Another dimension question - what is the cutting offset to the mounting footprint in the front to back directions?
In other words, how far forward is the collet center from the y rail mounting back edge when machine is fully back?
Also- how far forward of the y rail mounting front edge is the collet center when fully forward?
Asking so that I can design the table top to allow end grain routing for dovetails and not sure how much cutout I would need in either position.
I might have missed it in this thread - what is the diameter of the mounting holes? Looks like regular deck screws can be used - so about #8 screws; guessing the holes are #10 or larger (maybe 0.25")?
Oh, also interested in the front to back cutting dimensions too.
I was watching Ben Meyerās new enclosure video, and he measured from the back of the Y motors to the front of the dust boot, concluding that about 49" would be enough room to enclose it all.
@Machinist did you get an updated answer here? Iām curious as well. I measured my inside dimension as pretty close to the 20.049". Also, which size bolts did you use on the feet? I think 5/16" would be fine, but maybe thereās a better metric size?
Yes, those dimensions were good, and what I designed my base to. The mounting feet holes are 8mm, so either M8 screws or 5/16" either one would work just fine.
I have been following the conversation about bolts for the feet. I had planned on screwing them down, is this a BAD plan if I need bolts I could drill access holes in bottom layer of torsion box or go for threaded rod total thickness of torsion box is about 8ā.
Please comment
David, I would go with either wood screws, or access holes with bolts & nuts thru the top layer of wood. Iām not fond of the threaded rod option because you will be tightening down on what is essentially unsupported layers of plywood. You can achieve more holding power by bolting thru one layer of plywood & using access holes in the bottom to access the nuts. Optionally, you could insert these from the bottom & not need the nuts. Obviously, youād still need the access holes for installation.
You are correct, I think I am going with bolts and lock nuts with access holes. Are the holes in the feet countersunk or is it a flat surface for a hex head and flat washer.
The holes in the feet are counterbored (flat surface, not countersunk āVā) to 15mm dia. So, the holes are 8mm dia. and the length of the holes are 15mm, and you have 15mm dia. to work with for bolt head & washer. If you go with M8 or 5/16 bolts, there will likely not be enough room for a washer in the 15mm dia. unless you found some small dia. ones. You could also go with 1/4" bolts & have plenty of room for standard washers.
Thank you Bill,
I will have to check my own stock and if I donāt have something that will work I will hunt for the 8mm and small flat washer. The measurements are a exactly what I need!

This is not exactly a dimension question but could be a factor for those building hoisted or fold up tablesā¦what is the weight of these machines? Iām getting a machinist.
Shipping weight is listed as 135 lbs. (per people getting the woodworker). I was surprised to see my machinist show up with the same 135 lb. on the shipping notification. Would have expected it to be closer to maybe 100 lbs. But I hope that people building fold-up tables are NOT using the screws that come with it for attaching.
I am keen to make a steel framed table for by backordered onefinity woodworker (should receive it in a few months). I am keen to drill and tap the screwdown pattern directly into steel. The dimensions donāt seem line up with anything nice imperially or metrically (e.g 1.611"? 40.9194mm?). Are the dimensions of the bolt hole patterns accurate?
If youāre referring to the 4 corner Y rail assembly block mounting holes, yes, they are accurate (albeit not with ācommonā dimensions). They were accurate for my Machinist, anyway. Would assume so with the Woodworker as well.
I checked the massproperties in CAD, and the longer rails weigh just about 4 lbs. ea. more on the woodworker (5.88 lbs. vs. 9.73 lbs.). Assuming thereās maybe a couple lbs. ea. more for the longer ballscrews, that would be roughly 33 lbs. difference between the 2 machine types (7 rails & 3 screws). There may not be that much difference in shipping cost, so the relatively few Machinists they sell compared to Woodworker may not have been enough to layer in the potential errors by creating 2 different shipping weights. I dunno though, Iād have to defer to the experts that actually make & ship the machine.
