So I've been reading here for a long time to get some build ideas. I figure before I start making full-out guitars, I should start with something simpler and tackle a lap steel. I've always wanted one, so it works out. Here's what I have so far, and what I'm envisioning. I will post my drawings once I can get them scanned to get some feedback on if I'm setting something up incorrectly: My wood is a slab of 1 7/8 inch thick ash, 3 feet long by 8 inches on one end, tapering out to 10 inches on the other end. I bought it from the local reuse center, which sells reclaimed wood from urban treecutting. kiln-dried and everything. cost me $32, which seemed pretty reasonable. I've decided to go with a single P90 for the pickup. I went with the soapbar configuration. I will be having tone and volume knobs, 500k pots, .022uf cap. I'm debating whether to go with the LP Jr. wraparound bridge I bought from GFS or just use the aluminum angle stock i'm using on the bridge and do a string-through configuration. I'm inclined to use the LP bridge to make things simpler, but I'd also like some practice drilling ferrule holes. I will be building a MDF template to route from next weekend. Should also be a good way to get into routing, as I've never done it before. I really only have three major questions (and subquestions, i guess): 1. How deep should I rout the pickup cavity with a soapbar P90? How close should the pickup be to the strings for a P90 on a lap steel? Also, how close should it be to the bridge? The action will be somewhere around 3/8 to 1/2 of an inch. 2. What's the best/easiest way to mark out tuner holes on the headstock when I'm doing the drawings/template? I have 3-on-a-side plate tuners from GFS, so I will have to be drilling 9mm holes. I'm just nervous I'll drill them incorrectly and they won't fit. Also, how far is too far from the nut for the top and bottom tuners, and with the higher action of the lap steel nut (I'm basing my design off the of the buildyourownguitar.com lap steel plan), will a string tree be necessary? 3. I'm a bit perplexed by a grounding wire to the bridge. Is that necessary/how do I drill the hole/where do i mount the wire to the bridge? Wouldn't just grounding the electronics to the ?volume? pot be necessary? I'm not afraid of soldering, but I've never soldered a guitar before. I'm also assuming I'm going to have to shield everything pretty thoroughly. That's all I have for now, I appreciate any help anyone can give me. There will definitely be a lot more as the project progresses. I've gotten to the point as a player where I'm finding it hard to find commercial guitars that fit exactly what i want, so it's time to start building my own! There will, of course, be pictures along the way. Thanks!
