diy anons i present you with a small problem. im trying to use this 4mm thick, metal pipe clamp as an lnb holder for my satellite dish. the internal diameter of this clamp is 60mm, while the lnb is only 40mm, so it can't be fitted secured around the lnb.

there are two methods that i thought of:
one: is wrapping something around the lnb (leather or felt) to make it thicker,
or two: drill into the top metal plate and use an m6 or m8 bolt and a set of nuts to press onto the lnb from the top at the risk of breaking it. maybe i could add a smoother cap nut but it would reduce friction.

is there a better way?

Use a 40mm pipe clamp. lmao
>>
>>3004632
these are the ones i have anon. the true solution would be to source proper lnb holders from china, but i don't want to order when i can just ....

>>3004633
Post a pic of the dish, lnb, and pipe.

i drilled 8mm holes into the top bracket. so now i can use a bolt and nut to tighten the lnb. here's a picture of the felt rings i made also.

im still curious to cleaner alternatives or how /diy/ would do it.

>>3004635
why?
>>
>>3004656
>how DIY would do
Literally buy a size that fits as you're paying more for a shittier result.
>if somehow not possible
do as you did ajd piss with the cock you have. Slit PVC pipe to make adaptors, wrap electrical tape, squeeze some chicken necks in there, old socks you're too lazy to wash, drive in wedges...???

Buy a 60mm lnb

A cock clamp?

>>3004629
You can fill it with epdm or HDPE pipe layers but I wouldn't do either for a permanent install, just get a 40mm size, they cost like $2-3 each and any hardware store stocks them.

already done that with previous lnb holders to elevate the height to the sweet spot.

>>3004664
they don't make 'em 60mm. at least i don't think.

>>3004666
>lathe go brrrrrr
i had my hand inside the clamp, so it was trapped nicely in there while drilling from the outside, and the drill bit reached the point when the teeth were starting to latch onto the sides of the hole, turning the bit into a screw propeller, and driving the entire drill and bit towards the center of my ring finger knuckle. it left a nice bruised dip as a reminder, but another half second with the trigger pressed and i could've lost the tip of my finger.
my point is, i'd probably die with a lathe.

>>3004670
now you're giving me ideas.

>>3004629
just cut a piece of rubber from an old car tyre and wrap it around to compensate for these 2cm you lack (in your pants as well)
if someone asks why there's rubber bushing you tell them it's there so it doesn't squeak and to damp vibrations

3d printed ring would have taken you almost no time at all, and it would be rigid.

my what has what?
the channel leases its past midnight runtime to adult chat services. they broadcast softcore pawn and 0900 numbers 5 hours a night, even though it's a FTA channel, i don't really watch smut that way, but you can imagine my surprise the first time seeing eva notty on the literal sports channel.

i haven't encountered ANY OTHER channel that does this so far, and honestly I'm curious if they even exist. sat forums are mostly dead so it's pointless to ask there.

you don't need to own a car to get a car tyre
people throw them away all the time, everywhere

Just cut shims out of a milk jug or something
>>
>>3004656
just put 2 bolts in the ring with the pipe
>>
i had a similar situation today mounting 3/4 cpvc with 3/4 galvy 'raised' clamps
i just cut some rubber toilet shims to the shape of the bracket and tightened it down
worked perfect :)
>>
>>3004629
Get rubber hose with inside diameter about or a little less than outside diameter of your pipe, cut it to a length about as tall as your clamp and spkit down one side. Slip it around your pipe and then put the clamp on. Instant custom rubber shim.

>Get rubber hose with inside diameter about or a little less than outside diameter of your pipe
wouldn't it make more sense to split a rubber hose along its length, and wrap it around the lnb? since that way: a) you can loop it as many times as necessary, b) you wouldn't need to steal a 2" water hose from a fire truck.

>>3005323
> toilet shims
did you also glue it? because they might fall out of the ring. also why do toilet shims even exist?

>>3005307
i already drilled a hole for that exact purpose, i should've drilled 3 holes to fine-tune where the lnb sits inside the ring (for better reception)
>>

Who doesnt own a fucking 3d printer?
They were selling enders for $99 almost a decade ago, even Aldis had them on store shelves.
Actually kind of sad you dont have one, and are pretending its some sort of out of reach item.

me. and i do more 3d modeling than you do. people don't share the same interests is all.

anyone know how much of the lnb front ring / ridges i can saw off before it affects reception. im trying to make it smaller for a tighter fit between an array of lnbs.

they're not falling out of a clamp
>why do toilet shims even exist?
floors are usually poured, leveled, and installed by spics and rarely are level
a toilet is formed ina... brb gonna research this...
ok like I thought, they're formed in molds and generally well leveled at the base
being it's a rigid structure, gaps around the base will cause rocking or at the worst cracking
generally you hand tighten the bolts and shove them around looking for gaps
>gap
>put shims as far as can go
>finish tightening down, cut excess, caulk, wa-la

>>3004656
I would reduce the inner diameter by modifying the clamp. It would include a vise, some heat, a hammer, quenching oil, etc. But I think leather/PVC spacers will do it if I'm not bothered to do so much work.
>>
>>3004629
I wrench anything from aircraft on down, weld and have a home machine shop.

Many years ago I got some great advice from my (retired rich and still gets money from selling his machine shop, which is in a highly competitive business):

Don't waste valuable effort making what you can buy at trivial cost, or buy a thing closer to what you want at trivial cost.

Use Google Lens or whatever to hunt the clamp you want or something very close. You will learn the highly useful skill of how to search for parts!

That's more complex than it seems even with AI, and is a key reason I did so well running military and civilian tool rooms. The tool and equipment-fu has real power.
>>
>>3005926
Absolutely! I do electronics repair as a hobby, so I'm used to hunting for parts, reading through datasheets, and looking for matching alternatives for the part i need (transistors, regulators.. etc) to fix the thing.
My problem however is lack of availability, and I hate the return / re-order process so much. In this case, drilling through it achieved the desired result.
>>
>>3005654
yeah let me fire up my 50k$/year copy of ansys and model a feed horn based on this picture alone.
they wouldn't be on something mass produced unless they were necessary. however, necessary for everyone doesn't necessarily mean necessary for you, if you are in a good signal area and clear of outside interference you might get away with cutting a little, but as well as rejection it also is for matching the different down freq. so again, depends on what channels you want to catch.

if you can afford it, then maybe try it slowly and check what it looks like under heavy rain fade.
>>
>>3005972
i didn't cut the radial pegs, but instead removed the outer wall around them (exposing the pegs without an outer wall) = 0% signal quality and a ruined lnb. i bought this to experiment with in the first place, but sad to learn it this way.
