Small metal airsoft part

[dazza]

Im a little too busy but having a quick look at the original part below and with them being plastic is the gusset that reinforces that pin/upright needed?im not sure what kind of stresses it will be under but if it were made in aluminium??..could the upright be replaced with a brass pin or cut down stainless bolt so made in two parts or does it need to be square and shamfered like you drawn. it seems a simple part to make out of a bit of plate or billet and like said a bit of a file where needed using the old one as a template seeing as its a one off.

Ok the part model is now revised, see the files attached to this post.

Changes from the Mk1 to the Mk2:

• area beneath the lever arm removed due to a clash with part of the hop unit (the part that this arm is fixed within)
• Nub effector (lowest part) raised by 1mm to move the "Sweet spot" of adjustment closer to the centre of adjustment, giving a greater range of adjustability
• Pin Hole enlarged slightly to make installation easier and movement less restricted (also rounded the internal face as sketchup can't do curves properly)
• Lever arm reduced in size to correct a fundamental error made with the Mk1 (my bad :P)

All these corrections should make the part just slip in nicely and work a dream.

If anyone needs any help with the part, or another file type creating, just PM me on here

Hi there.

Just to double check, is this the hop up arm for the ICS L85/L86? If so I am very interested in a metal one as the plastic one is not great. Is it possible someone could make one for me, name a price though first!

Thanks.

[TheGrover]

yes, this is designed for my ICS L85 (I assume that the L86 has the same hop unit, though i haven't checked).

if you do want one, make sure that you use the revised model, attached to the post above yours, as the first version was a pain to install due to my own stupidity (I had to take a Dremel to it).

its also worth saying that since i have changed the model after installing mine, i haven't actually tested the updated version, so be prepared to "Adjust" it, if necessary, though i hope you shouldn't need to.

Does it have to be that exact shape? What are critical dimensions to fit/work? As shown I think I would start with a solid lump of Ali, take 3 or 4 cuts on different axes to get the major shape after drilling the holes needed, then get to work with a file.

Don't see the problem using TIG, I was using it on 1mm plate every time the MOT came up on my Metro

[TheGrover]

none of those dimensions are critical, certainly not as critical as i have made out with the 0.01mm dimensions.

and the part is really a copy of the plastic one, the reinforcement of the protrusion will probably not be necessary. the stress involved in the part is a small spring pushing the end furthest from the protrusion upwards, turning the arm around the pin and making the lowest part push a small nub into the barrel of the gun, giving the BBs backspin the protrusion extends onto an adjustment wheel which is turned to lift the nub (against the spring) and reduce the backspin.

does anyone think they could make this for me?


Thanks

Yep I can and you where in luck today as I had to setup a machine so you gave me something to do. Here it is.! Pm me your address and I'll send it you.

Only differences are there are some 1.5mm radius in corners as smallest endmil I had was 3mm.

[TheGrover]

That looks great, ill PM my address to you now.

How much do you want for it? Its only fair that i pay for your time and effort.
