    not to bad if the small step is your only problem so far ....something a better tool might fix on the "production model" on a side note if ya dont wanna use a .015 e.m. to cut those peices of stock off ,you could buy a $500,000.00 edm wire machine to those peices off lookin good ,and going strong widgit!

    A little more progress today!

    After removing the vise from the mill, I rotated the turret 30° and extended the ram. Them I mounted my 6x9 angle plate on the end of the table, and dialed it nice and true. Then I bolted a little side plate on to the angle plate, so that I would have a solid 90° corner to work from.

    After all that, I clamped one of the "L" shaped parts in that corner, so that I could drill, tap & ream some holes as accurately as possible. These holes will mate with holes in the x-axis front & rear plates, and the "L" will also have the Double-V track fastened to it. Those holes will go in later.

    Next, I clamped the X-Axis slide block in the corner, so that I could drill, tap, ream, and c-bore several holes.

    All the details on this part have to be done from the end, as the V-Groove bearings and felt wipers will be mounted from the inside! Also, there are six 1/4-20 UNC tapped holes and two .1876 dia. reamed holes to attach the Y-Axis side plates.

    The Felt wipers are held by two #2-56 UNC screws, so I had to drill a hole that's slightly bigger than the body o the tap, so that I could get the little tap through a 1" thick section.

    Also, two M6x1 threads to fasten the two stationary V-Groove bearings. Then a deep 1/2" dia counter-bore with a precision diameter hole at the bottom. This was for the V-Groove bearing with an adjustment cam attached. The counter-bore enabled me to get a 5/16 hex socket and nut on to the little cam shaft.

    Now I have the Double-V groove tracks and bearings finished on the X-Axis slide block. I like the fact that the bearings are adjustable, so that any slop can be eliminated as the machine settles in with use!

    Oh yea, I had to modify a 7/16" open end wrench so that it was thin enough to access the nut under each V-Groove bearing!

    I have been pleased with the progress of this V-Groove design, that I may take this router all the way with electronics! So that I can have one in my shop, as it seems odd that I don't even use these routers that I build and sell so frequently!

    While working with my CAD drawings, I have been thinking about building a sturdy stand and cabinet underneath it! Then I can have a place for the electronics that's not going to be effected by the HOT flying metal chips from my big mill! For this reason, I never bring my laptops into the shop! Imagine a big old hot aluminum or steel chip melting it's way through the screen or keyboard

    That last pic is the money shot!

    Looks awesome. Very beefy.

    Cheers,

    A little more progress today!

    So far I have made the front & rear plates, which will be fastened to the "L" tracks with three 1/4-20 SHCS, and two 3/16" dia x 1" long dowel pins.
    Then I drilled & tapped all the #6-32 holes which fasten the Double-V tracks to the "L". and shortened the Double-V tracks from 24" to just under 23".
    After a trial assembly, I found the slide was a little tight, so I took some measurements, and re-cut the "L" where the V-Tracks are mounted. After removing .008" from each "L", the assembled unit was tracking nicely.
    During the design stage, I had to reverse engineer the V-Bearing & Track system, and decided to leave an additional .010" on the "L". I'm glad I did as it would have been .002" out of alignment, which would have required shimming the V-Tracks.
    Another item I have added is two 1/2" dia aluminum rails in the middle of the unit, one on top, and one underneath the slide block. This is to ensure the force of the lead screw does not push against the front & rear plates without having something to retain the force! The two rails will be finished sometime today.

    I have ordered bearings & thrust bearings with a .500" ID, for use on the ends of the lead screws.

    This morning I squared up the top T-Slot plate, it was 24 1/4 x 24 1/4 so I removed about 1/8" from all edges.
    Because of the size of the plate, I can only do one edge at a time. Then I have to re-position the plate on the mill, dial in the previous cut edge so it's parallel to the mills axis, clamp and mill to finish size. Then I have to rotate it 90°, dial the plate parallel to the mills y-axis, clamp and cut one edge. Leaving one more edge to rotate, dial in, and mill parallel.

    The whole process took about 3.8 hours. While the mill was running, I slipped over to the lathe and made a few other parts for this big router!
    After my late lunch break, I'll go out and finish up a few T-slots. This is also a time consuming process, as I can only do a few slots per setup due to the mill's travel restrictions.

    All total, I'd estimate 18-24 hours to make one plate with all it's holes, slots and c-bores.

    nice design , looks great so far
    i was looking at the slide , could you not build that as a 3 piece assembly rather than one solid piece ,you could use shoulder bolts to bolt it together , you may save a fair amount of machine time and save on material costs

    A poet knows no boundary yet he is bound to the boundaries of ones own mind !! ........

    Thanks dertsap!
    That would have been too easy, and this is not a production machine! (Not on my budget anyway)


    After lunch I finished up the whole plate! Milled slots, drilled holes and deburred it!

    All I have to do now is wait for some screws & pins that have been ordered!

    The adjustable foot pads that I ordered from McMaster Carr arrived Friday evening, now I need to get some 3/8-16 flat head screws, and countersink the base rails to fasten the 6" long 1" dia legs I made in the lathe today!

    This Router is getting too heavy to move around, so I'll have to get a cart or wagon to transport it in my house!

    Now that the base is finished, I have been thinking about the side plates for the Y/Z axis. The offset of the plates is determined by the diameter of the spindle motor. otherwise the spindle will be off the front of the t-slot plate when the x-axis is at it's maximum. So now I need to decide which spindle motor!

    I have a 30000 RPM Makita Die Grinder with a 1/4" collet, and a 1.5" dia clamping surface. It is slender, but very noisy! Is there a better choice, like a Dewalt with 1/2" spindle?

    A couple suggestions.

    First, a 1000lb lift table has been a very handy and inexpensive addition to my shop.

    Second, somewhere on these boards was a nice review of the Bosch as a spindle choice. Very low runout.

    Best,

    BW
