I cant get a chance to return on this until after the weekend.
for chicopee (Mechanical): sorry, as we all know this medium can at times be confusing or maybe it just me :) yes it is just me :) There is no overhead crane involved.
The equipment is actually a telescopic column section with a...
Thanks everyone.
This is for 3DDave (Aerospace)
The equipment does crane up and down so the Centre of gravity does fluctuate through using the equipment. What I am trying to do is extend the height range.
So assuming no tipping (stability) with a load at the maximum height. If I increase...
Sorry In talking stability here I am not talking about the shape size or strength here all this is all assumed.
I am merely trying to convey to stop the unit from falling (or tipping) over due to its own defined footprint as we increase the height of centre of gravity by extending the load...
Hi folks, unsure if this is the correct forum.
We have a piece of equipment that accepts a load 158 kg max..
The equipment has a footprint area and a maximum height at which the load is placed upon. i.e. used in its accepted way the unit is stable.
Question. If we were to move the weight...
Hi there my apologies. It was for a camera carbon fibre tripod.
After contacting the manufacturer they said they cut off the ofending part and reglued it again with loctite 480.
A change of question but would anyone know a chemical that could weaken the bond with loctite 480.
thanks

you can thank our european cousins for this , years ago I remember you had press fits, interference, running and sliding fits.. things used to be easier :P
possibly late but
A clinch nit is a rivet with an inside thread
or simply grind down the helicoil before you insert it buy a 1D and take off approx just over half the lenght from the non tanged side
to be fair it looks simple, I presume it is not motorised? you are simply rotating a balanced load at no speed
Get the machinist to mill you a block for the bearing and turn a spigot to connect both.
Also using aluminium and stainless steel together in un-ideal conditions can cause corrosion
yeah the rollers are encapsulated in the metal housing near the end, 3 off finely set, as they will stop the carbon fibre pole from turning about its centre as it is wound in and out, and if you set them too heavy you can hear them running from the microphone.
When you say electrical noise what...
Thanks pat, appreciated
here is my drawing, my apologies I cant get to Autocad at the minute.

Hi all, my appologies if this is not the correct place for this.
Can anyone help here.
in regards bushing for a roller what would give the lowest sound transfer. Delrin or Brass with a concave profile running on 2 steel screws with a convex profile.
Loading etc is not required here sound...
Thankyou gents you have gave me something to consider.
I was emailed yesterday by one of the users who reported that it was used outside, wind and rain etc and all was fine.
we are currently making a new insert so will adjust the tolerances based on the info given
thanks again
Hi there
to Desert fox - only normal temperature differences nothing extreeme in any way. it will be getting used outside in the wet
to hydtools - well that is the multi million dollar question, I think yes, but getting someone to admit what they done.
to oldhydroman - thats what i am keen...
My appologies here is a very rough sketch if you rotate the view anticlockwise you have it.http://files.engineering.com/getfile.aspx?folder=cfa52677-3adb-4c23-b2d5-d05ab7baaf45&file=mods.pdf
Hi gents wondering if anyone can help please.
I have a ground steel SKF bearing shaft O.D. 25mm diam.
passing through a small Nylon 66/ MoS2 filled shaft I.D. 25mm O.D. 30mm. this was all machined and slid no problems in the machine shop with no lateral play.
We have a triangular JIB...
