Just got the news my woodworker is arriving today what size screws do I need to mount to my table
@Machinist helped me by giving me the following from the holes on the “Machinist” which I assume will be the same:
“…the c’bore diameter is 15mm, and the length of the 8mm hole is 15mm top to bottom.”
Thank you headed to store to get some now
It does come with screws for mounting to the table, although I wouldn’t use them. For some reason, they send Tapcon concrete screws for mounting… great for concrete, but they don’t have enough bite for wood.
I had no idea why they sent those. But I used three of them to mount a junction box on my concrete basement wall for my new 2x 20A power for the CNC. The only other tapcons I had laying around were 2.5” so it worked out nice.
Has anyone found other mounting screws they feel are a better match?
I just mounted my 1F and wondered about the screws, especially since I’m doing a flip-up table. Shear strength (for hanging sideways on flip table) on the tapcons seems OK I guess? I may be over thinking it.
FWIW I’m screwing into 1.5" of wood-like materials (3/4" MDF and 3/4" good plywood).
So I used Power Pro #8Ă—1-1/2" screws https://www.lowes.com/pd/Power-Pro-One-8-x-1-1-2-in-Yellow-Zinc-Wafer-Interior-Multi-Material-Screws-1-lb/1000310309
I have a flip cart and they are holding great
I will use bolts thru the table with washers and nuts on the underside. Screws into mdf, not good, especially with tilting table.
I used the tapcon screws included with the machine, attached to my table and there is no way its going to move. They are plenty strong enough for this application.
I’m literally in the process right now of bolting my machine to the enclosure. It’s not flipping so that’s not a concern although I was taken a little aback when I realized the " special blue screws " were Tapcons , and three of them were bugles while the rest were bolt heads. What I was concerned about was ensuring the screws went in dead center in their holes so they wouldn’t pull the foot out of alignment as they were tightened down. Found a screw bore that fit the hole perfectly, just loosened the screw on the side of it so the bit slid easily, fit it in the screw hole, a light tap with a hammer marks the spot, predrill with a long drill bit and - presto- perfection.
what were those screws that fit perfectly?
Somehow I thought from the photos that those blue screws were special, I don’t know, gun metal blue or blued steel like they do for expensive hand built watch hands. The first three tapcons I put on were the bugle heads. The rest were bolt heads with a slot for a flat head screwdriver. I struggled to put one in and then tossed the rest. I loathe slotted screws. It’s a Canadian thing. All the rest of the holes were screwed down with #10 Robertson 1 1/4 " flatheads. When I referred to perfection, it was the technique I used to ensure the screws were centered in the hole so as not to pull the foot out of alignment.
Oops, sorry. I see what your asking now. The screw bore I referred to was a counter bore, adjustable so you can change the depth the hole for the screw is sunk. I have a full set for different size screws but I don’t know what size the one I used was, they’re not marked. Looked to be for a #6 screw at a guess.
