Gustave Build : Woodworking router

[Gustave]

update in orange

------------------------------- Update design (more detail in the discussion)


Modification from the initial design :
- Widening the table : 670mm > 800mm
- The table will finally be aluminum > (160x80 + 40x80), I keep a steel base
- Reduction of the steel profil section 100x100x5 > 80x80x5 for the base
- Base is cut in several parts
- Thickness of the gantry side plate : Aluminium 20mm -> 15mm (advice from Jazz in #5)
- HGW carriage on X and Y axis (advice from Jazz in #2)
- Ribs of the Z movable part is now turn on the Z fixes plate (more clearance around the spindle)
- Clearance between Z carriage 107mm > 170mm (advice from Jazz in #2)
- Clearance between X carriage 245mm -> 295mm
- Height of the gantry 360mm -> 400mm
- Indirect transmission on all ball screw 2:1 or 3:1


------------------------------- Description of the projet and Initial design
Hi Everbody,
After reading a lot and a lot of thread ! It is time to share my project ... I am a woodworker hobbyist and the machine will be 80% intended for wood panel and hardwood (occasionally aluminium if the machine could handle it). So the precision target is about 1/10 to 3/10mm and free speed likely 10m/min. The machine need to be taken to piece to go through a door and the elements could be carry without machine. I would like to use the table of the machine as workbench when it is not used for this reason I am not going on a canyon type of machine.

Here are some pictures and detail on the present version :



Here are some of my concerns :

1. My TIG welder is 30% at 150A so 5mm of steel is probably the thicker width it could handle so I choose 100X100X5mm thick steel profil.
2. Probable need to put extra plate in the 100x100 X profil to have more steel thickness for bolting the rail ?
   Bed and structure are independant part that are bolted together through a 100x100 cube spacing. I am not used to weld sutch structure but I thing that the distortion is not really an issue the support and will be corrected by West System resin epoxy for the bed. What you opinion on that point, do you recommend to cut the structure in smallest part and use bolt ?
3. I am planning to use WestSystem resin to set my X axis on the same plane and the bed at the same time, need approx 2L (see pitcture). In France I don’t find small West System pack than 5kg 105 + 1.4kg 109 (270euros).
4. What are the essential measurement tools i think i will place an order soon. (I already bought a rule of 1m class 0)
5. Some doubts on the ball screw diameters : 25 or 32mm ball screw 10mm pitch for the X, 20mm or 25mm ball screw 10mm pitch for the Y and 16mm ball screw 5mm pitch for the Z
6. HGH20 or HGH25 on the X (or HGW)
7. Could I have racking issue with an only central ball screw ?
8. General opinion on the design and if the machine I correctly balanced ? Weakness point ?
