Waterjet cut Aluminium OX Gantry plates

For those that are having trouble obtaining the OX gantry plates, I can offer Commercially waterjet cut Gantry plates to help get your build off the ground. The set includes the 4 Gantry plates and 4 off the frame corner brackets all cut from 6mm Aluminium.

I had a set cut for myself and they turned out pretty nice. Buying single sets of parts is quite expensive , however the service I used offered significantly better prices if ordered in bulk, ie if the full sheet of Aluminium is utilised. The discounted cost is AUD$77 per 8 piece set, the single set cost me AUD$115.

I’m not interested in making huge profits through this venture, I’m asking cost price plus 10% to cover my incidental costs (local freight, packing materials, etc). So the cost would be AUD$85/8pc set plus postage. There is a 22 set min order qty though, if there’s enough interest for them I’ll order a batch.

It would be a 2kg parcel so International shipping from Australia may be a bit expensive, although I may have found an economy air mail service that would ship to the US for approx AUD$35 for example.

For anyone interested in doing a similar initiative in your local area I’ve attached the DXF I used to cut my parts, they are as per Kram242’s design, the only difference is I’ve removed the OX logo to reduce cutting costs and added the 4 triangular corner brackets.

Cheers

Hi Yusef,

I'm in Melbourne, the plates would fit in an Auspost Medium (3kg) Pre-Paid Satchel so postage anywhere in Aus would be $13.40.

People in Melbourne are welcome to collect from me.

 

Hi Franco, that's great. AUD$120 will cover the parts and basic postage, insurance would be $8.5 extra ($150 coverage).

I'm looking at using this postal service, http://www.skippypost.com.au/

 

I thought I read somewhere that there may not be enough adjustment in the eccentrics to

That's correct, Australian price would be $85+$13.40.

 

No problems, I'm not going to ask for any money until there is enough numbers to warrant ordering the parts though.

I need 3-4 sets for friends and colleagues, and between you and maybe Yusef thats 6. I'd like commitments for approx 13-14 sets so I'm not left too far out of pocket and I'd take my chances and offer the leftovers on eBay and the like.

Also, if any changes need to be made to the design, they can be incorporated now. I read a couple of instances in the build discussion where it appears the eccentrics may not have enough adjustment to take out all the freeplay, if this is a concern I can reduce the pitch spacing between the V-wheel mounting holes. Unfortunately I wont have any 20x80 until April to verify this myself.

 

Thanks for offering to do that, perhaps if I find this set of parts is too loose I'll update the DXF and send it to you. I will know within the next week or so if the hole spacing is ok or not, the local v-slot distributor had a small offcut of 20x80 which is probably just long enough to do this verification. My Openbuilds hardware should arrive this week as well, too bad the v-slot probably won't be available here till April.

 

I have trialed the 2080 offcut in the first set of plates I had made and they fit up very well. Less than half the adjustment range in the eccentric was used to snug the rollers onto the rail.

The cut quality is pretty good, the holes are marginally undersized as they come off the Waterjet table so I cleaned them up with 5mm and 9/32 drills and they are fine.

Attached is an image of the eccentric nuts hopefully demonstrating the range of motion used to snug the rollers onto the rails. Therer is also an image showing the parts that are included in a set of parts.

Now that I've confirmed the plates work with actual parts I'll be ordering a batch. Let me know if you'd like a set.

 

I should have these plates sometime next week.

 

It looks like airmail charge to Italy would be $50 + $7.25 insurance ($125 coverage)
There is a tracked option that is available for an additional $10.

Rates can be checked here; please not this is an economy airmail service so may be a little slower than Australia post.

The parcel is ~1.9kg for the calculations

 

Picked up my batch of Gantry plates from the Waterjet cutter today. All looks good, I verified these parts on the 20x80 I have and the eccentrics tighten down without a problem.

They are AUD$85 plus postage for the 8pc set.

 

Hope it works for you, let us know your results on the plasma cutter.

Cheers
Anthony
