    Default Another arthritis aid

    I haven't posted much up here lately so I thought it was about time.
    I had to use some Soudal T-Rex yesterday and for those who have not used it, it is quiet thick and takes a fair bit of effort on the cartridge gun handle to get it out.
    Doesn't do my arthritic hands any good at all. I have a air operated gun but the air acts by pressurising the gun body and thus pushing directly on the cartridge insert. This is ok if you are wanting to use a lot of product (ie multiple cartridges at once) but a pain if you just want a little bit.
    I mentioned it to Dave J via txt yesterday when I was still in the shed and quick as a flash he had sent me a link to a diy cart gun video. (thanks Dave)
    When I had a chance to look at the video it was pretty much what I had already thought about so today I got stuck in and modified an existing gun I had.
    Basically removed the original push bar and fitted a nutsert (after being reminded by Dave that I had one.) into the hole in the frame. (setting the nut was a hand killer as well - might have to look at some sort of power assistance for that too)
    Used a bit of 8mm thread bar. Turned the cartridge end down to 6mm and threaded. Used a couple of Nylock nuts on that end so that the steel push plate is free to turn on the thread bar. Found a bit of flat bar with a wooden handle that I have had laying around for years. It even had an 8mm hole in it in exactly the right place. Just had to cut the excess F/B off the other end.
    I haven't actually used it yet as I don't want to waste any adhesive but I'm sure it will work ok.
    This arthritis (as I'm sure a lot of others here know as well) is a bugger. I've spent a fair bit of time on and off over the last year or so extending chuck key handles and modifying bits and pieces of my machines to make it easier on my hands to use them.
    Discovered a couple of weeks ago that I can no longer tighten my 3/8 Albrecht keyless chuck tight enough by hand so have had to go back to a key chuck with extended key handles. grrrrrr.

    Nice work Bollie ( and Dave for the idea )

    Re: keyless chuck

    Would a strip wrench help with that?

    Bollie,
    You are a lifesaver mate!

    I have avoided a job that requires 10 meters or so to seal.

    Thanks to you I'll be going that route convert one of my cartridge guns.. I already have everything I need.

    Don't need to buy the tool, fastener or handle.
    Beauty!!

    Yeah. I've also got it in my feet. My most comfortable shoes are my work boots. Driving a manual car is not helping anymore, so I've bitten the bullet and treated myself to an early retirement prezzie of a new ute with auto trans. I'm a bit concerned that in four years when I'm able to access the pension I wont be able to drive.

    Not really my idea but I'm glad it can help you.

    For that much, it would be worth your while to get one of these. I'm assuming you have a compressor, https://www.gasweld.com.au/534748-toolex

    I tried that but I found it was more hassle than it was worth. If the chuck was a 1/2" then it might be worth persevering but as its only a 3/8" I cant be bothered. I'll probably put it up for sale.

    If the strip wrench happens to be a tool you can remove a vehicle oil filer,with?

    If its the same, this one has a length or rubber canvas belt which locks back on itself. Much like the material in an old anti static strap for cars.

    Yes men, it works like a charm. Had to use this on a key less chuck at school years back when a young genius ( not one of mine ) took vice grips to it.
    I had purchased my tool for vehicle oil filters. The HOD bought one for the department after the tool worked so well.

    My strap wrench is one I made 30 years ago. It uses a length of seat belt webbing so its pretty wide. I could get or make a narrower one, but since I've lengthened the handle on the chuck key its just as easy to use the Jacobs keyed chuck.

    Peter & Dave thanks top idea with the gun LOML often complains when she has to use it her arthritis and after effects of a broken wrist.
    I'm going to miss the quick release & ease of pushing the piston rod away to store it tho.

    Peter I also made a filter remover out of seatbelt & 1in tube welded a socket to the end of the tube so I could use ext bar or ratchet. Long enough to fit around bus & coach & truck filters.

    At Mudgee Feild days yrs ago picked up 3 sizes of a similar tool for Sue to use in the kitchen to open jars of Another arthritis aidAnother arthritis aidAnother arthritis aidAnother arthritis aid she still prefers bash the lid on the bench, use a knife to allow air in then a none slip mat to grip & undo.Another arthritis aid

    These would be excelent for use on chucks as only 1/2 wide strap.

    I have owned and used an air driven caulking gun and what is needed for good control is a low pressure reg not a normal one to regulate that speed of material application. A couple of PSI is most probably enough. The bigger problem is relieving the pressure to stop the material flow which is not addressed at all from what I have seen, at least in the cheap ones.

    That's exactly what I have experienced with mine.
    Ok for jobs where you are using a lot of cartridges one after the other, but not so good for a small amount.

    Just a wild thought, would it be possible to mount a tyre inflator, (one that has an air release button), so that you press the release button as you release the trigger.

    I used the modified cartridge gun this arvo. Only a small job but it worked really well and the fine control was also a lot better than I expected.
    Obviously it takes a while to wind the thread bar in and out but I can live with that. Could also stick a socket on the battery impact and run the bar in or out with that.

    Thanks for the mention Peter, and am glad it's all worked out.
    Like I said in the text, I forget I have a 1400pc nutsert kit often, and use a different method.

    The pop rivet type tool they give you is totally useless unless you installing M8 aluminium ones or M6 steel ones max, then you need a stronger tool, or better yet a battery drill adaptor at $100, which is worth more than the whole kit, lol

    All right if you're doing it daily, but for something you only use every few years it's expensive to have sitting there.
