![]() I do have a R8 bridgeport 3" boring head for 5/8"shank i could use and make a holder.but thats another possiabilty of chatter,I realy dont like chatter. I do like the boring head one for $64 on flebay, execpt for the needing to change size for cutting the entire serface but that type would be a lot easyer then the ones I have now and probably work better size change is almost nothing with those as it stays on the same plane,mine dont the triangle incerts slide so that means up&down and try to get them right then reset the depth.pain in the ass. Ive got the berg style's and one like the rockey one, and some heavy semiround balanced cutters all stamped for thier cylinder sizes and there adjustable too and use the 532 tng incerts.( I think thats the number. 100 radius so as not to create a stresspoint in the corner under #3&2 the three diameters are for the cylinder, then a little smaller for the smaller part of the cylinder, then below that clearance for the piston, and a. The fancy cutter setup has three diameters and a nice radius at the end. The cylinder sizes are semi-standardized.and it's up to your descression how much clearance to give them.005 at the case and. That boring head can be set bigger and do it all at once.SHOULD be able to anyway. and that may be the way to go for the best finish.įor the case you can just use a small flycutter set at 2" or so and drive it around.if the ways are still tight. ![]() There is an expanding flycutter head to do this that is NICE but it is quite an investment.Ĭan also flycut heads in two steps, one at piston size and last at cylinder size, stop just shy. If your machine is very STURDY then you can flycut heads all in one cut, and seems like all the shops have a cutter with HSS blade to do it like this, BUT, if you get too much chatter then it may be better to do a little at a time. There are several ways to surface the case and flycut heads, and all ways can work if done right. Of course it would be two operations on each hole.so slow, but doable. That adjustable boring head appears very STOUT and could be used for all of it, except flycutting heads. Where would you find the information on dimensions for the various case and cylinder openings? Can both those types of cutters be used for simple case decking? Yeah, maybe im a little aggressive also if I use it again ill really get that sucker sharp. I also hone my HHS cutter after each flycut to keep the cutting edge clean. ![]() New heads seem to cut much better then old hard used heads. I have had really good luck on flycuts with a splash of Aluma-cut, and letting the spindle coast to a stop once the final depth it reached. I have a few different styles and also what you have pictured but I have not had to much success with them, always seem to chatter. I guess it just depends if you have one case to do, or you will be doing a bunch more. With the right feed and spindle speed, I get some really nice cuts with mine, and no chatter on a wide deck cut.Īn adjustable boring head will come in handy for other non-vw projects also. I can make one rough cut, a finish cut, and then deck the case in just a couple minutes. I made a similar one, and I have about 6 different tool holders each set to a different diameter. Once set, you wont have to adjust this style with every different diameter. I agree the style above is good, and real rigid, but If you are going to be doing different sized cases frequently this style is pretty handy and really quick. something like this even if its a import will be more rigid.

I think I might be better off buying a regular flycutter Any recommendations on brand and size? I looked at the berg mill set. I am going to buy a flycutter for opening cases, opening heads decking cases etc. Posted: Mon 7:14 am Post subject: flycutter Quick sort: Show newest posts on top | Show oldest posts on top
