Your project is moving right along. You should be proud of it, It looks GREAT!!

pretty much done with the skates for what will be my Y axis for now..
I still need to add the gantry rail mounting holes, but I'm going to do some thinking on how I want to attach the gantry and how much offset to give the gantry in Z, and also how much offset in Y...


heres the latest on the skates, If you look through the build you can see how the skates will capture the rails..

Nice looking skates Bruce. Looks like they should travel well.

made some bearing blocks this am.

they measure 1.9x1.25x.3125 thick..

have an Idea floating around in my head, and went ahead and pushed the go button on it...
I ordered 10 .375 i.d./.875 o.d. flange bearings ($20 free shipping).. These will be for the drive on my y axis.. I will use .375 D-shaft with spur gear and belt and pulleys.. It should be pretty simple, the large gears are a little expensive at $19 each but should be maintenance free for the long haul..

I sawed material for the bearing blocks, squared the stock, drill bolt holes, drilled and reamed dowel pin holes on the opposite side for locating, and I also drilled and rough bored the bearing hole to .855. I'll bore the bearing bore to .874/.8745 (press fit for .875 bearing) and also counterbore one side to capture the bearing in the housing after the bearings come in the mail..

sorry for the crappy pictures

hi guys, been a week or so for this update.. had to dig a nasty, I mean nasty, enclosure out of a junk pile, but it was a freebie, and we like freebies.

I didnt take any before pics, but to let you now I had to break all the componets out of the enclosure with a grinder and cutoff wheel, I also had to weld in new pieces of tubing and drilled and tapped them to mount the component plate onto, also had to cut the side latches off and drill and tap holes for the side latches/clamps.
I got it cleaned up decently and painted the inside white, and the eclosure safety blue.. I got the power supply and driver board mounted, I put nylon standoffs under the power supply and driver board to raise them off the mounting plate..

took me about 3 days to get it cleaned up and painted to point in the pics, still need to drill a couple more holes, going to mount an outlet and sealed outlet cover plate on the enclosure so I'll have a plugin on the machine. I also plan on mounting an on/off switch to cut all power to the enclosure, and also a on/off switch on the power supply...

so far so good, a lot of work in this enclosure, a lot more than I initially thought it would be.... after i get it going I might pretty it up with some polished checkplate or maybe some polished stainless.. either that or shoot it with the largest shotgun I can get my hands on

Also my gear racks from Moore gear and timing belt pulleys from QTC come in friday, both places were excellent to deal with, good prices and pretty fast shipping... gear racks and timing pulleys were all very good quality and will order from both places again if i need to..

wahoo, now I have plenty to do... rack clamps, motor mounts,gear reduction setup, wiring and so on.. head is spinning now..

think I'll straighten the garage up tomorrow and and start cutting some material for the motor/mounts/gear reduction setup and do some planning/designing..

as far as stuff I still need is belts, which a friend is getting for free from the place he works, and also three pinion gearsI will also get those from hubbard cnc, he sells them for like $11.99 each, I knew I was forgetting something when I placed that last order... the drive shafts will be 3/8 ejector pin, I got the ejector pin free from work..


to add, there are only 3 sets of timing belt pulleys (3:1 ratio), the other set is on the work table and is for the z axis... I decided to go with a different ratio on the z axis, it will be a 4:1 reduction, its only traveling 6-8 inches, and I dont want to be lacking torque on Z, for drilling/milling..

Thats one of the reasons I'm building this table... I have some ideas floating around for some cross members and I plan on making some brake brackets and such..

Its a 27ford, real steel bucket, I built the frame about 16 yrs ago, about had it pretty much done, tore it all back down to redo it in a 60's style theme.
I have a built 700r4, 2800stall, forged flattop 355 chevy with tunnel ram and 2 x450 holleys, ford 9inch 3:70 gears.
I need a fuel tank and rear brakes and start building the shortened model A bed for it... color is a copper metallic with red pearl added to it..

It looks like the e-box has a fan in the lower left of the box are you going to install a fan?
