  1. I was thinking it's good value for a ULEZ compliant run around
  2. This unfortunately stalled, most likely because of some other project getting in the way. I may take another look ar it, see what has changed in the world of IDA Pro in the last 8 years (currently it's at version 8.3)
  3. I don't think a weld on a spring would last long tbh. This one on eBay for a Record (probably the one you have already found) looks like it would work. https://www.ebay.co.uk/itm/174838116657 It has the following dimensions so you should be able to get an idea of the chances of it fitting before purchasing. (The spring ends as far as I can see look right too) Spring measures approx: Overall length: 83.5 mm External Spring diameter: 19 mm Internal Spring diameter: 14.2 mm Wire diameter: 2.2 mm
  4. How broken? If it's just the end it is usually possible to heat the end of the spring till red and fashion a new end to the spring if you get what I mean. There's a lot more vice nerds over on https://www.mig-welding.co.uk/forum/threads/show-us-your-bench-vice-s.52872/page-434 they might have ideas as to where a replacement can be found.
  5. Have seen a few builds online where they have used the bumpers as air tanks, not seen any failures, doesn't mean there haven't been though.
  6. Excellent! Would swear you went out and bought one if we hadn't seen you make it That's proper lovely to see, you were right at the start, casting your own was the right way. No, the idea is that you are supposed to spend your time doing things you enjoy!
  7. Shrinkage for aluminium seems to be quoted at 6%-8%, does that mean the diameter of your casting shrank by about 3/4" ? I'm sure I must have that wrong, but it would explain why the inner ring was pretty stuck. Proper impressed with your casting ...... and your crucible!
  8. Are you planning on pouring the aluminium directly against the steel? I've not cast aluminium since I was at school but when it cools surely it will shrink against the inner ring, whilst I don't doubt that you can cut the ring out is there a chance that the shrinkage against an 'immovable' object could crack the casting? I'm probably talking out of my backside, but perhaps the ring would be better with some kind of joint that allowed it to slip? Also is there any chance that the steel will cause the aluminium to cool too quickly and ruin your pour? Just idle thoughts which I imagine you've already thought about.
