Carl Knapp from Felder USA sent me the brilliant instruction and pictures below on how to install the gas strut, and I was done in 5 minutes!!! Felder tech from Mississauga asked me to try the ratchet strap, I simply cannot get it work.?
I do not have the F48 on the bracket. I know it would be very difficult and dangerous to have it on the bracket while installing the gas strut.
The gas strut made in Germany is rated at 1600N, no wonder I cannot push it down using my manpower :) From Carl Knapp:??loosening the bolts circled and the lower nuts, That let the bracket lift up enough to attach the shock. Then I tighten it back down.?
?
James, I had the same problem when I installed mine. I can't remember exactly what I did. I seem to recall that I left the two bottom nuts that attach the bracket down low on the side of the machine off. Then you can tilt the bracket up enough to get the pin in. Then you have some leverage to push the bracket down and install those two nuts.?
It looks like you have the stock feeder already installed on the bracket. I would remove it until you get the strut pinned and the bracket installed correctly.
I wish I could remember exactly how I did it but you don't have a defective part as I had the same issue. Just ignore the funky Felder instructions and be creative. It is doable. Brian's advice is sound also.?
Good luck, Marty
?
Back to March, I got the Felder gas spring assistance, but life gets in the way. Today, I finally have time to install it.
I have difficulty to attach the metal bracket to the head of the gas strut. See attached pictures.
I tilt the base, the gas strut is just a few millimeters longer, and I am not able to push down the gas strut using my manpower?to align the holes for the bolt connecting them together.
Any advice?
Thanks, James

I've mounted the bottom of the bracket such that I need to compress it about an inch. How much did you need to compress the felder has spring?? I'm thinking that even if I can rotate the bracket up I'll still have a problem compressing the spring enough to rotate the bracket back down. How did you do that?
|
Jeff,
I assume you are asking me.
Loosen the bolts circled and the lower nuts in the following pictures, That let the bracket lift up enough to attach the shock. Then tighten it back down. There is no need to compress the gas spring using your manpower.
After installing the gas spring, then install the power feeder.?

Hi James. I loosened the top screws and removed the bottom nuts. That's let's me tilt the bracket far enough to mount the gas spring, but I can't get the spring to compress back down so I can't get the bottom bolts back through the holes so I can't reinstall the bottom bolts. How did you compress the spring after you installed it?
|
One more point to add. I mounted the bottom bracket such that I have to compress the spring more than an inch so I need to rotate the bracket all the way off the bolts. Should I mount the bracket lower so that I have to compress the spring less?? What is the amount of compression I should need to achieve?
|
Jeff,
Are you installing the Felder Gas spring assistance for the tilt-away bracket??
If it is Felder's, loosening?the top black screws and bottom nuts (do not remove the bottom nuts) should give you enough distance to install the gas spring, then tight down the bottom nuts and top screws.

It's a big lift, the homebrew version of the felder bracket. My machine is too old for the felder version.?
I'm thinking I have the bracket too high and that my spring my by oversized. I have a 250lb force spring, but I have light weight feeder that only weighs 31 pounds (plus the weight of the post assembly).?
|
Ok. I think the bracket size, mounting position and gas spring specification are critical. That is why you will cannot attach the gas spring. You should not use manpower to install it, otherwise, something is not right.
When installing the gas spring, remove the power feeder from the tilt away bracket for safety?reasons.
James.

I used the 250lb strut, did you try to compress it with a Bessey parallel face clamp, the one that look similar to this:
Mine are older K-body clamps, but same idea. Stretch the clamp over the ends, slide it tight with the screw all the way out, then tighten as much as you can get with the travel of the screw.
As for where to mount the bottom bracket, tilt the upper portion to figure out where it’s the highest, bolt on the strut, mark the bottom bracket holes and then move up a 1/2” to 3/4” with the holes and you are good.

I moved the bracket down lower so I could easily mount the spring (only had to compress about a 32nd of an inch) just to see how it would work. For my feeder I think the spring is too powerful. I can only bring the feeder about half way down, even if pushing on it with my arms to add more force.?
?
The picture shows as far as I could push it down.??
?
?
If I get an underpowered spring, the only issue is it won't assist as much with the lift, right? I'm thinking better to error on getting a less powerful spring when I order the new one. Maybe 100lb of extension force, which it says takes 132lbs of compressive force vs 330lbs for the 250lb spring.?
|
A lot of the forces and balance depend greatly upon where you position the feeder when you are tilting it up and down. I have the smaller 3 wheel feeder, F38 and it still isn’t too powerful when I have it where it needs to be. I took a sharpie and marked alignment marks on the vertical post for rotation and the over arm tube as to where it needs to be for the best balance point. When I have it where it needs to be, the thing is fairly neutral with just a little down force required to park it in the down position.

If you have the clearance on the jointer side to position the feeder as shown below, I think you’ll find this makes raising and lowering it a lot easier.

I tried rotating it and I still can't push it all the way down.? The spring is stronger than me (and the feeder) - which either means its a strong spring or a weak me.? I'm going to buy a less powerful spring and see how that works.??

Hi David
?
I just tried installing a Comatic DS700 (smart stand) to my KF700 with the flip-away bracket.
?
The usable width on the Felder supplied flip away bracket is only around 5” while that flange at the base is 6.7” (the hole pattern is fine).
?
Kyle at shopgearinc claims the standard base is 7” wide - wider than the heavy duty smart stand.
?
Seems unlikely I’m the first to even encounter this. ?Have you run into any of this?
?
Thanks in Advance,
?

I have two of these power feeder mounts I will sell one for $ 1,100.00 us only plus shipping ups gr? Mounting base is cast-iron machine 6 in.? with 7 1/2 inches in opening Unit is 8 inches wide by 7 x 11” tall 3/8 inch or 10 mm roll plate. Screw is 1 inch or 25 mm. Hand wheel is 8 inches in diameter moves up and down like nothing. Just crank your power feeder in or out got both holes in the back of it for standoffs or mounting it however you want this is not a toy serious machine tool stuff. If you’re interested, contact me off the fog. This is what I paid for them. In 1992. Best mac

Correction from Kyle - the Comatic standard stand is 5.5” wide at the base
