Thread: Bueller's shed - a noobs journey through vintage machinery

Yeah I need to get some earmuffs that don’t go over the head, the only thing I usually need them for is angle grinding and for that I’m wearing a face shield which gets in the way of normal ear protection. Should probably look into that this weekend!

The "around the neck" Peltors clip over the back of most face shields including the Armadillo - the muff hold the shield down and the shield stops the muffs from falling off.

I’m very happy with my REPTILERS. The positive, in addition to the lack of a headband, are the deep goggles which fit comfortably over my glasses.

Cheers guys! Both great suggestions, I’ll likely get a pair of both. The reptilers will be good for my old man, he wears glasses so they look perfect.

Thanks Fletty. Got to get a pair of those. Solves what irks me the most about separate eye and hearing protection.

Australian Wood Review (AWR) were selling them for a while AND my pair were a ‘gift’ for signing up to a 1 year (I think?) subscription. I don’t know if they are still doing it?
In addition to being very handy in the shed, I also wear them when mowing etc because they don’t interfere with a hat.

The main issue I have with eye muffs is that they don't protect the the whole face which is really important in for example most grinding situations.
The other is that the plastic glasses won't provide sufficient pressure around the ears to seal off the sound from getting through the hair gap. I note the bloke in the Youtube clip is bald so for him they will be OK.
3M Muffs use a very stiff SS wire to generate a relatively high side pressure to get around this problem although this can then be a problem for some wearers when the muffs are worn for long periods but that is what is needed to reach their DB rating.

Gave the thicknesser a test run, need to play around with the height of the infeed and outfeed rollers but very happy overall! Leaves a great finish, noise levels are much lower and the 4” dust outlet seems to be coping just fine using a 6” > 4” reducer.

Also had this fella wander in to see what all the racket was!

Is that based on fact or supposition?

They meet the same Australian Standard as 3M units and nowhere does it state that they only meet this standard if the wearer is bald

I didn't try too hard but I could not find a complete sound reduction spectrum performance such as is provided by 3M products and should be freely available (see below).
For highest level protection I would only buy from a supplier that could provide this spectrum.

While the AS standard supposedly takes, experience in fitting ear protection devices, and hair and optical wear into account a few years back I read an scientific article written by audiologists that claim no matter what the muffs are made of a high side pressure is essential to get class 5 level performance from ear muffs. If that level of side pressure is not there then class 5 might be achieved in testing but not in practice. The AS standard recommends the following be supplied to the purchaser of ear muffs.
Manufacturers and suppliers of hearing protectors must ensure that all purchasers are provided with information thatwill enable the protectors to be used in a safe and proper manner.
The following information must be provided in or on the package in which the protector is supplied:

• The method of adjusting and fitting the protector
  
• Instructions for cleaning and disinfecting the protector, if appropriate
  
• Maintenance requirements, if appropriate
  
• List of spare parts available for replacing worn or damaged components
  
• Mass of the protector (Earmuffs)
  
• Clamping force (Earmuffs & Ear Canal Caps)
  
• Notes warning about the effects of wear and tear and the effects of other items impairing seals
  
• Details of the mean, standard deviation and mean-minus-standard deviation attenuations.(these must bedisplayed so that they can be viewed without opening the package)
  
• A label showing the Class of the hearing protector
  
• Information provided by a manufacturer or supplier of hearing protectors must be consistent with the hierarchy of the control of noise as required by the Act.

For anyone that has a Reptiler I would be interested to see the information above in bold.

Thanks

I have and very happily use Reptilers on a reasonably full head of hair and I quote....

The Eyemuffs are certified to AS/NZS 1337.1 and 1270 ID: 3571.

Decibel rating Class 4 Tested to AS/NZS 1270, can be used in noise up to 105dB. Safety lens tested to AS/NZS 1337.1 for medium impact.

4221EF23-69CD-4E38-AE78-666E720BB6CE.png

Australian Standards have very strict guidelines for product certification and it’s illegally to use the Australian Standards logo and information for a product that has not been certified.

The manufacturer of the Eyemuffs has complied to all the requirements for the Eyemuffs to be certified to AS/NZS 1337.1 and 1270.

Thanks fletty that's good to know
It's interesting to see yours are rated to class 4 but the All Safe website is claiming the Reptilers are class 5?
Maybe they have released a new model?

My question would then be why don't they like 3M show their data on their website.
My first take of the reptiler website was that it looks a bit amateurish and like they are more focussed on supplying a range of exciting colours than a serious product.

I looked up the sideways clamping force of the Peltor H10A and see they have a clamping force of 10.3N which is consistent with what I measured.
The 10B (behind the neck model) is 11.2N with the increased force needed because it is a longer band and needs the extra pressure to meet the Class 5 rating.
The X series Peltors have even higher pressures in the 11-12 range.

Maybe I'm overly cautious but I do wonder about the long term elasticity performance of plastic versus spring steel.

Thanks Fletty. Mine arrived this afternoon and I was signing in to put in the specs. BobL asked for and saw your post.
Nice unit; fits well and feels comfortable. Nice to be able to fit the specs in under the safety glasses.
Like BobL said, their site is not real flash and the specs. would be nice to see before hand but their product is great. It’s also nice that all parts are replaceable.

I also like the fact that they are Australian made and that, on Amazon, they are advertised as such. It’s probably part of Amazons strategy to enter Australia directly. I must check if they also note MagSwitch as Australian?
I’m going to get a green pair with ‘yellow’ lenses for next Australia Day

PS, sorry for the hijack Bueller
