From time to time I help a friend out, and fellow madmodder, with tooling for his old leather making machines, I've one or two jobs outstanding so I thought I'd get stuck in and get them done. OK first Job some hole punchers this is the machine they are for You wind a handle and it punches a row of holes for a belt etc, when Ray got the tool there was only one rather beat up punch with it so I made him a new one which seemed to work ok, so now I'm going to make a set that will cover a range of hole sizes First job from 1/2" silver steel make up some blanks plus one spare. Thats it for now domestic duties call, but I'll begoing on to finish these off heat treat them and grind a nice sharp cutting edge. Cheers Stew |

OK I've put the punches to one side for now as the next operation on them I want to do with collets, so rather than take off the chuck just to put it back on again I decided to do a bit more chuck work. This is for a plattern to use on a fly press what you do is sadwich a piece of leather between a laser cut die with a pattern in it a sand filled leather bag and then you give the leather bag a wollop with the plattern that is fixed in the fly press and you get is something like this. Ok first job turn up the 1" dia spiggot and thread the end M12 I cut the thread with a die, part off and her it is with the chunk of steel that it's going to fit in to make the plattern. Thats it for now schools are on their half term at the moments so the boss is commandeering my time :wack: :wack: :wack:. And I've got to try and find some sand to help heat treat the punches Have fun Stew |

The last week or so much of my time has been taken up with Family and Domestic duties so progress in the shop has been a bit slow. Finished a bit of a gardening project yesterday:- dug out an overgrown rose bed, put some edging blocks in and planted some bulbs and primulas, I want to leave it until the spring to let the weeds left in the ground to grow through so I get get rid of them easy, then I'll plant something a bit more permanent. As you can see I come from the keep it easy and tidy school of gardening. :D My DRO mill project is on the back burner until this afternoon when I'm going round to Johns for him to do a bit of drilling on his mill, these visits are always educational. So picking up these odd job threads again. One of rays machines puts a seam around the edge of leather belts/straps so I made him some extra rollers so he can do a double or treble seam. This is the machine And these are the additional rollers I made him Just washers realy. Next Job was to do some more on the hole punches Turn the OD and drill the hole. Job held in ER32 collet And this is the set finished turned I made some spare of the larger sizes. Next job was to heat treat the punches this is my set up a Clark propane burner some fire bricks to make a little cave and a good dollop of water, when you've got a few to do don't skimp on the water as it will soon start to get hot and you will lose the quenching effect. These are the harden punches, in the fire brick cave, I put all the punches in the cave and moved each one in turn to the hot spot when up to cherry red it went in the water the next one was put in the hot spot etc etc that way they all had a bit of a pre heat. Next job give them a polish and then onto to tempering. Have fun Stew |
