchi SpaS are, as rightly identified as (sprung) airsoft weapons, the sliding breach block is wood with a layer of steel from an old PC case and part of a UK coaxial connector, barrels are PVC plumbing pipe. The PR's shroud wil be made from 5mm and 3mm thickness ABS plastic sheet. I hasten to add that this build is a kitchen table top build and most ofthe shaping work has been done using body filler, a dremmel, hack saw, and various grades of sand paper and a 12" mini scroll saw. It is by no stretch of the imagination going to be an exact perfect replica. Watch this space...........more to follow. Transmission terminated.

Looking good so far! Where did you get the spas 12 and thompson?

Author:	UK_Jackson [ Sun Mar 11, 2018 5:10 am ]
Post subject:	Re: Pulse rifle build
Both the Thompson and the SpaS were bought new from https://bbguns4less.co.uk/ although I do believe that there is a 'Halloween 1930's gangster costume' that has a Thompson that will suffice but I had no luck in sourcing the stick magazined version on its own, as most of them come with a drum that is moulded in and I am too lazy to prat about with that modification. The Thompson was just under £30.00 GBP and the SpaS was more expensive (a better quality weapon) but I could not find anything cheaper. The ABS plastic sheeting I bought off Ebay and it is worth taking the time to find the cheapest prices. https://bbguns4less.co.uk/ is also where I bought my Snow Wolf M41A PR from, and they dispatch very very quickly. Further transmissions to follow. Transmission terminated.

Post subject:	Re: Pulse rifle build Step-by-step #1
As promised, step by step build of Thompson. Image Heavy. 1) The Box Attachment: The box 20180311_052044.jpg [ 82.92 KiB \| Viewed 8859 times ] 2) Remove all external parts and barrel removal Attachment: Disassembly and barrel removal 20180311_052223.jpg [ 83.58 KiB \| Viewed 8859 times ] 3) I used a dermmel fitted with a small sanding drum to create the ejection port (approx 45 degree angle to main body) and using small piece of 21.5 mm PVC plumbing pipe on inside of Right side of body used filler to shape ejection port so that there is no gap between body and barrel. Then re-shaped using dremmel. Attachment: Creating ejection port 20180311_052325.jpg [ 119.06 KiB \| Viewed 8859 times ] 4) After marking the location of the Sliding Breach Aperture I again used dremmel to sand the opening (a steady hand is needed as dremmel tends to wander (see front of slot as mine drifted up slightly)), finish using sand paper or wet and dry. Attachment: Cutting the Sliding Breach aperture 20180311_052336.jpg [ 124.29 KiB \| Viewed 8859 times ] 5) I used 21.5mm uPVC plumbing pipe for main barrel, this needs to be slotted to accommodate forward joining screw and long enough to reach first bulk head (again using the trusty dremmel). Some of the internal supports need to be removed so barrel will slide freely up to bulk head (only remove what needs removing). Pack both halves with filler, and lube the top of the filler then clamp both sides together, lube the slotted end of barrel and insert. Leave to cure. Remove barrel and separate halves. Thus a smooth home is formed for the barrel. Attachment: Slotted barrel 20180311_052517.jpg [ 111.9 KiB \| Viewed 8859 times ]

6) Inside the Left side I glued a 5mm thick piece of smooth plastic, this not only forms a base for filling the original bolt slide slot but will be the back stop for the new breach block. Attachment: Breach block back stop 20180311_052555.jpg [ 133.03 KiB \| Viewed 8857 times ] 7) Another piece of the 5mm plastic acts as a bottom guide to the new breach block and the black object encased in filler on the left of the image is a rubber grommet to act as damper for the breach block to prevent damage to the internal structures.

The metal is cut from an old P.C. hard drive shell and the bolt is part of a UK co-axial connector. Attachment: Shaped wood 20180311_052931.jpg [ 90.75 KiB \| Viewed 8857 times ] 10) Add the spring to the bottom of the breech block and the screw on the leading edge lines up to meet the grommet on the inside Right half.

11) Fitting the breech block. Fit end of the spring over the internal screw post and place sliding block in position. Attachment: Fitting sliding breech 20180311_053416.jpg [ 148.77 KiB \| Viewed 8857 times ] 12) Re-fit original magazine lock and trigger mechanisms Attachment: Re-fit mag lock and trigger mechanisms 20180311_053604.jpg [ 147.24 KiB \| Viewed 8857 times ] 13) Re-join the two halves Attachment: Join the two halves 20180311_053654.jpg [ 105.18 KiB \| Viewed 8857 times ] 14) Check that the bolt is free to move back and the spring does not snag on return stroke Attachment: Check bolt is free to move 20180311_053716.jpg [ 130.73 KiB \| Viewed 8857 times ] 15) Insert barrel Attachment: Insert barrel 20180311_053753.jpg [ 114.95 KiB \| Viewed 8857 times ] 16) Assembled Please NOTE: Do not fasten together at this point as further work is still required to fit the stock. Hope this is of some use to someone.......... SpaS and shroud builds to follow Transmission terminated

Before you go much further with the build, have you seen this kit? (also posted about this in the Readyline forum, you need to have a FB account to view this). https://www.facebook.com/trooperamp/pos ... nref=story Its still being developed, so they have yet to work out a price, but just something to consider.

Cheers SimonT, that would round off the build perfectly.

Just so you know, those airsoft guns are definitely under sized (not too far off though) but luckily they are relatively well scaled to each other so won't look stupid. Great build so far mate
