Laser Cut Fixture Table

2mm. That's literally tin. It's just coming off a coil.

3mm 8x4 is £100 if you buy a ton

Who wants a ton though.

Laser cutters I guess

Why don't you just draw what you want?

 

[Munkul]

You'd be better off getting a 20mm top laser cut with the hole pattern you want, ream out the holes, and make a base for it...would be better than everything bar a tool steel table.

Why don't you just draw what you want?

Having fusion issues. I had hoped someone would have some plans for the certi-flat style I could buy off them.

Send me a rough sketch and I'll draw something up for you

It would be a tonne of work, to draw a tab and slot table from scratch. Let alone working out the right amount of clearance to leave.

 

[mtt.tr]

No it wouldn't take long at all.

That's based on experience for instance I know I can draw planning drawings and floor plans Inc. elevations I a couple of hours

You’re welcome to send him what I sent you Brad. That will cut down on his work.

I'd just draw the base then use copy array then construction lines and parallel offsets to get the tabs, again after that it's all copy and paste to use the same cut component to make majority of the parts

Though this seems bloody good value for money.

That does seem good value. I'd just like something a tad thicker. 8-10mm I guess I could live with.

David Demoise on Instagram has offered to send me a 2x1m file he has in metric.

I've been thinking and what Clive said probably is best. Two small tables, that can be bolted together. If I could get some boxes made say 1000mm long. They could bolt the two tables together, making up to a 5m table from two 2x1 tables or a table 3M x 2m.

What is wrong with buying a steel table and drilling loads of holes in it with a mag drill?
I only paid £250 for an 8x4 bench with a 22mm top.

I made plans for this, table is 140cm by 90cm, connecting beams are 140 by 20cm. Had it cut out of 5mm plate, fitted perfectly and is a lot stronger than i would've expected for 5mm plate.

If you want the dxf's, pm me your mail.

If you are going to the trouble of drawing it up, why not do it parametrically, so it is scalable to any size? It would not need a heap of variables: length, width, thickness, hole diameter and grid. You can relate tab size to thickness and a little bit of maths will give you number of tabs on each edge.

I am just starting to look at OpenSCAD, and it looks ideal for this. What I do not know right now is if you can send parameters between files, so it will spit out a top, long side and short side with one set of input numbers.

Looking at the photo above, are the stiffeners under it the same as the sides they are parallel to? If not, could they be made so?

I believe it is possible to post dxf files as attachments to posts here, so if anyone wants to share, please post. At worst, you will have to save as an ASCII dxf and change the extension to .txt .

No need, it will autoscale being a DXF you'd only make the linear array and hole size parametric and you sensibly make them some ratio of the overall size.

Sensibly you'd make all the webs basically the same.

You got lucky! Steel benches like that aren’t held in stock at that price!

Did you see my neighbours tables?

You might have to think a little about the tabs. I do not think linear scaling will work well with them: as the thickness changes, the slot size changes but as the width changes, it does not. Similarly, if you double the length, you do not have the same number of tabs, just stretched. You keep the tabs the same size and have more of them.

Hole size will surely be constant whatever the table size as you do not want different clamps for each table size.

If you are to parameterise it, it is less pain to do a full job from the beginning than half and half. As it is a 2D dxf, it could be done as a Python script instead of the STL from OpenSCAD.

Is there anything to consider on sheet size? If a stock sheet is 2.5 x 1.25, can you get a table that size from it? Are the edges acceptably straight and the sheet square from the stockholder? Can you throw the sheet onto the laser table and dial it in to the machine's axes? Most cutting I have seen never keeps any edge of the parent sheet.
