    Dizzied? lol, my wifes nick name came from an auto correct issue.. changed here family name from Wardle to Waffle... it stuck.. Thanks Peter Thanks Steve, A slightly more appropriate chain has turned up now, will fit it tonight.. just as a back up if anything gives, it'll stop the legs spaying too far.. if im honest I don't trust my DIY after some appallingly bad floating shelves I put up, that also fell down again! that big chain is now holding a friends 6ft driveway gates closed for extra security.

    Mmmmmmmm the spreader chain is maybe a bit over specified.. it'll take 160kg before it gives though.. which is nice

    Where to get optics for a refractor?

    Hi Kari, You could try Astroboot for cheap and chearfull, removed from an achromatic scope lens, usually 60mm or 70mm I know IR Poyser sell doublets.. http://irpoyser.co.uk/lenses/ Ta Fozzie

    Morning All.. Tripod build update and an important warning first off if you decide to work with an "oily" wood like Iroko. WARNING.. I'd been warned that Iroko wood dust was or had the potential to be irritable so I got a dust mask from work and impact glasses for routing and drilling.. Yesterday I spent the morning routing the various element's, dust mask and glasses on as my PPE. Last night I was weezing and looking my voice. Any dust is bad.. this iroko dust is so oily it's like Lilly pollen, it sticks to everything and is so fine the dust mask was bright yellow and clearly when working with it you need to be open air or have better dust extraction.. there was A LOT of dust to contend with.. it's taken me all morning to clear out the garage and hoover it.. So H&S advice.. make sure you wrap up safe and have the correct equipment even for jobs at home.. On to the tripod. So far I've cut out the foot section, routed the chamfer's and radius of the hinge, cut out the 37mm holes and inserted the spike feet. It's by no means perfect and I've found the wood has a habit of splinting annoyingly with will need a bit of sorting.. Only thing to do now is the hinge drill, the tapering of the feet and a bit of decorative routing to the face of the legs.. So far, I'd go a strong 7 out of 10.. learning some new tools and skills here as we go.. Ta Fozzie

    The Iroko is not overly prone to excessive movement once dry, heck it has less than 5% shrinkage from original to kiln dry state, but I take your point about general shrinkage over time providing movement between the lugs. Now I could get some M8 metal spacers at 35mm long, with a rough M10 o/s diameter. If I over sized the hinge drill I could tap this into the centre part of the tripod leg, with washers taking up the remaining slack. That would provide the stability and leave the wood to shrink around the spacer over time. The only issue here is it would be a 10/11mm hole rather than 8mm leaving not much coverage (less than 10mm of wood) surrounding the hinge. My issue with removing the centre part of the wood/tripod connector is that the legs would then only be secured by 10mm thick wood either side, which would leave me concerned about breakage of the wooden legs at this point. I'm leaning towards keeping the tripod legs as I've drawn to avoid cutting to much out and weakening the leg too much at this point. Something to think bout, but i'm leaning towards either this M8 sleeve or just sticking with the original and watching for shrinkage of the hinge over time which could be taken up with nylon washers.. Don't I wish it was... when I started this I wrongly assumed as the EQ5 is a clone, the tripod hubs were identical to one and other.. thanks for the thoughts gents, keep them coming!! Ta Fozzie
  9. Some great photo's here, I just don't know why I don't have any recollection of this..
  10. I remember those, chocolate as thick as a wrecking ball so you had to use the door frame to crack them open. things were proper back then.

    Thanks Peter, those photo's demonstrate very accurately the inverted triangle @Rusted has been discussing. I guess this is the only bit out of my control, shall we say, as I've chosen to use a pre-manufactured hub from an EQ5. Maybe next time I could look at turning a tripod hub out of wood to so I can increase the overall width of the tripod top. I guess part of doing this, especially with the vixen hub, was because I couldn't afford a off the shelf wood tripod, and I wanted to demonstrate what could be done/achieved with "relatively" common components, such as tripod hubs like the EQ3, EQ5 and old GP etc. I've got to say I've enjoyed having something else to do on an evening when the kids and football is done (read while the wife is watch love island), whether the fixed height tripod is as good a result as the last one though will remain to be seen, but from test samples of wood I've done, it should look the part at least!

    Oh I see.. no that's not what I was planning on.. this is more representative.. the entire top of the tripod leg will be solid, clamping the two tabs, using large Teflon washers to close gaps, spreading the load.. acting a bit like the metal spacer you originally noted. ta Fozzie

    Not so much old fashioned, but vastly experienced i suspect! Thank you for the response, to be honest a few bits are totally beyond me, but i'll try and comment back as you took the time to write up your thoughts. That’s correct, the EQ5 tripod hub will be the “donar” hub as you call it. The legs are intended to fit around the lugs as shown, so they will be both “outboard” and “inboard” of the lugs. Teflon Washers will provide packing to prevent any looseness and stresses from snapping the lugs off when tightening the cross bolts. These bolts will be high tensile M8 85mm long. The top of the tripod legs will be 75mm. I’m not in any way shape or form an engineer, and reviewing your blog, your engineering and DIY skills are obvious for all to see. Whilst I understand this comment, that the mount will still experience rotational torque, would that not be a feature of all mounts, or is this a specific warning to my proposal? I’m hoping that having the tripod legs, square to the donor hub and sturdy enough will overcome these forces, the spreader will aid by controlling the legs, adding to the overall resistance, and prevent the legs from any twisting motion, better than say a chain.. As I’m at 75mm wide already, the only way to increase the stability would be to reduce the height (length of legs) so increasing the height/width ratio. Again, I’m no engineer but do we think 1350mm high legs are too much/unstable? Those are great mounts but way over engineered for my skill set and requirements.. The iroko wood has a 25year lifespan, very durable and is extremely resistant to both water and oil based preservatives, I’m hoping it will take a while for any water damage or rot to effect hinge. Providing I can drill accurately enough, I’ve access to a pillar drill that will do the job, then hopefully this will be ok, with out the need to sleeve the hinge with a metal tube. That’s a good way of fixing that I’d not considered before, if the above hinge fails I’ll absolutely look in to that. Again, thank you for the response, hopefully mine hasn't "dumbed" it down too much, but my endeavours are to simply replace the tripod legs that came with a generic EQ5 in to something that ultimately looks better and might offer a bit more stability and vibration dampening. As always.. feed back warmly welcome! Ta Fozzie

    So I'm messing around with the off cuts, after setting the height to 1350mm of the legs.. that's a extra 100mm over the sapele tripod. I'm testing different wood finishes however because I have two pieces of sap wood and one heart wood the final appearance of the legs is going to vary drastically.. the heart wood will be the north leg I think. So the finishes are Teak oil OSMO red ceder uv protection OSMO light oak uv protection Ive also got some clear OSMO uv protection which I'll try later on. Here's the impact.. Untreated cuts Treated cuts, teak oil bottom, oak at the top The heart wood is the darker. It's almost a shame it's not 3 of a kind... Still though, nice wood.. Ta Fozzie Ps it's defo the same wood... look at it and on, you can see where it's been cut..

    Someone Joined Me In A Bit Of Observing.

    I've got an inquisitive hog, the back of the garden is a bit of a through route for him.. the other night I had an owl sat on my neighbours tv Arial for about 10mins.. which is a first..
  17. What about the new vixen 81ed mkii.. 625mm FL, about 3.5kgs and designed for use with full frame DSLR.. expensive though for an 80mm relative to the 80mm ed skywatcher offering..

    What did the postman bring?

    Postman dropped of a berlebach spreader and few items for my wood working.. couple of drills, router and mitre saw..

    The Iroko wood is here and I've got a piece with beautiful grain running through, i suspect this is cut in a different plane to the othe pieces, it'll make a great north leg.. The pieces are 1600mm long, the chap at the timber store cut me some longer pieces so I can test finishes on them before I apply to the main legs once I've worked them.. Few more bits in the post for next week and were good to go! Ta Fozzie

    Delos 12mm Mint Condition

    To be fair I tried to sell on a 10mm Delos for £220 last month and it didn't move so I don't think your a long way off price point..

    First rethink of the tripods.. Looking at the EQ5 hub, after I've taken the metal legs off it's quite different to the vixen GP hub.. so I'll need to rethink how i attach the legs. Two options I can think of.. firstly notch the top of the legs so that they fit between the brackets, or cut grooves and adjust the position of the bolts by a few mm over wise the outer leg bits will snag, it will only leave 10mm cover on the wood.. should be enough though! Will draw something up tomorrow. Ta Fozzie

    I've actually just added a berlebach spreader to this, so it'll end up costing around a wee bit more, but the spreaders are great bit's of kit and really add to the overall stability. So check list of items. Wood - Got berlebach Spreader and fixings- Got M8 85mm long Bolts, wing nuts and washers - Got Thread Insert M10 20mm deep - Need Rubber feet - Need Chain and Fixings - Need Next job is to take the old metal legs of the EQ5 and pack them in the loft. I've also been offered some off cuts of the Iroko so I can test the finish I want to apply. The Iroko is quite an oily wood (apparently although I've read differing opinions) a bit like teak, so oils don't overly take. I want this as natural as possible, and it looks like the best finish might just be a light Oak stain followed by a few coats of UV protector.. but that's for permanent out door furniture, which this wont be.. so we shall see. Will post pictures of the wood when it lands Ta Fozzie

    COMPLETED - Found - Spreader Bar

    Found..... Many Thanks @Alan White..
  24. Hi All, I'm looking for a Berlebach Spreader bar as pictured, for a new tripod build.. long shot I know.. Must be in good condition, don't need the leg clamps as I will make my own. Thanks. Fozzie
