Which Comatic base is small enough to mount to KF700 flip-away bracket
|
Subject kinda says is all but,
?
I just discovered the smart stand that came with my Comatic DS700 is too wide to mount to the flip away bracket. ?The hole pattern is fine but the flange at the base is roughly 6.7¡± wide whereas the usable width of the bracket (without running into the strut support) is around 5¡±.
?
Has anyone successfully mounted a recent Comatic power feeder to a Felder flip-away bracket. ?If so can you provide details on the stand from Comatic?
?
Regards,

¿ªÔÆÌåÓýHi Ron,Smartstand has a bit of a history. I have it on my Dual 51 and built a custom bracket for it. Earlier we weren¡¯t sure if it is advisable to even mount a SS on Flip bracket. I did a whole study to determine weight difference of SS compared to traditional Felder stand. SS with either a DS300 or DS400 was 15# heavier than Felder stand / Vario4 combo that I have on my flip bracket of KF700. Since then people have mounted them on the flip bracket. One member cut the sides of the round base of SS so that it does not stick past the bracket top. The key danger is to possibly forget to or not tighten the horizontal tube enough and cause to bend or break the memo pin. I would always have the horizontal arm such that it moves away from the memo pin during flipping of the tilt bracket. I assume you bracket has the gas assist, it would be dangerous to handle it unless you are built for it.

Another way to do that is a simple interface plate with the hole pattern for the smart stand and the tilt bracket.?
?

The danger Imran describes is real: the whole top of my smart stand came off once into my arms when I had not tightened the top before flipping.? That thing is heavy and I nearly dropped the arm and feeder.? I modified the smart stand afterwards to prevent that from happening again.? So while I am happy with the smart stand I would not recommend it for use with the flip bracket.? |

Could you share your safety mod ?
?
Given the width of the standard Comatic stand is 5.5¡± vs the 5¡± usable width of the flip stand with gas strut I¡¯m faced with trimming either one - though I was thinking about an adapter like above.?
I was also contemplating modifying the gas strut support arm to offset it further to the left to get the clearance I need. The existing hole pattern works if you can just center the base on the bracket. Seems there is enough slop in the retaining pins and brackets (top and bottom) to allow for this. ?I wonder if anyone else has considered this approach.?

I think offsetting the support arm would work as well, it's only a 1/4in after all.? You have a little misalignment with the bottom attachment point but it does not look like enough to bother with.
?
I machined a groove into the top of the vertical column and placed an M6 bolt with the end turned down to 5mm into the casting.? That way the top can rotate but not come off?unexpectedly.

Hi Ron,
?
I encountered the same problem when installing the smart stand on the tilt bracket on my KF700SP. ?I didn't want to grind away part of the stand base, so I made a shim to offset the assist cylinder bracket enough to enable the smart stand to bolt up to the stand.
?
I made my shim out of steel. ?However, I am sure a piece of aluminum would have worked OK. ?It took an hour to map the holes, drill and tap the appropriate holes, and install the bracket.
?
See photos. Good luck.
