    Seemed like a great day for a bit of outdoor MIG today, nice n dry, gentle winds

    So thought I'd make a little progress on workbench for shed, this has been welded with Arc til today

    Photo below is how project left as i knocked off for the day

    Overall so far I'm happier with the Arc welds ive done. Not that they are great, just that they are more consistent to each other and I'm confident with them

    The MIG welds kept catching me out, do a couple I'd accept for what the project is....then rubbish to be polite

    Obviously I'm learning and will persevere, but did as many mistakes on the flat as i did vertical, which to me is odd :doh:

    Think i need to finesse wire feed speed a little more, will get there

    Do love the speed of progress with MIG tho, no chipping etc, and tacks super fast to do

    Going to finish this bench with MIG only, practice only way to learn eh !

    Need another horizontal brace on leg pair at far end and considering 2 lengthwise braces between the two sets of legs

    That said its already sturdy, especially compared to battered wood bench i built it on

    If i get drunk in the week will share dogs mess welds from today :laughing:

    Looks good to me. What size box section did you use; will give me an idea of what the one I'm planning to do might look like?

    Hi lads

    Its 25mmx25mmx3mm box. Its just over 6ft long and 21inchs wide. Height 38 inches? Forgot lol.

    Far legs are a little bowed, thats why i plan the extra brace mentioned. Same thing happened to near legs before second brace.

    Not that it shows in photo, but top bows a little too on outside edge of each pair of legs. Tried to minimise distortion but hey ho

    For top i plan to make a laminated wood top, probably CLS timber from b&q, cheap n cheerful

    My wooden bench that lived outside for a few years and had a hard life same top. Still doing ok

    Its strong but this bench wont be used for anything very heavy, definitely nothing like an engine

    Appreciate the link tho gaz1, will have a look

    I'll post more photo's as i go on. Need to get a move on as its now outside til placed in shed

    Looking good, can’t comment on weld quality or technique as I’m only a novice with the welder

    But, if that was my frame, I’d put some feet on those legs, prevent them from biting into the floor substrate if your giving it any welly on the surface. Appropriate size and thickness washers might be ideal, think penny washers or similar. You may already be planning this

    Yes, its getting feet, they will be used to fasten bench to wooden floor of shed

    The top of frame will be fitted with flat bar cross braces and flat bar corner diagonal pieces

    These will be drilled and used to screw top down on the frame. I'll post pics when done

    And the horizontal braces on each pair of legs will support shelving

    If i cant suss these box section calculators I'll resort to destructive testing :scared:

    I'll stand on the finished bench and jump up n down a while. If it can take that it'll do, I'm not light :whistle:

    I plan to use 40mm, had to Google if that was up to an inch lol, pathetic I know.

    Looks like I should be good with that, my frame will probably be similar to OP's although want to make it extra strong in case someone uses it as a step to reach things in roof of garage, etc.

    That's what I plan to do, so I can fasten a piece of worktop from underneath, not screws visible on the top working surface.

    That'll be good and strong Yamhon

    Only reason i went for 25mm box section is price. Can currently get slightly rustry but new at £13 for 7.6 metres

    Add a £1 for two cuts and it fits in a focus, happy days

    Going to use same stuff for a couple of gates, metal frames, wooden inserts

    Well I can't afford to invest in any materials yet; but I have a few projects I'm planning that can use 40mm x 3mm box so I figure I'll order a decent amount of the same; hopefully will be able to order enough lengths of the same size at a time to get a discount price.

    Yes, place nearest me has £30 minimum order which isn't a problem but i only buy as i need

    I've never had it delivered, cutting far cheaper and car old anyway so dont mind collection

    Spotted a national steel supplier on a thread here, F Brundle?

    Might be worth checking their site for what your after

    Yup that's how I plan to go with.

    Need to pay up for a gas cylinder first, not sure if that'll happen before my holiday next month.

    It can add up can't it, but you'll still be quids in compared to buying benches like that ready made

    In long run reckon welding pays for itself for me with savings I've made, hope others find the same

    Best go, work tmw

    Always a good test, but I’d put some more legs on it to stop it flexing. 6’ is quite a long bench with only legs at the corners

    Dont Dhink it'd survive mate, , I'm 118kg. I shouldn't be, but i am haha

    Fifty odd years of pies n pints :thumbup:

    Re distortion I'm sort of at a loss how to stop it with small box section. Tried clamping down, sequence etc

    If anyone any tips or advice at what sort if size it reduces that would be good

    Think it might be less with 40mm square like Yahmon is planning

    Not much progress, just corner and cross braces for fixing the top to frame

    Bit short on time today so used stick. Saved lugging MIG out.

    Most welds went ok but had my first weld affected by magnet. New ones from Lidl much stronger than old Draper n Aldi ones.

    Bought them few months ago but not used til today, never experienced that before but read about it.

    Arc bounced sideways with a proper loud pop sound and threw my concentration a bit. Moved magnet but still messed it up

    Screenshot_20190910-222222.png

    As mentioned above still need to fit feet to legs and second brace to one pair

    After that its coat of paint and into shed awaiting the time/weather to make the top

    Not going to fit lengthwise braces yet, hoping floor will act as brace once bench screwed down with coach bolts

    Should be enough for its purpose, if not can retrofit them

    For now want it out the weather sooner than later
