Hand Cranked Forge Blower Build Here are the pictures of my Hand Cranked Forge Blower Build, made using a Mole Hand Grinder found on the internet (which has a 1 to 10 gear ratio), some old side pannels off a PC, a few small rivets, some protective steel corners that came with a kitchen worktop and some 12mm Aluminium angle iron. Here are the picture's of the grinder on its own. The back piece with the right angled brackets. Starting to rivet together the fan blade using 12mm aluminium angle iron. Cutting the brackets to size and drilling the holes for the rivets. After riveting the first part of the fan case together. I then ran out of rivets but decided to continue using cardboard to check everything would work alright. The rivets I needed arrived and so the rest of the fan surround went on as well as the bolts to hold the front panel on. Here is the fan blades and mounting disk, its not perfectly balanced so does 'wobble' abit but it should be fine for the amount I will be using it. And here is the 'almost' finished blower. I ran a line of bathroom chalk around the joins on the inside of the case to cover any small gaps and the bolts hold the front on tight. I don't own a hole saw large enough to make the 80cm dia hole in the front so lots of small holes with have to do for now. All that remains is to find a piece of tubing to connect the blower to the forge and then try it out. The blower seems to be providing a reasonable amount of airflow although I think it isn't recieving enough airflow from the holes in the front. Ill try to take a video when its working and post a link to this thread. This blower has probably cost me between £40-£50 and around 30-40 hours of time, I'm a pretty slower worker but when your doing something you enjoy the time really doesn't matter. Buying a hand cranked blower in okay condition would have most likely cost £60+ but I wouldn't have learned anywhere near as much as I did by doing it myself. My original inspiration came from this thread here: http://www.iforgeiron.com/topic/22816-home-built-hand-blower/ If anyone has any suggestions or advice, or wants to ask any questions then by all means feel free. Thanks for reading and hopefully there isn't too many pictures, I know how much you guys enjoy them. Tom
