Have you tried to call the company, explaining your situtation ?
For my taste the framing between the lettering allows to much spacing between the letters. I understand why they had to do this, but never the l e s s,,,,,,,,
I made a report some time back what I did to remeidy this in my world, a little more complicated, but showing the differance to several friends & then offering the change to remake the ones I had made was a resounding OK. It also allowed me to letter the main topic (or their last name) in an arch which allowed the overall sign to me smaller with some space for intresting additions pertaining to the indivigals intrest. As true with CNC's machines. You do not see the CNC sign programs offering the,, l e t t e r s,,, spaced as such. Boils down to what ever flotes your boat, I supose.
As a side note: When I was ask if i could make some signs from several non woodworking friends at our RV over the fire get-to-gethers. ( and ironic a couple of woodworking buddy's also) I was talking to my next door neighbor about buying a Milescraft kit. "Hey some where I have one, will bring it over" was his reply. Well it was not all there,,,,the key components mising was there plastic bace plate & the bit centering tool. Call the factory explaining I would buy one, if nothing else just to see if the overall system would apeal to me, Sure was her reply.
I ended up buying my own kit later, their design kit & and an extra 2 1/2 lettering set. So they know what a little customer service could bring. Thing to get lost or mis-place over time, at least that was my neighbors reasoning also. He gained a new base plate & centering tool for the kit's use.
