New Linear Machine

[fyxation]

here is a new rotary ive been working on this week, i used a bearing from a direct drive canister type machine to push the piston, i also mounted the frame on an eikon spring for a bit of give, so far so good!

Wow, that's certainly different... I like it!

[Zapp]

WOW,looks a bit weird and more complicate than it is !
But i like it !
What is the weight of the machine ?

[fyxation]

hey thanks guys! weird is good! this machine weighs slightly less than my neo tat, so around 6.5 oz

Well thaught out! it seems you have taken the best of everthing and came up with a workable machine! I see you would have give in 3 areas-the connecting rod gromment,the a bar area, and the coil spring on the bottom, cool because i could see the bottom spring prob arching back at an angle like a coil machine,that combined with the other give area msut feel pretty close to coils.

Oddities of badassness! Try an O-ring under the front sprint screw (does it "bounce")

[fyxation]

haha! thanks, the o-ring is a great idea! this machine actually has 2 points of give, a very small amount in the connecting rod grommet and the rest is in the spring between the frame and vice, unlike my other linear mod where all the give was in the a-bar by not directly attaching the connecting rod to the a-bar piston, relying on a coil spring for give on the down stroke

[Rattus]

Going by the pic, it seems like there would be a bit of a bounce and clacking (like a-bar > coil top) causing a bit of vibrations that you may not want. The O-ring cushion might help that and change the give a bit too.

hey i used a 22ga spring on it which is really stiff, and actually there is no clacking or bounce, but i will try the o-ring idea to see if there is a difference

Investing in a thread tap and the drill bits to go with it will help to remove some of the extra bolts you need to put on everything. also helps if you have a drill press to keep it all aligned when tapping your threads.
