hmm, I'm late again
Please let me know if/when there will be another batch.

Enjoy you new parts ;-)

No you're bang on time, I ordered extras as I intend to keep all my parts available for some time yet

Another RS Ormerod Mk1 meets the world

Retired now but I used to make....
CNC Machined Mk1 aluminium bed support plates for the Ormerod
CNC machined X-plates and ribs for Mk1 & Mk2 Ormerods
CNC machined bed support arms for the Mk2 Ormerod.
Dual Hot-End heatsink blocks.

My 2p worth - countersunk to be avoided unless necessary - the self-centreing action just adds another potential inaccuracy problem. Not saying it will cause an issue, but no point designing one in if it's easily avoided.

Do the screws limit the available positions for the extruder, or the steel bearing tape? (Not got my machine in front of me).

Just checked and I think they might interfere with the motor for the extruder/s.

My solution would be to remove the three notches in the top edge and just have the extruder hanging anywhere between the screws. I just checked and it seems quite happy just clipped on to the top of the plate.

If this is a good idea, please let me know and I will email the laser cutter that a new DXF is on it's way and not to start on the file they have.

I've just tried hanging the extruder on the top, and I find it most unsatisfactory. It doesn't hang at a consistent angle. The extruder is heavily weighted towards one side, and the notch with the lip is needed to hold the extruder level. So I suggest countersunk screws.

Dear Davek0974
Just to clearify; You may take that as a request on my part ;-)
Thank you !

Fair enough, I'll leave it as-is and decide on screws after trialling my own one next week.

Hi

If you have one more I like one also.

Well 5mm plate isn't thick enough for much of a counterbore, and it really isn't much of an issue - so countersunk is fine.

If it does cause any kind of a distortion problem, then simply put it together with cap heads and washers, just long enough for the adhesive to go off - then remove the offending screws before fitting to the Ormerod

Plenty of surface area in the mating surface, so no super special adhesives required ...

I did get a quote from Henkel about gluing and there are several easy to use products in theirs or the Loctite range.

Definitely no room for counterbores, will check when the parts come in.

I did some checking with a scale print of the DXF file and the screw locations do NOT interfere with the extruder locations, should be an easy slot-in replacement and will be supplied with cap-head screws.

Should be with me Friday.

STATUS UPDATE....


I have to issue an apology, the laser cutters rang me early this morning to inform me of a machine problem over the weekend, my parts will now not be with me until early Wednesday morning.

I will be shipping them during Wednesday so there is a two day delay from my earlier dispatch date.

I can only apologise to you all and will hope to get them all out during Wednesday.

They look good, Dave. To look really sexy, they could be polished and anodised - black or electric blue anodising would look superb!

Yes that would look sweet but the price would be silly

They need some fettling with a file or carbide paper but they are not bad, only way to get better would be water jet but I just can't get the prices down into real-world figures.

I was not implying that you should supply them that way, but that people who would like a good-looking Ormerod could do the polishing and anodising after receiving them. Long ago I experimented with DIY aluminium finishing using fabric dye after anodising to colour the metal, and did not get bad results (though it's quite a bit of effort, and commercial anodising/dying is not that expensive).

Giving aluminium a brush effect is quick & easy using a wire brush wheel on a drill, and that also looks pretty good.

Of course, it's a good idea too, blue would go nicely i think.

URGENT - PLEASE READ....


A problem has been identified with the quality of one part of the X-rib kit. The thin reinforcing rib in some cases has developed a bow or bend in it, this is caused by internal stresses in the aluminium being released when the part was cut.

If you notice that the rib does not touch the large plate evenly along its length then do NOT use it as it will bend the main X-plate and give print alignment issues.

I am contacting the cutters today to try and organise a replacement part urgently, failing that then I will arrange another method of remedying this serious issue at no cost of course.

Please note that not all parts are affected, it seems only related to the earlier buyers and as soon as it was spotted, has been fixed on all later orders.

I can only apologise for this issue and ask that you bear with me while it is sorted out to your satisfaction.

I will update here as soon as I have more information.

Dave when I did mine I milled that surface to get it 100% straight, I just added 1 mm extra mtrl that I removed afterwards.

Update....


I have replacement parts coming and hope to get this all straightened out next week (pun not intended ) new ribs will be sent to those early orderers that have bowed items, free of charge of course.

Once again, my apologies.

Mine has a 2mm bow over the length of the thin rib.

Frankly the cut and finish of the whole thing is pretty poor, to say the least.

I forwarded images of these parts to another cutter and they confirmed that without using an argon process gas, these are fairly normal cut examples for laser and aluminium.

The trouble with using argon is that it pushes the cost up dramatically.

I probably will not be making more of these unless I can get better, all bowed ribs will be replaced at my expense, hopefully this week.

Hi Davek0974,
I need a great price (like what you've done) with a bit of work to do.....
But you can also show the right price for better quality ....

Thanks

I think I see what you mean Dario, but unfortunately they must be ordered in batches, minimum qty is 25 sets and paid for in advance at order time.
It would not be possible to do both ways as there is no way to guarantee selling them.

Appreciate your efforts Davek0974

They will clean up into nice looking parts with a bit of attention in the shed, and more importantly, they will do the job - improving the ormerod
