I don't have any experience with them, but I don't see why it could not be used with a drill press. The design of it looks like it was made so you would not need a drill press though.

I spent some time last night and today designing, and building the tool that hopefully I will use to open up the cylinder base area on the cases. So far I have this done:   This is the reason I am looking for a trashed 54mm cylinder in another thread. The outer pipe is 54mm and will be inserted into a modified 54mm cylinder. The smallest pipe will hold my flex shaft tool. The small pipe is welded to the side of the middle pipe, which then can be rotated to adjust the cutter. The entire assembly will be rotated in the cylinder while the flex shaft tool is running to cut the cylinder base area out. I may be at a standstill until I get my hands on a 54mm cylinder to sacrifice. One other solution may be to ditch the cylinder, and use the cylinder studs with sleeves/spacers on them to hold my assembly centered in the bore. Time will tell if this idea will work or fail. |

I like the ingenuity you have making tools. Good stuff!

Thinking about using it like this. I just have to get the guides the right size so the tool is centered correctly.  |

Captain not so obvious has struck again! I often overlook the easy stuff, it is a habit of mine! As you can see from the picture, unless I can find a 1/8 shank cutter with considerably more diameter, this tool will not work. I was looking for a larger one a while back, but could not find any. I designed this tool around my small flex shaft tool, when I should have designed it to use a long shaft 1/4 die grinder or something that uses a 1/4 burr. There are PLENTY of 1/4 burrs that are large enough to work, I think? Lol  |

I ordered a cutter, and a mandril from feebay that I hope will bail me out of this mess, I hope to have them by the end of the week.
In the meantime I have been working on cutting up the donor 54mm cylinder to be used as a guide for the tool I am building. (Thanks Brent!) The cylinder has to be honed out a little in order for the cutter assembly to be able to slide in. I priced cylinder hones today, about $25 is the cheapest I could find. I may try to borrow one locally, if I can find someone I know that has one.

That there is some slick thinking.

Sorry, I figured that would be alright because it's larger than it should be at the bottom of the cylinder. You can get cheap brake cylinder hones at auto parts stores for maybe $10-15. They're the 3 stone kind, so no good if you want a hone around for your good cylinders. If you were chopping the cylinder up to get just a portion of it where there are no ports as a guide it could be used.

If you were chopping the cylinder up to get just a portion of it where there are no ports as a guide it could be used. I thought it would fit too as the tool is 54mm. I can get it almost started into the bore at the top, but it just wont go. It would go into the skirt kinda tight, but when it got to the cylinder no further. I cut the skirt off and it is tight like the top now. Nothing a cylinder hone wont take care of! I may just get one from NAPA today. They have a large one for $24.99, and the have a pack with a large, medium, and a small one for $29.99 That kind of thing kills me! I wonder how much I would ever need or use a 3 stone hone? I have the ball hone for the 70cc stuff, and they work great. |

Someone posted a link to ball hones recently and I can't find it. I need one for the 54mm cylinder.

You prob won't use the 3 stone hone much unless it's for a 4T. Especially the little ones like the brake cylinder hone. I can tell you from experience that the little stones can grab ports. The cheap little hones can bend when they catch and then they're junk. Maybe the long stone hones would be OK, but by then you're prob paying close to the price of a good ball hone. I was just offering that as the cheapest thing I could think of, but I think in the long run you'd be much happier if you buy a ball hone and have it around. I've always used the 240 grit on my cylinders, but some like 320 grit. There's some info on that in the tech link below. You can find them other places, just links to a spot that carries a lot of them. Technical54mm 240 gritLots of choices |

Looking at the pic,could you use an eccentric sleeve on the cyl studs to adjust the cutter adapter up and down and still use the same cutter??
