Forgebear Recoil unit
Anyone have any experience with his 3D printed unit? How big is it?

Re: Forgebear Recoil unit
If you want information about the recoil unit, the best person to ask is forgebear himself. You will struggle to find a more helpful persos.

There are images regarding the size comparisons... (Stolen from Can-AM RC Tank Club forum...)

The universal version by JCC is finishing trials and getting tweaked for final production...

Re: Forgebear Recoil unit
How do you remove the barrel from the mantlet? Is is friction, or glue?
Re: Forgebear Recoil unit
For which unit?
JP? Unscrew the muzzle brake, unscrew the mantlet (2 screws in bottom of the mantlet retainer) and exterior mantlet can be pulled off the mantlet retainer.
Then pull whole recoil/barrel assembly out from inside.
I HATE the JP mantlet system so I designed and made a friction fit exterior one. It is very fragile when converting to a recoil unit (Cutting out for barrel clearance....)

Pershing
Re: Forgebear Recoil unit
So the Pershing is akin to the Bulldog... The plastic barrel is molded into/glued to the mantlet. The aluminum airsoft tube is inside this plastic sleeve.
Had to cut off the plastic barrel at the mantlet front (Actually flush with the main front of the mantlet to allow excess barrel length to be shaved down and to recoil inside the brass tube.
Aluminum airsoft tube is CA'd into the JCC Recoil unit. Note the heavy sanded area of the plastic barrel and the gap between the plastic barrel and the recoil unit barrel mount.
Obviously with the plastic barrel's fume extractor and muzzle brake it cannot be removed by sliding it through the mantlet towards the recoil unit.
A small 2mm screw is threaded in the underside of the barrel to secure the plastic barrel onto the airsoft tube. This also ensures proper muzzle brake clocking/orientation.
Need to remove? Remove the retaining screw and slide the plastic barrel off.
Showing the 16mm OD x 14mm ID brass tube used as the gun barrel sleeve for recoiling. Heavily epoxied into place for strength.
I also epoxied the mantlet into a permanent mount on the recoil unit since there is clearance. Next will be the 7mm OD x 5mm ID brass tube mounted for the IR emitter.

Re: Forgebear Recoil unit
Great thread. Didn't know about the units bust ordered two of the cimpact version. That is exactly what I needed.

One note on the JCC Compact recoil unit. They do not work with stock rotating side elevation units (Stug, Sherman, Panther, etc...). You will need to use the servo tail and individually tailor the linkage/throw to get the desired gun barrel elevation/depression.
The new prototype of the JCC Universal (shown being part of the M41 above, and the design models above) will work with those elevation units.
Re: Forgebear Recoil unit
Thank you. I already have a servo elevattion mounted and plan to just glue or screw this unit to the mantlet directly.
