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.
