  1. Thanks Skipper Billy
  2. Steve - Sorry to miss this post on SGL, but glad to catch it on ABS - funds sent this morning via BT.
  3. Flat Earth one line debunks

    surely you need the GEM to counter the effect of the universe rotating around it's fixed central point (the flat earth)
  4. Twins - Think Danny & Arnie!

    It is a bit of a beast, but not quite the capacity of an EQ8. It should cope with a good 30kg (or a fully loaded C14, should one come along in future) and no doubts it will see me out! Cheers Stu - not quite grab and go portable, but could travel to a star party (I did fit the whole thing and pier in to my old Nissan Micra!). The massive tripod and extension (electronics pedestal) raise this up to a good height and it would make a good candidate for swinging a big Istar refractor
  5. A tale of two mounts - not too much between my old HEQ5 and it's replacement, a Celestron CGE. Unless your compare counterweight shafts. Though the CGE wants a pedestal (for the electronics).. I think I have a solution to fit this on my existing pier, though it came with it's own pier and a massive Celestron tripod. I will need to test and adjust to find the right height in my pulsar dome and order a Losmandy dovetail in from FLO.
  6. Mancave Open and New Toys!

    Things certainly were over engineered to last back in the day. Glad to hear your Dad's had such a good return on investment and hope he's still fit/active and able to offer some advice over your projects.
  7. Mancave Open and New Toys!

    My original intention was to be able to make some mounting hardware and adaptors. I would love to have a proper mill, but having such a limited space will play with what I have for the moment. Making a mount would be a true test of engineering prowess - I will try some worm and gear hobbing, but doubt I will ever achieve the accuracy required for a stepper driven mount. Perhaps something friction or belt driven with a renishaw encoders
  8. Mancave Open and New Toys!

    Not actually heated, but I've stopped the drafts and, when the tumble drier's running in what used to be the other half of the garage it's nice and toasty!
  9. Mancave Open and New Toys!

    Peter, if you look down from the headstock of the Colchester, you might notice a few Boxford bits on the floor. I picked up a saddle, cross slide, apron, tailstock and countershaft a few years back and haven't had the heart to throw them out.
  10. Portass Lathe - Finally at home!

    Chris, for some reason I've only just picked up the update on this thread, but nice to see this up and running. This looks nice, clean and all there and will really look nice once it's painted up. Not sure if I would go down the blue hammerite route though, it's not the best finish - any engine enamel should be hard and oil resistant enough and go straight on to an etching primer - Paragon paints do a range of enamels in lathe colours (Myford, Colchester, Boxford) https://www.paragonpaints.co.uk/Myford-Lathe-Green.html - these have a long wet edge and should give a decent finish with a brush. Prep, degreasing and careful masking are the key! Did you make up the motor and countershaft stand? It's nicely done and I really like the flat belt tensioner clutch arrangement
  11. Mancave Open and New Toys!

    Thanks all - though I must state I've pretensions, but no real claim to be an engineer! Forgot to mention that the Lathe weighs in just a little short of half a tonne - Although I had a hand to collect and get it home, I manhandled it into the garage and final position on my own over two weeks ago, pulling muscles I didn't know I possessed! Seriously hoping that this is my last house and lathe! I will be bequeathing the lathe in my will with the other chattels
  12. Mancave Open and New Toys!

    Thanks Steve - I'm concentrating on going very slowly and not loosing any fingers, but I now know who to ask now when I get stuck
  13. Mancave Open and New Toys!

    It's taken a long time, but the home workshop is finally a reality - some two years and a half years since moving in. Rather bijou at roughly 8'x8' and plenty still to do (shelving, replace the old up and over with side hinged doors and make space for my 'new' pillar drill). But everything works and I am officially open and ready to start playing I'm thinking some basic steam/standing engines as an introduction and something to engage my lad. 'The World Turns on Colchester Lathes' - Those were the days! I wimped out a little and brought a Transwave Static Converter to run the Lathe via the existing wiring harness as this will run both the lathe and suds pumps (suds pump can only run at the same time as the lathe motor). I will probably keep an eye out for a 3 phase 240V motor and digital converter in the future, but not cheap and would have to either replace the suds pump or buy another converter just for this. The pillar drill is easier (being single phase 240V), but still languishing at the office until I find space (and own up - though this was my cheapest purchase at £ 56!). This is a massive and lightly used Naerok (Korean made) PID25P, with a 1.1KW motor and 9 speeds up to 2550. I'm hoping I can gently abuse this for a little aluminum and brass milling, having picked up a basic Axminster compound table in my local classifieds. At least it's sorted out my cloudy night activities for this winter!
  14. Arduino Ascom focuser Mark2

    Look forward to seeing this and probably will have a look at the Nema17's too! Worth saying I struggled with 28byj-48 steppers, which was not quite enough to move the OC2 focuser, FW, Barlow and Cam on my OO newt (via 10-30 MX belt reduction). However, earlier in the thread someone pointed to a 12v version of this motor which has worked brilliantly (even working supporting my DSLR and coma corrector). Though, if you are directly connecting to the focuser shaft a more powerful stepper like the NEMA17's is needed.
  15. Thanks Steve - Just looking at doing this for my own 2.2m pulsar and was originally thinking of using DC motors/wheels. However, I really like the idea of a bonded CNC drive belt as this could serve dual purpose (drive and a rotary encoder) - Any chance you could post a few pics and comments on the belt and how you bonded this.
