fesm_ndt Posted May 3, 2013 Share Posted May 3, 2013 i'm glad you asked that question mike as i was wondering what method you would use to make a piece of steel armoured. my churchill has one or two holes from 84mm law and around some of the holes the steel which is 3 inches thick has delaminated into what looks like thin sheet less than a 1mm thick. is this the face hardening coming away ?thanks for the tips adrian, drilling from the soft side out is the way ahead. simple when someone shows you how to do it. rick Actually curious what Adrian's answer is going to be as on one hand we would always think whack a piece of 3 inch thick plate in, with a huge bevel and I guess a lot of runs. But if you are not going to be getting shot at in the near future you could weld in a bit of 3/8 plate each side and grind it off. I suppose it depends what scrap you got laying around. PS if you do want to whack an exotic hard bit in I can most likely find some 3" thick off cuts. I don't think you will have any real drama welding it as long as you keep it warm as the thick material around it will suck the heat out. Is the delam on the inside or outside as I seen spalling like that? How you plan to remove that, by oxy to burn it off? I am going to a meeting next Tuesday regarding a new armour project, I would say mid level type of armour which is just basically the same concept of face hardened but with a bit of pixie dust inside as they have fancy names for it all now. Hence why I am so curious what's the difference between then and now. The welding on the stuff here has very critical parameters. Quote Link to comment Share on other sites More sharing options...
eddy8men Posted May 3, 2013 Author Share Posted May 3, 2013 hi mike thanks for the welding tips. i don't have any close up pics of the delamination but it's on the entry side of the hole, i'm going to the yard tomorrow so if i remember i'll take a close up pic of it. here's a pic that shows the extent of the damage caused by the shaped charged weapons to the churchill, although the holes are only 20 mm dia there's hundreds of 'em !

eddy8men Posted May 9, 2013 Author Share Posted May 9, 2013 things are moving along quite nicely, although we have hit a few problems the most serious of which was the bearing on the starter collapsing so i'm off to collect another tomorrow. the good news is when we will fit it the engine will be ready to run :cool2: Quote Link to comment Share on other sites More sharing options...
Old Git Posted May 9, 2013 Share Posted May 9, 2013 Shame about the bearing mate but better it went now than later. Great news about the engine though, I do hope Pete can get it recorded, I can't wait to hear it roar. I'm loving those pics Rick, especially that internal shot of the mantlet...In the words of Frank Carson "that's a cracker!" Quote Link to comment Share on other sites More sharing options...
the_shadock Posted May 10, 2013 Share Posted May 10, 2013 great pics. I knew you were missing the gun, but was not sure that you had a mantlet for the turret. P-O Quote Link to comment Share on other sites More sharing options...
eddy8men Posted May 10, 2013 Author Share Posted May 10, 2013 got the new starter and fitted it at 7pm, then went for an engine start with no joy so chucked a bit of fuel down the carb/manifold (it's a wierd set up) and it fired up briefly which was good enough, so tomorrow if we get time we'll see if we can get it running properly :-D as for the main gun that is the last (i hope) stumbling block but i have a few leads i'm chasing up so i'm sure i'll come up with something that looks the part . rick Quote Link to comment Share on other sites More sharing options...

eddy8men Posted May 10, 2013 Author Share Posted May 10, 2013 that's the plan bill, i also wanted to take it to tankfest and YWE but i just don't think it will be ready in time and from past experience i've learned not to commit to shows where it's unrealistic to make it and besides i've enough pressure just getting it ready for W&P Quote Link to comment Share on other sites More sharing options...

ajmac Posted May 11, 2013 Share Posted May 11, 2013 Do you know a friendly local farmer? You will need some ground to get some hours in to knock out the faults (you know what I mean Bob) and get confidence in her before taking it all the way to a show, only to find out its got issues.

Old Git Posted May 11, 2013 Share Posted May 11, 2013 I've got a quick question re the OSP's (outer side plates) on the Cromwell. These are the plates that cover the road springs. I know that they hung on the side in four sections but how did the mate together, if they mated together at all. Was there a 'lip' where the plates met or did they simply butt up together? Can anyone shed any light on this? Anyone got any pics? Quote Link to comment Share on other sites More sharing options...
eddy8men Posted May 12, 2013 Author Share Posted May 12, 2013 from memory they simply butt up. for a better look follow kevin powles thread on my old centaur resto, as kev's taken some pics of the hull with the outerr plates removed.

eddy8men Posted May 12, 2013 Author Share Posted May 12, 2013 (edited) we ran the engine up for the first time yesterday. here's the link to the youtube video (i'm the guy with the grin from ear to ear) [video=youtube;ZV-jzQRYaTo] rick Edited May 13, 2013 by Marmite!!

ashtonpete Posted May 12, 2013 Share Posted May 12, 2013 Just to inform that the spring on the pulley mechanism was temporary and has now been removed. Its been a hard slog to get this far so the excitement of driving it will be as refreshing as that beer John Mills had in Ice Cold in Alex.

I am deeply envious...my little 1/6th scale model seems quite paltry now! Thanks also for the info on the side plates Rick, I shall have a look for Kevin's Centaur pics!
