I hadn’t given this a great deal of thought yet but now I am getting closer to being able to make chips I thought I better come up with a solution.
Right now my spoil board is a sheet of 18mm MDF sat on top of the worktop my MPCNC is fixed to.
I’ve done some research but, as with a lot of things, there is multiple paths I could take.
Below are the options I am aware of and some of my, uneducated, thoughts on them. I welcome any comments or suggestions from people who know more and have been using one or more of the options.
Screwing the stoke to the spoil board
This seems to be the simplest option but I can see repeated screwing’s weakening the spoil board over time allowing future screws to slip, also putting a screw in could warp the surface slightly in that area making the stock not sit flush.
Masking tape + superglue
My concerns on this would be the tape or glue letting go and ruining the workpiece and damaging the tool.
Regular spaced holes with captive nuts on the underside of the spoil board.
This seems to be used a lot on other machines. I don’t know how well this would work for me as my spoil board is sat flat on a worktop meaning that there isn’t any space to allow bolts to pass through my board. If a bolt were too long it would ground out and start lifting my spoil board.
Cutting the board up into strips and fitting T-Track between them.
Something else I have seen one a lot of other machines. This would be the most expensive option in the first instance as I would need to buy several meters worth of the T-Track. It does have the benefit of allowing small sections of spoil board to be replaced over time rather than having to swap the entire sheet every time it wears out.
Out of all the above options I am starting to lean towards the T-Track as, although its the most expensive option, its seems to be quite flexible in terms of way to clamp and has the added benefit of saving money in the long term when I get to the point of having to replace sections of spoil board.
Please let me know what options you have tried and how you find them.
