Harrison L5 rescue

Hi Bill , I took the photo of the washer without thinking really and it was just 'staged' to show the washer idea, I did have them the right way around when I actually welded them.
You are right when you actually want to weld one cut the end off a bolt and wind a nut onto it, then as you say stick the rough cut off end through the washer and panel, then adjust the nut so the studs cut end just sticks through flush, while holding it up tight and square give it a little tack weld then leave go and weld around the stud :thumbup:.
I only had one washer so had to take apart with pliers as it was hot to do the next one, if you had a few washers it would be quicker doing a few tacks then welding them up one after another. Bill when you say gravity will hold the thing in place on the bench , it would but you would then have to weld them upside down doing it that way. The nut is not holding anything its just acting as a depth stop and also keeps your stud nice and square , once you push it against the backside of the panel, I would do them like in photo three pushing the stud up till tacked, this way your weld pool around the stud is much easier to do as you are welding with gravity on your side :thumbup:
The other thing I forgot to mention is the panel you are welding has to be about 2mm thick really if its too thin the weld will probably crack when you tighten the nut on the final job.
If you take your time and grind/ sand flush or even fill the ground off area you can hold things together with no visible fixings :D
Cheers Mick.

Hi Mick,
Yep that’s all clear now. But gravity – With stud through hole and splash guard on top, all on bench, so the splash guard is holding the stud in position onto bench top.
It’s a great tip, thanks. :headbang:
Real great job you are making of the L5, be better than new with the personalised parts. :bugeye:
Cheers Bill

Mick,
If you need any help with inverters/converters etc just shout. It is one of my (few?) areas of expertise. I've normally got quality used inverters on the shelf and help with programming etc at sensible prices.

Thanks for that offer Bob , I might just give you a shout as have a few inverters to fit on things so will see how I go and if what I have will do the jobs intended.
Some more progress on the lathe cabinet to report. I decided that the plywood idea for shelf was not needed as the cabinet was not as tricky a shape as I first thought. I marked out on some 3mm galv plate I had lying about and cut it out with the plasma cutter, its single phase weldspares 3500 and 'meant' to cut up to 10mm :lol: it only just does the 3mm really, anyway got the two shelves and the door cut out then cleaned the cut edges up with grinder and file.
The bottom shelf fitted , I welded two posts to the center of the cabinet base so the shelf wont sag under weight and made the front edge level so chucks can be slid out without lifting over a lip.
Second shelf also welded in this one has angle iron cleats welded to the sides and back and a 10mm x 40mm strengthening brace under the front set back a bit.
The hinges for the door are from RS components, I have used them before , they come in four sizes this is the third biggest 16mm diameter and 80mm long, they weld on and have a brass washer and fixed pin in lower section and once welded on the door can be lifted off in need be.
I used magnetic blocks to get the door held in the right spot, then just hold the hinges where you want then and tack weld, the tacks are enough to be able to try the door just to double check it swings open ok.
Then welded the hinges paying attention to do the bottom section of hinge to cabinet and top section to door lol, it would be easy to loose concentration and wed to both on the same section of hinge !
The fitted door closed, just the handle /catch to do will have to see whats lying around.
The door open , lots more room to store stuff now :thumbup:
Cheers Mick.

Nice 1 Mick, looks just right. There is a bit of wasted space even when the switchgear is there I guess.
