Hi guys,
?Thankyou all for the great response to the picture of my hydraulic cylinder,
Bill B,?
? Thanks for the pressure gauge idea, thanks also for the pressure setting, a great starting point & the link to the info, plenty to digest there after a quick skim!?
Rob M,
? I did find the Sawcyl site, it was tempting to buy it, but exchange rates & freight to Downunder had my wallet twitching!

?The article has a bill of material, there are no part numbers as such. If you watch Halligans video he goes into the material sizes etc, just doesn¡¯t specify all the hole layouts etc, although I¡¯m pretty sure you could work it out.
The end blocks are 2¡± x 2¡± x 1-1/2¡±, I made one of mine longer as the needle valve has 1/4 BSP thread not 1/8¡±. The cylinder is 1-1/2¡± tube, I choose ali, the piston rod is 1/2¡± silver steel, because I had some. The piston is 1¡± long ali rod turned to be a couple of thou less than the tube ID. The whole unit uses 4 tension rods using 10-24 nuts to hold all together. I used short lengths of 5mm threaded rod in 8mm ali rod with 60mm button head cap screws to hold mine together. The blanking plugs elbow are 1/8¡± NPT, as above the needle valve is 1/4¡± BSP.....mine is a pneumatic one, 8mm tube fitting, ?you have to make sure that it controls the flow in the right direction! The on off valve is one I ¡° found¡± in the bin at the last place I worked. I then had to get an 8mm to 1/4 adapter as the valve & elbow are 1/4¡± tube. Various nuts bolts etc. Once again Halligan covers these & also the o-rings that he used . Hope that is of some help.
Bart I,
?A lot longer than it should! I went off to get the ali material before going on holiday in February, as usual forgot some bits so figured after getting back from holiday I¡¯d pick up the missing bits, I was straight back into normal work followed by 2 weeks solid, then Covid hit! Once we got out of lockdown & I hoped I had figured out how to cut internal o-ring grooves...oh & making the cutter to do so, it didn¡¯t take too long. It was a fun project. I guess you could build it in a weekend
Dave,
?The material cost wasn¡¯t great, I brought enough 2x2 to make 3.....just incase, the tube & tension rod material plus some spare for the may come in handy pile, the same for the piston material. I had the threaded rod & in my case 12 mm silver steel. The rod end, 12mm female, was less than $20NZ, if I was doing it again I would use a 10 mm male one as the piston rod was threaded 12mm which would tear the o-ring apart threading the block over it. Where I got the o-rings from has a minimum charge....I have since found a cheeper supplier! ?Sorry I didn¡¯t keep a list ?of how much I spent, but would think if I didn¡¯t buy extra material that all up around $50 to $60 NZ. The silver steel (here this is sold in 1 meter lengths, I used just over 1/2 of a length) & rod end would be the bulk of that.
Hope that¡¯s helpful guys
Cheers Kerrin
