Regardless of what level you use to do the job(more is better)can we set a std for positions where the levels should read in spec. What is spec? Is spec good enough? This is not a question for me, it is a question to see if we can establish a std for this operation. Talk of a mech association etc is very good. Let's see what we can do to set this std. To me, this is more than easy to establish. All I am referring to is where the levels should be placed every time a table is set up. NOT how to level a table.
If we could establish this I would be all for a MECH association of sorts. If we can't do this, there is no hope for any type of mech union or whatever.
You can use an excel spreadsheet to highlight where levels should be placed. This would be the first std of many that needs to be estabished.
A task like this is normal SOP for many disciplines. This should be completed ASAP> Then we can choose another topic to formalize. This is an easy task, failure to establish it now resides with you who are reading this. Lets get this forum on track to improve our trade. There really isn't anything thats more important.
Good morning John,
Could you first produce the standard for the spread sheet (excel), perhaps a link to a template that we could all use. Sort of a standard for the standard....
Are we going to have a board of review? How do we arrive at a consensus of which system or placement is THE STANDARD? Since we have no union, guild, governing body, standards and practices guidelines how do we take the gathered information and convert or establish it as a standard? It sort of a chicken and the egg paradox. I'm not trying to be negative, but I think the organization must be created first, in order for any process or procedure to be a standard. Without out this organization we will continue as we have here at AZ and elsewhere simply exchanging ideas rather than setting standards.
I carry 2 12 inch Starrett 98 machinist's levels on the road with me. I level each section of a three piece slate measured in the following locations. The span width ways in the center at the foot and seam, from the edge of the slate at the "ball track" (5 inches in from the edge) to the center both across and head to foot on both sides of the slate, and finally from the center of the slate to the seam edge and from the center to the foot edge. This system has served me well over the years. I'm not saying it's the best system just the best one I've found for three piece slate tables.
When I'm working on Brunswick Metro's or Gabriel signature pro's or older Diamond pro's or tables that require leveling with the rails bolted to the slates before the cloth is installed the fixed locations can vary it's more of a "live" process. Glen demonstrated this system at the Alsip seminar on the 7 ft Diamond smart table using the "low low" leveling system with a single level and directional arrows. If you were to use separate levels at all the locations you would need 27, 8 inch Starretts. I do believe that is how Diamond levels the tables at the factory with their leveling system. It's just not practical for me to buy or carry 27 machinist's levels.
The point is that we need many "Standards" that address the various situations and equipment that are encountered in the field. Not to mention billiard tables, snooker tables, four piece slate tables and one piece slate tables, all of which have their own slightly different locations for level reading and placement.
The gathering of the information is relatively easy. Standardizing it poses a much bigger challange...JMO
