The listing I got the bags from is archived now so can't access it to confirm but from memory the bags are 450mm (18") wide x 610mm (24") deep. But I asked the guy I bought them off when he's getting more and he'll have them in at the end of this week so I can see the sizes then.

You'd have to have a bag to hand really so you could make it to suit that. Defo going to ask the fabby near my work what he thinks cost wise though.

How much do you think you'd do it for Ian if you did?

Here's the £225+VAT & delivery one

And the £145 including VAT & delivery one

The cheaper one looks different! Like it rocks instead of tips

I think you lot are living on another planet if you think you're going to get something bespoke kocked up for £50. Who's going to do the drawings so the thing actually works?

Green one looks a piece of piss to build cheaply and have it tilting

I guess I could. My main job is using AutoCAD.

I agree after what people have said £50 is a bit optimistic, got to take in to account someone's time as well as the materials & make a profit.

Edit- just realised the link to that green one tells you the dimensions of the tray

Make an H frame from some 2" box section. Use a heavier box section for the upright like some 4", at the bottom I would drill two 12.5 mm holes side by side through the frame and into the upright, weld two m12 captive nuts behind the holes in the upright and you bolt those two together.

For the top the tray can either be cut out and bent up then welded or 4 individual parts welded together.

For the tilting you can go a couple if ways, one being a fairly heavy duty hinge or more difficult to explain but I would make a bush using two pieces of tube, one inside the other with a fairly close fit and pack a little grease between. Outer piece welded to the top of the upright and made a bracket to attach the inner piece to the tray. You would need a stop on the back to stop it from going backwards

You could also do similar with wood but using the hinge rather than bush tilting

I'll make you one for £80 if you sort the delivery.


I would rather lose by a mile because i built my own car, than win by an inch because someone else built it for me.

any decent fabricator will sketch something on the back of a napkin in about 5 mins to knock that up

Its not a fucking house, it doesnt need an architect

My exact thoughts, welder/fab at work would do a chalk scribble on the wall

like fuck, it would be a waste of material when you completely fucked it up due to basing it on a sketch

Bollocks. It's not a precise piece of machinery. Far too many new skool wannabe engineers in here

You can't even imagine some of the stuff that gets built in work from a sketch, fuck sake I just wrote how I would build it from the top of my head and I know it would work but that's because we have to come up with solutions without fancy drawings or computer program's. it's a log bagger not some major engineering project

What are the legs, 25mm box?

Need the designs for it really instead of guessing, be a bit late by the time you've made it and had it galvanised to find the bag doesn't fit.

It'd also need delivering. Not sure you'd be much under £200 tbh.


Of course you could Bend the back up,

I some times makes 4sides metal boxes at work from one piece of steel.
Folder/bender at work has fingers and you remove the ones to clear the sides.

My dad has done this stuff for decades, would knock that up without even thinking about it.

Is there a demand for these?

If you want to waste the sheet. It comes 2440mm x 1220mm and is expensive, the trick is to make a few the same and not be left with any sheet left. I'm not really confident you could do that on a napkin.

Which assumes the width of the bend is the same as the fingers.

Not saying its impossible, just thinking you'd not have complete freedom to bend around the width of the bag.

I'd say its a bit cheap for production but as a prototype run I'm looking forward to making a batch.
