12v system can and will be switched off when petrol motor is running. The high pressure filter was an idea based upon past experience with a pump that failed and fired a load of shrapnel through the system on a mini digger I had but it’s optional, one on return side is definitely going to be fitted. One of main reasons for going this route is the ability to use the hydraulics other than when head is back and connections to alternator/12v systems are engaged. I’ve been caught out a couple of times with that and also with big Elm/Ash/Oak etc it gives the the 12v system a hell of a lot to do.

No it’s just me using it and I’ll be labelling it up to try and keep it looking reasonably factory spec. Admittedly valve positioning by people can go wrong. Testing one of the back up systems on this job and all the valves bar one were in the correct position, the one that wasn’t dead headed the system blowing the return line and spewing about 20 gallon of hyd oil onto the deck.
-
Thanks for the input.yeah there is a prv on the existing block, non return valves are an option and would do same job but do occasionally pass a bit. I use kit quite often with a secondary or back up power source and this often entails throwing a couple of valves into position, keeps it nice and simple too.

Hi All Got the engineering guy on nights here to knock up this to show the proposed layout for upgrading the hydraulics on the mill. 12v system is in place, GX and pump are sourced as are return and pressure line filters etc. Just wondering if anyone with any hydraulics knowledge can see anything fundamentally wrong with the layout ??. Cheers
-
No I didn’t think you were, just pointing out its built like a tank and little bit more weight shouldn’t be an issue.
-
Twin axle chassis set up rated for 2000kg each Mill is running at 3t ish, Honda GX motor and new pump plus odds and sods will add 70kg tops. If you’ve ever seen the Trakmet mills close up you’ll know they tend not to worry too much about weight when building them.
-
We have 3 position valves on a lot of the kit offshore to facilitate back up hydraulics on some essential bits of kit being used. Not sure if shuttle is the correct term but we just refer to them as 3 ways 🤷♂️. Fundamentals of the plan are found I think, just hoping a hydraulic guru might have had some input.

Hi All Looking to fit a secondary hydraulic supply to my Trakmet mill. The existing 12v powered system is fine for every day use but when dealing with oversize stuff I feel it’s probably low on power. The system is rated for far more according to Trakmet as it’s the same that’s on the 3 phase static models apart from the motor used to power it. Looking to weld an extra connection onto the existing steel tank to feed a petrol powered hydraulic pump that matches the manufactures flow and pressure specs on the 3 phase models ( Which ive tested and are far quicker and stronger)An extra filter will be fitted on the return side from the control block and looking at 3 way valves to switch over supplies from the 12v system to the petrol hyd pack as and when required. All this will be mounted within the chassis rails at front in amongst the existing hyd systems location. Any advice on likely issues or if I’m totally on the wrong tack would be appreciated. Cheers

Cheers Andy So much for limited markets 🤷♂️

No idea Mark past caring in many ways. There’s people on here that if the cap fits etc have clamoured for restrictions and safety at any cost both financially and liberty wise. Time to pay it seems.

Boris Johnson to defy rebels over tax rise for social care APPLE.NEWS Boris Johnson is in “invincible mode” and will push through a tax rise to fund social care despite... Something along the lines of we will waste billions of tax payers money due to utter utter mismanagement and a ludicrous over reaction to a virus, but expect taxpayers to pay more to cover the debt this has left the country in!!. Safe in the knowledge most will welcome this as progress and a wonderful social gesture.

Yeah I know it’s not cheap. I’m happy with the standard Alaskans Saul, Trakmet will do a 1.2m diameter log so the 880 doesn’t get much use at min which was a factor in why I didn’t go forward with sorting the Panther. To be honest to manufacture the mill to a standard that it had no lash in gears etc or movement anywhere would probs result in it being twice the weight and cost. The guy who’s mill I was using is working for a firm doing decommissioning in the N Sea using ROV deployed diamond wire and abrasive cutting systems so with my background etc we maybe tend to look at the engineering on things with a slightly more critical eye. like I’ve said it’s not really criticism as such it just wasn’t the direction I wanted to go ie fettling something at the time. I’m not adverse to that and currently have a list of mods I want to do on the Trakmet mill to improve things as I see it, some involving pretty extensive fabrication etc.
-
Saul’s words bud “cutting edge” at £600 ish or whatever it was you can justifiably expect most problems to have been ironed out in the R&D process. As an aside if I’d kept it I’d have drilled the long upper tube and used roll pins rather than grub screws as a solution.
-
Cutting edge 👍👍😀
-
No need to explain Saul, I don’t own the Chinese copies my chainsaw mills are genuine and whilst they probably don’t take the beating yours do they have not had an easy life. To sort out one of the issues would of necessitated in my view drilling the top bar and using pins to lock the handles etc rather than relying on grub screws and friction etc. That’s just an example. I use precision engineered eqpt in a sub sea environment on a daily basis so maybe my standards are very high. The technology involved on the Panther mills is far from cutting edge rather just basic engineering. I’m well aware of how to build and fettle a bit of kit and any of the fixes that are done on my mates Panther 881 set up I’ll easy post the outcome. End of the day I was looking forward to the ease of use etc hence buying it in the first place but for me there was basic things that could have been better for the price. That’s my opinion and it was my money my choice etc etc not a criticism of the concept or any individual.

‘Burn in hell!’: Biden faces criticism from families of 13 soldiers killed in Kabul airport attack APPLE.NEWS President became ‘blunt’ with grieving families as they asked him to remember the names and... I’d say Bidens going to realise that joe average American patriots voice carries a lot of clout especially when it belongs to that of a dead soldiers parent.
-
I’d definitely say that’s true, I’ve a pair of Alaskans and whist changing the thickness of cut is a pain they are pretty simple well put together bits of kit. I bought a brand new panther 60 kit and had is sitting in the shed waiting to be set up with the 880, but after watching a mate build and use his I pretty much made my mind up to selll it there and then and stick with the simple proven design. He has had issues with the grub screws on the height adjustment grips coming loose so not gripping the bar and the cogs going out of synch along with a number of other things He is a good machinist and fabrication type so will no doubt stick with it and probs sort out the issues himself but for me it seemed like a fair bit of work to get it where I’d want it to be.

She do it for you then, the rest of us as you put it !!! count me out of that group please, close contact pinging self isolating bullshit, total utter bollocks. Shes no choice seeing as she’s dogged the shit out of everyone about this bloody virus for 18 months. Nothing more than playing a stupid game.

The SNP/Green alliance will no doubt have a catastrophic effect on Scottish jobs and communities, mind you snp are happy to drag everyone down rather than up. Far easier to drip feed the peasants off the state teet that way.

Biden slams China as new report on Covid-19 origins is released APPLE.NEWS President Joe Biden criticised the People’s Republic of China for its lack of transparency after the... Pretty sure Trump was ridiculed by the Dems for this view 🤷♂️. Maybe the orange man wasn’t so wrong about a lot of stuff as the woke brigade would have everyone believe.

Biden rests head on his hands during tense exchange with Fox reporter after Kabul statement APPLE.NEWS Exchange occurred after president called Peter Doocy ‘most interesting’ man in media Worth watching For all his faults at least Trump could hold his own in a press conference. Americans must be looking at this and wondering what the hell they voted for. During this whole mess in Afghanistan he thinks it’s a good idea to throw in a sarcastic one liner to kick off a question !!!

Had it a while now Andy, it was a joe special that and the chain morticer plus a few other bits if I remember correctly for an XJR 1300 cafe racer unfinished project
-
I’ve got one Andy if you want to try it bud before committing its not the lightest thing to handle but does a cracking job. That’s lad doing his mantle piece. You are right though it’s not a cheap bit of kit 🤮
-
Looks like a cracking bit of kit Andy. That’s not great pdi quality control etc to say least. Logs look lovely stacked together bud, I’m sure some strategically placed long timber screws and the weight of the whole cabin walls and roof would go a long way to helping with excessive movement. 👍
