626 Riser Block. I'm not in a position to make one of these at the moment but I like to plan ahead! I've seen a few other folks have made risers for their mills but I still have some questions and would appreciate your comments and suggestions guys! First off I guess is which material to use. I've seen these made in both Steel and Aluminium Alloy. AA would be easier for me to machine as I only have a small Lathe but is it suitable and what's the difference in cost - cheaper is better in this instance! I only have an 8 X 14 Lathe, is this big enough to do the job? I think I've seen one being made on an even smaller ML7. Is six inch diameter (152.4mm) stock big enough, quoted dimensions for some folks risers is 155mm diameter? I know folks have gone up to a six inch riser for their mills but I've done a fair bit of work on my machine and only plan to make a 3-4 inch version. It will be big enough for my needs and I'll still be able to reach the pulleys and belts for speed changes! I think there must be some variation in these machines so I won't be blindly following anyone else's dimensions without carefully measuring my Warco VMC first. Have I missed anything? Thanks in advance. |

I'm part way thru doing two for two different people, both in steel as I have it and both nominally 4" There is an article in the current issues of MEW on doing one but he's done his out of three parts all bolted together so he can use the original short holding bolts. Seems far to much work to me so I'm doing a one piece with a set of new long bolts. Unfortunately paid work keeps getting in the way so these are still a while off and will be for some time as June I'm away for most of the month. What I have found out so far is every one that has been measured is different and I don't mean a few thou. The two I'm doing, same machine but from different stables differ by 12mm !! |

I'm not surprised by the difference in measurements John, hence my earlier comment! Can you remember how much the steel is for something like this? Do you know the issue number for the MEW article? I'm worried my Lathe is a bit too small for this project to be honest ... Thanks for the reply and sorry for so many questions! Update: found the issues, MEW 215 & 216. |

Don't know the price of the steel as I had an eight foot long left over of 6" from a few years ago when steel as a damn sight cheaper that it is now. Bit heavy thought :bugeye: Don't think your lathe will be big enough, Mine is 14 x 40 and it's not gripping on much with the jaws right out. |

Sure I've seen a picture of someone turning one on a Myford ML 7 somewhere, I wonder how they were holding it? |
