That's a Bourgault point which is 19mm wide

Similar experience here, been running Metcalfe points and tubes on our Virkar for 3 seasons now and when its sticky I get a lot of blocks from clay pushing up the tube. Blockage sensors have been essential! Otherwise happy with them though.

one thing on our sabre mounts is keeping them vertical, we have tried both the triangle and round blocks and they all sweep back, would the 19mm be impossible to keep at a vertical?

I have read this on a number of occasions and also read it on here before possibly from yourself. Definitely 19mm will take more pulling than 12mm so will be harder to hold at the correct angle.
As some of you are aware we store there equipment and assist / hinder Agriweld with there development and to be fair haven’t seen this issue with there disc pods even with 2 discs per pod. I don’t know but I wonder if Agriweld have slight more tension in the rubbers by the outer clamp being slightly smaller or wider meaning more rubber to twist or the leverage on the clamp is less due to the position of the arm. but I am going on an investigation mission to check this out and how big the tube outlet is tomorrow.

When we build ours it had triangles in as thats what we got from weaving , then someone said rounds were better so i changed them all for those and to be honest i cannot tell a difference

Been swinging on disc arms this evening to get my arm calibrated ready before tomorrow’s investigation! Will let you know what I learn or notWhen we build ours it had triangles in as thats what we got from weaving , then someone said rounds were better so i changed them all for those and to be honest i cannot tell a difference

So Been to investigate and this is a 2023 machine I was looking at and on round rubbers and to be fair the legs were as stiff as the disc arms on the carrier parked next to it in the shed and similar to the disc arms on the agriweld gear in my shed
Has anyone the metcalfs with the 100mm wings on? Would they flap backwards if the wee skinny ones have trouble? Maybe need a leg in front like a claydon?

I wonder how the tines compare to discs on rubber blocks for peak rotation on the frame. Only a guess, but when encountering stones, a disc will push the frame up more as it rides over it, where as a single tine would have to trip back further, causing much more compression of the rubbers. Would be interesting to see the results if you ran several implements with sensors logging the twist in those rubber springs.

Slowly getting there with the frame design and how to mount the discs or tines on the front etc. Been thinking about the coulter design got some ideas coming together based around the bourgault 19mm point that they're offering as a retrofit onto the weaving sabre tine. Then comes the clever bit :-
- How much to squash the tube thinking 25mm maybe slightly less.
- Side plate design to hold the soil out the slot until the seed drops out the tube as well protect the seed tube
- Some form of deflector on the bottom to stop soil going up the tube (Yes I know I am paranoid about this)
- The seed tube and deflectors want to be height adjustable relative to the point this is so we can cultivate deeper than sowing depth if we need to
- The seed tube wants to be easily removable to clear any blockages (Yes I know I am paranoid)
- 2 pipes for grain and fert ideally adjustable independently of each other
Had a couple of discussions with my gurus / expert advisors about this over the week end and the ideas coming together. One said jokingly 'why aren't you just buying a triton as we all know they are the definitive tine drill and no one's allowed to copy it!' my response was unrepeatable looking at the quality of the design and build and then said I gave him permission to shoot me if I produced something that looked so aweful. If we could buy the coulters as they are very clever would investigate more but sadly they are not interested but the social hand grenade triton marketing department appears to have gone quiet in what should be their year.
good point ! if ever there was a year Triton should be shouting from rooftops then this is it

After further investigation of all options at Midlands Machinery Show and looking at relative costings etc we've bitten the bullet and ordered the Bourgault VOS double entry adaptors with 19mm points for cereals and 3.5' winged points for the rape on every 3rd coulter. Hopefully these won't block up when conditions get sticky, knowing my paranoia about blocked coulters. We will then make the top rubber blocks mounts which will wrap round the 80 x 80 box section which then bolt onto the double entry adaptors. So we have the coulters and mounts covered.
The frame is slowly coming along been a fair bit of discussion as to whether we need lateral float in the 2 2.4m wings or it wants to be locked rigid across the full 4.8m. we'll see what it looks like when drawn up and make that decision then. but frame coming along slowly and some of the bought in parts are starting to arrive, its all starting to get real.

Looking forward to seeing the progress
Interesting, this is a drill thats always interested me, but a front tank rig doesn't suit our back end activities very well unfortunately
that VOS 19mm is what we use and even in 2019 mud we never blocked one
great choice
Don't make too much adjustable. ime with various Triggers brush drills here, what happens is once set some adjsters are never touched again, and some seem to come slack for fun.
If its wet enough to block badly enough to need to remove the seed tubes to clear, then its too wet to be drilling, or you need more clearance in the frame.
A good base for the design is to minimise the need to get out of the cab!

Genuinely they aren’t an issue you leave the rigid pipes on all autumn, have hydraulic pipes and cables all pre fitted to the tractor with quick couplers, have suitable stands or tactically positioned pallets. Then and this is the clever bit how you position them in the shed to go on and off in one swift movement. We back in to the shed drop the back off against the back wall folded up. Then pull forward drop the front off just to the side of the shed door against the front wall then back up touch them forward and away you go. Then to put it on reverse in back on then front and off you go again.
iirc your drill stays on the tractor 365days a year doesn't it? Ours can be on and off 4 times in a week sometimes! And we haven't the shed space to do that either unfortunately.

It’s been off a couple of times this last year for one reason and another and genuinely it isn’t an issue if you leave the transfer pipes in place but as you say rightly you need abit of shed space or there’s slot of shunting
We have a Horstine airstream for fert on the front of the taty planter tractor but it goes on at the start of the season and does nothing else for three weeks. Back end drilling the drill can be on and off umpteen times from August til February then onto spring crops til well into April, not always on the same tractor.
I'm not a fan of the variable weight over the front wheels or giant obstacle blocking vision all the time either tbh, but that's mostly down to wet land, tight villages and personal preference really
