  1. Thats very clever, I'd have never thought of that. Will do! ...... ... what I wouldnt give to be one of your "shop apes" for a few weeks Thomas! I'd learn more in a week than I will in a lifetime of hobby blacksmithing alone.
  2. In my little shop that will be very handy too, as I dont have the space for multiple vices with different throws.
  3. I assumed that would be the answer Thomas but I thought I'd check incase there was some hidden nugget of wisdom about vice jaws Thanks!
  4. Indeed, thanks chaps. Sorting out the fit on those jaws was my next task- it will be easier to do one I have a suitable stand finished.
  5. The jaws are now in position. I intend to dress them with a grinder at some point, including radiusing the edges facing the vice body which may help them sit better. As you can see the alignment of the jaws isn't great. Does anyone have any guidelines as to what the alignment should ideally look like for a closed leg vice? Obviously due to the swinging mechanism they are only going to be parallel at a certain distance apart. I started making a vice stand for this. I still have a ways to go..... Unfortunately, I also made the mistake of leaning the vice up against a cabinet while I drilled out the holes for the stand. I watched in slow motion as the 30kg vice began to topple sideways and crashed into my 3D printer.... I had tools in my hand, and there was no way I would catch it in time. (A stupid mistake. It was a temporary storage location under a bench. Accident waiting to happen. Fortunately the 3D printer wasnt currently in working order anyway, but its certainly not going to be working any time soon now!) *sigh*. Two steps forward, one back.
  6. Absolutely, this ^ Thanks again everyone.
  7. Just to say this is a great video, and very helpful (as are all your videos!) thanks Jennifer! I wish I could make forge welding look easy like you do (actually...... I wish I could forge weld at all, easy or otherwise!)
  8. Absolutely Thomas- I'm good friends with these guys, and the favours go both ways- I often help them out with CAD designs, 3D printing, etc..... but- it would be easy have them solve every problem I ever come across, but the last thing I want to do is tick these guys off..... because when I need their help (like today!) I really NEED it! Hence, I try and only trouble them when I have no other options. The workshop guys will be feasting on cakes and biscuits tomorrow I assure you!
  9. Well, this escalated.... in a good way! Took the vice into the workshop at lunchtime intending to use the pillar drill. One of the chaps had a look and reckoned the hole was too mangled to stop it wandering. He offered to do it for me on the mill! This turned out to be a lifesaver as there was something VERY hard stuck in the bottom of that hole. Even the milling machine with a carbide drill was NOT sounding very happy. Furthermore the hole hardly matched up to the measured holes in the jaws so wouldn't have fitted even if I'd been successful. In the end, my mate succeeded in drilling the hole out in the correct position, and even tapped it for me. Next step, get it home, get the other set of jaws on, and reassemble, then sort out a vice stand. Very happy! Thanks again for all your help and advice. I'd have probably done something silly and ended up in a far worse position.
  10. New removeable jaws made by the workshop. I can dress them up with a grinder and then heat treat as appropriate. As for the "mangled" hole.... I have that half of the vice in the car boot with me. I'll have a go at lunchtime at drilling out the stuck bolt! At least now I can use the jaws as a guide for where the original hole was.
  11. Hi all, Thanks again for all the advice. Still working on this. Tonight I succesfully finished drilling and tapping the 3 good holes. I couldnt move onto the mangled hole as I want to use the jaws as a guide and I left them with the workshop guys. I did try removing it with the "reverse tap extracto thingy" but couldnt get it to bite. I will try once more once I've drilled a small hole knowing the centre point, but I'm doubtful. Thomas et al: are you saying I'm likely to not be able to drill out the bolt with a hand drill? (I have no experience doing so) Maybe I need to take it to the workshop pillar drill. Marc: I hear your concerns re/ M8..... at this stage I dont want to go further to try and move to M10/12, but I understand I'm taking a risk. At my current smithing skill level I'm not likely to be doing very heavy work on it for a while anyway.
  12. Further update: The workshop guys have given up. Whatever material those jaws were made from, its HARD! They tried annealing with a torch and it made no difference- must be air hardening steel. I can possibly anneal them at home in vermiculite, but the guys are going to make me some new jaws from steel gauge plate for now. I owe them some cakes for their trouble! Tonight I'll have a go at finishing drilling and tapping the holes....
  13. If it is, I have some bolt removal bits (basically just like a tap in opposition direction). If I drill a small hole I might be able to use that to extract the old bolt. Depends how badly rusted/seized it is.
  14. Live update: The workshop are fixing the countersink in the removeable jaws for me.... .... I got an email 20mins later to say the countersinking bits couldnt touch the steel as it was so hard! I should have thought to check the hardness and annealed them before I took them in..! I asked the workshop to have a go at annealing them with an oxy torch- I can always reharden them at home.
  15. Hi everyone, Thanks for the tips and advice again! SLAG- I've been using a tapping oil so far, for both drilling and tapping, just because I had it lying around. I was also going to try 3-in-1. I guess I high sulfur oil would be better? What does the sulfur do? Marc- a helicoil is an option but I wanted to try and avoid it if possible. If I can get all the holes to M8 threads, I'll still have plenty of "meat" around the holes. I'm worried about that bad hole though and after your comments I actually wonder if its part of a bolt stuck in there, but its hard to tell. Maybe using successively larger bits as you say is that way to go? IDF&C- great idea- will do exactly that when I come to drill the bad hole. Anachronist- thanks! Yes it was a bit interesting without a pillar drill. As for the mating of the new screws... I work in an engineering company with an in-house workshop. Unfortunately modern Health and Safety rules prevent me from using most of the equipment in there, but occasionally the machinists will do me a favour. I've brought the vice jaws in with me today and will get them to increase the countersink size to suit an M8 screw flush. My backup plan will be to lug the vice into the workshop and drill out any stubborn holes on the pillar drill, but I'm not sure how pleased my boss will be if he sees me!
