Long shot, but has anyone seen available flat dovetail stock? Basically a rail section with dovetail and a flat base. I have seen curved one that get gued / screwed to rifle, but not ones with a flat base so thought i would ask here. Wanting to see if i can make something to screw to the top of the Crosman 600 which has a flat top. Weaver / picatinny is easily sourced but it has a very 'tactical' aesthetic that im not after.. Pics below show what I am looking for but this was milled from curved stock (i dont have a mill...) And yes, the gun is still not working and I am getting ahead of myself..   ------------- https://www.instagram.com/js_airguns/" rel="nofollow - J S Airguns Air Arms TX200('s) Theoben Sirocco HW77 FWB 300s Webley Patriot One or two others...

| Do you have access to a milling machine? You could mill the rounded base off if you get stuck. |

Thanks Mike, i can see they would be fairly straight forward with the right gear, but a bit outside of my old drillpress's ability! I will see how the project goes and get in touch once i can source the blank Chers, Jono ------------- https://www.instagram.com/js_airguns/" rel="nofollow - J S Airguns Air Arms TX200('s) Theoben Sirocco HW77 FWB 300s Webley Patriot One or two others...

just a thought here,get yourself a two way compound slide drill press vice,these are bassically very simialler to to bassic mill table,costing approx $100/150 or less you can do simple milling jobs quite easily using one on drill press,machinery house in auckland has then as do tool shed,i gave mine to a neighbour just a while back and did many often quite tricky mill jobs using it years ago before i bought the mill ,you would be surprised what you can do with one these vices on a drill press mate once you learn how to use it and set a drill press up for it as a simple milling machine. cheers mike

further to that post,tungstan tipped router cutters work perfectly fine if run at high speed in drill press on alliminium,and come in many useful shapes at quite cheap prices from toolshed or mitre 10 etc,wd40 fine for a lube on alli with these cutters,you dont reaaly need lube with tungstan cutters but lube does help prevently alli binding to the cutter resulting in rough cuts etc. cheers mike

Champion! I have looked at those previously for the paintball project to mill the bolt slot. Would be handy to have, I will look into it again. ------------- https://www.instagram.com/js_airguns/" rel="nofollow - J S Airguns Air Arms TX200('s) Theoben Sirocco HW77 FWB 300s Webley Patriot One or two others...

you will need do few minor mods to your drill press to get best out of these vices,mainly stiffen up table to prevent it moving or vibrating too much,put some sort adjustable lock on the drill press quil etc,this lock is so you can set to depth more precisely and predicably,but other than that the drill press and vice can do surprisingly good work with bit of patience and taking only small depth cuts,obviously not as good as a proper milling machine,but can still do good and precise work if a little slow,it will get many small jobs done better than many would think.and will give you a simple if bassic milling capability. cheers mike

How long is that bar? I faced off the bottom of a picatiny rail in the lathe, and it turned out pretty good. There's always the Belt sander.

good see you getting good use out of that lathe Paul,you can do pretty much any machine job in a lathe,as long as the job is set up correctly,next time you up this way Paul,drop in and will show you how to made some tooling for machine jobs you can do on your lathe that will make it easier to do evan with bassic lathe tools mate. cheers mike

I've got a 4 jaw chuck, and this was my first attempt at facing off the curved bottom of a picatiny rail. You can probably tell it wasn't centred by the circle centre being to the side, but that seems to be an advantage of the 4 jaw, and it's ability to adapt to uneven shapes. But this turned out well, as it was to be used to mount a bipod.

do you have self centering 3 jaw chuck?these better for general use,maybe can get you one if you havnt got one mate,holding small items like scope rails in chuck,they need be packed from behind to keep them aligned correctly,proberly better done on face plate mate as item can be fixed directly to face plate as will then be machined parallel, on both faces,i dont do much mill work on lathe these days but have made up a clamp for the height adjustable tool holders for the quick change tool post for jobs like scope rails and use fly cutter in chuck to do the machining,any run off when maching rails will affect the amount of adjustment available in the scope,dosnt take much run off to run out of scope adjustment.you can get fully adjustable milling vice setups for tool posts that make milling lot easier on a lathe,these are not that expensive but worthwhile if you only have a lathe mate as they make milling lot easier and the lathe more versitile in what type milling you can do on a lathe.let me know if you want a self aligning 3 jaw chuck and face plate and will see what i can find for you. cheers mike
